如何在子函数文件中正确实现新的if语句？

时间：2018-08-19 作者：James

我想对父函数的if语句中的某个元进行一些更改。php文件，我通过child这样做。

以下是父代码片段：

if( !function_exists(\'adifier_custom_meta\') ){
function adifier_custom_meta(){

$meta_boxes = array();

$advert_details = array(

array(
        \'id\'                => \'advert_cond\',
        \'name\'              => esc_html__( \'Condition\', \'adifier\' ),
        \'type\'              => \'select\',
        \'options\'           => array(
            \'0\' => esc_html__( \'-Select-\', \'adifier\' ),
            \'1\' => esc_html__( \'New\', \'adifier\' ),
            \'2\' => esc_html__( \'Manufacturer Refurbished\', \'adifier\' ),
            \'3\' => esc_html__( \'Used\', \'adifier\' ),
            \'4\' => esc_html__( \'For Parts Or Not Working\', \'adifier\' ),
        ),
        \'values_callback\'   => \'adifier_get_advert_meta\',
        \'save_callback\'     => \'adifier_save_advert_meta\',          
        ),
    ),

return $meta_boxes;}

add_filter(\'cmb_meta_boxes\', \'adifier_custom_meta\'); }

The following below is the simple change i have made (See meta "new" changed to "new with tags" as with "used".

if( !function_exists(\'adifier_custom_meta\') ){
function adifier_custom_meta(){

$meta_boxes = array();

$advert_details = array(

array(
        \'id\'                => \'advert_cond\',
        \'name\'              => esc_html__( \'Condition\', \'adifier\' ),
        \'type\'              => \'select\',
        \'options\'           => array(
            \'0\' => esc_html__( \'-Select-\', \'adifier\' ),
            \'1\' => esc_html__( \'New with tags\', \'adifier\' ),
            \'2\' => esc_html__( \'Manufacturer Refurbished\', \'adifier\' ),
            \'3\' => esc_html__( \'Used with tags\', \'adifier\' ),
            \'4\' => esc_html__( \'For Parts Or Not Working\', \'adifier\' ),
        ),
        \'values_callback\'   => \'adifier_get_advert_meta\',
        \'save_callback\'     => \'adifier_save_advert_meta\',          
        ),
    ),

return $meta_boxes; }



add_filter(\'cmb_meta_boxes\', \'adifier_custom_meta\');
}

Completing this change is crashing my site. I am unsure as to why. Please see my full child functions.php code:

<?php
 add_action( \'wp_enqueue_scripts\', \'theme_enqueue_styles\', 12 );
 function theme_enqueue_styles() {
 wp_enqueue_style( \'parent-style\', get_template_directory_uri() . 
 \'/style.css\' ); }   

 if( !function_exists(\'adifier_custom_meta\') ){
 function adifier_custom_meta(){

$meta_boxes = array();

$advert_details = array(

array(
        \'id\'                => \'advert_cond\',
        \'name\'              => esc_html__( \'Condition\', \'adifier\' ),
        \'type\'              => \'select\',
        \'options\'           => array(
            \'0\' => esc_html__( \'-Select-\', \'adifier\' ),
            \'1\' => esc_html__( \'New with tags\', \'adifier\' ),
            \'2\' => esc_html__( \'Manufacturer Refurbished\', \'adifier\' ),
            \'3\' => esc_html__( \'Used with tags\', \'adifier\' ),
            \'4\' => esc_html__( \'For Parts Or Not Working\', \'adifier\' ),
        ),
        \'values_callback\'   => \'adifier_get_advert_meta\',
        \'save_callback\'     => \'adifier_save_advert_meta\',          
        ),
    ),

return $meta_boxes; }


add_filter(\'cmb_meta_boxes\', \'adifier_custom_meta\'); }
?>
我已经对网站周围其他区域的文件进行了所有其他必要的更改，绝对没有错误。例如，这是一个分类广告网站，当客户提交广告时，他们可以在广告创建期间选择产品是“带标签的新产品”还是“带标签的使用产品”。现在我想在广告元中显示选择，而不是原来的“新建”和“已使用”。

The below is the full array & the adifier_custom_meta() function from parent:

你把, 而不是; 结束时$advert_details. 如果您更好地缩进代码，您将更好地看到这种错误。

add_action(\'wp_enqueue_scripts\', \'theme_enqueue_styles\', 12);

function theme_enqueue_styles() {
    wp_enqueue_style(\'parent-style\', get_template_directory_uri() . \'/style.css\');
}

if (!function_exists(\'adifier_custom_meta\')) {

    function adifier_custom_meta() {

        $meta_boxes = array();

        $advert_details = array(
            array(
                \'id\'                => \'advert_cond\',
                \'name\'              => esc_html__( \'Condition\', \'adifier\' ),
                \'type\'              => \'select\',
                \'options\'           => array(
                    \'0\' => esc_html__( \'-Select-\', \'adifier\' ),
                    \'1\' => esc_html__( \'New with tags\', \'adifier\' ),
                    \'2\' => esc_html__( \'Manufacturer Refurbished\', \'adifier\' ),
                    \'3\' => esc_html__( \'Used with tags\', \'adifier\' ),
                    \'4\' => esc_html__( \'For Parts Or Not Working\', \'adifier\' ),
                ),
                \'values_callback\'   => \'adifier_get_advert_meta\',
                \'save_callback\'     => \'adifier_save_advert_meta\',          
            ),
        );

        return $meta_boxes;

    }

    add_filter(\'cmb_meta_boxes\', \'adifier_custom_meta\');

}
您还可以尝试使用具有语法分析功能的编辑器，如Eclipse PHP：
