Re: [PHP] how to say inverse your value (to a boolean)?
way to do
it.
I have found, in a number of cases, that using only the TR tag
doesn't work all the time.

No need to initialize $dr as by default PHP will make it a
boolean false,
then each itteration, it will toggle true/false and
substitute the CSS class

?php
$arr = range(1, 10);
$i = 0;
foreach ( $arr AS $row ) {
$row_color = ( ( $i++ % 2 ) ? 'green' : 'red');
echo $row_color;

another (neat|strange)+ way I use the above is like so
style
.rowColor0 { background: #FF; }
.rowColor1,
.rowColor3 { background: #EE; }
.rowColor2 { background: #DD; }
/style
?php
$arr = range(1, 10);
$i = 0;
foreach ( $arr AS $row ) {
echo 'trtd class=rowColor'.( $i++ % 4
).'''.$row.'/td/tr';
}

Re: [PHP] how to say inverse your value (to a boolean)?
thats why I decided years ago to write myself a little bunch of classes for the html tags which gives me the ability to have PHP only code, very nice, no errors and my outputs dont even need Tidy pure XHTML i find these idear of mixing html and php as spagetty, using divs for tables as something what facirs do, no problems with unexpected header outputs, no small fat grafic designer can make my live difficult, I can change evrything on the fly. pure OOP one final echo $page-toHtml(); put a candle for the invention of OOP ... better as sex makes the nights fun consider this guys ralph_def...@yahoo.de tedd tedd.sperl...@gmail.com wrote in message news:p06240800c6a892b12...@[192.168.1.100]...

I tend to do something like this:
$count = 0;
foreach($foo_array as $foo)
{
$class = ($count % 3 == 0)?'class=thirdRow':'';
print tr $classtd$foo/td/tr;
}
You only need to give one row the class, as you style up all the rows
and only change the row that needs to change.

Re: [PHP] how to say inverse your value (to a boolean)?
seems they changing idears on the fly? could it be that the designer is a
smal ugly person while u a a good looking ladykiller ?
on that background I would design a function where u can change ti what ever
u want on the fly something like this
var $a;
function alternate( $a, $_b=array( red, red ,green ,... ) {
if( count( $_b ) $a ) {
return $_b[ $a++ ] ;
}
$a=0;
return $_b[ $a++ ] ;
}
so now u can do what ever anybody wants on just putting the right values
into the array

However, my solution (after reading others) is for an alternating row
color (a boolean operation).
The problem was NOT making every third row a different color or
making every row a different color. Those problems would require
different solutions.
There is nothing wrong with embedding php within html, which is
really a misnomer because it's the php interpreter that's sending the
resultant html to the browser. It is not sending php snip-its for the
browser to handle. So, embedding code such as:
tr class=row?php echo($i++ 1);?
Is a valid statement that works. It would be nice if you initialize
the $i value, but it will work either way.
My solution, provided via the above link, is a valid solution.
Cheers,
tedd

Actually it's the wrong way to do it.
Change the class names to alternate1 and alternate2 (or something
else meaningful without being tied to a definition). That way when you
set the colour for style white to green it doesn't result in
confusion. Seriously though... this is nomenclature 101.

Re: [PHP] how to say inverse your value (to a boolean)?
What a lot of good ideas spawned from the OP!
I am learning many things,.. while also actually working (paying
bills), so I regularly have to just go with what I know well.
Anyway, I already have the forearch { loop (for other reasons it is
necessary), and I only needed one color to alternate with the default
white.. so I used this:
forearch { ...
$tableRowBGcolorBoolCounter = !$tableRowBGcolorBoolCounter; //-boolean
on and off
(which then sticks in one CSS class or another for that tr.

