Question

我有一个图片上传脚本，允许简单的PHP上传个人资料图片。它现在意外地失败上传。我不完全确定为什么。我检查了post_max_size和upload_max_size，它们超过1MB。我怀疑它与//删除上一张图片有关但不确定原因。如果你查看它所说的查询;

AND image1 !='../files/noprofile.jpg'

这样，如果配置文件图片是默认图片，则不会删除默认图片。我觉得这是与这部分有关，当图像是默认的个人资料图片时，上传失败。

我知道我应该使用mysqli，但请不要提到我正在研究它。

以下是整个脚本，为简单起见，我们采取了一些措施：

session_start();
$username=$_SESSION['username'];
$pass = $_SESSION['password']; 
$path = "../imageuploads/";

//Delete previous picture
$pic = mysql_query("
SELECT * FROM members WHERE artist='Y' AND username='$username' AND password='$pass' AND image1 !='../files/noprofile.jpg'
")or die(mysql_error());

 while($fetchpic = mysql_fetch_array($pic)){ 

//if image1 does not equal no profile
unlink( $fetchpic['image1']); 

}


$valid_formats = array("jpg", "png", "gif", "bmp", "jpeg");
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST")
    {
        $name = $_FILES['photoimg1']['name'];
        $size = $_FILES['photoimg1']['size'];

        if(strlen($name))
            {
                list($txt, $ext) = explode(".", $name);
                if(in_array($ext,$valid_formats))
                {
                if($size<(2024*2024))
                    {
                        $actual_image_name = time().substr(str_replace(" ", "_", $txt), 5).".".$ext;
                        $tmp = $_FILES['photoimg1']['tmp_name'];
                        if(move_uploaded_file($tmp, $path.$actual_image_name))
                            {
                            mysql_query("UPDATE members SET image1='../imageuploads/$actual_image_name' WHERE username='$username' AND password ='$pass' AND artist='Y'");

                                echo "<p1><img src='../imageuploads/".$actual_image_name."'  class='imageright1'></p1>";
                            }
                        else
                            echo "<p1>failed</p1>";
                    }
                    else
                    echo "<p1>Your image is a bit too big. It has to be below 1MB.</p1>";                   
                    }
                    else
                    echo "<p1>Only JPG, PNG GIF and BMP file formats are accepted.</p1>";   
            }

        else
            echo "<p1>You've gotta select an image first!</p1>";

        exit;
    }
