Once you have created a payment form in WP SmartPay, you embed it on any WordPress page or post using a shortcode or a dedicated Gutenberg block. This guide covers both methods.

Finding the Shortcode

Go to SmartPay → Forms. In the forms list, each row has a Shortcode column showing the form's embed code in the format [sp_form id="123"].

Click the shortcode to copy it to your clipboard.

Method 1 — Gutenberg Shortcode Block

  1. Open the page or post you want to embed the form on.
  2. In the Gutenberg block editor, click the + button to add a block.
  3. Search for Shortcode and select it.
  4. Paste the shortcode (e.g. [sp_form id="42"]) into the block.
  5. Click Update or Publish.
Note: The Shortcode block does not render a preview in the editor — it shows the raw shortcode text. Visit the published page to see the form.

Method 2 — WP SmartPay Form Block

  1. In the block editor, click the + button and search for SmartPay Form.
  2. Select the WP SmartPay Form block.
  3. In the block's dropdown, choose the form you want to embed.
  4. The editor shows a live preview of the form inside the block.
  5. Click Update or Publish.

The SmartPay Form block is the recommended method for Gutenberg sites — you get a visual preview and can select the form from a friendly dropdown instead of typing a shortcode.

Classic Editor (TinyMCE)

If you are using the Classic Editor plugin:

  1. Paste the shortcode directly into the post content area.
  2. Make sure you are in Text mode (not Visual mode) if the shortcode is not rendering.
  3. Click Update.

Full-Page Embed vs Inline Embed

You can embed the form anywhere on a page — in the middle of content, in a sidebar widget, or as the sole element on a dedicated page. SmartPay's checkout CSS adapts to the container width.

For a cleaner experience, many sites create a dedicated "Donate" or "Buy Now" page with only the form on it. This keeps the URL shareable and the layout uncluttered.

Legacy Shortcode

Older versions of WP SmartPay used [smartpay_form id="123"]. This shortcode still works but [sp_form id="123"] is the current standard. Both are equivalent.
