> TP6.0 默认提供的分页代码中css样式类名是Bootstrap3中的，如果项目中使用的是Bootstrap4，则不能正确展示分页样式效果，需要修改分页驱动，使其样式正确显示 #### 1. TP6.0 默认分页 --- **默认分页驱动类文件** ``` vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php ``` **默认分页代码** ```html <ul class="pagination"> <li><a href="?page=1">«</a></li> <li><a href="?page=1">1</a></li> <li class="active"><span>2</span></li> <li class="disabled"><span>»</span></li> </ul> ``` #### 2. 修改默认分页驱动 --- **a. 复制默认分页驱动类** ``` vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php ``` **b. 粘贴到 `app/driver` 目录下，重命名为 MyPage、修改命名空间** ``` app/driver/MyPage.php ``` **c. 修改文件 `app/provider.php`，添加以下内容** ``` // 修改默认分页驱动 'think\Paginator' => app\driver\MyPage::class, ``` **d. 修改自定义分页驱动文件 `app/driver/MyPage.php`** 给 li 添加 .page-item，给 a 标签 和 span 标签添加 .page-link **e. 修改前和修改后的对比**   **f. 修改后的分页驱动，在 Bootstrap4.x 中可直接使用** ```php <?php namespace app\driver; use think\Paginator; /** * Bootstrap 分页驱动 */ class MyPage extends Paginator { /** * 上一页按钮 * @param string $text * @return string */ protected function getPreviousButton(string $text = "«"): string { if ($this->currentPage() <= 1) { return $this->getDisabledTextWrapper($text); } $url = $this->url( $this->currentPage() - 1 ); return $this->getPageLinkWrapper($url, $text); } /** * 下一页按钮 * @param string $text * @return string */ protected function getNextButton(string $text = '»'): string { if (!$this->hasMore) { return $this->getDisabledTextWrapper($text); } $url = $this->url($this->currentPage() + 1); return $this->getPageLinkWrapper($url, $text); } /** * 页码按钮 * @return string */ protected function getLinks(): string { if ($this->simple) { return ''; } $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['first'] = $this->getUrlRange(1, 2); $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); $block['last'] = $this->getUrlRange($this->lastPage - 1, $this->lastPage); } $html = ''; if (is_array($block['first'])) { $html .= $this->getUrlLinks($block['first']); } if (is_array($block['slider'])) { $html .= $this->getDots(); $html .= $this->getUrlLinks($block['slider']); } if (is_array($block['last'])) { $html .= $this->getDots(); $html .= $this->getUrlLinks($block['last']); } return $html; } /** * 渲染分页html * @return mixed */ public function render() { if ($this->hasPages()) { if ($this->simple) { return sprintf( '<ul class="pager">%s %s</ul>', $this->getPreviousButton(), $this->getNextButton() ); } else { return sprintf( '<ul class="pagination">%s %s %s</ul>', $this->getPreviousButton(), $this->getLinks(), $this->getNextButton() ); } } } /** * 生成一个可点击的按钮 * * @param string $url * @param string $page * @return string */ protected function getAvailablePageWrapper(string $url, string $page): string { return '<li class="page-item"><a href="' . htmlentities($url) .
