  • How can I handle validation of non-latin script input in PHP?

    - by Matt
    I am trying to adapt a php application to handle non-latin scripts (specifically: Japanese, simplified Chinese and Arabic). The app's data validation routines make frequent use of regular expressions to check input, but I am not sure how to adapt the \w character type to other languages without installing additional locales on the system (which I cannot rely on). Previous developers to have worked on the app have simply added needed characters to the regexes as the number of languages we supported grew (you frequently see "[\wÀÁÂÃÄÅÆÇÈÉ... etc" in the code), but I can't really do this for all the alphabets I need to support now. Does anybody out there have some advice on how to tackle this?

  • Signs that a SQL statement is dangerous

    - by Matt
    Hi, I want to develop a function in PHP that checks how dangerous a SQL statement is. When i say dangerous i mean, certain symbols, characters or strings that are used to get data from a database that the user shouldnt see. For example: SELECT * FROM users WHERE userId = '1' can be injected in several ways. Although i clean the params, i also want to monitor how safe the query is to run. Thanks in advance

  • Postion of & to denote reference type

    - by Matt H
    I was wondering whether to put the ampersand (&) after the variable type or before the variable name. To put it simply, I want to know which one is the conventional style or the standard, or if it is entirely down to preference. int &x; or int& x;

  • Reading from CSVs in Python repeatedly?

    - by matt
    I'm trying to check the value of extracted data against a csv I already have. It will only loop through the rows of the CSV once, I can only check one value of feed.items(). Is there a value I need to reset somewhere? Is there a better/more efficient way to do this? Thanks. orig = csv.reader(open("googlel.csv", "rb"), delimiter = ';') goodrows = [] for feed in gotfeeds: for link,comments in feed.items(): for row in orig: print link if link in row[1]: row.append(comments) goodrows.append(row)

  • iphone app working on most devices but not a few

    - by Matt Facer
    Hi there. I have recently been rewriting some of my iphone app because a couple of users have said it was crashing on certain events. The event in question is when I add a new XIB to the view using the following code AddItemViewController * add_item = [[AddItemViewController alloc] initWithNibName:@"AddItem" bundle:[NSBundle mainBundle]]; [self presentModalViewController:add_item animated:YES]; [add_item setViewFormat:2]; [add_item release]; it works perfectly on my iphone and a mate's ipod touch (both running 3.1.3) but another user on an ipod touch also with 3.1.3 says it crashes when the function above is called. Why could this be happening? Surely if it works on one device it should work on another?! Is there a better way to add a view which maybe doesnt crash? I have also disabled all the code on the loading xib - so it literally is loading a near blank page. It's SO annoying!! Thanks for any help.

  • style a navigation link when a particular div is shown

    - by Matt Meadows
    I have JQuery working to show a particular div when a certain link is clicked. I have managed to apply the effect I'm after with the main navigation bar through id'ing the body tag and using css to style when the id is found. However, i'd like to apply the same effect to the sub navigation when a certain div is present. How the main navigation is styled: HTML: <nav> <ul> <li id="nav-home"><a href="index.html">Home</a></li> <li id="nav-showreel"><a href="showreel.html">Showreel</a></li> <li id="nav-portfolio"><a href="portfolio.html">Portfolio</a></li> <li>Contact</li> </ul> </nav> CSS: body#home li#nav-home, body#portfolio li#nav-portfolio { background: url("Images/Nav_Underline.png") no-repeat; background-position: center bottom; color: white; } (Other links havent been added to styling as those pages are still in development) How the sub navigation is structured: <nav id="portfolioNav"> <ul> <li id="portfolio-compositing"><a id="compositingWork" href="#">Compositing</a></li> <li id="portfolio-animation"><a id="animationWork" href="#">Animation</a></li> <li id="portfolio-motionGfx"><a id="GFXWork" href="#">Motion Graphics</a></li> <li id="portfolio-3D"><a id="3DWork" href="#">3D</a></li> </ul> </nav> As you can see, its similar format to the main navigation, however i've tried the same approach and it doesn't work :( The Javascript that switches the divs on the navigation click: <script type="text/javascript"> $(document).ready(function() { $('#3DWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #Portfolio3D'); }); $('#GFXWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #motionGraphics'); }); $('#compositingWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #PortfolioCompositing'); }); $('#animationWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #PortfolioAnimation'); }); }); </script> JSFiddle for full HTML & CSS : JSFiddle File The effect I'm After:

  • How to switch data pins on/off on parallel port?

