Chapter 6: Creating a Dashboard

If no POST data are detected, show the form, but along the way, gather up all subcategories eligible for
product assignment with an MCats model function named
getCategoriesDropDown()
. You ' ll build
this function and the other function you need in a minute. First, here ' s the
create()
function for your
controller.
function create(){
if ($this-
>
input-
>
post(`name')){
$this-
>
MProducts-
>
addProduct();
$this-
>
session-
>
set_flashdata(`message','Product created');
redirect(`admin/products/index','refresh');
}else{
$data[`title'] = "Create Product";
$data[`main'] = `admin_product_create';
$data[`categories'] = $this-
>
MCats-
>
getCategoriesDropDown();
$this-
>
load-
>
vars($data);
$this-
>
load-
>
view(`dashboard');
}
}
The
addProduct()
function in the MProducts model is a little more complicated than the
addCategory()
function you created in the last section, and for one good reason: You have to upload an
image and a thumbnail.
The first part of the function is extremely straightforward, as you are expecting a series of POST fields
from a form, fields like: name, shortdesc, and so on. These are extremely easy to gather and populate a
data array with:
function addProduct(){
$data = array(
`name' =
>
$_POST[`name'],
`shortdesc' =
>
$_POST[`shortdesc'],
`longdesc' =
>
$_POST[`longdesc'],
`status' =
>
$_POST[`status'],
`grouping' =
>
$_POST[`grouping'],
`category_id' =
>
$_POST[`category_id'],
`featured' =
>
$_POST[`featured'],
`price' =
>
$_POST[`price']
);
Next, to enable file uploads, you need to do a bit of configuration work. Using a
$config
array, set
values for upload_path (where you expect images to be stored), allowed_types (to restrict the types of
files that can be uploaded), max_size, and so on, and then load the upload library.
files that can be uploaded), max_size, and so on, and then load the upload library.
Please note that you must set the upload_path folder to be writable for any of this to work! Checking on
that and making sure it is writable will save you a lot of time.
