Comments:
<0> zn--: You're making a CGI script
<1> unless(defined($var) and $var ne '') ...
<2> or $foo2=bla$foo=
<3> zn--: CGI.pm will present those as empty strings.
<0> zn--: And the variable wasn't given or empty?
<4> if param('foo1') is not defined
<5> my $value = param('key'); defined $value or $value = ''; if ($value eq '') {...
<2> pravus yes that is what I'm looking for
<3> You might as well do 'if'
<2> dazjorz webspam bots are sending my form, and some send nothing
<2> some send the right params, some send some null, some forget them
<3> Since there's nothign useful that will be false
<2> just adding some restrictions so the 200 bot requests a day don't fill up an inbox
<4> what does "null"mean? an empty string?
<0> zn--: buu said that CGI will give them as empty strings, thus ""
<6> \0 ?
<0> zn--: So: if($cgi->param('this') eq "") { it's empty } else { it's filled }
<2> so I can just do $foo != "" ?
<5> zn--: you can't use != on strings
<0> zn--: != is for numbers
<1> dazjorz: need to check definedness as well
<0> zn--: You want ne
<7> sure you can
<6> use ne instead of !=
<7> it just won't do what you want most of the time
<2> c# it works hehehehe ok thanks
<0> pravus: [04:29] <3> zn--: CGI.pm will present those as empty strings.
<5> stop writing CGI programs in languages you don't know
<0> pravus: I thought that too
<0> pravus, but you guys are probably right
<2> mauke I'm not, just editing a line or two of something I didn't write
<1> dazjorz: no.. CGI.pm doesn't define params that don't exist
<1> ?foo=bar ->params('baz'); returns undef
<0> pravus: I knew it!
<0> pravus: just thought buu probably knows more about this
<0> pravus: I always use defined() too
<1> dazjorz: i think buu was talking about: ?foo=
<0> pravus: Yea, me too
<1> ->param('foo') is defined, but ''
<3> Well, yeah, if you define a form with three fields, the browser will try to send them all
<2> for me the issue isn't browsers, mine are spam bots
<1> zn--: no, your problem is *clients*
<3> Ya know, if I had a mother like that I'd never be back..
<8> can someone have a look at my code http://sial.org/pbot/18107 I am a little stuck for some strange reason everything after my 9$content3) is not being executed, and the loop just continues befoe that
<1> clients cannot be trusted
<1> be they browser or bot
<2> pravus correct
<9> http://sial.org/pbot/18106 <-- anybody, anybody?
<3> What about it
<3> samasama: Well it's silly and entirely too long
<10> I have only have one more question, how could I work with a string, say I knew that "2005" would be in $var at all times...how could I remove just that? I've tried..everything! (well obviously not :P)
<7> frelen678: why are you using a for loop for a single value?
<4> samasama - why not use IO::Socket, and reduce that to two lines?
<5> Yawgmoth7: you want to remove all occurrences of "2005" in a variable?
<7> $foo =~ s/2005//;
<3> Yawgmoth7: use s///
<10> *sigh*
<10> I guess I'll end up setting up more than one regex
<7> of course this sounds like a XY problem
<9> merlyn: I've been asked by a higher authority to write it like that
<3> samasama: Kill them.
<9> heh
<4> is this for homework?
<10> Oh well, I'll jsut do it like that.
<1> Yawgmoth7: $var =~ s/2005//; ?
<4> if it's homework, DON'T ASK US
<4> ask your teacher
<9> nah, not homework
<4> asking us is CHEATING
<1> cripes i think freenode is lagged
<2> I got it working, thanks guys I didn't write this app just tweaking it
<4> then what kind of higher authority are you speaking of?
<4> besides, we're the highest perl authorities around here. :)
<3> merlyn: Cheating rocks!
<4> and we say use IO::Socket, or abandon any idea of help
<9> merlyn: Boss
<5> yeah, we're totally high
<6> especially merlyn
<4> get a new boss
<6> o/` meet the new boss // same as the old boss o/`
<4> have your boss call me, and I'll personally explain to him why you should use IO::Socket
<8> Khisanth it worked as it was before, what would u suggest instead?
<1> merlyn: and charge a fee, of course...
<7> and then there is the catching of exceptions that aren't being thrown ...
<3> pravus: I think he drunkely yells down phones for free
<9> merlyn: What's so wrong with crafting it by hand?
<4> how do you catch unthrown exceptions
<3> samasama: It's wasteful, slow, pointless, useless, prone to mistakes, etc
<4> samasama - at that rate, your question could extend to "why not code it in ***embler"?
<9> merlyn: Good question
<6> ***embler is for wimps. machine code!
<9> samasama: Is it actually slower?
<9> buu even
<3> Sure
<7> merlyn: I forgot "trying"
<7> samasama: if there wasn't anything wrong, you wouldn't need to be asking for help!
<7> samasama: to write yes, in execution probably not
<9> Khisanth: hmm?
<4> & zzz
<6> g'night, merlyn
<11> I know the answer to this but cant find it on google.. I want to check the value of a scalar, and if it has no value at all {stuff}
<11> but $scalar == "" or $scalar eq "" is wrong
<4> what does "no value at all" mean?
<3> b0nn: What?
<8> Khisanth the foreach loop was the only way the program would run
<4> geez - why do we keep getting these questions lately?
<6> as in "is it defined?"
<12> if($scalar) { ... } ?
<4> do you mean "zero length string"?
<3> b0nn: Do you want defiend?
<11> ta chrisbdaemon
<4> or defined?
<4> or what?
<11> I mean has no value whatsoever
<12> does ta mean yes or no
<4> it can't have NO value
<7> frelen678: if you insist
<11> ta means thats what I think it should be
<4> it's either undef, or an empty string, or a non-empty string
<12> do you mean undefined?
<4> purl, xy problem
<3> merlyn: Well, undef is a no value anyway =]
<4> oops.
<4> perlbot, xy problem
<13> They ask how to do X, but that's because they really want to do Y but think X will get them there and most of the time they are WRONG
<4> b0nn - back up
<8> but I am wondering what would casue it to go into a loop and ignore everything after $content3
<4> what are you TRYING to figure out
<4> what's the problem that this is a partial solution to?
<11> Im trying to figure out if a value has been p***ed to my scalar
<7> and it's $! not !$
<4> back up - how could it NOT be p***ed?
<4> what are the choices? how is this being called?
<11> if theres nothing held at that point in my array to p***
<4> what do you mean "in my array"?
<11> what do you mean "what do you mean \"in my array"
<4> dude - pull attitude, and you get no help. I'm trying to help you
<3> IT'S RECURSIVELY GONE PEARSHAPED
<4> but I have to figure out what the hell you're trying to do
<11> why?
<7> although !$; is valid, it is extremely unlikely that you want the logical negation of the subscript seperator
<4> because your question doesn't yet make sense
<3> b0nn: Just use 'defined' and move on.
<4> so I need to move up a level.
<14> Khisanth, I want that all the time!
<11> it is defined though
<4> if it's defined, then it's a value
<7> beth_: you don't count
<14> :(
