baklava

yea

jeev

mind helping my sexy ass

baklava

what's up?

http://www.pastebin.ca/1590821

jeev

im sending $1 through $4 through a php with POST to another php
the other php which im posting to is taking $1 through $4
it works OK but the problem is that i want to accept more than one check
get what im saying

[09:34]

baklava

somewhat, can I see it?

[09:35]

BeBoo_

array, jeev ?
you can serialize an array and send it to the second php script

[09:35]

jeev

[09:36]

BeBoo_

so the second script just decrypts the array

[09:36]

jeev

i read the array's for checkbox
making them the same name and adding a [] but i couldn't read it
alll i could do is dump it
i still dont understand how i could make it add the selected product names and descriptions and price together

[09:36]

BeBoo_

you want to add the total or what was selected?

jeev

add the total + name and description

baklava

this looks like a job for OOPHP

BeBoo_

i would do a multi-dem array
using []

jeev

yea tried that last night

baklava

you should have an array of check
s
check objects

BeBoo_

$products['name'][]
$products['desc'][]
$products['price'][]
something like that

baklava

that have all this stuff, so you don't have to fool around with it

jeev

the name and description are actually set inside the php that's posted TO

BeBoo_

ah ok

jeev

the set up is if $1 is enabled, set this..
http://www.pastebin.ca/1590821

BeBoo_

would still be the same

[09:39]

jeev

im a pretty big noob, just starting to learn the basics of coding.

[09:39]

BeBoo_

i can help you with it, it's not too hard
i did something similar when i created my dns panel

[09:40]

jeev

ok
do you want me to set up the array again

[09:40]

BeBoo_

did $dns['A'][]
etc

[09:40]

jeev

ok, i did:
<input type="checkbox"
name="option[]" value="0" />
through option 4
is that right
then it gets posted to the php that i showed you

BeBoo_

to be posted to the script you pastebined? no

jeev

how come
no
i put that in the previous file
which posts to what i pastebined

BeBoo_

you just need to call that something. you handle that in the resulting script

jeev

this is right
i set it in the right script

BeBoo_

can you maybe send me the entire two scripts so i can understand what you are trying to do?
i'm still a little lost at what this does

jeev

well give me a second first
let me explain this

BeBoo_

jeev

right now
it's spitting out the array
whatever i check.
cause i tried it last night
the php i pastebinned is what is spitting it out, the entire thing
it's some nasty code, i really can't sift through it

[09:43]

BeBoo_

lol

jeev

Array ( [0] => 1 [1] => 2 )
if i check box 2 and 3
that's what shows up, whcih is right
i named them 0,1,2,3,4

BeBoo_

jeev

what do i now? how can i accept this
$_POST['option'][]
?

BeBoo_

is that the array?

jeev

yes

BeBoo_

see the name is wrong... on the input type
i feel
you can't have a postvar with that name

jeev

BeBoo_

it would be $_POST[
err

jeev

that's what im telling you, is i was stuck here

BeBoo_

$_POST['option[]'][0]
oops.. replace the } with ]

jeev

oh, why then is the [] necessary

BeBoo_

it isn't
-_-
thats why i said the name is wrong

jeev

i read that that's how you start an array

BeBoo_

in PHP, yes
but not in html
that is just a name of that field
that has nothing to do with starting an array

jeev

so the []'s are useless?

BeBoo_

yes

jeev

sec

BeBoo_

in those <input> tags

jeev

so just name
option.
that's it ?

BeBoo_

yes

jeev

and a value
done

BeBoo_

then, in the resulting script, use $_POST['option'][0]
or
$_POST['option'][1]

jeev

BeBoo_

might need to put those in single quotes tho
$_POST['option']['1]
gah

jeev

but where should i put it

BeBoo_

i am still waking up, sorry

jeev

what should i surround it with
should i like $0 = $_POST['option']['0']
?

[09:48]

BeBoo_

where ever you are testing the first checkbox which i'm guessing is $porduct1 ?

[09:48]

jeev

[09:48]

BeBoo_

$product_1 = $_POST['option']['1']
oooo wait a sec

Thorgrimr

You just trying to allow them to submit one from a list?

jeev

yea

BeBoo_

i am totally confused

jeev

Thorgrimr

If they can only choose one, use radio buttons

BeBoo_

if you only want one, you need to use a radio button
not a checkbox

jeev

no
not submit one from a list

BeBoo_

and you would do a case statement on $_POST['option']

jeev

sorry i read that wrong
i have 5 checkboxes
any 5 combination could be selected
actually, i have one select all which sends all.
the other combination of 4 could be selected
i want it to add it together.

BeBoo_

jeev

it's a service with options.

BeBoo_

forget what i said earlier. -_- those checkboxes need different names
like prod1, prod2, prod3

jeev

sono array ?

