Add a little support for template_ids arrays in Page Reference field migrations

[gornycreative]

Sorry I'm working in @gebeers RepeaterMatrix fork right now, but if you could add around 3200 in RockMigrations.module.php:

(This is below the $key === "template_id" conditional test block.)

	if ($key === "template_ids") {
        foreach($val as $sub => $tpl_name) {
          if (is_string($tpl_name) and $tpl_name !== '') {
            $tpl = $this->getTemplate($tpl_name);
            if (!$tpl) throw new WireException("Invalid template_id");
            $val[$sub] = $tpl->id;
          }
          $data[$key] = $val;
          continue; // early exit
        }
      }

This would allow the 'Selectable Pages > Additional Templates' setting on Page Reference fields to migrate the 'template_ids' setting properly with template name references into of raw ids in a similar manner to the template_id setting conversion.

Hey @gornycreative thx, looking good. But could you please give a little more context until I have time to look into it?

When you have a Page Reference inputfield, there are two different template options settings:

With the standard migrate() config array, the template_id setting gets processed fine if you use a template name instead of the template_id - the green checkmark.

The template_ids setting does not get processed if you use template names. Nothing appears.

Adding the processing block I wrote above allows template names to be used in that template_ids setting.

@gornycreative I've just added this feature to the latest release of RockMigrations!

It will also show you the correct code to copy&paste:

Thanks!
