Hi, I’m newbie in this forum. I just try to answer problem on morray extension “cannot redeclare loop()”, but I can’t leave a comment there (http://www.yiiframework.com/extension/morray/). So, I post it here.
When I use morray extension with more than one model that using morray behaviors, the system raise error "cannot redeclare loop()".
I have solve that error by fixing the code on MorrayBehavior.php, to place [font="Courier New"]function loop($obj, $options = array(), $arr = array())[/font] outside [font="Courier New"]public function toArray($options=array())[/font]. Here is my complete MorrayBehavior.php file:
<?php
/**
* MorrayBehavior (Model to Array Behavior)
*
* ver 1.0 beta
*
* Converts an AR model to an array, retaining associated relations.
*
**/
class MorrayBehavior extends CBehavior
{
public function toArray($options=array())
{
//option 'scenario', use a scenario to only display safe attributes
//default: empty (no scenario)
if (!isset($options['scenario'])) {
$options['scenario'] = "";
}
//option 'relname', key name of the array holding the relations
// use empty string to use no new array for relations
//default: "_rel"
if (!isset($options['relname'])) {
$options['relname'] = "_rel";
}
//get the owner class
$owner = $this->getOwner();
//check if the owner class is an AR class
if (is_subclass_of($owner, 'CActiveRecord')) {
//return the result by calling the recursive function
return $this->loop($owner, $options);
}
return false;
}
//this function recursively loops all attributes and relations of a supplied object
function loop($obj, $options = array(), $arr = array())
{
//store current object attribute values
$attributes = $obj->attributes;
//check if user supplied a scenario, and if this object has any rules
if ((!empty($options['scenario'])) && (is_array($obj->rules()))) {
//loop the rules, search for a matching scenario
foreach ($obj->rules() as $rule) {
//check if this scenario name matches the supplied one
if ((isset($rule['on']) && ($rule['on'] == $options['scenario']))) {
//check if this is the 'safe' option
if ((isset($rule[1])) && ($rule[1] == "safe")) {
//put the safe attributes in an array
$safe_attributes = explode(",", $rule[0]);
//new array for putting only the values of the safe attributes
$attributes_values = array();
//loop the safe attributes
foreach ($safe_attributes as $safe_attribute) {
//trim in case there are any spaces
$safe_attribute = trim($safe_attribute);
//if this safe attribute contains a value, save it in the new attribute array
if (isset($attributes[$safe_attribute])) {
$attributes_values[$safe_attribute] = $attributes[$safe_attribute];
}
}
//assign the safe attributes over the the array containing all the attributes
$attributes = $attributes_values;
}
}
}
}
// assign the attributes of current relation to array
$arr = $attributes;
//get relations from current relation
$relations = $obj->relations();
//put the keys (relation names) in an array
if ($relation_ids = array_keys($relations)) {
//loop relations
foreach ($relation_ids as $relation_id) {
//check if sub relation is loaded (using scopes or 'with')
if ($obj->hasRelated($relation_id)) {
$relation = $obj->{$relation_id};
//if sub relation is an object, there is 1 relation being returned
if (is_object($relation)) {
//if relname is supplied, use that to store the relation in
if (!empty($options['relname'])) {
$arr[$options['relname']][$relation_id] = loop($relation, $options, $arr);
}
else {
//if no relname is supplied, store directly in current array
$arr[$relation_id] = loop($relation, $options, $arr);
}
}
//if sub relation is an array, there are multiple relations being returned
if (is_array($relation)) {
//do a foreach on each sub relation
foreach ($relation as $sub_relation) {
//if relname is supplied, use that to store the relation in
if (!empty($options['relname'])) {
$arr[$options['relname']][$relation_id][] = loop($sub_relation, $options, $arr);
}
