  • PHP Regex Question

    - by oyerli
    Hi, I am developing an application using PHP but I am new to regular expressions, I could not find a solution to my problem. I want to replace all occurences of #word with a link, i have written a preg_match for this: $text=preg_replace('~#([\p{L}|\p{N}]+)~u', '<a href="/?aranan=$1">#$1</a>', $text); The problem is, this regular expression also matches the html character codes like &#039; and gives corrupt output. I need to exclude the words starting with &# but i do not know how to do that using regular expressions. Thanks for your help.

  • Question regarding parent/child relationships with dynamically generated checkboxes using jquery

    - by Jeff
    I have a form of checkboxes, that is dynamically generated based on the users content. Sections of checkboxes are broken up by categories, and each category has projects within. For database purposes, the category values have checkboxes, that are hidden. IF a category has sub items that have checkboxes that are checked, THEN the category checkbox is checked as well. I have gotten this working ok using the JQuery .click(), but I can't figure out how to do it when the page loads. Here is my code for when a checkbox is actually clicked: $(".project").click(function() { if($(this).is(":checked") && $(this).hasClass("project")) { $(this).parent().parent().children(':first').attr('checked', true); }else if(!$(this).parent().children('.project').is(":checked")){ $(this).parent().parent().children(':first').attr('checked', false); } }); Now when I am editing the status of these boxes (meaning after they have been saved to the db) the category boxes are not showing up as checked even though their children projects are checked. What can I do to make it so that my category box will be checked at load time if that category's child is checked? Part of the problem I think is with the dynamically changing parent child setup, how can I find the parent box in order to have it checked? Thanks!

  • Twitter Search API Question

    - by supermogx
    I'm using the twitter search API to get twitter posts based on some keywords, using AND and OR keyword. It works OK, but I seem to get problems using hashtags... For example : Not returning any results : http://search.twitter.com/search.json?q="%23ipad+AND+%23ipod"+OR+"%23joke+AND+%23funny"&rpp=100&callback=? Returning results : http://search.twitter.com/search.json?q="ipad+AND+ipod"+OR+"joke+AND+funny"&rpp=100&callback=? But there's results with #ipod AND #ipad because when I search only for #ipod, I can see a lot of posts with both hashtags. Example : http://search.twitter.com/search.json?q=%23ipad&rpp=100&callback=? P.S. %23 = # Any idea?

  • Statistics Question: Kernel Smoothing in R

    - by James Thompson
    I have data of this form: x y 1 0.19 2 0.26 3 0.40 4 0.58 5 0.59 6 1.24 7 0.68 8 0.60 9 1.12 10 0.80 11 1.20 12 1.17 13 0.39 I'm currently plotting a kernel-smoothed density estimate of the x versus y using this code: smoothed = ksmooth( d$resi, d$score, bandwidth = 6 ) plot( smoothed ) I simply want a plot of the x versus smoothed(y) values, which is ## Heading ## However, the documentation for ksmooth suggests that this isn't the best kernel-smoothing package available: This function is implemented purely for compatibility with S, although it is nowhere near as slow as the S function. Better kernel smoothers are available in other packages. What other kernel smoothers are better can these smoothers be found?

  • MySQL: Question about SELECT WHERE AND/OR

    - by Andrew
    I'm trying to write a query that returns the same result from three different events, but I think I am doing it wrong. I can run my query against one event ID and it works. How can I select all three? Here's what I have so far: SELECT * FROM `Registrations` WHERE `Role` = "Attendee" AND `RegistrationStatus_ID` = "1" AND `DigSignature` IS NULL AND `Event_ID` = "147" OR `Event_ID` = "155" OR `Event_ID` = "160"

  • Quick, Beginner C++ Overloading Question - Getting the compiler to perceive << is defined for a spec

    - by Francisco P.
    Hello everyone. I edited a post of mine so I coul I overloaded << for a class, Score (defined in score.h), in score.cpp. ostream& operator<< (ostream & os, const Score & right) { os << right.getPoints() << " " << right.scoreGetName(); return os; } (getPoints fetches an int attribute, getName a string one) I get this compiling error for a test in main(), contained in main.cpp binary '<<' : no operator found which takes a right-hand operand of type 'Score' (or there is no acceptable conversion) How come the compiler doesn't 'recognize' that overload as valid? (includes are proper) Thanks for your time.

  • Basic Hibernate question using and sql query

    - by Aerosteak
    Hello Sorry if this is basic but I cannot find the solution anywhere. I have an java Object ‘Person’ with 3 properties firstname,lastname and username. I have an Oracle Store procedure returning a Resultset with the 3 column. All works fine for that. Now I have another StoreProcedure that will only return firstname and lastname but not username. I get the following error : « could not read column value from result set username. » Hibernate tries to fetch the username property from the resultset. If I remove the property username, then it works. Do I have to Create a Special Pojo for Each type of resultset or can I tell Hibernate what to map for each result set? Please help.

