yupp hykc, u would need 2 pages for this.

name.php

name2.php

<?php
if ($_POST['myname'])
{
echo "name ok";
}
else
{
echo "please enter name";
}

where the sequence is name.php, followed by name2.php

hykc

ok thanks

that means it always need to have 2 pages to handle form
so i always need to pass value from page2 to page1 if it found error on the form fields?

adrian_quah

that's right...but shd be passed from page1 to 2... 😃

hykc

if page2 found error in user input, how can i go back to page1
and the input field can retain the value?

just like those registration page.
user input fields, but some of the field got error, and it returns back to the form page, but the already filled value will retain,
how to do that? should i use session to save the value?

That's not true. You could process a form all with one page.

In your submit variable, just give it a name <input type="submit" name="submit" value="Submit Form">

Then to check if the form has been submitted, use isset(). Here's an example

<?

if (isset($_POST['submit'])) { // fom has been submitted. Process the form
   echo "Your name is " . $_POST['name'] . "<br>\n";
   echo "Your email is " . $_POST['email'] . "<br>\n";

} else { // form has not been submitted. display form
?>

<form method="post" action=<?=$PHP_SELF;?>">

Name: <input type="text" name="name"><br>
Email: <input type="text" name="email"><br><br>

<input type="submit" name="submit" value="Submit Form">

<form>

<?

// end if statement
}

?>
