[php] How to keep form values after post

I am trying to find what the easiest way to keep form values after post. I am really trying to have to keep from learning ajax right this second for the one form, Plus I am not sure how hard it would be to implement ajax into my already existing google map page. So I am trying to find a way to retain the values of two date fields after submit has been pushed

This question is related to php javascript html ajax

The answer is

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'] : '' ?>" />

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.
