Slack Feed Meta

IntroductionUsageProperties

Introduction
The Feed Object meta for the Slack add-on is an associative array containing the properties which determine how the add-on should process the form submission.
$feed['meta'] = array(
'feed_name' => 'Your Feed Name',
'message' => 'Entry #{entry_id} ({entry_url}) has been added.',
'feed_condition_conditional_logic' => true,
'feed_condition_conditional_logic_object' => array(
'conditionalLogic' => array(),
),
);

Usage
We recommend accessing the $feed meta using the rgar() or rgars() functions, e.g.;
$conditional_logic_enabled = rgars( $feed, 'meta/feed_condition_conditional_logic' );

Properties

feed_name string
The feed name which appears on the add-ons feeds tab.

send_to string
The type of channel Slack will send the message to: Possible values: channel, group or user.

channel string

Slack Update for New API

SummaryEffect of Deprecation on Versions 1.12 and PriorUpgrade ProcessTeam Invite Feature Deprecation

Summary

On Feb 24th, 2021, Slack will be deprecating their older API methods in favor of their updated Conversations API.
Users of the official Gravity Forms Slack Add-on will need to update to version v1.13 or later to use the new API methods..
Failure to update will affect feed settings after the Slack API deprecation date of Feb 24.
The 「Team Invites」 feature offered in previous versions will no longer work as of this update. Refer to this section.

Effect of Deprecation on Versions 1.12 and Prior
Users who do not upgrade will no longer be able to modify their Slack feed settings after February 24th, as the API endpoints used to list channels and group IMs will not be accessible. Upgrading will restore expected functionality to the feed settings.
Upgrade Process
Users who update to the new version will need to re-authenticate with their Slack service. You do that by disconnecting and reconnecting.

Disconnect from Slack using the 「Disconnect」 button in the Slack Add-On Settings page.
Connect to Slack again using the normal process described here.

After that, functionality should continue to work as it previously did with no changes needed, except the Team Invite feature, as described below.
Team Invite Feature Deprecation
Previous versions of our Slack Add-On offered the Team Invite feature, which relied on a legacy API endpoint and the admin scope of a legacy API token.
Under the new Slack API and tokens, the endpoints offered for this feature are now only available to Slack Enterprise Grid accounts.
As of this update, this feature will no longer function within our Slack Add-On.

Fighting Spam

IntroductionSolutionsHoneypotCaptchaSubmit Button Conditional LogicMulti-Page FormsBlock Search IndexingPluginsField ValidationSpam BlockersBlock by IPCloudflareCode SnippetsField ValidationSpam Filter

Introduction

Spam is a problem which impacts all publicly accessible forms and fighting it is complicated by the fact that spammers and bots are constantly evolving their methods. The good news is there are a number of solutions you can use to reduce the amount of spam which is successfully submitted. But note that there』s not any single anti-spam method in the world able to catch 100% of spam, because of that you can find hundreds of different anti-spam techniques and services, therefore for better results we recommend using multiple solutions at the same time.

Solutions

Honeypot

Gravity Forms includes a built-in honeypot feature which can be enabled on the Form Settings page of each form. When enabled the form will include a field which is hidden from visitors but is visible to bots. If this field contains a value when the form is submitted the submission will be ignored; the entry is not saved, notifications, and add-ons are not processed.

The gform_honeypot_labels_pre_render filter can be used to change the labels used by the honeypot field.

If HTML5 is enabled on the Forms > Settings page the autocomplete='off' attribute will be added to the input, which should help prevent the input being filled by browsers.

Captcha

Our reCAPTCHA Add-On adds Google reCAPTCHA v3 functionality into your toolbox. Refer to documentation here.

The built-in Captcha field is another method to reduce spam from bots although it can introduce accessibility issues. This integrates Google』s reCAPTCHA version 2.

Submit Button Conditional Logic

Add a single line text field to your form which asks a simple question. A real person should be able to answer the question correctly whereas most bots won』t.

