javascript - jQuery Mobile form submission with signature image -

-

I'm using jQuery signer pad here, with source and demo:

now All this shows the image of your signature when you click, now with the image on the page, how can I submit my form.

I am sending my form to a PDF converter named MPDF using a modified version:

To get an image on PDF, I want to get it from the picture on the page Now what to do, as you click on submitting it, there is no information in dragging that image.

> I am not the most lover in PHP because any help I am learning will be greatly appreciated.

Update Code provided by Thanasus Grammotopolos 

  function fun_submit () {If (isSign) {var canvas = $ ("# canvas") Get (0); Var imgData = canvas.toDataURL (); // To change the code here, do not display the image, it was sent to Server $ .AJX ({type: "POST", url: "script.php", data: {imgBase64: imgData}}. O) {Warning ('Sub-limit'.);}); ClosePopUp (); } And {warnings ('please sign in'); }   
}  
 PHP:  
  & lt ;? Php define ('UPLOAD_DIR', 'up /'); $ Img = $ _POST ['IMGData']; $ Img = str_replace ('data: image / png; base64,', '', $ img); $ Img = str_replace ('', '+', $ img); $ Data = base64_decode ($ img); $ File = UPLOAD_DIR Unicode () '.png'; $ Success = file_put_contents ($ file, $ data); ? & Gt;   
 Still provides a 0kb .png file on the server with nothing on it. Where do I go from here?   
 
 
 You just have to send an image to the server, change your code to:  
  Function fun_submit () {if (isign) {var canvas = $ ("# canvas"). Get (0); Var imgData = canvas.toDataURL (); // To change the code here, do not display the image, it was sent to Server $ .AJX ({type: "POST", url: "script.php", data: {imgBase64: imgData}}. O) {Warning ('Sub-limit'.);}); ClosePopUp (); } And {warnings ('please sign in'); }}

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
