I want to create a shortcode to return a string of values, which are the term names. So I can use it to pass data inside a plugin. Anyone cracked this one before?

/**
 * Custom shortcode to get terms for the Formidable plugin
 */

function ALC_post_terms_by_id( $term, $atts ) {
    global $post;

    $alc_Terms = wp_get_post_terms( $post->ID, $term, 'orderby=name&hide_empty=0' );

    $term_array = array();
    foreach ($alc_Terms as $alc_Term) {
        $term_array[] = $alc_Term->name;
    }

    // $atts = shortcode_atts( $term_array() ), $atts );

    return $term_array();
}
add_shortcode( 'term_by_id', 'ALC_post_terms_by_id' );

New attempt

This is the shortcode I use:

[get_terms_by_taxonomy taxonomy="bouwjaar"]

This is the new function after suggestion in the comment by TheDeadMedic

/**
 * Custom shortcode to get terms for the Formidable plugin
 */

function ALC_post_terms_by_taxonomy( $atts ) {

    // return $atts['taxonomy'];

    $taxonomyTerms = wp_get_post_terms( $post->ID, $atts['taxonomy'], 'orderby=name&hide_empty=0' );

    $term_array = array();
    foreach ($taxonomyTerms as $taxonomyTerm) {
        $term_array[] = $taxonomyTerm->name;
    }

    return $term_array; // returns "Array"

    // return implode( ', ', $term_array );
    // implode returns "nothing"
}
add_shortcode('get_terms_by_taxonomy', 'ALC_post_terms_by_taxonomy');

    Have you tried return implode( ', ', $term_array ); instead? May 6, 2014 at 12:33
  • hm almost there. Tried what you suggested, but the implode returns nothing after I pass the array trough it. I'll re-edit te code above.

  • Found it. Your solution did work, I forgot to add the global $post inside the function:). Thanks for the help! Should I add the full function for future reference?

This is the solution to get post terms by taxonomy by shortcode:

/**
 * Custom shortcode to get terms
 */

function ALC_post_terms_by_taxonomy( $atts ) {

    global $post;

    $taxonomyTerms = wp_get_post_terms( $post->ID, $atts['taxonomy'], 'orderby=name&hide_empty=0' );

    $term_array = array();
    foreach ($taxonomyTerms as $taxonomyTerm) {
        $term_array[] = $taxonomyTerm->name;
    }

    return implode( ', ', $term_array );
}
add_shortcode('get_terms_by_taxonomy', 'ALC_post_terms_by_taxonomy');

And you can use it by this shortcode:

[get_terms_by_taxonomy taxonomy="taxonomyname"]
