How to Launch Overlay from Other Buttons or Links

This article details adding custom code to your WordPress site and is intended for developers. Although we don’t provide custom development services ourselves, if you need help we highly recommend Codeable.

Custom code snippets are provided as-is and there is no guarantee they will continue to work across multiple versions of WP Simple Pay.

Step 1: Update the Button URL

To launch a Stripe Checkout or overlay payment form via a custom button link you need to change the button link URL. Adjusting the URL of the button link will depend on how you are editing your content. Update the URL to the following:

#form-176

Replace 176 with the ID of the payment form you would like to launch. You can find the ID of your payment form in the form edit screen. The form ID is the number portion of the Simple Pay shortcode as shown below.

Next, embed the WP Simple Pay payment form shortcode in your page as you would normally: . This will cause the payment form to output on the page, but we will hide it in the next steps to ensure only the custom button link is visible.

Step 2: Add Custom JavaScript

There are many ways to add custom JavaScript code to your WordPress website. See our recommended guide for adding code snippets. We recommend that you add JavaScript to your theme’s footer using the free plugin WP Code. Go to Code Snippets β†’ Header & Footer, then and add your CSS to the Footer section as shown below.

launch overlay forms from buttons links add js
<script>
( function( $ ) {
// Update comma separated list with payment form ID(s) to launch.
var ids = [ '176' ];

// Do not modify.
ids.forEach( function( id ) { $( 'a[href~="#form-' + id + '"]' ).click( function( e ) { e.preventDefault(); $( '#simpay-' + id + '-payment-button' ).click(); $( '#simpay-modal-control-' + id ).click(); }); });
})( jQuery );
</script>

Replace the 176 in line 4 with the ID of your payment form. If you are creating multiple buttons on a page, you can add a comma separated list of payment form IDs you want to be able to launch.

Step 3: Add Custom CSS

There are many ways to add custom CSS code to your WordPress website. We have outlined a few ways in our documentation. We recommend that you add CSS to your theme’s header using the free plugin WP Code. Go to Code Snippets β†’ Header & Footer, then and add your CSS to the Header section as shown below.

launch overlay forms from buttons links add css
<style>
.simpay-form-wrap { display: none; } 
</style>

This will hide the default shortcode output so only the custom button link is visible.
