How to parse JSON data in jQuery Datatable

Step 1: we will create new profile_image column in employee table. This column will store profile image path.

  ALTER TABLE `employee` ADD `profile_image` VARCHAR(255) NOT NULL DEFAULT 'images/default_profile.png' AFTER `employee_age`; 

Step 2: Added profile_image column in $column array in response.php file.

  //define index of column
    $columns = array( 
    0 =>'id',
    1 =>'employee_name', 
    2 => 'employee_salary',
    3 => 'employee_age',
    4 =>'profile_image'
    );

  

Step 3: Added profile_image and Action column in HTML table header and footer heading in index.php file.

  <thead>
            <tr>
                <th>Empid</th>
                <th>Name</th>
         <th>Salary</th>
                <th>Age</th>
        <th>Image</th>
        <th>Action</th>
            </tr>
        </thead>
 
        <tfoot>
            <tr>
               <th>Empid</th>
                <th>Name</th>
        <th>Salary</th>
                <th>Age</th>
                <th>Image</th>
        <th>Action</th>
            </tr>
        </tfoot>

  

Step 4: We will user dataSrc callback jquery datatable function to parse JSON object.This function will take JSON data as a parameter which will returned from Ajax request.

$( document ).ready(function() {
  $('#employee_grid').DataTable({
     .....
      
         "ajax":{
            .....
        "dataSrc": function (jsonData) {
        for ( var i=0, len=jsonData.data.length ; i<len ; i++ ) {
        
        jsonData.data[i][4] = '<img src="https://phpflow.com/php/parse-json-data-jquery-datatable/"/>';
        jsonData.data[i][1] = '<a href="https://phpflow.com" target="_blank">'+jsonData.data[i][1]+'</a>';
        jsonData.data[i][5] = '<div class="btn-group" data-toggle="buttons"><a href="#" target="_blank" class="btn btn-primary btn-xs">Edit</a><a href="#" target="_blank" class="btn btn-primary btn-xs">Delete</a><a href="#" target="_blank" class="btn btn-primary btn-xs">View</a></div>';
        }
        
        return jsonData.data;
        }
       ....
          }
        });   
});

as you can see above code, I am adding following functionality,

1. Adding img html tag with profile_image column value
2. Adding href attribute on each name column value
3. Adding new column Action column which will take edit/delete and view anchor tag
