所以，我的编码级别实际上等于零的前缀......

我正在使用带有 Wp All Import 插件的 Wordpress，并且我有这个代码来防止 wpallimport 创建新的类别/分类法等。

function dont_create_terms( $term_into, $tx_name ) {

// Check if term exists, checking both top-level and child
// taxonomy terms. 
$term = empty($term_into['parent']) ? term_exists( $term_into['name'], $tx_name, 0 ) : term_exists( $term_into['name'], $tx_name, $term_into['parent'] );

// Don't allow WP All Import to create the term if it doesn't
// already exist.
if ( empty($term) and !is_wp_error($term) ) { 
    return false;
}

// If the term already exists assign it.
return $term_into;

}

add_filter( 'pmxi_single_category', 'dont_create_terms', 10, 2 );

现在，如标题中所述，我必须仅针对某些分类法运行此代码...

我尝试了多种解决方案，最后我尝试添加这一行

   if ($tx_name == 'taxonomyname') {

像这儿

    function dont_create_terms( $term_into, $tx_name ) {
        
    // Check if term exists, checking both top-level and child
    // taxonomy terms. 
    $term = empty($term_into['parent']) ? term_exists( $term_into['name'], $tx_name, 0 ) : term_exists( $term_into['name'], $tx_name, $term_into['parent'] );

if ($tx_name == 'taxonomyname') {

    
    // Don't allow WP All Import to create the term if it doesn't
    // already exist.
    if ( empty($term) and !is_wp_error($term) ) { 
        return false;
    }

        // If the term already exists assign it.
        return $term_into;
    
    }

add_filter( 'pmxi_single_category', 'dont_create_terms', 10, 2 );

但每次都没有出现。

任何帮助都非常感谢，提前感谢大家

找到解决方案

function dont_create_terms( $term_into ) {
    

// Check if term exists, checking both top-level and child
// taxonomy terms. 
$term = empty($term_into['parent']) ? term_exists( $term_into['name'], $tx_name, 0 ) : term_exists( $term_into['name'], $tx_name, $term_into['parent'] );

    if ( $tx_name == 'taxonomy_name' ){

// Don't allow WP All Import to create the term if it doesn't
// already exist.
if ( empty($term) and !is_wp_error($term) ) { 
    return false;
}

    // If the term already exists assign it.
    return $term_into;


}

add_filter( 'pmxi_single_category', 'dont_create_terms', 10, 2 );

而不是调用函数：

[dont_create_terms({yourxmldata[1]})]

它仅适用于单个分类法，如果分类法包含多个值，它将不起作用

所以再次，如果您有任何建议，欢迎您
