PHP - How To Access Method Object In Base Class From Derived Class? Error In My Solut
I have mysqli object in Database class base:
[color=]database class:[/color] class Database { private $dbLink = null; public function __construct() { if (is_null($this->dbLink)) { // load db information to connect $init_array = parse_ini_file("../init.ini.inc", true); $this->dbLink = new mysqli($init_array['database']['host'], $init_array['database']['usr'], $init_array['database']['pwd'], $init_array['database']['db']); if (mysqli_connect_errno()) { $this->dbLink = null; } } } public function __destruct() { $this->dbLink->close(); } } Class derived is Articles where I use object dBLink in base (or parent) class and I can't access to mysqli methods (dbLink member of base class): Articles class: require_once ('./includes/db.inc'); class Articles extends Database{ private $id, .... .... $visible = null; public function __construct() { // Set date as 2009-07-08 07:35:00 $this->lastUpdDate = date('Y-m-d H:i:s'); $this->creationDate = date('Y-m-d H:i:s'); } // Setter .... .... // Getter .... .... public function getArticlesByPosition($numArticles) { if ($result = $this->dbLink->query('SELECT * FROM articles ORDER BY position LIMIT '.$numArticles)) { $i = 0; while ($ret = $result->fetch_array(MYSQLI_ASSOC)) { $arts[$i] = $ret; } $result->close(); return $arts; } } } In my front page php I use article class: include_once('./includes/articles.inc'); $articlesObj = new articles(); $articles = $articlesObj->getArticlesByPosition(1); var_dump($articles); [color=]Error that go out is follow[/color] Notice: Undefined property: Articles::$dbLink in articles.inc on line 89 Fatal error: Call to a member function query() on a non-object in articles.inc on line 89 If I remove constructor on derived class Articles result don't change Please help me Similar TutorialsI have these two classes: Code: [Select] <?php class A { private $id; public function __construct() { $this->id = '11111'; } public function getProperty($prop) { return $this->$prop; } }?> Code: [Select] <?php class B extends A { private $message = "Nope, can't see it"; public function __construct() { parent::__construct(); $this->message = "Yep, I can see it"; } }?> I tried this, but it just outputs the id (the first call) Code: [Select] $class = new B; echo $class->getProperty('id'); echo $class->getProperty('message'); Why is that? I thought I could use a parent method on a child property.. *EDIT* Using a public or protected visibility on the message property gets me the output I expect...how come? I have the code as given below: <?php class ABC { function printValue() { print("This value shall be printed" . $this->x); } } class BCD extends ABC { private $x=10; } $bcd=new BCD; $bcd->printValue(); ?> But when I try to access printValue function from the paren class it gives me error... Fatal error: Cannot access private property BCD::$x in /var/www/html/trainingweb/modules/test/TestAtitProblem.php on line 5 As the public method of ABC would be extended to BCD, it shall have access to its own member. please help... Ok. I know you can pass the object of a class as an argument. Example: class A { function test() { echo "This is TEST from class A"; } } class B { function __construct( $obj ) { $this->a = $obj; } function test() { $this->a->test(); } } Then you could do: $a = new A(); $b = new B($a); Ok so that's one way i know of. I also thought that you could make a method static, and do this: (assuming class A's test is 'static') class B { function test() { A::test(); } } But that is not working. I'd like to know all possible ways of accomplishing this. Any hints are appreciated. thanks If a class has a constructor but also has a static method, if I call the static method does the constructor run so that I can use an output from the constructor in my static method? --Kenoli Hi Can you call Class A's methods or properties from Class B's methods? Thanks. Hello , I have a made a PHP website where users signup and send their Date of Birth and gets an OTP on their email after signup. The OTP is recieved but when we enter the OTP this problem occurs QuoteError!

