Insert tr after every third loop












7















I'm making a forum in PHP. I have to display all forum categories in a table, and to do so, I have used a while loop. However, I want to have only 3 td's in every table row. To loop through the categories, I'm using a while loop with the query, so I don't think I can use modulus here.

  • You could use the modulus operator % by simply creating an increment variable $i=0 prior to the loop and incrementing it ++$i in each iteration of the while loop.

Why can't you use modulus? Just add a counter somewhere, and if it hits % 3 == 0 reset the counter and do your stuff.



You might need to do some extra if's for first and last and stuff like that, but there is no reason not to use a modulo with a while.



$i=0;

while(guard()){

    if($i % 3 == 0){

       //ploing

    }

 $i++

}

This code will close any extra rows:



<table>

<?php

$columns = 3;

$i = 0;

while($row = mysql_fetch_array($result)){

    $i++;

    //if this is first value in row, create new row

    if ($i % $columns == 1) {

        echo "<tr>";

    }

    echo "<td>".$row[0]."</td>";

    //if this is last value in row, end row

    if ($i % $columns == 0) {

        echo "</tr>";

    }

}

//if the counter is not divisible by the number of columns, we have an open row

$spacercells = $columns - ($i % $columns);

if ($spacercells < $columns) {

    for ($j=1; $j<=$spacercells; $j++) {

        echo "<td></td>";

    }

    echo "</tr>";

}

?>

</table>

I haven't tested the code, but the logic should work:



<Table>

<?php

$i = 0;

while($row = mysql_fetch_array($result)){

    if($i == 0){

        echo"<TR>";

    }

    echo"<td>".$row[0]."<TD>";

    $i++;

    if($i == 3)

    {

        $i = 0;

        echo"</tr>"

    }

}

if($i ==1){

    echo "<td></td><td></td></tr>";

}

if($i ==2)

{

    echo "<td></td></tr>";

}

?>

        I haven't tested the code, but the logic should work:



        <Table>
        
<?php
        
$i = 0;
        
while($row = mysql_fetch_array($result)){
        
    if($i == 0){
        
        echo"<TR>";
        
    }
        
    echo"<td>".$row[0]."<TD>";
        
    $i++;
        
    if($i == 3)
        
    {
        
        $i = 0;
        
        echo"</tr>"
        
    }
        
}
        
if($i ==1){
        
    echo "<td></td><td></td></tr>";
        
}
        
if($i ==2)
        
{
        
    echo "<td></td></tr>";
        
}
        
?>
        
<table>
