PHP Pagination - buttons?

Hi,
I'm struggling with working pagination in PHP. According to the documentation, I can use those links to go to the next page of the collected results. I can put out a certain amount of results per page, which I want, but I also want to go from page to page - I want to have working "Next", "Previous", "First" and "Last" buttons too.

But, in PHP, I have tried to write the exact equivalents of those, and it doesn't work. See my code:

'Next'

This, unfortunately, don't work. Frankly I don't know what does.

I have seen other threads on this matter, but they have all focused on Python or other languages, so none of them help me. The ones I am working with are PHP foremost, with some Laravel, HTML and Blade.

Any advice? Every bit of help is greatly appreciated

What is the response link header code for rel="next" look like after your PHP code makes the request against the API? It should give you the next page like ?page=2&per_page=3 instead of ?page=1&per_page=3

While I don't have anything to share (I'm not a developer and I don't know PHP)...but I saw that your href link had the word "infrastructure" rather than "instructure". Many Canvas schools have URLs with the word "instructure" in their URLs, so I wanted to point this out. I have no idea if this will help at all in your case. Just adding my $0.02.

@sam_ofloinn ,

This looks like you're confusing API calls with web links within the browser.

All of your descriptions and narrative make it sound like you're talking about making an API call, but you don't have /api/v1/ in the URL. What you do have is part of a regular anchor element's href attribute. That means that if someone clicked on it, it should open it up in a browser. API calls should not open directly in a browser, but they should be consumed by some program that knows how to interpret JSON results.

JEFHQ12951 is talking about the response header and the links returned with an API call and you're talking about links on buttons, which the API doesn't have.

Since you're running in PHP and talking about buttons, are you using an LTI? If so, then any internal links are up to you to handle pagination if needed. If you're trying to call content from within Canvas from your LTI, then the routing is set up incorrectly. Since Canvas doesn't understand it, it just keeps returning the same thing.
