I really like the Aldehyde theme when it updated and it’s standard blog view. Trouble is I couldn’t easily customise it via the GUI so I guess I’ll have to dive into the code.
After initial search it seemed prudent to create a child theme so any serious customisations don’t get lost after an update.
I have to say at the moment I have no idea where changes to a theme are kept when changing it via the GUI.
As I run my own server I can do a lot of the changes via a SSH session.
I create a new child theme directory in the /var/www/wp-content/themes/ directory and fill out the style.css file with:
/* Theme Name: My Child Theme Theme URI: http: //none.com/ Description: This is a custom child theme I have created. Author: nullgenome Author URI: http: //rejected.io/ Template: aldehyde Version: 0.1 */ @import url("../aldehyde/style.css");
As the link above explains, the Template part references the parent theme and the “@” line references the parent’s main style file, otherwise the child would show nothing when it’s activated.
What’s the reason why I wanted a child theme for customisations? Well the standard grid view comes with a small picture with the post entry that by default is blank. What’d be nice is to have a set picture relating to the subject of the post.
So as a test and following the following post I copy the source file:
I then download a NetApp corporate image from here and upload it via the WordPress uploading tool. The file then is place in the /var/www/wp-content/uploads/2015/06/ directory (I guess I could use SCP or something but CBA) and I then update the following line in the content-grid file from:
<a href="<?php the_permalink() ?>" title="<?php the_title() ?>"><img src="<?php echo get_template_directory_uri()."/assets/images/placeholder2.jpg"; ?>"></a>
<a href="<?php the_permalink() ?>" title="<?php the_title() ?>"><img src="<?php echo get_template_directory_uri()."/../../uploads/2015/06/netapp.png"; ?>"></a>
This then successfully updates the image of all my post entries to the uploaded NetApp image.
Now how do I customise it based on post subject? (update to follow)….
It seems I didn’t need to do any of this and just use the Featured Image setting in each post, which I’ve pretty much done.
