使用wp_INSERT_TERM()函数添加术语时，缺少Term_id和Term_Taxonomy_id

时间：2012-04-11 作者：Average Joe

检查线路；list（$term\\u id，$taxonomy\\u id）=$result在下面的代码段中。（朝向底部）。为什么我缺少术语\\u id&；当我回显$taxonomy\\u id的值时？它们不应该由wp\\u插入它们来填充吗？

$term_name = \'Uncategorized\';
$term_slug = sanitize_title(\'Uncategorized\', \'Default category slug\');
$term_taxonomy = \'category\';
$term_description = $term_slug . " desc here.. ";
$term_parentID = 0;

if ( is_term( $term_name , $term_taxonomy ) ):
    echo "this term exists!";
    die;
else:
    //echo "This terms does not exist!";
    //echo "<pre>";
    //global $wp_taxonomies;
    //print_r ($wp_taxonomies);
    //echo "</pre>";
    if (taxonomy_exists($term_taxonomy)):
        //insert the term into the wp_terms
        $args = array(
                            \'description\' => $term_description,
                            \'slug\' => $term_slug,
                            \'parent\' => $term_parentID 
                        );  

        $result = wp_insert_term($term_name, $term_taxonomy, $args);

        if ( is_wp_error( $result ) ):
            $error_string = $result->get_error_message();
            echo \'<div id="message" class="error"><p>\' . $error_string . \'</p> </div>\';
        else:
            list($term_id,$taxonomy_id) = $result;
            echo "<p>The term <i>{$term_name}</i> under the <i>{$term_taxonomy}</i> taxonomy has been added into the <i>wp_terms & wp_term_taxonomy<i> tables. The Term ID is {$term_id} and the related taxonomy ID is {$term_taxonomy_id}.";
            //outputs as The term Uncategorized under the category taxonomy has been added into the wp_terms & wp_term_taxonomy tables. The Term ID is and the related taxonomy ID is .
        endif;                          
    else:
        echo "<p>{$term_taxonomy} does not exist. we cannot add this $term. Please use the register_taxonomy function to register this taxonomy. ";
    endif;
endif;

问题是php函数的使用list. 如果成功，wp_insert_term 返回以下形式的内容：

array(2) { ["term_id"]=> int(307) ["term_taxonomy_id"]=> int(325) }
您不能使用list 将此作为list 仅适用于数字阵列。相反，请尝试extract 而是：

extract($result);
echo "<p>The term <i>{$term_name}</i> under the <i>{$term_taxonomy}</i> taxonomy has been added into the <i>wp_terms & wp_term_taxonomy<i> tables. The Term ID is {$term_id} and the related taxonomy ID is {$term_taxonomy_id}.";

//------get term/taxonomy data

Taxonomy Checkbox Admin Panel

我有一个基本的管理面板，允许管理员使用复选框保存选项。复选框的使用是因为该选项需要多选因此，管理选项-复选框1-复选框2-复选框3等我的复选框是动态生成的，使用<input type=\"checkbox\" name=\"firm\" id=\"firm-<?php echo esc_attr( $term->slug ); ?>\" value=\"<?php echo esc_attr( $term->slug ); ?>\" <?php checke
