CGI Q's

[KieranSmith]

Hi,

A few Q's relating to some cgi problems which i would be grateful if u could solve:

- How do i loop through a file and if the string is not in the flat file then to append the string to the end of the file?
- How do i parse entered text and remove all extra lines and replace them with spaces?


Thanks

sorry I don't have a clue on the first one, but the second one can go something like this

# make conversion of the newline character to breaks and paragraphs.

$as{'field_name'} =~ s/\n/-break-/g;
$as{'field_name'} =~ s/-break--break-/<p>/g;
$as{'field_name'} =~ s/-break-/<br>/g;
$as{'field_name'} =~ s/ +/ /g;

then you would write it to the file. is that what you're after?
