Please familiarize yourself with our updated Themer’s Guide if you haven’t already done so (as a few things have recently changed).
Then, please copy wootickets/views/tickets.php and place your copy in YOUR_THEME/events/tickets.php.
Locate this section:
woocommerce_quantity_input( array( 'input_name' => 'quantity_' . $ticket->ID,
'input_value' => 0,
'min_value' => 0,
'max_value' => $product->backorders_allowed() ? '' : $product->get_stock_quantity(), ) );
And change ‘input_value’ => 0 to ‘input_value’ => 1 instead (1 being the default value the quantity selector will then use).
Important! We are shortly going to release a maintenance release at which point the above approach will not work. So if you find that is the case please move your template override from:
YOUR_THEME/events/tickets.php
To:
YOUR_THEME/tribe-events/wootickets/tickets.php
And you should find your customization comes back to life. You could of course set it up in both locations right from the start, in which case the customization will carry over without interruption.
I hope that all makes sense but please just let me know if it does not.
