Posting Arrays

[wrgill999]

how can i post an array?

meaning, if i have a list of 20 items, and each item has an id number and i want to pass all of the id #'s as a single array depending upon which items are selected....

so if i have a list of 20 items. each item has a checkbox. if that checkbox is checked, i want the id for each of those items passed onto another script in the id() array.

then i can perform processes on all of the items picked etc.

?

thanks.

I'm not exactly sure what you mean, but you could do something like this:

while(list($key, $val) = each($HTTP_POST_VARS)) {

  if ($val) {
    $id[$key] = $val;
  }

}

Another possibility would be:

foreach($HTTP_POST_VARS as $key => $val) {
  if ($val) {
    $id[$key] = $val;
  }
}

Hope that helps...

I was able to do a check box inside a form like this:

echo "input type=checkbox name=ship_no[] value=$SHIP_NUMBER";

This loads an array $ship_no[] with the checked values for $SHIP_NUMBER. Then submit the form. On the target page, I extracted the data from the array with the list function and used the foreach function to iterate through the array like this:

while (list ($array_key, $ship_number) = each ($ship_no))
foreach ($ship_no as $ship_number) {
\do whatever with your variable $ship_number
}

To pass the array $ship_no[] to another script without a form, you could serialize the array, url-encode it , pass it with a header as a string

//passing arrays to another page is tough.. it was giving me problems here, so I'm going to send a string instead
$ship_serial = serialize($ship_no);
$ship_serial = urlencode($ship_serial);
header("Location:/ship/pdf_monuments.php?ship_serial=$ship_serial");

And here is what I did on the target page to put the array back togather.

//ok.. in the previous page we serialized and urlencoded so we could pass an array value .. now we unserialize and stip slashes
$ship_serial=stripslashes($ship_serial);
$ship_serial = unserialize($ship_serial);
$ship_no=$ship_serial;

This again yields an array $ship_no[].

Hope this helps!
