php - Get the Category Name in WordPress - efficient or "bad" code? -

-

This is a question that is more about code best practices: 

  $ cat_name = get_the_category () [0] - & gt; Name;   
 Instead of doing so with some wars, in some steps:  
  $ cat = get_the_category (); $ Cat_name = $ cat [0] - & gt; Name;   
 Is this considered bad behavior? Or is it problematic in any way? If so, why? Then, my question is about the code, not the result.   
 
 
 I can say that it depends on you that you have php set to display a notice , And if you care about the undefined offset notice, here's the problem (IMO), see the beginning of the function:  
  function get_the_category ($ id = false) {$ categories = get_the_terms ($ id , 'category'); If (! $ Ranges || is_wp_error ($ ranges)) $ categories = array ();   
 You can see that if there are no categories or if there is an error, "the law" is empty. Perform a quick test ...  
  & lt ;? Php $ categories = array (); Resonate $ ranges [0] - & gt; Name;   
 get us  
  notice: undefined offset: notice on line 5 in test.php: trying to get non-object property in test.php If the ($ cat) is $ {cat_name = $ cat [0] - & gt; Name; }

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

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...
