這篇文章主要介紹了thinkPHP5.1框架使用SemanticUI實(shí)現(xiàn)分頁(yè)功能,結(jié)合實(shí)例形式分析了SemanticUI擴(kuò)展插件的定義及使用分頁(yè)相關(guān)操作技巧,需要的朋友可以參考下

本文實(shí)例講述了thinkPHP5.1框架使用SemanticUI實(shí)現(xiàn)分頁(yè)功能。分享給大家供大家參考，具體如下：

1、config目錄下新建paginate.php，下面是文件的內(nèi)容

<?php
//分頁(yè)配置
return
  [
    'type' => 'Semantic',
    'var_page' => 'page',
  ];

2、thinkphp\library\think\paginator\driver\下新建Semantic.php，下面是文件的內(nèi)容

<?php
/**

 */
namespace think\paginator\driver;
use think\Paginator;

{
  private static $previousButtonHtml = '<i class="icon left arrow"></i>';
  private static $nextButtonHtml = '<i class="icon right arrow"></i>';
  /**
   * 上一頁(yè)按鈕
   * @return string
   */
  protected function getPreviousButton() {
    if ($this->currentPage() <= 1) {
      return $this->getDisabledTextWrapper(Semantic::$previousButtonHtml);
    }
    $url = $this->url(
      $this->currentPage() - 1
    );
    return $this->getPageLinkWrapper($url, Semantic::$previousButtonHtml);
  }
  /**
   * 下一頁(yè)按鈕
   * @return string
   */
  protected function getNextButton() {
    if (!$this->hasMore) {
      return $this->getDisabledTextWrapper(Semantic::$nextButtonHtml);
    }
    $url = $this->url($this->currentPage() + 1);
    return $this->getPageLinkWrapper($url, Semantic::$nextButtonHtml);
  }
  /**
   * 頁(yè)碼按鈕
   * @return string
   */
  protected function getLinks() {
    $block = [
      'first' => null,

    ];
    $side  = 3;
    $window = $side * 2;

      $block['first'] = $this->getUrlRange(1, $this->lastPage);
    } elseif ($this->currentPage <= $window) {
      $block['first'] = $this->getUrlRange(1, $window + 2);
      $block['last'] = $this->getUrlRange($this->lastPage - 1, $this->lastPage);
    } elseif ($this->currentPage > ($this->lastPage - $window)) {
