我正在使用CRUD开发PHP管理员管理页面。在此页面中，我们想通过使用包含用于插入和更新数据的表单的模式框来添加车辆并编辑SQL记录表中的数据。但是我有一个问题：
模式框未显示。但是我试图用一个可以正常工作的纯HTML和CSS模式框代替它。
纯模式框非常完美，但是在表格的编辑列中，只有第一行可以全部显示一个编辑模式，而另一行则没有模式。
完整的页面代码：
<?php
require_once '../inc/function.php';
adac();
require_once '../inc/db.php';
if(!empty($_POST)){
$requ = $pdo->prepare('INSERT INTO `vehicules`(`marques`, `modele`, `annee`, `proprio`, `imma`) VALUES (?, ?, ?, ?, ?)');
$rl= $requ->execute([$_POST['mq'], $_POST['ml'], $_POST['an'], $_POST['pro'], $_POST['im']]);
if($rl){
$_SESSION['flash']['success'] = "Informations enregistrées!";
}else{
$_SESSION['flash']['danger'] = "Echec!";
}
}
?>
