<0> what is the difference between ( !$_FILES['userfile']['tmp_name'] ) and ( $_FILES['userfile']['tmp_name'] != NULL ) ??
<1> Etobicoke27m: they're the exact opposite?
<2> netbeans is slow as ****
<0> evulish: are you asking me?
<0> I'm asking you :)
<1> i'm saying that's the difference
<1> but it seems rather obvious
<0> well... I thought ! preceeding a variable meant "if the variable does not exist, or is null"
<1> != = not
<0> ****... heh... I just realized what I did
<0> what I MEANT was.... is $_FILES['userfile']['tmp_name'] is the same as $_FILES['userfile']['tmp_name'] != NULL
<0> ?
<0> can I just do a if ( $_FILES['userfile']['tmp_name'] ) {
<0> I know it sounds like a dumb/easy question... but just wanted to make sure I dont have to explicity say != NULL
<1> you should really just use isset()
<1> otherwise you'll just generate a whole bunch of notices
<3> google march 20th for the best holiday ever
<0> evulish: ok... thanks
<1> **** NOTHING WILL DO WHAT I WANT
<4> stop using java?
<4> python ftw
<1> i can't
<1> i'd use anything over java
<1> it's so ****ing convoluted
<1> how do you get **** done
<4> jython?
<1> you dig and dig and dig and dig to find something to use
<4> yeah
<4> that's Java for you
<1> i still haven't found a way to do what i want
<1> it's been like 4 hours
<1> i've written code that almost sorta worked
<4> lol
<4> I find it funny that ****ing insanely complex **** is easy in Java
<4> but
<4> Insanely easy **** is ****ing impossible
<1> haha.
<1> import java.util.QuantumMechanics.*
<1> yeah, that's part of j2se now
<4> use a security manager to restrict access to ssl encrypted data using SOAP? no problem.
<4> sort a hashmap? Jump through hoops, bitch.
<1> well, for the simple stuff it's because there are like 800 similar things
<1> java.****me.bananas is the same as java.****me.apples but the latter one doesn't allow the letter 'b'
<0> yeah... I took a Java course in college - didnt like it AT ALL
<5> Poutine you about?
<4> evulish_: of which 481 are deprecated
<0> what's the best way to structure a db UPDATE statement to only update the table field if the user has populated the html form field ?
<4> uh
<4> by using an if statement?
<0> doh!
<4> if ispopulated(thehtmlformfield){ doUpdateSQLstatement() }
<4> pseudocode there, of course
<0> yeah... but I'll need to place my if's inside the UPDATE statement
<4> why?
<4> sounds like bad design practice to me
<0> well because.... the update statement will be dynamically generated
<4> why?
<0> based on which form fields are populated
<4> sounds like bad design to me.
<0> I dont want to update a db field if the html form field has not been populated
<4> then don't
<4> use a block of if statements to test each form field
<4> and dynamicly build an UPDATE sql string
<4> and keep track of whether you added ANYTHING to the sql string or not, and if not, then don't run the update
<0> so you're saying use multiple UPDATE statements ?
<4> no
<4> one update statement
<4> build it dynamically
<4> sqlstring = "UPDATE table ";
<0> right
<0> a series of if statements to create the string
<4> if if ispopulated($thehtmlformfield_userename){ sqlstring .= " SET username=$thehtmlformfield_username"}
<0> and then run the string
<4> etc
<4> yeah
<0> if I'm using switch statements instead of if statements, is this valid? case isset:
<0> or do I need to say case isset($_POST['var']):
<0> so far I have switch ( $_POST['var'] ) {
<4> sure
<4> just don't break
<0> is it efficient to use switch statements with isset ?
<4> sure
<4> regardless of efficiency, it's pretty much the only way to do it
<0> so case isset: is valid ?
<0> without using brackets or anything?
<4> what would you need brackets for?
<0> ie. case isset():
<0> or case isset($_POST['var']):
<4> I'm not following you
<4> as opposed to what?
<0> case isset:
<6> isset what?
<4> isset is a function
<0> will case isset: give me an error?
<4> and () aren't brackets
<4> they're parenthesis
<4> of course it will
<0> haha... yeah that's what I meant
<0> well... if I have to name the variable twice then is it not more efficient (less typing) to just use an if statement?
<4> um
<4> more efficient does not mean less typing
<0> or does the switch statement execute faster ?
<4> I think you need to re-read what a switch statement does.
<0> I know what it does
<4> obviously not
<4> switch takes a variable
<4> and then case statements test values against that variable
<0> yes I know
<4> ok
<6> where are you testing against a value?
<0> same thing can be accomplished using an if
<4> roughly but switches are more efficient
<0> faster execution time right?
<6> better to use a switch than a bunch of if/else statements
<4> yes
<4> and readability
<4> and also switches provide an easy mechanism for an exclusive selection of a single pathway
<0> yeah.. thought so
<4> switch($_POST['val']) { case '3': { dostuff(); break;} case '4': { doOtherStuff(); break;}}
<4> etc
<0> so if I have switch ( $_POST['var'] ) { case isset($_POST['var']: $num_populatedfields++; break; }
<0> that is fine?
<4> no
<4> thats wrong
<4> thats essentially saying if $_POST['var'] == isset($_POST['var'])
<4> which makes no sense at all
<4> and again shows me you have no grasp of what a switch statement does
<0> ok so then I cant use switch statements for what I'm trying to do
<0> I just want to say "if the variable is set increment a different variable"
<0> thought I could do it using switch statements
<4> nope
<0> k.. my bad
<6> do your form fields match your sql column names?
<4> http://www.cafepress.com/buy/Cat/-/pv_design_details/pg_4/id_8143964/opt_/fpt_/c_/hlv_t
<6> sweet
<0> ummm.... nope
<4> hehe
<0> Robdgreat: and if they do?
<6> you could do a foreach($_POST as $key=>$value) { if(isset($_POST['key'])) { $query .= "$key=$value"; } }
<6> well
<6> something similar to that
<4> oh yeah
<6> It's late, I'm half asleep
<4> that's an awesome way to introduce some good SQL injection too.
<4> :P
<6> sssshhhh
<6> you're ruining my evil plan, biatch
<4> Sorry, I forgot that you were trying to take over the world today.
<6> no problem
