Create Bandcamp shortcode from Jetpack files!
-
Hi
We are using Jetpack because it seems to be the only plugin which enables a Bandcamp shortcode.
But it is a bit like using dynamite to crack a walnut!
Looking at JetPack they have a php file which creates a shortcode handler for the shortcode.<?php // shortcode handler for [bandcamp], which inserts a bandcamp.com // music player (iframe, html5) // // [bandcamp album=119385304] // [bandcamp album=3462839126 bgcol=FFFFFF linkcol=4285BB size=venti] // [bandcamp track=2446959313] // function shortcode_handler_bandcamp( $atts ) { // there are no default values, but specify here anyway // to explicitly list supported atts $attributes = shortcode_atts( array( 'album' => null, // integer album id 'track' => null, // integer track id 'video' => null, // integer track id for video player 'size' => 'venti', // one of the supported sizes 'bgcol' => 'FFFFFF', // hex, no '#' prefix 'linkcol' => null, // hex, no '#' prefix 'layout' => null, // encoded layout url 'width' => null, // integer with optional "%" 'height' => null, // integer with optional "%" 'notracklist' => null, // may be string "true" (defaults false) 'tracklist' => null, // may be string "false" (defaults true) 'artwork' => null, // may be string "false" (alternately: "none") or "small" (default is large) 'minimal' => null, // may be string "true" (defaults false) 'theme' => null, // may be theme identifier string ("light"|"dark" so far) 'package' => null, // integer package id 't' => null, // integer track number 'tracks' => null, // comma separated list of allowed tracks 'esig' => null // hex, no '#' prefix ), $atts, 'bandcamp' ); $sizes = array( 'venti' => array( 'width' => 400, 'height' => 100 ), 'grande' => array( 'width' => 300, 'height' => 100 ), 'grande2' => array( 'width' => 300, 'height' => 355 ), 'grande3' => array( 'width' => 300, 'height' => 415 ), 'tall_album' => array( 'width' => 150, 'height' => 295 ), 'tall_track' => array( 'width' => 150, 'height' => 270 ), 'tall2' => array( 'width' => 150, 'height' => 450 ), 'short' => array( 'width' => 46, 'height' => 23 ), 'large' => array( 'width' => 350, 'height' => 470 ), 'medium' => array( 'width' => 450, 'height' => 120 ), 'small' => array( 'width' => 350, 'height' => 42 ) ); $sizekey = $attributes['size']; $height = null; $width = null; $isVideo = false; // Build iframe url.

"px"; } if ( ! $width ) { $width = $sizes[ $sizekey ]['width']; $csswidth = $width .
