Hi all,

I’ve just created my own block module, and a configuration form for it.

Now I just wonder whether it is possible to add my own validation function before Drupal save the block configuration?

I tried to add the code like:

$form[#validate][] = ‘my_validation_function_name’;

But it seems it doesn’t help.

So the question is whether Drupal support to do this during the configuration of block. If so, then how I can achieve this?

Thanks in advance.
