功能说明

使用最简便的方式,为你的数据模型提供强大「打标签」功能。

:gift: 项目地址: https://github.com/summerblue/laravel-taggable

本项目修改于 rtconner/laravel-tagging项目,增加了一下功能:

  • 标签名唯一;
  • 增加 etrepat/baum依赖,让标签支持无限级别标签嵌套;
  • 中文 slug 拼音自动生成支持,感谢超哥的 overtrue/pinyin;
  • 提供完整的测试用例,保证代码质量。

注意: 本项目只支持 5.1 LTS

:heart: 此项目由 The EST Group团队的 @Summer维护。

无限级别标签嵌套

集成 etrepat/baum让标签具备从属关系。

$root = Tag::create(['name' => 'Root']);// 创建子标签$child1 = $root->children()->create(['name' => 'Child1']);$child = Tag::create(['name' => 'Child2']);$child->makeChildOf($root);// 批量构建树$tagTree = [    'name' => 'RootTag',    'children' => [        ['name' => 'L1Child1',            'children' => [                ['name' => 'L2Child1'],                ['name' => 'L2Child1'],                ['name' => 'L2Child1'],            ]        ],        ['name' => 'L1Child2'],        ['name' => 'L1Child3'],    ]];Tag::buildTree($tagTree);

更多关联操作请查看: etrepat/baum。

标签名称规则说明

  • 标签名里的特殊符号和空格会被 -替代;
  • 智能标签 slug 生成,会生成 name 对应的中文拼音 slug ,如: 标签-> biao-qian,拼音一样的时候会被加上随机值;

标签名清理使用: $normalize_string = EstGroupe\Taggable\Util::tagName($name)。

Tag::create(['标签名']);// name: 标签名// slug: biao-qian-mingTag::create(['表签名']);// name: 表签名// slug: biao-qian-ming-3243 (后面 3243 为随机,解决拼音冲突)Tag::create(['标签 名']);// name: 标签-名// slug: biao-qian-mingTag::create(['标签!名']);// name: 标签-名// slug: biao-qian-ming

安装说明:

安装

composer require estgroupe/laravel-taggable "5.1.*"

安装和执行迁移

在 config/app.php的 providers数组中加入:

'providers' => array(    \EstGroupe\Taggable\Providers\TaggingServiceProvider::class,);
php artisan vendor:publish --provider="EstGroupe\Taggable\Providers\TaggingServiceProvider"php artisan migrate

请仔细阅读 config/tagging.php文件。

创建 Tag.php

不是必须的,不过建议你创建自己项目专属的 Tag.php 文件。

<?php namespace App\Models;use EstGroupe\Taggable\Model\Tag as TaggableTag;class Tag extends TaggableTag{    // Model code go here}

修改 config/tagging.php文件中:

    'tag_model'=>'\App\Models\Tag',

加入 Taggable Trait

<?php namespace App\Models;use Illuminate\Database\Eloquent\Model;use EstGroupe\Taggable\Taggable;class Article extends \Illuminate\Database\Eloquent\Model {    use Taggable;}

「标签状态」标示

Taggable能跟踪模型是否打过标签的状态:

// `no`$article->is_tagged// `yes`$article->tag('Tag1');$article->is_tagged;// `no`$article->unTag();$article->is_tagged// This is fast$taggedArticles = Article::where('is_tagged', 'yes')->get()

首先你需要修改 config/tagging.php文件中:

'is_tagged_label_enable' => true,

然后在你的模型的数据库创建脚本里加上:

<?phpuse Illuminate\Database\Schema\Blueprint;use Illuminate\Database\Migrations\Migration;class CreateArticlesTable extends Migration {    public function up()    {        Schema::create('weibo_statuses', function(Blueprint $table) {            $table->increments('id');            ...            // Add this line            $table->enum('is_tagged', array('yes', 'no'))->default('no');            ...            $table->timestamps();        });    }}

「推荐标签」标示

方便你实现「推荐标签」功能,只需要把 suggest字段标示为 true:

$tag = EstGroupe\Taggable\Model\Tag::where('slug', '=', 'blog')->first();$tag->suggest = true;$tag->save();

即可以用以下方法读取:

$suggestedTags = EstGroupe\Taggable\Model\Tag::suggested()->get();

重写 Util 类?

大部分的通用操作都发生在 Util 类,你想获取更多的定制权力,请创建自己的 Util 类,并注册服务提供者:

namespace My\Project\Providers;use EstGroupe\Taggable\Providers\TaggingServiceProvider as ServiceProvider;use EstGroupe\Taggable\Contracts\TaggingUtility;class TaggingServiceProvider extends ServiceProvider {    /**     * Register the service provider.     *     * @return void     */    public function register()    {        $this->app->singleton(TaggingUtility::class, function () {            return new MyNewUtilClass;        });    }}

然后在

注意 MyNewUtilClass必须实现 EstGroupe\Taggable\Contracts\TaggingUtility接口。

使用范例

$article = Article::with('tags')->first(); // eager load// 获取所有标签foreach($article->tags as $tag) {    echo $tag->name . ' with url slug of ' . $tag->slug;}// 打标签$article->tag('Gardening'); // attach the tag$article->tag('Gardening, Floral'); // attach the tag$article->tag(['Gardening', 'Floral']); // attach the tag$article->tag('Gardening', 'Floral'); // attach the tag// 批量通过 tag ids 打标签$article->tagWithTagIds([1,2,3]);// 去掉标签$article->untag('Cooking'); // remove Cooking tag$article->untag(); // remove all tags// 重打标签$article->retag(['Fruit', 'Fish']); // delete current tags and save new tags$article->retag('Fruit', 'Fish');$article->retag('Fruit, Fish');$tagged = $article->tagged; // return Collection of rows tagged to article$tags = $article->tags; // return Collection the actual tags (is slower than using tagged)// 获取绑定的标签名称数组$article->tagNames(); // get array of related tag names// 获取打了「任意」标签的 Article 对象Article::withAnyTag('Gardening, Cooking')->get(); // fetch articles with any tag listedArticle::withAnyTag(['Gardening','Cooking'])->get(); // different syntax, same result as aboveArticle::withAnyTag('Gardening','Cooking')->get(); // different syntax, same result as above// 获取打了「全包含」标签的 Article 对象Article::withAllTags('Gardening, Cooking')->get(); // only fetch articles with all the tagsArticle::withAllTags(['Gardening', 'Cooking'])->get();Article::withAllTags('Gardening', 'Cooking')->get();EstGroupe\Taggable\Model\Tag::where('count', '>', 2)->get(); // return all tags used more than twiceArticle::existingTags(); // return collection of all existing tags on any articles

如果你,即可使用以下标签读取功能:

// 通过 slug 获取标签Tag::byTagSlug('biao-qian-ming')->first();// 通过名字获取标签Tag::byTagName('标签名')->first();// 通过名字数组获取标签数组Tag::byTagNames(['标签名', '标签2', '标签3'])->first();// 通过 Tag ids 数组获取标签数组Tag::byTagIds([1,2,3])->first();// 通过名字数组获取 ID 数组$ids = Tag::idsByNames(['标签名', '标签2', '标签3'])->all();// [1,2,3]

标签事件

Taggabletrait 提供以下两个事件:

EstGroupe\Taggable\Events\TagAdded;EstGroupe\Taggable\Events\TagRemoved;

监听标签事件:

\Event::listen(EstGroupe\Taggable\Events\TagAdded::class, function($article){    \Log::debug($article->title . ' was tagged');});

单元测试

基本用例测试请见: tests/CommonUsageTest.php。

运行测试:

composer installvendor/bin/phpunit --verbose
