Error handling/Catching mistakes when submitting something in admin_config

[LaocheXe]

Working on a plugin, and I am trying to add a "error message to admin/user when they submit something that is already in the database table, and if they left something blank.

I thought putting in an if statement in beforeCreate($new_data,$old_data) would work, but seems it's being ignored, and still submits the data (which in my case for testing, nothing is filled out.)

Or should I have put that in the onCreateError section?

add required parameter to needed field
maybe you should use beforeUpdate() if it is editing. beforeCreate() is for the new record only.
BeforeCreate for the new record works, can you add the example of your code?
And you still can use the type method and do all checks and messages yourself.

So to make the data required, I would add to the array 'validate' => 'value' - however, can I change the 'value' to something else? There isn't anything in the documentation about it - when I add that to the dealership_id, it won't let me continue, even when I do select a dealership. Or do I have to setup the value some where else in the admin_config?

I have no idea, I think that it is write parameter 'required'=> 1, or single parameter 'required'=> 1
there is test if($data === false) - with 3x= it has to be boolean value returned so return false, not nothing.
I hope I will do some stuff with the new version next month so I will find some real examples. I don't have time now. You forget this stuff when you don't work with it too often.
Are you sure that you are using this for new records only?

'validate' => true

[Jimmi08]

I don't know what validate is for, sorry, I always use required.

[LaocheXe]

That is requirement, makes the field required.

'validate'		=> true,

This indeed sets the field as required.

@LaocheXe For checking if a field is filled in, use the validate option. Do you have other needed tests? Those can go in the public function beforeCreate() method (and beforeUpdate())

You can try my Cookbook plugin, or Wrapper to look for inspiration.

I guess that the count, check if one field is already in database wont work like it used to?

I have this:
$check_fivem_name = $sql->count('vehicles_exe', 'v_fmname', 'v_fmname = '.$fivem_name.'');
if($check_fivem_name > 0)
{
$errMsg = "error message here";
return $errMsg;
}
else
{
return $new_data;
}

so my question is, does the 'filter' do anything like this, would 'filter' be used for this?

[Moc]

Filter is used for filtering options like these:

In your case, I would use this code:

public function beforeCreate($new_data, $old_data)
{

	$check_fivem_name = e107::getDb()->count('vehicles_exe', 'v_fmname', 'v_fmname = '.$new_data['fivem_name'].'');
	
	if($check_fivem_name > 0)
	{
		e107::getMessage()->addError("error message here");
		return false; 
	}
	
	return $new_data;
}
