i'm having a little problem with Zend Framework Full Page Cache.
My current Bootstrap configuration looks like this:
$dir = PUBLIC_PATH . "/tmp/";
$frontendOptions = array(
'lifetime' => 6000000000,
'content_type_memorization' => true,
'default_options' => array(
'cache_with_get_variables' => true,
'cache_with_post_variables' => true,
'cache_with_session_variables' => true,
'cache_with_cookie_variables' => true,
),
'regexps' => array(
'^/.*' => array('cache' => true),
)
);
$backendOptions = array(
'cache_dir' => $dir
);
// getting a Zend_Cache_Frontend_Page object
$cache = Zend_Cache::factory('Page',
'File',
$frontendOptions,
$backendOptions);
$cache->start();
which worked perfectly before changing our development system to the live one.
Now if we enable the caching system it creates the correct cached file in the correct path but doens't load it.
So for every request another cache file is created but the old one NEVER gets loaded.
Maybe anyone has had this problems before and can give me a hint?
Thanks in advance!
there might be issue with permission to move from development environment to live.
The tmp directory is writable by myself and other users of the same group and also apparently Zend will access the files as another user. The solution was to chmod 777 on the folder, making it writable.
let me know if i can help you more.

I am working with files in a drupal module. I added this form
$form['Background_image'] = array(
'#type' => 'managed_file',
'#title' => t('Image'),
'#progress_message' => t('Please wait...'),
'#progress_indicator' => 'bar',
'#description' => t('Click "Browse..." to select an image to upload.'),
'#required' => TRUE,
'#upload_validators' => array('file_validate_extensions' => array('jpeg jpg png gif')),
'#upload_location' => 'public://backgroundimage/',
'#default_value' => $this->options['Background_image'],
);
the file is added properly, once the file is uploaded a remove button appears allwoing to remove the file and upload a new one.The problem is that this button is not working so I looked into file module and I found that the hook of removing a file is not implemented yet.
function file_file_delete($file) {
// TODO: Remove references to a file that is in-use.
}
How can I remove an uploade file?
you should use file_delete()

I will be able to help you more if you post here module version,
maybe it will start working after update :-)
I just tried to use Zend_Cache in my application, and it worked. The problem now is I am not sure where to put Zend_Cache clean() method in my code.
Here is my code:
// application/Bootstrap.php
protected function _initCache()
{
$dir = "./cache";
$frontendOptions = array(
'lifetime' => 10,
'content_type_memorization' => true,
'default_options' => array(
'cache' => true,
'cache_with_get_variables' => true,
'cache_with_post_variables' => true,
'cache_with_session_variables' => true,
'cache_with_cookie_variables' => true,
),
'regexps' => array(
// cache the whole IndexController
'^/.*' => array('cache' => true),
'^/index/' => array('cache' => true),
// place more controller links here to cache them
)
);
$backendOptions = array(
'cache_dir' =>$dir
);
// getting a Zend_Cache_Frontend_Page object
$cache = Zend_Cache::factory('Page',
'File',
$frontendOptions,
$backendOptions);
$cache->start();
}
Where should I put the $cache->clean(/* something */);?
As you have configured our $frontend array to cache data for 10 seconds, so the data cached will automatically be remove after 10 second.
i would suggest that you can increase your time like
one hour : 3600 or 2 hours like 7200
However if later in your application you want to clean the entire cached data manually, simply write
$cache->clean();
This will clean the entire cached data. However if you want to remove specific data being cached, write
$cache->remove(‘mydata’);
for more use of cache see link
i am not associate with above link it is just for your knowledge
hope this will sure help you.
I am trying to cache everything that is output by layout script and controller's action script using Zend_Cache but it is not working correctly. All I get is
DEBUG HEADER : This is a cached page !
I got layout.phtml script and index.phtml script. Both produce html code.
