通过url将参数从c＃表单发送到php

Question

I want to send a parameter that is asked to the user in a C# form and send it to php page. I also want that php page to open when user clicks a button. I have tried the following: string fid = textBox1.Text;

        ProcessStartInfo p1 = new ProcessStartInfo("https://localhost/filter/abc.php?id=fid");
        Process.Start(p1); 
    }
 echo $_GET['id'];//in php page

No variable value is getting passed.I mean on the php page when i print using echo I get fid. Not the value in fid, but the word 'fid' is printed. I have tried changing the parameter to id=123 and 123 is getting passed. I have also initialized fid to 123 like string fid=123; Again i get 'fid' as output.Please help

Answer 1

That's because you are sending the string literal fid not the variable contents. You could do this:

ProcessStartInfo p1 = new ProcessStartInfo("https://localhost/filter/abc.php?id=" + fid);

Which would use the variable fid. I would have some validation on the Textbox to ensure you don't suffer from XSS attacks.
