I have received the following error:"Fatal error: Call to a member function session_type() on a non-object".
Supposedly I'm not creating an object in the variable "$tabsessiontype2". I don't see the reason why the object isn't created. Thanks for you help.
Here is my TeacherController.php
if(isset($_POST['search']) && $_POST['sessiontype_name']){
$tabsessiontype2=Db::getInstance()->select_session_type2($_POST['sessiontype_name']);
if($tabsessiontype2->session_type()=='X'){
$view='teacher.php';
}
elseif($tabsessiontype2->session_type()=='XO'){
$view='teacherxo.php';
}
elseif($tabsessiontype2->session_type()=='note'){
$view='teachernote.php';
}
}
This is the function I call:
public function select_session_type2($name_session_type) {
$query = "SELECT * FROM session_types WHERE session_types.name_session_type='$name_session_type'";
$result = $this->_db->query($query);
$tableau = array();
if ($result->rowcount()!=0) {
while ($row = $result->fetch()) {
$tableau[] = new Sessiontype($row->code_session_type,$row->name_session_type,$row->quarter_session_type,$row->code_lesson,$row->session_type);
}
}
return $tableau;
}
Here is the SessionType class:
class SessionType{
private $_code_session_type;
private $_name_session_type;
private $_quarter_session_type;
private $_code_lesson;
private $_session_type;
public function __construct($code_session_type,$name_session_type, $quarter_session_type, $code_lesson,$session_type){
$this->_code_session_type = $code_session_type;
$this->_name_session_type = $name_session_type;
$this->_quarter_session_type = $quarter_session_type;
$this->_code_lesson = $code_lesson;
$this->_session_type = $session_type;
}
public function code_session_type(){
return $this->_code_session_type;
}
public function name_session_type(){
return $this->_name_session_type;
}
public function quarter_session_type(){
return $this->_lastname;
}
public function code_lesson(){
return $this->_email_student;
}
public function session_type(){
return $this->_session_type;
}
}
It looks like the function select_session_type2 is returning an array:
$tableau = array();
if ($result->rowcount()!=0) {
while ($row = $result->fetch()) {
$tableau[] = new Sessiontype($row->code_session_type,$row->name_session_type,$row->quarter_session_type,$row->code_lesson,$row->session_type);
}
}
return $tableau;
and you are expecting an object:
$tabsessiontype2=Db::getInstance()->select_session_type2($_POST['sessiontype_name']);
if($tabsessiontype2->session_type()=='X'){
$view='teacher.php';
}

So basically I want to have an Object Class with a bunch of setters that I can manipulate and then convert straight to JSON. In the past I was using an already existing JSON as model(json->object->json). Now I want to just have object->json.
But at the moment I get an empty array when I try to use json_encode.
Also had some trouble with my $index that I'm using because I can have multiple numerical indexes inside "items"
PHP:
<?php
namespace ProjectApi\Models;
use ArrayObject;
use stdClass;
class MagentoInvoice
{
public $capture = true;
public $notify = true;
public function __construct()
{
}
public function setCapture($capture)
{
$this->capture = $capture;
}
public function getCapture()
{
return $this->capture;
}
public function setNotify($notify)
{
$this->notify = $notify;
}
public function getNotify()
{
return $this->notify;
}
public function setItems($itemsCount)
{
$i = 0;
while($i < $itemsCount)
{
$this->items = new stdClass();
$i++;
}
}
public function getItems()
{
return $this->items;
}
public function setProductQty($index, $qty)
{
$this->items->$index->qty = $qty;
}
public function getProductQty($index)
{
return $this->items->$index->qty;
}
public function setProductOrderItemId($index, $id)
{
$this->items->$index->order_item_id = $id;
}
public function getProductOrderItemId($index)
{
return $this->items->$index->order_item_id;
}
}
JSON
{"capture":true,"items":[{"order_item_id":123,"qty":1},{"order_item_id":321,"qty":1}],"notify":true}
$body = new MagentoInvoice();
$body->setCapture(true);
$body->setNotify(true);
if($firstProductId != null && $secondProductId != null)
{
$body->setItems(2);
$body->setProductQty(0, 1);
$body->setProductOrderItemId(0, $firstProductId);
$body->setProductQty(1, 1);
$body->setProductOrderItemId(1, $secondProductId);
}
print_r(json_encode($body));
Hi there still new to PHP and struggling with something really basic and it's frustrating me cause I can't see the error. I have read the PHP manual on passing array of objects.
class Customer{
public $companyId;
public $customerId;
public $name;
public function __construct($companyId,$customerId,$name)
{
$this->companyId = $companyId;
$this->customerId = $customerId;
$this->name = $name;
}
}
class CustomersDB
{
...
