Question

PHP Controller redirection isn't working?

Asked by: snowball77

Hi there,
I have set up a login process here:
http://widowspeak.com.au/index.php

If you login you go through the process etc but once you login the page it redirects to is BLANK!!

I set up the redirection to go to:

// Check to see if they're logged in, because they don't need activating!
            if ($user->get('id')) {
                  // They're already logged in, so redirect them to the home page
                  $mainframe->redirect( 'index.php?option=com_joomunity&Itemid=57' );
            }

            if ($allowUserRegistration == '0' || $userActivation == '0') {
                  JError::raiseError( 403, JText::_( 'Access Forbidden' ));
                  return;
            }

However it doesn't go to this page
http://widowspeak.com.au/index.php?option=com_joomunity&Itemid=57

as I requested?

What am I doing wrong?

I have attached the whole controller.php page that controls the login process.
I hope someone can help

A blank page usually means there was a PHP error and error reporting is supressed.

Check the error_log (apache), or the corresponding error log if you're using windows. That will most likely tell you what is going wrong.

by: snowball77Posted on 2009-07-20 at 00:06:33ID: 24892908

I did something to the code which you can read about here
http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/Q_24578126.html#a24892905

Did this change anything

by: kevin_uPosted on 2009-07-20 at 11:38:43ID: 24897667

It could have broken it, but really, you need to check for error messages. Do you know where to look for your error log? If not, let me know what web server is being used (iis? apache?) Then I can let you know how to display error messages right on the page that is failing.

by: snowball77Posted on 2009-07-20 at 12:52:06ID: 24898366

Is this the info you need?
Apache version      2.2.6 (Unix)
PHP version      5.2.5
MySQL version      4.1.22-standard

I don't know how to check the error log, but I would love to know how

by: kevin_uPosted on 2009-07-20 at 14:00:55ID: 24898997

Do you know where your server log files are? If so, there is a file called error_log, and it will contain the error messages.

Alternatively, if you want to modify .htaccess, you can add these lines to make php display errors on the page.

php_flag display_errors on
php_value error_reporting 2047

by: snowball77Posted on 2009-07-20 at 20:26:09ID: 24901138

hi there,
I need a little bit more explanation. Do I just write those two lines in the .htaccess and then how do I get the errors?

If I run the page will they just show up on the page, so everyone can see it?

by: kevin_uPosted on 2009-07-21 at 09:20:23ID: 24906401

yes you just write those two lines into .htaccess.

The errors will appear on the page itself, and everyone can see it, but so will you, so you can track down where the fix is needed. You can remove those lines (or comment them out) after you get the information you need.

by: snowball77Posted on 2009-07-21 at 12:41:17ID: 24908482

Hi There,
I actually found the error log. This is what it said
[16-Jul-2009 05:36:01] PHP Fatal error: Unsupported operand types in /home/widowspe/public_html/includes/router.php on line 141
[20-Jul-2009 12:27:37] PHP Fatal error: Unsupported operand types in /home/widowspe/public_html/includes/router.php on line 141
[20-Jul-2009 12:27:50] PHP Fatal error: Unsupported operand types in /home/widowspe/public_html/includes/router.php on line 141

I have attached the router.php code. It looks like this section is the offending code:
//Only an Itemid ? Get the full information from the itemid
            if(count($this->getVars()) == 1)
            {
                  $item = $menu->getItem($this->getVar('Itemid'));
                  $vars = $vars + $item->query;
            }

hmmm, so whats happening. I am going to try to add your code also to see if I can find something specific when I log on etc.

Hi Again,
I added the two lines you mentioned into .htaccess and when I tried to go to the webpage I got this error:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@widowspeak.com.au and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

by: kevin_uPosted on 2009-07-21 at 20:44:09ID: 24911422

ok, it means that your hosting provider isn't allowing you to those things to .htaccess.

Without knowing the error messages, I can't go much further.

of course remove those lines from htaccess.

Perhaps you'll want to close this question, or request attention to get some fresh eyes on this one.

by: RQuadlingPosted on 2009-07-24 at 08:02:34ID: 24935588

Hopefully you can confirm that line 141 is ...

