PHP "header (location)" inside IFRAME, to load in _top location? - php

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
header ('Location: mypage2.html');
exit ();
But I want the new page to open in _top location, not inside the same IFRAME that I use. How can I tell the browser to open the new page in _top not inside the IFRAME?
Thanks in advance.

Answer 1

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 2

You can use javascript to access the parent. You could echo out javascript in your PHP.. so your parent page has this:
function changeURL( url ) {
document.location = url;
}
and in your php script, you echo
<script>
parent.changeURL('mypage2.html' );
</script>
The reason you can't call parent.document.location is because it's read only - you have to have a function available on the parent to do it.

Answer 3

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 4

we can use javascript like this :
target.window.location='locationpage.html';
top.window.location='mypage2.html';

Answer 5

The best and simplest thing to do is to use the form target element
<form action="..." target="_top">
<form action="..." target="_parent">
either of the target parameters works fine

Answer 6

You can either link to the page using Break Out 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 7

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 8

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 9

You can add multiple headers to your redirect.
I use a little function that I created with this in mind.
public function redirect($url){
header('Window-target: _top');
header('Location:' . $url, true, 303);
exit();
}
