PHP Mongo aggregate match regex - php

Question

Performing a query that simulates a 'like/mysql' searching for teams on the name of the team
Team document structure
{
"_id": 9,
"name": "azerty",
"tag": "dsfds",
"desc": "ggdfgsdfgdfgdf",
"captain": 8,
"coach": 8,
"members": [{
"date_joined": "2016-03-31 15:22:09",
"user_id": 8
}, {
"date_joined": "2016-03-31 19:22:35",
"user_id": 9
}],
"current_invites": [{
"invite_id": 21,
"username": "Nikki",
"user_id": "9",
"status": 1,
"date_invited": "2016-03-31 18:32:40"
}, {
"invite_id": 22,
"username": "Nikki",
"user_id": "9",
"status": 2,
"date_invited": "2016-03-31 18:33:16"
}]
}
PHP Code =
$q = '/.*'.$q.'*./';
$result = $this->coll->aggregate(
array('$match' => array('name' => $q)),
array('$project' => array('name' => 1,'members' => array('$size' => '$members'))));
Feels like I'm going mad not knowing how to fix this.
Have used regex before after migrating to mongo but not with the combination of agg-match.

Answer 1

in my case i am finding the aggregated result in which you can not set the where clause so use the aggregated functions like $sort $unwind $orderby and so on i am using the all of the above mention and have the problem with the like stuff to match the string like %str% here my code in which i implement the like using $match with MongoRegex
public function getRecords($table,$where = array(),$like_key = false,$like_value = false,$offset = 1,$limit = 10,$order_column = false,$order_type = false, $isAggregate=false,$pipeline=array()){
$temp = $this->getMongoDb()->where($where);
if($like_key && $like_value){
$temp = $temp->like($like_key,$like_value);
// this like filter is for aggregated result work both on normal get record or by aggregated result
$pipeline[]=array(
'$match' => array( $like_key => new MongoRegex( "/$like_value/i" ) )
);
}
if($order_column && $order_type){
$order_by = array();
$order_by[$order_column] = $order_type;
$temp = $temp->order_by($order_by);
$pipeline[]=array(
'$sort'=>array($order_column => ($order_type =="desc")? -1 : 1)
);
}
I got the solution when I read the following aggregation framework go the aggregation framework
I hope you will get your solution to resolve your issue.
