sorry but u really should be using a credit card gateway like paypal to valadate money.........

getting users credit card numbers to pay for somethink is very tricky business,

let a gateway do it all then ur get no come back.........

trust me..........

this is only a college assignment. just needs to validate and show errors to the user.

flyhoney · November 16, 2008

Just print the values the user submitted with the form.

<input class="violet" type="text" name="NAME" size="30" value="<?php echo $_POST['NAME'] ?>" />

Other notes:

as a general rule it is better to do the PHP stuff at the beginning of the script instead of embedding functions and classes in the html
use double quotes around HTML attributes, i.e. type="text"
close input tag using />

Here is a basic form and form processing code that allows you to display errors next to the form field, to redisplay previously submitted values, and to prevent duplicate form submission. It's all just some conditional statements to control what happens -

<?php
// basic form and form processing code on one page
// w/duplicate submission prevention (using session)

session_start();

// determine if the form processing code has been execuited once
$processed = isset($_SESSION['processed']) ? TRUE : FALSE;

// condition the form variables and setup default values -
$submitted = isset($_POST['submit']) ? $_POST['submit'] : FALSE; // was the form submitted?
$name_field = isset($_POST['name']) ? $_POST['name'] : ""; // condition the form's name field
// add more form fields here - only actual variables are set to prevent injection attempts (most looping or array  map code unconditionally sets any variable name that was submitted)

// the form processing code
// if the form was submitted and not already processed
if($submitted && !$processed) {
$form_error = array(); // array to hold any form validation errors

// validate the form data here (set elements in $form_error to hold error messages)
	if(empty($name_field)) {
	$form_error['name_field'] = "Please fill in the name";
}

// if there were no form validation errors, use the data that was submitted
if(empty($form_error)) {
	// do something with the data here
	echo "The name you entered was: $name_field<br />";
	// indicate that the form data was processed -
	$_SESSION['processed'] = true;
}
}

// the form code
// display the form if it has not been submitted or there are form validation errors
If(!$submitted || !empty($form_error)) {
$error_message = "";
// check for and display any form validation errors
if(!empty($form_error)) {
	$error_message = "Please correct the errors shown -";
}

// display the form, with any errors and  previously submitted values

?>
<?php echo $error_message; ?>
<form method="post" action="">
<label for="name">Name: <?php echo isset($form_error['name_field']) ? $form_error['name_field'] : "Required";?></label><br />
<input type="text" name="name" id="name" value="<?php echo $name_field; ?>">
<input type="submit" name="submit">
</form>
<?php
}

// if data is resubmitted/refreshed, output a meaningful message
if($processed){
echo 'Thank you, the data has already been processed.<br />';
}
?>

here a example for u if the user didnt fill in the form...

try it it on one page ok.......

<?php

if (isset($_POST['submit'])){

$users_name=$_POST['users_name'];

$card_number=$_POST['card_number'];

if (empty($users_name)) {

	$err1="<font color='red'>Please fill in username!</font>";
}

if (empty($card_number)) {

	$err2="<font color='red>Please fill in credit card number!</font>";
}


if( ($users_name) && ($card_number)){

echo "<BR><BR> <font color='green'>Your user name is: $users_name and card number is: $card_number </font> <BR><BR>";

}

}

?>

<form method="POST" action="<?php $_SERVER['PHP_SELF']; ?>">

<?php  $br="<br>"; ?>

Please enter your name <?php echo $err1; ?>

<?php echo $br; ?>

<input type="text" name="users_name">

<?php echo $br; ?>

Please enter card number <?php echo $err2; ?>

<?php echo $br; ?>

<input type="text" name="card_number">

<?php echo $br;?>

<?php echo $br;?>

<input type="submit" name="submit" value="SEND INFO!">

</form>
