  • Password verification; Is this way of doing it safe?

    - by Camran
    I have a classifieds website, where everybody may put ads of their products. For each classified, the user has to enter a password (so that they can delete the classified whenever they wish). So basically, when somebody wants to delete a classified, they click on the classified, click on the delete button, and enter the pass. I use MySql as a database. I use this code basically: if ($pass==$row['poster_password']) where row[poster_password] is fetched from MySql... What do you think? Thanks

    - by WAC0020
    I am getting the date from my mysql database and that date is correct but when I use the date() function the minute part is stuck a 6 minutes. My mysql is returning 2010-06-15 09:59:18 Then in php I use this code: date('M d,Y H:m A',strtotime($row[4])) ** $row[4] is from my while loop ** When I echo this out I get: Jun 15,2010 9:06 AM I also have tried converting it to unix timestamp in my sql query, does the same thing. I noticed that the hours work and the seconds work but the minutes are stuck at 6. Does anyone have any ideas on what is going on?

  • Grid forms in Rails

    - by KandadaBoggu
    I am trying to create a grid form for a survey question. value1 value2 value3 option 1 x option 2 x option 3 x Each cell in the grid is a radio button and the radio buttons in a row belong to one radio button group. My models: class Question # title has_many :answers end class Answer # name, position, atype(row/col) end I am struggling to come up with a Rails approach for creating such a form. To complicate the issue user can save the semi-completed form and complete it at a later time. What is the best approach for this problem?

  • How can i attach data to a JTA transaction? (or uniquely identify it)

    - by kwyjibo
    I have a getStockQuote() function that will get a current stock quote for a symbol from the stock market. My goal is that within a JTA transaction, the first call to getStockQuote() will fetch a stock quote, but all subsequent calls within the same transaction will reuse the same stock quote (e.g.: it will not try to fetch a new quote). If a different transaction starts, or another transaction runs concurrently, i would expect the other transaction to fetch its own stock quote on its first call. This would be similar to how you can configure JPA providers to only fetch a database row from the database once, and use the cached value for subsequent access to the same database row within the transaction. Does anyone have tips on how this can be achieved?

  • Why can I create a table with PRIMARY KEY on a nullable column?

    - by AlexKuznetsov
    The following code creates a table without raising any errors: CREATE TABLE test( ID INTEGER NULL, CONSTRAINT PK_test PRIMARY KEY(ID) ) Note that I cannot insert a NULL, as expected: INSERT INTO test VALUES(1),(NULL) ERROR: null value in column "id" violates not-null constraint DETAIL: Failing row contains (null). ********** Error ********** ERROR: null value in column "id" violates not-null constraint SQL state: 23502 Detail: Failing row contains (null). Why can I create a table with a self-contradictory definition? ID column is explicitly declared as NULLable, and it is implicitly not nullable, as a part of the PRIMARY KEY. Does it make sense? Edit: would it not be better if this self-contradictory CREATE TABLE just failed right there?

  • why is link generated in YUI javascript failing to render in rails?

    - by pmneve
    Using YAHOO.widget.treeview to generate a table with three levels of data: module, submodule, and detail. If there is an image associated with a detail row the javascript generates a link: "<td><a href=\"/screenshot/show/" + rowData.id + "\">Screenshot</a></td>" that is appended to the html for the row. The url is generated correctly and the link appears. When clicked nothing happens except the word 'Done' appears in the browser status bar. Am calling the very same url from another page that does not use javascript and the screenshot page appears as expected. Here is the controller. class ScreenshotController < ApplicationController def show if @detail.screen_path.length 1 @imagePath = "#{RAILS_ROOT}" + "/private/#{Company.find(@detail.company_id).subdir}/" + "#{Project.find(@detail.project_id).subdir}/screenshot/" + "#{@detail.screen_path}" send_file ( @imagePath, :type = 'image/jpeg', :disposition = 'inline') end end end A sample url: http://localhost:3004/screenshot/show/20854 This code from show.html.erb belonging to the detail model works: <%= link_to 'View', :controller = 'screenshot', :id = @detail.id, :action = 'show' % Any ideas???

  • PHP MySQL Syntax Error 'You have an error in your SQL syntax'

    - by Alec
    I cannot figure out the issue with my code here. I am trying to take info from the table, then subtract 1 second from Current_Time which looks like '2:00'. The problem is, I get: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Current_Time) VALUES('22')' at line 1" I don't even understand where it gets 22 from. Thanks, I really appreciate it. if (isset($_GET['id']) && isset($_GET['time'])) { mysql_select_db("aleckaza_pennyauction", $connection); $query = "SELECT Current_Time FROM Live_Auctions WHERE ID='1'"; $results = mysql_query($query) or die(mysql_error()); while ($row = mysql_fetch_array($results)) { $newTime = $row['Current_Time'] - 1; $query = "INSERT INTO Live_Auctions(Current_Time) VALUES('".$newTime."')"; $results = mysql_query($query) or die(mysql_error()); } }

