HI @Wpaid, Can you explain what you mean by the code does not work?

You added the dynamic data and it shows in the website.

However you said that "it doesn't works because it only sorted by date" and you want it to order by Random?

@tdrayson
I want to make a Related posts by category, and I want the order is random by category.
But it now show me the posts by date.
The latest post is in top in the list.
In the "Dynamic data", the featured image and the "Title"is a good choice?

@Wpaid
you have the repeater set to custom and you have the post type and count set and nothing else?

@tdrayson
Yes. That's all I set. Query -> Custom-> Post type -> post, and "Post per page" -> 5.
I'm sure I'm going to spoil something. I'm just looking for the right setting.
I pretty much understand what the code does, but something is still missing.
Is there a special setting I can't figure out?
I am not change nothing in your code.
The repeater working well. But when I put the code to the "Code block" there is doing nothing.
With code and without code, same result.
This is the Structure

Did you update the code so you changed the taxonomy slug and changed the post type slug?

Is there a chance we could see a very basic example of this ingenius code getting related Woocommerce products by attribute (pa_year)? Or even just products from same category. It would be much appreciated!

Did you update the code so you changed the taxonomy slug and changed the post type slug?
@tdrayson
I did it. Now good. Working perfect. The category slug was not well filled.
Thank you again.

I'm still having issues with this.
Can anyone confirm if they have tried this in v.3.7 and it works?

Nested inside another repeater is not working, I used toolset relationship to connect two posts.
Could you help on this ?

I'm still having issues with this.
Can anyone confirm if they have tried this in v.3.7 and it works?

Yes, here it works with 3.7!

Hey guys,

Can you please help me how to modify the code for WooCommerce products?

I need to list all the products in the "pizzy" category and sort them by "menu_order". I tried to modify the code, but Oxygen always throws me a 500 error and it can't be saved.

P.S .: After inserting the code into the "code block" and applying. "Hello world" will not disappear either. Unfortunately, I absolutely don't know where I'm making a mistake.

Thanks for this piece of code, it's half working for me and I can't figure it out, hopefully somebody can help me:

. Using Oxygen 3.7

. I've added the code block before my repeater

. When I initially run the code without the "add_action ( 'pre_get_posts', 'filter_plans' );", it works fine, I can see all the records.

. When I run the code with the "add_action ( 'pre_get_posts', 'filter_plans' );", I can see that the filter works as I can see the rows on the output but none of the fields print out, the rows are blank. I re-created the repeater from scratch and the syntax looks fine to me: [oxygen data='custom_acf_content' settings_path='contacts_min'] -- [oxygen data='custom_acf_content' settings_path='contacts_max']

Any idea why the filters would work but the fields wouldn't print?

Many thanks,

Ok, well, I can answer my own questions above, I guess it's an ACF problem as if I insert the field through the "Custom Field/Meta Options" rather than through the "Advanced Custom Field", it works fine.

In short: [oxygen data='meta' key='contacts_max'] works while [oxygen data='custom_acf_content' settings_path='contacts_max'] doesn't.

Hello!
Thanks for sharing this, that is really helpful!

I have a question, regarding this. I need to put the code block inside a code snippet, as I have WPGrid running and the faces using AJAX, so putting it on the page, won't work correctly.

I have the custom params in the repeater element:
post_type=veranstaltungen&posts_per_page=4&custom_query=true

I then have following in a code snippet:

`function dynamic_category_query999( $query ) {

if ( $query->get( 'custom_query' ) ) {

    $query->set( 'meta_key', 'veranstaltung_zeit_anfangszeitpunkt' );
    $query->set( 'orderby', 'meta_value' );
    $query->set( 'order', 'DESC' );
    $query->set(
        'meta_query',
        [
            [
                'key'     => 'veranstaltung_zeit_endzeitpunkt',
                'value'   => gmdate( 'Y-m-d H:i:s' ),
                'compare' => '<=',
            ],
        ]
    );

}

}
add_action( 'pre_get_posts', 'dynamic_category_query999' );`

The question I now have:
Is it possible to add a speicifc identifier like queryA, queryB, queryC etc. so that I cann apply a specific code snippet to only one specific repeater?

Thanks very much again!

Hi @ALL, how if I want to include all categories there?

Thank you very much. It works very well for me!

Hi folks! Anybody can help me out, how to query in this way acf relationship post object? I have a custom post type where user can select other posts from acf relationship fields, and i need to put this posts into a repeater. It would be lifesaver. Thanx!

That would be amazing!! :(

I heard this feature will release on Oxygen 3.8, Amazing!

I have solved this ....contact me if you still need to know how to do it (so we not troll this post...) -> skp: live:indirect_9

@mdsims086 I haven't got it working with the relationship field...

I also have a CPT (custom_webinars) and within a custom field (webinar_speakers) related to a CPT (custom_webinar_speak) --- the page is loading all speakers instead of showing only those related to the webinar. I am using the Oxygen Repeater (with custom query pulling custom_webinar_speak) and added the following code without any luck:

  if ( $query->query['post_type'][0] == 'custom_webinars' ) {
    $query->set( 'meta_query', array(
                                array(
                                  'key' => 'webinar_speakers', //name of custom field
                                  'value' => get_the_ID(),
                                  'compare' => 'LIKE'
                                )
                              ) );

    $query->set( 'no_found_rows', true );
  }
}
add_action( 'pre_get_posts', 'dynamic_category_query' );```

Thanks in advance

for anyone looking for an example for child pages:

CODEBLOCK

<?php
function repeater_dynamic_query( $query ) {  
  $postID = get_the_ID();
  $query->set( 'post_parent', $postID );
}
add_action( 'pre_get_posts', 'repeater_dynamic_query' );
?>

REPEATER

The Repeater Query is set to manual with the following:

post_type=page&no_found_rows=true&order=ASC&orderby=menu_order&posts_per_page=-1

CODEBLOCK

<?php
remove_action( 'pre_get_posts', 'repeater_dynamic_query' );
?>

@yankiara Thanks for this awesome snippet!

