It should be $instID = $request->institution;
Thanks for all your helps..
UPDATE
I trying to insert to CRConfigDetail Model / table, but first I need to get my CRConfigID from CRConfig Model / Table with specific rules. So I can get the CRConfigID and put it to CRConfigDetail column.
But every time I trying to retrieve, it always give empty data even I already have data at my database. In other Controller I can retrieve data with similar rules.
Am I do something wrong with logic? Because I don't see any errors.
Here is my HTML / form:
<form action="doInsertSCC" method="POST" enctype="multipart/form-data" id="scheduleDetailForm">
{{csrf_field()}}
<div class="form-group">
<label for="institution">Institution</label>
<select name="institution" class="form-control" id="institution">
</select>
</div>
<div class="form-group">
<label for="acadCareer">Academic Career</label>
<select name="acadCareer" class="form-control" id="acadCareer">
</select>
</div>
<div class="form-group">
<label for="period">Period</label>
<select name="period" class="form-control" id="period">
</select>
</div>
<div class="form-group">
<label for="department">Department</label>
<select name="department" class="form-control" id="department">
</select>
</div>
<div class="form-group">
<label for="fos">Field of Study</label>
<select name="fos" class="form-control" id="fos">
</select>
</div>
<div class="form-group">
<label for="scc">Lecturer's ID - Name</label>
<select name="scc" class="form-control" id="scc">
</select>
</div>
<button type="submit" class="btn btn-default">Assign SCC</button>
<div id="search" class="btn btn-default">Search</div>
</form>
Here is my Route to access my Controller
Route::post('/doInsertSCC', "ScheduleController#insertSCC");
And here is my ScheduleController
public function insertSCC(Request $request){
$this->validate($request, [
'scc' => 'required'
]);
$instID = $request->insititution;
$acadID = $request->acadCareer;
$termID = $request->period;
$depID = $request->department;
$rule = ['institutionID' => $instID, 'acadCareerID' => $acadID, 'termID' => $termID, 'departmentID' => $depID];
$crConfig = CRConfig::where($rule)->first();
if( !empty($crConfig) ){
foreach ($crConfig as $cr) {
$crConfigID = $cr->CRConfigID;
}
$schedule = new CRConfigDetail;
$schedule->status = 'Pending';
$schedule->numRevision = 0;
$schedule->FOSID = $request->fos;
$schedule->SCC = $request->scc;
$schedule->CRConfigID = $crConfigID;
$schedule->save();
return redirect("AssignSCC")->with('status', 'Add SCC success!');
}else{
return redirect("AssignSCC")->with('status', 'Add schedule first!');
}
}
I already check my rules data are match with my CRConfig table's data (using console.log()
Everytime I submit this form, I will do the "else" and redirect with "Add schedule first!" message.

Answer 1

Actually, it does accept an array, but the array should be formatted as such..
$rule = [
['institutionID', '=', $instID],
['acadCareerID', '=', $acadID],
['termID', '=', $termID],
['departmentID', '=', $depID]
];

Answer 2

use the below one
$crConfig = CRConfig::where('institutionID' , $instID)
->where('acadCareerID' , $acadID)
->where('termID', $termID)
->where('departmentID', $depID)
->first();
instead of
$rule = ['institutionID' => $instID, 'acadCareerID' => $acadID, 'termID' => $termID, 'departmentID' => $depID];
$crConfig = CRConfig::where($rule)->first();
You can check the query built at the backend by getting the query log, for this you have to enable the query log before the query gets built and get the query log after the query gets built both query log methods belongs to DB facade
\DB::enableQueryLog();
\DB::getQueryLog();
