2 questions: error404 handling and regular expressions in db..

[eluser]Ji31[/eluser]
Hi,

I have two questions, so I put them here together:

1.) If I have a path like this: http://mysite.com/id/20
And if I enter some nonexistent id (for example http://mysite.com/id/160) I get a php error. What can I do to get the error404 page?

2.) I have in the db the column named keywords where I have saved keywords separated by space. And if I want to show all articles with this keyword, how do I pass the regular expression to $this->load->where('');? Or how do I should select them?


Thanks a lot

1. First do some error checking on the id's - if they are non-existant use show_404('page'); You can read about this in the Error Reporting documentation.

2. You could use the like() method. Active Record documentation.

Code:

$this->db->like('keywords', ' ' . $query . ' ');

I included the spacing on the query so your matching exact terms. 'put' will only find 'put' and not 'putting'
