This template can easily accommodate various screen sizes, making it versatile for different devices.

With a clean, modern aesthetic, the flat template eliminates shadows and textures to focus on simplicity and minimalism.

It’s suitable for businesses that aim for a sleek, contemporary look that aligns with a flat design digital branding strategy.

The properties for input fields on the Payment Form could be applied for the following states:

  • not-empty
  • error
  • valid
  • defaul - without specifying the state

In case the state is not specified, properties are applied for all states.

The following pseudo-classes and pseudo-elements can also be styled using a nested object inside a variant:

  • :hover
  • :focus
  • :placeholder

There is no support for transferring images - neither via link or via data-uri.

For the Solidgate Payment Form, applying CSS styles enables control over form elements’ visibility, providing control over specific properties’ display within the form.

Please note that hiding price-related fields on the payment form might impact the form’s functionality, so thorough testing is recommended to ensure the form still functions correctly.

}

Label and placeholder customization

To customize all labels on the payment form, add the parameter fieldNameLabel with the new label name in the formParams object for each desired field. To customize all placeholders on the payment form, add the parameter fieldNamePlaceholder with the new label name in the formParams object for each desired field.

cardExpiryDateLabel
cardCvvLabel
cardNumberLabel
cardHolderLabel
cardExpiryDatePlaceholder
cardCvvPlaceholder
cardNumberPlaceholder
cardHolderPlaceholder

To get the value of fieldNameLabel or fieldNamePlaceholder for additional fields, you need to take the Field Class name on the table, remake it into camelcase, and add a Label or Placeholder at the end.

For example, bolivia_ci becomes boliviaCiLabel, and argentina_dni becomes argentinaDniLabel

    argentinaDniLabel: 'DNI',
    boliviaCiLabel: 'CI'
  }
})

Custom submission

The Solidgate Payment Form provides two options for payment submission:

  • click on the payment button
  • use the form.submit method
The option to display a custom payment button below the form is available, allowing for the collection of additional user data.

To hide the payment form submit button, set the allowSubmit display property in formParams to false during initialization. This action not only hides the button but also blocks form submission via the enter key.

Actual submission does not occur if:

  • Additional fields require display: Users will encounter a validation error for the new field.
  • Some fields await validation: Users will see validation errors on the form.
  • Validation errors exist in form fields: These must be resolved before the form can be submitted.

Otherwise, the form will be submitted.
