TP5中的分页样式(详细)

时间:2022-10-27 14:21:46

最近和tp5又打上交到了,前段时间使用它写接口,因此没有探究tp5和前端的联系及其便捷之处。最近做的项目前端后台联系较为紧密,因此将几个常用的点分享记录一下!

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。具体看官方文档,很简单易懂,这里不再说用处,下一篇我会将搜索+分页具体实例写出来供参考。

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>";
}

/**
* 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['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;
}

/**

* @return mixed
*/

public function render()
{

if ($this->hasPages()) {
if ($this->simple) {
return sprintf(
'%s<div class="pagination">%s %s %s</div>',
$this->css(),
$this->prev(),
$this->getLinks(),
$this->next()

} else {
return sprintf(

return ' <style type="text/css">

}
.pagination a:hover{

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,
],

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。
