php - Returning search results for different language -


i have simple site dropdown has primary options apple, bananas, pears etc, user selects option , clicks search , site returns results article primary tag matches option, it's done using simple primary_tag=primary_option condition. in english, user has come along , wants install copy of site , change apple, bananas, pear arabic language apple becomes تفاحة in dropdown , in articles. gets no search results although has tagged articles تفاحة rest of site stays same , has utf-8 character encoding believe supports arabic text. why not working , can work?

edit 1 - sample code

$primary_option = preg_replace('/^-|-$|[^-a-za-z0-9 ]/', '', $_get['primary_option']);

then

'key' => 'primary_tag', 'value' => $primary_option, 'compare' => 'like'

then

if ($results->have_posts())

just realised preg_replace causing issue.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