I am trying to place product carousels on a product color archive page. Basically, for every category that has products with a certain color, I want to create a carousel with those products. For example, if I am on the "green" color attribute archive page, and products with attribute color:green are in categories Shirts, Pants and Shoes, I want to display a product carousel for each of those categories.

I imagine having to create a repeater with a carousel inside, but I'm not sure how I would dynamically set the query of the carousel inside the repeater. Any ideas?

@mdsims086 I haven't got it working with the relationship field...

I also have a CPT (custom_webinars) and within a custom field (webinar_speakers) related to a CPT (custom_webinar_speak) --- the page is loading all speakers instead of showing only those related to the webinar. I am using the Oxygen Repeater (with custom query pulling custom_webinar_speak) and added the following code without any luck:

  if ( $query->query['post_type'][0] == 'custom_webinars' ) {
    $query->set( 'meta_query', array(
                                array(
                                  'key' => 'webinar_speakers', //name of custom field
                                  'value' => get_the_ID(),
                                  'compare' => 'LIKE'
                                )
                              ) );

    $query->set( 'no_found_rows', true );
  }
}
add_action( 'pre_get_posts', 'dynamic_category_query' );```

Thanks in advance

It works now! This is what I did, I'm sure there is a other ways but wanted to share my findings.

BEFORE THE REPEATER
`<?php
/*
custom_webinar_speak -- CPT holding all the speakers
custom_webinars -- CPT from webinars
webinar_speakers -- field from custom_webinars linking both CPT
*/

function dynamic_category_query( $query ) {

//get Pods object for current post
$pod = pods( 'custom_webinars', get_the_id() );

//get the value for the relationship field
$related = $pod->field( 'webinar_speakers' );

if ( ! empty( $related ) ) {
foreach ( $related as $rel ) {
// add the ID for each related speaker as an array
$post_ids[] = $rel[ 'ID' ];
}
}
$query->set( 'post__in', $post_ids );
$query->set( 'no_found_rows', true );
}
add_action( 'pre_get_posts', 'dynamic_category_query' );
?>`

REPEATER
repeater as a custom query pulling all the speakers (custom_webinar_speak)

AFTER REPEATER
<?php remove_action( 'pre_get_posts', 'repeater_dynamic_query' ); ?>

Thank you for all the previous comments in this thread, they were very helpful. much appreciated!

I got it also running using it for products from WooCommerce:

<?php function repeater_dynamic_query( $query ) { global $post; if ( $query->query['post_type'][0] == 'product' ) { $cat = wp_get_post_terms( $post->ID , 'product_cat', array( 'fields' => 'slugs' ) )[0]; $query->set( 'tax_query', array( array( 'taxonomy' => 'product_cat', 'field' => 'slug', 'terms' => $cat, 'include_children' => false ) ) ); $query->set( 'orderby', 'rand' ); $query->set( 'post__not_in', array($post->ID) ); $query->set( 'no_found_rows', true ); } } add_action( 'pre_get_posts', 'repeater_dynamic_query' ); ?>

Thanks so much for posting this! It was exactly what I needed to get my repeaters working the way they should.

Is it alive here?
I'm total, total noob. I use Meta Box for custom stuff. For starters I just need to obtain a variable, which contains correct post_id for each post inside of a repeater. Once I've got this, there is a big chance that Meta Box helper function or, if I'm lucky, MB Views shortcode, will take care of the rest. Without setting nothing else, but CPT I need to work with, MB helper function gets page ID as $post_id parameter. Repeater reads custom posts name, ID and everything I can set via WP default parameters, but when it comes to custom fields, it shows nothing or i.e. for date type fields current date. How would the BEFORE code look like, if I need just the post_id of posts inside repeater? CPT slug 'podujeti' or something. Thanks

partially SOLVED
It is a problem of Oxygen backend. Frontend shows the data pulled by rwmb helpers in code block just fine. Still struggling with using shortcodes to do the same thing.

but when it comes to custom fields, it shows nothing or i.e. for date type fields current date.

You're definitely not selecting the correct field…

I did some experiments. This put into repeater field echoes page ID, not repeater field post ID:

MB helper function rwmb_get_value( $field_id, $args, $post_id ); then returns $field_id of incorrect $post_id. As I understand, I need to give $post_id argument correct value, then this basic query should work for custom fields.

Why does my code output all posts when it shouldn't output anything?

<?php

function repeater_dynamic_query( $query ) {

	$current_id = get_queried_object_id();
	$query_ids = get_term_meta( $current_id, 'дополнительная_информация', true );
	
	global $post;
	if ( $query->query['post_type'][0] == 'add_cat_info' ) {

    $query->set( 'post__in', $query_ids );
    $query->set( 'no_found_rows', true );
  }
}
add_action( 'pre_get_posts', 'repeater_dynamic_query' );

?>

Hey guys, any tips would be appreciate on this please.

When using pre_get_posts action hook inside oxygen repeater (any custom query):

when updating $query->set('something', 'value'), it does not update his object property $this->found_posts.

This is a really strange behavior....or i missing something ...

  function my_pre_get_post($query){
    ...
    $query->set('somefilter', 'value');
    $query->found_posts // 0 why is that? There is post showing up on the front end
    ...
}
