thinkphp5.1有很方便的分页类,用render方法即可渲染分页的html代码
但"<<"的上一页和">>"这样的的下一页有时无法满足项目多变的需求,有必要自己定义分页的显示,比如
首页 上一页 1 2 3 ... 7 8 下一页 末页
这样,然而官方的手册并没有提到自定义分页样式的方法,我开始也只是简单的把分页的html替换成上一页下一页的文字
后来又搜到可以自己定义一个类来完成这个需求,首先需要在config目录创建paginate.php,文件内容
<?php return [ 'type'=>'app\index\pager\gcudPager'//自己的分页类可以随便放,只要命名空间写对 ];
然后复制"项目目录\thinkphp\library\think\paginator\driver\Bootstrap.php"到一个任意位置,改改命名空间,把paginate.php的type改成相应的命名空间,比如我就把文件复制到了"项目目录\application\index\pager\gcudPager.php",上面的type也是和这个路径对应的,然后把命名空间改成了"app\index\pager",对应的类名改成了gcudPager,这样就可以自行定义分页的形式了
首页的实现我是按照上一页来的,复制它的代码,略加修改
/**首页按钮
* @param string $text
* @return string
*/
protected function GetFirstButton($text='首页'){
if ($this->currentPage() <= 1) {
return $this->getDisabledTextWrapper($text);
}
$url = $this->url(1);
return $this->getPageLinkWrapper($url, $text);
}逻辑很简单,就是判断下当前页数,手动把页数变量设置为1,同理可以复制下一页的代码改成末页
/**末页按钮
* @param string $text
* @return string
*/
protected function GetLastButton($text='末页'){
if (!$this->hasMore) {
return $this->getDisabledTextWrapper($text);
}
$url = $this->url($this->lastPage());
return $this->getPageLinkWrapper($url, $text);
}其它上一页下一页也就是改个文本太简单不说,render函数部分需要把首页和末页按钮加进来
/**
* 渲染分页html
* @return mixed
*/
public function render()
{
if ($this->hasPages()) {
if ($this->simple) {
return sprintf(
'<ul class="pager">%s %s</ul>',
$this->getPreviousButton(),
$this->getNextButton()
);
} else {
return sprintf(
'<div class="page-captions">%s %s %s %s %s</div>',
$this->GetFirstButton(),
$this->getPreviousButton(),
$this->getLinks(),
$this->getNextButton(),
$this->GetLastButton()
);
}
}
}这样就弄完了,调用部分完全不用改,最后放上完整代码
