<h3>Usage</h3>
<p>This plugin offers two pieces: a popup, and a ‘card’, or a static poster, from Wikipedia or other wikis that operate on MediaWiki software.</p>
<h4>Adding popups</h4>
<p>To add a popup, while editing a post, surround your text with <code>[wikipopup]</code> shortcode. You can reference a language or a different source, if you’ve set one up.</p>
<p>For example:<br />
– <code>[wikipopup]WordPress[/wikipopup]</code> – Displays a popup from English Wikipedia about the article “WordPress”<br />
– <code>[wikipopup title="WordPress"]This is some text[/wikipopup]</code> – Displays a popup from English Wikipedia about the article “WordPress”, while the trigger text is ‘This is some text’<br />
– <code>[wikipopup title="WordPress" source="ext"]This is some text[/wikipopup]</code> – Displays a popup from the external source you’ve defined as “ext”, about the article “WordPress”, while the trigger text is ‘This is some text’</p>
<p>You can define sources in “Settings -> Wikilookup -> External wikis”.</p>
<h4>Adding cards</h4>
<p>To add a card, while editing a post, add a line with <code>[wikicard title="term"]</code>. You can reference a language or a different source, if you’ve set one up.</p>
<p>For example:<br />
– <code>[wikicard title="WordPress"]</code> – Displays a static card from English Wikipedia about the article “WordPress”.<br />
– <code>[wikicard title="WordPress" lang="es"]</code> – Displays a static card from Spanish Wikipedia about the article “WordPress”.<br />
– <code>[wikicard title="WordPress" source="ext"]</code> – Displays a static card from the external source you’ve defined as “ext”, about the article “WordPress”.</p>
<p>You can define sources in “Settings -> Wikilookup -> External wikis”.</p>
