How to solve "notice array to string conversion in C" error in php and javascript? -

so trying send "id" of selected row in datatable in javascript php page delete database.

var ids = $.map(table.rows('.selected').data(), function (item) {     return item[0]  }); 

the variable "ids" sent post method

$.post( "deleterow.php", { v1: ids });

but didn't worked try see response post method , says "notice array string conversion in c on line ... " line of php page writing delete query

$id = $_post["v1"]; $query = "delete `package` `id` = '$id'"; 

the whole php page works fine when trying other values.

because send array here:

$.post( "deleterow.php", { v1: ids }); 

so v1 contains array of elements. in php code treat single element:

$id = $_post["v1"]; 

hence notice array string conversion.

if send array of elements, have array , treat array. create correct sql string should append each id, this:

$ids = json_decode($_post["v1"]); $query = "delete `package` where"; $first = true; foreach ($ids $id) {     if ($first) {         $first = false;     } else {         $query += " or";     }     $query += " `id` = '$id'" } 

this way loop array , append id = id each array element.

now, this important, code prone sql injection, bad security problem. read more info this: how can prevent sql injection in php?
