Getting loopy

bweekly

Can someone assist with this code? What I want to do is build a table by looping through data. The table should be four cells across, then end with a </tr> tag, switch background color for another four cells, etc., to the end of the data. The code below iterates four proper cells, spits out a </table>, then four lines w/o table information (it is counting correctly), then another proper four cells, etc.. Maybe I'm tired....

<?php

$tdcount = 1;
$numtd = 4;
$numrow =5;

echo "<table width=100%>";

for($i=0;$i<$numrow;$i++){

//define which colors for even and odd line numbers

if($i % 2 == 0) {
$bgcolor='#f3f3f3';
} else {
$bgcolor='#e3e3e3';
}

if ($tdcount == 1) echo "<tr bgcolor=$bgcolor>";
echo "<td>[data]</td>";
if ($tdcount == $numtd) {
echo "</tr>";
$tdcount = 1;
} else {
$tdcount++;
}

if ($tdcount!= 1) {
while ($tdcount <= $numtd) {
echo "<td>[data]</td>";
$tdcount++;
}
echo "</tr>";
}
echo "</table>";
}

 $countdata=20;
$tdrow=4; 
$bgcolor1="#f3f3f3";
$bgcolor2="#e3e3e3";
$bgcolor=$bgcolor1;
echo '<table width=100%><tr bgcolor="'.$bgcolor.'">'; 

for($i=0;$i<$countdata;$i++){ 

//define which colors for even and odd line numbers 
if ($i % $tdrow == 0 && $i!=0)
	{
	$bgcolor=($bgcolor==$bgcolor1)?$bgcolor2:$bgcolor1; 
	echo'</tr><tr bgcolor="'.$bgcolor.'">';
	}	

echo "<td>[data]</td>"; 

}
echo "</tr></table";

I haven't tested this but here's my take on your code

I've assumed that you're working from a database result set, could be from an array though.

<?php
$tdcount = 0;
$numtd = 4;
$toggle = 0;

echo "<table width=100%>";

while( $row = mysql_fetch_array( $result))
{
    // define which colors for even and odd line numbers

if ( ($tdcount % $numtd) == 0)
{
  $bgcolor = ( $toggle == 0)?'#f3f3f3':'#e3e3e3';
  $toggle = 1 - $toggle;
  echo "<tr bgcolor='{$bgcolor}'>";
}
echo "<td>{$row['stuff']}</td>";
if ( ($tdcount % $numtd) == $numtd -1) echo "</tr>";
$tdcount++;
}
echo "</table>";
?>

Many thanks. It seems the simpler the code the better it works....
