• With that much code, could you add a description of what the code is doing ? It could help to know at first glance what your code is about. – Marc-Andre Mar 24 '14 at 18:50

• Please turn on notices and warnings (error_reporting(-1)), you're calling non-static methods statically all over the place. Don't. Also, if you want code to be reviewed, please follow the (coding-style conventions)[php-fig.org] your framework subscribes to. It makes the reviewer's life easier not having to get accustomed to your indentation-style. Oh, and 10,000 records is all fine and dandy, but I'd test my code up to 10,000,000 records before making any assumptions as far as performance goes. I'd also use apache benchmark (ab -c 100 -n 10000) – Elias Van Ootegem Mar 26 '14 at 14:26

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.

• not only is the first point arguably bad advice, you also switched two lines so that you return before you can set $this->msg. – amon Mar 24 '14 at 22:25 • you say arguably, do you mean that some would say it is bad where some would say it is good? or would everyone have mixed feelings? @amon – Malachi Mar 24 '14 at 22:45 • Why break them up into seperate functions? Because of the re-use of some of them? – Kevin Mar 25 '14 at 12:01 • @o7thWebDesign, yes. I noticed that you use them over and over again. it kind of looks like you weren't sure how to structure the functions. like whether to put action stuff together or the components together. you can actually put the components together first, in a function, and then create the functions the way you have them with the other functions being called inside of them. it will make all of them look a lot cleaner, and probably reduce some of the code. – Malachi Mar 25 '14 at 12:35 • @Malachi talking about the if then statements in the functions not sure what you mean about the paragraph under this. – Kevin Mar 25 '14 at 14:36 By using a framework like CodeIgniter, which has a database abstraction layer, your application will benefit from model-view-controller separation and avoid SQL injection bugs. That automatically makes your application better than the average PHP code. That's a good start. I'll lead with a trivial observation first. In PHP library code, such as this file, omit the trailing ?>. Why? It's allowable to have the opening <?php tag unmatched. It is easy to end up with a Carriage return and/or Newline at the end of the file, which the PHP interpreter will immediately print as output, since it's a templating language. Once the HTTP body starts, any subsequent code will not be able to manipulate HTTP headers: you can't issue cookies, set cache control headers, or set the HTTP status code without getting an error. The heart of your code appears to be prepArgs($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.

• thank you for all this. I had already refactored most of it taking the commons out and into its own private helper. Im not real concerned with naming conventions ;) this wuld b alot differner in c# ;) for the most part the paging is in there for the limits on the queries. and the point of this is to prevent havin to type \$this->db stuff fo every single model i may need to write out :) – Kevin Mar 30 '14 at 12:16
