Flipperbw Posted September 16, 2010 Share Posted September 16, 2010 The Issue (note: sorry for double post in the regex forum.) My users can post comments. I want to turn the hidden links within those comments into clickable URLs. I have the following function to do this: if (!function_exists('create_link')) { function create_link($url) { $pattern = "#((http|https|ftp)://(\S*?\.\S*?))(\s|\;|\)|\]|\[|\{|\}|,|\"|'|:|\<|$|\.\s)#ie"; $link_title = character_limiter(preg_replace($pattern, "$3", $url), 50); $link = preg_replace($pattern, "'<a href=\"$1\" target=\"_blank\">{LINK_TITLE}</a>$4'", $url); if ($link == $url) { $url = 'http://' . $url; $link = preg_replace($pattern, "'<a href=\"$1\" target=\"_blank\">{LINK_TITLE}</a>$4'", $url); } if ($link != $url) { $result = str_replace('{LINK_TITLE}', $link_title, $link); } else { $result = FALSE; } return $result; } } I know that the regex is pretty bad. It kind of works, but makes every single thing with a period into a link, and messes up sometimes with target= portion where it will actually display that. I've tried a bunch of other regex's but every single one gives me problems, typically like "php unknown modifier ]" or ")" or something. here's how I call this function when users hit submit in the comment field: $words = preg_split("/[\s,]+/", $comment); foreach ($words as $word) { if ($link = create_link($word)) { $comment = str_replace($word, $link, $comment); I just want to convert the right links into links. is something like: ^(((ht|f)tp(s?))\://)?(www.|[a-zA-Z].)[a-zA-Z0-9\-\.]+\.(com|edu|gov|mil|net|org|biz|info|name|museum|us|ca|uk)(\:[0-9]+)*(/($|[a-zA-Z0-9\.\,\;\?\'\\\+&%\$#\=~_\-]+))*$ any better? I don't know, nothing seems to work. Quote Link to comment Share on other sites More sharing options...
