Drupal 7 - Add custom fields to Search API solr index

     This is blog describes about how to add custom field to Search API solr index in Drupal 7.

     Suppose we need a new field, we can add new fields for a content type at /admin/structure/content/types. Then all fields are showed at /admin/config/search/search_api/index/default_node_index/fields. Now you can add desired fields to solr index.

     Suppose you want to show custom field to Search API results but that field is not created for any specific content types. Is it possible in Search API? Yes you can done this with use of hook_entity_property_info_alter().

/**
 * Implement phponwebsites_get_nodecountviews_nid()
 *
 * Return count of views by particular nid
 */
function phponwebsites_get_nodecountviews_nid($nid) {
  $result = db_query("SELECT COUNT(*) as count FROM {nodeviewcount} WHERE nid=:nid", array(':nid' => $nid))->FetchAssoc();
  return $result['count'];
}

/**
 * Implements hook_entity_property_info_alter().
 */
function phponwebsites_entity_property_info_alter(&$info) {
  $info['node']['properties']['is_nodeviewcount'] = array(
    'type' => 'integer',
    'label' => t('Node view count'),
    'description' => t("Number of views."),
    'sanitized' => TRUE,
    'getter callback' => 'phponwebsites_get_is_nodeviewcount_callback',
  );
}

/**
 * Implement phponwebsites_get_is_nodeviewcount_callback()
 */
function phponwebsites_get_is_nodeviewcount_callback($item) {
  $count = phponwebsites_get_nodecountviews_nid($item->nid);
  $total = (int) $count;
  return $total;
}

          After added above code into your custom module, go to /admin/config/search/search_api/index/default_node_index/fields. Now you could see new custom field is displayed as in below images.

         Now you can add your custom field into search api solr index and index that field. The custom field is listed in views add field section. Now you can add custom field into search results.

Drupal 7 - Create menu tab programmatically

    This blog describes about how to create menu tab programmatically in drupal 7. We can create menu items using hook_menu().

Menu tab creation in Drupal 7:

     Consider below code snippet to create menu tab in drupal 7.

/**
 * Implement hook_menu()
 */
function phponwebsites_menu() {

  $items['test'] = array(
    'title' => t('Create Menu Tab'),
    'page callback' => 'testpage_tab1',
    'access callback' => TRUE,
  );

  $items['test/tab1'] = array(
    'title' => t('First Tab'),
    'type' => MENU_DEFAULT_LOCAL_TASK,
    'page callback' => 'testpage_tab1',
    'access callback' => TRUE,
  );

  $items['test/tab2'] = array(
    'title' => t('Second Tab'),
    'type' => MENU_LOCAL_TASK,
    'page callback' => 'testpage_tab2',
    'access callback' => TRUE,
  );

  $items['test/tab3'] = array(
    'title' => t('Third Tab'),
    'type' => MENU_LOCAL_TASK,
    'page callback' => 'testpage_tab3',
    'access callback' => TRUE,
  );

  return $items;
}

/**
 * Implement testpage_tab1()
 */
function testpage_tab1() {
  $str = t('Hi this is first tab');
  return $str;
}

/**
 * Implement testpage_tab2()
 */
function testpage_tab2() {
  $str = t('Hi this is second tab');
  return $str;
}

/**
 * Implement testpage_tab3()
 */
function testpage_tab3() {
  $str = t('Hi this is third tab');
  return $str;
}

Where,
   In hook_menu,
      Title – page title
      Type – type of menu item,
       MENU_CALLBACK, MENU_DEFAULT_LOCAL_TASK, MENU_LOCAL_TASK, MENU_LOCAL_ACTION, MENU_NORMAL_ITEM, MENU_SUGGESTED_ITEM are types of
menu item in drupal 7.

MENU_CALLBACK – register path for a menu item
MENU_DEFAULT_LOCAL_TASK – default tab for a menu
MENU_LOCAL_TASK – additional tabs for menu
MENU_LOCAL_ACTION – actions for menu items
MENU_NORMAL_ITEM – add menu item into any menus like main_menu, user_menu
MENU_SUGGESTED_ITEM – module may suggest menu items

Page callback – callback for a menu
Access callback – who can access the page

        Now i’ve hope you should know how to create menu tab programmatically in drupal 7.

