How to clear the cache in Typo3 from an external s

Question

I do have a PHP script, which is not an extension for Typo3. Now I would like to delete the whole Cache of Typo3 out of this script. How is that possible?

Answer 1

in typo3 6.x extbase its simple.

Edit : clearPageCache is not static then you need to create object of CacheService

TYPO3\CMS\Extbase\Service\CacheService::clearPageCache(pageUid);

Answer 2

TYPO3 6.x

first initialize the Service in your Class

/**
 * @var Tx_Extbase_Service_CacheService
 */
protected $cacheService;

/**
 * @param Tx_Extbase_Service_CacheService $cacheService
 * @return void
 */
public function injectCacheService(Tx_Extbase_Service_CacheService $cacheService) {
    $this->cacheService = $cacheService;
}

in your function just call

$this->cacheService->clearPageCache($pids);

while $pids is an integer (for single page) or array of integers (multiple pages)

see: http://typo3.org/api/typo3cms/class_t_y_p_o3_1_1_c_m_s_1_1_extbase_1_1_service_1_1_cache_service.html

In TYPO3 since 4.5 (I think) its a static method so you have just to call

Tx_Extbase_Utility_Cache::clearPageCache($pids);

in your controller.

Found it here: http://www.phpkode.com/source/p/typo-cms/typo3_src+dummy-4.6.5/typo3/sysext/extbase/Classes/MVC/Controller/ActionController.php

UPDATE

From TYPO3 7 on you can also install Helmut Hummels Extension typo3_console. Then you can clear the cache like:

typo3cms cache:flush

Answer 3

I found the solution myself and its actually pretty easy. I took a look into the class.t3lib_tcemain.php in the t3lib folder. There you've got the necessary commands to clear the cache. It also checks, if you have the cachingframework enabled. If so, you need to truncate a few other tables as well (Starts with cachingframework_cache_)

It is basically:

<?php

 require_once('./typo3conf/localconf.php');

 $conn = mysql_connect($typo_db_host, $typo_db_username, $typo_db_password);
 mysql_select_db($typo_db);

 // Clear Cache here
 mysql_query("TRUNCATE cache_treelist;");
 mysql_query("TRUNCATE cache_pagesection;");
 mysql_query("TRUNCATE cache_hash;");
 mysql_query("TRUNCATE cache_pages;");
 if($handle = opendir('./typo3conf')) {
    while (false !== ($file = readdir($handle))) {
        if(strpos($file, 'temp_CACHED_')!==false) {
            unlink('./typo3conf/'.$file);
        }
    }
    closedir($handle);
 }

?>

In FLOW3 there is a possibility to do such stuff, as far as I know with TYPO3 v.4.x You have no such default CLI option, so You should use or You own script, or use such extensions as cleartypo3cache or Cli Cleaner.

Also I made a bash script to clean cache tables of Your dB : https://gist.github.com/fedir/5162747

Answer 5

For removing all the cache form TYPO3,

You have to TRUNCATE database tables that contains cache data. They are : cache_treelist cache_pagesection cache_hash cache_pages

Then you also have to empty 'typo3temp' folder to clear major cache from TYPO3. For that you can use external script like given in the below link.

Answer 6

1. install the TYPO3 Extension cleartypo3cache
2. create a tool and a keyboard shortcut in PhpStorm 4 to trigger cleartypo3cache
3. SSH access with passwordless pubkey authentication when pushing to a remote host.

Install Extension "cleartypo3cache" and create the BE user "_cli_cleartypo3cache" and add the following TSconfig:

options.clearCache.all=1
options.clearCache.pages=1

Now test if cache is cleared:

$ cd /path/tp/typo3-site/
$ php typo3/cli_dispatch.phpsh cleartypo3cache all

If your webserver is on localhost, you are lucky because you don't need this shell script. If your webserver is on a remote host, you need an additional wrapper script. This is because PhpStorm does not provide an environment variable for the remote host directory. You have to set this directory statically for each project in the wrapper script:

#!/bin/sh

TYPO3_SITE_PATH="/path/to/typo3-site"
USER="alice"
HOST="example.com"

/usr/bin/ssh $USER@$HOST '/usr/bin/php $TYPO3_SITE_PATH/typo3/cli_dispatch.phpsh cleartypo3cache all'

Save this file in your project file directory into .idea/clear-typo3-cache.sh and make it executable:

$ chmod 755 .idea/clear-typo3-cache.sh

PhpStorm External Tools You need to create an "external tool" in PhpStorm to be able to clear cache.

1. Go to PhpStorm-->Settings-->External Tools-->Add...
2. Give your tool a name and a group, e.g. "Deployment" -> "Clear TYPO3 Cache"
3. Deactivate checkbox "Open Console" and "Menu->Search Results"

Remote host scenario

Add the following line to "Programm:"

$ProjectFileDir$/.idea/clear-typo3-cache.sh

Localhost scenario

Add this line to "Program:"

$PhpExecutable$

Add this line to "Parameters:"

$ProjectFileDir$/typo3/cli_dispatch.phpsh cleartypo3cache all

You need to have a PHP interpreter configured in PhpStorm-->Settings-->PHP to use $PhpExecutable$. Alternatively you can use /usr/bin/php http://www.t3node.com/fileadmin/user_upload/images/phpstorm-external-tools-typo3-cache.png

PhpStorm Keymap I suggest to use the same key binding as you use for saving or remote host uploading:

Go to PhpStorm-->Settings-->Keymap

For remote host scenario, navigate to: Main menu-->Tools-->Deployment-->Upload to Default Server. Notice the existing shortcut. If you don't have one for that, create a new one (I use ALT+SHIFT+U) For the localhost scenario, just use Ctrl+S (Main menu-->File-->Save All).

1. Now navigate to the External Tool you have created (e.g. External Tools-->Deployment->Clear TYPO3 Cache)
2. Right click "Add Keyboard Shortcut"
3. Create the particular shortcut in "First Stroke"

Now PhpStorm will warn you that the shortcut is already in use for a different command. That's fine, it's exactly what we want to have.

That's it. Your TYPO3 caches are always cleared when you hit save or upload on your keyboard.
