How to insert multiple rows into a table at one time? - php

Question

I need to send e.g. 5 records in one query into the one table (id_book - is every time different), so I need to by one click on button, create e.g. 10 records. This code shows this Error message:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'id_book.0' in 'where clause' (SQL: select count() as aggregate from connect_user_books where id_book.0 = 6* (MY TEXT: 6 IS ID OF MY LIST INTO WHICH I NEED TO ADD THEASE RECORDS))
My controller:
public function create()
{
$books = Book::all();
return view('connectUserBook.create', compact('books'));
}
public function store(Request $request)
{
$this->validate($request, [
'id_user_select' => 'required',
'id_book' => 'required|array',
'id_book.*' => 'exists:connect_user_books',
]);
$userId = $request->input('id_user_select');
// Vytvoření
foreach ($request->input('id_book') as $book) {
$connect = new ConnectUserBook;
$connect->id_user_select = $userId;
$connect->id_book = $book;
$connect->save();
}
return redirect('/dashboard')->with('success', 'Výběr editován!');
}
My HTML markup:
{{ Form::open(['action' => 'ConnectUserBookController#store', 'method' => 'POST']) }}
<div>
<label class="form-label">Vybraný výběr *</label>
<div>
<select name="id_user_select" class="form-control">
<?php
$select_id = $_GET["id"];
$select_id;
$res = mysqli_query($link, "select * from selected_books Where id = $select_id");
while($row = mysqli_fetch_array($res))
{
?>
<option value="<?php echo $row["id"]; ?>"> <?php echo $row["title"]; ?></option>
<?php
}
?>
</select>
</div>
</div>
<br>
#for ($i = 0; $i < 11; $i++)
<div>
<label class="form-label">Book {{ $i }} *</label>
<div>
<select name="id_book[]" class="form-control">
#foreach ($books as $book)
<option value="{{ $book->id_book }}">{{ $book->nazev }} - {{ $book->pocet_stranek }} stran</option>
#endforeach
</select>
</div>
</div>
#endfor
{{Form::submit('Submit', ['class' => 'btn btn-primary'])}}
{{ Form::close() }}

Answer 1

Make an array and use the insert method with eloquent.
$data = array()
foreach ($request->input('id_book') as $book) {
$data[] = array('id_user_select'=>$userId,'id_book'=>$book);
}
ConnectUserBook::insert($data);
as per your error your need to specify with the column. add a column to compare with which column exists?
'id_book.*' => 'exists:connect_user_books,column_name',
Note :- It doesn't insert the timestamps.