Add class into menu item in drupal 7:

     
       Consider below program to add class into menu item in drupal 7.

/**
 * Implement hook_menu()
 */
function phponwebsites_menu() {
  $items['sample'] = array(
    'title' => t('Sample page'),
    'type' => MENU_NORMAL_ITEM,
    'menu_name' => 'main-menu',
    'page callback' => 'samplepage',
    'access callback' => TRUE,

        'class' => array('drupal-menu-class')
      )
   ),
  );

  return $items;
}

/**
 * Implement samplepage()
 */
function samplepage() {
  $str = t('Hi this is sample page');
  return $str;
}

Where,
     type – MENU_NORMAL_ITEM
     menu-name – name of the menu to add new link
     options – add any attributes like class, id

You need to clear cache to see created menu items with custom class into main menu.

Add multiple classes into menu item in drupal 7:

     Similarly you can add multiple classes into menu item using hook_menu() in drupal 7. Consider below program to add multiple
classes into menu item.

function phponwebsites_menu() {

Find prime numbers between 1 and 100 in PHP

        This blog describes how to find prime numbers between 1 and 100 using PHP. Prime number is a number which is divided by 1 and itself.  Consider the number 5. It is prime number because it can be divided by 1 and 5.

PHP program for prime numbers:

       Consider the below program which is used to find prime numbers from 1 to 100.

<?php
    for($i = 1; $i <= 100; $i++)
      $mm = 0;
      for($j = 2; $j <= $i/2; $j++) {
        //only not prime numbers
                if ($i % $j == 0) {
                  $mm++;
                  break;
                }
      }
      if ($mm == 0) {
                echo"$i is prime number<br/>";
      }
    }
  ?>

       In above program, if a number is divided by any number except 1 and itself, then it is not prime number. Otherwise it is a prime number.

        Now you got prime numbers between 1 and 100 using PHP.

Fibonacci series of given number in PHP

         This blog describes about how to find Fibonacci series of given number in PHP. Fibonacci series is a sequence of number generated by adding previous two numbers. If the given number is 'n', then Factorial of 'n' is defined as 'Fn'. In mathematical terms, Fibonacci series for 'n' number looks like this:

                                            Fn = Fn-1 + Fn-2;

         Where,
              F0 = 0;
              F1 = 1;

         Fibonacci series for 'n' number is calculated recursively by above formula.

Simple PHP program Fibonacci series:

         This is the simple PHP program for find Fibonacci series.

function fibonacci_series($n) {
  $f1 = -1;
  $f2 = 1;

  for ($i = 1; $i <= $n; $i++) {
    $f = $f1 + $f2;
    $f1 = $f2;
    $f2 = $f;
    echo "$f<br />";
  }
}

echo fibonacci_series(5);

         The above PHP program returns 0, 1, 1, 2, 3. As i said, Fibonacci series is a sequence of number generated by adding previous two numbers. In above program, we have generated Fibonacci series for 5.
We have assumed $f1 = -1; and $f2 = 1; We need to run for loop until 5.As per above program,

If $i = 1:
              $f = -1 + 1 = 0;
              $f1 = 1;
              $f2 = 0;

If $i = 2:
              $f = 1 + 0 = 1;
              $f1 = 0;
              $f2 = 1;

If $i = 3:
              $f = 0 + 1 = 1;
              $f1 = 1;
              $f2 = 1;

If $i = 4:
              $f = 1 + 1 = 2;
              $f1 = 1;
              $f2 = 2;

If $i = 5:
              $f = 1 + 2 = 3;
              $f1 = 2;
              $f2 = 3;

Fibonacci series for 'n' number in PHP:

         The below PHP program is used to find Fibonacci series of given number.

