I have a custom error page for 500 Server Errors in CakePHP 3.
My src\Template\Layout\error.ctp template file has been adjusted to have my default error template in it. And then I've also updated my view file at src\Template\Error\error500.ctp. I even added this line, $this->layout = 'error'; as described in the docs.
This is what my error view looks like:
<?php
use Cake\Core\Configure;
use Cake\Error\Debugger;
$this->layout = 'error';
$this->Html->addCrumb('Error');
?>
<section class="content">
<div class="error-page">
<h2 class="headline text-red">500</h2>
<div class="error-content">
<h3><i class="fa fa-warning text-red"></i> Oops! Something went wrong.</h3>
<p>
We will work on fixing that right away.
Meanwhile, you may return to dashboard or try using the search form.
</p>
</div>
</div>
</section>
However, it still shows the default CakePHP error page.
What am I missing?
Just turn off the debug in app.php like
'debug' => false
As it written in cookbook
Each framework layer exception has its own view file located in the core templates but you really don’t need to bother customizing them as they are used only during development. With debug turned off all framework layer exceptions are converted to InternalErrorException

i have looked at the documentatioin of cakephp 2.5.4 about custom flash messages and some other tutorials on how to make this but its not working
i have error.ctp and success.ctp under elements folder
error.ctp
<div id="error-flash">
<?php echo h($message); ?>
</div>
success.ctp
<div id="success-flash">
<?php echo h($message); ?>
</div>
and in controller i call them like this
$this->Session->setFlash(__(' file successfully uploaded.','success',array('class'=>"flash_msg_ok")));
$this->Session->setFlash(__('Upload Failed','error',
array("class" => "flash_msg_error")));
my chrome developer tools still shows the default flash generated.
its not rendering the element or applying the specified classes
i've also tried this
$this->Session->setFlash('success','default',array('class'=> 'success'))
still nothing.
of note is that am using custom layout and css for the page.
what am i missing here?
There are a couple of issues..
First, you've accidentally put the other function variables inside the translation string. You can fix the call as follows (note closing bracket moved to end of message string):
$this->Session->setFlash(__(' file successfully uploaded.'),'success',array('class'=>"flash_msg_ok"));
$this->Session->setFlash(__('Upload Failed'),'error',
array("class" => "flash_msg_error"));
Second, you'll need to add the class to your custom error element file (the cakephp docs neglect to mention this!). For example:
<div id="error-flash" class="<?php echo $class; ?>">
<?php echo h($message); ?>
</div>
Hope that helps!
I have been developing a website in CakePHP 2.5.6 and have suddenly had an issue where when using $this->Html->Image(''); the image wont display on the page and I get this error if I go to the Image URL Directly:
Missing Controller
Error: ImgController could not be found.
Error: Create the class ImgController below in file: app/Controller/ImgController.php
<?php
class ImgController extends AppController {
}
Notice: If you want to customize this error message, create app/View/Errors/missing_controller.ctp
As I haven't been using CakePHP for long im not sure where to start with resolving this, its never done this before to me.
Any help would be appreciated,
Steve
EDIT:
The example I have been using is this:
<?php echo $this->Html->image('cake.power.gif');?>
it returns the following:
<img src="/trunk/img/cake.power.gif" alt="" />
I have checked and the image does exist on my server in the directory app/webroot/img/cake.power.gif
I am using CakePHP 2.3
I have two environments where I have my web application. At the testing environment with the exact same version of the application (all files are the same) I am having a problem with the Form->postLink method.
It shows this error on the Javascript console:
Uncaught TypeError: Object # has no method 'submit' users:119
onclick
Comparing the resulting HTML from both environments I can notice that the attributes name and id generated by this method are repeated more than once in the same page (which shouldn't be like that).
This is the code use to generate those post links:
foreach($users as $user){
$delete = $this->Form->postLink(__('Delete'), array('action' => 'delete', $user['user_id']), __('Are you sure you want to delete %s?', $user['user_id']));
}
This is the problematic generated HTML with repeated values for id and name as you can see:
<!-- link 1 -->
<form action="delete/1/" name="post_51e8019d095f1" id="post_51e8019d095f1" style="display:none;" method="post">
<input type="hidden" name="_method" value="POST"/>
</form>
Delete
<!-- link 2 -->
<form action="delete/2/" name="post_51e8019d095f1" id="post_51e8019d095f1" style="display:none;" method="post">
<input type="hidden" name="_method" value="POST"/>
</form>
Delete
Why is this happening?
Could it be related with the configuration of the web server somehow? I don't see another explanation for it...
Thanks.
The problem was caused by a bug in IIS 7.0.6000.16386 and the PHP function uniqid as pointed out here.
I am using a slightly different version in both environments ( IIS 7.0.6000.16386 vs IIS 7.5.7600.16385) and that was the cause of the problem.
In order to solve it I modified the file lib/Cake/View/Helper/FormHelper.php chaning the line $formName = uniqid('post_'); inside the postLink function to:
$formName = uniqid('post_', true);
That adds more entropy and as the documentation says:
If set to TRUE, uniqid() will add additional entropy (using the combined linear congruential generator) at the end of the return value, which increases the likelihood that the result will be unique.
Update
Ended up having to add one more change due to problems with javascript in forms.
I added one more line after $formName = uniqid('post_', true); so it looks like:
$formName = uniqid('post_', true);
$formName = str_replace('.', '', $formName);
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.
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!
