[RESOLVED] for each help

Hey, I have a script to display images in an ordered list and then styled to make it look nice. The only problem is that this uses the css property float and I am just using div tags so it messes that up. I was wondering how I would go about creating a foreach statement to create a table 4 columns wide? If I am not being clear just let me know and I will try to explain. Thanks for any help.

I'm not sure if I understand right but you could wrap each element in the foreach loop with <td> tags.

Right, that is pretty much what I am wanting to do, but I also only want 4 images per row and that is the part I don't know how to add to the foreach loop

You'll need two loops for that.


//$items = your array of items
$num_cols = 4;
echo '<table>';
for( $i = 0, $max = count($items) / $num_cols; $i < $max; ++$i ) {
echo '<tr>';
for( $i2 = 0; $i2 < $num_cols; ++$i2 ) {
$current_item = $i * $num_cols + $i2;
if( isset($items[$current_item]) ) {
echo '<td>', $items[$current_item], '</td>';
} else {
echo '<td>&nbsp</td>';
}
}
echo '</tr>';
}
echo '</table>';


Note that the code above is untested but hopefully it helps.

so you only want to go through the foreach loop 4 times?

Use a counter, check when it reached 4, then use "break;" to break out of the loop.

It worked no worries. I'm surprised it did though. Not because of your code, but because I combined two different sets of code and I know pretty much nothing about for statements. Thank you so much for the help. Does anyone know a good place to learn about for statements?

Glad the code helped.

Everything you need to know about for statements can be found in the php manual under control structures.

alright thanx. I was able to understand that code enough to use it for other things so I think I am getting the hang of it. Thanx again
