I am trying to migrate a PHP app from MySQL to SQLite, and some things that used to work, simply stopped working now. I am using PDO through a custom database wrapper class (the class is a singleton, seems logical to do it like that).
The problem: When trying to execute a query on a prepared statement, it throws a "fatal error: Call to a member function execute() on a non-object ...".
Relevant code (narrowed it down to this, after some hours of var_dumps and try-catch):
Connection string:
$this->connection = new PDO("sqlite:"._ROOT."/Storage/_sqlite/satori.sdb");
Obviously, the $connection variable here is a private variable from the class.
The error happens here (inside a function that is supposed to perform database insert):
try{
$statement = self::getInstance()->connection->prepare($sql);
}catch (PDOException $e){
print $e->getMessage;
}
try{
var_dump($statement);
$statement->execute($input);
}catch (Exception $e){
print $e->getMessage();
}
More accurately, it happens when I try to $statement->execute($input).
Any help appreciated. Thanks.
You are probably getting a mySQL error when the statement is being prepared, but you don't have PDO configured to throw an exception in case of an error.
<?php
$dbh = new PDO( /* your connection string */ );
$dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
// . . .
?>
