如何使用複選框在php中刪除記錄？

Question

需要刪除記錄，這裏是我的代碼：

<input type="submit" name="delete" value="delete"/> 
<?php 
    if(isset($_POST['delete'])) 
    { 
     $cnt=array(); 
     $cnt=count($_POST['chkbox']); 
     for($i=0;$i<$cnt;$i++) 
     { 
      $del_id=$_POST['chkbox'][$i]; 
      $query="DELETE FROM menu_detail WHERE vt_id=".$del_id; 
      mysql_query($query); 
     } 
    } 
?> 
// I draw checkboxes using this where as I m fetching data from table... 
<?php 
    $col = "row0"; $i = 0; $a=1; 
    while($row = mysql_fetch_array($retval, MYSQL_ASSOC)) { 
    if ($i == 0) { $col = "row0"; $i = 1; } else { $col = ""; $i = 0; } 
?> 
<tr class="<?php echo $col; ?>"> 
<td> 
    <input type="checkbox" name="chkbox" value="checkbox[<?php echo $row['vt_id']?>]" /> 
</td> 

看圖像會給你一個想法，我是卡

看看

 $tableRow = array("id","name","code"): // assume It must from Database 

     <form action="your_action.php" method="post" id="bulkDel" > 

     <table> 
       <thead> 
         <th><input type="checkbox" id="checkAll" /></th> 
         <th>....</th> <!--and so on--> 
       </thead> 
      <?php 
       foreach($tableRow as $row){ 
         ?> 
        <tr> 
          <td> <input tyep="checkbox" name="check[]" /></td> 
          <td>.....</td> <!-- and so on --> 
        </tr> 

        <?php 

       } 
      ?> 

     </table> 
     <a href="javascript:void(0);"id="bulkDeleteBut" >Delete selected</a> 
    </form> 

    // jquery check all checkboxes 

    $(document).on('click','#checkAll',function(){ 
        $('input[name="check[]"]').prop('checked',$(this).is(":checked")); 
    }); 


$(document).on('click','#bulkDeleteBut',function(){ 
      var len = $('input[name="check[]"]')..serializeArray().length; 
      if(len>0){ 
        $('#bulkDel').submit(); 
      }else{ 
       alert("Check atleast one record"); 
      } 
}); 


// server side php 
    if(isset($_POST['check'])){ 
     $ar = $_POST['check']; 
     foreach($ar as $primary_key){ 
      // perform mysql delete query and return back to table page 
     } 
    }
