* BFB Settings -> Front-End Booking Form Post-Processing Hooks |
| 4 |
* |
| 5 |
* This file registers hook callbacks that apply **BFB form settings** (decoded JSON settings array) to the final booking form HTML that is rendered on the front-end. |
| 6 |
* |
| 7 |
* These hooks are executed inside `WPBC_FE_Form_Body_Renderer::render()` in this order: |
| 8 |
* |
| 9 |
* 1) `wpbc_booking_form__body_html__before_postprocess` --> raw **form body HTML only** (no injected calendar/captcha/extra calendars yet). |
| 10 |
* |
| 11 |
* 2) `wpbc_booking_form__html__before_wrapper` --> composed **form HTML** where calendar/captcha/extra calendars already injected, |
| 12 |
* |
| 13 |
* 3) `wpbc_booking_form__wrapped_html__before_inline_scripts --> full **wrapped HTML** including the wrapper `<div class="wpbc_container wpbc_form ...">` and the `<form>` markup |
| 14 |
* |
| 15 |
* 4) `wpbc_booking_form__wrapped_html__after_inline_scripts` --> the final HTML after inline scripts are appended. |
| 16 |
* |
| 17 |
* Notes: |
| 18 |
* - `$bfb_settings` is expected to be an array like: |
| 19 |
* [ |
| 20 |
* 'options' => [ 'booking_form_theme' => 'wpbc_theme_dark_1', ... ] |

* ] |

| 34 |
* |
| 35 |
* Purpose: |

* - If the form body contains the BFB root element (class `wpbc_bfb_form`), |
| 37 |
* inject CSS Custom Properties (variables) into its `style` attribute. |
| 38 |
* |

* This hook must run **before** legacy post-processing inserts calendars/captcha, because it targets the BFB body root and should not depend on wrapper existence. |

* Expected `$bfb_settings` format: - `$bfb_settings['css_vars']` is an associative array: `--var-name` => `value`. |

* - The wrapper container does not exist until `WPBC_FE_Form_Wrapper::wrap()` runs, therefore this must be executed on the wrapped HTML stage. |

| 106 |
* Potential limitations: |
| 107 |
* - This implementation supports a **single** class value. If you plan to support multiple |
