PHP “header (location)” inside IFRAME, to load in _top location?

Question

I have a simple form which is inside IFRAME. When user click on SUBMIT, it redirects to a specific page on my server. The function I use for the redirect is

Answer 1

In the page that you want to load in _top, add the follow code in the header

<script type="text/javascript">
if (top != self) top.location.href = location.href;
</script>

Answer 2

You are not able to achieve the desired effect in PHP. This is something you'd have to do from JavaScript or add target attribute to <form>:

<form ... target="_top">

Answer 3

You can either link to the page using <a href="pagename.php?Break=Y">Break Out</a> or use code

<?php header("Location: pagename.php?Break=Y"); ?>

You then use the following code in the header of the page with

if(isset($_GET['Break'])) // 
    {
    $BreakFrame = true;
    $BreakToPage = "pagename.php";

    }

<script language="JavaScript" type="text/javascript">
function changeURL( url ) {
    document.location = url;
}
</script>

<?php if($BreakFrame) { ?>

<script language="JavaScript" type="text/javascript">
parent.changeURL('<?=$BreakToPage?>' );
</script>

<? }?>

Answer 4

A simple way directly in PHP to redirect the parent page rather than the iframe:

echo "<script>top.window.location = '/mynewpage.php'</script>";
die;

The die; isn't necessarily necessary, but it is good "just in case" to prevent the script from continuing any further, for example, if javascript is disabled in the user's browser.

Answer 5

For CakePHP 4, to redirect your parent page just add option 'target'=>'_top' in your iframe's link:

Example:

 <?= $this->Html->link(__('Redirect Parent'), ['controller' => 'Users', 'action' => 'view'], ['target'=>'_top']) ?>

All the best!

Answer 6

we can use javascript like this :

target.window.location='locationpage.html';
top.window.location='mypage2.html';
