function create(){

if ($this- > input- > post(‘name’)){

$this- > MColors- > createColor();

$this- > session- > set_flashdata(‘message’,’Color created’);

redirect(‘admin/colors/index’,’refresh’);

}else{

$data[‘title’] = “Create Color”;

$data[‘main’] = ‘admin_colors_create’;

$this- > load- > vars($data);

$this- > load- > view(‘dashboard’);

}

}

Very similar things are in the edit() function. Notice the use of the $id argument to pull out the
appropriate color from the colors database.

function edit($id=0){

if ($this- > input- > post(‘name’)){

$this- > MColors- > updateColor();

$this- > session- > set_flashdata(‘message’,’Color updated’);

redirect(‘admin/colors/index’,’refresh’);

}else{

$data[‘title’] = “Edit Color”;

$data[‘main’] = ‘admin_colors_edit’;

$data[‘color’] = $this- > MColors- > getColor($id);

$this- > load- > vars($data);

$this- > load- > view(‘dashboard’);

}

}

Finally, here ’ s the delete() function. It also uses $id argument to act on the appropriate color ID.

function delete($id){

$this- > MColors- > deleteColor($id);

$this- > session- > set_flashdata(‘message’,’Color deleted’);

redirect(‘admin/colors/index’,’refresh’);

}

}//end class

Now it ’ s time to create your MColors model functions. You ’ re going to need getColor() ,
getAllColors() , createColor() , updateColor() , and deleteColor(). Because you ’ ve built
similar functions in all of your models so far, they ’ re shown on the next page without extraneous context.

For a good refresher on how such functions are built, see the section on “ Creating the Category

Management Tools ” in Chapter 6.