Factorial of given number in PHP

        This blog describes about how to find factorial of given number in PHP. The factorial is one of the maths concept. It is multiplication of numbers from 1 to given number. If the given number defined as 'n', then 'n' factorial represented as 'n!'. The factorial formula for 'n' number looks like:

                                             n! = 1 * 2 * 3 ... n;

For example, the factorial of 5 looks like this:

                                             5! = 1 * 2 * 3 * 4* 5  = 120;

Simple PHP program for Factorial:

      Consider the below example which is the sample PHP program for find factorial of number:

function factorial($a) {
  $fact = 1;
   for($i = 1; $i <= $a; $i++) {
     $fact = $fact * $i;
   }
   return $fact;
 }
 $f = factorial(4);
 echo $f;

     Where,
           'n' is 4.
           n! = 4! = 1 * 2 * 3 * 4 = 24.

Factorial for 'n' number in PHP:

      Consider the below example which is the PHP program for find factorial of given number. For example, if you enter 4, it will return factorial of 4. Like if you enter 'n' number, it will return factorial of 'n'.

For more details visit how to upload file or image using PHP. When i tried to upload images using Ajax with jQuery, i can't get it work. All of you may be face this problem. This blog describes how to upload file or image in PHP using jQuery with Ajax.

     Consider the following example for upload files using Ajax and PHP.

Html form for upload image:

   
      To upload file or image, your html form should be like below form:

<form name="multiform" id="multiform" action="#" method="POST" enctype="multipart/form-data">
    Image : <input type="file" name="file" id="file" /></br>
    <input  type="button" id="multi-post" value="Upload"></input>
</form>

  $("#multiform").submit(function(e) {

    var formObj = $(this);

   

    if(window.FormData !== undefined) {

      var formData = new FormData(this);

      $.ajax({

        url: 'upload.php', //url to process the sent data

        type: 'POST',     //form type

        data:  formData, //form data to send

        mimeType:"multipart/form-data",  //type of form data

        contentType: false,  //content type of form

        cache: false,  //disable cache the request page

        processData: false,  //to send DOMDcoument or non processed data file

        success: function(data, textStatus, jqXHR) {

          $("#er").html(data);

        },

        error: function(jqXHR, textStatus, errorThrown) {

          $("#er").html('textStatus=' + textStatus + ', errorThrown=' + errorThrown);

        }          

      });

   
      //reset file field after form submitted

      $('#file').val('')
      //prevent the page is refreshed

      e.preventDefault();

      //e.unbind();

    }

  });

  $("#multi-post").click(function() {

    //submit the form and send data

    $("#multiform").submit();

  });

});

      When user click the upload button, the form is submitted, ajax is called and send form data as well.

Html file with Ajax for upload image:

      We need to combine html form and ajax code to make a full html file for upload file or image. You may add some styles to html file in order to give attractive presence to users. After combined above all things, your html code should be like below one:

upload-ajax.html:

<html>

<head>

<style type="text/css">

 body {

 color:white;

 font-size:14px;

 }

 .contact {

    text-align:center;

    background: none repeat scroll 0% 0% #8FBF73;

    padding: 20px 10px;

    box-shadow: 1px 2px 1px #8FBF73;

    border-radius: 10px;

 width:520px;

 }

 #file {

    width: 250px;

    margin-bottom: 15px;

    background: none repeat scroll 0% 0% #AFCF9C;

    border: 1px solid #91B57C;

    height: 30px;

    color: #808080;

    border-radius: 8px;

    box-shadow: 1px 2px 3px;

    padding: 3px 4px;

}

#multi-post

{

    background:none repeat scroll 0% 0% #8FCB73;

    display: inline-block;

    padding: 5px 10px;

    line-height: 1.05em;

    box-shadow: 1px 2px 3px #8FCB73;

    border-radius: 8px;

    border: 1px solid #8FCB73;

    text-decoration: none;

    opacity: 0.9;

    cursor: pointer;

 color:white;

}

#er {

    color: #F00;

    text-align: center;

    margin: 10px 0px;

    font-size: 17px;

}

</style>

</head>

<body> 

<script type="text/javascript" src="../test/js/jquery-1.7.2.min.js"></script>

<script type="text/javascript">

$(document).ready(function(){

  $("#multiform").submit(function(e) {

    var formObj = $(this);

   

    if(window.FormData !== undefined) {

      var formData = new FormData(this);

      $.ajax({

        url: 'upload.php',

        type: 'POST',

        data:  formData,

        mimeType:"multipart/form-data",

        contentType: false,

        cache: false,

        processData:false,

        success: function(data, textStatus, jqXHR) {

          $("#er").html('<pre><code>'+data+'</code></pre>');

