Iterate PHP Array in Form Submission - php

Question

I have an HTML form that's submitting to a PHP script and send it as an email.
The problem I'm having is iterating the array and getting the output formatted into a table correctly.
My input fields look like this:
<input class="form-control" type="text" name="alternate[][qty]" />
<input class="form-control" type="text" name="alternate[][height]" />
I am iterating the array like this:
if ( isset( $_POST['alternate']))
{
foreach($_POST['alternate'] as $alt)
{
$message .= "<tr><td>" . $alt['qty'] . "</td><td>" . $alt['height'] . "</td></tr>";
}
}
I'm getting the correct values from the array but they are not formatted correctly. I am looking for an output something like this:
123 45
but instead it breaks across two rows like this:
How can I get both values on the same line?
EDIT:
Using
echo '<pre>';
print_r($_POST['alternate']);
echo '</pre>';
I get
Array
(
[0] => Array
(
[qty] => 54
)
[1] => Array
(
[height] => 5
)
[2] => Array
(
[qty] => 34
)
[3] => Array
(
[height] => 5
)
[4] => Array
(
[qty] => 36
)
[5] => Array
(
[height] => 45
)
...
)
which makes it look like I actually have 6 arrays...? That would explain why I'm getting each cell on a separate row, but I still don't understand how to fix it...

Answer 1

You're iterating through every element in $_POST['alternate'] and creating a row for each iteration. There are two elements, thus two rows.
There's no need to iterate since you already know which elements you'll get:
if ( isset( $_POST['alternate']))
{
$message = "<tr><td>{$_POST['alternate']['qty']}</td><td>{$_POST['alternate']['height']}</td></tr>";
}

Give this a shot, I hope that's what you're opting for.
if(isset($_POST['alternate']))
{
$message = "<tr>";
foreach($_POST['alternate'] as $alt)
{
if(isset($alt['qty']))
$message .= "<td>" . $alt['qty'] . "</td>";
elseif(isset($alt['height']))
$message .= "<td>" . $alt['height'] . "</td>";
}
$message .= "</tr>";
}
This gave me <tr><td>123</td><td>45</td></tr>.
EDITED SOLUTION
This script actually takes care of <tr> tags inside of the loop.
if(isset($_POST['alternate']))
{
foreach($_POST['alternate'] as $alt)
{
if(isset($alt['qty']))
$message .= "<tr><td>" . $alt['qty'] . "</td>";
elseif(isset($alt['height']))
$message .= "<td>" . $alt['height'] . "</td></tr>";
}
}
Try it out and let me know.

Your HTML actually declares separate array entries. You need to group them by defining keys for the array. Something like:
<input class="form-control" type="text" name="alternate[0][qty]" />
<input class="form-control" type="text" name="alternate[0][height]" />
Then the next group of fields uses "1" and so on.