Here are some examples:

A panda is black and _____4 + 7 = _____What goes up, must come _____A cow has how many legs? _____

On the Form Settings page of the form you would enable button conditional logic based on this question field. If the submitter doesn』t input the correct answer the form can』t submit.

Multi-Page Forms

If you will be accepting payments using a card or payment add-on field position it on the last page of the form. Enabling the required setting on a number of fields located on earlier pages can help ensure the card/payment add-on field is only used by those who have successfully completed the earlier pages in the form, reducing the chances of your form being used for fraudulent carding activity.

Block Search Indexing

Preventing search engines from indexing the page containing the form can help prevent your form being targeted by bots and spammers.

Google recommends using the noindex directive but if the page is already indexed you』ll also need to remove it via webmaster tools.

Plugins

Gravity Forms includes built-in support for the Akismet Anti-Spam plugin by Automattic. We also have an Akismet Add-On which enhances the integration with form level settings to help improve the quality of the data sent to Akismet for evaluation.

The following add-ons are from certified developers:

Gravity Perks Blocklist by Gravity Wiz can be used to validate submissions against the WordPress Disallowed Comment Keys. Disallowed Comment Keys was previously known as Comment Blocklist (WordPress 5.4) and Comment Blacklist (WordPress 5.3 and earlier).Gravity Perks Limit Submissions by Gravity Wiz can be used to limit the number of entries that can be submitted by almost anything (user, role, IP, URL, field value) for almost any time period.Gravity Forms Zero Spam by GravityView uses JavaScript to append a custom input to the form; if the input is not found in the submission or value does not match the expected value the submission is marked as spam.

The following third-party plugins also offer integrations with Gravity Forms. Any listing here is not a recommendation or endorsement of fitness for any purpose.

Block IPs for Gravity Forms by Team Bright Vessel

Cloudflare

Cloudflare offers a number of services which can protect your site (and forms) such as IP Access Rules that would allow you to even block entire countries easily, DDoS Protection, WAF, Bot Management, Rate Limiting, SSL/TLS, and DNSSEC to name just a few.

Code Snippets

Code snippets can be used in the theme functions.php file or custom functionality plugins.

Field Validation

The gform_field_validation and/or gform_validation filters can be used to perform custom validation of field values.

Square Field

Pre-RequisitesAboutGeneral SettingsSub-LabelsAppearance SettingsField StyleSimplifiedTraditionalNotes

Pre-Requisites

This field is only available in the Form Editor if you have installed the official Gravity Forms Square Add-On

About

The Square field provides Credit Card and Cardholder input fields as provided by the Square payment service.

It can be found in the Pricing Fields section of the Field Chooser sidebar.

This field will add inputs for card details (card number, expiration date, CVC, and zip code) and Cardholder Name. Those fields are actually provided by Square and hosted on Square』s servers for end-to-end security of payment information.

General Settings

Sub-Labels

You can set a custom sub-labels for the available input fields by modifying these fields. What fields are available for this is dependent upon the Field Style you choose.

General settings for simplified and traditional layouts

Appearance Settings

Field Style

You can set the field style for the input fields by selecting Simplified or Traditional. This determines how the card detail inputs are organized. Changing the field style type will change the sub-label and placeholder options respectively.

Simplified

The Simplified style presents all inputs for card details (card number, expiration date, CVC, and zip code) on a single line.

With this layout, you can only set a placeholder for the Cardholder Name.

Traditional

The Traditional style presents each input for card details (card number, expiration date, CVC, and zip code) in its own delineated field.

This configuration allows you to add placeholders for each card detail field.

Notes

See also the article creating a Square compatible form.

Note that both Credit Card Details and Cardholder Name are required fields for the Square field:When using Page fields to create a multi-page form, the Square field should be located on the last page of the form.If you delete the Square field from your form, the Square feeds will automatically deactivate. This prevents them from running during form submission and generating a validation error due to missing Square fields.Your Gravity Forms Currency Settings must match the Currency Settings in your Square account.If you have another Payment Gateway add-ons installed and active, other card fields may be available. To allow users to choose from multiple payment processors, conditional logic can be used to show/hide the Credit Card field depending on the payment processor selection.

