Hi, I am very very new to web programming and I want to retain data once the form is submitted. I tried other says but no luck. Could someone point it out for me please?

Code:

<?php
session_start(); // Start the session where the code will be stored.
?>

<html>

<head>
<title>Securimage Test Form</title>
</head>

<body>

<?php
if (empty($_POST)) { ?>

<form method="POST" >
<strong>Name:</Strong><br />
<input id="text" name="usname" />
Code:<br />
<input type="text" name="code" size="12" /><br /><br />

<input type="submit" value="Submit Form" />
</form>

<?php
} else { //form is posted
echo "<center>Sorry, the code you entered was invalid. <a href=\"javascript:history.go(-1)\">Go back</a> to try again.</center>";
if (isset($_POST[username])) return $_POST[username];
}
?>
</body>
</html>

you want to keep the form input fields populated? is that what you mean?? because your form fields are displayed only when $_POST is empty you should break it down like so

PHP Code:


			
<?php
session_start(); // Start the session where the code will be stored.
?>

<html>

<head>
<title>Securimage Test Form</title>
</head>

<body>

<?php

if (isset($_POST['submit'])) {
    //Error
    if (!$_POST['usname']) || !$_POST['code']) {
        echo "<center>Sorry, the code you entered was invalid. <a href=\"javascript:history.go(-1)\">Go back</a> to try again.</center>";
    } else {
        //Process    
    }
}

if (empty($_POST)) { ?>

<form method="POST" >
<strong>Name:</Strong><br />
<input id="text" name="usname" />
Code:<br />
<input type="text" name="code" size="12" /><br /><br />

<input type="submit" value="Submit Form" />
</form>


</body>
</html>
