Hello @JessicaH,
Certainly, however, the mobile UI does not provide for uploading images to the post for me.
My current setup is an HTML form that posts to a PHP handler. There are fields in the form that are required. For example you must have a comment with at least 10 characters, you must provide email, etc. Upon submit the form is processed for validation errors, an array of errors is created, and if the array has length the email is not sent and errors are displayed to the user describing what needs to be corrected in order to successfully send the email.
HubSpot creates contacts from my form. When someone, or a bot, attempts to send an invalid form, a contact is created in my CRM. I would have expected that a contact would not be created until email successfully sent.
In lieu of a screenshot, you can see the form at https://www.resoiso.com/#contact
If you submit an invalid form you will still creat a contact in HubSpot.
Disabling submit until form validation may be an option, but this is a common UX design to help prevent spam and help legitimate users complete the form correctly.
Thank you for your response,
Doug
