[PHP] self processing forms
I am using the O'Reilly Programming PHP manual, and have copied the code
from Example 7.3, p. 166. I have the magic_quotes_gpc set to ON in php.ini
(though toggling between on and off doesn't seem to have any effect). My
processed form reports 0.00F is -17.78C regardless of the initial
fahrenheit temperature I enter. Moreover, using another version of this
script, as shown in Example 7.4, p. 167, simply clears the text field, and
never returns an output. I can't figure out why I am not getting a correct
output - perhaps something in my php.ini file? A copy of the code I am using
(Example 7.3) is as follows:
!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.0 Transitional//EN
html
head
titleUntitled/title
/head
body
?php
if ($_SERVER['REQUEST_METHOD'] == 'GET'){
?
form action=?php echo $_SERVER['PHP_SELF'] ? method=POST
Fahrenheit temperature:
input type=text name=fahrenheit' /
input type=submit name=Convert to Celsius! /
/form
?php
} elseif ($_SERVER['REQUEST_METHOD'] == 'POST') {
$fahr=$_POST['fahrenheit'];
$celsius=($fahr - 32) * 5/9;
printf(%.2fF is %.2fC, $fahr, $celsius);
//echo The temperature in degrees celsius is $celsius;
} else {
die(This script only works with GET and POST requests.);
}
?
/body
/html

Thanks much in advance, Bill

Re: [PHP] self processing forms
Are you restarting Apache (or whatever webserver you're using) between
edits to php.ini? I assume since you also posted this to php-win that
you're using Win32. This would be my first step if you haven't done so
already.
I got corrected on this before, saying that you -don't- have to restart
between edits, but trust me, you do. I made changes to php.ini, saved,
and no changes were noted until AFTER I restarted Apache. Apache does
parse php.ini on startup because I entered invalid pathnames in various
places as a test, and only on restart did I get a notice that the
pathnames were invalid.
I'm using Win32, PHP v4.1.2 as a module (not CGI), Apache 1.3.something.

See below. I have the magic_quotes_gpc set to ON in php.ini (though toggling between on and off doesn't seem to have any effect). Because you'll only see a difference if your submission has something in it that needs to be escaped. For example ' will have slashes added to them. input type=text name=fahrenheit' / That needs to be a not a ' ---^ Also, notice there's no value attribute, so that's why you found in your other script that this field gets cleared out all the time. input type=submit name=Convert to Celsius! / By the way, allow me to point something out that doesn't have anything to do with your script not working, but may come in helpful in the future. You mean value not name. Name is what the name of the variable becomes. Value is the data that the variable holds and what's visible when you look at the form in your web browser. I suspect the button is supposed to say Convert to Celsius! in it rather than the default Submit Query.
