Previously on the CogitActive Saga:
A harmless suggestion on the surface. A tiny footnote. But it contained the seed of a much bigger problem — one I hadn’t yet realized.
When I imagined the “doorbell,” I had a very precise behavior in mind. It should appear exactly where the comment form normally sits, and—crucially—only when comments are closed. Nothing more, nothing less. But as you already know, if you’ve been following this bonus project mini‑series, reality had other plans. The widget insisted on showing up even when comments were still open, creating the absurd spectacle of “The comments are closed” immediately followed by a button politely inviting readers to “Please, leave a comment.” And to make matters worse, it wasn’t even appearing in the right place. By default, the plugin simply tacks the widget onto the end of the post—in the_content—which is nowhere near the comment form’s rightful location.
The diagnosis was clear, and so was the cure. The plugin does allow inserting the widget via PHP, which would let me hook it directly into the theme at the correct spot. Combine that with a simple conditional—! comments_open()—and both the where and the when problems vanish. Elegant. Precise. Reliable. In theory.
Except that PHP is not exactly my native language. I haven’t touched it since that fateful summer of 2020, when CogitActive slipped into what I can only describe as “survival mode.” So instead of rolling up my sleeves and working through the logic step by step, I reached for what looked like a shortcut: I asked two Artificial Intelligence helpers to guide me. That shortcut quickly revealed itself to be a detour. A scenic one, perhaps, but still a detour—full of almost‑correct answers, confidently delivered misunderstandings, and technically Accurate but completely Irrelevant workarounds that neatly sidestepped the actual requirements. In short: a tour of everything but the solution.
And that brings me to today’s post, where—having exhausted the machines—I turn to you, dear reader. Before I can ask for help, though, I need to restate the problem in precise terms. Not the symptoms, not the frustrations, but the actual requirements the doorbell metaphor depends on. These are the functional, behavioral, and experience‑level conditions that must be met for this whole idea to make sense within the context of WordPress’s comment system:
The widget must appear only when comments are closed. The entire purpose of the “doorbell” is to request access when the door is locked; it must never appear when the comment form is already open.
The widget must appear exactly where the comment form normally appears. Not inside the post content, not before/after the article — but in the comment area, in the same place users expect to interact.
The whole point is to replace the missing form with a functional equivalent, not to scatter UI elements around the page and hope readers will make the connection. These two requirements—when and where—are the backbone of the entire doorbell idea. Without them, the metaphor collapses, the user experience becomes incoherent, and the widget becomes just another misplaced button.
Now, let me turn to the constraints—the technical boundaries that define what is possible, what is risky, and what is simply off‑limits. If the requirements describe what the doorbell must do, the constraints describe how I am allowed to implement it:
I do not want to modify single.php. Template edits disappear the moment the parent theme updates, and I have no intention of re‑patching files every time Twenty Seventeen receives a refresh. Yes, I have a child theme, but even then, I prefer not to touch templates at all. Overriding template parts “freezes” the parent theme’s updates, which is a polite way of saying: you’ve just taken responsibility for maintaining that file forever. That includes security fixes. That includes compatibility changes. That includes everything I do not want to manage.
I want to use hooks, not template overrides. This is a hard constraint. All logic should live in functions.php (of my child theme, obviously), cleanly contained, easy to maintain, and safely isolated from theme updates. No scattered edits. No fragile overrides. No future headaches.
But here is the big problem—the one that derails the entire plan. The Twenty Seventeen theme only loads the comments template when comments are open or when there are existing comments. If comments are closed and there are zero comments, the comments area does not load at all. WordPress simply omits it. No wrapper. No comment form. No place to hook the doorbell into. Nothing.
// If comments are open or we have at least one comment, load up the comment template.
if ( comments_open() || get_comments_number() ) :
comments_template();
endif;This is not a minor inconvenience. It is a structural absence. The very location where the doorbell must appear simply does not exist under the conditions where the doorbell is supposed to appear. And that, dear reader, is the heart of the challenge.
So, I’m setting the PHP challenge back on the table—same constraints, same objective—but with a different question in mind: can you outsmart the AIs? If you think you can place that widget exactly where it belongs, under the conditions I’ve described, without breaking the theme or the plugin, I would genuinely like to see how you’d do it.
Thank you for your help.
