  • Data not entering the table

    - by Luke
    //loop through usernames to add to league table for ($i = 0; $i < count($user); $i++) { //set some new variables in an array $username = $user[$i]; $squad = $team[$i]; //add details to league table if ( $username != "Ghost") { $database->addUsersToLeagueTable($username, $squad); } } I use this code to add to the league table, the following is more code: function addUsersToLeagueTable($username, $squad) { $q = "INSERT INTO `$_SESSION[comp_name]` ( `user` , `team` , `home_games_played` , `home_wins` , `home_draws` , `home_losses` ,`home_points, `home_goals_for` , `home_goals_against` , `away_games_played` , `away_wins` , `away_draws` , `away_losses` , `away_points` , `away_goals_for` , `away_goals_against` ) VALUES ( '$username', '$squad', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0')"; return mysql_query($q, $this->connection); } Can you see any obvious reason why this isn't happening? Thanks

    - by Red Hyena
    I have an enum Fruit defined as: object Fruit extends Enumeration { val Apple, Banana, Cherry = Value } Now printing values of this enum, on Scala 2.7.x gives: scala> Fruit foreach println line1$object$$iw$$iw$Fruit(0) line1$object$$iw$$iw$Fruit(1) line1$object$$iw$$iw$Fruit(2) However the same operation on Scala 2.8 gives: scala> Fruit foreach println warning: there were deprecation warnings; re-run with -deprecation for details Apple Banana Cherry My question is: How is the method toString in Enumeration in Scala 2.8 is implemented? I tried looking into the source of Enumeration but couldn't understand anything.

  • Xpath help function

    - by NA
    Hi i have a document from which i am trying to extract a date. But the problem is within the node along with the date their is some text too. Something like <div class="postHeader"> Posted on July 20, 2009 9:22 PM PDT </div> From this tag i just want the date item not the Posted on text. something like ./xhtml:div[@class = 'postHeader'] is getting everything. and to be precise, the document i have is basically a nodelist of this elements for eg i will get 10 nodes of these elements with different date values but to be worse the problem is sometime inside these tags some random other tags also pops us like anchors etc. Can i write a universal expath which will just get the date out of the div tag?

  • Function to set an auth_token

    - by john mossel
    In my form I have a hidden field: <input type="hidden" name="auth_token" value="<?php echo $auth_token; ?>"> This value is also stored in a session and a variable: $_SESSION['auth_token'] = hash('sha256', rand() . time() . $_SERVER['HTTP_USER_AGENT']); # TODO: put this in a function $auth_token = $_SESSION['auth_token']; When the form is submitted the two values are compared. It's a basic form token. Should this be made into two functions or just one when refactored? set_form_token() and get_form_token(), get_form_token() returning the session value, then I can compare it in my main code. What is the proper way of doing this?

  • Flattening hash into string in Ruby

    - by fahadsadah
    Is there a way to flatten a hash into a string, with optional delimiters between keys and values, and key/value pairs? For example, print {:a => :b, :c => :d}.flatten('=','&') should print a=b&c=d I wrote some code to do this, but I was wondering if there was a neater way: class Hash def flatten(keyvaldelimiter, entrydelimiter) string = "" self.each do |key, value| key = "#{entrydelimiter}#{key}" if string != "" #nasty hack string += "#{key}#{keyvaldelimiter}#{value}" end return string end end print {:a => :b, :c => :d}.flatten('=','&') #=> 'c=d&a=b' Thanks

  • Easy way to apply a function to an array

    - by alex
    I am aware of array_walk() and array_map(). However when using the former like so (on an old project) it failed array_walk($_POST, 'mysql_real_escape_string'); Warning: mysql_real_escape_string() expects parameter 2 to be resource, string given. So I went with this slightly more ugly version foreach($_POST as $key => $value) { $_POST[$key] = mysql_real_escape_string($value); } So why didn't the first way work? What is the best way to map values of an array to a function?

  • writing structs and classes to disk

    - by Phenom
    The following function writes a struct to a file. int btwrite(short rrn, BTPAGE *page_ptr) { long addr; addr = (long) rrn * (long) PAGESIZE + HEADERSIZE; lseek(btfd, addr, 0); return (write(btfd, page_ptr, PAGESIZE)); } The following is the struct. typedef struct { short keycount; /* number of keys in page */ int key[MAXKEYS]; /* the actual keys */ int value[MAXKEYS]; /* the actual values */ short child[MAXKEYS+1]; /* ptrs to rrns of descendants */ } BTPAGE; What would happen if I changed the struct to a class, would it still work the same? If I added class functions, would the size it takes up on disk increase?

  • Check if exists, if so, update by 1++, if not insert

    - by Scarface
    Hey guys quick question, I currently have an insert statement $query= "INSERT into new_mail VALUES ('$to1', '0')"; where fields are username, and message_number Currently what I would do to check if the entry exists, is do a select query then check the number of rows with mysql_num_rows (php). If rows==1 then I get the current message_number and set it equal to $row['message_number']++1. Then I update that entry with another query. Is there an easier way to do all this in just mysql with just one query (check if exists, if not insert, if so update message_number, increase by 1)?

  • [R] how do I quickly group the time column in a dataframe into intervals?

    - by Derek
    Hi, Assuming in R, I have a data.frame with the first column representing the time (as POSIXct). The rest of the columns (e.g., columns 2) are numeric data. I would like to group time into 3-minute intervals. Each interval will the the average of values that falls into that particular interval. Right now, I have a for-loop that iterates through the time column and generate the interval on the fly. I am wondering if there's a more elegant way to accomplish the same thing? Thanks in advance.

