Question

i have below code in Laravel Model (class) to insert into database ,
but i get error: "
PDOException in ... SQLSTATE[42000] :syntax error ...
public function Add_new($Desc, $Cat_Name, $Loc_Name, $Loc_Des, $Comment, $Ven_Name)
{
$pdo = DB::connection()->getPdo();
$stmt = $pdo->prepare('
INSERT INTO itinv_category (name)
VALUES (:Cat_Name);
INSERT INTO itinv_location (name, Description)
VALUES (:Loc_Name,:Loc_Des);
INSERT INTO itinv_comment (text)
VALUES (:Comment);
INSERT INTO itinv_vendor (name)
VALUES (:Ven_Name);
SET #id1 = (SELECT MAX(id) FROM itinv_vendor);
SET #id2 = (SELECT MAX(id) FROM itinv_comment);
SET #id3 = (SELECT MAX(id) FROM itinv_location);
SET #id4 = (SELECT MAX(id) FROM itinv_category);
INSERT INTO itinv_inventory (category_id,location_id,vendor_id,comment_id,Description)
VALUES (#id4,#id3,#id1,#id2,:Desc);
');
$stmt->bindValue('Cat_Name', $Cat_Name);
$stmt->bindValue('Loc_Name', $Loc_Name);
$stmt->bindValue('Loc_Des', $Loc_Des);
$stmt->bindValue('Comment', $Comment);
$stmt->bindValue('Desc', $Desc);
$stmt->execute();
}
}

Answer 1

You are missing the Ven_Name:
$stmt->bindValue('Ven_Name', $Ven_Name);

Answer 2

i solved the problem , it was about ' pdo ' which can not operate multiple Mysql queries , we need to execute each query seperatley like below :
public function Add_new($Desc, $Cat_Name, $Loc_Name, $Loc_Des, $Comment, $Ven_Name)
{
// var_dump($Desc);
$stmt1 = ' INSERT INTO itinv_category (name)
VALUES (\'' . $Cat_Name . '\')';
$stmt2 = '
INSERT INTO itinv_location (name, Description)
VALUES (\'' . $Loc_Name . '\', \'' . $Loc_Des . '\')';
$stmt3 = 'INSERT INTO itinv_comment (text)
VALUES (\'' . $Comment . '\')';
$stmt4 = ' INSERT INTO itinv_vendor (name)
VALUES (\'' . $Ven_Name . '\')';
$stmt5 = 'SELECT MAX(id) AS id FROM itinv_vendor';
$stmt6 = 'SELECT MAX(id) AS id FROM itinv_comment';
$stmt7 = 'SELECT MAX(id) AS id FROM itinv_location';
$stmt8 = 'SELECT MAX(id) AS id FROM itinv_category';
$pdo = \DB::connection()->getPdo();
$stmt = $pdo->prepare($stmt1);
$stmt->execute();
$stmt = $pdo->prepare($stmt2);
$stmt->execute();
$stmt = $pdo->prepare($stmt3);
$stmt->execute();
$stmt = $pdo->prepare($stmt4);
$stmt->execute();
$stmt = $pdo->prepare($stmt5);
$stmt->setFetchMode(\PDO::FETCH_ASSOC);
$stmt->execute();
$arr = $stmt->fetchAll();
$Ven_ID = $arr['0']['id'];
$stmt = $pdo->prepare($stmt6);
$stmt->setFetchMode(\PDO::FETCH_ASSOC);
$stmt->execute();
$arr = $stmt->fetchAll();
$Comment_ID = $arr['0']['id'];
$stmt = $pdo->prepare($stmt7);
$stmt->setFetchMode(\PDO::FETCH_ASSOC);
$stmt->execute();
$arr = $stmt->fetchAll();
$Loc_ID = $arr['0']['id'];
$stmt = $pdo->prepare($stmt8);
$stmt->setFetchMode(\PDO::FETCH_ASSOC);
$stmt->execute();
$arr = $stmt->fetchAll();
$Cat_ID = $arr['0']['id'];
$stmt = $pdo->prepare('INSERT INTO itinv_inventory (category_id,location_id,vendor_id,comment_id,Description)
VALUES (:Cat_ID,:Loc_ID,:Ven_ID,:Comment_ID,:Desc)');
$stmt->bindValue('Cat_ID', $Cat_ID);
$stmt->bindValue('Loc_ID', $Loc_ID);
$stmt->bindValue('Comment_ID', $Comment_ID);
$stmt->bindValue('Ven_ID', $Ven_ID);
$stmt->bindValue('Desc', $Desc);
$stmt->execute();
}
}
