How do I exlude an empty field from being submitted?

[moishy]

I get the form emailed to me, but I get the following:

Product_01:
Product_02: 1
Product_03:
Product_04: 4
Product_05:

So is there a way that I'll only see:

Product_02: 1
Product_04: 4

Thanx.

What form? What emailed to me? What is your problem?
If you are double posting this thread will be closed.

What I'm saying is:
I have a form on my website which you fill out your contact info, and your desired quantity of product.

the form is of this type:

Name: _____
Phone: _____
Email: _____

___ Product 1
___ Product 2
___ Product 3

So I've preveously posted a question about not filling out the required fields, which will earn you to be sent to the HTTP_REFFER.

So that's solved.

So if somebody submits a form, neglecting to fill out his name, the page will refresh, and not submit.

But my problem now is:
that when a costomer is buying 1 of Product_2, The email mailed to me upon submit will say:

Name: John Doe
Phone: [phone]
Email: [e-mail]
Product_01:
Product_02: 1
Product_03:

But I wanted to just remain with:

Name: John Doe
Phone: [phone]
Email: [e-mail]
Product_02: 1

So how do I omit an empty field from being included in the email?

Did I clarify myself?

We can only deduct that from the code that builds and fills the email message with the values. So post that code here and we'll have a look.

As soon as you press the submit button in a form the complete form is send to the server. thus empty fields are also send and will show up as empty in your email you get from this form.
If you do not want this, send the form to the server (to itself) and check in an IF ($submit) {} each var and make a mail to yourself using
mail ( string to, string subject, string message [, string additional_headers [, string additional_parameters]] )
Read more explanation on this on php.net

Here's the code:

[PHP]<?php

/*
Enter the email address below to send the form to:
*/

$my_email = "[e-mail]";


// This line prevents values being entered in a URL

if ($_SERVER['REQUEST_METHOD'] != "POST"){exit;}

// Check referrer is from same site.

if(!(isset($_SERVER['HTTP_REFERER']) && !empty($_SERVER['HTTP_REFERER']) && stristr($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST']))){print "Please enable referrer logging to use this contact form. Your message was not sent."; exit;}

// Describe function to check for new lines.

function new_line_check($a)
{

if(preg_match('`[\r\n]`',$a)){header("location: $_SERVER[HTTP_REFERER]");exit;}

}

new_line_check($_POST['Name']);

// Check for disallowed characters in the Name and Email fields.

$disallowed_name = array(':',';','"','=','(',')','{','}','@');

foreach($disallowed_name as $value)
{

if(stristr($_POST['Name'],$value)){header("location: $_SERVER[HTTP_REFERER]");exit;}

}

new_line_check($_POST['Email']);

$disallowed_email = array(':',';',"'",'"','=','(',')','{','}');

foreach($disallowed_email as $value)
{

if(stristr($_POST['Email'],$value)){header("location: $_SERVER[HTTP_REFERER]");exit;}

}

$message = "";



# This Block I added thanks to your help
# Avoid empty message - If empty - Go back

if(empty($_POST['Name'])){header("location: $_SERVER[HTTP_REFERER]");exit;


}else{

}


# I use this Block not to email me the submit button
# Fields to Avoid
$ex=array();
$ex[]="submit,submit2"; # Where submit is the name of the submit button.

# iterate the $_POST array
foreach ($_POST as $key=>$value) {
if (!in_array($key, $ex)) {
$message.=$key.": " . $value . "\n";
}
}

$message = stripslashes($message);

$subject = "e-Form";
$headers = "From: " . $_POST['Email'] . "\n" . "Return-Path: " . $_POST['Email'] . "\n" . "Reply-To: " . $_POST['Email'] . "\n";

mail($my_email,$subject,$message,$headers);



?>
[/PHP]

[ronverdonk]

Replace the # iterate the $_POST array with:
[php]# iterate the $_POST array
foreach ($_POST as $key=>$value) {
if (!in_array($key, $ex) AND $value > "" AND $value != 0) {
$message.=$key.": " . $value . "\n";
}
} [/php]

Thanks Ronald!
I based my code on what you wrote:
[PHP]# iterate the $_POST array
foreach ($_POST as $key=>$value) {
if (!in_array($key, $ex) AND $value != "") {
$message.=$key.": " . $value . "\n";}
} [/PHP]
