Question

我制作了一个PHP应用程序，可以将图片上传到服务器。大多数时候它工作正常，但它不会上传一些图片。

在这里，您可以下载所有文件，包括一张有用的图片和一张没有的图片：https://drive.google.com/file/d/0BwoIBS8cNsz4Rjl0eERMb2FndUk/view?usp=sharing

这是我的PHP代码（文件名：upload.php）：

<?php
    if(isset($_POST["submit"])) {
        $target_dir = "slike/";
        $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
        $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
        if($check !== false) {
            echo "File is an image - " . $check["mime"] . ".";
            $uploadOk = 1;
        } else {
            echo "File is not an image.";
            $uploadOk = 0;
        }
        // Check if file already exists
        if (file_exists($target_file)) {
            echo "Sorry, file already exists.";
            $uploadOk = 0;
        }
        // Check file size
        if ($_FILES["fileToUpload"]["size"] > 5000000) {
            echo "Sorry, your file is too large.";
            $uploadOk = 0;
        }
        // Allow certain file formats
        if($imageFileType != "jpg" && $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 {
            if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
                echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
            } else {
                echo "Sorry, there was an error uploading your file.";
            }
        }
    }
    else{
        echo "Sorry, there was an error uploading your file.";
    }

?>

这是我的HTML代码（文件名：index.php）：

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload" required>
    <input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html>

我在Windows 8上使用Wamp服务器，但我没有更改任何配置。

（英语不是我的母语，我希望得到更多关于代码的答案作为语法修正。）

Answer 1

Upload ImageFile is an image - image/jpeg.Sorry, your file is too large.Sorry, your file was not uploaded. - （5000000/1024 * 2）限制为4.7 MB

这一个不工作.jpg：错误=＆gt; $_FILES["fileToUpload"]["size"] > 5000000图片大小约为8 Mb

将{{1}}更改为更高的

Answer 2

我知道这个回应有点过期了。但是对于其他可能遇到类似错误的人。我最近遇到了类似的问题。所以我将5000000（十进制）更改为5242880（二进制），它的作用就像MAGIC。

我无法使用PHP
