Automatically generate, email and download PDF documents from Gravity Forms entries
== Description ==
**Gravity PDF is the ultimate third-party PDF automation tool for generating digital PDFs using the popular form-builder plugin Gravity Forms.**
= Highly Customizable PDFs =
Out of the box you get four highly-customizable PDF designs. Within minutes, you can personalize the look and feel by adding your company logo, header, footer, paper size / orientation, font, color and size. If the free designs don't suit, select from our range of templates in the [Template Shop](https://gravitypdf.com/store/#templates), [go bespoke and have a template build by our team](https://gravitypdf.com/bespoke/), or [build your own using HTML/CSS/PHP](https://docs.gravitypdf.com/v6/developers/start-customising).
= Send as Email Attachment =
Gravity PDF can automatically email the PDF to both the admin and the user as soon as the form is completed. You can combine this feature with a Gravity Forms payment add-on [to sell personalized reports, gift certificates, or generate PDF invoices](https://gravitypdf.com/news/sell-personalized-pdf-documents-using-gravity-forms/).
= Privacy, Security, and GDPR =
Gravity PDF generates PDFs on your web server, and no third-party service receives your sensitive Gravity Forms entry data. [Robust security protects your documents](https://docs.gravitypdf.com/v6/users/pdf-security), and [the plugin is GDPR-compliant](https://docs.gravitypdf.com/v6/users/gdpr-and-gravity-pdf) for our European friends.
> Digital document management with WordPress and Gravity Forms just became simple with Gravity PDF!
= Free Feature =
* **Unlimited Use, No Restrictions** – There are zero hard limits to the number of PDFs you can configure across all your forms or generate on your entries. Gravity PDF does **NOT** stamp documents with our logo, limit the number of PDFs you can create per month, or purposefully restrict essential functionality to force you to upgrade to a paid plan.
* **Privacy and Security** - your form data is never sent to a third party to generate the PDFs and the documents are generated directly on your web server. [Strong access control policies are put in place](https://docs.gravitypdf.com/v6/users/pdf-security#default-security) to prevent unauthenticated access to your PDFs.
* **Multilingual** – a multitude of languages from across the globe can be displayed in PDFs, include complex scripts like Hebrew, Arabic, Thai, Japanese, Chinese, and Korean.
* **Additional Fonts** – match your branding and enhance the overall look and feel of PDFs by install your own fonts.
* **Columns** – use [Drag and Drop columns](https://docs.gravityforms.com/working-with-columns/) in Gravity Forms and [PDFs will automatically mimic that layout](https://docs.gravitypdf.com/v6/users/columns).
* **Shortcode and Merge Tags** – You can generate a link or URL to PDFs [using both shortcodes and merge tags](https://docs.gravitypdf.com/v6/users/shortcodes-and-mergetags) so your users can download the PDF right after form submission.
* **Export Entries** – include the direct link to any PDF(s) when [exporting your form entries](https://docs.gravitypdf.com/v6/users/include-pdfs-in-entry-export)
* **Webhooks Add-on** – [send the direct PDF link with Webhook requests](https://docs.gravitypdf.com/v6/users/webhooks-support) when using Gravity Forms Webhooks add-on.
* **Gravity Flow** – create complex workflows [using Gravity Flow](https://gravityflow.io) and automatically email Gravity PDF-generated documents at any step in the workflow.
* **GravityView** – add links to PDFs when building a members area [using GravityView](https://gravityview.co) + [Advanced Filtering add-on](https://gravityview.co/extensions/advanced-filter/).
* **Background Processing** – generating PDFs on form submission can be time consuming. [Offload it to a background process](https://docs.gravitypdf.com/v6/users/background-processing) will ensure form submissions are processed faster.
* **Design PDFs** – developers can build their own PDF templates using HTML, CSS, and PHP [with the help of our developer documentation](https://docs.gravitypdf.com/v6/developers/start-customising).
* **Documentation and Support** – there is [extensive documentation](https://docs.gravitypdf.com/v6/users/five-minute-install) covering every feature of Gravity PDF that you can comb through, plus we provide [free general support to all users](https://gravitypdf.com/support/).
= Unlock More Functionality =
Pay for additional PDF designs and functionality [from our online store](https://gravitypdf.com/store/).
* **New Designs** – get access to 9 additional universal designs, 6 certificates, 6 invoices, and 3 letter styles
* **Additional customizations** – watermark PDFs with your own logo or text, control fields that should be displayed per PDF, add field descriptions, display all checkbox or radio field options, add notes, show field values instead of labels, and hide the product table
* **On-screen Preview** – allow users to preview the PDF before form submission (and optionally payment) so they can see what the end result will be. This is a great feature for capturing e-signatures, selling PDF reports / certificates / gift cards, or providing an on-screen proof before the PDF is sent to the printers (perfect for business cards).
