I want to run a PHP website on localhost. I set up the server and imported the database but getting the following error...I Downloaded the website from the client c_panel public HTML folder and exported the database. I have to do changes in front-end and I have no idea of PHP(I am a Node.js developer, so if you can reference it with that to help me.). I just want to start the website locally, so that I can do the front-end changes. I'm getting the following error in my app/Models.php

Update this line of code
public static function redirect($endpoint){

}
Or, you can create an instance of this class.
$response = new Response();
Then call this method.
$response->redirect('404');

I'm passing an array of values through a bind_param function, the way I do this is like this:
<?php
class Query{
private $_mysqli;
/*
* #param object $mysqli
*/
public function __construct($mysqli)
{
$this->_mysqli = $mysqli;
}
/*
* #param string query
* #param string $types
* #param array $values
*/
public function read($query = "", $type = "", $params = array())
{
$query = ($query === "") ? die("Read error: Query") : $query;
$type = ($type === "") ? die("Read error: Type") : array($type);
$params = (count($params) == 0) ? die("Read error: Params") : $params;
$values = array();
foreach($params as $key => $value) {
$values[$key] = &$params[$key];
}
if ($stmt = $this->_mysqli->prepare($query))
{
call_user_func_array(array($stmt, "bind_param"), array_merge($type, $values));
$stmt->execute();
$fields = array();
for($i=0; $i<count($params); $i++){
$fields[$i] = $params[$i];
}
call_user_func_array(array($stmt, "bind_result"), $fields);
$array = array();
while($data = $stmt->fetch())
{
$array[] = $data;
}
return $array;
}
}
}
This is the way I use my function
<?php
//$mysqli is the mysqli connection
$query = new Query($mysqli);
$query_str = "SELECT * FROM users WHERE voornaam = ? AND achternaam = ?";
$types = "ss";
$params = array("Firstname", "Lastname");
var_dump($query->read($query_str, $types, $params));
?>
The part where I get stucked is:
<?php
$fields = array();
for($i=0; $i<count($params); $i++){
$fields[$i] = $params[$i];
}
call_user_func_array(array($stmt, "bind_result"), $fields);
$array = array();
while($data = $stmt->fetch())
{
$array[] = $data;
}
?>
Im not sure where it goes wrong, I have a feeling at the while loop.
hope you guys can help me making this function working :)
you are binding results , so you don't need to assign your fetched data to new variable,
mysqli_stmt::bind_result -- mysqli_stmt_bind_result — Binds variables
to a prepared statement for result storage
while you are using call_user_func_array , and according to this comment, your loop :
while($data = $stmt->fetch())
{
$array[] = $data;
}
may be as follows:
while($stmt->fetch())
{
// params which you had bind it into bindParams
$array[] = $params;
}

<?php $this->mysqldb->insert($table, $data); ?>
<?php }?>
Problem is in this line
$mysqldb = new MysqlDB();
The constructor requries arguments which are not passed. You need to pass $host, $username, $password, $db to constructor.
Your code acutally makes no sense. You could use $DB instead of creating new object. You also use $this->mysqldb in no object context. There are plenty of errors in your code.
To fix:
Remove this line $mysqldb = new MysqlDB();
Change <?php $this->mysqldb->insert($table, $data); ?> to $DB->insert($table, $data);
Script should +- look like:
<?php
ob_start();
session_start();
require_once("phpinclude/include/membersite_config.php");
require_once("phpinclude/include/MySqlDB.php");
$DB = new MysqlDB('172.90.13.97','king','mi*****hhh','kxxxx_database');

