Question

I’am learning to make a blog in CodeIgniter 2.x . What I want – when user clicks on the link readmore on the blog’s page, it will redirect him to the page with corresponding id to show him a full article.

Now, while retrieving a $query->row(); from a database in content_model.php, i want to update a viewed column in database at the same time. So instead of showing him for example 34 views, it will show 35 views, and when someone open the same link it will shows him by one more – 36 views.

What’s the best way to do it without making it vulnerable to hackers somehow ?

Thank you in advance for any help.

When you retrieving data from database using CI framework, you check this following:

    if ($result_from_get_function->num_rows()>0){
    return   $this->updateViewColoumnByOne();
    }else{
    return false;
    }
    function updateViewColoumnByOne(){
    //retrieve number of view in view column, suppose 12.
    //plus one with it; 12+1=13
   //update it.
   //again retrieve the new update number of views
   //and return.
   }

I think this could help you.
