Admin panel of a Q & A Forum

In a Q & A Forum, when a user posts a question, it should be sent to the administrator for approval in case it contains inappropriate content.

In the Pending approvals page only the records with approval=false should be displayed. Below is  the MySQL  statement for retrieval, $sql="SELECT * FROM topics WHERE approval=false"; To know which post was approved we should embed the post_id to the URL.

Creating the Service Provider First step is to create a service provider in Identity Server. This is required because when a client application talks to Identity Server via OAuth 2.0, Identity Server has to identify the client and the incoming traffic. We set this configuration inside the service provider. Login to the Management Console of Identity Server and create a service provi...
