Remember me PHP Form Validation

[chiefrebelangel]

Hey guys :bounce::bounce::bounce:

Im making a form which has quite many fieds, like 50 fields. The form is using php and i have a database to back it up. I made the necessary errortrapping needed to check for empty fields etc. I can save the values in database everything alright. Up to hear im alright. My problem is the following

When i entered the data and I submit the form an errormesage comes up (on a second page) and i provide a link using $_SERVER[HTTP_REFERER]; to go back, but the previous entered data is of course gone. I want it to stay there.

I dont want to make session variables cause its like over 50 fields, i have typed to many variables as it is ;)

I could of course use the PHPSELF but then I cant get my form to go to another page WHEN user managed to put all data correct.

I read about the header location function but i never get that to work due
to session already sent all the time GRRRRR.

Is it any person who can help me?:crying: please

I have googled for this without any luck, and searched various forums.

for starters, if your form is 50 fields, it should probably be spread across multiple pages. otherwise, that's just bad usability.

if you're typing in a lot of variables, you could probably benefit from using associative arrays instead. i think session variables is the way to go.

heya bwh2 =)

In my case the form with many fields has to be in one page and not really bad usability due to my customer needs a orderform which he writes by hand simply "copied" in electronic form to be able to put the data in electronically.

Well i guess it doesnt have any "easy" way of doing it than using session variables for each datafield, I checked out the associative array thing and I can see the pros of using it. Thanks for

One question. Couldnt i simply do the phpself form trick and do my errortrapping on the same page and then i can easy display errormessage on the same page, without saving session variables, and IF everything ok for the form to relocate to another page. Like i mentioned before I can never get this header location to work. I always get header already sent. can u use another way or relocate Automatically?:chinaman:

Normally i do error checking in the client in javascript then you don't have the problem and
it's faster because you don't call the server. After checking the values i submit the form.
On the form i have a message div that tell's the user what's wrong

To do this you do:

<input onClick="check_insert()" type="button" name="insert" value="insert">

<script language="JavaScript">
<!--
function check_insert()
{
var message_obj = document.getElementById( "message" );
//check the values on the form:
if( your_form.some_value.value == "" )
{
message_obj.innerHTML = "some value must cannot be empty";
return;
}
your_form.submit();
}
//-->
</script>
