I have uploaded files in a server and when click the link for a file, it download the file automatically. But i want to give permission to download that file only for logged users. Please give me some example code for how to do that from PHP.. Thank you !
Re: download fiels
Presumably you have a variable detecting whether or not the user is logged in...
At the top of your page, before you include any html put something like
At the top of your page, before you include any html put something like
Code: Select all
[php]if (logged_in == true)//check the user is logged in
{//if they are...
$application = file_get_contents('http://mysite.com/application.exe');//place the contents of the exe file into the application variable
header("content-type:application/exe");//Tell the browser that its an exe file with a HTTP header
echo $application; //output the contents of the application variable (basically, output the exe to the browser)
}
else //if the user isn't logged in
{
die ("User is not logged in."); //appropriate error or whatever here
