Cakephp Does Not Redirect on the Online Server

Question

Good morning!

I’m using the cakephp framework, but I’m having a problem with no solution so far... I have a login controller, commented all the login code and left only the tree

$this->redirect( array('controller' => 'nomedocontorller', 'action' => 'home') );

On the localhost this command works normally, I can direct the url, but when I put it on the online server I simply get a blank page and no error message.

I’ve checked spaces in Index, Routes, Controller and View files, but no spaces before the php opening tag I’ve tried opening php only with

<?

I already uploaded a new cakephp framework to the server to test if the problem was hidden in any of the files, but msm with the default cakephp files continued not to direct.
I’ve already released debug mode to print errors, but msm so no errors are reported, neither visually nor in the bug logo.

Answer 1

After 3 days fighting and some "sleepless" nights,.

Today I woke up inspired to solve this problem and started searching the project for php tags that had empty spaces before or after opening/closing.

For my happiness, I found around 5 files that had this problem, after fixing these files it seems that the targeting and session came back to work.

Solution: Search for php tags that were opened/closed before or after tags
Example:

(quebra de linha ou espaço)
<?php

or

?>
(quebra de linha ou espaço)

After removing these occurrences, it seems that everything is back to normal.
I had one more steering problem, but I think this is a little different.

Thanks for all your help!

This problem is common when there are sent headers. In place of redirect, try using the following and see which error is returned:

<?php header( 'Location: http://www.google.com/' ) ; ?>

When using redirect, it’s good practice to add it to Return:

return $this->redirect(array('action' => 'index'));

In your action, add the debug below and note which return:

if (headers_sent($file, $line)) {
    exit("headers were already sent in file: {$file}, line number: {$line}");
}
