  • Thanks again for the help – I think I’ve solved the problem! It was all about handling the loops properly.

    Keep up the good work!

  • Hi guys,

    Thanks for your help firstly! I’m really impressed with the quality of this plugin, I know I’m trying to do something tricky here with only a working knowledge of PHP. Everything else I’ve used ACF for (lots of applications!) works like a charm straight out of the box.


    I tried removing the postdata functions, but that doesn’t seem to have changed anything.

    Taking the $idlist declaration out of the loop does seem to have helped- I set up two test repeater rows and posts chosen in both are being affected.

    However – only the values from the last repeater row are being applied. I.e. I have two sales, one takes $50 off a group of posts, the second takes $150. Now all the posts selected are showing $150 reduction.

    This is the current code I’ve put in a test page template to get the print:

    if(get_field('sales', 'option')):
    	while(has_sub_field('sales', 'option')):
    		$saletype = get_sub_field('sale_type');
    		$discount = get_sub_field('discount_amount');
    		$saleitems = get_sub_field('devices_on_sale');
    		if( $saleitems ):
    		    foreach( $saleitems as $post):
    				$thisid = $post->ID;
    				$idlist[] = $thisid;

    Which yields:
    100Array ( [0] => 3391 [1] => 3410 [2] => 3412 ) 150Array ( [0] => 3391 [1] => 3410 [2] => 3412 [3] => 1292 [4] => 751 )

    So by my understanding, this is adding both groups of selected posts to the same array.

    Perhaps during the foreach loop, the $post->$ID can be stored differently… I have a vague idea – what I need is not a single named array, but some kind of anonymous array that can be referenced differently somehow, when I need it?

    Alternatively, could I create a “name” text subfield for each repeater row to provide each row with a unique identifier, then reference the related array from that somehow?

    Argh! Any further help much, much appreciated! Cheers for having such great support!

  • This is no longer relevant- delete if you wish

  • P.S. – It occurs to me that I may be able to use a different methodology here-

    We have pages on which category posts are displayed – technically in the loop on those pages, for each post I can check if that post has been selected for a sale, and do whatever I want to the post formatting then – correct? If you could point me in the right direction on how to approach either of these methods I’d greatly appreciate it. Thanks again!

  • Hi there, thanks for your response!

    To clarify, now I have set up an Options Page with a repeater field called “Sales”. This repeater contains three fields:

    “Sale type” – Select – Fixed $ amount / Fixed % discount
    “Discount” – Number – Amount of discount
    “Devices” – Post Object – Selects applicable posts

    Then, for the main device post type, those three fields will be duplicated. Now what I need is a way to pass those values to the fields in the posts chosen. I understand I can use update_field() – I’m thinking I can write a loop that collects the post IDs from the post object field and then uses update_field() to apply the values selected to those posts.

    That seems to make sense- but then I’m not sure how I would even call the update_field() action or where that would live. I am far from an expert in WordPress plugin coding, so any help is much appreciated!
