jquery - simple quote escape issue with pdo-php-javascript (ajax) -

-

Here's my problem:

I have a PHP script (one AJAX query from my database with PDO ): 

  ... some code $ myString = $ pdoObject ['field']; ... some code   
 is a single quote in the string: ' 
  Example: this is strange   
 Later in this php script, I have put the string in a long string variable that I send back to my AJAX query:  
  $ wholeString = " ; Td & gt; & lt; span title = '$ MyString' & gt; Some text & lt; / span & gt; & lt; / td & gt; & lt; / tr & gt; ";   
 Then I send it back: json_encode ($ wholeString);  
 In my AJAX query, I just put the result in a jquery field:  
  ... some code success: function (response) {$ ("# myField" ). Html (feedback); } ... Some code   
 always talks tight on the quote:  
  & lt; Tr & gt; & Lt; Td> & Lt; Span title = 'this' & gt; Some text & lt; / Span & gt; & Lt; / Td> & Lt; / Tr & gt;   
 If I try to use htmlentities or htmlspecialchars before putting $ myString in the full string, it does not change anything ... I'm missing out on something. ..  
 Thank you   
 
 
 You basically have an html injection problem. You must use htmlspecialchars () to avoid all html metacars in your text, in which  '  
 
  $ wholeString = "& lt; tr & Gt; & lt; td & gt; & lt; span title = '' Htmlspecialchars ($ myString, ENT_QUOTES) "'& gt; Some text & lt; / Span & gt; & Lt; / Td> & Lt; / Tr & gt; ";   
 As written in your code, you will be born:  
  & lt; tr & gt; ; Td & gt; & lt; span title = 'this is weird' & gt; some text etc ...   
 which will cause the span tag to parsor the browser  
  & lt; span title = 'it' // "single" unknown random characteristic "weird" illegal single quote

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

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
