Languages :: PHP :: multi-page FORM in PHP ?

Dears,

I had this brilliant idea to split a long form on my site re-design into four pages and am now struggling with the how-to. I was told that this was "easily" done in php.

I did some search, here and on google, and found a tutorial on codewalkers.com (http://codewalkers.com/tutorials.php?show=28&page=1). But since I am a serious php newbie I could not figure out how to use this.

Here is what I would like to ask for (and forgive me if this is very basic, I just started out with PHP Visual Quickstart Guide; it's kinda embarassing :-) :
1. Do you have a recommendation on what I should use? And can you guide me on how to use it?
2. If I use the material from the above link, could you help me figure out where to put what? I always love learning new stuff, but now I'm lost.

Yes this is really easy to do.

You've two solutions, equially viable :
1)use $_SESSION variables. Once you pass the form to the next page just set the values to $_SESSION variables ; this requires only a session_start() call at the top of every page sharing the session's data
2) use hidden fields in your FORM, when passing them from page to page (in fact, from FORM to FORM)


Quite automagically, if you put upon reception all variables from a FORM in a given array named $thevars[] and then do this when outputting the next page's FORM :

with this kind of code snippet :

echo <<<EOS <FORM ...> <input... EOS; foreach ($thevars as $var=>$val) echo "<input type=hidden name='$var' value='$val'>"; echo "</FORM>\n";



you'll end up with a nice & complete $thevars[] containing all FORMS' data, ready to be interpreted by the last script.

In case you ask yourself "how to convert my HTML pages into PHP scripts without passing 4 hours on that silly task?", here's the answer :
1) just put this in each HTML page
1a) on top :

<?php // // script machin-chose // // history section // echo <<<EOFILE


1b) on bottom :

EOFILE; ?>



2) rename all files into .php unless you configured your webserver for accepting extensions .htm, .html as PHP scripts (via the "AddType php" entry)

very nice and clean solution, except perhaps for the PHP parsing of HTML files. That's the easy solution ("la voie large" ;-)