Introduction
Gravity Forms and Stripe allows you to quickly and easily implement credit card payments with WordPress. With the Stripe Add-On you can capture one time credit card payments or setup recurring payment subscriptions.
If you are familiar with our other Gravity Forms Add-Ons, or even if you』re not, you』ll be right at home getting started with the Stripe Add-On!
Pre-Requisites

Gravity Forms v2.4+
WordPress v3.8+
SSL Certificate Installed and Configured
Download and install the add-on
A Stripe account

Because of the secure nature of capturing credit card information, you will be required to purchase and install an SSL certificate on your web site if you have not already done so. You will also need to configure your WordPress site to work properly with SSL.
Contact your web host if you need assistance purchasing and configuring an SSL certificate.
If you need assistance configuring your WordPress site to work with SSL, we recommend the WordPress HTTPS (SSL) Plugin which you can find here: http://wordpress.org/extend/plugins/wordpress-https/
Setup Stripe
Learn how to setup the Stripe Add-On in our Setting Up the Stripe Add-On article.
Setup Your Form
Refer to the Setting Up a Stripe Compatible Form article for detailed instructions on how to setup your form to be compatible with the Stripe Add-On.
Setup Stripe Feeds
Now that you have configured the Stripe Add-On to work with your Stripe account, and you have a form configured and ready to interact with Stripe, it』s time to bring it all together by configuring the form to integrate with Stripe. Just like all of Gravity Forms Add-Ons, this integration is done by creating a feed.
Review our Creating a Feed for the Stripe Add-On article for step-by-step instructions.
Viewing Sales Results
After creating a feed and making your first sale, you can view the results on the Sales Results page.  Review Viewing Sales Results article for more information.
About Payment Collection Methods
The Stripe Add-On offers multiple methods to collect payment information. Each method offers a different split of responsibilities between your form and Stripe as pertains to the collection and storage of payment related information. See this help article for more information on the payment collection methods offered.
Stripe Subscription Cancellations
When setting up a Stripe Subscription, please keep in mind that the only way to currently cancel a subscription is via the WordPress Admin or the Stripe admin. You can cancel an existing subscription by viewing the entry associated with the subscription and choosing the cancel option for the Stripe subscription.
Stripe Add-On Hooks
The Stripe Add-On provides hooks that can be used to modify the default functionality or extend it. For more information, review the Stripe Add-On Hooks.
Add-On Framework Hooks
Because the Stripe Add-On is built using the Add-On Framework it also inherits any hooks available in the framework methods it uses such as:

gform_short_slug_field_value for changing a field value before it is passed to Stripe.

Initial release.

Upgrading to Stripe version 2.6

New FeaturesUpgrade NotesFurther Information

New Features
The Gravity Forms official Stripe add-on version 2.6 includes two new methods for collecting payment information:

Stripe Credit Card Field (Elements)
Stripe Payment Form (Checkout)

The two new methods for collecting information make the PCI compliance process easier, enhancing security because the credit card field (or the checkout form) are hosted by Stripe during the checkout process.
Upgrade Notes
When upgrading to Stripe v2.6 from a previous version, note that:

Previously created forms already using Stripe will continue to work and use the standard Gravity Forms Credit Card field.
Previously created forms already using Stripe will use the standard Gravity Forms Credit Card field even if you have chosen Stripe Payment Form (Stripe Checkout). To use the Stripe Payment Form (Stripe Checkout) Payment Collection Method instead, the Credit Card field will need to be removed from the form.
Previously created forms already using Stripe will use the standard Gravity Forms Credit Card field even if you have chosen Stripe Credit Card Field (Elements). To use Stripe Credit Card Field (Elements) instead, the Credit Card field will need to be removed from the form and the Stripe Card field added.
