I want to group the result of a sql select in groups of four rows to make dynamically something like this:
<div>
4 rows of the database
</div>
For example, if I have 19 rows in the database, I want to create 4 divs (the last one with the 3 remaining rows). This is for a bootstrap gallery, and the div will have the class .row with 4 columns (the four results from the database). I have 8 images, two divs with the class .row need to be created.
I think this will be achieved with loops, but I can´t find the way.
NOTE: i have coded in a very simplistic way, only to try to explain what I'm looking for. Thanks to all in advance!!
You can make use of the modulus-operator to group your rows into groups of 4, like this:
$i=0;
while($row = ...) {
if($i%4 == 0) { // % = modulus operator. This returns the remainder of a division, so 1%4 = 1 (because it's 0+1/4), while 5%4 also returns 2 (5%4 = 1+1/4)
if($i > 0) {
echo '</div>';
}
echo '<div>';
}
echo $row;
$i++;
}
echo '</div>';
This will group your results in sets of 4 like so: <div>row 1 row 2 row 3 row 4</div><div>row 5 row 6 row 7 row 8</div>
etc.
