Question

我需要从多个表中获取所有数据，而当我只做fetch()时，它只给我表中的最后一行。当我做fetchAll()时，它给我一个错误消息：

'注意：未定义索引：prix输入 109'行上的C：\ wamp64 \ www \ lecoq \ admin \ facture.php'

fetchAll(PDO::FETCH_COLUMN|PDO::FETCH_GROUP)

这是我的代码：

<?php 
include'header.php';
include'db/connexion.php';
session_start();
if (isset($_SESSION['login'])) {
  $login=$_SESSION['login'];
}else{
  header('location:index.php');
}

$ID=$_GET['ID'];

$sql = "SELECT * FROM customers  Where ID=$ID ";

$sql2 = "SELECT * FROM reservation_client ";

$sql3 = "SELECT * FROM facture Where id_client=$ID ";

$req = $bdd->prepare($sql);
$donnees = $req->fetch();

$req2 = $bdd->prepare($sql2);
$donnees2 = $req2->fetch();

$req3 = $bdd->prepare($sql3);
$donnees3 = $req3->fetch();

$req->execute();

$req2->execute();

$req3->execute();

Answer 1

$donnees3['prix']在该特定迭代中不存在，因此您会遇到该错误。

正确的处理方式是使用isset($donnees3['prix'])并在将其打印到页面之前检查它是否存在。

例如；改变这个：

print "<td>".$donnees3['prix']."</td>";

到

if(isset($donnees3['prix'])){
    print "<td>".$donnees3['prix']."</td>";
}else{
    print "<td>&nbsp;</td>";
}

最好是找出为什么找不到“ prix”的原因。

注意：当我fetchAll时未定义的索引
