• If you could remove one feature of php to help newbies what would it be?

  - by Chris

  If you could remove one feature from PHP so as to discourage, prevent or otherwise help stop newer programmers develop bad habits or practices, or, to stop them falling into traps that might hinder their development skills what would it be and why? Now, before the votes to close it's not as open-ended as you might think. I'm not asking purely what is the worst feature or what feature would you really like to remove purely arbitrarily. Yes, there may not be one correct answer but I suspect there will be many similar answers which will provide me with a good idea of things I might be doing wrong, even inadvertently.

• mod_rewrite: no ? and # in REQUEST_URI

  - by tshabala

  Hello. What I'm trying to do: have pretty URLs in the format 'http://domain.tld/one/two/three', that get handled by a PHP script (index.php) by looking at the REQUEST_URI server variable. In my example, the REQUEST_URI would be '/one/two/three'. (Btw., is this a good idea in general?) I'm using Apache's mod_rewrite to achieve that. Here's the RewriteRule I use in my .htaccess: RewriteRule ^/?([a-zA-Z/]+)/?$ /index.php [NC,L] This works really well thus far; it forwards every REQUEST_URI that consists of a-z, A-Z or a '/' to /index.php, where it is processed. Only drawback: '?' (question marks) and '#' (hash keys) seem to still be allowed in the REQUEST_URI, maybe even more characters that I've yet to find. Is it possible to restrict those via my .htaccess and an adequate addition to the RewriteRule? Thanks!

• dabbledb + iPhone

  - by user193545

  I have been using DabbbleDB online database for storing/retrieving values for one of my iPhone applications. I am using their JSON response for retrieving the records. The problem that I am facing is that if there are a large number of records in the database, it takes a long time to get the response from the server and then to parse the JSON response. Instead I would like to to get a set of records at a time and run a loop to fetch all the records in background. I do not know whether we can query for a set of records at a time from online databases like DabbleDB. Anybody having an idea, please help.

• How to change the elements in the page base on user who is logged in

  - by user225269

  Please give me an idea on how to display elements in a page depending on who is logged in. For example, a user or an administrator. I'm thinking of something like this but I get a parse error, what do I lack in this code?: <?php session_start(); if (!(isset($_SESSION['loginAdmin']) && $_SESSION['loginAdmin'] != '')) { header ("Location: loginam.php"); } if else (!(isset($_SESSION[['loginAdmin']) && $_SESSION['loginAdmin'] =='')) { ?> <?php include('head2.php'); ?> } <?php if (!(isset($_SESSION['login']) && $_SESSION['login'] != '')) { header ("Location: login.php"); } if else (!(isset($_SESSION[['login']) && $_SESSION['login'] =='')) { ?> <?php include('head3.php'); } ?> Please help

• C# Generics Multiple Inheritance Problem

  - by Ciemnl

  Can any one help me with this syntax issue with C#? I have no idea how to do it. class SomeClass<T> : SomeOtherClass<T> where T : ISomeInterface , IAnotherInterface { ... } I want SomeClass to inherit from SomeOtherClass and IAnotherInterface and for T to inherit ISomeInterface only It seems the problem is that the where keyword screws everything up so that the compiler thinks both ISomeInterface and IAnotherInterface should both be inherited by T. This problem is very annoying and I think the solution is some kind of parenthesis but I have tried and failed finding one that works. Also, switching around the order of the two items inherited from SomeClass does not work because the class inherited always has to come before any interfaces. I couldn't find any solutions on the MSDN C# generics pages and I can't beleive I'm the first person to have this problem. Thanks, any help is much appreciated!

• reading files provided via $_GET

  - by Max

  I have a php script which takes a relative pathname via $_GET, reads that file and creates a thumbnail of it. I dont want the user to be able to read any file from the server. Only files from a certain directory should be allowed, otherwiese the script should exit(). Here is my folder structure: files/ <-- all files from this folder are public my_stuff/ <-- this is the folder of my script that reads the files My script is accessed via mydomain.com/my_stuff/script.php?pathname=files/some.jpg. What should not be allowed e. g.: mydomain.com/my_stuff/script.php?pathname=files/../db_login.php So, here is the relevant part of the script in my_stuff folder: ... $pathname = $_GET['pathname']; $pathname = realpath('../' . $_GET['pathname']); if(strpos($pathname, '/files/') === false) exit('Error'); ... I am not really sure about that approach, doesnt seem too safe for me. Anyone with a better idea?