I don't know what I can do now , Please try to give me the solutions as soon as possible. Thanks I have two classes: ## Admin.php <?php class Admin { public function __construct() { include("Config.php"); } /** * deletes a client * @returns true or false */ function deleteClient($id) { return mysql_query("DELETE FROM usernames WHERE id = '$id'"); } } ?> ## Projects.php <?php class Projects { public function __construct() { include("Config.php"); $this->admin = $admin; $this->dataFolder = $dataFolder; } /** * Deletes a project * @returns true or false */ function deleteProject($id) { $root = $_SERVER['DOCUMENT_ROOT']; $theDir = $root . $this->dataFolder; $sql = mysql_query("SELECT * FROM projectData WHERE proj_id = '$id'"); while ($row = mysql_fetch_array($sql)) { $mainFile = $row['path']; $thumb = $row['thumbnail']; if ($thumb != 'null') { unlink($theDir . "/" . substr($thumb,13)); } unlink($theDir . "/" . substr($mainFile,13)); } $delete = mysql_query("DELETE FROM projectData WHERE proj_id = '$id'"); $getDir = mysql_query("SELECT proj_path FROM projects WHERE id = '$id'"); $res = mysql_fetch_array($getDir); rmdir($theDir . "/" . $res['proj_path']); return mysql_query("DELETE FROM projects WHERE id = '$id'"); } } ?> How can I call deleteProject() from within Admin.php? Hi people! class FirstOne{ public function FunctionOne($FirstInput){ //do stuff and output value return $value1; } } Then:- class SecondOne{ public function FunctionTwo($AnotherInput){ //do stuff and output value return $value2; } } What I want to know is this, if I want to use FunctionOne() in Class SecondOne do I do it like this:- (Assume as I have instantiated the first class using $Test = new FirstOne(); ) class SecondOne{ function SecondedFunction(){ global $Test; return $Test->FunctionOne(); } public function FunctionTwo($AnotherInput){ //do stuff and output value return $value2; } public function FunctionThree(){ //some code here $this->Test->SecondedFunction();<--I think as I can omit the $this-> reference } } My point is: Do I have to do it this way or is there way of having this done through __construct() that would negate the need for a third party function? I have a version working, I just think that it is a little convoluted in the way as I have done it, so I thought I would ask you guys. Any help/advice is appreciated. Cheers Rw Hey, I'm trying to create an object oriented webpage, with just some basic features, like creating a user, logging in, admin restricted pages. However I'm stuck at this point.

Hi everyone, I get this error: Catchable fatal error: Object of class Category could not be converted to string The code: public static function list_all_cat_names() { $result_array = self::find_by_sql("SELECT name FROM ".self::$table_name); return !empty($result_array) ? array_shift($result_array) : false; } $categories = Category::find_all(); foreach ($categories as $cats): echo $cats; endforeach; Where could be the problem? I have the following script: <?php $tijd[] = '2012-05-23T02:00:00'; $date = new DateTime($tijd[0]); echo $date; ?> However it is not working and resulting in: Quote Catchable fatal error: Object of class DateTime could not be converted to string in time3.php on line 7 I think to solve this issue, I have to convert $tijd[0] into a string. Right? If this is correct, how do I do that? I've been trying to solve this for a while now, but still haven't had any luck. What I'm trying to do is this: $class = new BaseClass; $var = $class->load("subclass")->subclass_function("info"); Thanks in advance Ayon
My script has 3 classes (that are relevant to this discussion): DB, User and Validate. They are all in independent files and loaded automatically, when required, by an autoloader.
The error messages I am getting a Any pointers as to what I am doing wrong, or what I should be doing, would be most welcome. I found class on the net, and i am having a bit of a problem to understand how does update method works. Here is the code: Code: [Select] public function update() { global $database; // Don't forget your SQL syntax and good habits: // - UPDATE table SET key='value', key='value' WHERE condition // - single-quotes around all values // - escape all values to prevent SQL injection $attributes = $this->sanitized_attributes(); $attribute_pairs = array(); foreach($attributes as $key => $value) { $attribute_pairs[] = "{$key}='{$value}'"; } $sql = "UPDATE ".self::$table_name." SET "; $sql .= join(", ", $attribute_pairs); $sql .= " WHERE id=". $database->escape_value($this->id); $database->query($sql); return ($database->affected_rows() == 1) ? true : false; } I have form like this to deal with update: Code: [Select] <form action="index.php?page=languages" enctype="multipart/form-data" method="POST"> <?php foreach($language as $lang){ ?> <input type="hidden" name="MAX_FILE_SIZE" value="<?php echo $max_file_size; ?>" /> <label>Jezik</label><input type="text" size="50" name="language" value="<?php echo $lang->lang; ?