Theme Inspector

by Melissa Cabral

Download
Description

A simple, lightweight plugin that displays useful technical information on pages and posts to aid in developing WordPress Classic themes. Provides quick access to things that are sometimes hidden, like post/page ID, slug, taxonomy terms, and post type slug. Theme Inspector tells you exactly what conditional tags are true on each view, and what template file loaded on each page view.

  • Use In Conjunction with the WP Template Hierarchy Document.
  • Theme Inspector is only visible to logged in Administrators.
  • Appears on the right-side of the Toolbar (admin bar).
  1. Simply unzip and upload to the wp-content/plugins’ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. There’s nothing to configure. Theme Inspector will automatically appear when you view your website as an Administrator. Look at the upper-right corner of the Toolbar (“Admin Bar”).
  4. Hover over “Theme Inspector” for a flyout-panel containing information about the page you are currently viewing.
I don’t see Theme Inspector! Where is it?

You must be logged in as an administrator, and viewing the Site (not the admin panel). It will appear on the admin bar.

Not working

Documentation says Theme Inspecor appears on right side when viewing web page as Admin. It is the light blue color with no text so it is not obvious that you need to click to use the theme builder.

Looks Helpful, no RTL support

By ibanner on February 16, 2021

This plugin looks like something I've been looking for, for quite some time. However it seems it doesn't play well with RTL sites. The popup with the info is aligned to the right side of the admin bar button, with causes some of the info to disappear out of view. I would be more than willing to reconsider my rating if this issue is solved.

Very useful

Awesome! Still works (with 4.9.8) Thx

Fantastic Tool!

By chzumbrunnen on September 18, 2018

Not only does it show the currently active template file (what some other plugins do too), but it shows where in the template hierarchy it is. Therefor it's very easy to know what template file to edit / replace in a child theme. Also it shows the post type, post id, true conditions... It's a fantastic developer tool and I highly recommend it Too sad that this plugin isn't that well known. It's the best of it's kind in my humble opinion.

The plug in is very useful: you always have all the info you need at your fingertip. Tech support is also very prompt.

Great Learning and Development Tool

By djpacmansd on September 3, 2016

It tells you what page template you're using which is really helpful when you're starting out and a great tool if you're a seasoned WP developer. Great plugin! Thanks!

The data you need, when you need it

By Anne Dorko (annedorko) on September 3, 2016

I use this on every custom theme project I work on now. It makes debugging 1,000x easier by letting you know exactly what WordPress is thinking on each page.

I haven't run into any user issues as of yet.

Must-have for Developers

By Josh Smith (joshsmith01) on September 3, 2016
