php - Prepared statement returns 0 instead of 1, why? -

-

What's the problem with this case? Why do I get 0 instead of 1? If I run a query from phpMyAdmin then it works fine. If $ ($ stmt = $ mysqli- & gt; ready (select "WHERE user name = and password =?")) {$ Input ['hold'] = md5 ($ Input ['pass']. $ Config ['salt']); $ Stmt- & gt; Dam_param ("ss", $ input ['user'], $ input ['hold']); $ Stmt- & gt; Store_result (); $ Stmt- & gt; Executed (); If ($ stmt-> num_rows & gt; 0) {// set session variable $ _SESSION ['username'] = $ input ['user']; Header ("location: member.fp"); // if we have results, redirect it again}

I have no solution , But some comments that are too big for a comment.

The code shown by you will set the session if the result is zero, or fails, as well as when the number of rows is zero, there is no error check to see that the code is executing expectedly Yes or No.

You should check the errors, also try running it with a hard coded SQL statement, which you have verified and verified using PHPMyAdmin's mysql command line client.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