/**
* #return Customer[]
*/
public function getCustomers($search_str): array {
$resultObj = array();
$result = NULL;
try {
if (! $this->db) {
die('Database handle not defined') ;
}
if ($search_str && ! empty($search_str)) {
$result = $this->ListCustomers(Utils::COMPANY_ID, $search_str, $this->db);
while ($row = $result->fetch(PDO::FETCH_ASSOC)) {
$_tmp = new Customer($row['CompanyID'],
$row['CustomerID'],
$row['CustomerName']);
// $resultObj.push($_tmp);
$resultObj[] = $_tmp;
}
}
} catch (Exception $e) {
// echo Utils::logMsgtoWeb($e->getTraceAsString());
} finally {
$result = NULL;
}
return $resultObj;
}
}
use Respect\Rest\Routable;
class Customers implements Routable {
/**
*
* Can pass in a partial string to search for a customer
* or pass in an ID for a specific match.
*/
public function get($searchStr){
// header('Content-type: application/json');
$result = $this->custdb.getCustomers($searchStr); // ERRORS HERE
if ($result && ! empty($result)) {
return json_encode( $result);
} else {
return NULL;
}
}
}
I get this error: PHP Recoverable fatal error: Object of class Scheduler\db\CustomersDB could not be converted to string in Customers.php.
Any help would be appreciated.
I don't even know if this is possible but I'm trying to set an optional value to an existing object.
Here is a simplified version of the code I'm trying.
<?php
class configObject {
private $dataContainer = array();
public function set($dataKey, $dataValue) {
$this->dataContainer[$dataKey] = $dataValue;
return TRUE;
}
public function get($dataKey) {
return $this->dataContainer($dataKey);
}
$this->set('someValue', 'foobar');
} //End configObject Class
function getPaginationHTML($c = &$_config) {
$someOption = $c->get('someValue');
// Do other stuff
return $html;
}
$_config = new configObject();
$html = getPaginationHTML();
?>
I'm getting the error:
syntax error, unexpected '&' in
Any help is appreciated, again I'm not sure if it's even possible to do what I'm trying to do so sorry for being a noob.
Thanks
example with the decorator pattern:
class ConfigObject {
private $dataContainer = array();
public function set($dataKey, $dataValue) {
$this->dataContainer[$dataKey] = $dataValue;
return true;
}
public function get($dataKey) {
return $this->dataContainer[$dataKey];
}
}
class ConfigObjectDecorator {
private $_decorated;
public function __construct($pDecorated) {
$this->_decorated = $pDecorated;
}
public function getPaginationHTML($dataKey) {
$someOption = $this->get($dataKey);
// Do other stuff
$html = '<p>' . $someOption . '</p>';
return $html;
}
public function set($dataKey, $dataValue) {
return $this->_decorated->set($dataKey, $dataValue);
}
public function get($dataKey) {
return $this->_decorated->get($dataKey);
}
}
class ConfigFactory {
public static function create () {
$config = new ConfigObject();
return new ConfigObjectDecorator($config);
}
}
$config = ConfigFactory::create();
if ($config->set('mykey', 'myvalue'))
echo $config->getPaginationHTML('mykey');
Note that can easily rewrite ConfigFactory::create() to add a parameter to deals with other types of decoration (or none).
I search for an php function which would do the following process:
class Item{
private $id;
public function __construct($id){
$this->id = $id
}
public function foo(){
return 'Item_'.$this->id;
}
}
my_array = array();
$my_array[] = new Item(1);
$my_array[] = new Item(2);
$results = thefunctionimlookingfor($my_array, 'foo');
//which give :
//$results = {'Item_1', 'Item_2'}
Does anyone knows this function name?
