  • First programming language: PHP, Ruby, Python?

    - by Victor
    I've been a Web developer for over 5 years and am looking to start building more complex Web apps. Currently, I know HTML/CSS/Javascript but I feel it's time to start learning something else. I work with a lot of applications based on PHP. I created a vBulletin forum on my own time and I would definitely want to build off of that since it has gained a bit of popularity. I also work with Wordpress quite often. All of the software I work with tends to be based on PHP but I hear a lot of people say Ruby or Python is better. Since I'm starting out, I really don't care which one I learn but I want to start right. Any recommendations for someone with HTML/CSS/Javascript knowledge but wants to branch out?

  • Advice/suggestions for my first project PHP Classes

    - by Philip
    Hi guys, Any advice is welcome! I have a very limited understanding of php classes but below is my starting point for the route I would like to take. The code is a reflection of what I see in my head and how I would like to go about business. Does my code even look ok, or am I way off base? What are your thoughts, how would you go about achieving such a task as form-validate-insertquery-sendmail-return messages and errors? Please try and keep your answers simple enough for me to digest as for me its about understanding whats going on and not just a copy/paste job. Kindest regards, Phil. Note: This is a base structure only, no complete code added. <?php //======================================= //class.logging.php //======================================== class logging { public $data = array(); public $errors = array(); function __construct() { array_pop($_POST); $this->data =($this->_logging)? is_isset(filterStr($_POST) : ''; foreach($this->data as $key=> $value) { $this->data[$key] = $value; } //print_r($this->data); de-bugging } public function is_isset($str) { if(isset($str)) ? true: false; } public function filterStr($str) { return preg_match(do somthing, $str); } public function validate_post() { try { if(!is_numeric($data['cardID'])) ? throw new Exception('CardID must be numeric!') : continue; } catch (Exception $e) { return $errors = $e->getCode(); } } public function showErrors() { foreach($errors as $error => $err) { print('<div class="notok"></div><br />'); } } public function insertQ() { $query = ""; } } //======================================= //Usercp.php //======================================== if(isset($_GET['mode'])) { $mode = $_GET['mode']; } else { $mode = 'usercp'; } switch($mode) { case 'usercp': echo 'Welcome to the User Control Panel'; break; case 'logging': require_once 'class.logging.php'; $logger = new logging(); if(isset($_POST['submit']) { if($logger->validate_post === true) { $logger->insertQ(); require_once '/scripts/PHPMailer/class.phpmailer.php'; $mailer = new PHPMailer(); $mailer->PHPMailer(); } else { echo ''.$logger->showErrors.''; } } else { echo ' <form action="'.$_SERVER['PHP_SELF'].'?mode=logging" method="post"> </form> '; } break; case 'user_logout': // do somthing break; case 'user_settings': // do somthing break; ?>

  • First try StructureMap and MVC3 via NuGet

    - by Angel Escobedo
    Hello Guys, I'm trying to figure how to config StructureMap for ASP.NET MVC3 I've already using NuGet and I notice that it creates App_Start Folder with a cs file named as StructuremapMVC, so I check it and notice that is the same code but simplified that will be written manually on App_Start section placed on Global.asax... My Question is when I inject some IoC on my Controllers as the follow (I use this pattern : Entity Framework 4 CTP 4 / CTP 5 Generic Repository Pattern and Unit Testable) : private readonly IAsambleaRepository _aRep; private readonly IUnitOfWork _uOw; public AsambleaController(IAsambleaRepository aRep, IUnitOfWork uOw) { _aRep = aRep; this._uOw = uOw; } public ActionResult List(string period) { var rs = _aRep.ByPeriodo(period).ToList<Asamblea>(); return View(); } I got an Exception Exception Details: System.MissingMethodException: No parameterless constructor defined for this object.

  • Add column from another table matching results from first MySQL query

    - by Nemi
    This is my query for available rooms in choosen period: SELECT rooms.room_id FROM rooms WHERE rooms.room_id NOT IN ( SELECT reservations.room_id FROM reservations WHERE ( reservations.arrivaldate >= $arrival_datetime AND reservations.departuredate <= $departure_datetime) OR ( reservations.arrivaldate <= $arrival_datetime AND reservations.departuredate >= $arrival_datetime ) OR ( reservations.arrivaldate <= $departure_datetime AND reservations.departuredate >= $departure_datetime ) ); How to add average room price column for selected period(from $arrival_datetime to $departure_datetime) from another table (room_prices_table), for every room_id returned from above query. So I need to look in columns whos name is same as room_id... room_prices_table: date room0001 room0002 room0003 ... Something like SELECT AVG(room0003) FROM room_prices_table WHERE datum IS BETWEEN $arrival_datetime AND $departure_datetime ??

  • What comes first in Ruby's object model?

    - by Timothy
    I've been reading Metaprogramming Ruby and the object model like the chicken or egg dilemma. In Ruby 1.8, the Object class is an instance of Class. Module's superclass is Object and is an instance of Class. Class' superclass is Module, and it is an instance of Class (self-referential). Say class SomeClass; end is defined somewhere; SomeClass is an instance of Class, however its superclass is Object. Why does an instance of Class have Object as the superclass instead of nil? Also, if Object is to exist, then Class has to exist, but then Module has to exist, but for Module to exist Object has to exist. How are these classes created?

