How to display name instead of 'Array' when displaying multidimensional array in form

Oct 25 '10, 04:27 AM

I'm having a problem receiving the full amount of information i need on a grocery order from that i'm accessing inputted values using form to mail in php.

a snippet of my form looks like this:

Code:

<html>
<body>
<form action="...php" method=POST...
<tr>
              <th scope="col">Beer:</th>
              <th scope="col"><input type="text" name="BeerandWine[Beer][]" /></th>
              <th scope="col"><input type="text" name="BeerandWine[Beer][]" /></th>
              <th scope="col"><input type="text" name="BeerandWine[Beer][]" /></th>
              </tr>
            <tr>
              <th scope="col">Wine:</th>
              <th scope="col"><input type="text" name="BeerandWine[Wine][]" /></th>
              <th scope="col"><input type="text" name="BeerandWine[Wine][]" /></th> 
              <th scope="col"><input type="text" name="BeerandWine[Wine][]" /></th>      
              </tr>
            <tr>
              <th scope="col">Liquor:</th>
              <th scope="col"><input type="text" name="BeerandWine[Liquor][]" /></th>
              <th scope="col"><input type="text" name="BeerandWine[Liquor][]" /></th>
              <th scope="col"><input type="text" name="BeerandWine[Liquor][]" /></th>
              </tr>
...</form>
</body>
</html>

There are many of these, it's a full grocery list.

here is my php code to send it to my email:

Code:

<?php
foreach($_POST as $key){
         if (is_array($key)){
         $message.="Category: $key\n";
            foreach($key as $row){
               $message.="Item: $row\n";
            foreach($row as $col => $val){
            $val = stripslashes($val);
                  $message.="$col: $val\n";
            }
         } 
       }
}
?>

And here is what shows up in my email:

Category: Array
Item: Array
0: Stella
1: 6 pack
2: Cold
Item: Array
0: Merlot
1: 750ml
2:
Item: Array
0: Whiskey
1:
2: With cup

I'ts really a very handy script, except i can't seem to gather anything but 'array' from $key and $row.
How can I make the index name of the nested array display in my email, instead of 'array'. Keeping in mind I have a few hundred inputs.

This is how i want it to look:

Category: BeerandWine
Item: Beer
0: Stella
1: 6 pack
2: Cold
Item: Wine
0: Merlot
1: 750ml
2:
Item: Liquor
0: Whiskey
1:
2: With cup

and i also want to have:
Type/Brand:, Quantity:, Notes:
instead of:
0:, 1:, 2:
and not display the empty values, but those I could probably find on my own after I solve this...I've been searching for a solution to this for days. Any help?

To print out an array you need print_r($array) .
I find formating is much tidier. Use

Code:

'<pre>Data '.print_r($array,1).'</pre>'

Note the '1' as second parameter in print_r.
You will still get the word 'array'. The only way I have found to remove this is with str_replace('Ar ray','',string)
