Simple PHP If statement help (ignore on email send)

[kayz]

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 have 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

sending credit card details by email is crazy.

[scrupul0us]

i assume you're using post to pass the form data

<?php
foreach($_POST as $key=>$value)
{
	if(isset($value))
	{
	//these form fields have data
	//$key is form field name
	//$value is the value of said form field
	}
}
?>

as stated, NEVER email credit card and expiration dates... thats just stupid... if nothing else just email the last 4 digits with the rest represented as asterisks... no need to send the expiration

Hi guys and thank you very much for trying to help me.

That is ane example form as explained above, im just trying to get the thing to work without sending blank fields as i will convert the form into a questionnaire.

The above method still seems to be returning field names that have no entries in it. Is there a particular place i need to place it?

Cheers

[dagon]

try !empty() instead of isset()

[bike5]

<?php
foreach($_POST as $key=>$value)
{
    if(strlen(trim($value))>0)
    {
      echo $key.': '.$value.'<br/>';
    }
}
?>

[dagon]

no versions of the code offered shows up in any of your files

The below is what i have tried just before the headers. Remember i am using $SESSION and also $POST.

<?php 

//let's start our session, so we have access to stored data
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 First 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]);



$mypostData = array(); 

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


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

?>

[dagon]

you dont do anything with the $mypostData array.
