[SOLVED] Required Fields in a Form

[betsy_ls]

I am trying to edit a form so that certain fields are required to submit.  I am very, very new to PHP though and am not sure how to do this.  The form already makes sure there is a valid email, but I also want the first name, last name and organization to be required.

 

Here is my PHP code.

 

 <?php





		if(isset($_POST['submitform']) && $_POST['submitform']==1) {



			if(isset($_POST['email']) && eregi("^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)@([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$", $_POST['email'])) {

				$to = "[email protected]";

				$subject = "GTT FORM SUBMISSION";

				$headers = "From: ".$_POST['email'];

				$date = date("r");

				$message = "Form submission sent from 'Subscribe' at ".$date."\n\n";



				$message .= "Salutation : ".$_POST['salutation']."\n";

				$message .= "First Name : ".$_POST['firstname']."\n";

				$message .= "Last Name : ".$_POST['lastname']."\n";

				$message .= "Company : ".$_POST['organization']."\n";

                                        $message .= "Title : ".$_POST['title']."\n\n";

                                        $message .= "Country : ".$_POST['country']."\n\n";

				$message .= "Phone : ".$_POST['phone']."\n";

				$message .= "Email : ".$_POST['email']."\n\n";



                                       if(isset($_POST['addtonetwork']) && $_POST['addtonetwork']=='yes') {

					$message .= "YES - Add to network.\n\n";

				} else {

					$message .= "NO - Do not add to network.\n\n";

				}







				if(mail($to, $subject, $message, $headers)) {



					include("includes/thankyou.php");

				} else {

					global $error;

					$error = "Mail could not be sent!";

					include("includes/form_subscribe.php");

				}

			} else {

				global $error;



				$error = "You must submit a valid E-Mail.";

				include("includes/form_subscribe.php");

			}



		} else {



			include("includes/form_subscribe.php");

		}

                 


            ?>

 

Please let me know if you need any other code.  I have been reading tutorials about this all day, but I do not know enough PHP to be able to apply it to the code I am editing.

 

Thanks!

many ways to do this.

 

this is how i would do it:

 

<?php

$valid_email = false;
$valid_first = false;
$valid_last  = false;
$valid_org = false;

$errors = array();

if(isset($_POST['submitform']) && $_POST['submitform']==1) {

if(isset($_POST['email']) && eregi("^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)@([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$", $_POST['email'])) {
	$valid_email = true;
} else {
	array_push($errors, "You must submit a valid E-Mail.");
}

if ($_POST['firstname'])!="") {
	$valid_first = true;
} else {
	array_push($errors, "You must enter your first name.");
}

if ($_POST['lastname'])!="") {
	$valid_last  = true;
} else {
	array_push($errors, "You must enter your last name.");
}

if ($_POST['organization'])!="") {
	$valid_org = true;
} else {
	array_push($errors, "You must enter your organization.");
}


if ($valid_email && $valid_first && $valid_last && $valid_org) {

	$to = "[email protected]";
	$subject = "GTT FORM SUBMISSION";
	$headers = "From: ".$_POST['email'];
	$date = date("r");
	$message = "Form submission sent from 'Subscribe' at ".$date."\n\n";

	$message .= "Salutation : ".$_POST['salutation']."\n";
	$message .= "First Name : ".$_POST['firstname']."\n";
	$message .= "Last Name : ".$_POST['lastname']."\n";
	$message .= "Company : ".$_POST['organization']."\n";
						$message .= "Title : ".$_POST['title']."\n\n";
						$message .= "Country : ".$_POST['country']."\n\n";
	$message .= "Phone : ".$_POST['phone']."\n";
	$message .= "Email : ".$_POST['email']."\n\n";

					   if(isset($_POST['addtonetwork']) && $_POST['addtonetwork']=='yes') {
		$message .= "YES - Add to network.\n\n";
	} else {
		$message .= "NO - Do not add to network.\n\n";
	}




	if(mail($to, $subject, $message, $headers)) {

		include("includes/thankyou.php");
	} else {
		global $error;
		$error = "Mail could not be sent!";
		include("includes/form_subscribe.php");
	}
} else {
	global $error;
	$error =  implode("<br />", $errors);
	include("includes/form_subscribe.php");
}

} else {

include("includes/form_subscribe.php");
}


?>

When I use that code I get this error...

 

Parse error: syntax error, unexpected T_IS_NOT_EQUAL in /data/17/1/152/115/1804278/user/1953870/htdocs/subscribe.php on line 79

 

This is line 79...

 

  if ($_POST['firstname'])!="") {

my bad. remove the ) before the !

[betsy_ls]

Thanks!  That worked.

 

Now, I was wondering how you keep the information they have already entered into the form when the error message comes up... so they don't have to type everything in again.

[obay]

put the $_POST[] value as the value in the text boxes

 

for example

 

<input type="text" name="firstname" value="<?php echo $_POST['firstname']; ?>" />
<input type="text" name="lastname" value="<?php echo $_POST['lastname']; ?>" />
etc...

Something like this:

<form>
<input type="text" name="input name goes here" value"<?php echo $_POST['input name goes here']; ?>" />
</form

 

Obay beat me to it.
