Accessing PageTitleLanguage when bootstrapped

[ralberts]

Hi folks,

I'm looking to return results from PW in an Ajax call, but I'm not sure if I'm going about this the right (or preferred) way.

I created a script in /htdocs/public/ajax/affiliates.php, which is called using Ajax.

The script itself bootstraps Processwire and returns JSON for all affiliates. It looks something like this:

<?php

require_once '../../index.php';

$data['markers'] = array();

$markers = array();
$affiliates = wire()->pages->find("template=affiliate");
foreach ($affiliates AS $affiliate)
{
	$marker['latitude'] = $affiliate->mapmarker->lat;
	$marker['longitude'] = $affiliate->mapmarker->lng;
	$marker['title'] =  $affiliate->title;	

	$data['markers'][] = $marker;
}

print(json_encode($data));

The problem here is that $affiliate->title returns an object (LanguagesPageFieldValue), instead of the actual string I would expect it to do.

I'm not sure where I'm going wrong here. I may have to manually set the language, call the title in a another manner, or just use a different approach alltogether. Any help is much appreciated

title->getLanguageValue is the method you are looking for. Something like this should work:

<?php

require_once '../../index.php';

$data['markers'] = array();

$markers = array();

$affiliates = wire()->pages->find("template=affiliate");

foreach ($affiliates AS $affiliate)

{

$marker['latitude'] = $affiliate->mapmarker->lat;

$marker['longitude'] = $affiliate->mapmarker->lng;

foreach (wire('languages') as $language) {

$marker['title_' . $language->name] = $affiliate->title->getLanguageValue($language);;

}

$data['markers'][] = $marker;

}

print(json_encode($data));

Hi Interrobang,

Thanks for your response. That might work, assuming I can fetch the language of the current user in my bootstrapped script. I cannot test this right now, but wire()->user->getLanguage() combined with your suggestion should do the trick.

Thanks again!

Made a small workaround by adding the users language to the ajax request to get this to work:

<?php

require_once '../../index.php';

$data['markers'] = array();

$markers = array();
$affiliates = wire()->pages->find("template=affiliate");

$language = wire()->languages->get("default");
if (isset($_GET['language'])) {
	$language = wire()->user->language = 1010;
}

foreach ($affiliates AS $affiliate) {
	$marker['latitude'] = $affiliate->mapmarker->lat;
	$marker['longitude'] = $affiliate->mapmarker->lng;
	$marker['title'] = $affiliate->title->getLanguageValue($language);

	$data['markers'][] = $marker;
}

print(json_encode($data));

It feels a bit hacky and I guess there is a better way to achieve this. So any input is more then welcome, but for now I'm happy with this solution

You might want to move this into a PW template file (the exact code, minus the require_once at the top). This would ensure things are output formatted and you can take advantage of PW determining the language for you and such. Though the way you are doing it is just fine, but since you are bootstrapping PW output formatting is not enabled by default. You can enable output formatting for your $affiliate pages, so that you are dealing with formatted values. In your case, that would mean $title would be a string rather than an object. 

$affiliate->of(true); 

You may also want to add a header before outputting your JSON:

header("Content-Type: application/json");

Thanks for the response Ryan.

I already figured out that moving the code to a template file solved my problem. Enalbing output formatting is a valuable hint though, thanks!

Btw, most objects in ProcessWire can also just be typecast to strings, which usually gives you the intended value. This would be the case for a LanguagePageFieldValue object too. 

$value = (string) $object;

Is it possible to get the user language on a page called with AJAX, that has PW bootstrapped?

I am using this code:

$language = $wire->user->language;

but it doesn't seem to work.
