 Posted: Fri Jul 13, 2007 2:47 pm Post subject: macro a prefilter for smarty text modules |
 |
|
I wrote a little macro-preprocessor. Maybe you can use it to save some typing or to avoid errors.
It would be nice if anybody can review the code. Especially the Regular expressions could take a second glance.
Have fun....
| Code: |
<?
/*****************************************************************
* A prefilter for makros in a smarty-template.
* @author = Stowasser Harald, Freinet GmBH, Germany. <stowasser@freinet.de>
* @date =12.07.2007
* @version 0.1
* @param string $tpl_source The template source code.
* @param Smarty &$smarty The Smarty wich has called this filter
*
* With this prefilter You can set macros in a smarty-Template.
* the macros will be replaced before the smarty-compiler does his work
* The Filter can allso handle macros with content.
* examples:
*
// This defines an output for your error
{set_macro error}
<b class="error">{$error}</b>
{/set_macro error}
// so this call:
{if $ding|has_error}{get_macro error}{/if}
// will be replaced to:
{if $ding|has_error}<b class="error">{$error}</b>{/if}
// The examlpe for my lable is a litle bit harder:
// The {$content}-Tag will be replaced with the text between {get_macro label} and {/get_macro label}
{set_macro label}
{if $form_last_element|is_required}
<label class="pflicht" for="{$form_last_element}">{$content}*</label>
{else}
<label class="normal" for="{$form_last_element}">{$content}</label>
{/if}
{/set_macro label}
{assign var='form_last_element' value='adr_forename'}
{get_macro label}Forename:{/get_macro label}
<input type="text" name="{$form_last_element}" value="{$adresse->getForename()}"/>
*/
function smarty_prefilter_macro($tpl_source, &$smarty) {
// Search for a set_macro-tag:
$macroset=array();
$pattern = "/[{] *set_macro .*?[}](.*?)[{] *\/ *set_macro ([\w]*)?.*?[}]/s";
$text=$tpl_source;
preg_match_all($pattern,$tpl_source,$macroset);
// And then delete it from the template:
$text= preg_replace("/[{] *set_macro .*?[}].*?[{] *\/ *set_macro .*?[}]/s","",$tpl_source);
// Now replace the get_macro-tags
if (count($macroset)==3){
$anz=count($macroset[2]);
for ($i=0;$i<$anz;$i++){
// is this a macro with content?
$content=array();
$macrotext=$macroset[1][$i];
$macro='get_macro '.$macroset[2][$i];
$pattern = "/[{] *".$macro.".*?[}](.*?)[{] *\/ *".$macro.".*?[}]/s";
preg_match_all($pattern,$text,$content);
if (count($content)>0){
// then replace the Content
$anz2=count($content[1]);
for ($j=0;$j<$anz2;$j++){
$neutext=preg_replace("/[{] *[$]content.*?[}]/",$content[1][$j],$macrotext);
$text =str_replace( $content[0][$j], $neutext, $text);
}
}
//If there is no closing tag just do a replace.
$text=preg_replace("/[{] *".$macro.".*?[}]/",$macroset[1][$i],$text);
}
}
return $text;
}

Version 0.3 is now online at incutio
Now you can define a File to include the macros. Thats good for a set of standard macros. |

There are lots of other ways to handle this too. Example:
| Code: | | {include file="macros.tpl" name="error} |
Then just have a template full of your macros.
Or, use config files to hold macros.
A prefilter is efficient though, it does the replacement once, at compile time. But if you ever changed a macro, you must remember to recompile. |
