动态添加输入字段的PHP表单处理

Question

I am having trouble with the PHP form handling for dynamically added input fields.

The JavaScript and HTML code I am testing with can be found at http://jsfiddle.net/wd5y9/ . This part, obviously, works like a charm.

Here is my PHP code -

$emailSubject = 'Test Form';
$mailto = 'xxx@xxx.com';

$project = $_POST['project'];
$department = $_POST['department'];
$task = $_POST['task'];
$hours = $_POST['hours'];
$comment = $_POST['comment'];

date_default_timezone_set('America/Chicago');
$date = date('l F j, Y g:ia T');

$body = <<<EOD

<h2>Form Information</h2>
<table>
<tr>
<td><strong>Project</strong>: $project<br /></td>
<td><strong>Department</strong>: $department<br /></td>
<td><strong>Task</strong>: $task<br /></td>
<td><strong>Hours</strong>: $hours<br /></td>
<td><strong>Comment</strong>: $comment<br /></td>
</tr>
</table>

<p>Form submitted $date.</p>

EOD;

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

Here is how the e-mail came through after testing -

Form Information Project: Array Department: Array Task: Array Hours: Array Comment: Array

So what am I doing wrong? Thanks!

Answer 1

You probably have arrays posted. So you need to do something like

$project = $_POST['project']['somethingHere'];

If you post a print_r of your $_POST ( print_r($_POST) ) we will be able to help you even more.

EDIT

From your comment I see that you have two projects, departments, comments etc.

So in order for your code to work it should be a loop.

for($i=0; $i<=count($_POST['project']); $i++)
{
 <h2>Form Information</h2>
<table>
<tr>
<td><strong>Project</strong>: $project[$i]<br /></td>
<td><strong>Department</strong>: $department[$i]<br /></td>
<td><strong>Task</strong>: $task[$i]<br /></td>
<td><strong>Hours</strong>: $hours[$i]<br /></td>
<td><strong>Comment</strong>: $comment[$i]<br /></td>
</tr>
</table>
}

Answer 2

You have multiple rows (assuming they generate them) posting to your server with the same name, so the values are actually arrays of those values.

So to access the first project, you'd just access the first value of the $project array:

$project = $_POST['project'];
$firstProject = $project[0];

Or better yet, just loop over them all to spit out all rows in your email, something like this:

foreach ($project as $i => $thisProject) {
?>

<h2>Form Information</h2>
<table>
<tr>
<td><strong>Project</strong>: $project[$i]<br /></td>
<td><strong>Department</strong>: $department[$i]<br /></td>
<td><strong>Task</strong>: $task[$i]<br /></td>
<td><strong>Hours</strong>: $hours[$i]<br /></td>
<td><strong>Comment</strong>: $comment[$i]<br /></td>
</tr>
</table>
