Kevin,
There are two things you want here:
1. Attribute values should be quoted. For example:
<a href="images/some.jpg">
2. You want to use HTML::Entities to encode the data.
#print "<a href=\file-scipt.cgi?name=$word&option=$display\>$word</a>";
use HTML::Entities;
# later
$word = encode_entities( $word );
$display = encode_entities( $display );
print qq|<a href="file-scipt.cgi?name=$word&option=$display">$word</a>|;
Note the use of & to separate name/value pairs in a query string when the query
string is in
HTML.
Incidentally, here's a neat trick taking advantage of the fact that $_ aliases the
variable in
question when using for loops:
for ( $word, $display ) {
$_ = encode_entities( $_ );
}
If you have many variables to encode, this will do it fairly conveniently.