$vars = $vars + $item->query;

The + wants to add 2 numbers together.

What are the types for $var and $item->query ?

Are they strings? Use $vars = $vars . $item->query;

Are they arrays? Use $vars[] = $item->query;

Are they something else?

If you are not sure, use the following debug lines (i.e. put them in, run the code, record the output, remove the lines).

var_dump($vars, $item->query);
die();

What do you get?

Hi,
I am not sure what you want from line 141?
In the controller.php you can see its:
//preform the logout action
$error = $mainframe->logout();

Anyway, where in the code that I have shown should I add the code you have written?
Should I put it at the end of the controller.php code then run the script??

by: RQuadlingPosted on 2009-07-27 at 04:12:06ID: 24950319

The code in your comment http://#24908482 on this question - line 141

The errors are in router.php

[16-Jul-2009 05:36:01] PHP Fatal error: Unsupported operand types in /home/widowspe/public_html/includes/router.php on line 141
[20-Jul-2009 12:27:37] PHP Fatal error: Unsupported operand types in /home/widowspe/public_html/includes/router.php on line 141
[20-Jul-2009 12:27:50] PHP Fatal error: Unsupported operand types in /home/widowspe/public_html/includes/router.php on line 141

Not the controller.

Line 141 is ...

$vars = $vars + $item->query;

...

and repeat my last message at this point.

by: snowball77Posted on 2009-07-27 at 13:14:12ID: 24955500

Ah, sorry, YES the line at 141 is:
$vars = $vars + $item->query;

I think they are arrays [ ]

I have attached the whole router.php code to confirm..

Select all Open in new window

Now go back and read my comment #24935588 please. Specifically the last few lines dealing with running the debug code to make sure we have the right types.

The error you are seeing implies that + is NOT the appropriate way to join the values.

Saying "I think they are arrays [ ]" is where we started really.

Or, in other words, please follow our suggestions. They are normally little steps to avoid the wrong-path-rewind problems of big changes.

Ok,
I added in the lines of code you said just after the line of code in questions in router.php

//Only an Itemid ? Get the full information from the itemid
            if(count($this->getVars()) == 1)
            {
                  $item = $menu->getItem($this->getVar('Itemid'));
                  $vars = $vars + $item->query;
            }
var_dump($vars, $item->query);
die();

And when I tried to run the application I got:

array(0) { } NULL

by: RQuadlingPosted on 2009-07-28 at 14:57:29ID: 24965592

Right. So, $item->query is null. You cannot add null to an array.

<?php
$array = array();
$null = null;
$array = $array + $null;

results in ...

PHP Fatal error: Unsupported operand types ...

So it is now the case of going backwards from this point and see where the failure is.

Each of these needs to be run one at a time as the results may be long and complex.

var_dump($this->getVar('Itemid'));
var_dump($menu->getItem($this->getVar('Itemid')));

Make sure that 'Itemid' is correct and not say 'ItemID' or something different.

by: snowball77Posted on 2009-07-28 at 20:13:21ID: 24966913

Ok, sorry to be so ignorant with this, but can you explain the steps.

You say each of these need to be run one at a time.....what do you mean exactly?

by: RQuadlingPosted on 2009-07-29 at 04:33:23ID: 24969088

Put the first var_dump() in your code (replacing the one you've already got) and then run it. What is the result. Then replace that with the next, run it, record result.

Step by step.

We know that the point of failure is currently at line 141 and that the value of $item->query is null and I think you think it should be something different.

The problem I see though is that Joomla is a significant project.

I see (http://www.joomla.org/announcements/release-news/5243-joomla-1513-security-release-now-available.html) that there is a security release available.

Are you able to upgrade and re-test? Make a note of anything you changed and see if it is still appropriate.

As for finding the issue, you need to track back from line 141 and see what values are not being processed correctly.

What customisations have you performed?

I am going to do an upgrade and retest

by: snowball77Posted on 2009-08-11 at 01:25:48ID: 25067001

I upgraded and it worked
