我正在尝试使用$pull更新查询删除对文档的引用(为了删除所述文档)但是似乎没有发生任何事情.
我可以手动运行以下Mongo查询
db.collection.update({}, {
$pull: {
'field': {'$id': ObjectId("xxxxxxxx")}
}
}, false, true)
哪个工作正常.尝试在Doctrine的ODM中执行相同的操作既不会产生预期结果,也不会产生任何错误消息.这是我们到目前为止所拥有的
$id = new MongoId("xxxxxxxx");
$qb = $repo->createQueryBuilder();
$qb->update();
$qb->field('field')->pull(array('$id' => $id));
$qb->getQuery()->execute();
关于我做错了什么的暗示？
如果我这样做,print_r($pieces);我得到:

PHP致命错误:无法在第7行的/var/www/localhost/proba-function.php中重新声明proba()(之前在/var/www/localhost/proba-function.php:5中声明)

include …我有一个表单,在提交表单时输出以下http字符串:
Field109 = E01&Field112 = E05&Field209 =输入+在+信息+这里%21&Field110 = Field111 = Field113 = Field114 = Field115 = Field116 = Field117 = Field118 = Field119 = Field120 = CreatedBy =公共与dateCreated会= 2013年1月17日+ 08%3A43%3A45&ENTRYID = 14 IP = 98.246.50.81&HandshakeKey =
在我处理提交的PHP脚本中,我检查每个Field以查看它是否已设置.问题是,正如您在上面所看到的,如果表单中的字段在提交时为空,它仍然保留在HTTP字符串中,并isset()认为它已设置并进行处理我告诉它.
如何检查该字段是否真的为空？例如Field110,Field111应该为空,但我的PHP脚本认为它们已设置.
if (isset($_GET["Field110"])) {
array_push($apnsarray, "E02");
}
if (isset($_GET["Field111"])) {
array_push($apnsarray, "E03");
}
