[SOLVED] pass Javascript variable to PHP

[rasherb]

I really want reload a page I have with a huge form on it without losing any information users have typed into the form. Can php access form data before the form is submitted like javascript (document.form.name.value)?

 

Any other ideas for keeping form data on refresh without submitting the form?

 

Any help would be much appreciated!

AJAX.. You will need to pass the info using javascript to a php file.

Why do you need to refresh the page?? :S

Thanks,

So if I use a link to refresh the page...

 

<?php

echo "<form name=\"form\" method=\"post\" action=\"submit.php?useridnum=$usernum\">";

echo "Title: <input type=\"text\" name=\"title\" size=\"70\"></textarea>";

 

echo "<a href=\"";

echo $_SESSION['PHP_SELF'];

echo "?show=1\"><img border=\"0\" src=\"close.gif\"></a>";

?>

 

Where would the java go?

The form has sections (it's huge) I use links and if(isset){} to expand and contract the sections so they are not all on the page at once, confusing the heck out of users.

use multiple pages and process on each page, what you are describing is a confusing way to handle it. or use javascript to show/hide certain areas of the form
