Code Engine – PHP Snippets, AI Functions & Automation for WordPress vs AI Bot for bbPress

AI Bot for bbPress integrates seamlessly with your bbPress forums, allowing a configurable AI bot user to participate in discussions. The bot can be triggered by direct mentions (@YourBotUsername) or specific keywords within forum posts, leveraging context from the forum and optionally a remote WordPress site. Currently uses OpenAI’s ChatGPT API. Future versions will migrate to our AI HTTP Client library to provide multi-provider support (OpenAI, Anthropic, Gemini, Grok, OpenRouter) with a unified interface. Links: * Plugin Homepage – Visit the developer’s website * GitHub Repository – Source code, issues, and contributions * Support – Report bugs or request features Configuration After activation, navigate to Settings > Forum AI Bot in your WordPress admin area to configure the following options: OpenAI API Key: Your secret API key from OpenAI. Bot User ID: The WordPress user ID of the account the bot will use to post replies. System Prompt: Instructions defining the bot’s personality, role, and general behavior (e.g., “You are a helpful assistant for the Example Community forum.”). Custom Prompt: Additional instructions appended to every API request, useful for guiding specific response formats or context usage. Temperature: Controls the creativity/randomness of the AI’s responses (0 = deterministic, 1 = max creativity). Default is 0.5. Trigger Keywords: A comma-separated list of keywords (in addition to mentions) that will trigger the bot to respond. Local Search Limit: Maximum number of relevant posts/topics to retrieve from the local forum database for context. Default is 3. Remote REST Endpoint URL: The full URL to the search endpoint provided by the BBP Bot Helper plugin installed on your remote site (e.g., https://your-main-site.com/wp-json/bbp-bot-helper/v1/search). Leave blank to disable remote context. Remote Search Limit: Maximum number of relevant posts to retrieve from the remote endpoint for context. Default is 3. Forum Access Control: Choose whether the bot responds in all forums or only selected ones. When set to “Selected Forums Only”, you can choose specific forums where the bot will be active. External Services This plugin connects to the OpenAI API to generate responses for the AI bot. This is essential for the plugin’s core functionality of providing AI-driven replies in bbPress forums. Service: OpenAI API (specifically the Chat Completions endpoint). Purpose: To generate intelligent and contextually relevant responses based on forum discussions and configured prompts. Data Sent: When the bot is triggered (by a mention or keyword), the following types of data are sent to the OpenAI API: The content of the post that triggered the bot. Relevant conversation history from the current topic (including post content and author usernames/slugs). Contextual information retrieved from the local WordPress database (titles, snippets, and URLs of relevant posts/pages based on keyword matching). If configured, contextual information retrieved from a remote WordPress site via the BBP Bot Helper plugin (titles, snippets, and URLs of relevant posts/pages). The system prompt, custom prompt, and temperature settings configured in the plugin’s admin page. The structure of your bbPress forums (forum names, topic names, and their hierarchy). The current date and time. When Data is Sent: Data is sent only when the bot is triggered to generate a response. This occurs after a user posts a new reply or topic that meets the trigger conditions (mentioning the bot or containing a specified keyword). OpenAI API Terms of Service: https://openai.com/policies/terms-of-service OpenAI API Privacy Policy: https://openai.com/policies/privacy-policy It is important to have an active OpenAI API key with sufficient credits for the bot to function. Please review OpenAI’s policies to understand how they handle the data sent to their API. If the “Remote REST Endpoint URL” is configured, the plugin will also send search queries (derived from the conversation) to that endpoint to fetch additional context. This endpoint is typically on another WordPress site you control and that runs the companion “BBP Bot Helper” plugin. No user-specific data is sent to this remote endpoint beyond the search terms. The data received from this endpoint is then included in the information sent to the OpenAI API as described above.

