我有几个人和我一起在一个网站上工作，他们需要使用一组非常简单的规则创建自定义分类术语；然而，他们似乎不知道如何做到这一点。所以，我试图创建一个某种过滤器，它会自动将它们的值替换为正确的值。例如，他们应该是这样的：

[name] -> UTA_1234 // type of training + _ + post id of training
[slug] -> uta_1234 // which should be automatic if left blank
[description] -> 1234 // just the post id

看起来很简单，对吧？嗯，他们一直把它们改成小写，用破折号代替下划线，忘记添加描述(

因此，以下是我试图做的不起作用的事情：

/**
 * \'codes\' is the taxonomy slug
 */
add_action( \'created_codes\', \'eri_created_incorrect_access_id\', 10, 2 );
function eri_created_incorrect_access_id( $term_id, $tt_id ) {
    // Catch the term info
    $name = $_POST[\'name\'];
    $slug = $_POST[\'slug\'];
    $desc = isset($_POST[\'description\']) ?? \'\';

    // Replace dashes with underscores, and make name uppercase
    $name = strtoupper(str_replace(\'-\', \'_\', $name));
    $slug = str_replace(\'-\', \'_\', $slug);

    // Check if there is a description
    if (!$desc || $desc == \'\') {

        // Then we split the name and add the post id to the description
        $split_name = explode(\'_\', $name);
        $desc = $split_name[1];
    }

    // Now add the items
    add_term_meta( $term_id, \'name\', $name, true );
    add_term_meta( $term_id, \'slug\', $slug, true );
    add_term_meta( $term_id, \'description\', $desc, true );
}

相同的概念适用于其他自定义字段，但不适用于默认字段

wp_update_term( $term_id, \'codes\', [
    \'name\'        => $name,
    \'slug\'        => $slug,
    \'description\' => $desc,
] );

$term = get_term( $term_id );

// Catch the term info
$name = $term->name;
$slug = $term->slug;
$desc = $term->description;
