eMail form with validation and sticky forms on one page

Description

This form is all processed on the same page. Rather than have the data shuttled from one page to another it handles and displays the data on this one page.

An advantage to this is that I will be able to use 'sticky forms'. Meaning that the users data will remained submitted if they require to re-enter any information.

Code

```
<?php
```

$page_title = 'eMail form with validation and sticky forms on one page';

```
if (isset($_POST['submit'])){
```
```
if(strlen($_POST['name'])>0)}
```
```
$name = true;
```
```
} else {
```
```
$name = false;
```

echo '<br /><p>Please enter your name.</p>';}

```
if(strlen($_POST['email'])>0)}
```
```
$email = true;
```
```
} else {
```
```
$email = false;
```

echo '<br /><p>Please enter an eMail address.</p>';}

```
if(strlen($_POST['username'])>0)}
```
```
$username = true;
```
```
} else {
```
```
$username = false;
```

echo '<br /><p>Please enter a username.</p>';}

```
if(strlen($_POST['password1'])>0){
```

if ($_POST['password1'] == $_POST['password2']){

```
$password = true;
```
```
} else {
```
```
$password = false;
```

echo '<br /><p>Passwords need to match.</p>';

```
} else {
```
```
$password = false;
```

echo '<br /><p>You forgot to enter a password.</p>';}

```
if(strlen($_POST['message'])>0)}
```
```
$message = true;
```
```
} else {
```
```
$message = false;
```

echo '<br /><p>Please enter a message.</p>';}

if($name && $email && $username && $password){

```
$body = "Hello {$_POST['name']},\n
```