    - by Matt
    I want to simply switch certain data pins on and off, so that they can control a set of relays. I'm not asking about the hardware bit (should be easy), but I don't know where to begin writing the software. I don't want a high level library that can send bytes to a device - I literally want to switch on/off certain pins. I'm running Linux and I want to do this in Java, so would I just need a library? It would be nice if the library has good documentation and is easy to use, but if not then a short example code will help me get started.

  • PHP - How do i display the first 20 li then have a link to display more (gallery)

    - by Matt Rogers
    I want to display about 20 li on a page with a link at the bottom that says something like 'display more'. This link will then clear the first 20 and display the next 20. How should i go about doing this. (I am creating a gallery) I was thinking about using PHP and MySQL. However for what I am doing I do not really need to store it in a database so is there an easier way of doing it only using html, php or javascript? thanks

  • Credit card validation with regexp using test()

    - by Matt
    I'm trying to complete some homework and it appears the book might have gotten it wrong. I have a simple html page that allows user to pick a credit card in our case american express. The user then enters a number and evalutes that number based on a regular expression. My question ends up being when test() evaluates the number it returns a boolean or a string? I should then compare that string or boolean? True == true should fire off the code in a nested if statement. Heres what the book gives me as valid code: if(document.forms[0].cardName.value == "American Express") { var cardProtocol = new RegExp("^3[47][0-9]{13}$"); //REGEX ENTRY HERE if(cardProtocol.test(document.forms[0].cardNumber.value)) document.forms[0].ccResult.value = "Valid credit card number"; } The above code doesn't work in firefox. I've tried modifying it with 2 alerts to make sure the number is good and the boolean is good...and still no luck: if(document.forms[0].cardName.value == "American Express") { var cardProtocol = new RegExp("^3[47][0-9]{13}$"); //REGEX ENTRY HERE <------ alert(document.forms[0].cardNumber.value) alert(cardProtocol.test(document.forms[0].cardNumber.value)) if((cardProtocol.test(document.forms[0].cardNumber.value)) == true ) // <--Problem { document.forms[0].ccResult.value = "Valid credit card number"; } else { document.forms[0].ccResult.value = "Invalid credit card number"; } } Any ideas? the if loop is the culprit but I'm not figuring out why it is not working. Please throw up the code for the if loop! Thanks for the help!

  • How to distinguish between new and returning anonymous Drupal users?

    - by Matt V.
    Is there an easy way (or a module) in Drupal to distinguish between anonymous users who have never created an account versus those who are returning but are not currently logged in? For non-returning (ie, completely new) users, I'd like to have a front page that is very streamlined and focused on registration as the call-to-action. However, if someone is a returning user but not currently logged in, I'd like to present a lot more information on the front page and have login as the main call-to-action. I realize both pages would still need to have both login and register options available, I just want to make the focus significantly different between the two.

  • How to get the value of an attribute from XML file in PHP?

    - by Matt
    Hi, Sorry if this seems like an easy question, but I've started pulling hair out on this... I have a XML file which looks like this... <VAR VarNum="90"> <option>1</option> </VAR> I'm trying to get the VarNum. So far I've been successful using the follow code to get the other information: $xml=simplexml_load_file($file); $option=$xml->option; I just can't get VarNum (the attribute value I think?) Thanks!

  • CSS: How to set remaining width as %, but having knowledge of only pixels

    - by Mega Matt
    Hi all, I've seen this question asked in a couple other contexts on SO, but I thought it would be worth asking again for my particular case. I'm trying to create some re-usable CSS classes for more consistency and less clutter on my site, and I'm stuck on trying to standardize one thing I use frequently. I have a container div that I don't want to set the height for (because it will vary depending on where on the site it is), and inside it is a header div, and then an unordered list of items, all with CSS applied to them. It looks a lot like this: I want the unordered list to take up the remaining room in the container div, knowing that the header div is 18px tall. I just don't know how to specify the list's height as "the result of 100% minus 18px". Does anyone have any advice in this situation? Thanks very much.

