php if语句在Internet Explorer中不起作用

Question

ie does not render my php if statement well, any ideas? I say this because it works well in firefox.

<input type="image" src="Images/submit.png" value="REGISTER" name="command" />

    if($_REQUEST['command'] == 'REGISTER'){
        print "test";
    }
    else{

    }

It is not printing "test"

Answer 1

PHP is executed server side; IE has no bearing on your if statement. My guess is that $_REQUEST['command'] is not being set.

What does this print:

if(empty($_REQUEST['command')) print 'command is empty';

Another idea would be to append the "command" data to your URL:

http://localhost/your-php-script.php?command=foo

EDIT Just noticed that you're using type="image", I don't know if IE supports that: http://www.codingforums.com/archive/index.php/t-79035.html, try using a regular submit button.
