How to Create a Word Cloud

Follow the directions below to create a word cloud on a page. Check out our own Word Cloud page.

Add word cloud shortcode

You can either insert this in the Code Snippets plugin (recommended), a child theme's functions.php, or your own custom plugin. The Code Snippets plugin is the recommended option.

add_shortcode( 'word-cloud', 's11_word_cloud' );

function s11_word_cloud( $atts ) {

	$atts = shortcode_atts( array(

		'words' => 'Awesome, Fabulous',

		'colors' => '#21759b, #d54e21, #464646',

	), $atts );

	$colors = explode( ',', $atts['colors'] );

	$words = array_filter( explode( ',', $atts['words'] ) );

	$words = array_map( 'strtolower', array_map( 'trim', $words ) );

	$words = array_map( 'ucwords', $words );

	$word_counts = array_count_values( $words );

	$sorted = $word_counts;

	arsort( $sorted );

	$highest_count = reset( $sorted );

	$max_size = 75;

	$min_size = 10;

    $step = absint( ( $max_size - $min_size ) / $highest_count );

	$weighted = array();

	foreach( $word_counts as $word => $count ) {

		$weighted[ $word ] = $min_size + ( $step * $count );

	}

	$color_pointer = 0;

	$all_words = array();

	$cloud = '<ul class="s11cloud">';

	foreach ( $weighted as $word => $size ) {

		$all_words[] = '<li style="font-size:' . absint( $size ) .'px;color:' . esc_attr( $colors[ $color_pointer ] ) .'">' . trim( $word ) . '</li>';

		$color_pointer++;

		if ( ! isset( $colors[ $color_pointer ] ) ) {

			$color_pointer = 0;

		}

	}

	shuffle( $all_words );

	$cloud .= implode( ' ', $all_words );

	$cloud .= '</ul>';

	s11_add_cloud_style( $cloud );

	return $cloud;

}

function s11_add_cloud_style( &$cloud ) {

	$cloud .= '<style>ul.s11cloud {

    	max-width: 500px;

    	padding: 30px 10px;

    	text-align:center;

		margin:0 auto;

		line-height: 1;

	}

	.s11cloud li{

		display:inline-block;

		list-style:none;

		padding-right:3px;

	}

	</style>';

}

Create Form to collect words

First, create a form with a field that will collect the entries that you want to be displayed in the word cloud. You can either have your users submit entries to your form or import your own entries via CSV.

Create View to display the word cloud

Now that you have a form set up, start with the instructions to create a view.

In the Before Content box, add the following:

[word-cloud words="

In the Content box:

[125],

Replace 125 with the ID or key of your word

After Content box:

"]

Click Update to save your View and publish it on a page. When the page is visited, it should look something like this:
