Codeigniter uri->segment doesn't work in query

Question

I'm passing some variables through the uri, I then collect them using $this->uri->segment(3) make an active record query using the value i collect. when one of the variable is a composed word such as "first_last" the query returns null even if i know the DB has such entry. If however it is a single word such as "first" the query works fine. Thank you for your help

Answer 1

I think it's because of the denied chars in the URL. See the config of CI and add "_" in the allowed char's regexp

Answer 2

将“ first_last”更改为“ first-last”也会导致下划线对网址的影响不佳，然后查看其是否有效;）
