记录未从数据库中删除

Question

I am using following code to show MySQL records on a web site table. This is the column whith the delete button:

<td align="center"><a id="<?php echo $row['id_peticion']; ?>" class="delete-link" href="#" title="Delete">
            <img src="delete.png" width="20px" />
            </a></td>

This is the JS code called when user clicks on the delete button:

/* Data Delete Starts Here */
    $(".delete-link").click(function()
    {
        var id = $(this).attr("id");
        var del_id = id;
        var parent = $(this).parent("td").parent("tr");
        if(confirm('Seguro que quieres borrar la petición # = ' +del_id))
        {
            $.post('delete.php', {'del_id':del_id}, function(data)
            {
                parent.fadeOut('slow');
            }); 
        }
        return false;
    });
    /* Data Delete Ends Here */

And this is the code from delete.php

<?php
include_once 'dbconfig.php';

if($_POST['id_peticion'])
{
    $id = $_POST['id_peticion'];    
    $stmt=$db_con->prepare("DELETE FROM tbpeticiones WHERE id_peticion=:id");
    $stmt->execute(array(':id'=>$id));  
}
?>

When clicked, the record dissapears from the table but is not deleted from the database.

I cannot find the reason why... Thank you

Answer 1

您的帖子键是jquery中指定的del_id而不是id_peticion ：

$.post('delete.php', {'del_id':del_id}, function(data)

Answer 2

You are checking for $_POST['id_peticion'] while the delete id is gonna be in $_POST['del_id'] . Change your code to :

if($_POST['del_id'])
{
    $id = $_POST['del_id'];    
    $stmt=$db_con->prepare("DELETE FROM tbpeticiones WHERE id_peticion=:id");
    $stmt->execute(array(':id'=>$id));  
}
