[fw-general] Re[fw-general] comendation to solve problem with ZendJsonExprFinder in Zend_Json::encode()

[mezoni]

The problem with UTF keys and diffirence with them before call json_encode
and after.
Code Example:

<?= $this->dialogContainer('dialogTest', '1',
    array(
        'modal' => true,
        'buttons' => array(
            'Отмена 3' => new Zend_Json_Expr('function(){ alert("Cancel 3");
$(this).dialog("close") }'),
            'Latin 2' => new Zend_Json_Expr('function(){ alert("Latin 2");
$(this).dialog("close") }'),
            'Добавить 1' => new Zend_Json_Expr('function(){ alert("Add 1");
$(this).dialog("close") }')
            )),
    array('title' => 'ZendJsonExprFinder Test Multilangual Dialog'))
?>

Code generated by current Zend_Json::encode() implementation:

<code>
<script type="text/javascript">
//<![CDATA[
$(document).ready(function() {
   
$("#dialogTest").dialog({"modal":true,"buttons":{"\u041e\u0442\u043c\u0435\u043d\u0430
3":"____\u041e\u0442\u043c\u0435\u043d\u0430 3_0","Latin 2":function(){
alert("Latin 2"); $(this).dialog("close")
},"\u0414\u043e\u0431\u0430\u0432\u0438\u0442\u044c
1":"____\u0414\u043e\u0431\u0430\u0432\u0438\u0442\u044c 1_2"}});
});
//]]>
</code>


These changes in code may partialy solve this problem:

public static function encode($valueToEncode, $cycleCheck = false, $options
= array())
{
        // ... here is not changed code

        //only do post-proccessing to revert back the Zend_Json_Expr if any.
        if(count($javascriptExpressions) > 0) {
            for($i = 0; $i < count($javascriptExpressions); $i++) {
                $key        = $javascriptExpressions[$i]['key'];
                $value      = $javascriptExpressions[$i]['value'];
                $magicKey   = $javascriptExpressions[$i]['magicKey'];
                $magicValue = $javascriptExpressions[$i]['magicValue'];

                $encodedResult = str_replace(
                    '"'.$magicKey.'":"'.$magicValue.'"',
                    '"'.$key.'":'.$value,
                    $encodedResult
                );
            }
        }

         return $encodedResult;

}



private static function _recursiveJsonExprFinder(&$value, array
&$javascriptExpressions, &$currentKey=null)
    {
        if($value instanceof Zend_Json_Expr) {
            $count    = count($javascriptExpressions);
            $magicKey   = "____Zend_Json_Expression_Index_".($count);
            $magicValue = "____Zend_Json_Expression_Value_".($count);
            $javascriptExpressions[] = array(
                "key"        => $currentKey,
                "value"      => $value->__toString(),
                "magicKey"   => $magicKey,
                "magicValue" => $magicValue
            );
            $value      = $magicValue;
            $currentKey = $magicKey;
        } elseif(is_array($value)) {
            $keys = array_keys($value);
            $value2 = array();
            foreach($keys AS $k1) {
                $k2 = $k1;
                $value2[$k2] = self::_recursiveJsonExprFinder($value[$k1],
$javascriptExpressions, $k2);
            }
            $value = $value2;
        } elseif(is_object($value)) {
            foreach($value AS $k => $v) {
                $value->$k = self::_recursiveJsonExprFinder($value->$k,
$javascriptExpressions, $k);
            }
        }
        return $value;
    }


And generated code:

<code>
<script type="text/javascript">
//<![CDATA[
$(document).ready(function() {
    $("#dialogTest").dialog({"modal":true,"buttons":{"Отмена 3":function(){
alert("Cancel 3"); $(this).dialog("close") },"Latin 2":function(){
alert("Latin 2"); $(this).dialog("close") },"Добавить 1":function(){
alert("Add 1"); $(this).dialog("close") }}});
});
//]]>
