Hi-

given the following code:


...

$evalCase = returnYesOrNo();

if ($evalCase) {
 foo();
} else {
 bar();
}

In the above example, I want returnYesOrNo() to present a form where the user can say Yes or No, much like a confirmation delete dialog. If the user clicks yes, I want a TRUE returned to $evalCase, if no, a FALSE returned.

The way I understand form buttons, they must point to a form_submit callback, and from there, any arbitrary code you instruct the form_submit_callback to execute executes.

I guess what I want is the form_submit_callback to return a value to the $evalCase var. Is that possible? Or do I just need to structure my code so that the last thing it does is render the form, and the submit calls one of two different callbacks which accomplish what I want?

thanks,
geremy

Please have a look at the Forms API Quickstart Guide.

Hi-

Thanks for the advice. I may have overlooked something. #4 towards the bottom indicates:

"To determine where the user should be sent after the form is processed, the _submit function can place a path or URL in $form_state['redirect'] which will be the target of a drupal_goto; every form is redirected after a submit. If you store nothing in $form_state['redirect'], the form will simply be redirected to itself after a submit. It is polite to use drupal_set_message() to explain to the user that the submission was successful."

So basically, according to this, there is no way to accomplish what I'm trying to do? I don't want to redirect to another URL, I want to return to a calling function with a value.

thanks,
geremy

What you are saying does not really make sense.

I don't want to redirect to another URL, I want to return to a calling function with a value.

What do you mean return to a calling function. The end result of all page calls or form submits, the very end result, is the display of a page. This 'function' you speak of is your form submit function.

Instead of having a form submit call a new page upon completion, I wanted to know if I could have it issue a return instead.

That way, I could do this:

$status = drupal_get_form_return(YesOrNoForm);
if ($status == 'no')
...
else
...

So, in this code snippet, $status is populated by a return value returned from the YesOrNoForm submit function. I make decisions through the rest of the code based on what this form returned. I think it just wont work like this, just wanted to know if I was overlooking something.

You make your decisions in the submit function. If you need to set a value that persists to be picked up somewhere else, then use drupal persistent variables and the drupal_set_variable and drupal_get_variable set of functions and you can pass whatever you need around.
