Daney11 Posted December 5, 2007 Share Posted December 5, 2007 Hey guys, Im using this if (eregi ('^[[:alpha:]\.\'\-]{2,15}$', stripslashes(trim($_POST['member_firstname'])))) { However, users are allowed to enter as many spaces as they want, example " Da N e" I want it so that the user can only enter one space in the form, how would i go about doing this? Thanks Link to comment https://forums.phpfreaks.com/topic/80278-eregi/ Share on other sites More sharing options...
Daney11 Posted December 5, 2007 Author Share Posted December 5, 2007 and also, to limit it to letters and numbers only? [a-z0-9A-Z] ? Link to comment https://forums.phpfreaks.com/topic/80278-eregi/#findComment-406874 Share on other sites More sharing options...
magic2goodil Posted December 5, 2007 Share Posted December 5, 2007 You might try something on the actual form page in javascript instead. Something like: <html> <head> <script> var spaces = 0; var theID; function watchKeys(e,id) { theID = id; if(window.event) { // IE key = e.keyCode; } else if(e.which) { // Netscape/Firefox/Opera key = e.which; } if(key == 32) { //spacebar if(spaces == 1) { val = document.getElementById(theID).value; document.getElementById(theID).value = val.substring(0, val.length-1); } else { spaces++; } } } </script> </head> <body> <input type="text" id="myText" name="myText" onkeypress="return watchKeys(event,this.id);"> </body> </html> I tested this a bit after I made it, it's buggy, but it's a start for you if you want to go that route.

Thanks try this... preg_match_all('/\s/', $string, $matches, PREG_OFFSET_CAPTURE, 3); if(!preg_match("|^[a-z0-9]$|i",$string)||count($matches)>1){ print "You have exeeded 1 space, or your string is not alpha-numerical."; } Link to comment https://forums.phpfreaks.com/topic/80278-eregi/#findComment-406890 Share on other sites More sharing options...
