PHP图像上传器需要它很简单

Question

I need to get this done very quickly. What's an easy way to do image uploading in php...I have a script atm but if an image with the same name comes it'll overwrite it.

Basically I just want to be able to use the form field file to select an image and upload and maybe rename it somehow. Then put the location into a database to retrieve when needed.

Any tips or ideas on how to do this? Don't have a lot of time to get this done.

Sounds to me like you are looking for the easy way out. Please remember that we are not here to give you your code solution, but merely as an advisory panel to help you get over some obstacles in your current (already tried to make it work) code. If you read up a bit its real easy, thats the reason for documentation on everything, especially PHP and file uploading.

Seems to me right now, your script has a security issue as well.

Append a unique hash to the end of the filename before you save it. That way no one can overwrite your files.

Answer 3

Can you just append uniqid() to the filename..?

$target = "files/";

// Upload the file to directory
$url = basename($_FILES['uploadedfile']['name']);
$name = str_replace(' ', '_', $url);
$target .= strtolower($name . uniqid());

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target))
{
    echo 'File has been uploaded<br />
    <a href="' . $target . '">http://yoursite.com/directory/' . $target . '</a>';
}

Obviously still needs to be made more secure.
