基于Doctrine文档$qb->getQuery()->execute();将返回一个游标给你迭代结果，但$qb->find($criteria);返回实际找到的文档。
我正在使用symfony2 MongoDBbundle，我希望避免迭代Repository类中的结果集。
// Returns Product Document
$entity = $this->get('doctrine_mongodb')
->getRepository("MyBundle:Product")
->findOneBy(array('title' => 'somthing'));
// Returns Cursor
$entity = $this->get('doctrine_mongodb')
->getRepository("MyBundle:Product")
->customFunctionWithcreateQueryBuilder(array('title' => 'somthing'));
如何让cutomFunctionWithcreateQueryBuilder()返回与findOneBy相同的类/结果？
另外如何使execute()返回所有嵌入文档？
修改
cutomFunctionWithcreateQueryBuilder的内容：
class ProductRepository extends DocumentRepository {
public function customFunctionWithcreateQueryBuilder($param, $hydrate = true) {
$query = $this->createQueryBuilder()
->select()
->hydrate($hydrate);
if (isset($param['unique_id'])) {
$query->field('id')->equals($param['unique_id']);
}
return $query->getQuery()->execute();
}
}

如果您只想要一个结果并将eagerCursor设置为true，则可以使用<meta charset="utf-8" />
<?php
include 'config.php';
mysqli_set_charset($db, 'utf8');
$id = $_COOKIE["id"];
if (isset($_POST["action"])){
$newname = substr(md5(rand() * time()), 5,10);
$folder = "image/";
$folder2 = "image/thumb/";
$filetmp = $_FILES["filep"]["tmp_name"];
$filename = $_FILES["filep"]["name"];
$filetype = $_FILES["filep"]["type"];
$filesize = $_FILES["filep"]["size"];
$fileinfo = getimagesize($_FILES["filep"]["tmp_name"]);
$filewidth = $fileinfo[0];
$fileheight = $fileinfo[1];
$filepath = "$folder".$newname.$filename;
$filepath_thumb = "$folder".$filename;
if($filetmp == ""){
echo "Upload image";
}
else {
if($filesize > 2097152){
echo "Less then 2 mb";
}
else{
if($filetype != "image/jpeg" && $filetype != "image/png"
&& $filetype != "image/gif" && $filetype != "image/jpg"){
echo ".jpeg, .jpg, .gif, .png";
}
else{
move_uploaded_file($filetmp,$filepath);
if($filetype == "image/jpeg"){
$imagecreate = "imagecreatefromjpeg";
$imageformat = "imagejpeg";
}
if($filetype == "image/png"){
$imagecreate = "imagecreatefrompng";
$imageformat = "imagepng";
}
if($filetype == "image/gif"){
$imagecreate= "imagecreatefromgif";
$imageformat = "imagegif";
}
if($filetype == "image/jpg"){
$imagecreate= "imagecreatefromjpg";
$imageformat = "imagejpg";
}
$new_width = "200";
$new_height = "150";
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = $imagecreate($filepath); //photo folder
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $filewidth, $fileheight);
$imageformat($image_p, $filepath_thumb);//thumb folder
$res = mysqli_query($db, "UPDATE Imager SET Cover='".$newname.$filename."' WHERE IDImg ='$id'");
if($res) {
echo "Good.";
}
else {
echo "Not Good.";
}
}
}
}
}
header( "Refresh:2; url=img.php", true, 303);
?>
一次获取所有数据。例如：
getSingleResult()
