Passing an array using an HTML form hidden element

Question

I am trying to post an array in a hidden field and want to retrieve that array after submitting a form in PHP.

$postvalue = array(\"a\", \"b\", \"c\");


        

Answer 1

Use:

$postvalue = array("a", "b", "c");
foreach($postvalue as $value)
{
    echo '<input type="hidden" name="result[]" value="'. $value. '">';
}

And you will get $_POST['result'] as an array.

print_r($_POST['result']);

Answer 2

You can use serialize and base64_encode from the client side. After that, then use unserialize and base64_decode on the server side.

Like:

On the client side, use:

    $postvalue = array("a", "b", "c");
    $postvalue = base64_encode(serialize($array));

   // Your form hidden input
   <input type="hidden" name="result" value="<?php echo $postvalue; ?>">

On the server side, use:

    $postvalue = unserialize(base64_decode($_POST['result']));
    print_r($postvalue) // Your desired array data will be printed here
