[solved]way to clear cache through Dragonfly :: Archived

bitwisehost

I thought it would be cool if there was a button in the administration side that would clear the cache directory.
The only way I know of is through cpanel or ftp

i second this idea Smile

I think personally I'd be more concerned about what common circumstance leads you to need to clear the cache on a regular basis and if it's better to address that root cause.

i can do allow you view and clear Cache Dir right on Admin Super Access?

ians.. creating themes.. working on porting modules, etc... they require clearing cache frequently

Exactly why I thought it would be cool to have.

ians

would it not be easier just to make your cache unwriteable for the duration of that testing? I'm surprised mod ports needs this, I wasn't aware many made much use of cache.

ians, Cache is help to speed up the site by reduce Queries but it take Queries into array

Ians, I would agree with having an option to clear cache on the admin area. It is tipically harder to test or work on a theme and having to clear cache dir often. Espescially having to login to FTP to just clearing cache (when you have to).

Let me ask you this. What is the purpose of Admin Menu (area)?

To be able to administer it, right? So why not have all the tools you need to work right there.

As there was a saying I heard before:

If you want to work harder, so be my guess. I rather work smarter. Wink

er...I have never cleared cache while making a theme. like ians said, you could just make it unwritable until you're done, that would be even easier than having to constantly clear in admin

If you're testing a theme though, you need to know that it will work properly in a normal environment.

Not everybody has to utilize the facility, if you don't want to use it then don't.

Several people do, that's why there's a request here Wink

Personally, I think this would be a handy option in the Admin Section, even if I didn't use it that frequently.

Ok I figured out how to do this! Someone let me know if you see any problems or a better way to do this...

in admin/links/adlnk_main.php around line 43 rem out the if statement like below

PHP:


//if (function_exists('mmcache') || function_exists('eaccelerator')) {
		$menuitems['_AMENU1']['Cache']['URL'] = adminlink('cache');
		$menuitems['_AMENU1']['Cache']['IMG'] = 'cache';
//}

Than I made changes to admin/modules/cache.php
Add this code just below line 26

PHP:

if ($mode == 'clear') {
	Cache::clear();
}

Add this code just below line 75

PHP:

if ($mode == 'clear') {
	echo '<center><font class="option"><strong>Cache Cleared</strong></font></center>';
}
echo '<center><font class="option"><strong><a href="'.adminlink('&amp;mode=clear').'">Click Here to Clear Cache</a></strong></font></center><br />';

Here is all of the cache.php code

I'm still having a hard time understanding the requirement for it. There's something about testing in a normal environment that would appear at odds with clearing the cache. So, it's unclear if this is supposed to be a testing tool or a development tool to me at least.

I have had issues in the past when I installed a new mod and it wouldn't work. I think if you do a search in the forums alot of issues are solved by clearing the cache.

The function to clear the cache is already built into the Cache class. I just added a link to the cache.php that calls it.
