修改Model.class.php中的create方法，我是在最后用了自己自定义的一个_after_create方法
/**
* 创建数据对象 但不保存到数据库
* @access public
* @param mixed $data 创建数据
* @param string $type 状态
* @return mixed
*/
public function create($data='',$type='') {
$odata = $data;
$olink = $this->options['link'];
// 如果没有传值默认取POST数据
if(empty($data)) {
$data = I('post.');
}elseif(is_object($data)){
$data = get_object_vars($data);
}
// 验证数据
if(empty($data) || !is_array($data)) {
$this->error = L('_DATA_TYPE_INVALID_');
return false;
}
// 状态
$type = $type?$type:(!empty($data[$this->getPk()])?self::MODEL_UPDATE:self::MODEL_INSERT);
// 检查字段映射
if(!empty($this->_map)) {
foreach ($this->_map as $key=>$val){
if(isset($data[$key])) {
$data[$val] = $data[$key];
unset($data[$key]);
}
}
}
// 检测提交字段的合法性
if(isset($this->options['field'])) { // $this->field('field1,field2...')->create()
$fields = $this->options['field'];
unset($this->options['field']);
}elseif($type == self::MODEL_INSERT && isset($this->insertFields)) {
$fields = $this->insertFields;
}elseif($type == self::MODEL_UPDATE && isset($this->updateFields)) {
$fields = $this->updateFields;
}
if(isset($fields)) {
if(is_string($fields)) {
$fields = explode(',',$fields);
}
// 判断令牌验证字段
if(C('TOKEN_ON')) $fields[] = C('TOKEN_NAME');
foreach ($data as $key=>$val){
if(!in_array($key,$fields)) {
unset($data[$key]);
}
}
}
// 数据自动验证
if(!$this->autoValidation($data,$type)) return false;
// 表单令牌验证
if(!$this->autoCheckToken($data)) {
$this->error = L('_TOKEN_ERROR_');
return false;
}
// 验证完成生成数据对象
if($this->autoCheckFields) { // 开启字段检测 则过滤非法字段数据
$fields = $this->getDbFields();
foreach ($data as $key=>$val){
if(!in_array($key,$fields)) {
unset($data[$key]);
}elseif(MAGIC_QUOTES_GPC && is_string($val)){
$data[$key] = stripslashes($val);
}
}
}
// 创建完成对数据进行自动处理
$this->autoOperation($data,$type);
// 赋值当前数据对象
$this->data = $data;
if($olink){
$this->options['link'] = $olink;
if(!$this->_after_create($odata)) return false;
}
// 返回创建的数据以供其他调用
return $data;
}然后在RelationModel.class.php中添加两个方法，一个是_after_create一个是opcreate protected function _after_create($data) {
// 关联更新
if(!empty($options['link'])){
return $this->opCreate($data);
}
return true;
}protected function opCreate($data,$name=''){
$result = false;
if(empty($data) && !empty($this->data)){
$data = $this->data;
}elseif(!is_array($data)){
// 数据无效返回
return false;
}
if(!empty($this->_link)) {
// 遍历关联定义
foreach($this->_link as $key=>$val) {
// 操作制定关联类型
$mappingName = $val['mapping_name']?$val['mapping_name']:$key; // 映射名称
if(empty($name) || true === $name || $mappingName == $name || (is_array($name) && in_array($mappingName,$name)) ) {
// 操作制定的关联
$mappingType = !empty($val['mapping_type'])?$val['mapping_type']:$val; // 关联类型
$mappingClass = !empty($val['class_name'])?$val['class_name']:$key; // 关联类名
$mappingKey =!empty($val['mapping_key'])? $val['mapping_key'] : $this->getPk(); // 关联键名
// 当前数据对象主键值
$pk = $data[$mappingKey];
if(strtoupper($mappingClass)==strtoupper($this->name)) {
// 自引用关联 获取父键名
$mappingFk = !empty($val['parent_key'])? $val['parent_key'] : 'parent_id';
}else{
$mappingFk = !empty($val['foreign_key'])?$val['foreign_key']:strtolower($this->name).'_id'; // 关联外键
}
if(!empty($val['condition'])) {
$mappingCondition = $val['condition'];
}else{
$mappingCondition = array();
$mappingCondition[$mappingFk] = $pk;
}
// 获取关联model对象
$model = D($mappingClass);
$mappingData = isset($data[$mappingName])?$data[$mappingName]:false;
if(!empty($mappingData) || $opType == 'DEL') {
switch($mappingType) {
case self::HAS_ONE:
$mappingData[$mappingFk] = $pk;
$result = $model->create($mappingData);
if($model->getError()) {
$this->error = $model->getError();
return false;
}
break;
case self::BELONGS_TO:
break;
case self::HAS_MANY:
foreach ($mappingData as $val){
$val[$mappingFk] = $pk;
$result = $model->create($val);
if($model->getError()) {
$this->error = $model->getError();
return false;
}
}
break;
case self::MANY_TO_MANY:
break;
}
if (!empty($val['relation_deep'])){
$model->opRelation($opType,$mappingData,$val['relation_deep']);
}
}
}
}
}
return $result;
}如何应用的呢？和原来一样，先create然后add就行了
有任何问题，请大家指正哈O(∩_∩)O
最佳答案
