dynamic rows and columns inside a foreach loop

[Mad_T]

This works well, but the last 2 cells are missing.
Anyway to dynamically create the missing cells so it looks right ?

<?php

$data = range( '1', '10' );
$numCols = 6;

echo "<table border='1'>\n";
echo "\t<tr>\n";

foreach( $data as $i => $item )
{
    if ( $i != 0 && $i++ % $numCols == 0 )
    {
        echo "\t</tr>\n\t<tr>\n";
    }
    echo "\t\t<td>$item</td>\n";
}

echo "\t</tr>\n";
echo '</table>';
?>

In this example I've got the numCols =6 but that could change, so the additional cells could be more or less.. Any way to make their back ground color different to the filled in cells ?

Thanks 🙂

instead of the foreach() loop through the $data do a loop through the number of columns *2; this way you can check when you have run out of data, and treat the empty cells appropriately.

Thanks for the reply. Sorry for the delay in my reply !

I'm not sure how to do that. can you help ?

Thanks 🙂

something like:

<?php

$data = range( '1', '10' );
$numCols = 6;
$cells=$numCols *2;

echo "<table border='1'>\n";
echo "\t<tr>\n";
for ($i = 1; $i <= $cells; $i++) {

 if ( $i-1==$numCols )
 {
    echo "\t</tr>\n\t<tr>\n";
}

if(isset($data[$i-1])){
 echo "\t\t<td>".$data[$i-1]."</td>\n";
}else{
	 echo "\t\t<td>EMPTY</td>\n";
}


}
echo "\t</tr>\n";
echo '</table>';
?>
