Codeigniter 3.1.0和引导分页链接
在我的codeigniter分页链接上,我使用的是bootstrap 3+Codeigniter 3.1.0和引导分页链接,codeigniter,Codeigniter,在我的codeigniter分页链接上,我使用的是bootstrap 3+ 当我在第一个链接上时,它隐藏了哦,您必须修改分页类的create_链接。我要做的是用MY_Pagination.php扩展system/libraries/Pagination.php类,这样您就可以重写该行为,并根据您的偏好对其进行相应的修改 顺便说一句,检查一下课程,我想你应该看看第563行: // Render the "First" link. if ($this->first_link !

您必须注意if条件才能始终呈现链接。那么,您必须修改分页类的create_链接。我要做的是用MY_Pagination.php扩展system/libraries/Pagination.php类,这样您就可以重写该行为,并根据您的偏好对其进行相应的修改 顺便说一句,检查一下课程,我想你应该看看第563行:

要始终呈现链接,您必须注意if条件。我刚刚以稍微不同的方式覆盖了核心库的create_链接,以实现这一点。因此,您所要做的就是在application/libraries中创建一个文件名My_Pagination.php,并将此代码放在其中,该代码是从core library Pagination.php的create_link方法复制的
