Question

How can I pretty print into a div a json string assigned to smarty?

i know i can run php functions in smarty, so maybe a custom function will work?

thanks in advance.

The easiest thing to do is to convert the object to an associative array, and then parse it. The function would look like this:

function format_json($array, $indent) {

    $indent_text = '';

    for ($ii = 0;$ii < $indent; $ii++)
        $indent_text .= '    ';

    echo '<br />'.$indent_text.'{<br />';

    foreach ($array as $key => $value) {
        echo $indent_text.'"'.$key.'" : '; 
        if (is_array($value))
            format_json( $value, $indent + 1 );
        else echo '"'.$value.'"; <br />';
    }
    echo $indent_text.'}<br />';
}

<pre><code><?php format_json(json_decode($your_json_object, true), 0); ?></code></pre>

Obviously, you can style the tag and change the indentation any way you want.
