Hi guys i have a pretty large working form, when the user dosent fill in a field and submits the form i still receive the field name(s) with a blank entry.. for a large form its a lot to look at when it arrives to see what has been filled in and what hasnt.

Because it is a large form, some areas will be filled in and others will be ignored. What i want is the form to send me only those fields that has been filled in.


This is my "example" working processor, i know it requires a simple if statement, but ive tried many without much luck, your help would be much appreciated.

Cheers





<?php

session_start();

$receiver = '******@hotmail.com';
$subject = 'Website - Feedback';
$headers = 'info@************';


$err_msg = '';
if((!$name)){
$err_msg = '<br />The following fields are missing, please insure you have filled out each field <br /><br />';

if(!$name){
$err_msg .= "* Your Name<br />";
}
include 'index.php';

exit();
}


$arr= array();

$arr[0] = "\n\n Name: ";
$arr[1] = $_SESSION['name'];

$arr[2] = "\n\n email_address: ";
$arr[3] = $_SESSION['email_address'];


$arr[4] = "\n\n membership_type: ";
$arr[5] = $_SESSION['membership_type'];


$arr[6] = "\n\n terms_and_conditions: ";
$arr[7] = $_SESSION['terms_and_conditions'];


$arr[8] = "\n\n name_on_card: ";
$arr[9] = $_POST['name_on_card'];



$arr[10] = "\n\n credit_card_number: ";
$arr[11] = $_POST['credit_card_number'];


$arr[12] = "\n\n credit_card_expiration: ";
$arr[13] = $_POST['credit_card_expiration_date'];


$content = ($arr[0] . $arr[1] . $arr[2] . $arr[3] . $arr[4] . $arr[5] . $arr[6] . $arr[7] . $arr[8] . $arr[9] . $arr[10] . $arr[11] . $arr[12] . $arr[13]);

mail("$receiver", "$subject!", "$content", "From: $headers");
header("Location: thankyou.html");

?>

You can try some thing like this

<?php

$mypostData = array();

foreach($_POST as $key=>$value) {
if($value != "") {
$mypostData[$key] = $value;
}
}

print_r($mypostData); // This will show all the fields that have values inside it


Let me know how it goes please

I would have done this like this:


//Set the field labels for each form element here
$arrNames = array(
'field_name' = > 'Field Label',
'field_name_2' => 'Field Label'
);

//Now run through the post variables and see if they exist

$content = '';

foreach($_POST as $key=>$val){
if(!empty($val)){
$content .= $arrNames[$key] . ': '.$val .'\r\n';
}
}

//Now do you mail call
mail("$receiver", "$subject!", "$content", "From: $headers");
header("Location: thankyou.html");



I hope thats right. Been a long day.

Oh and one more thing, you dont need those quotes around the $receiver and $content, and if you eliminate the exclamation point, you dont need it on $subject either. I would also define the full headers in your $headers variables, and then eliminate the quotes around headers.

Sorry I missed that when I copied and pasted your mail send code.

Really appreciate your help guys, still learning PHP.

unexpected '=', expecting ')' (where the field names are)

Hmm this returns the following error:

Array ( [name_on_card] => hfgh [credit_card_number] => fghf )
Warning: Cannot modify header information - headers already sent by (output started at /home/locateme/public_html/test/form_process.php:64) in /home/locateme/public_html/test/form_process.php on line 67


It still remains to display field names when they are carrying no entry when its being sent to my email.

Any output before header() function will produce such types of error
so make sure that no echo,print,print_r(),var_dump() statemets before header()

in this case remove that print_r() statement

hope it helps you

I think i am making an error somewhere by placing it in the wrong place? I tried csparks solution by replacing the field names with my session variables right?

With HivelocityDD's solution i placed his just above my headers...


Here are the full test form that im getting to work if it helps somebody.
