PHP没有插入错误

Question

我试图弄清楚为什么这段代码有时会插入，而其他时候却不会插入。没有错误消息或错误日志。

代码逻辑是，如果电子邮件记录在电子邮件表中，那么它将获得id并插入到customer表中。如果找不到电子邮件，则会将其插入电子邮件表，然后插入客户。

<?php

/* Default */

$terms               =  $_POST['terms'];
$ipAddress        = $_SERVER['REMOTE_ADDR'];

/* Database conections */

include 'config.php';

try
{
    $conn   =   new PDO('mysql:host=localhost;dbname='.$config['dataBaseName'], $config['userName'], $config['password']);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch (PDOException $e)
{
    echo 'Connection failded' . $e->getMessage();
}


/* Post data */


if (isset($_POST["firstName"]))
{
       $firstName = trim(ucfirst($_POST["firstName"]));
}

if (isset($_POST["email"]))
{
       $email = trim(ucfirst($_POST["email"]));
}

if (isset($_POST["postCode"]))
{
       $postCode = trim(strtoupper($_POST["postCode"]));
}

if (isset($_POST["url"]))
{
        $url      =  trim(ucfirst($_POST["url"]));
}
if (isset($_POST["terms"]))
{
        $terms     =  trim(ucfirst($_POST["terms"]));
}


/* Check if email is in database returns array */

try
{

echo 'Finding Email ->' .$email;

$stmt   = $conn->prepare("SELECT id,email FROM email WHERE email = :email");
$stmt->bindParam(':email',$email);
$stmt->execute();
$result = $stmt->fetch(PDO::FETCH_ASSOC);

}

catch (PDOException $e)

    echo 'Check if email is in table' . $e->getMessage();
