in all my views i have a login/register (cake)form.
my question:
can i use the file cache engine with <cake:nocache>form</ cake:nocache>
1.) open url "www.domain.com/home"
2.) cachefile generated
3.) look perfect
4.) refresh (f5)
5.) error (when debug=1):
Parse error: parse error in C:\xampp\htdocs\cake_1.2.3.8166\app\tmp\cache\view \cake_1_2_3_8166_home.php on line 752
cachefile -> line 752 -> </html>
cakephp: 1.2.3.8166
example:
<cake:nocache>
<?
$user = $session->read("user");
if(!$user){ //$user true or false
echo "login:";
echo $form->create('AdminUser', array('action' =>'login_load'));
echo $form->input('email',array('label'=>false));
echo $form->input('password',array('label'=>false));
echo $form->submit('Login', array('id'=>'login'));
echo $form->end();
}else{
echo "hello user!";
}?>
</cake:nocache>
it's a cakephp bug. cake google groups
The dev state at https://trac.cakephp.org/ticket/6034 CakePHP does not support using the form helper from within tags at this time.

I am currently learning Cakephp and have made a profile page of which displays the username on it. You can only access this page when logged in so when you are on this page, I wish to display the username of the user in the HTML page title. This is also because your profile page is visible to other users.
At the moment to get the page headers I have used.
<title><?php echo $this->fetch('title'); ?> | Site Name</title>
<? $this->assign('title', 'Profile')?>
And to display the username on the page currently I have:
<?php echo $user['User']['user_name']; ?>
I have attempted to combine these two into something like shown below but clearly that's not working. Any ideas?
<? $this->assign('title', '<?php echo $user['User']['user_name']; ?>')?>
Thanks!
Mistake in the concatenation, change this in your .ctp
<? $this->assign('title', '<?php echo $user['User']['user_name']; ?>')?>
to this
<? $this->assign('title', $user['User']['user_name'])?>
Later on add this in your layout
<title><?php echo $this->fetch('title'); ?> | Site Name</title>
This will work :)
I've recently upgraded my 1.3 cake app to 2.0, and I'm trying to redo my app_error code.
With Cake 1.3, it was simply a case of creating an app_error.php file, putting it in my app root, and overriding the built-in error404() and missingController() actions.
Here is my old 1.3 /app/app_error.php file: http://pastebin.com/beWZD9PJ
It had some code that kicked in when someone arrived at the site with a predefined 'alias' URL, and then it redirected them accordingly.
I just need this to work in Cake2.0, and I see the manual is telling me its all changed, but I can't find a specific case like this. Can anyone help me out, so the error404 code kicks in?
Many thanks
4xx and 5xx errors in CakePHP 2.0 ar now exceptions, thus you need to customize your Exception renderer or handler. Read from this section to the bottom http://book.cakephp.org/2.0/en/development/exceptions.html#exception-renderer
You can throw a 404 exception with the following code in your controller in Cake 2:
throw new NotFoundException(__('Your error text here'));
Then, you just need to have APP/View/Errors/error400.ctp present with something relevant to display. Cake includes this by default:
<h2><?php echo $name; ?></h2>
<p class="error">
<strong><?php echo __d('cake', 'Error'); ?>: </strong>
<?php printf(
__d('cake', 'The requested address %s was not found on this server.'),
"<strong>'{$url}'</strong>"
); ?>
</p>
<?php
if (Configure::read('debug') > 0 ):
echo $this->element('exception_stack_trace');
endif;
?>
It's simple.
With cakephp 2, you have to add this function in your AppController:
public function appError($error) {
$this->redirect('/');
}
Here, for example we redirect all errors to index page.
On my PC with WAMP server and php 5.3.9 everything works fine.
When I upload it to server with php 5.2.1.7 all redirects stop working - when the ->redirect(..) is executed script stops working - it acts like there was die; instead of redirect and nothing is printed and redirect doesnt work.
These are redirects I am using:
$this->redirect( array('controller' => 'users', 'action' => 'login') );
$this->redirect( $this->referer() )
Both (in fact all...) stopped working after upload to server...
------ edit
I managed to show E_ALL errors and for example if I write $omg->lol() before redirect the error is reported as
Notice (8): Undefined variable: omg [APP/Controller/LanguagesController.php, line 31]
Fatal error: Call to a member function lol() on a non-object in ...
But still no error message for redirect...
I managed to fix it!
The problem was that few php files had some tabs or whitespaces before <?php tags and after ?> tags - when I deleted them everything works fine - damn PHP is real bitch!!!
Background: I'm new to CakePHP. I have a small test site (mostly composted of static views and a contact form at the moment) to play with while I learn. Everything worked fine on localhost (Apache on Ubuntu) so I deployed it to a shared hosting account (provided by Lunarpages). I moved the /cake folder out of the normal directory structure (so I could use it for multiple apps) and I reconfigured my webroot's index.php paths accordingly.
Problems:
setFlash messages do not get displayed. Even making a simple view that does nothing other than $this->Session->setFlash('message');. I don't get any error message, the flash just doesn't get displayed
Redirects don't work. For instance, after the contact form is completed I want to $this->redirect( array( 'action' => 'success' ), null, true); but the server throws an error:
Warning (2): Cannot modify header information - headers already sent by (output started at /routetoapp/config/routes.php:40) [CORE/cake/libs/controller/controller.php, line 742]
Everything else seems to work just as it did on localhost - URL rewriting, component loading, model validation. I don't know if my problems are related or separate issues
Troubleshooting so far:
I've tried both 'cake' and 'php' for Configure::write('Session.save', 'val'); but neither made a difference.
My app/tmp folder is writeable.
My layout template has the correct code for displaying flash messages. (The exact same M, V, C, and Layout objects display the expected flash on localhost)
I assume I'm missing something simple, but I'm new to this framework so I'm not sure where else to look.
See Matt Huggins answer for your flash problem. That's correct
As for your redirect issue,
you might have an extra space or something in your routes.php file. Make sure there are no spaces before the starting <?php tag and remove the closing ?>
$this->Session->setFlash(...) is used to SET the flash message from within the controller. When you're in the view, you should be rendering the flash message like this:
<?php $session->flash(); ?>
You can also make your flash message more elaborate if you need with something like this:
<?php if ($session->check('Message.flash')): ?>
<div class="message">
<?php $session->flash(); ?>
</div>
<?php endif; ?>
That was right but there also have echo add before $session->flash();
so, it should be like:
<?php if ($session->check('Message.flash')): ?>
<div class="message">
<?php echo $session->flash(); ?>
</div> <?php endif; ?>
this worked for me!
I am using cakePHP 1.26 and TinyMCE v3.38.
The .js file of the TinyMSC is stored under this directory:
http://www.mysite/js/tiny_mce/tiny_mce.js
In the page where the users can post new topic,
the URL of this page is like this:
http://www.mysite/user/newpost
Now I need to add the javascript to this page, and I have tried these:
echo $javascript->link('/js/tiny_mce/tiny_mce.js');
echo $javascript->link('js/tiny_mce/tiny_mce.js');
echo $javascript->link('../js/tiny_mce/tiny_mce.js');
But the tiny_mce.js can not be reached.
I believe that Cake already knows that your javascript is in /js/ through using the $javascript->link() structure in the first place - so try
echo $javascript->link('tiny_mce/tiny_mce.js');
and see if you get anywhere.
