[Resolved] submit var not present

[dartcol]

As a follow up to this thread:
http://www.phpbuilder.com/board/showthread.php?s=&threadid=10277810 I was wondering whether anyone could shed some light.

I have a sequence of three includes to one page, each time some vars need to be passed, others are acted upon and new ones set. When we get to the third page, which is the one from which the user sends data to the db all vars appear but the submit var! So, something like this appears on the page from a foreach statemement:

num: 2
newch: chapter 2
title: Cheesy wotsits

What should appear is this:
num: 2
newch: chapter 2
title: Cheesy wotsits
submit: create new section

To prevent untowrd happenings, I generally check for the submit var before doing anything using if (isset()) etc.

Now, the interesting thing I found it is that if I pass a further hidden variable and check for that rather than the submit variable it works.

Frankly, I haven;t a clue why this might be so apart from that there are two forms on the previous page. they do have different submit names and values though.

Any ideas?

did you try putting:

print_r($_POST);

...at the top of each step to see exactly what is being sent? (assuming your using POST form method)

Thanks for the tip. However, same deal. The submit variable gets lost after submitting the previous form.

The process is like this:

1. edit.html includes form1

2. edit.html takes form 1 vars and includes form 2

3. edit.html takes form 2 vars and includes form 3

4. edit.html takes form 3 vars and includes form 4

5. On submission of form 4 everything goes into db
   [/list=1]
   At step 4 the array outputted to the page is:
   Array ( [newch] => chapter 2 [title] => cheesy wotsits [num] => 2 )

   At step 3 it's pretty much the same give or take one or two variables but includes the previous submit variable.

   Is it a bug? Or is it me? Probably the latter! 😉

I'll put it up tomorrow (got to get back for the football today - Euro 2004! 😃 ). I'm out of here in 10 minutes. Thanks for your help so far.

And the answer. And it was simple. Seems it's all down to single text fields in forms not being submitted on enter. Hence, after I added a hidden field everything worked. It has been talked about before but I thought it was something different. Just goes to show that 'test, test, test' is the best solution for any problem. Here's the link to the previousdiscussion:
