how to insert multiple row data based on checkbox selection in Laravel - mysql

Question

I'm stuck with multiple row insertion in laravel. I keep on getting an error which says:
Trying to access array offset on value of type null.
blade.php file:
<tbody>
#forelse($GIV as $GIV)
<tr>
<td> <input type="checkbox" name="status[{{$GIV->id}}]" id="status" value="Issued" ></td>
<td> <input type="text" class="form-control" id="id" name="item_id[{{$GIV->id}}]" hidden="" value="{{$GIV->id}}">{{$GIV->id}}</td>
<td> <input type="text" class="form-control" id="pr_no" name="pr_no[{{$GIV->id}}]" hidden="" value="{{$GIV->pr_no}}">{{$GIV->pr_no}}</td>
<td> <input type="text" class="form-control" id="dep_name" name="dep_name[{{$GIV->id}}]" hidden="" value="{{$GIV->dep_name}}">{{$GIV->dep_name}}</td>
<td> <input type="hidden" class="form-control" id="item_name" name="item_name[{{$GIV->id}}]" value="{{$GIV->item_name}}">{{$GIV->item_name}}</td>
<td> <input type="text" class="form-control" id="description" name="description[{{$GIV->id}}]" hidden="" value="{{$GIV->description}}" >{{$GIV->description}}</td>
<td> <input type="number" class="form-control" id="item_qty" name="item_qty[{{$GIV->id}}]" hidden="" value="{{$GIV->item_qty}}">{{$GIV->item_qty}}</td>
<td> <input type="text" class="form-control" id="unit_measure" name="unit_measure[{{$GIV->id}}]" hidden="" value="{{$GIV->unit_measure}}">{{$GIV->unit_measure}}</td>
<td> <input type="number" class="form-control" id="authorized_qty" name="authorized_qty[{{$GIV->id}}]" hidden="" value="{{$GIV->authorized_qty}}">{{$GIV->authorized_qty}}</td>
</tr>
#empty
<tr><td colspan="16"><center>No Data Found</center</td></tr>
#endforelse
</tbody>
Controller file:
public function addDataGIV(Request $request)
{
$data =request()->all;
foreach(request()->status as $status) {
DB::table('g_i_v_s')->insert(
[
'item_id' =>$data['item_id'][$status],
'item_name' =>$data['item_name'][$status],
'description' =>$data['description'][$status],
'item_qty' =>$data['item_qty'][$status],
'unit_measure' =>$data['unit_measure'][$status],
'authorized_qty'=>$data['authorized_qty'][$status],
'dep_name' =>$data['dep_name'][$status],
'pr_no' =>$data['pr_no'][$status],
]
);
}
}
When a user selects the checkbox and clicks the submit button, I want only the selected checkbox row including the checkbox value to be stored into the database, without any errors.

You're actually quite close, but you're accessing your Array indices wrong; $status, if defined properly, would be Issued, which is not what you want. Also, request()->all is null, but request()->all() (with the ()) would be an Array of your form input; hence the error when trying to use $data[...][...]; later.
This code should work (Note: you don't need $data at all here):
foreach(request()->input('status', []) as $index => $status) {
DB::table('g_i_v_s')->insert([
'item_id' => request()->input("item_id.{$index}"),
'item_name' => request()->input("item_name.{$index}"),
'description' => request()->input("description.{$index}"),
'item_qty' => request()->input("item_qty.{$index}"),
'unit_measure' => request()->input("unit_measure.{$index}"),
'authorized_qty' => request()->input("authorized_qty.{$index}"),
'dep_name' => request()->input("dep_name.{$index}"),
'pr_no' => request()->input("pr_no.{$index}"),
]);
}
Alternative syntax would be request->input('item_id')[$index], like:
foreach(request()->input('status', []) as $index => $status) {
DB::table('g_i_v_s')->insert([
'item_id' => request()->input('item_id')[$index],
'item_name' => request()->input('item_name')[$index],
'description' => request()->input('description')[$index],
'item_qty' => request()->input('item_qty')[$index],
'unit_measure' => request()->input('unit_measure')[$index],
'authorized_qty' => request()->input('authorized_qty')[$index],
'dep_name' => request()->input('dep_name')[$index],
'pr_no' => request()->input('pr_no')[$index],
]);
}
Basically, when looping over request()->input('status', []), you have access to $index, and $status (which is not referenced, but that's ok). $index will be equivalent to whatever $giv->id is on the front-end, and each field exists as an Array Index with that value, so looping and referencing is super easy.
