thinkPHP5.1框架使用SemanticUI实现分页功能示例

唐伯虎

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
/**

 * Email is alic@samego.com
 */
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);
  }
  /**
   * 页码按钮
   * @return string
   */
  protected function getLinks() {
  $block = [
    'first' => null,
    'slider' => null,
    'last'  => null
  ];
  $side  = 3;
  $window = $side * 2;
  if ($this->lastPage < $window + 6) {
    $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)) {

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

3、搞定
希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
