I stated to learn PHP. I really like it but now I have a problem:
With this code I make a html form.

<html>
<head><title>Test</title>
</head>
<body>
<form action=“act.php” method=“GET”>
<input type=“text” name=“name” value=“Name”>

<textarea name=“email” rows=“1” cols=“40”>eMail</textarea>

<input type=“submit” value=“Click me”>

</form>
</body>
</html>

If the person clicks on the button he comes to the act.php site. Here is the code for it:

<html>
<head>
<title></title>
</head>
<body>
<?php
print “Welcome $name\n\n”;
print “Your eMail is: $email”;
?>
</body>
</html>

When I want to view it with my browser it only says:

Welcome

Your eMail is:

Is that normal because in my book, I am learning from it doesn’t say what the browser should show.

Let me preface this by saying that I don’t know PHP, so take this with a rather large grain of salt.

Based upon the information here, I would guess that you either need to code your act.php file as:

<html>

<head>

<title></title>

</head>

<body>

<?php

print "Welcome <b>$HTTP_POST_VARS['name']</b><p>\n\n";

print "Your eMail is: <b>$HTTP_POST_VARS['email']</b>";

?>

</body>

</html>

... or the register_globals needs to be set to true in your server’s php.ini file to have your existing code work properly.

OK thanks, but how do I register the globals and shouldn’t they already be registered?
And yes, this code:

[color=darkblue]

<?php 

print "Welcome <b>$HTTP_POST_VARS['name']</b><p>\n\n"; 

print "Your eMail is: <b>$HTTP_POST_VARS['email']</b>"; 

?> 

[/color]

Can somebody who has PHP installed on his mac test this please, because maby I need to install my PHP again.

To be honest, I don’t have PHP installed on my Mac, but we do have it installed on the TMO server, of course, and I tested your scripts here. They work fine, of course, and generate the output that you would imagine. We do have register_globals enabled, though, so that’s likely it:

You’ll want to set this on in your php.ini file (check http://www.php.net/manual/fi/html/configuration.html and http://www.php.net/manual/fi/html/configuration.html#ini.register-globals) for information on how to do this. You’ll likely need to restart your web server once you make this change, and then all will be well.

One thing I noticed—they have you using “GET” as your post method. GET sends the variables in with the requesting URL, and it can get messy (especially if users cache the data and accidentally come back to it). A better way is to use POST as your method (method=“POST”). THis sends them in the header of the users’ requests, and makes it a lot cleaner.

Mhm, OK, have another problem which is that I can’t find the php.ini on my Mac. I searched with Sherlock but nothing like that was found and neither I was able to find it.

So, mhm. Ok, I am not (yet) very good with stuff like that on Mac.
Does anybody has any ideas or I am just to unable (<= I don’t know if you can say this like that in English, but let’s hope so) for that?

So, I still didn’t fix the stupid globals thing.

But I found out some stuff and have a few more questions:

<?php

phpinfo()

?> 

So this code up there list my much information about the php which is installed on my Computer and it says somewhere, wait let my copy, OK:
Configuration File (php.ini) Path /usr/local/lib
The stupid thing is that I cant find the usr/local/lib (=does this actually stand for user/local/Library. If so it’s bad because the php.ini is not there). I need to know where I can acctually find this php.ini because on an other line from the phpinfo thing it says:

Directive: register_globals
Local Value: Off
Master Value: Off

I thing these two Off things should be on On. Or?
Please I need help, I want to read on in my book. You may now thing Johannes is so dum, why doesn’t he just check in his book how to do this. I am not checking in my book because this nice people didn’t write how to do it on a mac.
