ul class in class-eo-event-list-widget.php

[Ties]

I have a question about the ul class in class-eo-event-list-widget.php. I use the shortcode [eo_events] to display a list of events on my site. Since I wanted it to fit the style of my site, I changed <ul class="%2$s">%1$s</ul> to <ul class="zebra">%1$s</ul>. Works like a charm!
But now I would like to display the same list somewhere else on my site is a different style.

I have two questions:
– what means the %2$s in the original file?
– is there a way to display [eo_events] with different ul classes? Can I implement it in the shortcode for example?

Sorry if the answers are logical, but I’m not so good (yet) in php… Thanks!

Hi,

The %2$s is used inside a sprintf or printf function (see this page). It acts a placeholder. The first argument of those functions takes a string (which will contain those placeholders), subsequent arguments are used as the values of those placeholders. So %1$s will be replaced by the next and %2$s by the following argument. The ‘s’ means string – it can also be ‘f’ for float or ‘d’ for digit.

E.g.

 $num = 5;
 $location = 'tree';
 $format = 'There are %2$d monkeys in the %1$s';
 echo sprintf($format, $location, $num );
 //Prints There are 5 monkeys in the tree

In the particular instance you reference it used as follows;

$html = sprintf($container, $html, esc_attr($args['class']) );

Where $args['class'] contains class name(s) as set here.

Currently there isn’t a way of adding custom classes (but I’m planning on major improvements to template handling in 1.7 – including ‘templates’ for shortcodes, and widgets etc.).

I’d suggest wrapping the shortcode in div element with a certain class and apply the styling that way. In any case – I’d recommend avoiding making any changes to the plug-in code as this will be lost in an update.
