php - Select option not passing values -

-

My selection options are not passing I do not know why this is not working, it will be appreciated, but I do not know what's going on.

HTML / PHP 

  if (isset $ _POST ['submit'])) {$ name = release ($ _ POST ['name'])? Trim ($ _ POST ['name']): '';   date  gt; & lt; l & gt; LHA & lt; / th & gt; & lt; th & gt; ax & lt; / th & gt; & lt; Lt; th & gt; ls  gt; update & lt; / th> & lt; / tr & gt;;; $ Sql ​​= "SELECT * data from where name = '$ name' date from date"; "; $ Sth = $ pdo- & gt; Query ($ sql); While ($ line = $ sth-> fetch ()) {$ car = $ line ['car']; Echo "& lt; form action = '' method = 'post' & gt;"; Echo "& lt; tr & gt;"; Echo "& lt; td & gt;" . $ Line ['name'] "& Lt; / td & gt;"; Echo "& lt; td & gt; & lt; input type = 'text' name = 'car' placeholder = '' $ line ['car']. '' Value = '' & gt; & lt; / td & Gt; "; Echo "& lt; td & gt; & lt; input type = 'text' name = 'car' placeholder = '' $ line ['night']. '' Value = '' & gt; & lt; / td & Gt; "; Echo "& lt; td & gt; & lt; input type = 'text' name = 'car' placeholder = ''. $ Line ['citid']. '' Value = '' & gt; & lt; / td & Gt; "; Echo "& lt; td & gt; & lt; input type = 'text' name = 'car' placeholder = ''. $ Line ['date']. '' Value = '' & gt; & lt; / td & Gt; "; In this example, " & lt; input type = 'text' name = 'car' placeholder = '' $ line ['LH']. '' Value = '' & gt; & lt; / td & Gt; "; Echo "& lt; td & gt; & lt; input type = 'text' name = 'car' placeholder = ''. $ Line ['AAS']. '' Value = '' & gt; & lt; / td & Gt; "; Echo "& lt; td & gt; & lt; input type = 'text' name = 'car' placeholder = '' $ line ['ls']. '' Value = '' & gt; & lt; / td & Gt; "; Echo "& lt; input type = 'hidden' name = 'pid' value = ''. $ Line ['PID']. "'/ / Gt;"; Copy "& lt; td & gt; & lt; input type = 'submit' name = 'submit' value = ''. $ Line ['PID']. ' '/ / Gt; & Lt; / Td> "; Echo" & lt; / Tr & gt; "; echo" & lt; / Form & gt; ";} resonates" & lt; / Table> "; $ Pdo = NuLL;} Then {echo" Choose a user ";}? & Gt;   
 HTML form  
  
  Select name = "name" id = "name">      
 
 
 Due to this, you have no value in your option tag  
 try it  
   action = "" method = "Post" & gt; Select name = "name" id = "name" & gt; & lt ;? php foreach ($ line as $ data):? & Gt; & lt; option value = "& Lt ;? Php = $ row ["user_name"]? & Gt; "& gt; Php echo $ row [" user_name "]? & Gt; & lt; / option & gt; & lt ;? php endforeach? & Gt; & lt; / select & gt; & Lt; input type = "submit" value = "submit" & gt; & lt; / form & gt;   
 and use it php tags in its better manner, its Instead of what you are using at this time  
  $ name = isset ($ _ POST ['name'])? Trim ($ _ POST ['name']): ''; < Lt ;? Php echo $ row ["user_name"]? & Gt; // I do not know why you have this line here   
 to display more results  
  & lt ;? php echo $ name; & gt;

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...