• Drupal vs Some Other CMS

  - by Vecta

  I'm going to be moving my website to a CMS in the coming months I'd I need some help on choosing an appropriate CMS. Many of the websites I've seen tend to say "use Drupal, hands down". However, my website truly doesn't have a need for commenting or community features. Its pages will need to be modified occasionally, but not extensively. My website will also consist of many programs, each with their own sub-pages and menus. There are probably 25 people that will need access to the content on my website and will need the ability to update it. I do like the idea of being able to tag and categorize the content, and the modular aspect of Drupal but is it really right for my website? If not, which CMS may fit my needs better?

• Simple parameter checking function, here just want the % to be allowed

  - by abas_rafiq

  I'm using PDO's bindParam. This is the function which checks every GET variable on the website. After changing it will echo it out: function Check_Get_Param($val){ $value1=addslashes($val); $string1=htmlspecialchars($value1); $string2=strip_tags($string1); $string3=intval($string2); return $string3; } Hhere this will output the result: Check_Get_Param($_GET['id']); Now the idea is any id or id= any or id = % $_GET['id'] = % will result 0 as % is not integer. How to allow % also? How do I modify this function or any other function that I could filter the GET parameters so I could keep out the web from injections?

• Adding a border (Fixed3D) to an existing borderless application

  - by Aphelion

  Hi there, I have an .NET application that always starts itself with its border style to 'None', as it is supposed to be an full-screen application with a fixed resolution. However, i would like to add the window border (Fixed3D) to this window when the application starts so that I am able to move it around my desktop. My first idea was to have a tray app running, monitoring event messages, and somehow change the window style when this specific application starts. However, I am not sure if this will work and how to do this. Anyone that can point me in the right direction?

• Did anybody use the constream (constrea.h) lib?

  - by user337938

  Two years ago, I used the conio.h (actually conio2.h for Dev-C++) to create a console form interface. Now I want to make the same thing, but C++ std lib does not provide the needed functions and I don't want to use the old C conio lib. I found some websites which highlights the constream lib, but I have no idea to use it on VS! I tried just copying the header file into my project, but VS show several erros. I believe I am doing something wrong. ps: i got this file: ftp://ftp.cs.technion.ac.il/pub/misc/baram/TC31/INCLUDE/CONSTREA.H

• headfile conflict let every line becomes "not declared"

  - by altria

  I have a.h a.cpp b.h and a library for b. The thing is, if I choose to include b.h in either a.h or a.cpp, it will let complier return "was not declared in this scope" for every line of a.h. The same program works fine on another computer, although Makefile might be different. I have to admit, I think I may have change some settings, but I forgot which one I changed. Is there anybody have any idea? I am using linux and gcc.

• WhatsApp - writing a clone (iphone, android, wp7)

  - by Martin

  I am trying to create a instant messaging app very much like whatsapp I suppose. My resources I have available to me are Server development in C# (REST Service, dedicated server app etc) And currently an android development platform using eclipse (iphone, wp7 to follow later). I have done some development in Android before but I don't have any idea where to start an application like this. My guess would be it would work with UDP / TCP or similar ? I currently have a shared server for an asp.net website but I presume this wouldn't be ideal, I could essential setup a web service on the server and get a client to publish his messages there but then this would mean that the receivers would have to POLL (PULL) every 5 minutes or so - so I guess this wouldn't be real time Do I need to use UDP here ? And I presume platforms like Iphone, Android and WP7 will not have any issues sending msgs by UDP - if that is how its done. I look forward to any help or guidance.

• Non-empty list with null elements returned from Hibernate query

  - by John

  Hi, I'm new to hibernate so not sure if this is an expected behaviour, anyway: Session session = (Session)entityManager.getDelegate(); Criteria criteria = session.createCriteria(myRequest.class); criteria.add(Restrictions.eq("username", username)); criteria.setProjection(Projections.max("accesscount")); List<myRequest> results = criteria.list(); The returned results is a non-empty list with a single null element. I can't think of any reason why it should behave this way, any idea if this is the expected behaviour or have I done something wrong? System is on hibernate/Syabse. Thanks.

