ijy / EE: Store: Hide modifier option if out of stock
Last active December 18, 2015 20:48
ExpressionEngine: How to conditionally hide modifier options depending on inventory count in Expresso Store 1.6+. {option_stock_level} can be used inside the {modifier_options} tag pair to output the current stock level for that modifier option. It can also be used (as in this example) to conditionally hide modifier options if out of stock.
{modifier_options}
{if option_stock_level > 0}
<option value="{option_id}">
{option_name} {if price_mod_val} ({price_mod}) {/if}
</option>
{/if}
{/modifier_options}

ijy / EE: Dynamic parameter values
Created June 22, 2013 22:41
How to pass in dynamic values to ExpressionEngine tag parameters. (How to use plugin tags inside EE tags). The two secret ingredients are parse="inward" to parse the dynamic inner tag first. The second is the 'random' keyword to ensure the dynamic parameter value is used instead of a placeholder string.
{exp:channel:entries parse="inward" parameter="{exp:plugin:method parameter='value' random}" }

ijy / jquery-pubsub.js
Created June 28, 2013 14:19
jQuery PubSub in three lines. This will work in IE9+, so it's a perfect choice for jQuery 2.0 projects.
var o = $({});
$.subscribe = o.on.bind(o);
$.publish = o.trigger.bind(o);