I was looking this database approach and it seems very practical and useful. I'm beginner at oop and still learning. The requestQuote would look something like this:
How do I bindParam in query like this?
requestQuote = DB::getInstance()->query(""); (form DB.class)
This is code I have right now:
$request = "";
if ($_POST) {
$request = $_POST["request"];
} else if (isset($_GET["request"])) {
$request = $_GET["request"];
}
$requestQuote="%" . $request . "%";
$sql = $conn -> prepare("SELECT * FROM users WHERE concat(name, ' ',lastname, ' ', user_id) LIKE :request limit " . (($page * 50)-50) . ",50");
$sql->bindParam(":request", $requestQuote);
$sql -> execute();
$results = $sql -> fetchAll(PDO::FETCH_OBJ);
When I put it like this, then pagination works. But I need search form... and that won't work...
$sql= DB::getInstance()->query(
"SELECT * FROM users
WHERE (category='admin')
LIMIT " . (($page* 5)-5) . ",5");
#Paul was close but you got one more issue:
Check this part of the class:
$x = 1;
if(count($params)) {
foreach($params as $param) {
$this->_query->bindValue($x, $param);
$x++;
}
}
It is not binding with named place holder, you need to change the code:
$limit = ($page * 50)-50;
$params = array('%lolcats%', $limit);
$query =
"SELECT * FROM users
WHERE concat(name, ' ',lastname, ' ', user_id)
LIKE ?
LIMIT ?,50";
$results = DB::getInstance()->query($query, $params);
or change the class code to bind by placeholder, something along the following lines:
#$params = array(':request' =>'%lolcats%', ':limit'=>$limit);
if(count($params)) {
foreach($params as $key=>$value) {
$this->_query->bindValue($key, $value);
}
}
Looking at this class, the second argument of query function is an optional array of parameters so use this to pass the parameters for your request:
$params = array(':request' => 'lolcats');
$limit = $page - 1 * 50;
$query = sprintf(
"SELECT * FROM users
WHERE concat(name, ' ',lastname, ' ', user_id)
LIKE :request
LIMIT %d,50",
$limt
);
$results = DB::getInstance()->query($query, $params);
I have a HTML form which has more than 25 entries.
I know how to insert normal form data into MySQL database using PHP PDO. But I just want to know if there is any alternative way in which I can store the form entries to an array and insert the data into database using the array.
Because writing an insert statement for more than 25 columns is cumbersome.
You could always use a PDO wrapper class, I use the class below to handle most of my PDO queries:
class DB {
protected
// Return from mysql statement
$data = array(),
// Used for checking whether something was added to the JSON object and remove it if the table column doens't exist
$table_cols = array(),
// Storing the table name we are working with
$table = '';
protected static
// PDO connection to the DB
$_conn = null,
// The DB credentials retrieved from the ini file
$_credentials = array ();
private
$_id = -1,
$_keys = array(),
$_values = array(),
$_last_insert_id = -1,
$_results = array();
//
// PUBLIC FUNCTIONS
//
public function __construct () {
if (self::$_conn === null) {
self::setCredentials();
try {
self::$_conn = new \PDO("mysql:host=" . self::$_credentials['host'] . ";dbname=" . self::$_credentials['dbname'] , self::$_credentials['username'], self::$_credentials['password']);
} catch (\PDOException $e) {
DebugLog::instance('DB')->error($e, 'db_connection');
}
}
}
public function insert ($data) {
$data = $this->checkCols($data);
// Allows us to quickly clone data by removing the id and inserting as a new record
if (isset($data['id'])) {
unset($data['id']);
}
$this->data = $data;
$this->setDataBinding();
$sql = "INSERT INTO `" . self::$_credentials['dbname'] . "`.`{$this->table}` (`" . implode('`, `', $this->_keys) . "`) VALUES (:" . implode(', :', $this->_keys) . ");";
return $this->prepareAndExecute($sql);
}
public function update ($data) {
$data = $this->checkCols($data);
if (!isset($data['id'])) {
// Houston we have a problem, there needs to be an id to update a record
DebugLog::instance('DB')->error("No ID set for Update: " . implode(', ', array_keys($data)), 'db_id_' . $this->table);
} else {
// We need to unset the id because it shouldn't be in the data binding
// But we still hold onto it for the where clause
$id = $data['id'];
unset($data['id']);
$this->data = $data;
$this->setDataBinding();
$sql = "UPDATE `" . self::$_credentials['dbname'] . "`.`{$this->table}` SET ";
$query_string = "";
foreach ($this->_keys as $i => $key) {
$query_string .= "`{$key}` = :{$key}, ";
}
$query_string = trim($query_string);
if (substr($query_string, -1) === ',') {
$query_string = substr($query_string, 0, -1);
}
$sql .= $query_string . " WHERE `id` = '{$id}'";
return $this->prepareAndExecute($sql);
}
return false;
}
public function remove ($id) {
$this->rawQuery("DELETE FROM `{$this->table}` WHERE `id` = '{$id}';");
}
public function rawQuery ($sql) {
try {
$pdo = self::$_conn->query($sql);
$pdo->setFetchMode(\PDO::FETCH_ASSOC);
} catch (\PDOException $e) {
DebugLog::instance('DB')->error($e, 'db_query_' . $this->table);
return array();
}
return $pdo->fetchAll();
}
//

} catch (\PDOException $e) {
DebugLog::instance('DB')->error($e, 'db_' . $this->table);

private function checkCols ($array) {

if (!in_array($col, $this->table_cols)) {

}

return $array;
}
private static function setCredentials () {
// I actually use a config file here, instead of hard coding

$this->table = '';
self::$_conn = null;
$this->_keys = array();
$this->_values = array();

$this->_results = array();
}
}
Then for each table, create a class that extends the class above. For example, lets say we have a users table:
class UsersTable extends DB {
public function __construct () {
// Parent constructor creates the DB connection
parent::__construct();
// Now let's set the desired table based on this class
$this->table = "users";
// Set the table columns, for mysql column validation
$this->table_cols = $this->initColumns();
}
}
Usage is than as simple as:
$table = new UsersTable();
$table->insert($record);
As long as your array has the 25 values in the same order as the table you can use unnamed parameters and lazy binding See PDO info
$sql ="INSERT INTO table_name VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,)";
$stmt = $dbh->prepare($sql);
$stmt->execute($array);
I have a very simple select query using pdo but it is not working.
The generic sql query is
$sql = "select * from table where type != 'address' and type != 'multipleimage'";
Now in pdo I have
$fieldtype = array('address','multipleimage');
$query = $this->db->prepare("SELECT * from table where
(type not in $type) and (userid !=:userid) ");
$query->execute(array(':userid' => 2, $fieldtype ));
Now getting notice + warning
Notice is ' Array to string conversion....'
Warning is 'Warning: PDOStatement::execute(): SQLSTATE[42000]: Syntax error or access violation.....'
Why don't you use NOT IN clause like:
$sql = "select * from table where type not in ('address','multipleimage')";
Something like this, you may have to do some minor changes
<?php
$fieldtype = array('address','multipleimage');
$inQuery = implode(',', array_fill(0, count($fieldtype), '?'));
$db = new PDO(...);
$stmt = $db->prepare(
'select * from table where type not in(' . $inQuery . ')'
);
// bindvalue is 1-indexed, so $k+1
foreach ($ids as $k => $id)
$stmt->bindValue(($k+1), $fieldtype);
$stmt->execute();
?>
I have created my own ORM like class called DBConnection.php. It does all CRUD functionalities for any table in the specified database. It uses PDO as well. Feel free to play with it, customize and use in your code if you would like to....
