WordPress wp_localize_script：JS脚本无法识别PHP变量

Question

我正在尝试通过子主题修改WordPress中的脚本（ ajaxcalls.js ）。我在子主题（ ajaxcalls_child.js ）中创建了该文件的副本。

我在 function.php 文件中添加了以下代码，以使旧的JS文件出队，使新的JS文件入队并传递变量 ajaxcalls_vars ajaxcalls_child.js使用哪个：

<?php

//made sure here that the action execute after all the other scripts are loaded
add_action('wp_enqueue_scripts', 'wpestate_load_child_scripts', 100);

function wpestate_load_child_scripts() {
    wp_dequeue_script('wpestate_ajaxcalls');

    wp_enqueue_script('ajaxcalls_child', get_stylesheet_directory_uri().'/js/ajaxcalls_child.js', array('jquery'),'1.0', true);

    wp_localize_script(‘ajaxcalls_child’, ‘ajaxcalls_vars’, array(
        'contact_name'     =>  esc_html__( 'Your Name','wprentals'),
        'contact_email'    =>  esc_html__( 'Your Email','wprentals'),
        'contact_phone'    =>  esc_html__( 'Your Phone','wprentals'),
        'contact_comment'  =>  esc_html__( 'Your Message','wprentals'),
        'adv_contact_name' =>  esc_html__( 'Your Name','wprentals'),
        'adv_email'        =>  esc_html__( 'Your Email','wprentals'),
        'adv_phone'        =>  esc_html__( 'Your Phone','wprentals'),
        'adv_comment'      =>  esc_html__( 'Your Message','wprentals'),
        'adv_search'       =>  esc_html__( 'Send Message','wprentals'),
        'admin_url'        =>  get_admin_url(),
        'login_redirect'   =>  $login_redirect,
        'login_loading'    =>  esc_html__( 'Sending user info, please wait...','wprentals'),
        'userid'           =>  $userID,
        'prop_featured'    =>  esc_html__( 'Property is featured','wprentals'),
        'no_prop_featured' =>  esc_html__( 'You have used all the "Featured" listings in your package.','wprentals'),
        'favorite'         =>  esc_html__( 'Favorite','wprentals').'<i class="fas fa-heart"></i>',
        'add_favorite'     =>  esc_html__( 'Add to Favorites','wprentals'),
        'remove_favorite'  =>  esc_html__( 'remove from favorites','wprentals'),
        'add_favorite_unit'=>  esc_html__( 'add to favorites','wprentals'),
        'saving'           =>  esc_html__( 'saving..','wprentals'),
        'sending'          =>  esc_html__( 'sending message..','wprentals'),
        'reserve'          =>  esc_html__( 'Reserve Period','wprentals'),
        'paypal'           =>  esc_html__( 'Connecting to Paypal! Please wait...','wprentals'),
        'stripecancel'     =>  esc_html__( 'subscription will be cancelled at the end of the current period','wprentals'),
        'max_month_no'     =>  intval   ( get_option('wp_estate_month_no_show','') ),
        'processing'       =>  esc_html__( 'processing..','wprentals'),
        'home'             =>  get_site_url(),
        'delete_account'   =>  esc_html__('Confirm your ACCOUNT DELETION request! Clicking the button below will result your account data will be deleted. This means you will no longer be able to login to your account and access your account information: My Profile, My Reservations, My bookings, Invoices. This operation CAN NOT BE REVERSED!','wprentals'),
        'adv_search_what_half' =>  $adv_search_what_half,
        'adv_search_how_half'  =>  $adv_search_how_half,
        'adv_search_type'      =>  $adv_search_type
    ));
}

现在，当我访问我的网站后，可以看到旧脚本已被新脚本替换，但是我在chrome控制台上看到，只要新脚本中有一个函数需要ajaxcalls_vars，就不会对其进行定义。

Chrome控制台上的错误

因此有新脚本，但是没有根据 ajaxcalls_child.js 定义我的变量 ajaxcalls_vars ，因此，我认为我尝试将变量传递给新脚本的方式。

在研究了类似的问题之后，我理解了其他类型的错误，并尝试将该代码改进为我上面共享的代码。但是仍然无法做到正确。

您在wp_localize_script(‘ajaxcalls_child’, ‘ajaxcalls_vars’, array(...中前两个参数周围的单引号不是真正的单引号。尝试删除它们，并替换为'字符wp_localize_script('ajaxcalls_child', 'ajaxcalls_vars', array(... 一旦这样做，该对象就可以在排队的脚本中使用（在xampp wp 5.0上进行了测试）