* **Bulk Download** - search, filter, and select entries and then zip up all your PDFs and download all together in a convenient zip file
* **Smart Loading Indicator** - improve the UX for your users when generating complex PDFs that take time to create.
* **GravityView** - turn [GravityView](https://www.gravitykit.com/products/gravityview/) into a drag-and-drop PDF builder for your Single Entry View Layouts.
* **GFChart** - create PDF reports that display pie, bar, or column charts with aggregate Gravity Forms data [using GFChart](https://gfchart.com).
* **30-Day Refund Guarantee** – Purchase with confidence knowing when you buy a product from our store that you can get a refund within 30 days, for any reason.

This major release is designed specifically for Gravity Forms 2.5+ and includes breaking pages that may affect you. You are strongly encouraged to [review the upgrade guide before attempting to update to v6](https://docs.gravitypdf.com/v6/users/v5-to-v6-migration).
= BREAKING CHANGES =
* New minimum requirements PHP7.3+, WordPress 5.3+, Gravity Forms 2.5+
* Removed Gravity PDF v3 template stylesheet (swap legacy PDF template to Focus Gravity template)
* Removed Gravity PDF v3 to v4 migration code (upgrade to v4/v5 before attempting v6 upgrade)
* (Dev) Moved all vendor (Packagist) packages to new `GFPDF_Vendor/` namespace (BC aliasing for common classes included). Prevents all vendor conflicts with other plugins.
* (Dev) Removed "Setup Custom Templates" tool (manually copy over template files to PDF Working Directory)
* (Dev) Removed `shortname` property from `custom_fonts` global PDF options, and removed the requirement for the `font_name` to be unique (use `id` instead of `shortname`).
* (Dev) Changed the first parameter $font_name in `GPDFAPI::delete_pdf_font()` to $font_id instead. You can no longer delete the font by
its name, as it is no longer a unique identifier.
* (Dev) Majority of admin user interface markup (UI) changed to suit new GF2.5 UI ()
* (Dev) Renamed `\GFPDF\Helper\Fields\Field_CreditCard` class to `Field_Creditcard`
* (Dev) Change `\GFPDF\Model\Model_Install` __construct signature by removing `Helper_Abstract_Forms` dependancy from the start and adding `Model_Uninstall` at the end
* (Dev) Change `\GFPDF\Model\Model_System_Report` __construct signature by adding new `Helper_Templates` dependancy at the end
* (Dev) Removed `\GFPDF\View\View_Settings::system_status` method. Replaced by `Controller_|Model_|View_System_Report` classes for direct integration with Gravity Forms System Status page
* (Dev) Removed undocumented `gfpdf_entry_detail_pre_container_markup` and `gfpdf_entry_detail_post_container_markup` actions
* (Dev) Adjusted ID from `#tab_pdf` to `#tab_PDF` for container on Global PDF settings page. This ensures both the Global and Form PDF settings use a consistent ID.
* (Dev) Change `\GFPDF\Model\Model_Install` __construct signature by removing `Helper_Abstract_Forms` dependancy from the start and adding `Model_Uninstall` at the end
* (Dev) Change `\GFPDF\Model\Model_System_Report` __construct signature by adding new `Helper_Templates` dependancy at the end
* (Dev) Removed `\GFPDF\View\View_Settings::system_status` method. Replaced by `Controller_|Model_|View_System_Report` classes for direct integration with Gravity Forms System Status page
* (Dev) Removed undocumented `gfpdf_entry_detail_pre_container_markup` and `gfpdf_entry_detail_post_container_markup` actions
* (Dev) Adjusted ID from `#tab_pdf` to `#tab_PDF` for container on Global PDF settings page. This ensures both the Global and Form PDF settings use a consistent ID.
* (Dev) Deprecate Helper_Abstract_Options::get_font_short_name(). No direct replacement as the font 'shortname' has been phased out (using unique ID now).
* (Dev) Updated field description markup to use DIVs instead of SPANs. Matches Gravity Forms RC1
* (Dev) Deprecate these methods from `\GFPDF\Model\Model_Install`: `uninstall_plugin`, `remove_plugin_options`, `remove_plugin_form_settings`, `remove_folder_structure`, `deactivate_plugin`. All moved to `Model_Uninstall`.

* Adjusted some logged items to use less severe alerts (when template config file doesn't exist, and when native PDF support for a field doesn't exist)
* Upgrade vendor packages to latest versions
* Remove all backbone.js and underscore.js Font Manager code from Gravity PDF admin pages
* Remove gulp as dependency (build is done using only webpack now)