>" /><br> <input type="hidden" name="id_lang" value="<?php echo $lang->id_lang; ?>" /> <label>Slika</label><input type="file" name="image"><?php echo "<img src=\"../images/"; echo $lang->image; echo "\">"; ?> <br> <label>Pozicija</label><input type="text" name="pozicija" value="<?php echo $lang->pozicija; ?>" size="2" /></p> <br> <input type="submit" name="submit_update" value="Unesi"> <?php } ?> </form> and code to start the function: Code: [Select] if(isset($_POST['submit_update'])) { $language = new Jezik(); $language->update(); } What next??? Using this locally works fine: $html = $name::add_content($name, $html); but i get the double colon error whe using it live. $name is a name of a valid class. What could throw this error when it works locally? Hi I have a problem with the following: Code: [Select] <?php class ClassA { public $propertyClassName = "ClassB"; public function methodClassName() { return "ClassB"; } } class ClassB { public function bmethod() { echo "great!"; } } //works $a = new ClassA(); $b = new $a->propertyClassName(); $b->bmethod(); //doesn't work $a = new ClassA(); $b = new $a->methodClassName(); $b->bmethod(); ?> Of course I could do Code: [Select] <?php $a = new ClassA(); $className = $a->methodClassName(); $b = new $className; $b->bmethod(); ?>but isn't there a way to do this without saving the method's return to a variable? Thanks in advance flolam I am having problem with calling class member from with the function in that class. <?php class board { function __construct () { $num_sheep_init=20; $num_lion_init=2; $board_value=array(0=>'', 1=>'', 2=>'', 3=>'', 4=>'', 5=>'', 6=>'', 7=>'', 8=>'', 9=>'', 10=>'', 11=>'', 12=>'', 13=>'', 14=>'', 15=>'', 16=>'', 17=>'', 18=>'', 19=>'', 20=>'', 21=>'', 22=>'', 23=>'', 24=>''); $random_array_value=array (0,1,2,3,4,5,7,9,10,11,13,14,15,17,19,20,21,22,23,24); $selected_index=array(); $randd=array(); $countt=0; } function init_board () { $this->board_value['6']="S"; Above is part of the code where i am having problem. It says that it can not access empty property //$this->board_value['6']="S"; HI everyone! So basically I have this class called Login and another class classed Reports. They both extend a main class called OOP. I'm trying to get classes now and in the future, when I add on, to access that class so that way I dont have to create a new object everytime I need to do that. Plus I know I dont want to rely on calling another class inside of one class. Here is an example The Super Class class OOP{ public function Login($pointer){ $Login->{$pointer}(); } public function Reports($pointer){ $Reports->{$pointer}() } } Login Class class Login extends OOP{ public function userLogin($user, $pass){ //Login code here //if error occurs, send it to Reports super::Reports(Error()); } } Reports Class class Reports extends OOP{ public function Error(){ //Send an error here } } Here is how I think I would call the class if a user was to login. $OOP = new OOP(); $OOP->Login(userLogin($user, $pass)); So now when I need to call any class I should be able to, correct? If you are confused about the top, then think of it this way: I am trying to create a class to where I can call or reference to ANY object now or in the future so I can add on and call that class from another class. Thank you for any help. Well in the class UserValidator I have a public method validate(), which checks the validation type and then calls specific private methods to execute the validation script. It gets a bit tricky here since the method validate() has to decide what private method to call. I am thinking about using call_user_func_array(), the script currently looks like this below: Code: [Select] public function validate(){ // The core method validate, it sends requests to different private methods based on the type if(empty($this->type)) throw new Exception('The validation type is empty, something must be seriously wrong...'); if(is_array($this->type) and !is_array($this->value)) throw new Exception('Cannot have scalar value if the type is an array.'); if(!is_array($this->type) and is_array($this->value)) throw new Exception('Cannot have scalar type if the value is an array.'); // Now we are validating our user data or input! $validarray = array("register", "login", "password", "session", "email", "reset", "profile", "contacts", "friends"); foreach($this->type as $val){ $method = "{$val}validate"; if(in_array($val, $validarray)) call_user_func_array(array($this, $method), array()); } } The method to execute depends on the validation type passed into the validator class, so it is somewhat like a dynamic function call. The problem is, well, I am not sure if I am using call_user_func_array() properly. I read it from php manual that it needs to accept a class instance, but there is no such instance inside a class method so I use $this in the argument. Is this the correct way of using call_user_func_array()? If not, how am I supposed to do this? thanks. |
