Default Add methode to class in constructor?

Hello,

I'd like to extend the forum dm.
It's easy to add new fields within the "forumdata_start" hook, but I also want to include a verify method.

When I add "function verify_fieldname" and "$this->validfields['fieldname'] = array(TYPE_STR, REQ_NO, VF_METHOD);" to "forumdata_start", I get an error, that "verify_fieldname" wasn't found...

Any hint?

I don't think you can use vfmethod for custom fields added to datamanagers unless a function already exists. I get around this problem by checking validation using php like follows:

PHP Code:
'daysprune'         => array(TYPE_INT,        REQ_AUTO'if ($data == 0) { $data = -1; } return true;'), 
There's some good details on datamanagers here, but I assume you've already read that.

Your solution doesn't work for me.
To check the data, I need to access some DM ressources

Are you sure? Make sure you changed it appropriately. If you want to do a more complicated check you could define a function outside the class using another Plugin then use that function in the custom check field.

PHP Code:
function mycustom_check($data)
{
    
// Some long code here
    // ....
    // ....
    // ....
    // return true/false
}

// Try this first:
$this->validfields['fieldname'] = array(TYPE_STRREQ_NO'return mycustom_check($data)');

// If the above doesn't work try this:
// $this->validfields['fieldname'] = array(TYPE_STR, REQ_NO, 'if(mycustom_check($data)) {return true;} else { return false; }');

// This is just a guess I haven't tried/tested it out. 
What exactly are you trying to check for? (Give examples of valid/invalid data)

That's working - that's what Antivirus said and what I also tried.
But the problem is, that "mycustom_check" can't access class ressources.

If the check will fail, I cannot use "$this->error()" for example.

Well then but the contents of mycustom_check directly inside the string instead, does that not work?
like:
PHP Code:
$string 
' /* Do some long check */
 if($data != "something")
 {
     /*$this->error("You cant do this or something()*/
 }
 else
 {
     return true;
 }

'
;
$this->validfields['fieldname'] = array(TYPE_STRREQ_NO$string); 
Does that not work? Does it generate errors or something? Have you test your validation code independently to ensure that it works in the first place?

Or:
PHP Code:
function mycustom_check($data)
{
    
// Some long code here
    // ....
    // ....
    // ....
    // return true/false
}

$this->validfields['fieldname'] = array(TYPE_STRREQ_NO'if(!mycustom_check($data)) { $this->error("Some error message!");} '); 
How about that? (If you only need to use the error method).

What are you checking for/validating for? Is there not already a validation method in the Base Datamanager?

Thanks. Nice idea.

In the actual case, that will solve my problem.
