How to write a condition based query? - laravel

Question

I have a query to run based on the user type selected. I have around 9 users. Based on 9 users, only first line will be different remaining conditions are going to be same.
Below is the code I am writing. I dont want to repeat the same line again for 9 users.
How can I this query without repeating the condition?
if($user_id == 1) {
$slmids = Production::groupBy('gid', 'rid', 'aid', 'sid')
//same
->where("yrsno", $currentYear)
->orderBy("order")
->orderBy("rid")
->orderBy("aid")
->get(['gid', 'rid', 'aid', 'sid'])
->toArray();
}
else if($user_id == 2) {
$slmids = Production::where('gid', $user['sgrp'])
//same
->where("yrsno", $currentYear)
->orderBy("order")
->orderBy("rid")
->orderBy("aid")
->get(['gid', 'rid', 'aid', 'sid'])
->toArray();
}
else if($user_id == 3){
.....
}

Answer 1

$production = Production::where("yrsno", $currentYear)
->orderBy("order")
->orderBy("rid")
->orderBy("aid")
->get(['gid', 'rid', 'aid', 'sid']);
if ($user_id == 1) {
$production = $production->groupBy('gid', 'rid', 'aid', 'sid');
} else if($user_id == 2) {
$production = $production->where('gid', $user['sgrp']);
} else if($user_id == 3) {
....
}
$result = $production->toArray();
You can try like this way.

Answer 2

$slmids = Production::where("yrsno", $currentYear);
if ($user_id == 1)
$slmids = $slimds->groupBy('gid', 'rid', 'aid', 'sid');
elseif ($user_id == 2)
$slmids = $slmids->where('gid', $user['sgrp']);
...
// you can use switch-case if you want
$slmids = $slmids->orderBy('order')
->orderBy('rid')
->orderBy('aid')
->get(['gid', 'rid', 'aid', 'sid'])
->toArray();
I believe groupBy must be placed first before orderBy

Answer 3

Use When to make easy Try following code:
$production = Production::where("yrsno", $currentYear)
->orderBy("order")
->orderBy("rid")
->orderBy("aid")
->query();
$production->when($user_id == 1, function ($query) {
$query->groupBy('gid', 'rid', 'aid', 'sid');
});
$production->when($user_id == 2, function ($query) use ($user) {
$query->where('gid', $user['sgrp']);
});
$results = $production->get()->toArray();
