I am using Zend Expressive 2 due to PHP version constraints. If I return variables in step one of pipeline (IndexAction) the variables appear just fine.
If I delegate to the next step (VerifyInputAction) and determine there is an error in the input, I need to return an error to view script. For some reason, it will not take the variables with it that I pass with the template renderer. It will still load the template, just not with the $data array variables.
I'm using Zend View as the template renderer.
My pipeline looks as follows.
IndexAction()
public function process(ServerRequestInterface $request, DelegateInterface $delegate)
{
if ($request->getMethod() !== "POST") {
return new HtmlResponse($this->template->render('app::home-page', ['error' => 'hello']));
} else {
$delegate->process($request);
//return new HtmlResponse($this->template->render('app::home-page'));
}
}
VerifyInputaction()
public function process(ServerRequestInterface $request, DelegateInterface $delegate)
{
$data = [];
$file = $request->getUploadedFiles()['recordsFile'];
$fileType = substr($file->getClientFilename(), strpos($file->getClientFilename(), '.'));
// If file type does not match appropriate content-type or does not have .csv extension return error
if (! in_array($file->getClientMediaType(), $this->contentTypes) || ! in_array($fileType, $this->extensions)) {
$data['error']['fileType'] = 'Error: Please provide a valid file type.';
return new HtmlResponse($this->template->render('app::home-page', $data));
}
$delegate->process($request);
}
Another problem that might be beyond the scope of this question includes, when I make it to the next Action in the pipeline, if I go to render a view script there I get this error...
Last middleware executed did not return a response. Method: POST Path: /<--path-->/ .Handler: Zend\Expressive\Middleware\LazyLoadingMiddleware
I will do my best to provide more code examples, but due to this being an issue at work I might have some problems with that.
Thanks!
