my_cforms_logic - syntax for $cformsdata

uri=local(development); browser=firefox2;wp=2.7; my-function.php is in plugins/cforms folder.

I need help understanding the syntax for $cformsdata.

I have a form (say #9) that is part of a multipage form; "next form after this" = form#10. Among other things, form#9 is used to select a 'Diary size' using radio buttons – the options are A5, B5 and A4. Depending on chosen diary size, I want to change the next form to form#11 or form#14 (or leave as form#10). BTW in the table "wp_cformsdata", the field_val for field_name = "Diary Size" is = "A5"or "B5"or"A4".

I've tried several alternatives based on "if ( $setting == "nextForm"){:
if ( $oldvalue=='10' && $cformsdata['data']['cf9_field_4-3'] == 'checked') return 14;}
if ( $oldvalue=='10' && $cformsdata['data']['diary size'] == 'A4') return 14;}
if ( $oldvalue=='10' && $cformsdata['data']['cf9_field_4']=='A5' ) return 10;}
if ( $oldvalue=='10' && $cformsdata['data']['cf9_field_4-3'][checked] == 'yes') return 14;}
if ( $oldvalue=='10' && $cformsdata['data']['Diary size']=='A4' ) return 14;

None of these work. Can you assist please?

If uncertain about how to access the data array and the structure of it, have cforms send you a test mail (the below example is in the file under my_cforms_action()):

@mail('your@email.com', 'cforms my_action test', print_r($cformsdata,1), 'From: your@blog.com');

PS: Generally, v10.1 will be released soon that'll fix some MP feature issues (however this is not connected to the above).

Maybe I have misunderstood the purpose and functioning of 'my-functions.php'.

I tested cforms.php at line 249- does the 'logic' function exist? It evaluates to 'no'.

Tested putting the logic function directly into cforms.php – everything runs like clockwork.

Obviously I am missing something here; and probably pretty basic too. :(

Suggestions?

did you uncomment the logic function in my-functions.php?

by default *all* functions are commented out:

Well, I DID say it was something pretty basic <grin>.

Me bad. I saw the uncomment reference but it didn't occur to me that all the functions were commented out.

Many thanks.

The function works perfect when cformsdata is on the current form. But if the data criteria refers to a page prior to the current page then the function doesn't work. Perhaps this is because it relies on trackf.

Example: page1 of a multi-page form has a data field called 'size'.
Say, I have completed page 1, page 2, and page 3 in the multi-page form.
Now I want to branch depending on the value of "size" in page1.
As I see it, the normal syntax doesn't work because it will only 'look' at the cformsdata from page 3.

Am I missing something?

yes, if you need to access data from a previous multi-part form, you need to access the $_SESSION array, that's where all the data is stored meanwhile.

for testing/understanding you might want to print out the array structure, just add a:

echo '<pre>'.print_r($_SESSION,1).'<pre>';

<thud> = sound of head hitting desk.

Of course! Changed "cformsdata" criteria to "$_SESSION['cforms']blah.." and worked a treat.

Thank you

I'm so glad I found this thread! I've been struggling for over a day to get a conditional multipage form working, whereby the next page you jump to is dependent on data that you entered on a previous page. I did the echo '<pre>'.print_r($_SESSION,1).'<pre>' thing as a debug aid to see how to access the values in the $_SESSION array, set up the if statements, and it works great. Being forced to learn PHP, too. sf-wink
