PDO not inserting - error code 00000 - php

Question

I have an issue with my INSERT query, $pdo->execute return false, with error code 00000
Query
string 'INSERT INTO module_test (img_name, description, priority) VALUES(:img_name, :description, :priority)' (length=100)
errorInfo() return:
array (size=3)
0 => string '00000' (length=5)
1 => null
2 => null
Code:
private function Init($query, $parameters = "")
{
# Connect to database
if (!$this->bConnected) {
$this->Connect();
}
try {
# Prepare query
$this->sQuery = $this->pdo->prepare($query);
# Add parameters to the parameter array
$this->bindMore($parameters);
# Bind parameters
if (!empty($this->parameters)) {
foreach ($this->parameters as $param => $value) {
$type = PDO::PARAM_STR;
switch ($value[1]) {
case is_int($value[1]):
$type = PDO::PARAM_INT;
break;
case is_bool($value[1]):
$type = PDO::PARAM_BOOL;
break;
case is_null($value[1]):
$type = PDO::PARAM_NULL;
break;
}
// Add type when binding the values to the column
$this->sQuery->bindValue($value[0], $value[1], $type);
}
}
# Execute SQL
var_dump($query);
var_dump($this->sQuery->execute());
var_dump($this->sQuery->errorInfo());
}
catch (PDOException $e) {
# Write into log and display Exception
echo $this->ExceptionLog($e->getMessage(), $query);
die();
}
# Reset the parameters
$this->parameters = array();
}
public function query($query, $params = null, $fetchmode = PDO::FETCH_ASSOC)
{
$query = trim(str_replace("\r", " ", $query));
$this->Init($query, $params);
$rawStatement = explode(" ", preg_replace("/\s+|\t+|\n+/", " ", $query));
# Which SQL statement is used
$statement = strtolower($rawStatement[0]);
if ($statement === 'select' || $statement === 'show') {
return $this->sQuery->fetchAll($fetchmode);
} elseif ($statement === 'insert' || $statement === 'update' || $statement === 'delete') {
return $this->sQuery->rowCount();
} else {
return NULL;
}
}
public function insert($table, $keyValue)
{
$fieldString = '';
$valueString = '';
$i = 1;
foreach ($keyValue as $key => $currKeyValue)
{
$fieldString .= $key;
$valueString .= ':'.$key;
if($i != count($keyValue))
{
$fieldString .= ', ';
$valueString .= ', ';
}
$i++;
}
$query = 'INSERT INTO '.$table.' ('.$fieldString.') VALUES('.$valueString.')';
$this->query($query, $keyValue);
}
Parameters array
F:\Dev\wamp\wamp64\www\include\class\Database.class.php:216:
array (size=3)
'img_name' => string 'ttt1' (length=4)
'description' => string 'ttt1' (length=4)
'priority' => int 0
I already try this query in phpmyadmin and everything worked well.
If someone know how to solve this?
thanks
PS: sorry for my bad english

PDO is reported not to fill the errorInfo property in certain circumstances.
Instead, you have to make it throw an exception, which is the most reliable way to get the error message. To do so, in your constructor, add this line
$this->pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
Also note that your class is a genuine example of all the mistakes one could make writing a PDO wrapper. I compiled the most popular mistakes in an article, Your first database wrapper's childhood diseases and your class contains every single one of them.
