<?php 

/**
 * This is where you would inject your sql into the database 
 * but we're just going to format it and send it back 
 */ 

foreach ($_GET['listItem'] as $position => $item)
{
    $sql[] = "UPDATE `table` SET `position` = $position WHERE `id` = $item"; 
}

print_r ($sql); 

?>

Hello,

i have a dumb question. How can i execute the update for each item in array?

Im referring to the last part (the_php.php) at the array $sql that i want to know how to execute the updates.

Thank you,

Nevermind i found the solution as $sql[] = mysqli_query($con,"UPDATE 'table' SET 'position' = $position WHERE id = $item");
