Get a barcode using php without using a shortcode?

Hi,

To output a barcode image, you can do this:

$ean = alg_wc_ean()->core->get_ean( $variation_id );
echo alg_wc_ean()->pro->barcode_generator->get_barcode_img( $ean, array( 'dim' => '2D', 'w' => 2, 'h' => 2 ) );

P.S. I know you said “without using a shortcode”, but just in case – we can achieve the same with:

echo do_shortcode( '[alg_wc_ean_barcode_2d product_id="' . $variation_id . '"]' );

Hope this helps. Please let me know if you have any questions.
