Loop through ACF to display all possible field values?

field, loops, wordpress

Solution

Anyone else who is having difficulty with this, I resolved the issue by doing the following:

        // must add field key of the field you want
        $field_key = "field_52a087a80a4c6";
        $field = get_field_object($field_key);

        if( $field )
        {
            echo '<div class="acf-task-difficulty-values">';
                foreach( $field['choices'] as $k => $v )
                {
                    echo '<a data-filter=.'.$k.' onclick="return false;">' . $v . '</a>';
                }
            echo '</div>';
        }

You can then style it in your CSS file.

Problem

I am building a site that is using isotope to filter through posts on a page. I'm using advanced custom fields (http://www.advancedcustomfields.com/) and have created a section where the user can set a field for 'Project Difficulty'. I am trying to loop through all of the possible selections to create a list of links that a user can click to sort through (using isotope). I've got this successfully working using 'tags' , but I don't want to tag each project with the difficulty level, I want the user to select it when creating the post in an ACF drop down. To successfully get and display a list of tags in the form of links, I've used this code: ``` <?php $tags = get_tags(); $html = '<div class="post_tags">'; foreach ( $tags as $tag ) { $tag_link = get_tag_link( $tag->term_id ); $html .= "<a data-filter=.{$tag->name} title='{$tag->name} Tag' class='{$tag->slug}'>"; $html .= "{$tag->name}</a>"; } $html .= '</div>'; echo $html; ?> ``` Now I've tried to alter that to get it working with ACF using some code like this: ``` <?php $fields = get_fields(); $html = '<div class="post_tags">'; foreach ( $fields as $field ) { $tag_link = get_fields( $field->task_difficulty ); $html .= "<a data-filter=.{$field->name} title='{$field->name} Tag' class='{$field->slug}'>"; $html .= "{$field->name}</a>"; } $html .= '</div>'; echo $html; ?> ``` But what it is outputting is: ``` <a data-filter="." title=" Tag" class=""></a> ``` and it's not adding any of the correct data. Clearly some of my values are off. How can I loop through the possible options, and add them as a link as I did with the tags? Thanks
