 Posted: Wed Sep 24, 2003 10:56 pm Post subject: Wordlist block |
 |
|
There I was, with a nice wordlist and a FAQ page. I needed some way to link certain words and phrases to a wordlist page, so I came up with this plug in. Hope someone finds it useful.. Input wanted.
| Code: | <?php
/*
* Smarty plugin
* -------------------------------------------------------------
* File: block.wordlist.php
* Type: block
* Name: wordlist
* Purpose: rewrite block and add links to wordlist page
* Parameters: wordlist [required] - array ("id" => "word") oderd by longest word
* href [required] - href string
* attr [optional] - attributes to <a>-tag
* assign [optional] - variable to collect output
* Author: Urban Jonsson <urban@solace.mh.se>
* -------------------------------------------------------------
* example
* {wordlist href="wordlist.php?id=%id" wordlist=$wordlist attr="class=faq target=_blank"}
* {$text}
* {/wordlist}
*/
function smarty_block_wordlist($params, $content, &$this)
{
extract($params);
if ( $wordlist && $content && $href) {
foreach ( $wordlist as $key => $val ) {
if ( ereg($val, $content) ) {
if ( substr(strtolower($content), (strpos(strtolower($content), strtolower($val))+strlen($val)), 4) != "</a>" ) {
$content = eregi_replace("$val", "<a $attr href=\"$href\">\\0</a>", $content);
$content = ereg_replace("%id", "$key", $content);
}
}
}
if (!empty($params['assign'])) {
$this->assign($params['assign'], $content);
} else {
echo $content;
}
}
}
?>
