 |
|
Hi i am attepting to remove '+' signs from a form posted via a cgi script to another one.
To do this i propose to use:
$subst = /\+\+s/;
to identify and replace '+' with a whitespace character. Will this work, and how to i pass the posted outut through this comparitor?
Any help appreciated,
Cheers,
marc

A perl regex to replace '+' characters with spaces is | Code: | | $string_with_plusses =~ s/+/ /; |
| Quote: | | and how to i pass the posted outut through this comparitor |

i want to get the values passed from the first script, in the second, then run the comparison to remove '+' signs and display it on the webspage.
Cheers,

Try:
| Code: | | $string =~ s/\+//g; |
If you don't despecialise the plus sign it will not parse. You need the g to catch lines with multiple plus signs otherwise the regexp will just strip the first one.
If I understand your last question correctly on passing the value to another script, just pass it as a parameter to the second script and recover it from @ARGV.
