PHP - I Found A Php 'extends' Bug....
This code works without problems:
<?php
namespace NamespaceA;
class A extends \NamespaceB\B {}
namespace NamespaceB;
class B {}
But why the following code cause Fatal error: Class 'NamespaceB\B' not found in ...file?
<?php
namespace NamespaceA;
class A extends \NamespaceB\B {}
namespace NamespaceB;
class B extends \NamespaceC\C {}
namespace NamespaceC;
class C {}
And this code also works without problems:
<?php
namespace NamespaceA;
class A extends \NamespaceB\B {}
namespace NamespaceC;
class C {}
namespace NamespaceB;
class B extends \NamespaceC\C {}
Without any namespace, also Fatal error: Class 'B' not found in ...file:
<?php
class A extends B {}
class B extends C {}
class C {}
Works without problems:
<?php
class A extends B {}
class B {}
And yes everything is in the same PHP file....
Similar TutorialsI was wondering if there was a class that I could extend that extends the main class in php. For example all of the classes that I am creating will extend the core class or will be extending a class that extends from the core class. However if the class doesnt exist then it will throw an error. What I would like to do is be able to handle this error instead of just throwing the error so I was hoping that there was a class that I could extend the core class from to handle these errors. This way I can use the magic method __get() to handle the error. If there is another way to go about this please let me know so that I can look into that solution. hi phpfreaks I have an class that is called "connDatabase" what I want to do with it is either extend it or implement it. But I don't know which one to use. The other issue I have is say class "a" has three vars that the that the construct needs to obstantiate and "connDatabase" needs three of its own. How do I obstantiate? thanks for any help If I have a base class MyBase: Code: [Select] class MyBase { public $user_id = NULL; public function __construct() { $this->user_id = "justin"; } } Then I have a class which inherits the base class MyClass: Code: [Select] class Test extends MyBase { public static function get_user_id() { echo parent::$user_id; } } Finally calling it: Code: [Select] echo Test::get_user_id(); First question, do I have to create an instance of MyBase, or when Test extends MyBase will it instanciate it automatically and call the MyBase constructor? Second, I am getting the error: PHP Fatal error: Access to undeclared static property: MyBase::$user_id I am making login system using codeigniter. When I run my code i get this error. Code: [Select] The requested URL /ci_login/user/login was not found on this server. here is my code so far user.php file which is in controller folder Code: [Select] <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class User extends CI_Controller { function __construct() { parent::__construct(); } function index() { } function login() { if($this->form_validation->run() == FALSE) { $this->load->view('view_login'); } else { echo "Successfull"; } } } view_login.php file which is in view folder Code: [Select] <html> <head> <title>Login</title> </head> <body> <h1>Please Login!</h1> <p>Use the login form below to login.</p> <div id="login_form"> <?php echo form_open(base_url(). 'user/login' ) ?> <label>Username:</label> <div> <?php echo form_input(array('id' => 'username', 'name' => 'username')); ?> </div> <label>Password:</label> <div> <?php echo form_password(array('id' => 'password', 'name' => 'password')); ?> </div> <div> <?php echo form_submit(array('name' => 'submit'),'Login'); ?> </div> <?php echo form_close(); ?> </div> </body> </html> help please how can I solve this error? I think this is a PHP topic rather than Javascript. Can anyone tell me why this code cannot find the page (404 Not Found) Code: [Select] <?php if ("{$row['passState']}" == 0) { ?> <script language="javascript" type="text/javascript" > <-- var newwindow; function popupgo() { newwindow = window.open('check.php?quizTitle=<?php ".urlencode($quizTitle)."; ?>','_blank', 'scrollbars=yes,top=0,left=0,width='+screen.width+',height='+screen.height); if (window.focus) {newwindow.focus()} } //--> </script> <?php echo "<form><input type='button' onClick='popupgo()' value='Popup'></form>"; } ?>when this test code works fine? Both files are PHP. Code: [Select] <?php ?> <head> <script language="javascript" type="text/javascript" > <-- var newwindow; function popupgo() { newwindow = window.open('check/check.php?quizTitle=<?php '.urlencode($quizTitle).'; ?>','_blank', 'scrollbars=yes,top=0,left=0,width='+screen.width+',height='+screen.height); if (window.focus) {newwindow.focus()} } //--> </script> </head> <body> <form> <input type="button" onClick="popupgo()" value="Popup"> </form> </body> <?php ?> I'm trying to show my friend my website and it's not letting him or me view it.

