在wp admin/includes/media中。php我发现：

function media_buttons($editor_id = \'content\') {
    $context = apply_filters(\'media_buttons_context\', __(\'Upload/Insert %s\'));

    $img = \'<img src="\' . esc_url( admin_url( \'images/media-button.png?ver=20111005\' ) ) . \'" width="15" height="15" />\';

    echo \'<a href="\' . esc_url( get_upload_iframe_src() ) . \'" class="thickbox add_media" id="\' . esc_attr( $editor_id ) . \'-add_media" title="\' . esc_attr__( \'Add Media\' ) . \'" onclick="return false;">\' . sprintf( $context, $img ) . \'</a>\';
}
add_action( \'media_buttons\', \'media_buttons\' );

我不知道我正在做什么来更改函数中上载/插入的文本。php文件。我试过下面的方法，但没有效果。

function adcp_change_media_button($context) {
    return str_replace(\'Upload/Insert %s\', \'Upload/Insert images, documents, etc %s\');
}
add_filter(\'media_buttons\', \'adcp_change_media_button\');

谢谢你的帮助！

function adcp_change_media_button( $context ) 
{
    // $context acutally IS \'Upload/Insert %s\', so we simply drop in in some other string
    return __( \'Upload/Insert images, documents, etc %s\', \'YOUR_TEXTDOMAIN\' );
}
// Then use the right filter name
add_filter( \'media_buttons_context\', \'adcp_change_media_button\' );
