Twitter Bootstrap Question posted in

Dynamically create a grid layout using div tag in PHP-Twitter bootstrap

So I have a question similar to this one but I’m applying it only in vanilla PHP and not in wordpress. After countless hours of struggle I finally got the answer but somehow if I increase the size of my grid number the items are not aligning.

I want it to look like this:

-----------
- 1 2 3 4 -
-----------

But:
As stated on my problem if I tried to increase the grid (or more precisely the item) it becomes like this:

-----------
- 1 2 3 4 -
-   5     -
-6        -
-7        -
-----------

It becomes cluttered. Below is the code that I’m trying to experiment.

<div class="container">
<?php
$i=0;
$item=0;
$html_tag = '<div class = "row"><div class="col 3">';

while($item <= 4)
{
?>
    <?php if($i % 4 == 0) {
        $html_tag .= 'col '.$i.'</div>';
    }
    else {
        $html_tag .= '<div class="col"> col '.$i.'</div>';
    }
    ?>
<?php
    $i++;
    $item++;
}
$html_tag .= '</div>';
?>

<?php echo $html_tag ?>

P.S. I’m using twitter bootstrap 4 for it’s responsiveness.

EDIT:

Notice the screenshot below, I just realized that there is an extra text which is ‘col ?3’ inside the div row instead of another div column (which wasn’t created).

    You should inspect your code, the final structure is not correct.

    This is what you got

    <div class="container">
    <div class="row">
        <div class="col 3">col 0</div>
        <div class="col"> col 1</div>
        <div class="col"> col 2</div>
        <div class="col"> col 3</div>
        col 4
    </div>
</div>

    Try with this code

    $html = '';
$totalItemPerLine = 3;
$totalItem = 7;
for($i = 0; $i < $totalItem; $i++)
{
    if($i % $totalItemPerLine == 0)
    {
        $html .= '<div class="row">'; // OPEN ROW
    }

    $html .= '<div class="col"> col '.$i.'</div>';

    if($i % $totalItemPerLine == ($totalItemPerLine-1))
    {
        $html .= '</div>'; // CLOSE ROW
    }
}

echo $html;

    NOTE: You could do exactly the same with a while, but I used a for for the readability

    EDIT:

    Based on your comment @DavidDiaz this is the code directly with HTML
    But I recommend you to learn POO and use class to do this page

    $html = '';
$totalItemPerLine = 3;
$totalItem = 7;
for($i = 0; $i < $totalItem; $i++)
{
    if($i % $totalItemPerLine == 0)
    {?>
        <div class="row"> <!-- OPEN ROW -->
    <?php } ?>

    <div class="col"> col <?= $i ?> </div>

    <?php if($i % $totalItemPerLine == ($totalItemPerLine-1))
    { ?>
        </div> <!-- CLOSE ROW -->
    <?php }
} ?>

    Something wrong with the accepted answer. It doesn’t close the last row. It needs another condition.

    $html = '';
$totalItemPerLine = 3;
$totalItem = 7;
for($i = 0; $i < $totalItem; $i++)
{
    if($i % $totalItemPerLine == 0)
    {
        $html .= '<div class="row">'; // OPEN ROW
    }

    $html .= '<div class="col"> col '.$i.'</div>';

    if($i % $totalItemPerLine == ($totalItemPerLine-1) || $i == ($totalItems-1))
    {
        $html .= '</div>'; // CLOSE ROW
    }
}

echo $html;