Wow, were to start with all the problems in the above code:
1. Short tags?
Nothing wrong with them. Do yourself a test. There is zero speed difference
in a page. It makes your code cleaner and easier to read, plus less
kilobytes you have to pull from the hard drive, therefore faster pages.
http://stackoverflow.com/questions/662891/is-there-a-speed-difference-betwee
n-php-echo-var-and-var
http://cubicspot.blogspot.com/2009/06/maximum-failure-php-6-deprecates-short
.html
Are you sure you're not confused with short_open_tags ie. ? ? -- which I
am fully against (as am I against % % too), although sadly they are lumped
into the same directive, when IMHO they should be separate.
http://us.php.net/manual/en/ini.core.php#ini.short-open-tag
http://www.php.net/~derick/meeting-notes.html#remove-support-for-and-script-
language-php-and-add-php-var
2. Not using echo or print.
?= ? is a fantastic shortcut to the antiquated ?php echo ; ? B.S.
The vast majority of your page is output in little fragments like this, so
why not keep it clean and easy to read. Why would you purposely choose to be
more verbose than you need to be for something as basic as print.
You actually recommend breaking in/out of php?
Hell yeah I do. THAT is one of the MAIN reasons to use PHP. Otherwise, why
not just render your whole page with a bunch of $html .= 'trtd...';
tags and print $html at the end. Welcome to the year 2000 my friend.
You're probably the same kind of person that does this crap:
if ($foo == true)
{
echo A;
}
else
{
echo B;
}
(complete with extra braces and checking for 'true' explicitly, but not
using === in such cases)
Rather than a much cleaner, easier to read/write and more concise:
?= ($foo) ? 'A' : 'B' ?
3. Using uninitialized variables (I run with the E_ALL crowd)
I'm so happy for you. Do you have a membership card and everything? That's
your own masochistic fault then. I run with the
save-myself-the-headache-and-write-clean-efficient-code crowd.
4. Using the tr class='' and not the td class=''... Hmmm
Maybe you're new to how HTML works, but if you want to highlight a ROW (as
the OP did), then you put the background color on the highest parent that it
applies to. Hey imagine that, there is a TR tag which stands for TABLE ROW
tag. Seems obvious to me. This reduces your page size in kilobytes, makes a
much cleaner HTML rendering to read in source, and is the PROPER way to do
it.

No need to initialize $dr as by default PHP will make it a
boolean false,
then each itteration, it will toggle true/false and

Re: [PHP] how to say inverse your value (to a boolean)?
You can do this...
for( $b=true; your-statement; $b = !$b )
{
your-code
}
I usually use this solution
$types = array( 'one', 'two' );
foreach( $list as $item ) # -- your set of (many) items
{
echo current( $types ); # -- this prints the current class
# code
next( $types ) or reset( $types ); # and this do the magic
}
Hey! look, this solution can work with more than 2 types...
try it with many types: $types = array( 'one', 'two', three', 'four' );

RE: [PHP] how to say inverse your value (to a boolean)?
NO! For the love of God and all that is holy, don't do that accumulator /
mod hack.
That's so 1980's. And why make the CPU do all that math for every row...
Just do this. It's quick and simple:
CSS:
.dataRow1 { background-color: #DFDFDF; }
.dataRow2 { background-color: #FF; }
foreach ($foo_array as $foo) {
?tr class=?= ($dr = !$dr) ? dataRow1 : dataRow2 ?td?= $foo
?/td/tr?php
}
No need to initialize $dr as by default PHP will make it a boolean false,
then each itteration, it will toggle true/false and substitute the CSS class

Re: [PHP] how to say inverse your value (to a boolean)?
Use...
$dr = !$dr
if you want
Notice: Undefined variable: dr
All variables MUST be initialized before using.
If you PHP does not complains about it you should read about error_reporting

RE: [PHP] how to say inverse your value (to a boolean)?
Then YOU have more aggressive error_reporting than the default setting
turned on. You might consider turning it down a notch. NOTICEs are basically
useless and bloat your code IMHO -- and apparently the PHP devs too as per
this...
http://us2.php.net/manual/en/function.error-reporting.php
// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);
Don't tell me what to do! You're not my father! ;-)
http://daevid.com
Some people, when confronted with a problem, think 'I know, I'll use XML.'
Now they have two problems.

Wow, were to start with all the problems in the above code:
1. Short tags?
2. Not using echo or print. You actually recommend breaking in/out of php?
3. Using uninitialized variables (I run with the E_ALL crowd)
4. Using the tr class='' and not the td class=''... Hmmm
}
No need to initialize $dr as by default PHP will make it a boolean false,
then each itteration, it will toggle true/false and substitute the CSS class
