Why is my PHP script sending blank emails?_问答_开发者

When I render it on the server side after uploading, I get an email but it is blank. The From is blank the text is blank the part in ECHO where $name is comes out blank. Any ideas what I can do to make this work?

Here is my form:

<form action="survey.php" method="post" name="survey">
        <table>`enter code here`
        <tr><th colspan="2">Survey</th></tr>
        <tr><td>Name:</td><td align="center"><input type="text"
name="name" id="name" /></td></tr>

        <tr><td>When was your last visit</td><td
align="center"><select id="long" name="long">
        <option value="Select">Please Select</option>
    <option value="1-2 days">1-2 days ago</option>
    <option value="3-5 days">3-5 days ago</option>
    <option value="1-2 weeks">1-2 weeks ago</option>
    <option value="3-5 weeks">3-5 weeks ago</option>

    <option value="2 months">2 months</option>
    <option value="3+months">3+ months </option>
    <option value="Never">Never Visited</option>
    </select></td></tr>
    <tr>
    <td>Tell us about your experience?</td><td
align="center"><textarea cols="22" rows="5" id="experience"
name="experience"></textarea></td></tr>
    <tr><td>Will you come back
    to visit again?</td><td align="center"><input type="checkbox"
id="visit" name="visit" value="Yes" />Yes<input type="checkbox"
id="visit" name="visit" value="No" />No</td></tr>

    <tr><td colspan="2"><input type="submit" value="Submit" /><input
type="reset" value="Reset" /></td></tr>
    </table>
    </form>

And my PHP code

<?php 

/* subject and e-mail variables*/   

$emailSubject = $name;  
$webMaster = 'patrick@patrickspcrepair.com'; 

/* Gathering data Variables */  

$nameField = $_POST['name'];    
$selectField = $_POST['long'];
$commentsField = $_POST['experience'];
$visitField = $_POST['visit'];

$body = <<<EOD
  <br><hr><b开发者_C百科r>
  Name: $name<br>
  Date of last visit: $long<br>
  Expierence: $experience<br>
  Visit again: $visit<br>

EOD;

$headers = "From: $name\r\n";   
$headers .= "Content-type: text/html\r\n";  
$success = mail ($webMaster, $emailSubject, $body, $headers); 

/* Results rendered as HTML */
/* When changing the fields please leave the <<<EOD and the EOD;
If they are deleted this form will not work */  
$theResults = <<<EOD

?>

From is blank because you have written $headers = "From: $name\r\n"; and $name is not declared anywhere. Change this to $headers = "From: $nameField\r\n";.

The same can be said for references to $long (should be $selectField), $experience (should be $commentsField) and $visit (should be $visitField).

As for echo "$theResults";:

Why bother storing the HTML in a string to then echo it out? Just drop out of PHP mode and start outputting the HTML directly.
Why surround the variable $theResults in quotes? echo $theResults; is better, adding the quotes creates a new string in memory first, then echos it.

Your are echoing fields that you did not declare... try adding extract($_POST); to the begining of your code

How is your error reporting set? Does it print or go to a log? Echo phpinfo() to see. Your log will tell you a lot.

In the following line I noticed that you have a space between "mail" and "(". There should be no space.

$success = mail ($webMaster, $emailSubject, $body, $headers);

If you are watching your error log you will catch things like this that are easy to miss.
