Ever submitted a form and not filled in all the field only to have to fill them all in again? This tutorial shows you how to keep your in-putted data.
To keep the in-putted data in a input field have the value call the php variable for it like this:
value="<?php echo $name;?>"
Here is a simple form with sticky input:
<form method="post" action="<?php $_SERVER['PHP_SELF'];?>">
Name:<input type="text" name="name" value="<?php echo $name;?>"/>
<input type="submit" name="submit" value="submit" />
</form>
If something goes wrong and the form reloads the in-putted name will still be there.
To keep in-putted data in textfields you need to have the code layout slightly different like this:
<textarea name="text"><?php echo $text;?></textarea>
This will keep the text that's inputted into the textarea.
