Alternating Row Color

[Sethm]

I want to set up my rows to display so based on their id's they can have a light grey background or white - just for organization purposes.

 

Does anyone have an idea how I would go about this using PHP scripting?

 

Thanks in advance!

You want to use the modulus ( % ) operator.

 

$i=0;
$x = 10;
while ($i < $x) {
    if (($i % 2) == 0) 
           echo "White <br />";
   else 
           echo "Grey <br />";
    $i++;
}

 

Is a rough example of how you would use it.

Sweet!

Thank you!

 

I'll mark it solved when I finally figure out if it works!

<tr class="<?php echo ($i++ % 2) ? 'odd' : 'even'; ?>">

Use this for your row. It will alternate between the classes odd and even, so just style those two classes in your css and you should be fine

Jay,

The method you gave me worked quite smoothly.  I was a bit confused with the other one. I was trying to wrap my head around it and would have loved to understand it, but the way you presented it worked without me thinking so thank you for helping me.

 

When I get more time and don't have to slam things together I will have to learn what the modulus operator is and how it really functions - so thank you Premiso for pointing me in the right direction!

Well not to throw you in the deep end but the real magic is the ternary operator in that code

Is that the two ++ signs? ...guess I could search it out. Thanks - I'm slowly learning this PHP coding thing. It's a process - but I have to admit ..it is fun!

No it's the ? and the : that make a small shorthand "if" statement. It's the same as having

if($i++ % 2) {
    echo 'odd';
}else{
    echo 'even';
}

That does sound extremely useful and simple. Thanks for the short lesson! You're a good sport!
