SilentQ-noob- Posted July 18, 2007 Share Posted July 18, 2007 Does anybody know how to make the PHP code for and if statement using strlen, where, if a field in a form isnt filled out an error message appears. so if the name field is empty it gives an error message. if (strlen($_POST['name'] <= 1 )) { echo "The Name field has not been filled out, or is too short"; include ("_form.php"); } else { echo " thanks for filling out our form" ; } this is what I have, doesnt work though....any help would be appreciated! thanks, -noob- Link to comment https://forums.phpfreaks.com/topic/60666-solved-strlen-help/ Share on other sites More sharing options...

SilentQ-noob- Posted July 18, 2007 Author Share Posted July 18, 2007 still when I add that, and put something into the name field, it returns "The Name field has not been filled out, or is too short" Link to comment https://forums.phpfreaks.com/topic/60666-solved-strlen-help/#findComment-301816 Share on other sites More sharing options...
trq Posted July 18, 2007 Share Posted July 18, 2007 Sorry... must be half asleep. if (strlen($_POST['name']) <= 1 ) { Link to comment https://forums.phpfreaks.com/topic/60666-solved-strlen-help/#findComment-301818 Share on other sites More sharing options...
SilentQ-noob- Posted July 18, 2007 Author Share Posted July 18, 2007 if (strlen($_POST['name']) <= 1 ) { Thanks, but I've tried changing it to this, but that isnt the problem. The way I wrote it seems to be the correct syntax- (the way you suggested causes an error). So I really dont know why it returns true, regardless of wheather I put something into the name field or not.

trq Posted July 18, 2007 Share Posted July 18, 2007 The way I wrote it seems to be the correct syntax Well its not. strlen expects 1 string, not an expression. the way you suggested causes an error What error?
