Question

Im new to php..I had used GridView control in asp.net for Listing records.

Now I want to use a control in php to list the records with checkbox options to select them for deletion and also page enabled. Can anyone guide a beginner on how to do this?

Thanks in advance.

Your idea consists of two things; a table and a php-file that processes the input from the table.

File: table.php

<form method="post" action="process.php">
   <table>
      <thead> 
         <tr>
           <th>Title</th>
           <th>Activate</th>
           <th>Delete</th>
         </tr>
      </thead>
      <?php foreach( $records as $record ): ?>
         <tr>
            <td><?php echo $record['title']; ?></td>
            <td><input type="checkbox" name="activate_ids[]" value="<?php echo $record['id']; ?>" /></td>
            <td><input type="checkbox" name="delete_ids[]" value="<?php echo $record['id']; ?>" /></td>
         </tr>
      <?php endforeach; ?>
    </table>
 </form>

File: process.php

<?php

    //Gather the $_POST
    $activate_ids = $_POST['activate_ids'];
    $delete_ids = $_POST['delete_ids'];

    //Let's make sure we only get ints
    for($i = 0; $i < count($activate_ids); $i++)$activate_ids[$i] = intval($activated_ids[$i]);        
    for($i = 0; $i < count($delete_ids); $i++)$delete_ids[$i] = intval($delete_ids[$i]);

    //Get the ids
    $activate_ids_string = implode(',', $activate_ids);
    $delete_ids_string = implode(',', $delete_ids);

    //Make sure we don't have '' as a parameter for SQL
    if( $activate_ids_string == '' ) $activate_ids_string = 0
    if( $delete_ids_string == '' ) $delete_ids_string = 0;

    //UPDATE the table
    $sql_activate = 'UPDATE Records SET active=1 WHERE id IN (' . $activate_ids_string . ')';
    $sql_delete = 'DELETE FROM Records WHERE id IN (' . $delete_ids_string . ')';

    //Execute the queries and get the # of affected rows
    $aff_rows_activate = mysql_num_rows(mysql_query($sql_activate));
    $aff_rows_delete = mysql_num_rows(mysql_query($sql_delete));

    //Last but not least, output how it went for both queries
    if( $aff_rows_activate === 1 ) echo 'Activated one record.';
    else echo 'Activated ' , $aff_rows_activate, ' records.';
    if( $aff_rows_delete === 1 ) echo 'Deleted one record.';
    else echo 'Deleted ' , $aff_rows_activate, ' records.';

?>

I haven’t had a chance to try out the code above, so there might still be a couple of syntax errors in it – however, you should be able to get an idea of what you need to do to achieve the results that you want.