  • [C++] My First Go With Function Templates

    - by bobber205
    Thought it was pretty straight forward. But I get a "iterator not dereferencable" errro when running the below code. What's wrong? template<typename T> struct SumsTo : public std::binary_function<T, T, bool> { int myInt; SumsTo(int a) { myInt = a; } bool operator()(const T& l, const T& r) { cout << l << " + " << r; if ((l + r) == myInt) { cout << " does add to " << myInt; } else { cout << " DOES NOT add to " << myInt; } return true; } }; void main() { list<int> l1; l1.push_back(1); l1.push_back(2); l1.push_back(3); l1.push_back(4); list<int> l2; l2.push_back(9); l2.push_back(8); l2.push_back(7); l2.push_back(6); transform(l1.begin(), l1.end(), l2.begin(), l2.end(), SumsTo<int>(10) ); }

  • HTML Link and Jquery Live Only Works on First Try with one click

    - by Jon
    Hi Everyone, I'm running into a problem with jquery live event binding on a link. When the link is added to the page it works fine, however when another link is added to the unordered list it requires two clicks for the click event to fire on either link. Any ideas? $("div#website-messages ul li a").live("click", function() { var link = $(this); changeTab(link.attr("href")); $(link.attr("title")).focus(); return false; });

  • qTip pop ups come in from top left of screen (on first load)

    - by franko75
    Hi, not sure if i'm set things up incorrectly - I don't seem to see anyone else with this problem, but my qTip popups (all ajax loaded content) are loading quite erratically, in that they are often animating in from off screen before appearing in the correct position. Is there a simple solution to this which I may have missed? Thanks again for your help. HTML markup: <span class="formInfo"> <a href="http://localhost/httpdocs/index.php/help/kc_dob" class="jTip" name="" id="dob_help">?</a> </span> qTip initialisation.. //set up for qtip function initQtip() { $('a.jTip').each(function() { $(this).qtip( { content: { // Set the text to an image HTML string with the correct src URL to the loading image you want to use text: '<img src="/media/images/wait.gif" alt="Loading..." />', url: $(this).attr('href') // Use the rel attribute of each element for the url to load }, position: { adjust: { screen: true // Keep the tooltip on-screen at all times } }, show: { when: 'click', solo: true // Only show one tooltip at a time }, hide: 'unfocus', style: { tip: true, // Apply a speech bubble tip to the tooltip at the designated tooltip corner border: { width: 10, radius: 10 }, width: { min: 200, max: 500 }, name: 'light' // Use the default light style } }); //prevent default event on click }).bind('click', function(event){ event.preventDefault(); return false; }); }

  • Selecting only the first item of an xpath result set in PHP

    - by IkimashoZ
    I am currently achieving the desired outcome with two PHP statements: $thisBlarg = $xmlResource->xpath('//blarg[@ID='.$someBlargID.']'); echo $thisBlarg[0]->name; But, not wanting to settle for second best, I'd really prefer this to be one statement, but PHP doesn't like this: echo $xmlResource->xpath('//blarg[@ID='.$someBlargID.']')[0]->name; And for good reason. But I can't find a way to force an xpath query to return the result directly. Any suggestions?

  • how to go back to first if statement if no choices are valid - python

    - by wondergoat77
    how can i have python move to the top of an if statement if nothing is satisfied correctly i have a basic if/else statement like this: print "pick a number, 1 or 2" a = int(raw_input("> ") if a == 1: print "this" if a == 2: print "that" else: print "you have made an invalid choice, try again." what i want is to prompt the user to make another choice for 'a' this if statement without them having to restart the entire program, but am very new to python and am having trouble finding the answer online anywhere.

  • Learn Silverlight or WPF first?

    - by Phil Wright
    It seems that Silverlight/WPF are the long term future for user interface development with .NET. This is great because as I can see the advantage of reusing XAML skills on both the client and web development sides. But looking at WPF/XAML/Silverlight they seem very large technologies and so where is the best place to get start? I would like to hear from anyone who has good knowledge of both and can recommend which is a better starting point and why.

    I have to create an SQL Query to get all rows starting with a specific character, except if the parameter passed to the (PHP) function is 0, in that case it should get every row that does not start with A - Z (like #0-9.,$ etc).

  • Jquery find first visible element after horizontal scroll

    - by lolo flores
    I’m new (only two weeks old) in Jquery, so please bear with me. I know that a very similar question was asked some time ago but I do not know how to adapt the answer to my problem. I have a very wide multicolumn layout something like this: | aaaa | bbbb | cccc | … | | aaaa | b | cc | … | | aaa | cccc | ddd | … | The code looks like: <div id="container"> <p>aaaaaaaaaaa</p> <p>bbbbb</p> <p>ccccccccccc</p> <p>dddddddddd</p> ... <p>xxxxxx</p> </div> There is no vertical scrolling and the container width is set in such a way that only two columns are shown. The user scrolls left or right to see the relevant text. What I want is to get the position currently on display, store it (maybe in a cookie) and retrieve it the next time the user opens the page. I think that I need a way of finding out what paragraph is currently the left-top most, but other suggestions are very welcome. Any ideas? btw: this is an internal project, so Mozilla only :-) Thanks Lolo

  • Javascript: find first n prime numbers

    function primeNumbers() { array = []; for (var i = 2; array.length < 100; i++) { for (var count = 2; count < i; count++) { var divisorFound = false; if (i % count === 0) { divisorFound = true; break; } } if (divisorFound == false) {array.push[i];} } return array; } When I run this code, it seems to get stuck in an infinite loop and doesn't return anything... why?

  • Remove only first instance of a character from a list of characters

    - by Luke
    Hi All, Here's what I want to do. I have 2 strings and I want to determine if one string is a permutation of another. I was thinking to simply remove the characters from string A from string B to determine if any characters are left. If no, then it passes. However, I need to make sure that only 1 instance of each letter is removed (not all occurrences) unless there are multiple letters in the word. An example: String A: cant String B: connect Result: -o-nec- Experimenting with NSString and NSScanner has yielded no results so far.