        },

        error: function(jqXHR, textStatus, errorThrown) {

          $("#er").html('textStatus=' + textStatus + ', errorThrown=' + errorThrown);

        }          

      });

      $('#file').val('')

      e.preventDefault();

      //e.unbind();

    }

  });

  $("#multi-post").click(function() {

    //sending form from here

    $("#multiform").submit();

    console.log();

  });

});

</script>

<div class="contact">

  <h1>Upload files using Ajax and PHP</h1>

  <div id="er"></div>

  <form name="multiform" id="multiform" action="#" method="POST" enctype="multipart/form-data">

    <input  type="button" id="multi-post" value="Upload"></input>

  </form>

</div>

</body>     

</html>

     
      When you view the upload-ajax.html in browser, it should be like below image:

 

PHP snippet for upload file:

      When ajax is called, url which is in ajax call received form data. Then the file or image is to be uploaded using following PHP code.

upload.php:

<?php

 $file=$_FILES['file']['name'];

 if($file!='')

 {

  //upload file

  move_uploaded_file($_FILES['file']['tmp_name'],$_SERVER['DOCUMENT_ROOT'].'/test/uploaded_img/'.$file);

  //check whether file is exists or not in a folder

  if(file_exists($_SERVER['DOCUMENT_ROOT'].'/test/uploaded_img/'.$file)) {

   echo'Uploaded successfully';

  }

  else {

   echo'File is not uploaded';

  }

 }

     Where,

        move_uploaded_file() - used to upload the file

        file_exists() - used to check whether the file is already exists in a folder or not after upload the file

        $_SERVER['DOCUMENT_ROOT'] - used to represent the directory 

        Now you can add either file or image using PHP and jQuery with Ajax.

Upload multiple files/images using PHP

                        You can upload single file and image easily in PHP. Now we are going to know how to upload multiple files and images using PHP. You can upload more than one images or files at the time using PHP. It can done using by array concepts.

Form for upload multiple images:

               

                     First you need to make form for upload more images. Your form should be like following:

<form action="#" method="post" enctype="multipart/form-data">
<input type="file" name="file[]" id="file" multiple="multiple">
<input type="file" name="file[]" id="file" multiple="multiple">
 <input type="submit" id="submit" name="submit" value="submit">
 </form>

                  You should add enctype="multipart/form-data" for upload files. You can see above where the name of file tag should be array like name="file[]" for store multiple values.

Upload multiple images using PHP:

                       Similarly upload single image, you will get image values by $_FILES['file']['name'] in PHP while submitting a form. You need temporary name of image to pass one of the parameter in move_uploaded_file() in order to upload files. If you've a single image, then you can upload easily by move_uploaded_file($_FILES['file']['tmp_name'],$name). But you need to upload multiple images. So you've to get values as an array. Then upload each image using loop. Consider the following example. Here it describes how to get temporary name of each image one by one using loop in PHP.

<?php
if(isset($_POST['submit']))
{
 $name=$_FILES['file']['name'];
 foreach($name as $val => $name1)
 {
   $file_name=$name1;
   $tmp=$_FILES['file']['tmp_name'][$val];
  move_uploaded_file($tmp,$_SERVER['DOCUMENT_ROOT'].'img/'.$file_name);
 }
}

?>
<html>
<body>
<form action="#" method="post" enctype="multipart/form-data">
<table>
<tr><td><input type="file" name="file[]" id="file" multiple="multiple"></td></tr>
<tr><td><input type="file" name="file[]" id="file" multiple="multiple"></td></tr>
<tr><td><input type="submit" id="submit" name="submit" value="submit"></td></tr>
</table>
</form>
</body>
</html>

             
     
     Where,
                move_uploaded_file() - to upload files to desired location.
                $_SERVER['DOCUMENT_ROOT'] gives the root directory of current script executing.
You can upload multiple files as well as images using this PHP script.

Create Search API like itunes Search API using PHP and MySQL

                      The Apple itunes provided a search API for retrieve app information from it. The Apple search API display result as JSON format. Do you want to know more information about Apple itunes search API, then visit iTunes Search API.

