Get custom taxonomy's custom meta from outside the loop - php

Question

I've created a number of custom fields for custom taxonomy. Got no problem pulling their values inside the query. But in this case, I get them repeating as many times as I have posts in this taxonomy.
This is the code with it inside the loop
$tables_terms = $atts['custom'];
$tabargs = array(
'posts_per_page' => -1,
'offset' => 0,
'post_type' => 'customtables',
'tax_query' => array(
array(
'taxonomy' => 'tables',
'field' => 'slug',
'terms' => array(
$tables_terms
)
)
)
);
$tabs = new WP_Query( $tabargs );
if( $tabs->have_posts() ){
while( $tabs->have_posts() ) : $tabs->the_post();
$terms = get_the_terms( get_the_ID(), 'tables' );
foreach ( $terms as $term ) {
$t_id = $term->term_id;
$term_meta = get_option( "taxonomy_$t_id" );
echo $term_meta['term_1'];
}
endwhile;
wp_reset_postdata();
echo $custom;
}
How do I get these to show once, outside the loop?

Answer 1

You can use, get_term_meta;
get_term_meta retrieves metadata for a term.
get_term_meta( $term->term_id, 'your_term_name', true )

Answer 2

So the following code actually worked for me
$term_slug = $tables_terms;
$taxonomies = get_taxonomies();
foreach ( $taxonomies as $tax_type_key => $taxonomy ) {
if ( $term_object = get_term_by( 'slug', $term_slug , $taxonomy ) ) {
break;
}
}
$t_id = $term_object->term_id;
$term_meta = get_option( "taxonomy_$t_id" );
and from there on, I simply echoed each meta like this
echo $term_meta['term_1'];

Try Like that:
Store your output in a array and check when store it that value already exist or not.
$tables_terms = $atts['custom'];
$tabargs = array(
'posts_per_page' => -1,
'offset' => 0,
'post_type' => 'customtables',
'tax_query' => array(
array(
'taxonomy' => 'tables',
'field' => 'slug',
'terms' => array(
$tables_terms
)
)
)
);
$tabs = new WP_Query( $tabargs );
$term_meta_array = array();
if( $tabs->have_posts() ){
while( $tabs->have_posts() ) : $tabs->the_post();
$terms = get_the_terms( get_the_ID(), 'tables' );
foreach ( $terms as $term ) {
$t_id = $term->term_id;
$term_meta = get_option( "taxonomy_$t_id" );
echo $term_meta['term_1'];
if(!in_array($term_meta['term_1'], $term_meta_array)) array_push($$term_meta_array, $term_meta['term_1']);
}
endwhile;
wp_reset_postdata();
echo $custom;
foreach($term_meta_array as $st){
echo $st;
}
}
