Good afternoon could explain in detail how to insert the code in the different sections of a template. as I try to do it and it gives me ERROR 500 in my browser.


<?php echo show_banner( {1} ); ?>
<?php echo show_banner( '{TODAS LAS CATEGORIAS}' ); ?>

You should replace {banner} with ID, not with {ID}

<?php echo show_banner(1); ?>
<?php echo show_banner('my_short_name'); ?>
