Question

I’m going to get a headache from this one. I have a simple query and a simple table I generate during the query’s while loop. I want to create a new row after each third result.

$customers_num=8; // This is actually mysql_numrows($result) never mind; 

$i=0;
while ($i < $customers_num) {
    if($i % 3 === 0) {
        print '<tr>';
    }

    print '<td style="width: 30%;"></td>';

    if($i % 3 === 0) {
        print '</tr>';
    }

    $i++;
}

If the question is not clear, because of my English, I could try to improve the question to bee more precise.

The problem is that I close the <tr> right after I open it :S I need to open it, put three TD’s into it, and then close it…

First of all, you forgot to increment $i. This should do the trick:

$customers_num=8; // This is actually mysql_numrows($result) never mind; 

$i=0;
while ($i < $customers_num) {

    if($i % 3 === 0) {
        if ($i > 0) print "</tr>"; //not first row
        if ($i < $customers_num - 1) print '<tr>'; //not last row
    }

    print '<td style="width: 30%;"></td>';

    $i++;
}
