E2Pdf

Use E2Pdf to design and fill a PDF, then let WPsigner collect the signature, audit trail, and certificate.

E2Pdf is not bundled. It is a separate plugin (e2pdf.com). WPsigner never ships E2Pdf inside the product ZIP.

Admin path: WPsigner → Integrations → Formidable Forms (there is no E2Pdf card in the hub)

Note

Requires WPsigner 3.2.12+, Formidable Forms (Lite or Pro), and E2Pdf active on the same site. The native E2Pdf ↔ Formidable extension that ships with E2Pdf is enough — you do not need a Formidable add-on from WPsigner.

---

What this integration is

E2Pdf already knows how to turn a Formidable entry into a filled PDF. WPsigner takes that file and runs the signing workflow.

Formidable Form submitted
  → E2Pdf fills its template (dataset = entry ID)
  → WPsigner copies the PDF into secure storage
  → Empty signature field added (last page by default)
  → Open the signing page  or  email the signing request

Piece	Who owns it
PDF layout and field mapping	E2Pdf
Form capture	Formidable Forms
Signer, delivery, audit, certificate	WPsigner

This is a bridge, not a second document engine. Choose one source per feed:

Mode	When to use
E2Pdf + feed	The PDF already lives in E2Pdf
WPsigner PDF template	You map fields in WPsigner
Content signing	The form itself is the contract

A feed can use a WPsigner template or an E2Pdf template, not both.

---

What it is not

Expectation	Reality in 3.2.12
E2Pdf inside the WPsigner ZIP	Not included. Install E2Pdf yourself
A WPsigner → Integrations → E2Pdf screen	Not in this release. Use the Formidable feed
Gravity / Woo / CF7 / WPForms E2Pdf templates	Not wired. Only Formidable extension templates
WPsigner remapping E2Pdf fields	Field mapping stays in E2Pdf
Applying a signature already drawn on the form	E2Pdf feeds add an empty signature box for the signing page
Deleting the PDF E2Pdf saved in uploads	WPsigner copies it. Upload files stay. Temp files are removed after the copy

Full Formidable workflows (OTP, content signing, merge tags): Formidable Forms.

---

Prerequisites

Plugin	Role
WPsigner Pro 3.2.12+	Creates the signing document
Formidable Forms Lite or Pro	Captures the entry (dataset)
E2Pdf	Fills the PDF ([e2pdf-save] / [e2pdf-attachment])

The Formidable Form must include:

Field	Required	Why
Name (person name, not Username)	Yes	Primary signer name
Email	Yes	Signing identity
Other fields	Optional	Mapped in E2Pdf, not in WPsigner

Do not add the WPsigner Signing field if you want the E2Pdf path. That field switches the form to content signing and skips template / E2Pdf feeds.

---

Setup

1. Create the E2Pdf template

1. Install and activate E2Pdf.
2. Open the E2Pdf template builder.
3. Set extension to Formidable and item to your form.
4. Place and map fields there (name, dates, text, tables, and so on).
5. Save the template. Activate it in E2Pdf if you want generation without E2Pdf’s inactive-template limits. Note its numeric ID if you will use a developer hook.

WPsigner lists templates from the e2pdf_templates table (Formidable extension only, not in the trash). Templates that are not yet license-activated in E2Pdf still appear, marked (not activated in E2Pdf).

2. Create the WPsigner feed

1. Go to WPsigner → Integrations → Formidable Forms.
2. Click New Feed.
3. Set:

Setting	What to choose
Feed name	Internal label (e.g. Lease — E2Pdf)
Formidable Form	The same form as the E2Pdf item
WPsigner template	Leave empty
E2Pdf template	The Formidable template from step 1
Document title	Optional. Supports {{signer_name}}, {{signer_email}}, {{date}}, {{company_name}}
Name field / Email field	Formidable fields for the primary signer
CC email field / Additional CC emails	Optional. Same CC rules as other feeds
After submit	Open signing page immediately, or send the signing email
Feed enabled	On

4. Click Save Feed.

The E2Pdf template dropdown appears when E2Pdf is detected (plugin, shortcodes, or e2pdf_templates table). Templates whose Formidable item matches the selected form stay visible; if none match, every Formidable template stays visible so a newly created template does not disappear.

WPsigner field mapping is hidden on E2Pdf feeds. E2Pdf already filled those values.

3. Test

Open for signing

1. Submit the form on the front end.
2. You should redirect to /insigner/{token}.
3. The PDF should show E2Pdf data. Signature / initials stay empty.
4. Sign and confirm WPsigner → Documents shows the file as completed.

Email

1. Submit the form.
2. The signer receives the signing-request email (no redirect).
3. Open the link and sign.

Rate limit: 10 documents per minute per form (shared with other Formidable feeds).

---

After submit

Option	What happens
Open signing page immediately	Document status sent. Formidable confirmation redirects to the signing URL. No signing email.
Send signing request by email	Document status sent. Each signer gets the email. Formidable shows its normal confirmation.

Same Formidable hooks as other template feeds: frm_after_create_entry, frm_success_filter, frm_redirect_url.

---

How WPsigner generates the PDF

On submit WPsigner runs, in order:

1. Filter wps_formidableforms_e2pdf_pdf_path — if you return a local PDF path, generation is skipped.
2. [e2pdf-save id="ID" dataset="ENTRY_ID" output="path" apply="true" savename="wps-frm-…" overwrite="true" format="pdf"]
3. Look up the file under uploads/e2pdf/tpl/{template_id}/save/
4. Same shortcode with output="url", then the same folder lookup
5. Fallback [e2pdf-attachment id="ID" dataset="ENTRY_ID" apply="true"]

apply="true" is required when those shortcodes run from PHP (do_shortcode). Relative /wp-content/… paths and uploads URLs are accepted. Temporary copies are allow-listed so a path like C:/foo cannot match C:/foo_evil.

