您好我的代码是没有事务执行但是事务没有运行。我的DB Class封装了我在BaseApp Class中编写的预准备语句，而BaseTransactApp Class又扩展了这些语句。
BasetransactApp Class由EqRqst Class扩展。 EqRqst Class由EqLeaseRequest Class扩展，2SQLSTATE[HY000]: General error用于使用有问题的代码调用特征中的代码。
有一次它显示错误$this->_pdo->setAttribute( PDO::ATTR_EMULATE_PREPARES , false);
当我没有设置
DB Class我的 <?php
class DB{
`enter code here` private static $_instance = null;
private $_pdo,
$_query,
$_error = false,
$_results,
$x,
$_count = 0;
private function __construct(){
try{
$this->_pdo = new PDO('mysql:host=' .Config::get('mysql/host') . ';dbname=' . Config::get('mysql/db'), Config::get('mysql/username'), Config::get('mysql/password'));
$this->_pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$this->_pdo->setAttribute( PDO::ATTR_EMULATE_PREPARES , false);
}catch(PDOException $e){
die($e->getMessage());
}
}
public static function getInstance(){
if(!isset(self::$_instance)){
self::$_instance = new DB();
}
return self::$_instance;
}
public function query($sql, $params = array()){
$this->_error = false;
if($this->_query = $this->_pdo->prepare($sql)){
$x = 1;
if(count($params)){
foreach($params as $param){
$this->_query->bindValue($x,$param);
$x++;
}
}
if($this->_query->execute()){

return $this;

是
BaseApp Class IT由 protected $db,
$data,
$table;
public function __construct(){
$this->db = DB::getInstance();
}
public function getProp($prop){
return $this->$_prop;
}
public function setProp($objVar,$val){
$this->objVar = $val;
}
public function create($fields = array()){
if(!$this->db->insert($this->table, $fields) ){
throw new Exception('There was a problem creating an account.');
}
}
public function get($where = array()){
$dbResult = $this->db->get($this->table, $where);
if($dbResult->count()){
$this->data = $dbResult->first();
return true;
}
return false;
}
public function update($fields = array(),$id = null){
if(!$this->db->update($this->table,$id,$fields)){
throw new Exception('There was a problem Updating');
}
}
public function delete($where = array()){
$this->db->delete($this->table,$where);
}
public function data(){
return $this->data;
}
public function getTable(){
return $this->table;
}
public function getLastInsertId(){
return $this->db->getLastId();
}
}
?>
组成
public function __construct(){
parent::__construct();
if($this->db){
echo 'WWWWWWWWWWWWWWWW';
}
}
public function beginTransaction(){
return $this->db->beginTransaction();
}
public function commit(){
return $this->db->commit();
}
public function rollBack(){
return $this->db->rollBack();
}
}
?>
由...延长
protected $EqRqst_ID,
$DateOfRequest,
$rqstState,
$RequestedPackage = array(),
$state_ID,
$table = 'EqRqst';
public function __construct(RqstState $state){
parent::__construct();
$this->rqstState = $state;
}
public function create($args = array()){
BaseTransactApp::create($args);
// $this->EqRqst_ID = $this->getLastInsertId();
// echo $this->EqRqst_ID;
}
public function getRqstID(){
return $this->EqRqst_ID;
}
public abstract function makeRequest($requestArg = array(),$elRqst = array(),$rqstPakg = array());
}
?>
然后
public function makeRequest($requestArg = array(),$eqLsRqst = array(),$rqstPakg = array()){
try{
$this->beginTransaction();
parent::create($requestArg);
$this->EqRqst_ID = parent::getLastInsertId();
$this->create($eqLsRqst);
$this->_RequestPkg->create(multi_array_merge(array('EqRqst_ID'=> $this->EqRqst_ID),$rqstPakg));
$this->commit();
}catch(Exception $e){
$this->rollBack();
echo $e->getMessage().;
}
//$this->EqRqst_ID = $this->getRqstID();
}
此特征包含eqleaserequest使用的代码。此代码在没有事务的情况下执行良好但无法使用它们执行此操作
use traitRequest;
//protected $table = 'EqLeaseRequest';
private $_Emp,
$_Emp_ID,
$_RequestPkg,
$_Intended_Use,
$_EqRqst,
$_EqRqst_ID,
$_Expected_Returndate;
public $rqstID;
public function __construct(RqstState $state,Employee $Emp,RequestPackage $RqstPkg){
parent::__construct($state);
$this->_Emp = $Emp;
$this->_RequestPkg = $RqstPkg;
}
public function create($eqLsRqstArg = array()){
$this->table = 'EqLeaseRequest';
print_r(array_merge(array('EqRqst_ID'=> $this->EqRqst_ID),$eqLsRqstArg));
BaseTransactApp::create(array_merge(array('EqRqst_ID'=>$this->EqRqst_ID),$eqLsRqstArg));
//BaseTransactApp::create($eqLsRqstArg);
}
}
}
?>
此代码是我在注释掉事务代码时运行的问题，但没有使用它。 <执行
此类是使用TraitRequest的类
{{1}}
答案 0 :(得分：-1)
我能够通过更改Trait traitRequest中的代码找到解决方案。
解决方案如下
trait traitRequest { public function makeRequest（$ requestArg = array（），$ eqLsRqst = array（），$ rqstPakg = array（））{
$this->beginTransaction();
parent::create($requestArg);
if(parent::count()){
$this->EqRqst_ID = parent::getLastInsertId();
$this->create($eqLsRqst);
if($this->count()){
foreach($rqstPakg as $pkg){
$this->_RequestPkg->create(array_merge(array('EqRqst_ID'=> $this->EqRqst_ID),$pkg));
if(!$this->_RequestPkg->count()){
$this->rollBack();
}
}
$this->commit();
}else{
echo 'Second Rollback';
$this->rollBack();
}
}else{
echo 'First Rollback';
$this->rollBack();
}
}
}
