I have a repeater fields where one field is a select field (variety). Users have submitted data to that field, but I now want to change that field to a taxonomy field. So I created a custom taxonomy with the same term names as the select field in the existing repeater. Then I added a taxonomy field to the repeater and set it to this custom taxonomy (tax_variety). Now, I want to loop through my posts and for each post, loop through the repeater, then take the value of variety, see if it matches a term name in tax_variety and, if so, set tax_variety to that term.
Here is my code (from inside the loop):
if ( $items->have_posts() ) {
$tax_var = get_terms('varieties_grown', 'hide_empty=0');
$tax_var_array = array();
foreach ( $tax_var as $tax ) {
$tax_var_array[] = array('term_id' => $tax->term_id, 'name' => $tax->name );
}
while( $items->have_posts() ) {
$items->the_post();
$post_id = get_the_ID();
$varieties = get_field('field_57d8b8c860d41');
if ( $varieties ) {
for ($x = 0; $x < count($varieties); $x++ ) {
$v = $varieties[$x];
$key = array_search( $v['variety'], array_column( $tax_var_array, 'name' ) );
if ( $key ) update_sub_field($v['tax_variety'], $tax_var[$key]);
}
}
}
In this case, I used the tax term object with update_sub_field, I also tried just the ID, but neither seems to work. I echoed all the values and they are correct, so it’s coming down to the update statement that seems to be failing.
BTW, the $tax_var_array that I create was basically just to make it easier for me to do the array_search. Probably could have done it with the term objects, but my head is hurting too much to think about it.
Never mind! I fixed it by using the full field keys instead of slugs. Here’s the working code:
if ( $items->have_posts() ) {
$tax_var = get_terms('varieties_grown', 'hide_empty=0');
$tax_var_array = array();
foreach ( $tax_var as $tax ) {
$tax_var_array[] = array('term_id' => $tax->term_id, 'name' => $tax->name );
}
while( $items->have_posts() ) {
$items->the_post();
$post_id = get_the_ID();
if( have_rows('field_57d8b8c860d41')):
while ( have_rows( 'field_57d8b8c860d41' ) ) : the_row();
$variety = get_sub_field( 'field_57d8b8dc60d42' );
$key = array_search( $variety, array_column( $tax_var_array, 'name' ) );
if ( $key ) {
$term_id = $tax_var_array[$key]['term_id'];
update_sub_field('field_5894f9fbbad27', $term_id );
}
endwhile;
endif;
}
}
