Hi,
i'm french, i'm using regular expressions in php in order to rewrite
hyperlink tags in a specific way before apache output is beeing sent to
client.
Purpose is to replace href attribute of any A html tag by a javascript
function calling an ajax loader.
Currently I have wrote that:
$pattern = '/<a
href="(http:\/\/dev.netdoor.fr|(\.))\/index.php\?page=(.*?)">(.*?)<\\/a>/i';
$replacement = '<a href="javascript:void(0);"
OnClick="javascript:yui_fastLoader(\'./systeme/chargeur.php?page=$4\');">$5</a>';
$html_mark = preg_replace($pattern, $replacement, $html_mark);
it works, but it's too permissive, it replaces too much links (some
links with some get parameters must stay unchanged)
I don't really understand my pattern...it's a little strange for me...lol
I wouldn't like to rewrite links that contains any of the following
words in get parameters (query string):
noLoader
noLeftCol
skipallbutpage
skipservice
i would like to rewrite only link that begin with
'http://dev.netdoor.fr' or '.'
examples:
<a
href="http://dev.netdoor.fr/index.php?page=./comptes/index.php&noLoader&noLeftCol&idx=6&bdx=423&skipservice";>test</a>
=>must be not rewritted!
<a class="myclass"
href="./index.php?page=./comptes/mediatheque/index.php&filter=mov;flv;mpeg&idx=7">name</a>
=>must be rewritted like this :
<a class="myclass" href="javascript:void(0);"
OnClick="javascript:yui_fastLoader(\'./systeme/chargeur.php?page=./comptes/mediatheque/index.php&filter=mov;flv;mpeg&idx=7\');">name</a>
Please help me...:0)
best regards

It's complicated. I'd resort to using a callback. Even if it's possible
with just patterns, it wouldn't be very readable! Something like this:
if (!function_exists('make_replacement')) {
function make_replacement($m) {
$n=$m[2];
if (preg_match('~^(http://dev.netdoor.fr|\.)/index\.php\?(.*?)$~',
$n,$mm)) {
if (!preg_match('~noLoader|noLeftCol|skipallbutpage|skipservice~',
$mm[2])) {
$n='javascript:void(0);" '.
'OnClick="javascript:yui_fastLoader(\'./systeme/chargeur.php?'.
$mm[2].'\')';
}
}
return $m[1].'href="'.$n.'"'.$m[3];
}
}
$pat='~(<a.*?\s)href="(.*?)"(.*?>)~i';
$html_mark=preg_replace_callback($pat,'make_replacement',$html_mark);
