如何通过隐藏字段传递数组

Question

here my code

$order[$j][0]="Euclidean Geomethiyil Kodpagugal";
$order[$j][1]=$q16;
$j++;

hidden field-

<input type="hidden" name="hdnTotal" value="<?php echo $gtot; ?>">
<input type="hidden" name="hdnOrder" value="<?php echo $order; ?>">
<input type="submit" value="Place Order">

hdnTotal value is coming in next page but hdnOrder is not. print($_POST['hdnOrder']) print only Array on screen.

Answer 1

Try json_encode:

<input type="hidden" name="hdnTotal" value="<?php echo htmlspecialchars(json_encode($gtot)); ?>">
<input type="hidden" name="hdnOrder" value="<?php echo htmlspecialchars(json_encode($order)); ?>">
<input type="submit" value="Place Order">

and for get it back, json_decode:

print(json_decode($_POST['hdnOrder']));

The bonus of this solution is that you will able to manipulate your array at client side easily with JavaScript.

But why do you want to do that ?

If it is not for manipulate your data at client side, you create an an unnecessary round trip of your data, that you can easily keep at server side with PHP sessions.
