Question

我有以下代码 [x]：

    <form action="#" method="get" enctype="multipart/form-data">
    <label for="file">Filename:</label><br />
    <input type="text" name="type" placeholder="Type"><br />
    <input type="file" name="file"><br />
    <input type="submit" name="submit" value="Submit">
    </form>
<?
if($_GET['type']!="") {
    $type = $_GET['type'];
    $allowedExts = array("gif", "jpeg", "jpg", "png");
    if($_FILES["file"]["type"] == "image/gif") {
        $encryptfile = md5(substr($_FILES["file"]["name"], 0, -4));
        $filename = $encryptfile. ".gif";
    } else if($_FILES["file"]["type"] == "image/jpeg") {
        $encryptfile = md5(substr($_FILES["file"]["name"], 0, -5));
        $filename = $encryptfile. ".jpeg";
    } else if($_FILES["file"]["type"] == "image/jpg") {
        $encryptfile = md5(substr($_FILES["file"]["name"], 0, -4));
        $filename = $encryptfile. ".jpg";
    } else if($_FILES["file"]["type"] == "image/pjpeg") {
        $encryptfile = md5(substr($_FILES["file"]["name"], 0, -6));
        $filename = $encryptfile. ".pjpeg";
    } else if($_FILES["file"]["type"] == "image/x-png") {
        $encryptfile = md5(substr($_FILES["file"]["name"], 0, -6));
        $filename = $encryptfile. ".x-png";
    } else if($_FILES["file"]["type"] == "image/png") {
        $encryptfile = md5(substr($_FILES["file"]["name"], 0, -4));
        $filename = $encryptfile. ".png";
    }
    $temp = explode(".", $filename);
    $extension = end($temp);
    if ((($_FILES["file"]["type"] == "image/gif")

    } else {

    }
    }
}
?>

我没有收到来自页面或服务器的回复，所以我不知道问题是什么。你们中的任何人都知道解决方案吗？

我正在尝试制作图片上传表单，但我没有收到服务器对网站的回复。

Answer 1

从超级全球$_FILES的php文档中，您可以阅读以下句子：

通过HTTP POST方法上传到当前脚本的关联项目数组。

因此，您应该将method="get"更改为method="post"并使用$_GET['type']检索$_POST['type']。

Answer 2

我认为问题在这里......你的代码是......

 move_uploaded_file($_FILES["file"]["tmp_name"], "./assets/uploads" . $filename);

将其替换为以下行

 move_uploaded_file($_FILES["file"]["tmp_name"], "/assets/uploads/".$filename);

确保所有目录都存在/ assets / uploads /