In my IndexController i put
$frontendOptions = array(
'lifetime' => 7,
'debug_header' => true,
'regexps' => array(
'^/$' => array('cache' => true),
'^/index/' => array('cache' => true)
)
);
$backendOptions = array('cache_dir' => '../application/cache/');
$cache = Zend_Cache::factory('Page', 'File', $frontendOptions, $backendOptions);
if(!$cache->start('mypage')) {
}
How to get it working? I expect that html code should be saved in cache folder.
check this tutorial out Brandon Savage on Zend Cache, it's short and I think it's more current then the ZF docs.
I am trying to fiddle around with Zend_Cache, so I added following code to my action (will be moved to bootstrap later, I guess):
$frontendOptions = array(
'lifetime' => 7200,
'debug_header' => true, // für das Debuggen
'default_options' => array(
'cache' => true,
'cache_with_get_variables' => true,
'cache_with_session_variables' => true,
'cache_with_cookie_variables' => true,
'cache_with_post_variables' => true,
)
);
$backendOptions = array(
'cache_dir' => '/tmp/'
);
$cache = Zend_Cache::factory('Page', 'File',
$frontendOptions, $backendOptions
);
echo "hej";
var_dump($cache->start('someid'));
Zend generates a cache file containing hejbool(false) now, but apart from that it does not cache my page. According to a German book about zend framework, false is correct when there is no cache available. true is only returned when a cache was found.
When I debugged within Zend_Cache_Frontend_Page.php directly, it went down to the bottom of the start()-method, meaning that nothing went wrong (id given) and no cache was found, so one had to be generated. This was done (I can see it in /tmp/), but without the needed content.
So why does not not cache the output from Zend_View, but only direct output via echo?
I do not call any explicit function to render the view, but this did not seem necessary anymore (my views are always rendered automatically according to controller and action). I tried it for both a standard XHTML template (index.phtml) and an RSS template (index.rss.phtml).
Any ideas? Do you need any other code fragments?
When using the Zend_Cache_Frontend_Page you have to enable the disableOutputBuffering option. The reason is that Zend_Cache_Frontend_Page uses ob_start with a callback and it has to be the first call to ob_start otherwise it leads to that strange behaviour you've encountered.
To enable it you can either set it in your Bootstrap with
Zend_Controller_Front::getInstance()->setParam('disableOutputBuffering', true);
or using the configuration file after your frontController-setup (here in the INI-style configuration):
resources.frontController.params.disableOutputBuffering = true
Ok, here's the problem:
$frontendOptions = array(
'lifetime' => 7200,
'debug_header' => true, // for debugging, but it doesn't work...
'regexps' => array(
// Cache the static pages
'^/pages/' => array('cache' => true),
)
);
$backendOptions = $config->cache->backOptions->toArray();
// getting a Zend_Cache_Frontend_Page object
require_once 'Zend/Cache.php';
$cache = Zend_Cache::factory('Page',
$config->cache->backend,
$frontendOptions,
$backendOptions);
$cache->start();
This doesn't do anything at all. Page loading times are exactly the same and the folder indicated in $backendOptions is empty. What am I doing wrong?
By the way: $config->cache->backend reads "file".
Well, following my tradition of answering my own questions, here comes the answer, and a subquestion, if anyone knows what's going on:
Basically, this thing doesn't work out of the box if you happen to run something more advanced than Hello World. I had a cookie set and since it found a cookie, it refused to do anything about it, so one hour digging in the caching code I discovered that the magic needed was simply to set
'cache_with_cookie_variables' => true,
And well, since all cookies are more or less unique and I don't really want to care about them, I set
'make_id_with_cookie_variables' => false
So now it works flawlessly.
Thanks to Chris and smoove for taking the time out and now in hindsight your comments made a lot of sense. Naturally though, I didn't have any errors or warnings and "File" was indeed spelled with uppercase.
What I wonder now is if I can send a spike to delete the proper cache file upon certain circumstances. I can hammer it (copy the ID generator in the cache and unset() the proper target), but there might be a fancier solution. If you have any idea, let me know.
Please go to config/application.ini and set:
resources.frontController.params.disableOutputBuffering = true
If you are done with config/application.ini , just copy and past the code below and have fun.
Please do remember the temporary file ; I have used here servercache you can use temp or tmp or whatsoever.