  • Selecting data from mysql table and related data from another to join them

    - by knittledan
    Ive looked at other questions and answers but still dont understand which brings me here. I have one data base two tables. lets say table1 and table2 from database. I'm looking to grab all the information from table1 and only one column from table2 that coincides with the correct row in table1. Example which I know is wrong: SELECT table1.*, table2.time_stamp FROM table1, table2 WHERE table1.ticket_id=$var AND table1.user_id = table2.user_id Basically select data from table1 then use a value from the selected table to grab the related data from table2 and join them to output them as one mysql_query. Im sure its simple and has been asked before. edit: I dont receive an error. SQL just returns noting. log form of this would be: $sqlResults = mysql_query("SELECT table1.* FROM table1 WHERE table1.ticket_id=$var") while($rowResult = mysql_fetch_array( $sqlResults )) { $userID = $rowResult['user_id']; $sqlResults2 = mysql_query("SELECT table2.time_stamp FROM table2 WHERE table2.user_id=$userID") } I want to combine that into one sql statement so i dont have to hit table2 for every row table1 has

  • Select only the first rows for each unique value of a column in R

    - by dmvianna
    From a dataframe like this test <- data.frame('id'= rep(1:5,2), 'string'= LETTERS[1:10]) test <- test[order(test$id), ] rownames(test) <- 1:10 > test id string 1 1 A 2 1 F 3 2 B 4 2 G 5 3 C 6 3 H 7 4 D 8 4 I 9 5 E 10 5 J I want to create a new one with the first appearance of each id / string pair. If sqldf accepted R code within it, the query could look like this: res <- sqldf("select id, min(rownames(test)), string from test group by id, string") > res id string 1 1 A 3 2 B 5 3 C 7 4 D 9 5 E Is there a solution short of creating a new column like test$row <- rownames(test) and running the same sqldf query with min(row)?

  • Duplicate / Copy records in the same MySQL table

    - by Digits
    Hello, I have been looking for a while now but I can not find an easy solution for my problem. I would like to duplicate a record in a table, but of course, the unique primary key needs to be updated. I have this query: INSERT INTO invoices SELECT * FROM invoices AS iv WHERE iv.ID=XXXXX ON DUPLICATE KEY UPDATE ID = (SELECT MAX(ID)+1 FROM invoices) the proble mis that this just changes the ID of the row instead of copying the row. Does anybody know how to fix this ? Thank you verrry much, Digits //edit: I would like to do this without typing all the field names because the field names can change over time.

  • How can keep track of the index path of a button in a tableview cell?

    - by Jake
    I have a table view where each cell has a button accessory view. The table is managed by a fatchedresults controller and is frequently reordered. I want to be able to press a button and be able to obtain the index path of the pressed button's tableviewcell. I've been trying to get this working for days by storing the row of the button in it's tag, but when the table get's reordered the row becomes incorrect and I keep failing at reordering the tags correctly when a change is made. Any new ideas on how to keep track of the button's cell's index path? Thanks so much for any help.

  • VBA for filtering columns

    - by Ampi Severe
    I have a big database-like sheet, first row contains headers. I would like a subset of rows of this table based on column values. Two issues: 1) VBA-wise I would like to loop through the columns, when the values for all necessary columns all match, copy the entire row into a new sheet. 2) The subset of rows is based on a list. This should be the first column to be looped through. For example I want all rows where the value in column A is equal to one of the values in my list. Is there any possibility to autofilter strings based on a list (column) of strings? EDIT Thanks to @Doug Glancy the autofiltering works now, so I've removed my (horrible) code and issue 1 is solved.

  • Gridview making a column invisable

    - by flyersun
    Hi I have a grid view which is dynamically generated via C# using a DataSet. I'm passing a row ID field (from the database) to the grid view, as this is required when a user clicks to edit a records. However I don't want the user to be able to view the column. I have tried the following but it doesn’t seem to work? Could anyone suggest a way to hide the column or a better way of attaching the information to the grid view row so it can be used at a later stage. c# DataColumn ColImplantCustomerDetailsID = new DataColumn(); ColImplantCustomerDetailsID.ColumnName = "Implant ID"; ColImplantCustomerDetailsID.DataType = typeof(int); ColImplantCustomerDetailsID.Visable = false; <-- visable doens't work here. asp.net

  • find lowest neighbor matlab

    - by user1812719
    I am trying to write a function [offset,coffset]=findLowNhbr(map) that for each pixel in a map finds the eight neighbors to the pixel, and returns two matrices with both the row and column offsets to the lowest neighbor (uses the numbers -1, 0 and 1). Border pixels are given 0 offsets for both the row and column, since they do not have neighbors. Here is what I think the general plan for this function should be: For each point, find the eight nearest neighbors. If the neighbor is lower than the point, return -1 If the neighbor is at the same elevation as the point, return 0 If the neighbor is higher than the point, return +1 Store these offsets in two matrices. I am at a complete loss as to where to start, so any advice or questions are welcome!

I mean that in an i-th row of this matrix an i-th column (of a real matrix) is stored. There is an example: i-th row: 1 2 3 4 (in the file). That means that the real matrix has an i-th column: (1 2 3 4)(is transposed). I need to save this matrix in a natural way (by rows) in a new file, which I will then open with FileReader and display with TextArea. Do you know, how to do that? If so, please help =)
