This is a multi part question.
Background:
I’m building my first site using CakePHP, and I like it so far. I’ve got a DB setup, initial data loaded, and a few models, views, and controllers to interface with the data.
I’ve created a globally accessible function to create Add/Edit/Delete type image links in various areas. It will be used across multiple views, so I need it accessible, essentially, everywhere. The function is defined in /app/config/bootstrap.php. I was hoping to use the HTML Helper’s $html->image() and $html->link() methods to facilitate this, but they’re not available in bootstrap.php and I’m not sure how to load/access the HTML Helper where I’ve defined my function.
Questions:
1) Is this a reasonable/idiomatic place to define a function of this sort?
2) If this isn’t the correct place to define the function, where should I define it?
3) If this is the correct place to define the function, how can I go about loading various CakePHP helpers?
Again, I am new to CakePHP, so please let me know if my question is unclear, and forgive my ignorance. I’ve read/searched through a fair amount of the CakePHP documentation and while I can find plenty of references to loading helpers within Controllers via App::import(...); or $helpers = array(...);, I do not seem to have access to the App object and the $helpers member is specific to the AppController class, I assume. I assume I’m going about this incorrectly, so please help me understand the Cake way of accomplishing this.
No, that is not the correct place for such a function (or more accurately, it goes against the MVC paradigm). A better approach would be to create your own helper for the function. Depending on the complexity of the links you could also use elements.
As a rule of thumb only functions that are completely independent of anything else in the app should be in bootstrap.php, and even most of those would often be better somewhere else.
