PHP图片上传问题？

I have the following code [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 ((($_FILES["file"]["type"] == "image/gif")
    || ($_FILES["file"]["type"] == "image/jpeg")
    || ($_FILES["file"]["type"] == "image/jpg")
    || ($_FILES["file"]["type"] == "image/pjpeg")
    || ($_FILES["file"]["type"] == "image/x-png")
    || ($_FILES["file"]["type"] == "image/png"))
    && ($_FILES["file"]["size"] < 2097152)
    && in_array($extension, $allowedExts))
    {
    if ($_FILES["file"]["error"] > 0) {
        echo '<a class="title" href="./upload.php">' .$_FILES["file"]["error"]. '</a>';
    } else {
        echo "Upload: " . $filename . "<br>";
        echo "Type: " . $_FILES["file"]["type"] . "<br>";
        echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
        echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";
        if (!($stmt = $con->prepare("INSERT INTO `cat_images` (`title`,`path`) VALUES (?,?)")) || !is_object($stmt)) {
            die( "Error preparing: (" .$con->errno . ") " . $con->error);
        }
        $stmt->bind_param('ss', $type, $filename);
        if($stmt->execute()) {
            move_uploaded_file($_FILES["file"]["tmp_name"], "./assets/uploads" . $filename);
            echo "Stored in: " . "./assets/uploads/" . $filename . "<br />";
            echo '<a href="./">Home</a>';
        } else {
            echo 'SQL command could not be Executed, Contact a Staff Member';
            echo '<a href="./upload.php">Try Again</a>';
        }
        $stmt->close();
    }
    }
}
?>

I get no response from the page or server, so I don't know what the issue is. Do any of you know of the solution?

I am attempting to make an image upload form, but I don't get a response from the server for a website.

From the php documentation of the superglobal $_FILES you can read the following sentence:

An associative array of items uploaded to the current script via the HTTP POST method.

So you should change your method="get" to method="post" and retrieve your $_GET['type'] by using $_POST['type'].

i think problem is here...your code is...

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

replace it with following line

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

make sure all directory is exist that is /assets/uploads/
