Looking for Email Form script recommendations for PHP / Desktop+Mobile (with or without jQuery enhancements)

Not to seem ungrateful (because not even Dreamhost wants to waste their time on this one with me, as "this goes a little beyond the scope of support we provide") but I'm finding it difficult to stay focused on this thing's pace; which is probably why I tend to avoid video tutorials in general. Is there a text version of it somewhere with code I can just copy/paste, test-drive and deconstruct?

Under the video there is a 'show more' link. If you cick on that there is a download link to the code.

No. That shows an example of deploying PHPMailer using 'Composer',  a workflow where you would be using the terminal to set up the PHPMailer script but first you have to install 'Composer' on your machine....too much trouble in my opinion unless you're a nerdy type.  If you are going to use PHPMailer I suggest you download the zip file to which Nancy supplied a link to in post No. 3. However you still have work to do because PHPMailer alone contains no form validation apart from exiting the script if a non-valid email is supplied, which means the user gets delivered a blank page instead of a message saying the email is invalid. You need to code the validation of the form fields prior to handing the information being collected off to the PHPMailer script. Of course you can use the script without any validation but you risk getting spam.

The youtube video I posted a link to, which uses the php mail() function instead, includes validation of the email field and some sanitisation of the form fields to stop undesired characters being injected into the form fields. Of course html5 has its own email validation <input type="email"> which wont let the form be submitted unless a valid email is supplied, so you could use that if you only wanted to validate the email form field.

When I say valid email I mean any email that's formatted like an email, the email doesnt have to exist so its no protection against spam, you will more than likely need to introduce a form captcha or a question/answer form field BUT I would for now just concentrate on getting the basic form up and running as they can be introduced later.
