Level of Difficulty : Beginner
Requirements : PHP

This tutorial will cover how to make a basic PHP upload script. You can easily convert or change it.

You need a PHP enabled host, the ability to upload, and HTML or PHP knowledge to change the script around to fit your needs

This is the basic code:

HTML

<form enctype="multipart/form-data" action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="2048000">
File: <input name="userfile" type="file" /><br />
<input type="submit" value="Upload" />
</form>

<?php
if (@is_uploaded_file($_FILES["userfile"]["tmp_name"])) {
copy($_FILES["userfile"]["tmp_name"], "/images/" . $_FILES["userfile"]["name"]);
echo "<p>File uploaded successfully.</p>";
}
?>

You can change the "/images/" to any directory you want.

You may also want to password protect the file. This is so only webmasters or selected people can view it.

[mod edit] Made a litttle change to the code to rid it of error. --hotsnoj

Question about $_SERVER['PHP_SELF'].

What would be the effect with it or without it in the form?

Thanks

It just means that you don't have to edit the "action" attribute to reflect the name you give the file.

First,

Thank you very very much for this simple and very useful uploading code.
I've tried it and had take of the $ before the /images/ folder to make it work. It shoes an error while it's there.

I have some other questions regarding this.
What if I want to update the image that I've already uploaded?
If I want to write the inage path in the data base, is this easy to do?
What if I want to have multible image uplaods in one page?

Thanks in advance

1. Just add an if block in there to check if said file exists and if it's last modified time is different than the one being uploaded.

2. The path is defined in the second part of the copy() function. You can find it there.

3. I'm not sure of the structure of the $_FILES array when there are multiples, but it should be easy to make this code into a loop to go through them all.

Did you create the directory? If yes, then you need to CHMOD the directory to 777.
