Simple form submission to email information

I found a simple, free email contact form online. It doesn't do exactly what I want and I was hoping I could get some help from the experts. I would like to know a couple of things. First, I would like when the user clicks 'submit' that an email is sent to me with the filled in information. Currently, that doesn't happen; an email is sent to me upon form s开发者_开发百科ubmission only when my email address is entered into the 'email' field. I would also like to know how to add another variable to catch, say... 'job title'. I don't need to worry about captcha catching spam, and I'm not going to mess with anymore form validation than already exists in the script I found. Any help would be awesome, guys!

<?php
if(isset($_POST['email'])) {

    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "myemail@email.com";
    $email_subject = "KARRN poster";


    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }

    // validation expected data exists
    if(!isset($_POST['first_name']) ||
        !isset($_POST['last_name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['telephone']) ||
        !isset($_POST['comments'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');

You can add another field simply by adding it into the form (e.g. <input type="text" name="job-title" />).

You can retreive the value entered into that field in the PHP script with $_POST['job-title'].

The script should send an email to whatever email address is assigned to the $email_to variable.

---

See the line that says mail($email_to, $email_subject, $email_message, $headers);? You can duplicate that and hardcode your email address and that will ensure you always receive an email when someone submits the form. If you want to change the message contained within, simply create a new variable (say $email_message2 and pass that to the new call to mail()).

As for adding the job_title field, you just need to do something like this: $jobTitle = $_POST['job_title']. You can then append that variable to the email message. On the form you would add <input type="text" name="job_title" />. Look for other instances of $_POST['SOMETHING'] and make sure to add appropriate code for this new field (this is for validation).

---

If you want it to be able to submit without an email address you should stop requiring emails being sent with this line

if(isset($_POST['email']))

Note that you will have to set a blank value to $email_from later on, if $_POST['email ] wasn't set, so that you don't get a Notice from PHP on this line $email_from = $_POST['email']; // required

To add job title, just add an <input> on the form, and access it via post like the other posted variables. You can require it by adding it to the line that validates the other POSTs.

By the way, if your form is public I highly reccomend putting a captcha on it. Spammers aren't your only concern, you can also be email-bombed by a malicious person. This happened to me so I always recommend a captcha.
