What's wrong with my code. It display the followin error message in the drop-down field:
Fatal error: Call to undefined function option_selected() in PHP in C:\xampp\htdocs\imageconcert/index.php on line 27
Here's the code:
<?php
if (isset($_GET["target"]))
{
function option_selected($target, $value)
{
$v=$_POST[$target];
if ($v == $target)
{
$selected="selected";
}
echo $selected;
}
}
?>
