I’m looking for a clean JavaScript snippet that I can drop straight into the WPCode plugin to handle client-side validation on my WordPress forms. The check should fire the moment a visitor presses the Submit button—before anything is sent to the server—so users instantly see what needs fixing without a page reload, such as in this demo https://react.spruko.com/spruha-ts/preview/Forms/FormValidation/ My must-haves: • The site has a number of forms as outlined on the attachment doc. • Show clear inline messages and keep styling consistent with my theme. You will write your validation code on the WPCode plugin, not on the template files. There are already some code snippets. Immediate start required.
