I am working on a project in Codeigniter 3.1.9 on PHP 8.2.12.
My question is I have a lot of dynamic data that gets brought into a static view to create multiple pages. The issue I have is that without creating my own PDF Library, or having every page identical, I would need to bring in different print style sheets for each page instance. I could bring in all the different stylesheets at once, so they all load every time a page loads, but that feels a bit clunky and unnecessary.
So, the solution I was hoping for is to have different stylesheets load in dynamically depending on which record is pulled in, with PHP. I already am doing this this with an admin check on the admin elements and styles which works beautifully. However, those instances are loading in stylesheets and elements that are fairly static from fixed views.
Here is the Recipe Controller:
<?php
class Recipe extends BaseController{
function __construct(){
parent::__construct();
// Loading in Pagination Library
$this->load->library('pagination');
// Loading in Recipe_model
$this->load->model('recipe_model');
$uri = $this->uri->uri_string();
$this->session->set_flashdata('uri', $uri);
}
function index(){
$recipe_linkname = $this->uri->rsegment(3);
if(!$recipe_linkname){
$recipe_linkname = $this->recipe_model->first_linkname();
}
$recipe = $this->recipe_model->read_record($recipe_linkname);
if(count($recipe) == 0){
show_404('');
die();
}
$data = array(
'title' => "Shirley's Recipes:".$recipe['name'],
'columns' => array('toc', 'recipe'),
'recipe' => $recipe,
'updated' => $this->format_date($recipe['updated'])
);
$this->load->view('templates/main', $data);
}
function flipbook(){
// Requires the user to be "logged in"
$this->require_login();
// Recipe Flipbook Pagination Configuration
$config['base_url'] = site_url('recipe/flipbook');
$config['total_rows'] = $this->recipe_model->num_rows();

Could I accomplish this with an IF statement and how would I set it up?
I tried setting the stylesheets to load individually, however with the if statement I wrote they both loaded anyway.
My if statement looked something like this:
<?php
if($recipe['linkname'] = 'gallonsizesweettea'){
echo '<link rel="stylesheet" type="text/css" href="/assets/css/public/page/print/recipes/printgallonsizesweettea.css" media="print" />';
}
if($recipe['linkname'] = 'applecobbler'){
echo '<link rel="stylesheet" type="text/css" href="/assets/css/public/page/print/recipes/printapplecobbler.css" media="print" />';
}
?>
What am I missing here? Thanks in advance for any help anyone could offer!
