php - 未捕获的 ArgumentCountError：函数 wpdb::prepare():update 的参数太少

问题描述

我收到以下错误：

致命错误：未捕获的 ArgumentCountError：函数 wpdb::prepare() 的参数太少，第 108 行的 /homepages/39/d740877019/htdocs/test/wp-content/themes/eduma/formulaire_get.php 中传递了 1 个，而预期的正好是 2 个在 /homepages/39/d740877019/htdocs/test/wp-includes/wp-db.php:1222 堆栈跟踪：#0 /homepages/39/d740877019/htdocs/test/wp-content/themes/eduma/formulaire_get.php (108): wpdb->prepare('UPDATE wp_pmpro...') #1 /homepages/39/d740877019/htdocs/test/wp-includes/template.php(688): require_once('/homepages/39/d ...') #2 /homepages/39/d740877019/htdocs/test/wp-content/themes/eduma/wrapper.php(14): load_template('/homepages/39/d...') #3 / homepages/39/d740877019/htdocs/test/wp-includes/template-loader.php(74): include('/homepages/39/d...') #4 /homepages/39/d740877019/htdocs/test/wp-blog-header.php(19): require_once('/homepages/39/d...') #5 /homepages/39/d740877019/htdocs/ test/index.php(17): require('/homepages/39/d...') #6 {main} 抛出 /homepages/39/d740877019/htdocs/test/wp-includes/wp-db.php在线 1222

有问题的行是下面的第二行：

$current_price = (($ecoles * $classes)/10)*28 ; 
$wpdb->query($wpdb->prepare("UPDATE wp_pmpro_membership_levels SET initial_payment='".$current_price."' WHERE name = mairie"));

解决方案

我解决了我的问题：

$current_price = (($ecoles * $classes)/10)*28 ; 
$wpdb->query($wpdb->prepare("UPDATE wp_pmpro_membership_levels 
                SET initial_payment='%s' 
                WHERE name = %s",$current_price,'mairie'));
