delete row with ajax function and php

Question

i have a table with mysql Data,i add a trash button and i want remove each row when trash button is clicked with ajax function, this is my html:

  <table border="1">
    <?php
$sql ="SELECT * FROM music";
$result = mysql_query($sql) or die(mysql_error());

while($row = mysql_fetch_object($result)){

    echo '<tr><td>'.$row->file_name.'</td><td>'.$row->composer.'</td><td>'.$row->lyric.'</td><td>'.$row->music_thumb.'</td><td>'.'

    <a href="#" id="'.$row->msuic_id.'" class="trash" >
    جذف کردن
    </a>

    '.'</td></tr>';
    }

?>
  </table>

and my ajax function here:

$(function(){
        $('.trash').click(function(){
            var del_id= $(this).attr('id');
            var $ele = $(this).parent().parent();
            $.ajax({
                type:'POST',
                url:'delete.php',
                data:del_id,
                success: function(data){
                    if(data=="YES"){
                        $ele.fadeOut().remove();
                        }else{
                            alert("can't delete the row")
                            }
                    }

                })
            })
    });

and also my "delete.php" page here:

<?php
include('../db_inc.php');
$music_number = "POST['del_id']";
echo '$music_number';
$qry = "DELETE FROM music WHERE msuic_id ='$music_number'";
$result=mysql_query($qry);

?>

i think my problem is ajax function; thanks

Answer 1

try this

$.ajax({
    type:'POST',
    url:'delete.php',
    data:{del_id:del_id},
    success: function(data){
         if(data=="YES"){
             $ele.fadeOut().remove();
         }else{
             alert("can't delete the row")
         }
    }

     })
})

and also change

$music_number = "POST['del_id']";

to

$music_number = $_POST['del_id'];
