Question

我有以下代码在服务器文件夹上传图像，但问题是它即使我正在上传正确格式的图像也会发送格式信息我得到的错误是

 Sorry, only JPG, JPEG, PNG & GIF files are allowed

即使图像是jpg / jpeg / png / gif格式

我正在使用的代码是

<?php    
if ($_SERVER["REQUEST_METHOD"] == "POST") 
        {
            $target_dir = "profileimg/";
            $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
            $uploadOk = 1;
            $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
            // Check if image file is a actual image or fake image
            if(isset($_POST["submit"])) 
                {
                    if($check !== false) 
                        {
                            //echo "File is an image - " . $check["mime"] . ".";
                            $uploadOk = 1;
                        }
                    else 
                        {
                            echo "File is not an image.";
                            $uploadOk = 0;
                        }
                }

            // Check file size
            if ($_FILES["fileToUpload"]["size"] > 500000) 
                {
                    echo "Sorry, your file is too large.";
                    $uploadOk = 0;
                }

            // Allow certain file formats
            if($imageFileType != "jpg" || $imageFileType != "png" || $imageFileType != "jpeg" || $imageFileType != "gif" ) 
                {
                    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
                    $uploadOk = 0;
                }

            // Check if $uploadOk is set to 0 by an error
            if ($uploadOk == 0) 
                {
                    echo "Sorry, your file was not uploaded.";
                    // if everything is ok, try to upload file
                }
            else 
                {
                    $new_filename = $target_dir . uniqid() . '.' . $imageFileType;
                    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $new_filename))
                        {   
                            echo $new_filename;

                        }
                }
        }
?>
    <form  role="form" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" method="POST" enctype="multipart/form-data">
        <input type="file" class="form-control" id="input01" name="fileToUpload" 
        <button>Submit Form</button>
    </form>

任何人都可以正确修改代码

Answer 1

您的表单标记需要$(document).ready(function(){ $("button").click(function(){ $(".menu-ul").slideToggle("slow") }); });才能上传文件

如此改变

enctype="multipart/form-data">

要

<form  role="form" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" method="POST">

否则您的<form role="form" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" method="POST" enctype="multipart/form-data">变量为空

将您的验证更改为

$_FILES

Answer 2

Sorry, only JPG, JPEG, PNG & GIF files are allowed

你只检查jpg和所有但不是JPG或Jpg

检查您的文件有什么样的豁免权。放

 strtolower($imageFileType)