  • autocomplete-like feature with a python dict

    - by tipu
    In PHP, I had this line matches = preg_grep('/^for/', array_keys($hash)); What it would do is it would grab the words: fork, form etc. that are in $hash. In Python, I have a dict with 400,000 words. It's keys are words I'd like to present in an auto-complete like feature (the values in this case are meaningless). How would I be able to return the keys from my dictionary that match the input? For example (as used earlier), if I have my_dic = t{"fork" : True, "form" : True, "fold" : True, "fame" : True} and I get some input "for", It'll return a list of "fork", "form", "fold"

  • php multidimensional array if loop

    - by user1091558
    I have a multidimensional array like this array[value][1][1] Now i would like to implement if loop like this if ($value = array[value][1][1]) { echo "It works"; } Now it works if i assign the values like [1][1],[2][1]. Is it possible to compare the whole array. I mean if the array looks like array[value][1][1],array[value][2][1],..........,array[value][n][1] It works should be echoed. I tried like this. if ($value = array[value][][]) { echo "It works"; } But its not working. Can anyone give me the correct syntax?

  • Create numbers within an array that add up to a set amount

    - by RussellDias
    I'm fairly new to PHP - programming in general. So basically what I need to accomplish is, create an array of x amount of numbers (created randomly) who's value add up to n: Lets say, I have to create 4 numbers that add up to 30. I just need the first random dataset. The 4 and 30 here are variables which will be set by the user. Essentially something like x = amount of numbers; n = sum of all x's combined; create x random numbers which all add up to n; $row = array(5, 7, 10, 8) // these add up to 30 Also, no duplicates are allowed. I need the values with an array. I have been messing around with it sometime, however, my knowledge is fairly limited. Any help will be greatly appreciated. Cheers

  • which type is best for three radiobuttons?

    - by Manog
    Maybe you consider this question trivial but im just curious what is your opinion. I have three radiobuttons. "Show blue", "Show red" and "Show all". I did it with nullable boolean. There is collumn in database where blue is 0 and red is 1 so in metode i have to translate bool to int to compare those values (i do it in c#).Of course it works, but i wonder if it is the best solution. And question is wich type is best in this case? nullable bool, int, or maybe string?

  • PHP: report table with date gaps

    - by Daniel
    Hi. I have a table in DB which contains summaries for days. Some days may not have the values. I need to display table with results where each column is a day from user selected range. I've tried to play with timestamp (end_date - start_date / 86400 - how many days in report, then use DATEDIFF(row_date, 'user_entered_start_date') and create array from this indexes), but now I've got whole bunch of workarounds for summer time :( Any examples or ideas how to make this correct? P.S. I need to do this on PHP side, because DB is highly loaded.

  • Best way to support large dropdowns

    - by JustAProgrammer
    Say I have a report that can be restricted by specifying some value in a dropdown. This dropdown list references a table with 30,000 records. I don't think this would be feasible to populate a dropdown with! So, what is the best way to provide the user the ability to select a value given this situation? These values do not really have categories and even if I subdivided (by having some nesting dropdown situation) by the first letter of the value, that may still leave a few thousand entries. What's the best way to deal with this?

  • IE7 Negative value cuts off half the element - bug?

    - by Yammi
    I've relatively positioned one of the elements with negative 'top' and 'left' values, the negative 'left' value actually takes the element outside of the 'body' width, this seems fine in all browsers apart from IE7 where it just cuts it off. establi.sh I thought it might be that weird bug where if it's outside the parent container then you have to set a z-index but that didn't work, then I thought it might be the hasLayout bug but trying to fix that didn't work. I'm not an expert on IE browsers so need some help. I'm thinking IE7 might be choking as the negative left value actually takes it outside the body? Thanks

  • Knowledge mining using Hadoop.

    - by Anurag
    Hello there, I want to do a project Hadoop and map reduce and present it as my graduation project. To this, I've given some thought,searched over the internet and came up with the idea of implementing some basic knowledge mining algorithms say on a social websites like Facebook or may stckoverflow, Quora etc and draw some statistical graphs, comparisons frequency distributions and other sort of important values.For searching purpose would it be wise to use Apache Solr ? I want know If such thing is feasible using the above mentioned tools, if so how should I build up on this little idea? Where can I learn about knowledge mining algorithms which are easy to implement using java and map reduce techniques? In case this is a wrong idea please suggest what else can otherwise be done on using Hadoop and other related sub-projects? Thank you

  • One Database Field to Hold Survey Answer

    - by yar
    Skipping the question of whether this is bad design (and the question of why I would want/need to do this), I'm just wondering if my 'math' is right... I have n things that need to be put in order (n is always less than 5): thing1 thing2 thing3 ... and I'd like to store these results in a single integer for thing. My initial thought is that (obviously the code will not look like this): thing = thing1 * 1 + thing2 * 2 + thing3 * 4 + thing5 * 8 will always give me a unique value, and that any value for thing will always translate back to its values for thing1...thingn. Is this correct?

  • Mystery in Ruby sinatra

    - by JVK
    I have the following Sinatra code: post '/bucket' do # determine if this call is coming from filling out web form is_html = request.content_type.to_s.downcase.eql?('application/x-www-form-urlencoded') # If this is a curl call, then get the params differently unless is_html params = JSON.parse(request.env["rack.input"].read) end p params[:name] end If I call this using Curl, params has values, but when this is called via a web form, then params is nil and params[:name] has nothing. I spent several hours figuring out why it happens and asked help from other people, but no one could really find out what is going on. One thing to note is, if I comment out this line: params = JSON.parse(request.env["rack.input"].read) then params has the correct value for "web-form" posting. Actually, the goal is to get the params value if this code is being called by CURL call, so I used: params = JSON.parse(request.env["rack.input"].read) but it messed up the web-form posting. Can anyone solve this mystery?
