PDO MySQL product loop - php

Question

Im a real beginner when it comes to queries and PDO, i need some assistance in a project i am busy with. What i want to accomplish is to display products from the database. However the template style i am using forces me to show 3 products per row, is there a way to show 3 products per row and loop the code once there is more than 3 (if there is 5 products, the first 3 will display in the first row, and the rest in the second).
Here is the template i am using, note the div class "top-box", this forces that only 3 products can be shown per row.
<div class="top-box">
<?php
$sql = "SELECT * FROM _products WHERE category = '$cat'";
$result = dbConnect()->query($sql);
// If the SQL query is succesfully performed ($result not false)
if($result !== false) {
$cols = $result->columnCount(); // Number of returned columns
// Generate ADS Feed for each ROW
foreach($result as $row) {
echo '<div class="col_1_of_3 span_1_of_3">
<a href="product.php?i=' . $row['model'] . '">
<div class="inner_content clearfix">
<div class="product_image">
<img src="images/' . $row['model'] . '.jpg" alt=""/>
</div>
<div class="price">
<div class="cart-left">
<p class="title">' . $row['name'] . '</p>
</div>
<div class="clear"></div>
</div>
</div>
</a>
</div>';
}
} else {
echo "<p>No products available at this moment, contact us for more information!</p>";
}
?>
<div class="clear"></div>
</div>

Answer 1

You can solve it like this:
<?php
if ($counter % 3 == 0 && $counter!=$total_row_fetched) {
echo '<div class="clear"></div>';
echo '</div>';
echo '<div class="top-box">';
}
if($counter==$total_row_fetched){
echo '<div class="clear"></div>';
echo '</div>'; // it will close the last open div
}
++$counter;
?>

You can use a count variable inside your products foreach-loop. Every three products you can close the top-box and open a new one (This is an assumption as I don't know exactly how your styles work).
At the end of the foreach-loop:
if ($count != 0 && $count % 3 == 0) {
echo '<div class="clear"></div>';
echo '</div>'; // close last .top-box
echo '<div class="top-box">';
}
++$count;
I don't see how your question is connected to PDO. Keep in mind that using unescaped variables inside a query is potentially dangerous. Have a look here for some help: https://stackoverflow.com/a/60496/2516377

Add a counter and use % arithmetic operator to calculate column number.
$counter=0;
foreach (...) {
$column_number=$counter % 3;
$counter++;
}
