I had heard of APIs before taking this class, but this week’s readings and videos did a good job of breaking down this complex topic. The kitchen analogy used in the “What is an API?” video was helpful in terms of understanding how an API works as a messenger that communicates user requests and delivers responses back to the user. I recently booked a flight using the online travel service Kayak, and did not think about the fact that Kayak was using airline APIs to find me flights based on the parameters I defined. Kayak accesses the airline APIs and aggregates information from them based on user requests.
I also tried out one of the examples provided in the video about REST APIs. I typed the sample URL into my search bar and tweaked it for my hometown of Mendon, Massachusetts, which resulted in a page written in JSON that allowed me to access the GPS coordinates for my hometown (latitude: 42.1056525, longitude: -71.5522859). I then went to the main Google Maps site and entered these coordinates, and was taken directly to the center of my hometown on the map. I will have to do a bit more research on the topic of APIs in order to more fully understand how the concepts can be applied to WordPress. I imagine that APIs are probably used in a lot of plugins that access data from outside websites, such as those that pull in data from Twitter or Instagram feeds.
I spent this weekend working on the modifications for my WordPress site. As I mentioned in last week’s blog post, I was able to create my child theme and activate it on my local site, but I still have to play around with the fonts and colors of the site. I plan to do that towards the end of my project, once all of my other modifications are complete. One specific question I had regarding editing the styles.css file for my child theme is, how do you edit the fonts if your parent theme uses the Font Awesome toolkit? For example, I tried changing the font for my site header, but it is not working, and I’m thinking it’s due to the fact that my parent theme uses Font Awesome and thus has multiple CSS files. How do I change the fonts in this case?
I also decided to tackle the custom post type modification by building a custom post type plugin. I was able to write the code for this plugin using these instructions, but ran into a lot of issues on the way to getting it to work. For example, when I tried to activate the plugin from my wp-admin panel on my local site, I kept getting the following error:
Parse error: syntax error, unexpected ” => array(‘ (T_CONSTANT_ENCAPSED_STRING), expecting ‘)’ in /Applications/MAMP/htdocs/finalproject/wp-content/plugins/therunningglover-run-post-plugin/therunningglover-run-post-plugin.php on line 18
I could not for the life of me figure out what the issue on line 18 was, and so back to Google I went. Luckily, the Stack Overflow gods were there to help out, and I figured out that I had forgotten a single quote (‘) on line 18 of my plugin code. I fixed the issue, refreshed the page, and the plugin was activated. However, the custom post type was still not appearing in my admin panel, and so I decided to go back to square one and rewrite my code using the steps listed on the WordPress codex. I got it to work within five minutes. Lesson learned — use the WordPress codex first. I now have a custom post type on my left admin panel called “Run.” Now I’m working on adding a custom metabox called “Run Details” with metadata (custom fields). One question I have is, how do I get my custom post type posts to show up on the home page of my site, rather than just under the Blog page?
This coming week, I want to download a plugin for Strava and see how I can use it to pull in information about my most recent running routes onto the sidebar of my site. When modifying the code of an existing plugin, do we need to create a “child plugin” (if that is such a thing)? I will also attempt to build a lightbox slideshow to display some of my photographs, but may end up using a plugin for this. I’m also planning to load some of my files using the FTP client later this week, to ensure everything is working correctly on my hosted site. I’m feeling a bit overwhelmed at all that I have to do in the next week-and-a-half, and am hoping that I can at least get three quarters of my proposed modifications done before the final project deadline.
Regarding GitHub, should I only be syncing files that I’m coding myself? For example, the plugins that I downloaded and added to my page from WP also synced to my final project GitHub repo. Should I remove the code for these plugins from my final project repo since these are not something I coded myself? If so, what is the best way to do this?