                      You can also create search API like Apple itunes search API if you know how to create JSON file using PHP. Due to this, you can provide search API for your websites. If you didn't know create JSON file using PHP and MySQL, then visit How to get output as JSON format using PHP and Mysql.

Generate Search API using PHP and MySQL

                       Lets see how to create search API using PHP.  Follow below steps to generate search API for your websites using PHP.

Step1: Connect MySQL database using PHP

                     Connect your MySQL database to get stored values from it using PHP. The PHP code for connect MySQL database is below:

 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('fitness') or die(mysql_error());

Step2: Get value from url using PHP

                     While user search something on your search API, you need to get those values for search from url. So only you can provide particular results from your MySQL database. This is done by below PHP code.

 $field=$_REQUEST['field'];
 $limit=$_REQUEST['limit'];

Step3: Make MySQL select query

                     After got values from url, you've to make MySQL query to select corresponding results from database. You can get zero or more than one values from urls for search. You should make MySQL query like below using PHP.

 if($field!='' && $limit!='')
 {
   $cond="where name='".$field."' order by id desc limit 0, $limit";
 }
 if($field=='' && $limit!='')
 {
   $cond="order by id desc limit 0, $limit";
 }
 if($field!='' && $limit=='')
 {
   $cond="where name='".$field."' order by id desc limit 0, 50";
 }
 if($field=='' && $limit=='')
 {
   $cond="order by id desc limit 0, 50";
 }
 $q=mysql_query("select * from f_img $cond") or die(mysql_error());

Step4: Add header for get output as JSON format

              You must add header type ato your PHP script for get output as JSON format. This is like below

 header('Content-Type: Application/json');

Step5: Add content to JSON file using PHP

               You need to create 2 array for create output as multidimensional array. Retrieve values from query result using mysql_fetch_array. Then you push values to array using array_push() in PHP. Finally encode the results to display output as JSON format using json_encode().

               The full PHP code for create search API is represented below,

<?php
 error_reporting('E_ALL ^ E_NOTICE');
 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('fitness') or die(mysql_error());
 $field=$_REQUEST['field'];
 $limit=$_REQUEST['limit'];
 if($field!='' && $limit!='')
 {
   $cond="where name='".$field."' order by id desc limit 0, $limit";
 }
 if($field=='' && $limit!='')
 {
   $cond="order by id desc limit 0, $limit";
 }
 if($field!='' && $limit=='')
 {
   $cond="where name='".$field."' order by id desc limit 0, 50";
 }
 if($field=='' && $limit=='')
 {
   $cond="order by id desc limit 0, 50";
 }
 $q=mysql_query("select * from user $cond") or die(mysql_error());
 header('Content-Type: Application/json');
 $details=array();
 $user=array();
 while($res=mysql_fetch_array($q))
 {
  $user['name']=$res['name'];
  $user['state']=$res['state'];
  $user['country']=$res['country'];
  array_push($details,$user);
 }
 //print_R($details);
 echo json_encode($details);

?>

           Your JSON output should be like below,

[
 {"name":"Clark","state":"California","country":"USA"},
 {"name":"Anderson","state":"Los Angeles","country":"USA"},
 {"name":"Smith","state":"London","country":"United Kingdom"},
 {"name":"Jones","state":"Cambridge","country":"United Kingdom"},
 {"name":"Nathan","state":"Franche Comte","country":"France"},
 {"name":"Marie","state":"Paris","country":"France"},
 {"name":"Nastya","state":"St Petersburg ","country":"Russia"},
 {"name":"Dima","state":"Moscow","country":"Russia"},
 {"name":"Linh","state":"Hanoi","country":"vietnam"},
 {"name":"Hoang","state":"Hai Phong","country":"vietnam"},
]

Step6 : .htaccess

                   Add following lines to your .htaccess file

RewriteRule ^search search.php [L]

                  Now you entered search on address bar, the .htaccess redirects you to search.php file. You can get search API using below url types.

                http://www.phponwebsites.com/search?field=nathan&limit=10
                http://www.phponwebsites.com/search?field=nathan
                http://www.phponwebsites.com/search?limit=10
                http://www.phponwebsites.com/search
