创建新的分类、添加额外的字段、注册术语和额外的字段值？

时间：2019-06-10 作者：cap340

我需要创建一个新的分类法（nbateam），向这个分类法添加额外的字段（\'code\'，\'color\'，…）AND 插件启动时注册它们。

现在，除了为我创建的额外字段注册值之外，我可以做任何事情。

我使用的代码：

<?php
// Taxonomy part
add_action( \'init\', \'create_nbateam_taxonomy\', 0 );
// Extra fields
add_action( \'nbateam_add_form_fields\', \'add_extra_fields_to_nbateam_taxonomy\' );
add_action( \'create_nbateam\', \'save_extra_fields_to_nbateam_taxonomy\' );
add_action( \'edit_nbateam\', \'save_extra_fields_to_nbateam_taxonomy\' );
add_action( \'nbateam_edit_form_fields\', \'edit_extra_fields_to_nbateam_taxonomy\' );
// Register terms
add_action( \'init\', \'register_new_terms_to_nbateam_taxonomy\' );

function create_nbateam_taxonomy() {

    $labels = array(
        \'name\'                       => _x( \'Nba Teams\', \'Taxonomy General Name\', \'nba-teams\' ),
        \'singular_name\'              => _x( \'Nba Team\', \'Taxonomy Singular Name\', \'nba-teams\' ),
        \'menu_name\'                  => __( \'Nba Teams\', \'nba-teams\' ),
        \'all_items\'                  => __( \'All Nba Teams\', \'nba-teams\' ),
        \'parent_item\'                => __( \'Parent Item\', \'nba-teams\' ),

        \'add_new_item\'               => __( \'Add New Item\', \'nba-teams\' ),
        \'edit_item\'                  => __( \'Edit Item\', \'nba-teams\' ),

        \'popular_items\'              => __( \'Popular Nba Teams\', \'nba-teams\' ),
        \'search_items\'               => __( \'Search Nba Teams\', \'nba-teams\' ),
        \'not_found\'                  => __( \'Not Found\', \'nba-teams\' ),
        \'no_terms\'                   => __( \'No Nba Teams\', \'nba-teams\' ),
        \'items_list\'                 => __( \'Nba Teams list\', \'nba-teams\' ),
        \'items_list_navigation\'      => __( \'Nba Teams list navigation\', \'nba-teams\' ),
    );
    $rewrite = array(

    );
    $args = array(

        \'hierarchical\'               => false,

}
最后一部分register_new_terms_to_nbateam_taxonomy() 该函数仅适用于常用术语值（“name”、“slug”、“description”），但不适用于我添加的额外字段。

在您的情况下，“wp\\u insert\\u term”不会保存额外的自定义字段。

请尝试以下代码：

foreach ( $this->terms as $term_key=>$term) {
    // insert new terms in taxonomy
    wp_insert_term(
        $term[\'name\'],
        $this->taxonomy,
        array(
            \'slug\'          => $term[\'slug\'],
            \'description\'   => $term[\'description\']
        )
    );

    update_option( \'term_team_code_\' . $term[\'slug\'], $term[\'code\'] );
    update_option( \'term_team_nba_id_\' . $term[\'slug\'], $term[\'nba-id\'] );
    update_option( \'term_team_espn_id_\' . $term[\'slug\'], $term[\'espn-id\'] );
    update_option( \'term_team_color_\' . $term[\'slug\'], $term[\'color\'] );

    unset( $term );
}
