Passing Arrays

[adnanhb]

Hi,

I am trying to pass an array from one page to another by using the hidden component of the HTML form. Following is the code:
print "<input type=hidden name=\"quantities[]\" value=\"$quantity[]\">";
This statement is giving an error. I have tried various variations but none are working. Some of the changes i made are:

print "<input type=hidden name=\"quantities[]\" value=\"$quantity\">";

print "<input type=hidden name=\"quantities\" value=\"$quantity">";

Any insight would be greatly appreciated.

You can't pass an array in this fashion.

I suggest that you do something like this:

<?php
print '<input type="hidden" name="array" value="'
. implode("|", $array) . '">'";
?>

Then you can use explode() to get the array back in your called script. This will only work for single dimension arrays, and only work if you implode() it with a character that doesn't appear in any of your array values.

<form stuff>
<input type=hidden name="quantity[0]" value="val0">
<input type=hidden name="quantity[1]" value="val1">
<input type=hidden name="quantity[2]" value="val2">
<input type=submit>

// page 2 //
if($_POST['quantity'])
 print_r($_POST['quantity'];
}

that should work
