 |
|
Hei.
I want to have more compact cache files. They contain many whitespaces => more memory.
I have this code that is not working right:
| Code: | function smarty_prefilter_pre($output, &$smarty)
{
$output = str_replace(
array("\t", "\n")
, '', $tpl_output);
$output = preg_replace('/class=[\'"][ ]*(\w*)[ ]*[\'"]/', 'class=$1', $output);
$output = preg_replace('/class=[\'"][\'"]/', '', $output);
return $output;
} |
and:
$this->_smarty->loadFilter('pre','pre');
echo smarty_prefilter_pre($this->_smarty->fetch($tpl, $cache_id));
If I do something like
| Code: | function smarty_prefilter_pre($output, &$smarty)
{
echo $output;
return $output;
} |
No output is displayed.
Thanks!

| Code: | function smarty_prefilter_pre($output, &$smarty) {
$output = str_replace(… $tpl_output); |
"$output" !== "$tpl_output"
You should also note that you are stripping all kinds of whitespace you might not really want to strip. Have a look at outputfilter.trimwhitespace.php (in your plugins directory).

Yeah, that's wrong.
That's because of the fact that i copied and paste.
I edited my post, but my problem is still unsolved.
I need an output cache-filter if you could understand me. I also want to gzip the files cached, with a function that I want to create and add to this output cache-filter.
Do you falllow me?
PS: Thanks for the plugin name.

Note that prefilter run before a template gets compiled it does not help at all for your case.
Use an output filter.
Why does outputfilter.trimwhitespace.php not do the job?
Filters which are loaded exceute automatically.

is sort of nonesense.
Just try
| Code: |
$this->_smarty->loadFilter('output','trimwhitespace');
$this->_smarty->display($tpl, $cache_id);
