Question

I’m working on a page with many insert fields.
how can i shorten the following code?

$title_1 = $_POST['title_1'];
$content_1 = $_POST['content_1'];
$link_1 = $_POST['link_1'];
$img_link_1 = $_POST['img_link_1'];

$title_2 = $_POST['title_2'];
$content_2 = $_POST['content_2'];
$link_2 = $_POST['link_2'];
$img_link_2 = $_POST['img_link_2'];

$title_3 = $_POST['title_3'];
$content_3 = $_POST['content_3'];
$link_3 = $_POST['link_3'];
$img_link_3 = $_POST['img_link_3'];

Answer 1

You could loop through the $_POST array like this:

foreach ($_POST as $key => $value) {
    ${$key} = $value;
}

This will make your post variable like $_POST['title_1'] into $title_1

Remember your post names will have to be the exact names you want your variables to be referenced by.