The returned value must be a readable local PDF:

• Path under uploads, wp-content, or the system temp directory
• Or an uploads URL that maps to that path
• File header must start with %PDF-

WPsigner then:

1. Encrypts a copy into secure storage (OpenSSL AES-256-GCM)
2. Creates the document + signer(s)
3. Adds an empty signature field
4. Applies CC emails
5. Delivers (redirect or email)

It does not delete E2Pdf files stored in uploads. Files under the system temp directory are deleted after the copy.

---

Signature placement

By default WPsigner adds one required signature field on the last page:

Property	Default
Page	Last page of the E2Pdf file
Position	x = 50, y = 680 (plus 80px per extra signer)
Size	220 × 70

Change this with wps_formidableforms_e2pdf_signature_fields (see hooks). Additional signers on the feed each get their own box.

---

Site weight and System Status

E2Pdf installed?	What WPsigner loads
No	A PHP is_active() check. No front-end JS. Dropdown hidden
Yes, no E2Pdf feed	Admin can list templates. Front-end form is unchanged
Yes, feed enabled	One shortcode run after the Formidable entry is created

WPsigner → Tools → System Status lists E2Pdf next to the form plugins so support can see whether the companion plugin is active.

---

Developer hooks

All hooks fire only on the Formidable → E2Pdf path (WPsigner 3.2.12+).

wps_formidableforms_before_process

Action. After the entry is loaded, before any feed runs.

add_action('wps_formidableforms_before_process', function ($entry_id, $form_id, $entry, $form) {
    // Inspect the submission
}, 10, 4);

wps_formidableforms_e2pdf_template_id

Filter. Override or supply the E2Pdf template ID. Also used when no feed is saved (auto feed from Name + Email).

A stored WPsigner template_id is not overridden by this filter.

add_filter('wps_formidableforms_e2pdf_template_id', function ($template_id, $feed, $entry, $form) {
    if ($template_id > 0) {
        return $template_id;
    }
    if (!empty($feed['template_id'])) {
        return 0;
    }
    return 12;
}, 10, 4);

wps_formidableforms_e2pdf_templates

Filter. Change the admin dropdown list ($templates, $form_id).

wps_formidableforms_e2pdf_shortcode

Filter. Replace the [e2pdf-save … apply="true"] string ($shortcode, $template_id, $entry_id, $feed, $form).

wps_formidableforms_e2pdf_attachment_shortcode

Filter. Replace the fallback [e2pdf-attachment …] string.

wps_formidableforms_e2pdf_pdf_path

Filter. Return an absolute local PDF path to skip shortcodes ($path, $template_id, $entry_id, $feed, $form). Empty string = generate.

wps_formidableforms_e2pdf_signature_fields

Filter. Change empty signature fields ($fields, $document_id, $signer_id, $feed, $form, $index).

add_filter('wps_formidableforms_e2pdf_signature_fields', function ($fields, $document_id, $signer_id, $feed, $form, $index) {
    $fields[0]['page_number'] = 1;
    $fields[0]['position_x']  = 80;
    $fields[0]['position_y']  = 640;
    $fields[0]['width']       = 220;
    $fields[0]['height']      = 70;
    return $fields;
}, 10, 6);

wps_formidableforms_e2pdf_generated

Action. After a valid PDF path exists, before the WPsigner document is created ($pdf_path, $template_id, $entry_id, $entry, $form, $feed).

wps_formidableforms_e2pdf_document_created

Action. After the document exists ($document_id, $entry_id, $entry, $form, $feed, $template_id, $stored_path).

Shared Formidable / completion hooks

Hook	When
wps_formidableforms_document_created	Same document-created event as PDF-template feeds
wps_document_completed	Signer finished
wps_pdf_completed	Signed PDF is ready

add_action('wps_formidableforms_document_created', function ($document_id, $entry_id, $entry, $form, $feed) {
    // Runs for WPsigner templates and E2Pdf feeds
}, 10, 5);

Troubleshooting

Issue	Cause	Solution
E2Pdf template dropdown missing	E2Pdf inactive	Install/activate E2Pdf. WPsigner does not bundle it
Template created in E2Pdf but missing from the feed	Extension is not Formidable, template is in trash, or the form item does not match	Set extension to Formidable and item to this form. WPsigner lists inactive (not license-activated) templates
Cannot save the feed	No WPsigner template and no E2Pdf template, and the form is not content signing	Select an E2Pdf template or a WPsigner template
No document created	Feed disabled, missing name/email, or E2Pdf returned HTML	Enable the feed; map Name + Email; use a Formidable E2Pdf template; check debug.log
Wrong or empty PDF	Template extension is not Formidable, or item is another form	Match extension + item to the submitted form
Signature box in the wrong place	Default last-page coordinates	Filter wps_formidableforms_e2pdf_signature_fields
Two documents from one submit	Content-signing field on the form, or a second feed	Remove WPsigner Signing for E2Pdf mode; keep one enabled feed
Redirect did not happen	Delivery set to email, or generation failed	Use Open signing page immediately; confirm the PDF path is valid
Rapid tests stop creating docs	Rate limit	Max 10 / minute / form
CC missing	Same as other Formidable feeds	Set CC email field; do not paste [x] shortcodes in Additional CC emails

Debug log

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);

Look for [inSigner FormidableE2Pdf] (and [inSigner FormidableForms]) in wp-content/debug.log.