Thorgrimr

Then use your <input type="checkbox" name="product[]" value="1" /> etc

BeBoo_

jeev

hmm
that's what i read last night

Thorgrimr

THen you have an array named product, that you can iterate over

jeev

yea

BeBoo_

but it would be within $_POST[]

jeev

i get that it sends over the array
yea BeBoo_

Thorgrimr

Yes

jeev

but i dont know what to do after that
i mean i can get it with _POST

Thorgrimr

if ($_POST['product'][1]) { box 1 was checked) etc

jeev

but do i have to have that for each product and possible product
to match it up?
if product 1 and 3 are selected..

[09:53]

***

ballen|away is now known as ballen

[09:53]

Thorgrimr

Just run it through a while or foreach loop

[09:54]

jeev

hmm

[09:55]

Thorgrimr

foreach ($_POST['product'] as $index) { $price = $items[$index]['price'] } or some such

[09:56]

jeev

jeev is lost

[09:57]

BeBoo_

lol

[09:57]

Thorgrimr

Sorry ;)

[09:58]

BeBoo_

sec, jeev, working on it

jeev

i sort of understand the foreach
but i'm just lost

BeBoo_

lost where?

jeev

how do you set the prices of ecah product
then the descriptions and add them together

Thorgrimr

Set up an array of hashes and store that info in it
Then you can just reference those values by the boxes the user checked
Iterate over their choices picking out the checked products and sum em up

[10:01]

jeev

hm
why do i even need an array, the previous way iw as doing it
it was just sending which ever name was enabled, the value
i mean it was just fine

[10:03]

Thorgrimr

You don't

jeev

i just needed a way to add up the fields

Thorgrimr

But if the number of products increases, your code to process it will have to keep increasing

jeev

yea it really wont
it's not a shopping cart for items, just a service with options
a couple options

Thorgrimr

By iterating over an array, the code never changes regardless of whether you offer 5 or 1000 options

BeBoo_

jeev: then then do $sum = 0; then in the if statements just to $sum .= $price;

jeev

i understand

BeBoo_

err not .=
lol

Thorgrimr

BeBoo_

yeah that
sorry

jeev

bah

http://www.pastebin.ca/1590873

BeBoo_

i need some tea or coffee or something

[10:06]

jeev

i need a miracle
http://www.pastebin.ca/1590821
can i set
product_1's product_name to product_name1
and ... for the rest
then try to add them up
$product_name1 + $product_name2 + ..

[10:06]

BeBoo_

[10:07]

jeev

[10:08]

BeBoo_

depends on how you want to output it

[10:08]

jeev

and the same with text, right

BeBoo_

that code will just add the prices

jeev

except, how would i put ,'s
to separate

BeBoo_

$products .= ", ".$product_name
in each if
cept the first one
drop the comma
lol

Thorgrimr

But then how does he know which is the first value they actually checked
I would do something like
$product_desc[] = 'THe Description'; in each if

[10:10]

jeev

nice, it adds it

Thorgrimr

And then just do a $prod_descriptions = implode(',', $product_desc);

jeev

i wish i could code man

BeBoo_

http://pastebin.ca/1590877
right
true
scratch taht post
thats a good trick, Thorgrimr

jeev

rfmfhrmrhrmfm

well
Thorgrimr helped me
im almost done, just have to work out some minor things with his code and i'll be done ;)

[14:59]

BeBoo_, ther e?

[15:11]

BeBoo_

yup

[15:11]

jeev

Thorgrimr helped me out but he's not here
i have a question
$price += $values['price'];
that's set up under _POST['all']
i want to reduce it by 10% if all is checked
which lets just say is 55 right now
how can i subtract it at the end

[15:11]

BeBoo_

$price = ($price * .9);

[15:12]

jeev

$price += $values['price'] - 55;
subtracts that
55 from every thing

[15:12]

BeBoo_

need to seperate it out

jeev

heh

BeBoo_

you are telling it to add $values['price']-55 to $price
so just $price += $values['price']; $price -= 55;

jeev

ahh

BeBoo_

or use the * .9 which will give you 90%
gotta think backwards sometimes
it's weird

jeev

wait, borked

[15:15]

***

bithash has quit IRC (pratchett.freenode.net irc.freenode.net)

[15:16]

jeev

coming up with a weird price

[15:16]

***

bithash has joined #arpnetworks

[15:16]

jeev

yea .9 works too
the $price -= 55; doesn't work
does 55 from everything
$pricetotal += $values['price'];
$price = $pricetotal - 55;
worked
well
the thing he did for me was good, i kind of learned from it
i just need to now have the output of the page read the code
cause it doesn't output the way i need it to
if ($count > 0 || $count == 'all')
what does that mean /
if there is more than 0 selected?