Maybe I have too many questions but it's first time when I use PHP and don't understand too much. Help is appreciated, again. Thanks! I readed about if, else... still can't solved. Fatal error: Call to undefined function curl_init() in C:\(etc etc...) Now I know the usual causes for a problem like this, but they are not solving anything. Yes, extension=php_curl.dll is uncommented in the php.ini file. Yes, phpinfo() displays the php.ini file I have been editing as the Loaded Configuration File. Yes, extension_dir is set correctly in my php.ini file (other extensions work). Yes, php_curl.dll exists in my ext/ folder. No, phpinfo() does not display anything about cURL, anywhere Where else can I look to possibly fix this? Hello, I am trying to implement a simple script that ZIPs up a text file. The problem is that I don't think the ZIPArchive is available on my server. Here is an example of my code: Code: [Select] <?php $zip = new ZipArchive(); $filename = "./PJR.v2.zip"; if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) { exit("cannot open <$filename>\n"); } if ($handle = opendir('WORKDIR')) { while (false !== ($entry = readdir($handle))) { if ($entry != "." && $entry != "..") { $zip->addFile($entry); } } closedir($handle); } $zip->close(); ?> When I run it from the command line, I get Code: [Select] PHP Fatal error: Class 'ZipArchive' not found in /users/albert/zip_POC.v2.php on line 2 This is the version info on my server: Code: [Select] php -v PHP 5.1.6 (cli) (built: Nov 12 2008 11:22:53) Copyright (c) 1997-2006 The PHP Group Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies Is there a way that I can install that class even though I am not the 'root' user?? Hi This is a strange one, and I'm not sure whats going on here. I've tried googling the answer to no avail. Basically, I'm writing a Wordpress plugin, and here's my setup: install.php has a class called 'two_install' The main plugin file code snippet: Code: [Select] // Installation require(plugin_basename('installer.php')); // Initiate installation class $twp_install = new twp_install; This results in this on activation: Fatal error: Class 'twp_install' not found in path-on-server\wp-content\plugins\twitter_parser\twitter_parser.php on line xx Anyone got any ideas? Just a note, there is definitely a class called 'twp_install' in installer.php! Thanks in advance Hi New to php code, been trown in at the deep end.

Thanks I apologize, I thought I was posting in php. I assume you will move it. So I'm trying to mess around with the HttpRequest class and it can't be found. I looked it up and it said I have to enable the extension in the php.ini file but I couldn't find the php_http.dll extension that the website said I should be able to find and un-semicolon. What exactly is a PHP HttpRequest? It seems like a few languages have this functionality. What is possible with the PHP HttpRequest, do I need other languages to get, send or display data through HttpRequest? Thanks for any help. Hello. I have a system worked out where I have 2 columes for friends in my database (login_info). One of these is requests and the other is friends. Each request/friend is seperated with a underscore (_). I use the explode() function to seperate the friends/requests into a array. My only problem is I want to display the a different text if the user has sent a requests or is already friends with the user. I tried to do this using the array_search() function and converting it into a boolean (with the boolean cast). It doesn't seem to be working. Code: [Select] <?php $query = mysql_query('SELECT friends, requests FROM login_info WHERE user = \' ' .$userget .'\''); $friend = mysql_fetch_assoc($query); $req = explode('_', $friend['requests']); $friends = explode('_', $friend['friends']); if((bool)array_search($userget, $friends) && (bool)checkarray($userget, $req)) { echo '<a href="?p=add&user='.$userget .'"> Add As Friend </a>'; } if((bool)array_search($userget, $req)) { echo 'Friend Request Pending'; } if((bool)array_search($userget, $friends)) { echo $userget .'Is Your Friend' .$user_log .'!'; } ?> Any help? My Project: Online school note sharing for my university. How: You upload your note(s) get credits and with those credits buy other notes to download. Problem: Whats to stop someone from uploading a note they have downloaded. Security: Currently I have all notes go through an approval system where a staff member views the note sees if it is a legit note then approves it granting the user credits and making the note downloadable. So does anyone have any theories about how I could stop someone from uploading a file that they have uploaded before or have downloaded? timestamps on files md5checksums anything I need to find a way to fix this error and I have no idea. Hi guys, I am trying to calculate hours a person works by calculating the values of text fields in a form. However, when I load the page I get "Class 'times_counter' not found. Here is the calculation code" if(isset($_POST['calculate']) != ""){
class times_counter {
private $hou = 0;
private $min = 0;
private $sec = 0;
private $totaltime = '00:00:00';
public function __construct($times){
if(is_array($times)){
$length = sizeof($times);
for($x=0; $x <= $length; $x++){
$split = explode(":", @$times[$x]);
$this->hou += @$split[0];
$this->min += @$split[1];
$this->sec += @$split[2];
}
$seconds = $this->sec % 60;
$minutes = $this->sec / 60;
$minutes = (integer)$minutes;
$minutes += $this->min;
$hours = $minutes / 60;
$minutes = $minutes % 60;
$hours = (integer)$hours;
$hours += $this->hou % 24;
$this->totaltime = $hours.":".$minutes;
}
}

}
$times = array(

$thdiff->format('%H:%I'),
$fridiff->format('%H:%I'),
$satdiff->format('%H:%I'),
$sundiff->format('%H:%I'),
);
$counter = new times_counter($times);
I had this on an old project, which I no longer have but it worked then. Any ideas? |
