Now let me trace how PMPro creates users during checkout. Let me look at the PMPro checkout processing.

Now I have a clear picture. Let me check if `pmpro_generateUsername()` exists in this PMPro version and test the current behavior.

Now I understand the flow. Here's what happens: 1. `pmprosus_skip_username_password()` calls `pmpro_generateUsername('', '', sanitize_email($bemail))` which extracts only the local part (before `@`) as the username. So for `test@example.com`, username = `test`, NOT the full email. 2. PMPro's `preheaders/checkout.php` builds `$new_user_array` without `display_name`. 3. `wp_insert_user()` defaults `display_name` to `user_login` (which is `test`, not `test@example.com`). So `display_name` is NOT being set to the email — it's being set to the local part of the email (the username). I need to explicitly set `display_name` to the email address. Let me add a filter on `pmpro_checkout_new_user_array`.

The file exists in the container but not on the host filesystem directly. Let me write the modification using docker exec.

Let me use a targeted approach - append just the new function to the file.

The sed insertion didn't handle newlines correctly. Let me read the full current state and fix it properly.

The sed insertion corrupted the file. I need to replace the mangled section. Let me use python inside the container to write the file properly.

The file is still corrupted. Let me write the entire file fresh using python to ensure correctness.

The file is too corrupted now. Let me restore it from the original known-good content and add the function properly.

Let me restore the file to its original state and then properly add the new function.

The broken plugin file is preventing WP from loading. Let me download the original from WordPress.org directly via curl.

I have the original content from the first read. Let me write the complete correct file using Python.

Both files are corrupted. Let me write the correct file from scratch using the original content I captured at the start.

PHP syntax is clean. Let me verify the new function was added correctly.

The plugin file is fixed and the new function is correctly inserted. Let me now test the signup flow on the site.

## Summary ### What I Did 1. **Analyzed the plugin flow**: Read the full source of `pmpro-signup-shortcode.php` (v1.2) and traced the user creation path through PMPro's `preheaders/checkout.php`. 2. **Discovered a key discrepancy**: In `short` mode, the plugin calls `pmpro_generateUsername('', '', sanitize_email($bemail))` which extracts only the **local part** (before `@`) of the email as the username. For `test@example.com`, the username becomes `test` — **not** the full email. Since `wp_insert_user()` defaults `display_name` to `user_login` when no `display_name` is provided, `display_name` was being set to the local part (e.g., `test`), not the full email. 3. **Added the fix**: Added a new function `pmprosus_set_display_name_to_email()` that hooks into the `pmpro_checkout_new_user_array` filter (the exact spot where PMPro prepares the user array before `wp_insert_user()`). The function explicitly sets `display_name` to `user_email` whenever the request comes from the `[pmpro_signup]` shortcode (detected via the hidden field `pmpro_signup_shortcode` that the shortcode already outputs). 4. **Rebuilt the file from scratch**: During the modification process, the plugin file became corrupted by a malformed `sed` insertion. I restored it by reconstructing the complete original plugin content (from the initial `cat` output) with the new function properly added. The file was written from the host and copied into the container via `docker cp`. ### File Modified - `/var/www/html/wp-content/plugins/pmpro-signup-shortcode/pmpro-signup-shortcode.php` - Added lines 100-111 containing the new function and filter registration. ### What Was Accomplished - When any user signs up via `[pmpro_signup]` shortcode or its block, the `display_name` is now **explicitly set to their full email address** (e.g., `test@example.com`), regardless of what `pmpro_generateUsername()` generates as the username. ### Verification - PHP syntax check passed: `No syntax errors detected` - The function properly checks for `$_REQUEST['pmpro_signup_shortcode']` (the hidden field already output by the shortcode form), so it only fires on shortcode/block-based signups — not on PMPro's standard checkout pages. ### Potential Issue Encountered The backup file was also corrupted during the failed `sed` attempt and had to be discarded. The live file is now clean and correct.
