CodeIgniter Model I built

Question

Can I get some pointers, critiques and/or comments on the following model? (p.s. performance seems great... tested all methods up to 10,000 records)

Answer 1

This Function can be shorter.

public function qdelete(){
    $tbl = self::prepArgs(4, func_get_args());
    $this->db->delete('Storage_Users');
    if($this->db->affected_rows() > 0){
        return TRUE;
    }else{
        $this->msg = 'There was an issue removing that record.<br />' . $this->db->_error_message();
        return FALSE;
    }
}

If you write it like this

public function qdelete(){
    $tbl = self::prepArgs(4, func_get_args());
    $this->db->delete('Storage_Users');
    if($this->db->affected_rows() <= 0){
        $this->msg = 'There was an issue removing that record.<br />' . $this->db->_error_message();
        return FALSE;
    }
    return TRUE;
}

this probably just seems like a code golf, but this is really straight to the point, and doesn't clutter your code with else statements.

This little bit of Code has some extra's in it that you don't need as well.

    if($valid){
        $this->db->update($tname, $data);
        $a = ($this->db->affected_rows() > 0);
        if(!$a){
            $this->$msg .= $this->db->_error_message();
            return FALSE;
        }else{
            return TRUE;
        }
    }else{
        return $valid;  
    }

When you enter the outside if statement, it's valid then you have the nested if statement. if !$a then it will return a message otherwise it is true. you could just write it like this

    if($valid){
        $this->db->update($tname, $data);
        if(!($this->db->affected_rows() > 0)){
            $this->$msg .= $this->db->_error_message();
            return FALSE;
        }
        return TRUE;
    } else {
        return $valid;
    }

this way you don't have to declare an extra variable, the variable isn't used for anything else here and just uses resources in being declared.

Function SetupEdits

ugh!

what is $w? Why is $w unset inside the if statement, the scope should destroy it when focus leaves the if statement. if you did need to unset these variables then you should unset the others as well $wCt

It really looks to me like you need to break these if statements into separate functions, that function is just too big and ugly looking.

talking about the if then statements in the functions

I noticed that you use them over and over again. it kind of looks like you weren't sure how to structure the functions. like whether to put action stuff together or the components together. you can actually put the components together first, in a function, and then create the functions the way you have them with the other functions being called inside of them. it will make all of them look a lot cleaner, and probably reduce some of the code.

Answer 2

By using a framework like CodeIgniter, which has a database abstraction layer, your application will benefit from model-view-controller separation and avoid SQL injection bugs. That automatically makes your application better than the average PHP code. That's a good start.

---

I'll lead with a trivial observation first. In PHP library code, such as this file, omit the trailing ?>. Why? It's allowable to have the opening <?php tag unmatched. It is easy to end up with a Carriage return and/or Newline at the end of the file, which the PHP interpreter will immediately print as output, since it's a templating language. Once the HTTP body starts, any subsequent code will not be able to manipulate HTTP headers: you can't issue cookies, set cache control headers, or set the HTTP status code without getting an error.

The heart of your code appears to be prepArgs($which, $args), which in turn calls setupSelect($args), setupInsert($args), setupEdit($args), or setupDelete($args) based on the value of $which. The use of 1/2/3/4 for $which had me initially puzzled: why does qdetails() need to prep 1 argument, while qinsert() needs 2 arguments, and qedit() needs 3? Instead of magic numbers, please define() some constants.

The choice of the name setupEdit() is odd. SELECT, INSERT, and DELETE are all SQL commands; EDIT is not. I could understand if you consistently used "application-layer" terminology such as "list", "add", "delete", and "edit". However, given the names of the existing three other functions, it should just be setupUpdate().

The behaviour of prepArgs(1, …) and prepArgs(4, …) is inconsistent with prepArgs(2, …) and prepArgs(3, …). With 1 and 4, it really just prepares the arguments, but does not call $this->db->get() or $this->db->delete(). With 2 and 3, it actually does call $this->db->insert() and $this->db->update(). That seems like a source of confusion and eventual bugs.

The paginator() member and $this->pagination seem to be independent of everything else in the class. I think that paginating is a responsibility of the controller, not the model. The $config that you build in the paginator() method is definitely presentation-layer code, not database-layer code.

---

What has me most concerned is that the bulk of setupSelect(), setupEdit(), and setupDelete() are identical repeated code. At a minimum, the common clauses 'where', 'or_where', 'where_in', 'or_where_in', 'where_not_in', 'or_where_not_in', 'like', 'or_like', 'not_like', 'or_not_like', 'group_by', 'having', 'or_having', and 'join' should be in a private helper function that all of them call.

Even after factoring out the common code into a helper function, it's still a lot of almost-repeated code! Unfortunately, PHP does not let you call member methods of $this->db dynamically using reflection, so it probably can't be reduced much further.

At this point, I have to ask: what do you gain for these 760 lines of code (including blank lines and comments)? Mostly, it seems to provide an alternate syntax for expressing your SQL clauses as arrays rather than sequential method calls. Perhaps you need that for your application, but at first glance, I'm skeptical of the cost-benefit balance.
