OK, I got this homework assignment to do in php, I'm supposed to add to this code that they give me in the book.... strangely enough the code doesn't even work or I copied it wrong... either way, I can't spot the error and im going mad. Everything works except when I get to writing the file... It's due in a few hours, so the faster i receive help the faster my stress level goes down. :P
Thanks.

SendingRSVP.php

Code:

<html>
  <head>
    <title>RSVP</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  </head>
  <body>

<?php

if (empty($_GET['name']) || !isset($_GET['attendance']))
    echo "<p>You must enter your name and specify whether you will attend! Click your browser's Back button to return to the RSVP form.</p>";

else
    if($_GET['attendance'] == "yes" && !is_numeric($_GET['guests']))
        echo "<p>Please specify the number of guests who will accompany to the RSVP form.</p>";
    

else {
    if($_GET['attendance'] == "yes") {
        $YesFile = "attending.txt";
        
            if(file_put_contents($YesFile, addslashes($_GET['name']) . ", " . $_GET['guests'] . "\n", FILE_APPEND))
                echo "<p>Thanks for RSVP'ing! We're looking forward to seeing you!</p>";
            

else
    echo "<p>Cannot save to the $YesFile file.</p>";
    }

if($_GET['attendance'] == "no") {
    $NoFile = "notattending.txt";
    
    if(file_put_contents($NoFile, addslashes($_GET['name']) . "\n", FILE_APPEND))
        echo "<p>Thanks for RSVP'ing! Sorry you can't make it!</p>";

        else
            echo "<p>Cannot save to the $NoFile file.</p>";
 }
}
?>

At first glance I don't see any errors, are you getting an error message or warning (make sure error reporting is on)? Can you be more descriptive about your problems... Is the file not being written, not being written correctly?

No errors... See for yourself:
http://codingasylum.freehostia.com/practice/RSVP.html
I tried the function exit(); throughout my code and it wouldn't work where you see

Code:

            if(file_put_contents($YesFile, addslashes($_GET['name']) . ", " . $_GET['guests'] . "\n", FILE_APPEND))
                echo "<p>Thanks for RSVP'ing! We're looking forward to seeing you!</p>";

It seems like that call to file_put_contents if failing. Is error reporting on on your server? Try chmod'ing noattending.txt 755.

Also, your code was a bit difficult to read so I reorganized it:

PHP Code:


			
<html>

  <head>

    <title>RSVP</title>

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

  </head>

  <body>



<?php



if (empty($_GET['name']) || !isset($_GET['attendance']))

    echo "<p>You must enter your name and specify whether you will attend! Click your browser's Back button to return to the RSVP form.</p>";



else if($_GET['attendance'] == "yes" && !is_numeric($_GET['guests']))

        echo "<p>Please specify the number of guests who will accompany to the RSVP form.</p>";

    



else 

{

    if($_GET['attendance'] == "yes")

    {

        $YesFile = "attending.txt";

        if(file_put_contents($YesFile, addslashes($_GET['name']) . ", " . $_GET['guests'] . "\n", FILE_APPEND))

            echo "<p>Thanks for RSVP'ing! We're looking forward to seeing you!</p>";

        else

            echo "<p>Cannot save to the $YesFile file.</p>";

    }



    if($_GET['attendance'] == "no")

    {

        $NoFile = "notattending.txt";

        

        if(file_put_contents($NoFile, addslashes($_GET['name']) . "\n", FILE_APPEND))

            echo "<p>Thanks for RSVP'ing! Sorry you can't make it!</p>";

        else

            echo "<p>Cannot save to the $NoFile file.</p>";

    }

}

?>

</body>

</html>

by the way, for future reference...

Using double quotes (" ") causes PHP to attempted to parse that string, which isn't necessary if it does not contain a variable (ie "my var = $myVar"). Use single quotes (' ') for strings that don't need to be parsed.

This is the books code... not my code. Not that I'm a great programmer, but all that you see has not been edited by me. It's straight from the book onto my server and this forum. I changed the files permissions to 777... still wasn't working. I don't know if it's my server not supporting something or wtf is going on....

Maybe I'll just write all the code out and hope he doesn't upload it on his server to see if it works. lol.

With all due respect for your scholastic aspirations, while I'm sure plenty of people love to look at homework assignments, I personally come here to learn more about the leading edge of both web technologies, standards, and business practices. There are plenty of forums where you can get help with your homework, but "webmaster talk" does not seem to be the proper venue for study time.

I didn't notice any rule about only questions regarding "leading edge web technologies, standards and practices" being acceptable.

I think its a perfectly legitimate question, and there are plenty of people who arn't on the "leading edge" here (myself included).

Note that had he asked for someone to do his homework for him I wouldn't find his question acceptable. There's nothing wrong with asking for help picking out a bug, especially when you are new to something.

PHP is a leading edge web technology. Why does it matter if I'm writing php inside of class or outside of class? I do both, it just so happens I wanted some help with my assignment. My goal is to learn php and become good at it, which is why I attend class. This "webmaster talk" you speak of may include writing code in php. By the way web masters ALWAYS study, if you aren't, you become irrelevant. This forum is my second school... You just said yourself you were here to learn, I am as well... along with many, many other people...
