Help with initializing/sending a contact form

Question

Hi guys.
Basically, I created a standard HTML webpage(s) in Dreamweaver (this form is on a HTML file, not a PHP file). I have a form in there (at the footer of all my webpages), and it looks like this:
  <div id="form">
            <form action="PHP/contact-send.php" id="contactForm" name="Form1" method="post"  >
                <fieldset>
                    <p>
                         <label for="name">Name</label>
                        <input id="name" type="text" value="Under construction" name="Name"/>
                    </p>
                    <p>
                        <label for="email">Email</label>
                        <input id="email" type="text" value="Under construction" name="Email"/>
                    </p>
                    <div class="cl"><!-- --></div>
                    <p>
                        <label for="message">Message</label>
                        <textarea id="message" cols="10" rows="10" name="message" ></textarea>
                    </p>
                    <p><input class="sumbit_button" type="submit" name="submit" value="" id="submit" /></p>
                </fieldset>
            </form>
          </div>
I have styled this form, and added Jquery validation to it which works fine.
All I want to do isinitialize this form to send e-mail (I uploaded my website, and the form does not work)... I have specified the path to the PHP (PHP/contact-send.php) in the form (and yes, I put the PHP file in my website's directory... lol), and yet the form does not work. Very frustrating... Especially after I have tried a lot of different PHP codes, and none of them work.. Can someone please help me with a simple PHP code that I can paste into my "contact-send.php" file and link to the form in the "index.html" file? Also, if possible
a popup message that shows when the form is successfully sent (not on a new page, just a simple Javascript alert).
I am using 000webhost, and a free domain (.co.cc).
Also, I would like to have a search bar on my website... that, too has been styled, I just want to know how I can code it to have it function and display results.
Thankyou for your help guys.

Answer 1

I suppose this means I can have the form working on a HTML file and simply link it to the file containing the PHP code in the "form action"?  
In other words, I don't need to have my form design on a PHP file for it to work?
Correct. 
<form action="path/form-processing-script.php"
Also, I'd rather not have the user be redirected to a new page when the form is sent. Can I simply use an alert popup message? (i.e. "your message has been sent, click OK to contine) 
Most scripts provide variables for either redirecting to a success.html page or displaying error & success messages in the script.
I don't favor client-side "alert boxes" because they won't display if JavaScript is disabled in browsers.
Also like I said before, I have already styled the form, and added validation... Do any of those links allow for me to simply use the PHP code (editing the necessary fields like "name" and "email") without having to use their validation as well?
Yes, you could use your current form providing all field names exactly match those in the script.
As above, client-side validation only works if JavaScript is enabled in browsers.
PHP (server-side) validation is much more reliable.
