Validation of Field... Seeking Alternitive Method

[Anon]

Hello.

I am using the following method to ensure uses don't use specific "words" within a field.... I was wondering what a better method would be... something that would allow me to add more "words", without all the: $name == ""; methods!

if ($name == "test" || $name == "Test") {
echo "<center><b>$lang_invalid_name!</b><p><br><p></center>";
exit;
}

Any suggestions?

Thanks!

Ok, here is the other method I use... I guess I should have asked if there is a better method then this one...

Within my php file:

if ($CensorList == "On") {
require "CensorList.inc.php";
while (list(,$var) = each($words)) {
echo "<center><b> Invalid Name </b><p><br><p></center>";
exit;
}
}

Then I have another file called "CensorList.inc.php" with the following:

$words[] = "test";
$words[] = "Test";
etc. etc.

Is that a good method, or anybody know anything better?

maybe

$badwords = array("@!#$", "piss", "test");

for ($i=0;$i<count($badwords);$i++) {
if (eregi("$badwords[$i]", $name)) {

print "Bad word found in name field";
}
}

Then you could add as many words to the $badwords array as you like

Thanks Louie!!

just incase of someone comes along and decides to use it... make sure you comment out the @ mark... or remove the "@!#$", part....

Again, Louie, Thank you!

Good call, I actually had a badword in there but it looks like they censor that type of thing on this forum

Make a plaintext file, on bad word on each line.

In your code, when you look for anughty words:

$bad_words_array=file("your_textfile_here");

then fetch a word to compare to the badword list, and then

if (in_array($word,$bad_words_array))
{
print "naughty word used\n";
};

in_array() is a php4-only function, but trivial to write in php3 code.

I want to make sure that user enter date in for e.g. 12/11/00, this format.
