php - Fetch value from database into dynamically added row -

-

I'm new to PHP programming, now I'm making a program for billing system. The table is created and by adding the row dynamically to the table, it works fine. Now I want to add value to the database in the dynamically added row, please tell me how to add value. Here is my code form 

  & lt; form style = "margin-left: 200px; padding: 10px; background: yellow; width: 500px;" Action = "bill.fp" method = "post" name = "transaction" id = "transaction" & gt; & Lt; Span style = "color: black" & gt; Receipt Number: & lt; / Span & gt; & Amp; Nbsp; & Amp; Nbsp; & Amp; Nbsp; & Amp; Nbsp; & Amp; Nbsp; & Amp; Nbsp; & Amp; Nbsp; & Lt; Input type = "text" name = "no RCPT" id = "no RCPT" /> gt; & Lt; / Br & gt; & Lt; / Br & gt; & Lt; Label = "student name" & gt; & Lt; Span style = "color: black" & gt; Customer's Name: & lt; / Span & gt; & Lt; / Label & gt; & Lt; Select name = "st_name" id = "st_name" & gt; & Lt; Option value = "" & gt; Select ..  / Options & gt; & Lt; / Select & gt; & Lt; / Br & gt; & Lt; / Br & gt; & Lt; Label = "academic year" & gt; & Lt; Span style = "color: black" & gt; Academic year: & lt; / Span & gt; & Amp; Nbsp; & Amp; Nbsp; & Lt; / Labels & gt; & Lt; Select name = "arad_yyyyyyyyy" id = "arad_yure" & gt; & Lt; Option value = "" & gt; Select ..  / Options & gt; & Lt; / Select & gt; & Lt; / Br & gt; & Lt; / Br & gt; & Lt; label = "item name" & gt; & Lt; Span style = "color: black" & gt; Item name: & lt; / Span & gt; & Amp; Nbsp; & Amp; Nbsp; & Amp; Nbsp; & Amp; Nbsp; & Amp; Nbsp; ; & Amp; Nbsp; & Nbsp; & Nbsp; & Amp; Nbsp & lt; / Labels & gt; & Lt; Choose name = "item_name" id = "item_name" & gt; & Lt; Option value = "" & gt; Select ..  / Options & gt; & Lt; / Select & gt; & Lt; Input type = "button" name = "addItem" id = "addItem" value = "add item" /> & Lt; / Br & gt; & Lt; / Br & gt; & Lt ;! - & lt; Div id = "items1" & gt; & Lt; B & gt; & Lt; / B & gt; & Lt; / Div & gt; - & gt; & Lt; Table id = "item" limit = "2" width = "400px" cellpadding = "4" cellpaction = "1" & gt; & Lt; TR & gt; & Lt; -! & Lt; Th & gt; Sr.No. & lt; / Th & gt; - & gt; & Lt; Th & gt; Item name & lt; / Th & gt; & Lt; Th & gt; Unit cost & lt; / Th & gt; & Lt; Th & gt; Quantity & lt; / Th & gt; & Lt; Th & gt; Total & lt; / Th & gt; & Lt; / TR & gt; & Lt; Tbody & gt; & Lt; / Tbody & gt; & Lt; / Table & gt; & Lt; / Form & gt;   
 and here  JQUERY   
  var cnt = 2; ($ ('($' '(' # AddItem ') Click' & lt; tr & gt; & lt; td & gt; '+ cnt +' & lt; / td & gt; Item tr '). Td>' + cnt + '& lt; / td> & lt; td & gt; & lt; input type = "text" name = "txtbx' + cnt + '" value = "'+ Cnt +'" "gt; & lt; / td> & lt; / tr & gt; '); cnt ++;});   
 So please tell me, how can I add the data name and the dynamically added row to the unit price?  
 Thanks in advance.  
 
 
 I assume that you have the SQL database, what is this taste of SQL ?  
 In a way you can do that using an Ajax call to capture database information, and then use it in your dynamically created table.  
 Your Ajax might look like this:  
  $ Ajax ({url: "http: // locationofyourdbhook",}) .done (function) {if (console & amp; console ('& lt; tr & gt; & lt; td & gt;' + data After cnt + ' & lt; TD & gt;' + data.cnt + '($ "' ('# item tr'). & Lt; / td & gt; & lt; Td> Input  & lt; / Tr>); cnt ++;}});

python - Writing Greek in matplotlib labels, titles -

I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

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 ...