[15:17]

BeBoo_

$count > 0
means more than 0 are selected
|| mean or
soo
_if_ there are more than 0 items selected or $count == 'all'

[15:25]

jeev

ok
figured
he has it printing under that to the screen, what's selected and how much
but i need it to go to the bottom part of the page
maybe i'll try to figure it out myself

[15:26]

BeBoo_

bottom part?
oh he's probably using var_dump
?
theres another one... i can't remember the name

[15:34]

jeev

na
yea, got it
yay

[15:40]

BeBoo_

nice

[15:44]

jeev

HELL YES!
just one problem
since there are so many products and descriptions when multiple are selected
it changes the format
but it's ok i think

[15:48]

***

heavysixer has joined #arpnetworks

[15:57]

jeev

problemski
i need to make one option required.

[16:01]

echo " <b><p>" . implode(', ', $descriptions) . "</b>n";

wee, got it

up_the_irons: in the colo biz, whats more expensive power or rack space. In other words, would a high end power hungry server that takes 1U be better, or 4 1U servers that take hardly any power

[16:42]

jeev

power i think
depends where you are
you gotta remember, you're probably paying extra for UPS
some people want 20 bux an amp
but if you get a good deal, you may get the rackspace for like 10 bux per U and 10 bux an AMP

[16:43]

ballen

yea
ideally multiple boxes would be better
as they're cheaper to buy, cheaper to replace, and offer more redudancy
such as one of these bad boys: http://apcmag.com/dell-uses-via-nano-netbook-chip-to-create-modular-mini-servers.htm

[16:44]

jeev

damn
how mush

[16:48]

ballen

checking...
the power stats on that box are amazing
25watts fully loaded

[16:48]

jeev

jeebus

[16:49]

ballen

thats 12 units
perfect for scalling horizontally
give each node a 32G SSD
as much memory as it support
and you officially have one hell of a distributed hash db

[16:49]

jeev

how mush monies

***

heavysixer has quit IRC ()

BeBoo_

not a fan of SSD

ballen

still looking
BeBoo_ they're lower power yes?

BeBoo_

of course at the cost of speed
tbh, i'd rather a few 15,000 RPM drives myself

ballen

whaaa. they are wicked fast

jeev

BeBoo_
can i
$products2[] = $items[$key]['name'];

BeBoo_

ballen: might want ot research that a bit

jeev

$products[] = $products2[] + fart;
or something ?

BeBoo_

ssd speed is equiv to like a 4200 rpm drive
jeev: what is "fart" ?

jeev

a product
since
#
$items = array( '1' => array( 'price' => 100, 'name' => 'Product 1', 'desc' => 'Product 1'),
#
'2' => array( 'price' => 0, 'name' => 'Product 2', 'desc' => 'Product 2'),

[16:53]

BeBoo_

period combines if that is what you are looking for
you just want to add to the product array?

[16:53]

jeev

says cannot use [] for reading
yea
i have a required product

[16:53]

BeBoo_

no you can't

[16:54]

jeev

which i want to add
i want it tobe added in everything but ALL
which i can do

[16:54]

BeBoo_

jeev: try $products = array_merge($products, $products2);

[16:54]

jeev

BeBoo_

is products2 an array?

jeev

$products[] = array_merge($productrequired, $products2[]);
can i do that
yea

BeBoo_

you can't use [] to read
-_-
it knows that $products2 is an array if you are using that dunction
function
it returns an array

jeev

ah
what should i dooo
;/

[16:56]

BeBoo_

http://www.php.net/array_merge
what i said before...
$products = array_merge($productrequired, $products2);
?
don't use {}
[]*
it combines

[16:56]

jeev

ahh

[16:56]

ballen

jeev: that dell server isn't generally available

jeev

ah
BeBoo_
what if $productrequired isn't an array
$productrequired = fart;
$products[] = array_merge($productrequired, $products2);

ballen

appears to be only for dell's customers that have some special relation

jeev

no error is produced
but it doesn't add the text fart
$products2 = an aray
$products2[]
i have to turn productsrequired into an array i guess

BeBoo_

yes
you can't slap just a string into an array
well, you can
if you wanted to
but it won't match up and will likely break your script

[16:58]

ballen

BeBoo_: http://it.anandtech.com/IT/showdoc.aspx?i=3532&p=13
"ntel X25-E is nothing short of amazing: it offers at least 3 to 13 times better OLTP performance at less than a tenth of the power consumption of the classical SAS drives. "

[16:59]

BeBoo_

thats news to be because i just did a bit of research on that about a week ago

[17:00]

jeev

damn

[17:00]

ballen

SSD drives have always been faster

[17:01]

jeev

i got an ssd in my laptop

[17:01]

ballen

especially the Intel's
really the ideal setup would be two SSDs and a set of slower SATA drives in ZFS
ZFS is smart enough to do writes to the SSDs and move it around later

basically big cache drives

[17:01]

BeBoo_

i haven't played with zfs yet

[17:02]

ballen

its an amazing piece of software
and if by chance you have an application that does a lot of sequential reads/writes SSD owns all

[17:02]

jeev

BeBoo_, no go with arraymerge

[17:06]

ballen

also since there is not moving parts, reliability goes up a bit

[17:06]

jeev

BeBoo_, the thing im tryign to add is in the array as '1'
its just disabled in the post script
cant i just
yea man i should be able to emulate it's checked

[17:06]

BeBoo_

ohh
you want to add 1 to which array?

