Question

I have a very large orderform, where customers can order different food.

Here is an example of my html (not completely sure if this is the correct way):

<legend>Dinner</legend>
<label for="beef">Beef</label>
<input type="text" id="beef" name="order[]dinner[][beef]" placeholder="How many beef plates do you want?">

<label for="chicken">Chicken</label>
<input type="text" id="chicken" name="order[]dinner[][chicken]" placeholder="How many chicken plates do you want?">


<legend>Desserts</legend>
<label for="cake">Cake</label>
<input type="text" id="cake" name="order[]desserts[][cake]" placeholder="How many cake slices do you want?">

<label for="pudding">Pudding</label>
<input type="text" id="pudding" name="order[]pudding[][cake]" placeholder="How many puddings do you want?">

How could I make a forloop to collect all the orders (where the value is over 0)

I have tried this code:

$order_array = $_POST['order'];

foreach ($order_array AS $key => $value){
    $order .= "<p><strong>$key:</strong> $value</p>\n";
}

But the output is this:

0: 30
1: 2

I would like it to be:

Beef: 30
Chicken: 1

Also, if possible could display the “category” like:

Dinner:
Beef: 30
Chicken: 1

Dessert:
Cake: 29
Pudding: 2

Edit:

Here is my post array:

array (
  'order' => 
    'Dinner' => 
    array (
      'beef' => '',
      'chicken' => '40',
    ),
    'Dessert' => 
    array (
      'Cake' => '',
      'Pudding' => '',
    ),
  ),

First, change your inputs so that their names are in the following format:

<input name="order[category][food]" />

Then, once the data has been posted you can do something like the following to get the desired output:

if (!empty($_POST['order'])) {

  foreach ($_POST['order'] as $type => $items) {
    echo '<strong>' . ucfirst($type) . '</strong><br />';

    foreach ($items as $name => $qty) {
      echo ucfirst($type) . ': ' . $qty . '<br />';
    }
    echo '<br />';
  }
}

Which would output something like the following:-

Dinner
Beef: 12
Chicken: 2

Dessert
Cake: 4
Pudding: 1

Edit: If you need to prevent displaying categories ($type) from showing if there are no $items in them, you can do the following:

if (count(array_filter($items))) {
  echo '<strong>' . ucfirst($type) . '</strong><br />';
}
