How to get a term custom field value in WooCommerce? - php

Question

I've created a 'color' custom field for pa_color taxonomy terms, by native ways as follows:
This is my code:
add_action( 'pa_color_add_form_fields', 'themename_pa_color_add_term_fields' );
function themename_pa_color_add_term_fields( $taxonomy ) {
?>
<div class="form-field">
<label for="themename_pa_color">PA Color</label>
<input type="color" name="themename_pa_color" id="themename_pa_color" class="wpColorChoose" />
<p>Field description may go here.</p>
</div>
<?php
}
add_action( 'pa_color_edit_form_fields', 'themename_pa_color_edit_term_fields', 10, 2 );
function themename_pa_color_edit_term_fields( $term, $taxonomy ) {
$value = get_term_meta( $term->term_id, 'themename_pa_color', true );
echo '<tr class="form-field">
<th>
<label for="themename_pa_color">PA Color</label>
</th>
<td>
<input name="themename_pa_color" id="themename_pa_color" type="color" class="wpColorChoose" value="' . esc_attr( $value ) .'" />
<p class="description">Field description may go here.</p>
</td>
</tr>';
}
add_action( 'created_pa_color', 'themename_pa_color_save_term_fields' );
add_action( 'edited_pa_color', 'themename_pa_color_save_term_fields' );
function themename_pa_color_save_term_fields( $term_id ) {
update_term_meta(
$term_id,
'themename_pa_color',
sanitize_text_field( $_POST[ 'themename_pa_color' ] )
);
}
How can I get their values to the place I need?
When trying to use $term->themename_pa_color, it doesn't work.
It works with name and description default fields, like $term->name or $term->description, but not with my field.
That's how I created it, it correctly saves values.

Your code is adding a custom field to the terms from "pa_color" taxonomy… So this is about term meta data which is never included in the WP_Term Object, and so not accessible as a property from that WP_Term Object.
So the answer is in your code. You need to use the WordPress function get_term_meta() like in your own code (in your 2nd function):
$value = get_term_meta( $term->term_id, 'themename_pa_color', true );
echo $value; // Display value
(where $term->term_id is the term Id and themename_pa_color the meta key)…
