我有一个基本的图片上传工作很好但现在我需要将它保存在我的MySql DB 3图像中不仅一个，如何用我的上传脚本以相同的形式保存3个图像？
我需要保存3张图片，因为我的页面中有一篇文章博客，我想在预览中的滑块中显示3张图片，因此，我需要在相同的ID中保存3张图片。
另一个想法是，如何在没有上传脚本的情况下保存一两个显示错误，因为上传的一个或两个甚至三个文件都是空的？
我在这里向您展示我的上传脚本：
<?php
require_once("connection.php");
require_once("settings.php");
$alert = "";
if(isset($_FILES['foto_ser1'])) {
$extension = pathinfo($_FILES['foto_ser1']['name']);
$extension = $extension["extension"];
$allowed_paths = explode(", ", $allowed_ext);
$valid = 0;
for($i = 0; $i < count($allowed_paths); $i++) {
if ($allowed_paths[$i] == "$extension") {
$valid = 1;
}
}
if ($valid == 1 && $_FILES["foto_ser1"]["size"] <= $max_weight) {
if (file_exists("../assets/img/servicios/" . $_FILES["foto_ser1"]["name"])) {
$alert = '<p class="error">' . $_FILES["foto_ser1"]["name"] . ' El nombre del archivo ya existe!' . '</p>';
} else {
move_uploaded_file($_FILES["foto_ser1"]["tmp_name"], "../assets/img/servicios/" . $_FILES["foto_ser1"]["name"]);
$save1 = $_FILES["foto_ser1"]["name"];
$statement = $conn->prepare("INSERT INTO SERVICIOS (titulo, descripcion, categoria, foto_ser1, foto_ser2, foto_ser3) VALUES (?, ?, ?, ?, ?, ?)");
if ($statement->execute(array($_POST['titulo'],$_POST['descripcion'],$_POST['categoria'],$save1,$save2,$save3)));
$dbSuccess = true;
$alert = '<p class="ok">' . ' Servicio agregado satisfactoriamente!' . '</p>';
$dbh = null;
}
} else {
$alert = '<p class="error">' . ' Tipo de archivo inválido!' . '</p>';
}
}
?>
表单page.php：
<form class="form-horizontal" id="servicios" name="data" method="post" enctype="multipart/form-data">
<fieldset>
<?php echo $alert1; ?>
<div class="control-group">

修改
新代码：
<?php
require_once("includes/connection.php");
require_once("includes/settings.php");
$alert = "";
if(isset($_FILES['foto_ser{$i}'])) {
for($i = 1; $i <= 3; $i++) {
if ($_FILES["foto_ser{$i}"]['error'] === UPLOAD_ERR_OK) {
if ($valid == 1 && $_FILES["foto_ser{$i}"]["size"] <= $max_weight) {
if (file_exists("assets/img/servicios/" . $_FILES["foto_ser{$i}"]["name"])) {
$alert = '<div class="alert alert-block alert-danger fade in">

答案 0 :(得分：0)
您需要进行上传处理。现在你的代码就是假设所有上传都会成功。实际上，它假设绝不会上传。
简而言之，你需要这样的东西：
for ($i = 1; $i <= 3; $i++) {
if ($_FILES["foto_ser{$i}"]['error'] === UPLOAD_ERR_OK) {
...file #$i has succeeded...
}
}
您的代码也非常危险 - 您在['name']调用中直接使用用户提供的move_uploaded_files参数，这允许恶意用户在您的服务器上随意编写他们选择的文件
