mysql - Accessing Data VIA PDO within a function - PHP -

-

I am quite new to PHP, so I apologize in advance for posting any bad code. .

I have created a basic membership system for a fitness bootcamp. I have two SQL table- "member" and "payment".

I have created a table, and using a loop, I can display all the members. Now, I want to be able to check that the member paid the payment using the checkpay ().

This function sees the payment table whether payment is made for that member ID near that line, within the current month and year.

Even when payment is entered in the payment table, the user still shows up as unpaid. 

  Function check payment ($ member, $ month, $ year) {global $ db; $ Payment = "Select * FROM 'payment' WHERE member_id =: memberid"; $ Result = $ db- & gt; Ready ($ payment); $ Result-> Beyond Parm (': Member', $ Member, PDO :: Paramax); $ Result-> Beyond Parm (': Month', $ Month, PDO :: Paramatti); $ Result-> Beyond Parm (': year', $ year, PDO: Paramatti); Return result-> Fetch column (); } Code   
 Here is the code to display:  
  foreach ($ db-> query ('SELECT * FROM' members') As $ line) {$ checkpayment = checkpayment ($ line ['id'], 10,2014); If (! $ Checkpayment) {$ status = "danger"; $ Paid = "unpaid"; } And {$ status = "success"; $ Paid = "paid"; } Echo & lt; Tr class = "'. $ Status.'" & Gt; & Lt; TD & gt; '. $ Line ['id']. '& Lt; / Td> & Lt; TD & gt; '. $ Line ['first_name'] '& lt; / TD & gt; & Lt; TD & gt; '. $ Line ['last_name']. '& Lt; / Td> & Lt; TD & gt; '. $ Paid '& lt; / TD & gt; & Lt; TD & gt; '. $ Line ['program'] '& lt; / TD & gt; & Lt; / TR & gt; '; }   
 However, even when a payment line is present, members are still not paid ...   
 
 
 If you are using the  ready  function, then you should use  execute ()  As far as I know. Try below, if not working, then I will update.  
 You can see some details about the check payment form ($ member, $ month, $ year) {code> execute ()   
  Global $ db; $ Payment = "Choose * Payments from WHERE member_id =: Member"; $ Result = $ db- & gt; Ready ($ payment); $ Result-> Beyond Parm (': Member', $ Member, PDO :: Paramax); $ Result-> carry about (); // ADD This line returns $ result-> Fetch column (); }

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
