How to keep form values after post [duplicate]

Answer 1

If you are looking to just repopulate the fields with the values that were posted in them, then just echo the post value back into the field, like so:

<input type="text" name="myField1" value="<?php echo isset($_POST['myField1']) ? $_POST['myField1'] : '' ?>" />

Answer 2

you can save them into a $_SESSION variable and then when the user calls that page again populate all the inputs with their respective session variables.
