require form fields

mallen · October 15, 2008

I have a simple form that has name, email and file to send. I removed the requirements for the file. Why does it still not send until you enter a file to send?

<?php
ini_set('display_errors', 1);

   $missing = array();

   // get the sender's name and email address
   // we'll just plug them a variable to be used later
   $from = stripslashes($_POST['fromname'])."<".stripslashes($_POST['fromemail']).">";

   // generate a random string to be used as the boundary marker
   $mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";

//}  //<----- REMOVE

I don't see the comment line in my code. If I remove the } I get an error.

dragonqueen · October 16, 2008

I think they meant here:

//if (file_exists($tmp_name)){ //<--- REMOVE

You should only have the // in front of comments not the codes you want processed. It should look like:

if (file_exists($tmp_name)){

mallen · October 16, 2008

I figured out what line he was showing me to remove. I did that. Now if you leave the file field blank it displays

"Invalid file type! Only gif, jpg, pdf and DWG files are allowed to be uploaded. Please Complete the missing items"

I want it to send the form and not display anything if you leave that field empty.
