AndreD Posted April 2, 2014 Share Posted April 2, 2014 I am looking to disallow or block the string "http://" from the message box of a PHP form. I don't need an error message as it is purely to block spam that is flooding a clients site. Below is the code for the message section. I am really hoping for a simple fix to add to the existing code. <div id="row"><div id="input"><textarea id="comment" name="comment" class="mess" placeholder="Type your work description here." scrolling="no"><?php echo isset($_POST['comment'])? $_POST['comment'] : ''; ?></textarea><?php if(in_array('comment', $validation)): ?><span class="error"><?php echo $error_messages['comment']; ?></span><?php endif; ?></div><!-- end .input --></div><!-- end .row --> Link to comment https://forums.phpfreaks.com/topic/287466-block-or-dissallow-http-string-in-contact-form-message-box/ Share on other sites More sharing options...

cyberRobot Posted April 2, 2014 Share Posted April 2, 2014 You don't think your normal customers would ever type a website address? For example, would the form ever be used to report a broken link on the website? As for what you could use to see if a message contains a certain string, you could try strpos() or preg_match().

AndreD Posted April 2, 2014 Author Share Posted April 2, 2014 Captcha isn't an option as the client doesn't want it. As far as broken links no, its a small Paving site that I maintain SEO on as well so I review the site weekly anyway. I will look into both strpos() and preg_match() suggestions as well.
