Basic question about incuding files and funcitons

[Jimmy Clay]

I have a very basic question about how to include files to be used by
another file. I'm trying to include a bad word filter into the guestmap on
my website. I know almost nothing about PHP code. I've tried everything I
can think of but I keep getting error messages. The bad word filter code I
found else where is this:
File name is badwords.php

<?php
//* Check.php */

function check( ) /* Establishes the function check */
{

global $message; /* Gets All Variables */

//To Add New Words, Just Copy One Line From Below And Paste It Below The
Third Line.
//Just Replace the first word in quotes with the word you would like,
//and the second word in quotes to what you would like to change it to.//

$message = str_replace("bad word1","**",$message); /* Replaces the word
"hey" into "****" */
$message = str_replace("bad word2","**",$message);
$message = str_replace("bad word 3","**",$message);

echo $message;

}

return check(); //* Returns the function check() */

?>

I would like to keep this as a separate file and include it into the main
file. In the main file I inserted the two code lines:

include('badwords.php')
check('$message')

I've tried a lot of different things to get this to work but I always get
error messages when I run it on my website. I would like to keep it in a
separate file from the main file because of all the bad words. Also I need a
function because I would like to have it check the variables for several
fields.

So what should I do to get this to work?

If you're calling it as

check($message)

you need to change the declaration of the function to

function check ($message)
{
....
}

and remove the "return check()" line from the separate page where you
have the function. Also, it would help if you told us exactly what
errors you are getting.

Greetings.

I've made the suggested changes and the error I get is:

Parse error: parse error, unexpected T_STRING in
/home/songc1/public_html/guestmap/guestmap_place.php on line 27

In the file guestmap_place.php, I have the lines:

include('badwords.php')

check($message)

Line 27 is ' check($message) '

The file ' badwords.php ' now reads:

<?php
//* badwords.php */

function check($message) /* Establishes the function check */
{

global $message; /* Gets All Variables */

//To Add New Words, Just Copy One Line From Below And Paste It Below The
Third Line.
//Just Replace the first word in quotes with the word you would like,
//and the second word in quotes to what you would like to change it to.//

$message = str_replace("badword1","**",$message); /* Replaces the word "hey"
into "****" */
$message = str_replace("badword2","**",$message);
$message = str_replace("badword3","**",$message);

echo $message;

}
?>

I believe I've discovered two problems with the code. First I didn't put in
the ";". So I changed the file in guestmap_place.php to now read:

include('badwords.php');
check($message);

Also I realized that I had a problem with the file name "badwords.php". The
actual file had a space between the "s" and the ".". I corrected that.

Now I get this error message:

Warning: Cannot modify header information - headers already sent by (output
started at /home/songc1/public_html/guestmap/badwords.php:38) in
/home/songc1/public_html/guestmap/guestmap_place.php on line 75

Interesting the bad word filter seems to be working, but now the program
will not refresh the screen. I get this message:

Warning: Cannot modify header information - headers already sent by (output
started at /home/songc1/public_html/guestmap/badwords.php:36) in
/home/songc1/public_html/guestmap/guestmap_place.php on line 75

I believe line 75 must refer to this line of code:

//go back to the map
header('Location: '.$_SERVER['HTTP_REFERER']);

I'm not sure what to do.

I'm not sure what to do.

The line
header('Location: '.$_SERVER['HTTP_REFERER']);
is trying to set the header information AFTER
/home/songc1/public_html/guestmap/badwords.php:36
has already set the header information, by:
(a) issuing a print or echo statement
or
(b) containing some white space that the browser is rendering as output

The more common problem is (b)

Best way to check is to call badwords.php directly into a browser, and see
if you get any (even blank) output rather than a "document contains no
data" message.

Thanks for eveyone's help. It seems to be working now. Here's the program I
came up with:

start of program

<?php

//* badwords.php */

//* Establishes the function check */
function check($message)
{

global $message; //* Gets All Variables */

//To Add New Words, Just Copy One Line From Below And Paste It Below The
Third Line.
//Just Replace the first word in quotes with the word you would like,
//and the second word in quotes to what you would like to change it to.//

$message = str_ireplace("badwordq","**",$message); //* Replaces the word
"hey" into "****" */
$message = str_ireplace("badword2","**",$message);
$message = str_ireplace("badword3","**",$message);
}

?>

end of program

The header problem seems to have been caused by a single space after the
"?>" at the very end.

Also I replace str_replace() with str_ireplace because str_ireplace is not
case sensitive.

In the main program I inserted the lines:

include('badwords.php');
check($message);