[17:07]

jeev

hold up

[17:08]

BeBoo_

i'm still kinda lost on how this script is working
hard to help without seeing it
lol

[17:09]

plus it would look like it was yours and not hosted somewhere else

[23:37]

up_the_irons

I use that support app b/c it was geared toward support, and has stuff like search, ticketing, etc... all built in. but i'm wondering if I should just make my own, simpler, KB on my own site w/ Sinatra, and just make it searchable

dbgi

up_the_irons could u delegate rdns to my ip 206.125.172.78?
if that makes any sence

up_the_irons

ballen: yeah i hear ya on that... there's some way to change the CSS on that though

dbgi

sense

up_the_irons

dbgi: your whole /28 ?
ballen: i you know of any Sinatra plugin that makes pages "searchable" (for lack of a better word)

ballen

up_the_irons: maybe try to fix the CSS, is that a hosted solution or a app you're running?
uhh
searching...
is just a pain in the balls
in general

[23:39]

dbgi

up_the_irons yea if thats ok

up_the_irons

ballen: it's hosted, but there's a way to upload your own CSS, or something
dbgi: sure, what rdns software are you running?
ballen: I will make note of it, "pain in the balls"

there is Ferret, http://www.davebalmain.com/

dbgi

coool thanks

ballen

with is a ruby search index
which*
which just halls ass in perf

up_the_irons

yeah i've used ferret
i've used sphinx more

[23:42]

ballen

which one is better

[23:42]

up_the_irons

sphinx
thinking sphinx is quite a nice lib: http://freelancing-god.github.com/ts/en/
but i'm purposely avoiding any ActiveRecord within my site (the Sinatra portion, at least)
this is very integrated: http://www.rootbsd.net/faq/
i want my faq to be like that...
not a bunch of different "articles" you have to search for or find in a directory

[23:43]

ballen

there ya go, one big ass page

[23:45]

up_the_irons

plus if i host my own faq, i can see statistics on it, i can even host mini howto's

[23:45]

ballen

let the user search
with their browser

[23:45]

up_the_irons

up_the_irons sense sarcasm

ballen

wicked simple app
nah

up_the_irons

*senses

ballen

seriously
by far the most simple solution
why do anything more difficult

up_the_irons

i mean, personally, i hate f*cking click around everywhere to find what i need; i'd rather have it all in one page and hit "/<term>[enter]" (i use vimperator)

[23:47]

ballen

wasting time on it when you could be working on something else

[23:47]

up_the_irons

ah roger
that is what I'll do then
i kinda like how Sinatra documentation is like that

[23:47]

ballen

yea

up_the_irons

it's like one page of "Getting started", and then "The Manual"
and that's it
top to bottom

jeev

ballen

ballen

yea the people behind Sinatra get this whole perfectly minimalist thing pretty well

jeev

that scanty thing looks like a headache

ballen

heh
jeev: easy as hell

up_the_irons

scanty?

jeev

i like the sysadminchronicles

ballen

checkout tumblr.com if you want a hosted solution

jeev

ballen

ballen

can customize it fully

jeev

i have a million servers
whywould i want to host it elsewhere? :D

ballen

its free
and wicked easy

jeev

i'll download it, i duno
which database should i use though

ballen

up_the_irons: http://github.com/adamwiggins/scanty-redis
Sinatra app

jeev

i've never heard of redis

ballen

its a Key/value db
that rawks
up_the_irons: its running my blog sysadminschronicles.com
not that exact version, but thats what its derived from

jeev

up_the_irons

ballen: (reading some scrollback) -- about the colo, hard to say; i think a high end 1U would be cheaper than 4 low end 1U's. "hardly any" power for a 1U would be like 0.5A, at the very minimum, which is still something; a high end 1U would be like 2A

[23:54]

ballen

even if the low end 1U was running an Atom CPU drawing like 25 watts
max
also how about squeezing 2-4 servers into 1U

[23:54]

up_the_irons

ballen: the Atom may draw only 25 watts, but the main power supply to the box will be a lot more
here's an interesting stat:

[23:57]

ballen

nah the whole box draws 25 watts

up_the_irons

my one big VM server was using 2 amps before I put in that second Intel Xeon E5430 2.66 GHz Quad-Core bad boy
guess how much it drew after I added the second CPU?

ballen

up_the_irons

nope