• do you need captcha validation in newsletter subscription?

  - by user354051

  I am using a custom captcha php script along with news letter scripts to let users subscribe using an email id. The method of registration is based on jQuery.post command. My question is that am I really safe If I remove the captcha validation from my subscription script. The subscription is simple. For example mydomain/[email protected] The subscribe.php is called along with email as parameter using jQuery.post command. I am new to web programming stuff and don't have much idea about spammers in conjunction with above scenario. Any advise would greatly be appreciated. Thanks

• C++ setting up "flags"

  - by sub

  Example: enum Flags { A, B, C, D }; class MyClass { std::string data; int foo; // Flags theFlags; (???) } How can I achieve that it is possible to set any number of the "flags" A,B,C and D in the enum above in an instance of MyClass? My goal would be something like this: if ( MyClassInst.IsFlagSet( A ) ) // ... MyClassInst.SetFlag( A ); //... Do I have to use some array or vector? If yes, how? Are enums a good idea in this case?

• Merge Twitter Outh and Facebook Connect Friends

  - by G Ullman

  Basically what I want to do is download all a users facebook and twitter friends and somehow find a way to figure out which entries represent the same person. I know it's possible because a lot of social search sites like spokeo achieve what I want and more, so does anyone know how they go about doing it or the best way to go about it? I have a basic idea of the facebook and twitter api calls I need to be making however feel free to add any advice or warnings there as well. I know facebook hashes the emails which seems like it could pose a problem. Any help is greatly appreciated.

• PHP Losing variable data

  - by Conor B

  Hi, I'm having an issue with PHP losing data in a variable. There is quite a bit of data in the variable, because it basically contains a binary file, but I'm wondering if this is cause for it to completely lose it's information. Looking at a snippet from my code which is used to deal with email attachments: var_dump($data) if (array_key_exists('filename', $params) || array_key_exists('name', $params)) { var_dump($data) ... } The first var_dump gives the desired output of the file: "string(283155) " --Apple-Mail-5-930065543 ... etc while the second gives an output of: string(0) "" ... string(0) "" Any idea why this is happening? Does PHP just drop data in variables if they are really large? (I didn't think so, as I've never had this problem before) If so, any workaround? Thanks!

• Implementing an Online Waiting Room

  - by saalon

  My organization is building a new version of our ticketing site and is looking for the best way to build an online waiting room when the number of users in our purchase path exceeds a certain limit. The best version of this queue would let new users in after existing users have either completed their purchase or have exceeded a timeout limit after entering the path. I'm trying to get an idea of how this has been implemented by other organizations. Has anyone out there done something similar or have any experience with this? We have some ideas, but I'd like to get a sense of what solutions have been tried and what problems those solutions have run up against. Just to be complete, this site is being built in Ruby on Rails, though I'd love to hear about how people have solved this regardless of platform.

• Navigating sharepoint with a treeview

  - by linqmonkey

  I'm trying to replace the navigation on our sharepoint site with a treeview. It's a large site with up to 4 subsite leves in places. All I need it to do is show a consistent structure from page to page show only sites and pages The default sharepoint treeview seems to do neither of these things (doesn't display items from the parent site, includes document libraries but not pages). Does anyone have any idea how to achieve this? We're using the publishing site template throughout if that makes a difference. I've tried binding the tree to the datasource the quick launch uses but I guess from the error message they expect differently named properties.

• Dynamic web widget

  - by user1824996

  My vendor offers a widget creation service where I can login to their page, set initial values of a search form, after the save button is clicked, I can copy & paste the script code on my website to display a product search result widget. I am thinking to change this static widget to a dynamic one. Since my programming knowledge is limited, can experts tell me if it's possible to login https remotely (using cURL) and set search form values equal to values on my page (every time my page content changes, it will change the form value), then save the form. So the widget script I pasted on my page will always be refreshed to new search result. So the issue will involve cross domain, form submission & server/browser communication. I know a little jQuery, PHP, Ajax, cURL but so far I stuck with just having an idea but not really sure how to implement it.
