jquery - process post data from ajax post with php -

-

I created a simple Ajax request with jquery ajax to post a string for the php script (php newbie) is.

AJAX: 

  $ Ajax ({url: "php / server.php", type: "post", data: imgname, contentType: false, processData: wrong, error: function (xhr, textStatus, thrownError) {console.log (thrownError);} , Full: function (jqXHR) {console.log ("yes", jqXHR)}});

PHP 

  & lt ;? Php $ ajaxData = gettype ($ _ POST ['data']); Echo $ ajaxData; ? & Gt;

Problem:

I get a state 200 OK and in the request header, I can see that my string has been posted. But the information is empty;

notice with notification: Undefined index: C: \ xampp \ htdocs \ webwiese \ dragdropUpload \ php \ fileserver.php in uploadfilename 2

If I echo out a simple string "per hand" then it works fine, but I posted ajax to my data How can I "catch" from? THX

You can "hold" your data from the PHP page. You will then return the necessary headings for the AJAX page.

c# - LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method -

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...

ruby on rails - Add fingerprint to old paperclip attachments -

-
I use paperclip for attachments on my model. I recently added a fingerprint for the attachment, it works fine with new attachments, but this does not add to the old ones, because of this, because of the problem of reprocessing attachments to add a new style to me Is happening, because the paperclip tries to find the attachment with fingerprint and not one of the attachments. Is there a way to add fingerprint to old attachments? The error is that I have reprocessed old attachments: Erro :: Anoint: There is no such file or directory - / TMP / paperclrip-repris20140422-1036- nl9gxk [edit] Have you tried? $ rake paperclip: refresh class = Model_Name_Goes_Here [/ edit] If you do not have too many images The simplest way, I can think: Dir.foreach ('/ path / to / dir / that / contains / old / images').
