我如何使用DashboardController和js从一个表到另一个表获取ID

Question

i've two tables;

exam_Marks table

{id, codeid, examMarks}

examCodes table

{id, codes, codeDesc}

am trying to fetch the id of codes from table examCodes and pass them to exam_marks table, however I can't earn this and i don't know where the problem is. can anyone please help or advice me to use another method

this is my app.js

$scope.examcodesList = function() {
    dataFactory.httpRequest(
        'dashboard/examcodeList',
        'POST',
        {},
        {"classes":$scope.form.codes}
    )
    .then(function(data) {
        $scope.subje = data.subje;
    });
}

and this is my DashboardController.php

public function examcodesList($classes = ""){
    $examcodesList = array();

    if(!Input::has('classes')){
        return $examcodesList;
    }
    $classes = Input::get('classes');

    if(is_array($classes)){
        return examcodes::whereIn('id',$classes)->get()->toArray();
    }else{
        return examcodes::where('id',$classes)->get()->toArray();
    }
}

Try with this. Not sure that's what you actually want.

if(is_array($classes)){
    return examcodes::join('exam_Marks', 'exam_Marks.codeid', '=', 'examCodes.id')
    ->whereIn('id',$classes)
    ->get()->toArray();
}else{
    return examcodes::join('exam_Marks', 'exam_Marks.codeid', '=', 'examCodes.id')
    ->where('id',$classes)
    ->get()->toArray();
}
