Hello everyone.

I am building a system with various forums, and each forum has a number of members. I got a file, named members.php, to show members in each forum.

I used
Code:
$tpl->display('members.html', $cache_id);

to output the page. The $cache_id is a combination of forum id, $_GET['fid'], and current page number, $_GET['page'].

My goal is to delete cache files (all pages) when a new member joins, so that a new members list will be pulled from database, then a new cache file will be generated in the next visit.

I don't know how to achieve this, the best I could find is using cache group. I am wondering if I shall store the $cache_id like this,
Code:
$cache_id = $_GET['fid'] . "|" . $_GET['page'];


I was testing on Windows, when the php engine ran the code, it returned the following errors,

Warning: rename(F:\wamp\www\Tpl\_Compile\wrtE131.tmp,./Tpl/_Compile/1|1^47aa54bb39f6e5fd67ad0a1fe8a321b5d5e8ec64.file.Members.html.cache.php) [function.rename]: The filename, directory name, or volume label syntax is incorrect. (code: 123) in F:\wamp\www\Common\Class\sysplugins\smarty_internal_write_file.php on line 48

Warning: chmod() [function.chmod]: No such file or directory in F:\wamp\www\Common\Class\sysplugins\smarty_internal_write_file.php on line 50

I realized that Windows wouldn't allow "|" symbol in its filename. Is this an issue?


Lastly about deleting cache files, the documentation says when I delete cache files from cache group, I should leave the first param, template name, blank. I don't know why how smarty finds the right file.

Please help me out. Thank you very much.

Hi,

have a look at the file path:
Code:
F:\wamp\www\Tpl\_Compile\wrtE131.tmp,./Tpl/_Compile/1|1^47aa54bb39f6e5fd67ad0a1fe8a321b5d5e8ec64.file.Members.html.cache.php


the directroty name \wrtE131.tmp,./ seems not be ok. Maybe a typo i your filepath...

Regards, Chris

Hello Chris,
The error code was generated by Apache, I just copied it.

actually it was generated by PHP. But that's beside the point. Which Version are you using and have you run Smarty::testInstall()?

looking at your filepaths, you may want to enable subdirs: $smary->use_sub_dirs = true;

Thanks for you reply.

The version I am using is 3.0.8. I guess that is a stable release.

And I have run testInstall(), all directories were tested OK.

After I turned on use_sub_dirs, it seems that a new warning appeared before the two.

Thanks again.

… and what would that warning be?
what's your smarty setup? (just copy your code…)

I've figured out the problem. It was because the new class that extends from the original Smarty class.

Thanks for your help. Very Happy
