Limit number of products for compare

Hello there,

I would like to limit the compare product to 3. How can be done this in current compare.php? or somewhere else?

Thanks

Hi,

Try to add the following PHP code snippet to the child theme functions.php file to do this

function woodmart_get_compared_products_table() {
	$products = woodmart_get_compared_products_data();
	$fields = woodmart_get_compare_fields();
	$empty_compare_text = woodmart_get_opt( 'empty_compare_text' );
	?>
	<div class="woodmart-compare-table">
		<?php
		if ( ! empty( $products ) ) {
			array_unshift( $products, array() );
			foreach ( $fields as $field_id => $field ) {
				if ( ! woodmart_is_products_have_field( $field_id, $products ) ) {
					continue;
				}
				?>
					<div class="woodmart-compare-row compare-<?php echo esc_attr( $field_id ); ?>">
						<?php $i = 0; ?>
						<?php foreach ( $products as $product_id => $product ) : ?>
							<?php if ( $i > 3 ) : ?>
								<?php continue; ?>
							<?php endif; ?>
							<?php if ( ! empty( $product ) ) : ?>
								<div class="woodmart-compare-col compare-value" data-title="<?php echo esc_attr( $field ); ?>">
									<?php woodmart_compare_display_field( $field_id, $product ); ?>
								</div>
							<?php else: ?>
								<div class="woodmart-compare-col compare-field">
									<?php echo esc_html( $field ); ?>
								</div>
							<?php endif; ?>
						<?php $i++; ?>
						<?php endforeach ?>
					</div>
				<?php
			}	
		} else {
			?>
				<p class="woodmart-empty-compare woodmart-empty-page">
					<?php esc_html_e('Compare list is empty.', 'woodmart'); ?>
				</p>
				<?php if ( $empty_compare_text ) : ?>
					<div class="woodmart-empty-page-text"><?php echo wp_kses( $empty_compare_text, array('p' => array(), 'h1' => array(), 'h2' => array(), 'h3' => array(), 'strong' => array(), 'em' => array(), 'span' => array(), 'div' => array() , 'br' => array()) ); ?></div>
				<?php endif; ?>
				<p class="return-to-shop">
					<a class="button" href="<?php echo esc_url( wc_get_page_permalink( 'shop' ) ); ?>">
						<?php esc_html_e( 'Return to shop', 'woodmart' ); ?>
					</a>
				</p>
			<?php
		}
		?>
	</div>
	<?php
}

Hello Artem,

The function is only hiding the products that are extra e.g. 4th, 5th, etc. But I can still add products to compare and I see on the menu bar that there are more than 3 products for compare.

Sorry, but there is no option in our theme to limit the number of products in the compare completely, unfortunately.

Any plans to add it in the future?

Currently, we don’t have such plans. We will consider this as a feature request for our future updates.

In this case:

Can you point me which file I can edit on my own in order to limit adding items to 3?

Sorry, but there is no such mechanism that you can simply change to 3. We don’t have instruction about this additional customization.

I understand that. I just ask which if you suggest me to edit in order to do it myself, like compare.php and/or function.php, etc..?

It may require a lot of files to customize. It is not just a single place and we don’t have a complete instruction, unfortunately.
