thinkPHP5.1框架使用SemanticUI实现分页功能示例

本文实例讲述了thinkphp5.1框架使用semanticui实现分页功能。分享给大家供大家参考，具体如下：

1、config目录下新建paginate.php，下面是文件的内容

<?php
//分页配置
return
  [
    'type' => 'semantic',
    'var_page' => 'page',
  ];

2、thinkphp\library\think\paginator\driver\下新建semantic.php，下面是文件的内容

<?php
/**
 * created by alic(alicfeng) on 17-6-15 下午9:17 from phpstorm.
 * email is [e-mail]
 */
namespace think\paginator\driver;
use think\paginator;
class semantic extends paginator
{
  private static $previousbuttonhtml = '<i class="icon left arrow"></i>';
  private static $nextbuttonhtml = '<i class="icon right arrow"></i>';

   * 上一页按钮
   * @return string
   */
  protected function getpreviousbutton() {
    if ($this->currentpage() <= 1) {
      return $this->getdisabledtextwrapper(semantic::$previousbuttonhtml);
    }
    $url = $this->url(
      $this->currentpage() - 1
    );
    return $this->getpagelinkwrapper($url, semantic::$previousbuttonhtml);
  }
  /**
   * 下一页按钮
   * @return string
   */
  protected function getnextbutton() {
    if (!$this->hasmore) {
      return $this->getdisabledtextwrapper(semantic::$nextbuttonhtml);
    }
    $url = $this->url($this->currentpage() + 1);
    return $this->getpagelinkwrapper($url, semantic::$nextbuttonhtml);
  }

    ];

    } elseif ($this->currentpage <= $window) {

  }
}

3、搞定
