MichielW Posted March 28, 2019 Share Posted March 28, 2019 Hello! I'm pretty new to Processwire and I'm trying to retrieve data from inside a class, but nothing seems to work ? With the posted approach (including the namespace) the error message says it can't find the class GetContent. Wihtout the namespace it gaves a 'call to a member function get() on null'. Also using $this-> or not doesn't seem to make a difference. When putting $pages->get("/info)->title; outside the class, it does work (but that's obviously not what I want). The "/info" is hardcoded, just to isolate the problem. I pasted the error messages at the bottom. === CODE === <?php namespace Processwire; require_once("../defaultpwsite/index.php"); class GetContent { public function getTitle($req_page) { $page_title = $this->pages->get("/info")->title; return $page_title; } public function getContent($req_page) { $page_content = $this->pages->get("/info")->textblock; return $page_content; } } === ERROR 1 (NOT USING NAMESPACE) Fatal Error: Uncaught Error: Call to a member function get() on null in /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/php/model/getcontent.model.php:26 Stack trace: #0 /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/php/view/page.basesite.htmldoc.view.php(21): GetContent->getContent('home') #1 /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/php/controller/page.controller.php(37): PageContent->__construct('home') #2 /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/php/controller/main.controller.php(42): PageController->showResponse() #3 /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/index.php(25): MainController->handleRequest() #4 {main} thrown (line 26 of /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/php/model/getcontent.model.php) === ERROR 2 (USING NAMESPACE) Fatal Error: Uncaught Error: Class 'GetContent' not found in /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/php/view/page.basesite.htmldoc.view.php:21 Stack trace: #0 /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/php/controller/page.controller.php(37): PageContent->__construct('home') #1 /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/php/controller/main.controller.php(42): PageController->showResponse() #2 /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/index.php(25): MainController->handleRequest() #3 {main} thrown (line 21 of /Applications/mampstack-7.0.31-0/apache2/htdocs/simplesite/php/view/page.basesite.htmldoc.view.php) Link to comment Share on other sites More sharing options...
Autofahrn Posted March 28, 2019 Share Posted March 28, 2019 Hello @MichielW and welcome to the forum and PW. The global PW variables (like $pages) are not directly accessible out of a class, you'll have to go through the wire() method or wire() function. $page_content = $this->wire('pages')->get("/info")->textblock; or $page_content = wire('pages')->get("/info")->textblock; Depending on your use context it probably would be better to hand over the $page via parameter (or cache its value in your class instance), to reduce re-fetching the same content from database with each call.

MichielW Posted March 29, 2019 Author Share Posted March 29, 2019 Thanks a lot! I finally got it running. It also seemed the namespaceing on the top didn't work out for me, placing in front of 'wire()' did the job: $page_title = \ProcessWire\wire('pages')->get($this->req_page)->title; Link to comment Share on other sites More sharing options...
