Описание

This plugin gives WordPress Admin Panel users the ability to add fillable PDF attachments to email messages and form submission responses of Contact Form 7.

If the PDF attachment has a PDF form, the plugin allows users to add fields to the CF7 form and/or link them to fields in the PDF. The plugin also allows the attached PDF files to be embedded with images supplied by the CF7 form fields. The filled PDF files can be saved on the web server.

When your website visitor submits the CF7 form, the form in the PDF file is filled with CF7 form information, images are embedded and the resulting PDF file is attached to the CF7 email message.

An external web API (https://pdf.ninja) is used for filling PDF forms (free usage has limitations). An Enterprise Extension, which enables performing all PDF operations locally on your web server (no external web API), is available.

Known problems,
* Some UTF-8 (non-latin) characters, checkboxes and radio buttons don’t render properly after being filled. Almost always the problem lies with the PDF viewers not rendering them correctly. There is a workaround in the works, however, currently it remains in development.
* Some third party plugins break the functionality of this plugin (see a list below). Try troubleshooting the problem by disabling likely plugins that may cause issues, such as plugins that modify WordPress or Contact Form 7 in radical ways.
* Possible issues with checkbox multiselect

Known incompatible plugins,
* Contact Form 7 Live Preview
* Open external links in a new window
* Contact Form 7 Multi-step Pro (partial compatibility)
* WordPress Multilingual Plugin
* Contact Form 7 Skins

Special thanks to the following sponsors of this plugin,
* BrowserStack
* Momentum3
* G-FITTINGS GmbH

Часто задаваемые вопросы

Does this plugin allow my website users to work with PDF files?

No. This plugin adds features to the Contact Form 7 interface in the WordPress Admin Panel only.

Does this plugin require special software installation on the web server?

No. The plugin uses core WordPress features only. No special software or PHP extensions are needed. Working with PDF files is done through Pdf.Ninja API. It is recommended to have a working SSL/TLS certificate verification with cURL.

How are the CF7 form fields mapped to the PDF form fields?

There are two ways to map fields with this plugin. The field mapper tool allows you to map fields individually and, when needed, generate new CF7 fields on the fly. The tag generator tool maps to the fields in the PDF form using the random looking code in the CF7 field name that it generates. Here is the format: pdf-field-{attachment-id}-{human-readable-field-name}-{random-looking-code}. The ‘{attachment-id}’ can be ‘all’ to allow it to map to all PDFs attached to the CF7 form (in case you ever want to swap out the PDF file without needing to fix the generated tags). If you remove the random looking code, the field will no longer be mapped to the field in the PDF.

My fields are not getting filled, what is wrong?

If you reuploaded the PDF file and your mapping was using the old file ID then your mapping will no longer work and you will need to recreate it.

If you are using the field mapper tool, make sure the mapping exists in the list of mappings and the field names match. If you are using the tag generator tool, make sure the attachment ID matches (or is ‘all’) and the base64-encoded part of the tag name is unchanged.

If you renamed the PDF field, you will need to remove the old mapping and recreate the mapping with the new name.

My checkboxes and/or radio buttons are not getting filled, what is wrong?

Make sure your PDF checkbox/radio field’s exported value matches the value of the CF7 form’s checkbox tag. Usually, it is «On» or «Yes». If you need to display a different value in the CF7 form, use pipes.

Some PDF viewers don’t render checkboxes correctly in some PDF files due to incompatible PDF formatting. You may be able to solve this issue by recreating the PDF in a different PDF editor.

How do I remove the watermark in the filled PDF files?

Please see the Pdf.Ninja API website and the Enterprise Extension plugin.

How do I set up PDF form filling on my local web server?

Please see the Enterprise Extension plugin.

This plugin is ideal for automatically filling pdfs based on data entered by users. It is a good complement for CF7. You can even add a handwritten signature to your pdf form thanks to its compatibility with the "Contact Form 7 Signature Addon" plugin. So yes you will probably need the PRO version to remove the watermark but it is a good investment. And then the FREE version allows you to test all the features of this plugin. I just have a suggestion for a better compatibility with the "CF7 Conditional Fields PRO" plugin by Jules Colle. For this I will open a support topic.

If you need to use contact form 7 with PDF this is the best plugin out there. After numerous tries with all kinds of free and premium plugins, this is the far the best of them. The integration is perfect with API and contact form 7. Thanks for the plugin!

After extensive comparison I ended up selecting this plugin (PRO version without watermark at 49 USD/year) in order to get a PDF file from a Contact Form 7 form. The good points of this plugin are: - you are allowed to make all the testing you want before deciding if buying the PRO version without watermark (the free version is for unlimited testing only) - the linking between Contact Form 7's fields and the fields in the PDF is easy - you can upload different PDF files and have them filled at once (one field's data can go to several places in the same PDF or, should be, in different PDFs) - I could create the PDF file and its fillable fields from the free LibreOffice Writer (it's similar to Microsoft Word) - You can decide if the created PDF is still fillable or not ("flattened") - I can add that you can have only certain fields still fillable if you make some of them "read only" while creating the PDF (in LibreOffice Writer) and set the whole PDF created by this plugin "not flattened") Some important missing features are: - It is not possible to "trigger" a specific PDF file based on a specific answer in the form (the only option is not to have a PDF at all if all the fields are empty) - that would be a very important feature in order to get only the PDFs you actually need based on your selection - While a Contact Form 7 field data can go to different places in a PDF, the opposite is not possible (it means that a PDF field can receive a data only from one specific Contact Form 7 field) - multiple selections do not work - you have to create several "multiple" selection (one on top of the other) where you really have only one selection for each one

Nothings worse than finding a great plugin, having a small issue and not getting any support. The support for this plugin was great with a response the next day. I had a minor issue which they helped me resolve quickly, and followed up after I had a second question just as quickly. Plugin and support both are great and was hard to find a plugin that does something similar, glad I got this working. 🙂

Upon installation the site went offline. When disabling the plugin's map on the server the website is back online. Don't install it.

This is a good and, if you need to fill in PDFs from the front end, useful plugin. The video tutorial needs a lot of work. It sounds like a text-to-voice implementation and runs so fast it is hard to keep up. But it hits the high points. When I figured out for my simple requirement I did not need all the "tools" it was a lot easier to set up. I created a CF7 form based on a PDF template I use. I was careful to give the CF7 form field names that matched exactly, the PDF form field names to make mapping easier. And it was a snap. Insert and Use all button worked perfectly. When I tested the CF7 form it worked perfectly and nano seconds later I received an email with the PDF form - filled in with data submitted on the CF7 form. The ONLY problem - for me - is that it watermarks the PDFs unless you lease the pro version. Lease as it pay yearly. Since I prefer not to use subscription software, this was not the solution I needed. If your preferences are different and you need to be able to fill in a PDF from the front end, this worked perfectly and without a lot of difficulty.
