PHP上传文件，扩展错误

Question

我已经四处搜索并尝试了所有方法，我的脚本运行良好并且我正在正确上传文件，但现在我不知道为什么它仍然会抛出我的数组中确实存在的文件扩展名错误。

这是我的 PhpUpload 脚本：

<?php
# code...
if(!@include("bootstrap.php")) throw new Exception("Failed to include 'bootstrap'");
else{ 
    $sqldb=new SqlDB;
    $mysqli=$sqldb->DBconnect('localhost','root','root','dbex');
    if (isset($_GET['ref']) && isset($_GET['rooms']) && isset($_GET['showers']) && isset($_GET['parkings']) && isset($_GET['infos']) && isset($_GET['city']) && isset($_GET['surface']) && isset($_GET['price']) && isset($_GET['sup']) && isset($_GET['desc'])) {
        # code...
        if (!empty($_GET['ref']) && !empty($_GET['rooms']) && !empty($_GET['showers']) && !empty($_GET['parkings']) && !empty($_GET['infos']) && !empty($_GET['city']) && !empty($_GET['surface']) && !empty($_GET['price']) && !empty($_GET['sup']) && !empty($_GET['desc'])) {
            # code...
            $ref = $_GET['ref'];
            $rooms = $_GET['rooms'];
            $showers = $_GET['showers'];
            $parkings = $_GET['parkings'];
            $infos = $_GET['infos'];
            $city = $_GET['city'];
            $surface = $_GET['surface'];
            $price = $_GET['price'];
            $sup = $_GET['sup'];
            $desc = $_GET['desc'];

            //File size, path and extensions allowed
            $allowed_filetypes = array('.jpg','.jpeg','.png','.gif');
            $max_filesize = 10485760;
            $path="css/";

            //File name 
            $i=10;

            //File settings
            $filename = $_FILES['file']['name'];
            $uploadfile=$path.basename($filename);
            $ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);

            //Conditions
            if(!in_array($ext,$allowed_filetypes))
              die('The file you attempted to upload is not allowed.');
            if(filesize($_FILES['fileselect']['tmp_name']) > $max_filesize)
              die('The file you attempted to upload is too large.');
            if (file_exists($upload_path))
                die('File already exist.');
            if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) {
                # code...
                die('Line 41');
            }
            else{
                die('error uploading the file');
            }

        }
    }
}

?>

当我尝试上传我的数组中存在的带有“.gif”和“.jpg”扩展名的图像时，它说该文件是不允许的。

HTML 表单代码（Bootstrap CSS & Js）：

<form role="form" class="form-horizontal" enctype="multipart/form-data">
<div class="form-group has-feedback">
              <label class="control-label col-sm-3" for="fileselect">Images :</label>
              <div class="col-sm-9 upload">
                <!-- Change the wording using a title tag -->
                <input type="file" title="Parcourir..." name="file" multiple="multiple" id="file"/>
                <span class="messages" id="file-name"></span>
              </div>
            </div>
            <div class="form-group pull-right">
              <div class="col-sm-9">
                  <button type="submit" class="btn btn-success" id="submit" name="submit" value="addPro">Ajouter ce bien</button>
              </div>

</div>
</form>

谢谢你们！

Answer 1

form标签需要enctype="multipart/form-data"上传文件需要这个标签

编辑 为什么不将允许的文件类型数组更改为：array('image/jpg', 'image/jpeg', 'image/png', 'image/gif');

然后说：

$file_type = $_FILES['file']['type'];

if(!in_array($file_type, $allowed_filetypes)) {
 die('The file you attempted to upload is not allowed.');
}

这应该有效（至少对我有用）

问题已解决，我所做的是我删除了包含我的bootstrap.php 的条件 然后我的脚本在POST 方法上运行良好。

if (isset($_POST['ref']) && isset($_POST['rooms']) && isset($_POST['showers']) && isset($_POST['parkings']) && isset($_POST['location']) && isset($_POST['typepr']) && isset($_POST['tran']) && isset($_POST['priceper']) && isset($_POST['city']) && isset($_POST['surface']) && isset($_POST['price']) && isset($_POST['sup']) && isset($_POST['desc'])) {
        # code...
        if (!empty($_POST['ref']) && !empty($_POST['rooms']) && !empty($_POST['showers']) && !empty($_POST['parkings']) && !empty($_POST['location']) && !empty($_POST['typepr']) && !empty($_POST['tran']) && !empty($_POST['priceper']) && !empty($_POST['city']) && !empty($_POST['surface']) && !empty($_POST['price']) && !empty($_POST['sup']) && !empty($_POST['desc'])) {
            # code...
            $ref = $_POST['ref'];
            $rooms = $_POST['rooms'];
            $showers = $_POST['showers'];
            $parkings = $_POST['parkings'];
            $location = $_POST['location'];
            $typepr = $_POST['typepr'];
            $tran = $_POST['tran'];
            $priceper = $_POST['priceper'];
            $city = $_POST['city'];
            $surface = $_POST['surface'];
            $price = $_POST['price'];
            $sup = $_POST['sup'];
            $desc = $_POST['desc'];

            //File size, path and extensions allowed
            $allowed_filetypes = array('.jpg', '.jpeg', '.png', '.gif');
            $file_type = $_FILES['fileselect']['type'];
            $max_filesize = 10485760;
            $path="css/";

            //File name 
            $i=10;

            //File settings
            $filename = $_FILES['fileselect']['name'];
            $uploadfile=$path.basename($filename);
            $ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);

            //Conditions
            if(!in_array($ext,$allowed_filetypes))
              die('The file you attempted to upload is not allowed.');
            if(filesize($_FILES['fileselect']['tmp_name']) > $max_filesize)
              die('The file you attempted to upload is too large.');
            if (file_exists($uploadfile))
                die('File already exist.');
            if (move_uploaded_file($_FILES['fileselect']['tmp_name'], $uploadfile)) {
                # code...
                die('Line 41');
            }
            else{
                die('error uploading the file');
            }

        }
    }

我的html代码是一样的，希望我能帮助到这里的人，祝你好运
