Need help on this error

[Anon]

Hey all, I get this warning...."Warning: Delimiter must not be alphanumeric or backslash" And here is the code it comes from, but I'mnot sure what the problem is.

while ($row = mysql_fetch_array($myresult)) {

	$theword = $row["word"];
	$worddef = $row["definition"];

	$caption = "Definition: ".$theword."";
	$replace = "<a href='javascript:void()' onMouseOver='overlib(\"".$worddef."\", CAPTION,\"".$caption."\")' onMouseOut='nd()'>".$theword."</a>";

//THIS IS WHERE THE ERROR IS $forminput = preg_replace($theword, $replace, $forminput);

}

Try changing your $theword to be:
$theword = "/" . $row["word"] . "/";

Perl regular expressions need to have a starting and ending delimiter you need to choose some character that doesn't exist in your pattern to suround your pattern with.

What if I don't want anything on it. I try to make it spaces and it didn't work??

I'm sorry I don't understand your question.

Perl regular expressions have this syntax.

(delimiter)pattern(delimiter)

The delimiters are not optional, and are not part of the pattern, they just give the regular expresion parser a way to know where to start and where to end. The delimiters can be any non-alphanumeric character (i.e. !@#$%^&*|/). Forward slash is the typical choice, but you don't have to use that one.
