Description

A Laravel package that aids in generation of tag clouds

Installation

Install this package through Composer. To your composer.json file, add:

    "lithiumdev/laravel-tagcloud": "~1.0"

Next, run the Composer update comand

$ composer update

Add the service provider to app/config/app.php, within the providers array.

    'providers' => array(
        // ...
        LithiumDev\TagCloud\ServiceProvider::class,
    ),

Usage

use LithiumDev\TagCloud\TagCloud;

$cloud = new TagCloud();
$cloud->addTag("tag-cloud");
$cloud->addTag("programming");

echo $cloud->render();

Or:

// Assumes use of Facade "TagCloud"
$cloud = \TagCloud::addTags(['tag_1', 'tag_2', 'tag_3']);

echo $cloud->render();

Convert a string

$cloud->addString("This is a tag-cloud script!");

Adding multiple tags

$cloud->addTags(array('laravel', 'laravel-tagcloud','php','github'));

Removing a tag

$cloud->setRemoveTag('github');

Removing multiple tags

$cloud->setRemoveTags(array('tag','cloud'));

More complex adding

$cloud->addTag(array('tag' => 'php', 'url' => 'http://www.php.net', 'colour' => 1));
$cloud->addTag(array('tag' => 'ajax', 'url' => 'http://www.php.net', 'colour' => 2));
$cloud->addTag(array('tag' => 'css', 'url' => 'http://www.php.net', 'colour' => 3));

Set the minimum length required

$cloud->setMinLength(3);

Limiting the output

$cloud->setLimit(10);

Set the order

$cloud->setOrder('colour','DESC');

Set a custom HTML output

$cloud->setHtmlizeTagFunction(function($tag, $size) use ($baseUrl) {
  $link = '<a href="'.$baseUrl.'/'.$tag['url'].'">'.$tag['tag'].'</a>';
  return "<span class='tag size{$size} colour-{$tag['colour']}'>{$link}</span> ";
});

Outputting the cloud (shown above)

echo $cloud->render();

Transliteration

By default, all accented characters will be converted into their non-accented equivalent, this is to circumvent duplicate similar tags in the same cloud, to disable this functionality and display the UTF-8 characters you can do the following:

$tagCloud->setOption('transliterate', false);
