upload form file types....

Posted on 16th Feb 2014 by admin

Hey all, I am learning PHP and I am writing a script from the W3C Schools tutorials for uploading files to my server. I want to be able to use it for a friend to upload files to my server (I know to be careful). I only want it to be able to allow those images, exe, rar and zip files, no ISO's, .IMG's etc... I understand how the code works and have added and extra image file extension, but how would I add .exe, .zip and .rar? I thought maybe app/exe etc... and tried it, but I don't think it worked, files aren't being uploaded other than the images. All my permissions are set right and my test files sizes are ok.
What I am is asking is what is the code to allow those 3 file types to be uploaded?

Here is my code:
Code: <?php
if (((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/pjpeg")))
&& ($_FILES["file"]["size"] < 8000000))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
}
}
}
else
{
echo "Invalid file";
}
?>
