PHP Wrapping custom items inside loop Wordpress - php

Question

I am currently creating a slider which consists of products.
Currently I have managed to wrap every 2 items in div using this code:
<div class="frame crazy" id="crazy">
<div class="slidee">
<?php if ( $myposts->have_posts() ) :
$i = 0;
while ( $myposts->have_posts() ) : $myposts->the_post();
$image = wp_get_attachment_image_src( get_post_thumbnail_id( get_the_id() ), 'single-post-thumbnail' );
$value = get_field( "alternate_image", get_the_id() );
$titl = get_field( "title", get_the_id() );
$big = get_field( "big_section", get_the_id() );
if ( $i % 2 == 0) : ?>
<div class="op" <?if ($big==1){?>style="width:850px !important;"<?}?>>
<?php endif;
$_pf = new WC_Product_Variable(get_the_id());
$variations = $_pf->get_available_variations();
$vrt = count($variations);
?>
<div data-hv="<?php echo $value; ?>" data-titleContent="<a href='<?php echo get_the_permalink();?>'><?php echo get_the_title(); ?></a>" data-tipso-content="<span class='varaition'>this item has <?php echo $vrt; ?> variation(s)</span><a class='bty' href='<?php echo get_the_permalink(); ?>'>details</a>" data-url="<? echo the_permalink(); ?>" class="cola <?php if($big==1){?>big<?}?>" style="background-image: url('<?php echo $image[0]; ?>')" data-mg="<?php echo $image[0];?>">
<?php if($titl==1) { ?>
<h2><a href='<?php echo get_the_permalink();?>'><?php echo get_the_title(); ?></a></h2>
<p class="slu"><a href='<?php echo get_the_permalink();?>'>shop now ></a> </p>
<?php } ?>
</div>
<?php if ( $i % 2 != 0 ) : ?>
</div>
<?php endif; ?>
<?php $i++; endwhile; ?>
<?php if ( $i % 2 != 0 ) : ?>
</div>
<?php endif; ?>
<?php endif;?>
</div>
</div>
This code wraps every two products like this:
<div class="op">
<div class="product1">
//content
</div>
<div class="product2">
//content
</div>
</div>
<div class="op">
<div class="product3">
//content
</div>
<div class="product4">
//content
</div>
</div>
But I need to fetch custom number of posts according to product meta. So that the number of products can be varying like this:
<div class="op">
<div class="product1">
//content
</div>
<div class="product1">
//content
</div>
<div class="product1">
//content
</div>
<div class="product1">
//content
</div>
<div class="op">
<div class="product1">
//content
</div>
<div class="product1">
//content
</div>
</div>
Is it possible using product meta or any better idea?

Answer 1

this line in your code:
if ( $i % 2 == 0) : ?>
contains the loop number, change that to be a variable and set that variable from the meta data, so:
$loopmeta=metadata_retriever();
if ( $i % $loopmeta == 0 ) : ?>
You will have to write the metadata_retriever() function and put some error checking around the retrieval of the $loopmeta variable to ensure it comes back as a valid integer (not 0, nor 12.735 for instance :-) )
