knobby2k Posted July 13, 2011 Share Posted July 13, 2011 Hi guys, got a bit of a problem! well not so much a problem but i'm a bit confused of what to do for the best. basically i am trying to do a preg_match to validate names being entered into an input field using the following code: if ( !preg_match("/^([a-z\-\' ])+$/i", $this->input[$field]) ) The only characters that i want to allow through are... a-z - ' however, it still will not allow me to enter a ' into the field and i think i know why... when i go to view source on the page it displays this: <p>*First Name: <input type="text" name="firstname" value="John'" maxlength="80" /> It's cleansing the data earlier on in the script here: $data[$key] = trim(htmlspecialchars(strip_tags(stripslashes($value)), ENT_QUOTES, 'UTF-8')); so converting the apostrophe to '''. Obviously with me then doing a preg_match it is refusing the '&#;'. Now my question is... A) do i allow for '&#;' in the preg_match OR B) remove the htmlspecialchars any suggestions? cheers Quote Link to comment Share on other sites More sharing options...
wildteen88 Posted July 13, 2011 Share Posted July 13, 2011 I'd just apply htmlentities once the username has been validated/verified. Quote Link to comment Share on other sites More sharing options...
knobby2k Posted July 13, 2011 Author Share Posted July 13, 2011 I'd just apply htmlentities once the username has been validated/verified. so pass through preg_match to validate that the data is what i expect/require then run that variable through htmlentities? thanks Quote Link to comment Share on other sites More sharing options...

Double posting will ultimately waste peoples' time. Quote Link to comment Share on other sites More sharing options...
