[SOLVED] Checking File Types

[supanoob]

Hey, im using an upload script i found and am wanting to mod it to check file type and size. I was wondering if you could tell me how to do this?

 

This is the code i have, and i want it to check make sure the it is a jpeg, jpg or gif and less than 25KB in size.

<?php

if ($_GET['action'] == 'uploaded')
{

// Your file name you are uploading
$file_name = $HTTP_POST_FILES['ufile']['name'];

// random 4 digit to add to our file name
// some people use date and time in stead of random digit
$random_digit=rand(0000,9999);

//combine random digit to you file name to create new file name
//use dot (.) to combile these two variables

$new_file_name=$random_digit.$file_name;

//set where you want to store files
//in this example we keep file in folder upload
//$new_file_name = new upload file name
//for example upload file name cartoon.gif . $path will be upload/cartoon.gif
$path= "images/characters/".$new_file_name;
if($ufile !=none)
{
if(copy($HTTP_POST_FILES['ufile']['tmp_name'], $path))
{

echo "Successful<BR/>";
//$new_file_name = new file name
//$HTTP_POST_FILES['ufile']['size'] = file size
//$HTTP_POST_FILES['ufile']['type'] = type of file
echo "File Name :".$new_file_name."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size']."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type']."<BR/>";


}
else
{
echo "Error";
}
}

}

?>

thats script looks kinda old but to add filesize check

change

if($ufile !=none)

to

if($ufile !=none && $HTTP_POST_FILES['ufile']['size'] < 25000)

im using

 

PHP version 5.2.3

In that case you'll want to change each instance of $HTTP_POST_FILES to $_FILES for a start.  Then as MadTechie says, you can use $_FILES['ufile']['size'] to get the size.

 

As for how you want to chose the file type, this can be either by extension or mime type.

Yes actually, a search of these forums proved really fruitful.  Give it a try, and if you don't have any luck then post back.
