Codeigniter路由器$ this-> uri-> segment无法正常工作

Question

I have two-way access:

1 : http://website.com/main/selectBaivietTag/video/chon-loc/2 //$this->uri->segment(5)=2
2 : http://website.com/video/tag/chon-loc/2 //$this->uri->segment(5)=1

And my router

$route['([a-z\-]+)/tag/([a-z\-]+)/(:num)']='main/selectBaivietTag/$1/$2';
$route['([a-z\-]+)/tag/([a-z\-]+)']='main/selectBaivietTag/$1/$2';

I want access the second but $this->uri->segment(5)=2 not =1, Please help me! Thanks alot!

Answer 1

try use

for the first link

1 : http://website.com/main/selectBaivietTag/video/chon-loc/2

you can get your value with this

$this->uri->segment(5)

this will give your value ie 2 but for second links

2 : http://website.com/video/tag/chon-loc/2

you can get your value with this

$this->uri->segment(4) 

this will give your value ie 2

Answer 2

try use

$this->uri->rsegment(5); :))

Answer 3

Try following code:

<?php 
      $segment = $this->uri->segment_array(); 
      echo $segment['5']; 
?>

Working fine for me.
