    advanced custom fields - Getting property of non-object when looping through post objects from ACF

    matteradmin8PV0评论

    I am building a site using Root's Sage Wordpress theme which uses the blade templating engine.

    I have a repeater field in ACF with many post objects. When I foreach loop through the repeater to retrieve the post objects, I am getting a Notice: Trying to get property of non-object errors. When I turn off WP_Debug, these errors are not present and the following code works as expected.

    Below is a snippet of the code used:

    
global $post; 

@foreach($page_column as $pages)


    {{-- If the link is internal --}}
    @if($pages['link_type'] === "Internal")

        @foreach($pages as $post)

            @php 

            setup_postdata($post); 

            @endphp

            <li class="footer__list-item">

                <a class="footer__link" href="{{get_the_permalink($post->ID)}}">{{$post->post_title}}</a>

            </li>

            @php wp_reset_postdata(); @endphp

        @endforeach

    @endif

@endforeach

    Below is what is output:

    What is interesting is you can see the code is working as intended because below most of the error messages, you can see the post title being output. I also do not understand why there are multiple errors thrown per page as the code is retrieving all the pages from the repeater field successfully.

    From what I found when looking up the error, I added in the setup_postdata($post) to see if that would fix the issue however that does not seem to have worked.

    What am I doing wrong here?

    Reset to default 1

    Nevermind, after a couple of minutes, I figured out the issue.

    Instead of passing the $post->ID into get_the_permalink, I can just not pass any parameters in as the setup_postdata($post) takes care of this.
