Add the array to the $data variable before passing it to the views

Question

Add the array to the $data variable before passing it to the views

Currently, I am using CI and I have a specific method to load a CSS file in the constructor for every main page (e.g. contents) like this:

$this->load->vars(array('add_css'=>array('contents')));

In my views, I check if the add_css array exists, and if it does, I load the contents.css file. However, in my controller file (specifically contents.php), there are numerous methods, all of which will always load the additional contents.css file. Some methods may also require their own separate CSS files. For instance, when on the review method, I want to load an additional rating.css file. Here is what I tried:

$data['add_css'] = array('rating');

Unfortunately, this approach doesn't work as the rating.css file overwrites the variables set in the constructor.

Is there a way for me to push the array instead? I attempted to use `array_push($data['add_css'],'rating')`, but it did not yield the desired results.

Thank you!

To achieve a more sophisticated solution, consider the following approach:
1. Start by adding a new protected property in your controller (or MY_Controller) to store all loaded CSS files.

protected $_addCss = array();

2. Create a method for adding new CSS files to this array:

protected function _addCssFile($file)
{
    $this->_addCss[] = $file;
    return $this; //Allows for chaining when adding files
}

3. Implement a method for manually loading all added CSS files.

protected function _loadCssFiles()
{
        //Load the variables and then reset the property to an empty array
    $this->load->vars(array('add_css' => $this->_addCss));
    $this->_addCss = array();
    return $this;
}

4. Utilize this functionality in your application controller as follows:

public function __construct()
{
        parent::__construct();
        $this->_addCssFile('contents');
}

public function test()
{
        //Chain the methods to add multiple CSS files
    $this->_addCssFile('contents')
        ->_addCssFile('rating')
        ->_loadCssFiles()
        ->load->view('test');
}

5. In your view:

echo '<pre>';
print_r($add_css);
echo '</pre>';

Result:
Array
(
    [0] => contents
    [1] => contents
    [2] => rating
)

Encountered a comparable issue. Review the contents of the array, transfer to a separate array, append fresh data to it, and replace the second array with the updated information.