  • Design question - loading info from DB

    - by eriks
    I need to build a class that will represent a row in some table in DB (lets say the table is 'Subscriber' and so is the class). I can have the class Subscriber which constructor receives the Objectkey of subscriber, retrieves info from DB and initializes its members. I add another class - SubscriberLoader which have a static method 'LoadSubscriber'. This method will receive the subscriber objectkey, retrieve info from DB, crate a Subscriber object and initialize its members. Subscriber constructor will be private and SubscirberLoader will be friend class of Subscriber - this way, client could build a Subscriber only using the loader. which of the two in better? any other suggestions?

  • Notepad++ Question

    - by Shane
    I would like a hotkey to Save All in Notepad++ then switch to the browser and refresh the page. I have to do this thousands of times a day and doing the Save All hotkey, then Alt-Tab to the right window, then F5 to refresh again and again, there must be a better solution? I am open to switching editors if there is another that can do this. I have tried using run commands but the problem is although it allows you to make something like [firefox.exe "current file"], if you come down to wanting to open it at a web address like localhost because it needs to run server side, then you have to manually specify the other part of the string, like [chrome.exe "custom var(web address) / filename"] and it always opens a new tab, then creates lots of clutter. Also, if you are editing an include file then it will try to open that instead of the page you want to see when you use the run command, a refresh would be the only realistic method I can think of using.

  • A F# tail-recursive question

    - by ksharp
    Recently, I'm learning F#. I try to solve problem in different ways. Like this: (* [0;1;2;3;4;5;6;7;8] -> [(0,1,2);(3,4,5);(6,7,8)] *) //head-recursive let rec toTriplet_v1 list= match list with | a::b::c::t -> (a,b,c)::(toTriplet_v1 t) | _ -> [] //tail-recursive let toTriplet_v2 list= let rec loop lst acc= match lst with | a::b::c::t -> loop t ((a,b,c)::acc) | _ -> acc loop list [] //tail-recursive(???) let toTriplet_v3 list= let rec loop lst accfun= match lst with | a::b::c::t -> loop t (fun ls -> accfun ((a,b,c)::ls)) | _ -> accfun [] loop list (fun x -> x) let funs = [toTriplet_v1; toTriplet_v2; toTriplet_v3]; funs |> List.map (fun x -> x [0..8]) |> List.iteri (fun i x -> printfn "V%d : %A" (i+1) x) I thought the results of V2 and V3 should be the same. But, I get the result below: V1 : [(0, 1, 2); (3, 4, 5); (6, 7, 8)] V2 : [(6, 7, 8); (3, 4, 5); (0, 1, 2)] V3 : [(0, 1, 2); (3, 4, 5); (6, 7, 8)] Why the results of V2 and V3 are different?

    Hello, I am new at java. I am doing the following: Read from file, then put data into a variable. checkToken = lineToken.nextToken(); processlinetoken() } But then when I try to process it... public static void readFile(String fromFile) throws IOException { BufferedReader reader = new BufferedReader(new FileReader(fromFile)); String line = null; while ((line=reader.readLine()) != null ) { if (line.length() >= 2) { StringTokenizer lineToken = new StringTokenizer (line); checkToken = lineToken.nextToken(); ......

  • Complex orderby question (entity framework)

    - by PFranchise
    Ok, so I will start by saying that I am new to all this stuff, and doing my best to work on this project. I have an employee object, that contains a supervisor field. When someone enters a search on my page, a datagrid displays employees whose name match the search. But, I need it to display all employees that report to them and a third tier of employees that report to the original employee's underlings. I only need three tiers. To make this easier, employees only come in 3 ranks, so if rank==3, that employee is not in charge of others. I imagine the best method of retrieving all these employees from my employee table would be something like from employee in context.employees where employee.name == search || employee.boss.name == search || employee.boss.boss.name == search But I am not sure how to make the orderby appear the way I want to. I need it to display in tiers. So, it will look like: Big Boss Boss underling underling Boss underling Boss Boss Big Boss Like I said, there might be an easier way to approach this whole issue, and if there is, I am all ears. Any advice you can give would be HIGHLY appreciated.

  • Code refactoring c# question around several if statements performing the same check

    - by James Radford
    I have a method that has a load of if statements that seems a bit silly although I'm not sure how to improve the code. Here's an example. This logic was inside the view which is now in the controller which is far better but is there something I'm missing, maybe a design pattern that stops me having to check against panelCount < NumberOfPanelsToShow and handling the panelCount every condition? Maybe not, just feels ugly! Many thanks if (model.Train && panelCount < NumberOfPanelsToShow) { panelTypeList.Add(TheType.Train); panelCount++; } if (model.Car && panelCount < NumberOfPanelsToShow) { panelTypeList.Add(TheType.Car); panelCount++; } if (model.Hotel && panelCount < NumberOfPanelsToShow) { panelTypeList.Add(TheType.Hotel); panelCount++; } ...
