First off, thanks a lot for your help. I think I'm a lot closer now. I just tried this code, and it seems to work fine, except for one problem: When the form is first displayed, it gives the blank fields error: [i]You didn't fill in one or more required fields. You must enter: First Name Last Name Phone[/i] After that it works fine. How can I ensure that the form understands not to display blank field notices when it is first loaded? Thanks again...

Hello, I am relatively new to php/mysql and have been trying to get the following code to work, without success for about a week. Please help a poor newbie. Here is my initial code: [code] <?php // checkBlank.php -- a program to check for blank entries in a form ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Empty Fields</title> </head> <body> <?php // set up array of label fields $label_array = array ( "first_name" => "First Name", "middle_name" => "Middle Name", "last_name" => "Last Name", "phone" => "Phone" ); // check each field for blanks foreach ($_POST as $field => $value) { if ($field != "middle_name") { if ( !$value ) { $blank_array[$field] = "blank"; } } } // if any fields are blank, display error message and form if (@sizeof($blank_array) > 0) // if blank fields are found { echo "<b>You didn't fill in one or more required fields. You must enter:</b>"; // display list of missing information foreach ($blank_array as $field => $value) { echo "<b><blockquote>$label_array[$field]</blockquote></b>"; } // end foreach loop // redisplay form $first_name=trim(strip_tags($_POST['first_name'])); $middle_name=trim(strip_tags($_POST['middle_name'])); $last_name=trim(strip_tags($_POST['last_name'])); $phone=trim(strip_tags($_POST['phone'])); echo "<p><hr> <form action='checkBlank.php' method='POST'> <center> <table width='95%' border='0' cellspacing='0' cellpadding='2'> <tr><td align='right'><b>{$label_array['first_name']}: </b></td> <td><input type='text' name='first_name' size='65' maxlength='65' value='$first_name' ></td> </tr> <tr><td align='right'><b>{$label_array['middle_name']}: </b></td> <td><input type='text' name='middle_name' size='65' maxlength='65' value='$middle_name' ></td> </tr> <tr><td align='right'><b>{$label_array['last_name']}: </b></td> <td><input type='text' name='last_name' size='65' maxlength='65' value='$last_name' ></td> </tr> <tr><td align='right'><b>{$label_array['phone']}: </b></td> <td><input type='text' name='phone' size='65' maxlength='65' value='$phone' ></td> </tr> </table> <p><input type='submit' value='Submit name and phone number' > </form> </center>"; exit(); } echo "Welcome to your new account. You may now <a href='login.php'>log in</a>."; ?> </body> </html> [/code] When I view this locally, I see: Welcome to your new account. Please log in. The form is completely bypassed. So, I tried moving the '}' after the exit(); (line 68) line to the line right before the \\redisplay form comments (line 37). When I do that, I get the form, and it works flawlessly, except when I finally input all the required fields, the form just continues to redisplay. It does not display the welcome message. In short, I can't get the form to display the welcome message upon successfully inputting all required fields. I'm guessing this is due to a missing ELSE statement or bracket, but I can't for the life of me figure out what I'm missing. Any help would be greatly appreciated.
