我TblStudent在 mongodb 中有一个集合

       {
      "_id": ObjectId("5baa85041d7859f40d000029"),
       "Name": "John Doe",
       "RollNo": 12,
       "Class": "Ist"
        ....
       }

我还有一个TblRoute像

   {
   "_id": ObjectId("5baa818d1d78594010000029"),
   "Name": "New york City",
   "StopDetails": [
   {
    "StopId": "abc777",
    "Name": "Block no 3"
   },
   {
   "StopId": "abc888",
   "Name": "Block no 4"
   }
 ],
"NumberOfSeats": "10",
"StudentDetails": [
 {
   "StudentId": ObjectId("5baa85041d7859f40d000029"),
   "VehicleId": "7756"
  },
  {
   "StudentId": ObjectId("5baa85f61d7859401000002a"),
   "VehicleId": "7676"
 }
 ]
}

我正在使用 mongodb 3.6 平台。我正在使用以下代码行

       $query = ['_id' => new MongoDB\BSON\ObjectID($this->id)];
    $cursor = $this->db->TblRoute->aggregate([
    ['$match' => $query], …

我动态生成了html

<div id="dynamic-contact-details" class="col-sm-7">
    <div id="count0" class="space">
        <div class="col-sm-3">
            <select id="contact-type0" class="form-control"><option value="">Select</option><option value="Phone">Phone</option><option value="Whatapp">Whatapp</option><option value="Facebook">Facebook</option><option value="Web">Web</option><option value="Fax">Fax</option></select><small id="contact-type0" class="text-danger hide">Contact Type is Required</small>
        </div>
        <div class="col-sm-8">
            <input type="text" name="contact-type-value0" id="contact-type-value0" class="form-control"><small id="contact-type-value0" class="text-danger hide">Contact Type Value is Required</small>
        </div>
        <button value="count0" class="remove_field btn btn-white"><i class="fa fa-trash"></i></button></div>
    <div id="count2" class="space">
        <div class="col-sm-3">
            <select id="contact-type2" class="form-control"><option value="">Select</option><option value="Phone">Phone</option><option value="Whatapp">Whatapp</option><option value="Facebook">Facebook</option><option value="Web">Web</option><option value="Fax">Fax</option></select><small id="contact-type2" class="text-danger hide">Contact Type is Required</small>
        </div>
        <div class="col-sm-8">
            <input type="text" name="contact-type-value2" id="contact-type-value2" class="form-control"><small id="contact-type-value2" class="text-danger hide">Contact Type Value …

我写了下面的代码行来获取查找中的一些特定字段，例如

       $pipeline = array(
            array(
                '$match' => $query
            ),
            array(
                '$lookup' => array(
                    'from' => 'studentTbl',
                    'localField' => '_id',
                    'foreignField' => 'activity_details.activityId',
                     'pipeline' => [
                        ['$project' => [ '_id' =>  1.0, 'activity_details' => 1.0] ],
                     ],   
                    'as' => 'studentsOfActivities'
                )
            ),
           ....
           ....
        );

     return $this->db->activitiesTbl->aggregate($pipeline)->toArray();

基本上 studentTbl 有许多字段和嵌入的文档。在上面的代码中，我首先使用外部和本地字段通过查找获取，然后确定哪些字段应该投影到管道内。

上面的代码不起作用...请帮忙！！！

我在我的 php 应用程序“ https://respect-validation.readthedocs.io/en/1.1/rules/Each/ ”中使用来自此来源的尊重内置验证。我通过 ajax 调用将数据传递给 php 应用程序代码，例如

print_r($itemsArray);

Array
(
  [0] => Array
    (
        [itemName] => apple
    )

 [1] => Array
    (
        [itemName] => banana
    )

 [2] => Array
    (
        [itemName] => cherry
    )
)

我已将验证应用于 php 代码端的以下字段。

   $fullName = $_REQUEST['fullName'];
   $email = $_REQUEST['email'];
   $phoneNumber = $_REQUEST['phoneNumber'];
   $age = $_REQUEST['age'];
   $itemsArray = $_REQUEST['itemsArray'];

   try 
   {
      v::key('fullName', v::notEmpty()->setTemplate("Full Name: Required field"))
       ->key('fullName', v::alpha()->setTemplate("Full Name: Alphabets only"))
       ....
       ....
       ->key('itemsArray', v::arrayVal()->each(v::alpha())->setTemplate("Item must contain Alphabets"))

         ->assert(['fullName' => $fullName, 'email' => $email, …
