REGEX CHECK WORDPRESS TAGS

posted by Subzero on 2009-07-22 14:41:13
Hi, sorry for my bad english, my question is:
i riceve a tags from post: $tags = $_POST['tags']; //Es: gossip, culture, internet, (the tags of wordpress)
and I would find them with the regex, but that should not exceed 7 words, that is, for example tags1, tags2, tags3, tags4, tags5, tags6, tags7 and stop, if there is tags7 I must leave an error.
my code is:
	$tags = $_POST['tags'];
        if( !preg_match( "/([a-zA-Z0-9\-\_ ]+,){1,7}/s", $tags)){
          echo('<noscript>Errore: Tags non validi oppure maggiori di 7!</noscript><script language="JavaScript">alert("Errore: Tags non validi oppure maggiori di 7!");location.href=\'<a href="http://www.mysite.it\';" rel="nofollow" target="_blank">http://www.mysite.it\';</a></script>');
          die();
        } else {
           $tags = htmlspecialchars($_POST['tags']);
        }
but when I surpass even one tags me it onto the same ...
Thanks

Hello,
Why do you want to use regex? You could use explode(), example:
 
$tags = $_POST['tags'];
 
if (count(explode("," $tags, 8))>7){
    echo('<noscript>Errore: Tags non validi oppure maggiori di 7!</noscript><script language="JavaScript">alert("Errore: Tags non validi oppure maggiori di 7!");location.href=\'<a href="<a href="http://www.mysite.it\';"" rel="nofollow" target="_blank">http://www.mysite.it\';"</a> rel="nofollow" target="_blank"><a href="http://www.mysite.it\';" rel="nofollow" target="_blank">http://www.mysite.it\';</a></a></script>');
    exit();
}
else
    $tags = htmlspecialchars($tags);
 
Tell me if it's good for you!
Bye

Ops sorry, I forgot a comma:
 
if (count(explode(",", $tags, 8))>7){
....
}
 
If you have any other problem, create a new question.
