Question

An array containing the primary key values of a mysql table will be passed through an
ajax call to a php page and from the php page, rows with the primary keys in the array will be updated

js snippet:

<script type="text/javascript">

$(document).ready(function(){


    var my_array=[1,2.,4,5,6];

    $.post("array_post.php",{

        my_array:my_array

        },function(response){

            alert(response);
            }

    );



    });


</script>

‘id’ is the primary key.
array_post.php has :

$my_array=$_POST['my_array'];

$sql="UPDATE my_table SET my_col=1 WHERE id IN ($my_array)";

Bu that shows error.

I need the solution.

You need to transform your array to a string:

$sql="UPDATE my_table SET my_col=1 WHERE id IN (" . implode(',', $my_array) . ")";

And, you should seriously validate your input, not just use $_POST