$results = array_map(function(Item $item) { return $item->foo(); }, $my_array);
And if you really need to have that function:
function applyMethod($data, $method) {
return array_map(function($item) use ($method) {
return $item->$method();
}, $data);
}
$result = applyMethod($my_array, 'foo');
I'm getting a class not found error but without the name of the class. I got the code from here
but when I try to run it, it gives the following error..
Fatal error: Class '' not found in C:\Program Files\Apache Software Foundation\Apache24\Apache24\htdocs\framework\library\controller.class.php on line 16
and the following is the controller
<?php
class Controller {
protected $_model;
protected $_controller;
protected $_action;
protected $_template;
function __construct($model, $controller, $action) {
$this->_controller = $controller;
$this->_action = $action;
$this->_model = $model;
include 'model.class.php';//other similar posts suggested this but its not working
$this->$model = new $model;
$this->_template = new Template($controller,$action);
}
function set($name,$value) {
$this->_template->set($name,$value);
}
function __destruct() {
$this->_template->render();
}
}
I'm assuming its the model class which is not being found. The model class code is
<?php
class Model extends SQLQuery {
protected $_model;
function __construct() {
$this->connect(DB_HOST,DB_USER,DB_PASSWORD,DB_NAME);
$this->_model = get_class($this);
$this->_table = strtolower($this->_model)."s";
}
function __destruct() {
}
}
and sqlquery class is
<?php
class SQLQuery {
protected $_dbHandle;
protected $_result;
/** Connects to database **/
function connect($address, $account, $pwd, $name) {
$this->_dbHandle = #mysql_connect($address, $account, $pwd);
if ($this->_dbHandle != 0) {
if (mysql_select_db($name, $this->_dbHandle)) {
return 1;
}
else {
return 0;
}
}
else {
return 0;
}
}
/** Disconnects from database **/
function disconnect() {
if (#mysql_close($this->_dbHandle) != 0) {
return 1;
} else {
return 0;
}
}
function selectAll() {
$query = 'select * from `'.$this->_table.'`';
return $this->query($query);
}
function select($id) {
$query = 'select * from `'.$this->_table.'` where `id` = \''.mysql_real_escape_string($id).'\'';
return $this->query($query, 1);
}
/** Custom SQL Query **/
function query($query, $singleResult = 0) {
$this->_result = mysql_query($query, $this->_dbHandle);
if (preg_match("/select/i",$query)) {
$result = array();
$table = array();
$field = array();
$tempResults = array();
$numOfFields = mysql_num_fields($this->_result);
for ($i = 0; $i < $numOfFields; ++$i) {
array_push($table,mysql_field_table($this->_result, $i));
array_push($field,mysql_field_name($this->_result, $i));
}
while ($row = mysql_fetch_row($this->_result)) {
for ($i = 0;$i < $numOfFields; ++$i) {
$table[$i] = trim(ucfirst($table[$i]),"s");
$tempResults[$table[$i]][$field[$i]] = $row[$i];
}
if ($singleResult == 1) {
mysql_free_result($this->_result);
return $tempResults;
}
array_push($result,$tempResults);
}
mysql_free_result($this->_result);
return($result);
}
}
/** Get number of rows **/
function getNumRows() {
return mysql_num_rows($this->_result);
}
/** Free resources allocated by a query **/
function freeResult() {
mysql_free_result($this->_result);
}
/** Get error string **/
function getError() {
return mysql_error($this->_dbHandle);
}
}
I'm new to PHP and I'm using PHP 5.5.15. I know I should probably switch this to pdo, but i just want to get this working before gettin jiggy with it.
Any help much appreciated
Simple said, you have this function for your controller:
function __construct($model, $controller, $action) {
$this->$model = new $model;
}
You need to give a $model, wich would be the name of a class. You give no name. This is why class "" can not be found.
If we would write this:
$controller = new Controller("mycrazymodel", null, null);
It means:
function __construct($model, $controller, $action) {
//$this->$model = new $model;
$this->$model = new mycrazymodel; //above means this, if $model = "mycrazymodel"
}
So what does this mean for you?
Locate the call of the Controller::__construct method, which typical mean new Controller(...) and make sure, you give the classname as $model parameter.
Take a look at the manual for further information: http://php.net/manual/en/language.namespaces.dynamic.php
