tp5 分页详解
最常用的应该就是分页了，tp5已经将分页给封装好了，实在是方便！
分页主要在model中查询语句例使用paginate()函数。
tp5分页的默认样式很丑，或者说根本没有样式。
以下为修改方法（参考其他大神的扩展代码）：
1.首先在tp的扩展文件夹extend中创建page文件夹（文件夹名称可以自己决定，命名空间对就行）
2. 将自定义分页类文件page.php放到page文件夹下
<?php
namespace page;
use think\Paginator;
class Page extends Paginator
{
//首页
protected function home() {
if ($this->currentPage() > 1) {
return "<a href='" . $this->url(1) . "' title='首页'>首页</a>";
} else {
return "<p>首页</p>";
}
}
//上一页
protected function prev() {
if ($this->currentPage() > 1) {
return "<a href='" . $this->url($this->currentPage - 1) . "' title='上一页'>上一页</a>";
} else {
return "<p>上一页</p>";
}
}
//下一页
protected function next() {
if ($this->hasMore) {
return "<a href='" . $this->url($this->currentPage + 1) . "' title='下一页'>下一页</a>";
} else {
return"<p>下一页</p>";
}
}
//尾页
protected function last() {
if ($this->hasMore) {
return "<a href='" . $this->url($this->lastPage) . "' title='尾页'>尾页</a>";
} else {
return "<p>尾页</p>";
}
}
//统计信息
protected function info(){
return "<p class='pageRemark'>共<b>" . $this->lastPage .
"</b>页<b>" . $this->total . "</b>条数据</p>";
}
/**

* @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['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;
}

public function render()

color:#808080;
}
.dates li {font-size: 14px;margin:20px 0}
.dates li span{float:right}
</style>';
}
}
3.修改配置文件（/application/config.php）
//分页配置
'paginate' => [
'type' => 'bootstrap',
'var_page' => 'page',
'list_rows' => 15,
],
将上面分页配置改为：
//自定义分页配置
'paginate' => [
'type' => 'page\page',//分页类
'var_page' => 'page',
'list_rows' => 15,
],
效果图：
看下样式要好很多，想要自己写类文件也可以按照这种方法来做。
