我想更改主题的核心文件。 我正在使用子主题，我想从我的functions.php更改我的核心文件功能。
这是一个核心文件函数：
// main blog drag and drop options
function cyberchimps_selected_elements() {
$options = array(
'boxes_lite' => __( 'Boxes Lite', 'cyberchimps_elements' ),
"portfolio_lite" => __( 'Portfolio Lite', 'cyberchimps_elements' ),
"blog_post_page" => __( 'Post Page', 'cyberchimps_elements' ),
"slider_lite" => __( 'Slider Lite', 'cyberchimps_elements' )
);
return $options;
}
add_filter( 'cyberchimps_elements_draganddrop_options', 'cyberchimps_selected_elements' );
现在，我只想在此代码中添加一行：
"box_lite" => __( 'box', 'cyberchimps_elements' ),
而这个：
require_once( $directory_path . '/elements/boxes2.php' );
有人可以帮助我吗？
有一个很棒的WordPress函数叫做remove_filter((。您可以使用它删除上述功能，然后在子主题的函数中重新添加修改后的版本.php。像这样：
remove_filter( 'cyberchimps_elements_draganddrop_options', 'cyberchimps_selected_elements' );
add_filter( 'cyberchimps_elements_draganddrop_options', 'cyberchimps_selected_elements_child' );
// main blog drag and drop options
function cyberchimps_selected_elements_child() {
$options = array(
"box_lite" => __( 'box', 'cyberchimps_elements' ),
"portfolio_lite" => __( 'Portfolio Lite', 'cyberchimps_elements' ),
"blog_post_page" => __( 'Post Page', 'cyberchimps_elements' ),
"slider_lite" => __( 'Slider Lite', 'cyberchimps_elements' )
);
return $options;
}
您可以按照
以下给定的代码应用一个参数变量，它肯定会起作用，只是您必须确保无论要检索更改的选项数组的任何地方，都必须传递参数值"false"。函数调用也写在代码下面。祝你好运...
// main blog drag and drop options
function cyberchimps_selected_elements($default=true) {
if($default){
$options = array(
"boxes_lite" => __( 'Boxes Lite', 'cyberchimps_elements' ),
"portfolio_lite" => __( 'Portfolio Lite', 'cyberchimps_elements' ),
"blog_post_page" => __( 'Post Page', 'cyberchimps_elements' ),
"slider_lite" => __( 'Slider Lite', 'cyberchimps_elements' )
);
} else {
$options = array(
"boxes_lite" => __( 'Boxes Lite', 'cyberchimps_elements' ),
"portfolio_lite" => __( 'Portfolio Lite', 'cyberchimps_elements' ),
"blog_post_page" => __( 'Post Page', 'cyberchimps_elements' ),
"slider_lite" => __( 'Slider Lite', 'cyberchimps_elements' ),
"box_lite" => __( 'box', 'cyberchimps_elements' )
);
}
return $options;
}
函数调用示例：
//function call
cyberchimps_selected_elements(false);
