I'll have to study your regexp - a lot of stuff I don't understand yet in 
play there.  Thanks for the sample!

OK - I don't yet understand how this works, but it seems to work for almost 
all cases.  The one erroneous result I get is from a value of 0040 (which I 
convert to 00:40 before hitting the regexp).  It comes thru as Ok.  If you 
have a fix for that I'd appreciate it - otherwise I'll have to devote some 
book-time to mastering this string and come up with a fix myself.

Thanks again!!

Based on your requirements, 00:40 is completely valid. Why do you think it 
should be invalid?

00:40 is not a valid 12-hour format.

BTW I just found another non-regex approach. Its even faster.

function valid_time_Shiplu2($time) {
sscanf($time, "%2d%2d", $h, $m);
return ($h>0 && $h<13 && $m>=0 && $m<60);
}

Don't know how you write the time, but I've never used a time of 00:40. 
Yes, I realize that my shorthand time string is missing a key ingredient of 
am/pm, but 12:40 would be the time in my mind regardless of the status of 
the sun.  In my speccific use of this code, all times would be 'daylight' 
times so 40 minutes after minute would be a) not practical and b) still not 
a recognized time in a 12-hour format.  Yes - in 24-hour formats, 00:40 is 
correct, but my initial post did reference my need of a 12-hour format 
solution.

Sounds daft to me, but they're your requirements. The "fix" is simple…

( 0 <= (int) $m[1] && 12 >= (int) $m[1] ) &&

becomes

( 1 <= (int) $m[1] && 12 >= (int) $m[1] ) &&

Daft is a little harsh.  :)  00:40 is just not a time value that is 
generally accepted.

As for you patch thought - THAT is generally accepted.  Works great now. 
Thank you.

Now all I have to do is read up on this stuff so I can understand how it 
works.  But first - golf!

It may appear harsh, but as far as I'm concerned it is daft to make assumptions 
like that. You've essentially disallowed 12:nn am, but allowed 1:nn am, 2:nn 
am, 3:nn am, etc, because you're not validating the data in a non-ambiguous 
way. I have no idea what you're developing, but you're making a big assumption 
about the data that you're getting, which may appear reasonable to you, but to 
me it's daft. Nothing personal, just my opinion, which is all I have to offer.

[PHP] Bust out a PDF via the print stylesheet?

2012-05-18 Thread Brian Dunning
Hey all -

The articles on my web site already have a very nice stylesheet that produces a 
print version. Does anyone know if there's a such a thing as a PHP class that 
would let me put up a "Download PDF" link that would generate a PDF doc on the 
fly, using that same stylesheet? I've used various PHP PDF classes before, but 
I'd rather see if I can shortcut this rather than assembling the doc from 
scratch.

The third part of your alternate expressions matches "3:00" from the 
string "13:00" (it ignores the 1 at the beginning). Using ^ avoids this 
because now only one digit is allowed before the :.

Ok - here's the use.  This feature is the scheduling portion of my 
application.  The scheduling only pertains to basically daytime hours, 
typically 8:00am to  6:00pm.  The information is used for display purposes 
mostly - there is no "calculating" going on with the data.  Consequently, 
there is no need to be all-inclusive on my allowed times since they will 
never be used.  I just want to validate the entries  to be sure that a valid 
time has been entered for that period of a day.  Noone is going to schedule 
anything for a midnight hour, not even a time after 8:00pm.  Therefore I can 
be very specific about my editing criteria and can limit the entry of data 
that fits within that schedule.

If the ":" separator is inserted before the regex check, the following
should suffice:

'/^(0?[1-9]|1[12]):([0-5][0-9])$/'
