Follow the steps to create taxonomy term meta data.

Step 1: Add meta field to add new term form

We are using hook “{taxonomy}_add_form_fields”. Use the following code snippet and add this in the theme functions.php” file.

function cb_add_term_fields( $taxonomy ) {
  echo '<div class="form-field">
    <label for="cb_custom_meta_data">Custom Meta Data Field</label>
    <input type="text" name="cb_custom_meta_data" id="cb_custom_meta_data" />
    <p>Description for meta field goes here.</p>
  </div>';
} 
add_action( 'departments_add_form_fields', 'cb_add_term_fields' );

Step 2: Add meta field to edit term form

We are using hook “{taxonomy}_edit_form_fields”. Use the following code snippet and add this in the theme functions.php” file.

function cb_edit_term_fields( $term, $taxonomy ) {
  $value = get_term_meta( $term->term_id, 'cb_custom_meta_data', true );
  echo '<tr class="form-field">
    <th>
      <label for="cb_custom_meta_data">Custom Meta Data Field</label>
    </th>
    <td>
      <input name="cb_custom_meta_data" id="cb_custom_meta_data" type="text" value="'.esc_attr($value).'" />
      <p class="description">Description for meta field goes here.</p>
    </td>
  </tr>';
}
add_action( 'departments_edit_form_fields', 'cb_edit_term_fields', 10, 2 );

After updating the code, the edit term screen looks like this:

Step 3: Save term metadata

In the end, we have to save our term metadata field value to our database. To achieve this, we are using the WordPress existing hooks such as “created_{taxonomy}” and “edited_{taxonomy}”. Here, the same callback function “cb_save_term_fields” is used with those hooks.

function cb_save_term_fields( $term_id ) {
  update_term_meta(
    $term_id,
    'cb_custom_meta_data',
    sanitize_text_field( $_POST[ 'cb_custom_meta_data' ] )
  );
}
add_action( 'created_departments', 'cb_save_term_fields' );
add_action( 'edited_departments', 'cb_save_term_fields' );
