我正在尝试使用wp_localize_script() 将一些php值发送到脚本。

以下是文件的一部分inc/show-event.php.

if( $price ) {
    $pricefortwo    = ceil( ( 2 * $price) - ( 0.2 * $price ) );
    $savefortwo     = ( 2 * $price) - $pricefortwo;
    $priceforthree  = ceil( ( 3 * $price) - ( 0.333 * $price ) );
    $saveforthree   = ( 3 * $price) - $priceforthree;
    $priceforretake = ceil( 0.5 * $price );
    $saveforretake  = $price - $priceforretake;

    // Setting the session variables
    $_SESSION[\'price\'] = $price;
    $_SESSION[\'price_for_two\'] = $pricefortwo;
    $_SESSION[\'price_for_three\'] = $priceforthree;
    $_SESSION[\'price_for_retake\'] = $priceforretake;

    $session_array = array(
                \'price\'         => $_SESSION[\'price\'],
                \'price_for_two\'     => $_SESSION[\'price_for_two\'],
                \'price_for_three\'   => $_SESSION[\'price_for_three\'],
                \'price_for_retake\'  => $_SESSION[\'price_for_retake\']
            );
    wp_localize_script( \'init_show_calendar\', \'session_param\', $session_array );
}

在此之后，当我尝试使用对象名称时session_param 在里面init_show_calendar.js 它抛出一个js错误session_param 未定义。但是当我在中使用以下代码时functions.php.

$session_array = array(
                \'price\'         => $_SESSION[\'price\'],
                \'price_for_two\'     => $_SESSION[\'price_for_two\'],
                \'price_for_three\'   => $_SESSION[\'price_for_three\'],
                \'price_for_retake\'  => $_SESSION[\'price_for_retake\']
            );
wp_localize_script( \'init_show_calendar\', \'session_param\', $session_array );

它返回变量，但不返回最新的值，它返回存储在页面刷新中的值。

仅供参考：Theshow-event.php 在插件中按以下方式调用

add_action(\'wp_ajax_get_event\', array($this, \'render_frontend_modal\'));
function render_frontend_modal() {
    require_once AEC_PATH . \'inc/show-event.php\';
}

如果你想了解更多信息，请告诉我。

 $output = array(
        \'price\'         => $_SESSION[\'price\'],
        \'price_for_two\'     => $_SESSION[\'price_for_two\'],
        \'price_for_three\'   => $_SESSION[\'price_for_three\'],
        \'price_for_retake\'  => $_SESSION[\'price_for_retake\']
    );
    $this->json_encode( $output );

// Setting the session value for the prices.
jQuery.session.set(\'price\', data.price);
jQuery.session.set(\'price_for_two\', data.price_for_two);
jQuery.session.set(\'price_for_three\', data.price_for_three);
jQuery.session.set(\'price_for_retake\', data.price_for_retake);