Code Engine is a snippets manager that doesn’t stop at snippets. Yes, it runs your PHP and JavaScript exactly where and when you want: frontend, backend, on a schedule, or inside your content. But its real magic is what happens after you write a function: the same little piece of code instantly becomes a tool your AI chatbots can call, a step you can drag into a visual workflow, and an endpoint the outside world can trigger. One function, three superpowers. Most “code snippets” plugins stop at a textarea and a toggle. Code Engine treats your functions as first-class building blocks for the whole Meow Apps ecosystem, and for anything that can speak REST. Think out of the box, let your creativity flow, because the possibilities really are endless! ✨ For more, check the official website and come say hi on the Discord. Quick Intro Hello! ☀️ I built Code Engine because I was tired of pasting mystery snippets into functions.php and praying. I wanted a place where small bits of code are organized, safe, AI-assisted, and reusable everywhere. Here’s the idea. You write a function (or let the AI write it for you from a plain-English description). That function immediately shows up in three places: AI Engine: your chatbots and MCP clients (Claude, ChatGPT, Claude Code) can call it as a tool, with real arguments. Ask “how many orders shipped today?” and your chatbot runs your function to answer. Workflow Engine: your function appears in the step picker as its very own block. Drag it onto the canvas, wire it between an AI step and a Slack step, done. No glue code. REST / External tools: give it a secure endpoint and a token, then trigger it from Make.com, n8n, Zapier, a cron job, or a webhook. You never wrote an “integration.” You just wrote a function. Code Engine did the rest. 🤝 Core Modules 🧩 Snippets Manager Backend, Frontend, Persistent, Scheduled, Functions, and in-content (PHP/JS) snippets, all in one clean dashboard with tags, search, scope filters, and priorities. 🪄 AI-Assisted Coding Describe what you want in plain English and let AI Engine write the snippet: code, name, arguments, and scope included. Refine existing code or implement it straight from your comments. 🤖 Functions as AI Tools Every Function snippet becomes a function-calling tool and an MCP tool, so your AI Engine chatbots (and external AI agents) can actually do things on your site, not just talk. 🔀 Functions as Workflow Steps Workflow Engine surfaces each of your functions as its own draggable step. Your custom logic becomes a first-class citizen on the automation canvas. 🌐 External Access (REST) Expose any runnable snippet through a secured REST endpoint with a bearer token. Perfect for Make.com, n8n, webhooks, and scheduled external jobs. 🛡️ Safe Mode A snippet that throws a fatal error is automatically caught and disabled before it can take your site down. Code with confidence. ⏰ Scheduling Run a snippet daily at a chosen time via WP-Cron (reports, cleanups, syncs) without touching the server crontab. 🧱 Code Blocks & Shortcodes (Pro) Drop PHP or JS straight into a post or page with a Gutenberg block or the [code-engine] shortcode, with safety guards. 🧩 Snippets, the way they should be Code Engine organizes your code by scope, so each snippet runs exactly where it belongs: Persistent: runs everywhere (frontend and backend). Your everyday “add this to functions.php” code, but managed. Frontend: runs only on the public site. Backend: runs only in the admin. Function: a named, callable function with typed arguments and defaults. This is the reusable building block (see below). Scheduled: runs on a WP-Cron schedule, at the hour and minute you pick. Content (PHP / JS): runs inside a specific post or page, via a Gutenberg Code Block or the [code-engine] shortcode (Pro). Everything is searchable, taggable, sortable by priority, and importable/exportable. The CodeMirror editor gives you proper syntax highlighting and keyboard shortcuts (Cmd+S to save, Cmd+Enter to run). A nikic/php-parser pass validates your PHP before it ever runs. 🪄 Let AI write it for you Don’t feel like writing the boilerplate? Describe the snippet in plain language and Code Engine, powered by AI Engine, generates the whole thing: the code, a sensible name, a description, the right scope, and, for functions, the argument list with names, types, and defaults. Already have code? Ask the AI to modify it from a prompt, or write a few comments describing what you want and let it fill in the implementation. It’s pair programming, right inside your dashboard. ✨ The big idea: write once, use everywhere This is what makes Code Engine different. A Function snippet is not just code you call from other code. It’s a reusable capability that the rest of your stack can plug into. The moment you save it, the same function is available in three places at once: 1. As an AI tool, for chatbots and AI agents With AI Engine active, your functions are exposed through function calling and over MCP (Model Context Protocol). Your on-site chatbot can run them mid-conversation, and external AI agents (Claude, Claude Code, ChatGPT, OpenClaw) can call them too. Want a chatbot that checks stock, looks up a booking, or kicks off a process? Write the function; the chatbot gains the skill. 2. As a workflow step, for automation With Workflow Engine, every active function shows up in the Add-step picker as its own block, named after your snippet, with one input per argument. Drag it onto the canvas and wire it between other steps: an AI step that summarizes, your function that saves, a Social Engine step that posts. There’s also a generic “Execute snippet (by ID / by name)” step when you want to call one dynamically. You never write integration code; your function is the integration. 3. As a REST endpoint, for the outside world Give a snippet a custom endpoint name and a bearer token, and it’s instantly callable from anywhere: POST /wp-json/code-engine/v1/snippets-endpoint/your-endpoint Pass arguments as JSON in the body, secure it with a token, and trigger it from Make.com, n8n, Zapier, GitHub Actions, or a humble cron job. Automation without a middleware bill. 🛡️ Safe by default Running arbitrary code is powerful, so Code Engine takes safety seriously: Safe Mode catches fatal errors and auto-disables the offending snippet, so a typo never white-screens your site. REST whitelisting means global snippets only run on trusted REST routes by default, so you choose what to open up. Per-snippet tokens secure your external endpoints. Validation with a real PHP parser before code is saved. For developers who want fewer guardrails, there’s a “Bypass REST Security” option and filters (mwcode_rest_authorized, mwcode_rest_whitelist) to tailor exactly what’s allowed. Works beautifully with the Meow Apps family Code Engine is one engine in a connected set, each one useful alone, magical together: AI Engine: chatbots, content generation, and MCP. Turns your functions into AI tools. Workflow Engine: visual automation. Turns your functions into draggable steps. SEO Engine: smart, lightweight AI SEO. Social Engine: schedule and automate social posts. Why Code Engine? Reusable, not throwaway Other snippet plugins give you a place to paste code. Code Engine gives you a place to build capabilities that your AI, your workflows, and your external tools can all use. Native to WordPress Clean, fast, and built the WordPress way. No clunky external dashboards, no bloat. AI-native Write snippets with AI, expose them to AI. The whole loop lives in your wp-admin. Developer friendly REST API, MCP tools, function calling, scheduling, import/export, and plenty of filters to hook into. Cared for Part of the Meow Apps family, with regular updates and a real human behind it. 💕
