||
| 10 | * Class Html |
||
| 11 | * |
||
| 12 | * Content should be either a rendered HTML string or an object that when cast to string renders the HTML. |
||
| 13 | * Also a slim templateing system is provided. You can use this by sending an array as content, but the |
||
| 14 | * array must follow some strict rules. The first value (no key), should be the template string. Any key/value |
||
| 15 | * pair added to this array will be applied as replacements in the template in the following manner: |
||
| 16 | * |
||
| 17 | * - The content key must be a unique string name, like `city` |
||
| 18 | * - The place in the template must be prefixed with `{:` and end with `}`, i.e. `{:city} |
||
| 19 | * |
||
| 20 | * Example: |
||
| 21 | * |
||
| 22 | * ```php |
||
| 23 | * Router::add('|city/(?<city>\w+)|', function(Request $request): Html { |
||
| 24 | * $template = <<<TEM |
||
| 25 | * <html> |
||
| 26 | * <head> |
||
| 27 | * <title>{:name}</title> |
||
| 28 | * </head> |
||
| 29 | * <body> |
||
| 30 | * <h1>City {:name}</h1> |
||
| 31 | * <p>On {:street}</p> |
||
| 32 | * </body> |
||
| 33 | * </html> |
||
| 34 | * TEM; |
||
| 35 | * |
||
| 36 | * $data = [ |
||
| 37 | * $template, |
||
| 38 | * 'name' => $r->param('city'), |
||
| 39 | * 'street' => 'Mainstreet', |
||
| 40 | * ]; |
||
| 41 | * return new Html($data, 200); |
||
| 42 | * |
||
| 43 | * } |
||
| 44 | * ``` |
||
| 45 | * |
||
| 46 | * Going to localhost/city/Oslo, will render as: |
||
| 47 | * |
||
| 48 | * ``` |
||
| 49 | * <html> |
||
| 50 | * <head> |
||
| 51 | * <title>Oslo</title> |
