Date Feb 2011 Posts 31 [RESOLVED] Fatal error: Call to protected method I'm just starting out OOP in PHP and using a tutorial I found here... I'm having a bit of trouble with the inheritance bit as when I run the code I get the following Code: Fatal error: Call to protected method person::change_name() from context '' in C:\Program Files (x86)\EasyPHP-5.3.6.1\www\index.php on line 77 In the following code I fatal error call to undefined method wc_product_simple was under the impression protected access modifiers allowed the parent and child classes to access methods, so I'm not sure why the new object stefan of the parent type is unable to access the change_name() method. Code: name= $persons_name; } function get_name(){ return $this->name; } //can be used by child class.. protected function change_name($new_name){ if (name !="Jimmy Two Guns"){ $this->name=strtoupper($new_name); } } /*fucntions can have access modifiers too.. thus this can not be called outside this object*/ private function get_pin(){ return $this->pin; } } /*using 'extends' to utilize inheritance*/ class employee extends person{ function __construct($employee_name){ //notice we have access to person->set_name() //because employee is just an extension of person $this->change_name($employee_name); } //we overide method from parent class by naming it the same protected function change_name($new_name){ if ($new_name == "Stefan Sucks"){ $this->name = $new_name; } //using object::method() to access an objects method

Question: is there a way to make the closure "inherit" the class context? php class closures currying share|improve this question edited Jun 11 '15 at 13:54 Brian Tompsett - 汤莱恩 3,091132775 asked Jan 25 '11 at 21:46 fabio 73721126 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote accepted Apparently not natively. This manual note suggests a rather cumbersome way of using reflection and a wrapper class to give closures private/protected access functionality though. share|improve this answer answered Jan 25 '11 at 21:52 BoltClock♦ 384k949351047 I checked that and it seems to work but nobody will ever use it because obviously it costs too much in terms of performance.

Class members declared public can be accessed everywhere. Members declared protected can be accessed only within the class itself and by inherited classes. Members declared as private may only be accessed by the class that defines the member. Property Visibility Class properties must be defined as public, private, or protected. If declared using var, the property will be defined as public. Example #1 Property declaration browse to the main page [index.php] I get the following message: Fatal error: Call to protected method HTML_QuickForm2_Renderer_Array::exportMethods() from context 'HTML_QuickForm2_Renderer_Proxy' in /var/www/html/piwik/libs/HTML/QuickForm2/Renderer/Proxy.php on line 113 What can I do ? Please help! I am using PHP 5.1.6. Thank you in advance ! vipsoft 2010-07-22 02:37:28 UTC #2 I've opened a ticket. http://dev.piwik.org/trac/ticket/1495 earwax 2010-07-22 02:45:01 UTC #3 Yeah, same problem here. I'm using CentOS 5.5. The upgrade from 0.6.3 to 0.6.4 was smooth. I liked the new look and everything, and then when I logged out, BAM! The error showed up and I can't get back in. vipsoft 2010-07-22 04:18:16 UTC #4 It looks we ran into a PHP bug. http://bugs.php.net/bug.php?id=37632 The workaround is as follows: 1) cd piwik/libs/HTML/QuickForm22) edit the following files: Element.phpElement/InputFile.phpElement/InputImage.phpElement/InputCheckbox.phpElement/Button.phpElement/Date.phpElement/Select.phpElement/InputSubmit.phpElement/Static.phpRenderer.phpRenderer/Array.phpRenderer/Default.phpContainer.phpNode.php 3) wherever you see any of these function declarations/definitions: abstract protected function updateValue() protected function updateValue() protected function exportMethods() change "protected" to "public", e.g., abstract public function updateValue() public function updateValue() public function exportMethods() tatacalu 2010-07-23 17:37:11 UTC #5 Thank you !!! One question though: if Quickform2 doesn't support PHP < v5.2, what will you do ? Will you ship a customized version of Quickform ? Cheers ! vipsoft 2010-07-23 20:04:55 UTC #6 Yes, for as long as Piwik supports PHP 5.1.x, we'll be distributing a modified version of HTML_QuickForm2.
