Getting the page title a repeater field is on from a pageField

[a-ok]

Hi folks,

I have a repeater set up on a 'fabrics' page. When you add a fabric, you then add an image and a colour (per row on a repeater); the colour field is a pageField which lists out all the colours from the Colours section. See screenshot for an example. 

Across the site, where 'related fabrics' come into play, the client will choose, via a pageField, all the relevant fabrics and it'll take the first row of the repeater (image and assigning colour) and display it. See second screenshot as an example. This is all good and works BUT there is one section of the site 'In-Situ' where the client would have to choose a specific colour from a fabric (and not just the fabric).

As the image/colour combos are set up as a repeater (which are added as pages in the CMS under 'Admin > Repeaters' (which is amazing) I can simply tell a pageField, using a custom selector, to show each 'row' from across the site (which would return all the images and colour options for each fabric).

template=repeater_collections_detail_images, include=hidden, sort=name

This works a treat. I can then use the custom page label format which would return the parent title of the page it's on and then the title of the colour chosen.

{parent.title} – {collections_detail_image_colour.title}

I have one issue, however. The parent.title isn't user-friendly and is rather the canonical title of the page, not the actual title of the page, so looks more like a name than a title. See the third and fourth screenshot as an example. 

The only thing I can think of is that these repeaters and their rows are on these specific fabric pages, right? So is there a way for the custom page label format to return the title of THAT page and not the repeater page? See my final screenshot for what I mean. The repeater has a path, for example, .../for-page-1080/ and the page 1080 that it is referring to is the page of the title I am trying to get.

Any ideas? I realise this is a little long-winded but any help or advice would be appreciated.

Just an update. If I put {parent.path} – {collections_detail_image_colour.title} as the custom page label format then it shows the 'for-page...'

I think what I could do is include a hidden field in the repeater and write a addHookAfter to fill this hidden field with the page title on save, then just use that field? Seems a bit odd? But maybe not?

Only thing I'm struggling with is trying to add a hook to a repeater set the value of a field per repeater row.

I thought this would've worked

$pages->addHookAfter('Pages::saveReady', function($event) {
    $page = $event->arguments('page');
    $repeater = $page->collections_detail_images;
    foreach ($repeater as $row) {
        //$page->message($row);
        $row->collections_detail_image_page_title = 'TEST';
    }
});

[a-ok]

$pages->addHookAfter('Pages::saveReady', function($event) {
    $page = $event->arguments(0);
    $repeater = $page->collections_detail_images;
    foreach ($repeater as $row) {
        $row->of(false);
         $row->collections_detail_image_page_title = $page->title;
        $row->save();
    }
});

This is what worked.

Resurrecting this is an old topic)

Is there now an easy way to use the title of a page a repeater field is on in a Custom Page Label Format? Like {getForPage.title} with a special keyword? Probably like {parent.title}, which works.

I solved the problem with the hook, but it could've been easier)
