Name Your Price for FluentCart

A WordPress plugin that adds flexible payment forms powered by FluentCart. Create "name your price", "pay what you want", donation forms, or simple payment buttons — no product setup required.

Drop a form anywhere on your site using a shortcode or Gutenberg block. Visitors pick a preset amount or type their own, then check out instantly through FluentCart. Items are created on-the-fly at checkout time, so you don't need to configure any products in FluentCart.

Features

• On-the-fly payments — no FluentCart product setup needed; items are created dynamically at checkout
• Preset amounts — configurable quick-pick buttons (e.g. $5, $10, $25, $50, $100)
• Custom amount input — optional free-text field for any amount
• Title & description — optional rich text header above the form (inline-editable in the block editor)
• Min/max validation — enforce amount boundaries on both client and server
• Currency-aware — automatically uses your FluentCart currency settings (symbol, position, decimal format, zero-decimal currencies)
• Subscription support — optional or required recurring billing (daily, weekly, monthly, quarterly, half-yearly, yearly)
• Transaction fee recovery — optional checkbox to let visitors cover payment processing fees
• Gutenberg block — fully interactive editor preview with inline RichText editing and all settings in the sidebar
• Shortcode — [fc_name_your_price] for use anywhere shortcodes work
• Instant checkout — redirects straight to FluentCart checkout, no cart page needed
• Extensible — filter hooks for defaults, presets, validation limits, and variation data

Use Cases

• Donations — let supporters choose their own amount with preset suggestions
• Pay what you want — flexible pricing for digital products, services, or content
• Simple payment buttons — disable custom input, set a single preset, and use it as a quick buy button
• Recurring donations — combine with subscription mode for monthly/yearly giving
• Tip jars — small preset amounts with fee recovery to maximize what you receive

Requirements

• WordPress 6.0+
• PHP 8.1+
• FluentCart plugin (listed as a required plugin dependency)

Installation

1. Download the latest fc-name-your-price-x.x.x.zip from the Releases page
2. In WordPress, go to Plugins → Add New → Upload Plugin and upload the zip
3. Activate the plugin
4. Make sure FluentCart is installed and activated

Usage

Gutenberg Block

Search for "Name Your Price" in the block inserter. The block provides:

• Inline editing — click the title or description directly in the editor to type
• Live preview — see exactly how the form will look with real currency formatting
• Sidebar panels — Form Settings, Transaction Fees, and Subscription Settings

Shortcode

Basic usage:

[fc_name_your_price]

With all available attributes:

[fc_name_your_price
  min="5"
  max="500"
  show_presets="yes"
  allow_custom="yes"
  preset_amounts="5,10,25,50,100"
  button_text="Pay {amount}"
  default_amount="25"
  product_title="Donation"
  form_title="Support Our Work"
  form_description="Every contribution makes a difference."
]

Examples

Simple payment button (fixed $25, no custom input):

[fc_name_your_price show_presets="no" allow_custom="no" default_amount="25" button_text="Pay $25"]

Donation form with title:

[fc_name_your_price form_title="Support Our Mission" form_description="Your donation helps us continue our work."]

Monthly subscription (required):

[fc_name_your_price subscription_mode="required" billing_interval="monthly"]

Optional subscription with fee recovery:

[fc_name_your_price subscription_mode="optional" billing_interval="yearly" cover_fees="optional"]

How It Works

The plugin creates a custom item on-the-fly at checkout time using FluentCart's Custom Product Selling API. No products need to exist in FluentCart — the form generates an instant checkout URL with the chosen amount, and the integration class validates and builds the line item server-side via the fluent_cart/cart/validate_custom_item filter.

This means you can use the plugin as a lightweight payment button or donation form without any FluentCart product configuration. Just drop the block or shortcode on any page.

Prices are passed to FluentCart in cents (e.g. $10.00 = 1000).
