Entry approval is a Gravity View feature I use often. Even if I’m not using Gravity View on a project that needs to filter out some entries, I’ll save the same data in the $wpdb->_gf_entry_meta table to be compatible. The meta key is_approved contains one of the values in the table below. Icon Value Definition… Continue reading Gravity View is_approved enumeration

I replicated wordpress.org’s code reference system for my own project. WordPress provides a template tag get_the_title() and it’s documented at https://developer.wordpress.org/reference/functions/get_the_title/. A plugin I just launched provides a template tag invp_get_the_price() and it’s documented at https://inventorypresser.com/docs/reference/functions/invp_get_the_price/ I learned that the page content is generated by scanning a plugin folder and extracting PHPDoc comments from the… Continue reading Mimic the WordPress.org developer reference for your project

I built a WordPress plugin that saves a copy of all Gravity Forms entries in a Google Sheet as they are received. Entries to Google Sheet is the glue between a Gravity Form and a Google Sheet. https://entriestogooglesheet.com

This is confusing: calls to get_fields() find no Advanced Custom Fields values saved with a specific post, but calls to get_field() find values for the same post. This happens when ACF did not insert the field values, and the secondary value with the meta_key beginning with an underscore does not exist. The post has the… Continue reading ACF get_fields() not working but get_field() does

I have written and released a bash script that extracts WordPress websites and updates their local copies in my computer. It’s called exfil, it’s free and open-source, and lives on Github at https://github.com/csalzano/exfil/. To celebrate it’s release, I demoed exfil at the August 2020 burbswp.com virtual meetup, “What I’ve Learned Since Lockdowns Started”. I plan… Continue reading Extract WordPress databases and files with exfil

Out of the box, The Events Calendar plugin for WordPress is amazing and a pleasure to work with as a developer. However, it does not show users Media Library uploads that are attached to event posts. I made a plugin to bring this functionality to the Single Event view, it’s free and open-source, and you… Continue reading Show Attachments on The Events Calendar

As of this writing, it is not possible to delete a meta value using the WordPress REST API. Post meta updates must be communicated while inserting and updating post objects, and the only way to “remove” meta fields is to write blank values over their current values. I wrote a free and open-source plugin to… Continue reading How to Delete Meta Fields with the WordPress REST API

The WordPress block editor uses the REST API to manipulate all information in the post object, so hiding terms from the category, tags, or a custom taxonomy meta box can be achieved by removing those terms from REST API responses. One hook that makes this easy is the rest_{taxonomy}_collection_params filter. Here is an example that… Continue reading Hiding Specific Terms When Creating or Editing Posts

This is the collection of all the WordPress memes I’ve created. You Should Make Plugins Is This a PHP File? But Her Editors

I was surprised to learn that when editing a page using Elementor‘s page builder, is_admin() returns false. The reason for this is that Elementor is loading the page in an <iframe> element as if it were being viewed on the front-end. Use code like this to detect when posts or pages are being edited in… Continue reading Why Elementor Disobeys is_admin()

Here is a comment I just requested be added to the bottom of the register_setting() page. If you plan to use your setting in the REST API, use both the rest_api_init and admin_init hooks when calling register_setting() instead of just admin_init. The show_in_rest argument is ineffective when hooked into admin_init alone. Corey Salzano Someday, when my comment is approved, you’ll be able to see it on… Continue reading Using register_setting() and the REST API
