Form Data to Email loop not working

[cbrown131]

I have a number of form pages with about 25 fields each. I am wanting to email the data collected in these forms and have been trying to accomplish this by looping through the form posted variables so that I don't have to manually grab each field for each form. Everything in the script works except the loop. I am fairly new to PHP and any help would be greatly appreciated.

Here is my code:

<?
$to = &quot;jhandy@test.com&quot;;
$subject = &quot;New Form Submission&quot;;
$from = &quot;webmaster@test.com&quot;;
$message = &quot;A new form has been submitted from the website:\n\n&quot;;
do {
$message .= key($_Request) . &quot;: &quot; . $_Request[key($_Request)] . &quot;\n&quot;;
} while(next($_Request));
mail($to, $subject, $message, &quot;FROM: $from&quot;
?>

Thanks!

try this:

foreach($HTTP_POST_VARS as $key=>$value) {
message .= $key.':'.$value.&quot;\n&quot;;
}

Andreas,

Thanks for the reply. Unfortuneately this did not work either. It stops processing at this loop for some reason. With your code, it didn't even send the mail with the &quot;a new form has been submitted&quot; like I get with the code I originally posted in this thread. Any other suggestions?

You use the $_REQUEST superglobal array. Andreas57 used specifically the POST vars.

It depends on how you send the form data to the script, the method attribute of the <form> tag determines how they appear in PHP (according to the delivery via HTTP).

$_REQUEST is a combination of POST, GET and other variables depending on your version of PHP. I'd go with the $_POST and set the method to POST.

The loop that andreas57 writes is fine. You might just have to change the array that is being iterated:

foreach($_REQUEST as $key=>$value) {
 message .= $key.':'.$value."\n";
}

Again, I'd change the method to POST or with $_REQUEST you'll get $_FILES, $_COOKIE etc. and might not want those.

DRJ478,

That do you mean by &quot;change the array that is being iterated?&quot; Forgive my ignorance, but I am just learning this stuff. I don't believe I have an array in my code. What I posted initially is the only PHP code I am using. Am I supposed to have something else there as well? Thanks!

$_REQUEST is an array. It is a multidimensional variable that is keyed by the fieldnames in your form.

Let's say you have the following tag in your HTML:

<input type=&quot;text&quot; name=&quot;mytext&quot;>
<input type=&quot;text&quot; name=&quot;anotherText&quot;>

The user enters Hello World into the textfield called mytext and the numeral 6 into the field named anotherText and submits the page to your PHP script.

In your PHP the $_REQUEST array contains the following information in abstract terms:
fieldname is the array key and value is the value of the array element.

echo($_REQUEST[mytext]);

prints Hello World.

echo($_REQUEST[anotherText]);

prints 6.

The foreach loop in the example posted goes element by element through the array and assigns the key (fieldname) to $key and the passed value to $value. The process of looping through the array is called iteration.

Ok?
