[SOLVED] PHP Form Question

[refiking]

On the action page, I check certain fields to make sure they are only digits.  If not, it returns false.  What I'd like to do is show the form again with the responses the user entered, but leaving the incorrect fields blank.  Is that possible?

This can take a while,

The way i done it was on the PHP Checking page make it check each input one at a time such as

if($_POST['username'] == ''){
$error1 = 'You Did Not Enter A Username';
}else{
$error1 = '';
} 

 

And then assign each of these errors to a session as well as all the inputs and then if an error occurs on a certain input then make it blank such as

 

if($error1 != ''){
$username = '';
}

 

Then back on your form page in the input tag have, input value='<? echo (your session id) ?>'

 

I hope you can make sense of that it is quite hard to understand and explain

I'll go 1 ahead of you gazalec and tell him tht whn doing his validation, he should store the errors in an array or something, and then return them to the page, lemme giv u an example

 

if($_POST['username'] == ''){
$errors[] = 'You Did Not Enter A Username<br>';
}
if($_POST['password'] == ''){
$error[] = 'You Did Not Enter A password<br>';
}
if($_POST['fullname'] == ''){
$error1 = 'You Did Not Enter your Full name';
}

then after tht all thts done, you return the array and break it apart and diplay it or something

I got everything else updated, but what is a session id?

The session_id is only necessary if you are not using session_cookies, and if you are not and you are worried about SEO I would suggest doing so.

 

www.php.net/session  will help you learn about sessions.

Can you give me an example of what it looks like?

 

input value='<? echo (your session id) ?>'

[per1os]

// form.php

<?php
session_start();
?>

<input type="text" name="full_name" value="<?php isset($_SESSION['fullname']):$_SESSION['fullname']:''; ?>" />

 

// process.php

<?php
session_start();

foreach ($_POST as $key => $val) {
    $_SESSION[$key] = $val;
}

$errors = array();
if($_POST['username'] == ''){
   $errors[] = 'You Did Not Enter A Username<br>';
}
if($_POST['password'] == ''){
   $errors[] = 'You Did Not Enter A password<br>';
}
if($_POST['fullname'] == ''){
   $errors[] = 'You Did Not Enter your Full name';
}

if (count($errors) > 0 && $errors[0] != "") {
    include('form.html');
    die();
}else {
// process the data here
}

?>

 

What I am getting at is you do not necessarily need to define the session id, in fact given the code I posted session would be useless too. Do not worry about the echo your session id crap, it is really useless as the best way for sessions is via cookies and even it is not setup with COOKIES and you are using SESSIONS PHP will automatically append the SESSION id to the form.

Here is my line 110

 

Borrower's Last Name: <input type="text" name="name" value="<?php isset($_SESSION['$name']):$_SESSION['$name']:''; ?>" /><br>

[per1os]

<?php isset($_SESSION['$name'])?$_SESSION['$name']:''; ?>

 

Replace that, forgot the ? instead of :
