Input of email and url to be clickable

Question

I have a form that I process in PHP. Users sometimes put their email address in the form or URLs. These usually come out as text after I strip the input of tags.

Answer 1

you have to wrap the url in a anchor tag:

assuming $myLink is the link text coming from your db:

<a href="<?php echo $myLink; ?>"><?php echo $myLink; ?></a>

Answer 2

You can use a regular expression based function like this

function  autolink($message) { 
    //Convert all urls to links
    $message = preg_replace('#([\s|^])(www)#i', '$1http://$2', $message);
    $pattern = '#((http|https|ftp|telnet|news|gopher|file|wais):\/\/[^\s]+)#i';
    $replacement = '<a href="$1" target="_blank">$1</a>';
    $message = preg_replace($pattern, $replacement, $message);

    /* Convert all E-mail matches to appropriate HTML links */
    $pattern = '#([0-9a-z]([-_.]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.';
    $pattern .= '[a-wyz][a-z](fo|g|l|m|mes|o|op|pa|ro|seum|t|u|v|z)?)#i';
    $replacement = '<a href="mailto:\\1">\\1</a>';
    $message = preg_replace($pattern, $replacement, $message);
    return $message;
