How to keep values in html form when there is an error.

[pahunrepublic]

Hi everyone!

I have this registration form code:

<?php 
include_once 'dbinfo.php';
if(isset($_POST['kuldes']))
{
$name = $_POST['nev'];
$username = $_POST['felh_nev'];
$password = $_POST['jelszo'];
$email = $_POST['email'];
$phone = $_POST['telefon'];
$gender = $_POST['sex'];
//$memip = $_SERVER['REMOTE_ADDR'];
$date = date("d-m-Y");
if($name == NULL || $username == NULL || $password == NULL || $email == NULL || $phone == NULL || $gender == NULL)
{
echo "Please complete the form below or one of the boxes is empty.";
}
else
{
if(strlen($username) <= 3 || strlen($username) >= 30){
$final_report.="Your username must be between 3 and 30 characters..";
}
else
{
$select_dbase="SELECT * FROM users WHERE username='$username'";
$result=mysqli_query($connect, $select_dbase);
if(mysqli_num_rows($result) != 0)
	{
	$final_report.="The username is already in use!";  
	}
else
{ 
if(strlen($password) <= 6 || strlen($password) >= 12){
$final_report.="Your password must be between 6 and 12 digits and characters..";
}
else
{
if(!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)){ 
$final_report.="Your email address was not valid..";
}
else
{
if(!eregi("^[0-9]{1,3}-[0-9]{1,3}-[0-9]{1,10}$",$phone)){
$final_report.="Phone number is invalid. Only numbers with hyphen. Allowed format: countrycode-areacode-phonenumber";
}
else
{
$insert_dbase = 'insert into 	users (
				name,
				sex,
				email,
				phone_number,
				username,
				password
				) 
				values
				(
				"' . $_POST['nev'] . '",
				"' . $_POST['sex'] . '",
				"' . $_POST['email'] . '",
				"' . $_POST['telefon'] . '",
				"' . $_POST['felh_nev'] . '",
				"' . md5($_POST['jelszo']) . '"
				)';//PHP MYSQl development p.316
mysqli_query($connect,$insert_dbase); 
$final_report.="Thank you for registering, you may login."; 
}}}}}}}
?>

<h1><a href="login_form.php">USERS</a></h1>

The script above works but when it displays an error message about the submitted content it cleans the whole HTML form and the user has to type again. It is annoying. How can I make this script to keep user added values in the html form showing the error messages?

Google "make html form sticky" for more, but as an example:

 

<input type="text" name="nev" size=25>

//would become

<input type="text" name="nev" value="<?php if( isset($_POST['nev']) ) { echo $_POST['nev']; }" size=25>

Thanx!

What do you mean by sticky? Not secure?

No, sticky, as in the entered values "stick" in their fields when reloaded.
