Unable to add a single `import_images` field without AddOn creating two sections.

[philbirnie]

Problem

I am unable to add a single Import Images field without the add-on creating an superfluous section above -- for example, this code:

		$this->add_on = new RapidAddon( 'Variant Images', 'variant_gallery' );
		$this->add_on->import_images( 'variant_gallery', 'Variant Images', 'images', [ $this, 'variant_images' ] );

Renders two sections that both say "Variant Images."

The first contains the following error (because there not any fields associated with it):

Warning: Invalid argument supplied for foreach() in [[PATH]]/rapid-addon.php on line 425
Warning: Invalid argument supplied for foreach() in [PATH]]/rapid-addon.php on line 432 

The second section renders correctly with the proper image settings as shown in the screenshot above.

To Solve

I have modified the code at line 420 to check if fields exist before adding the section, and this correct the issue i.e.:

			if($this->fields) {
				echo $this->helper_metabox_top($this->name);

				$visible_fields = 0;

				foreach ($this->fields as $field_slug => $field_params) {
					if ($field_params['is_sub_field']) continue;
					$visible_fields++;
				}

			...
			}

However, if I am using the API incorrectly to add the images field, please let me know.

@philbirnie I was not able to replicate this with provided piece of code. Could you share the full code of the add-on you creating?

I understand the problem. I gave the same names the add-on and images section. So, this is expected behavior.

From the screenshots I see that first section - it's the add-on main section. It is named 'Variant Images' because it's how you named the add-on in this part:

$this->add_on = new RapidAddon( 'Variant Images', 'variant_gallery' );

The second section - it is images section and it is named 'Variant Images' because you gave it this name here:

$this->add_on->import_images( 'variant_gallery', 'Variant Images', 'images', [ $this, 'variant_images' ] );