  • Javascript Date: Ensure getMinutes(), getHours(), getSeconds() puts 0 in front if necessary

    - by Mega Matt
    Hi all, Looking for a creative way to be sure values that come from the getHours, getMinutes, and getSeconds() method for the javascript Date object return "06" instead of 6 (for example). Are there any parameters that I don't know about? Obviously I could write a function that does it by checking the length and prepending a "0" if need be, but I thought there might be something more streamlined than that. Thanks.

  • forwarding packets from wireless nic wlan0 to another Wireless nic wlan1

    - by user179759
    I have two wireless interfaces wlan0, wlan1 I want wlan0 to be connected to the internet via a wireless router and I want wlan1 to be in AP mode acting as a router to give internet access to whoever connectes to it. So basically all packets coming through wlan1 should be forwarded to wlan0 = Router = Internet. That's including DNS/DHCP/etc.. [A]~~~~~(Wi-Fi)~~~~~~v [B]~~~~~(Wi-Fi)~~~> [me] ~~~~(Wi-Fi)~~~~~>[AP/Router]------->[internet] [C]~~~~~(Wi-Fi)~~~~~~^ Any idea how can I do this? ps: I tried using bridges but I always get 'operation not supported' using the brctl tool.

  • IT Asset Management

    - by CogitoErgoSum
    Our company has grown quite quickly and I am facing new tasks which I did not think I'd need to deal with. Recently we've come ot a point where we have 100+ Devices (Routers, Bridges, Computers, Laptops, VOIP Phones etc). The other day I was quite frightened when I asked for an inventory and no one had one. I want to start tagging all equipment and recording serials to begin tracking our inventory and ensuring we have a proper record of what equipment we have. Does anyone have advice as to how to go about 1. Convincing the higher ups why we need to do this and 2. What software or strategies might work? Keep in mind this is not for furniture, office equipment etc but IT specific equipment. I'm concerned over people 1. Stealing the physical devices and 2. Losing track of configuration data etc in case we'd need to do a wipe and restore

  • What hardware is at physical address 0x80000000 on powerpc New World Macintosh?

    - by tinkerer
    Open Firmware device tree gives no clue what device might decode at physical address 0x80000000 to 0x8008200 on a G4 New World Macintosh. The mmu has three adjacent Virtual=Real translations for that block. They are the only address translations reported between the top or physical dram at 20000000 and the start of the PCI bridges at f0000000. (A possible clue is that frame-buffer-addr is reported as 9c008000 by Open Firmware, and that is not in the reported translation table either). I believe the architecture has been around since about 1999.

  • Bridging two sockets

    - by Itehnological
    I wondered if it is possible to bridge two incoming tcp sockets. For example: Client A -----> Server <----- Client B The the server sends it's magic to both clients and then they connect to each other bypassing the server Server Client A ----------><---------- Client B UPDATE: The idea is when those clients can't bind to ports to listen to still be able to create connection between each other with the help of the server. For example Client A and Client B have tcp sockets with the server. User A decides to chat with User B and creates a new tcp connection with the server with the request to bridge it with User B. The server sends that request to Client B and it also opens up a new tcp connection with the server for that chat line. Now when the server has both chat connections from A and B it bridges them and they can work without the server, and as a result the server won't have to process all the messages and files the two users share. That's the idea/

  • Cisco 350 Bridge vxWorks connecting to IOS

    - by jinanwow
    I have 2 bridges one is a Cisco 350 Bridge with vxWorks as a non-root bridge w/o clients and another Cisco 350 Bridge running IOS set as Root Bridge. It seems no matter what configuration I can't seem to associate the vxworks to the IOS bridge. I have even tried swapping the roles and they still do not communicate. Any ideas how I can make the two connect, I would have upgraded the 350 to IOS as well but it will not upgrade. From my research it appears there is no way for these two devices to communicate but I wanted to be sure of that.

  • What protocols will/are ISPs use for IPv6 deployment?

    - by rbeede
    Currently ISPs deal out addresses via DHCP for IPv4 dynamic (single) addresses. What protocol will/are ISPs going to use for IPv6 when they can hand a customer an entire /64 (or /48 if they are nice) block? DHCPv6, RA? For ISPs that support true end-to-end IPv6 will they provide gateway devices (similar to cable modem or true DSL bridges for example) that receive border information for that specific customer? I'm just trying to get an idea of how your common residential service customer will have to configure things in an IPv6 Internet (whenever that comes). Will it be something customers are expected to statically configure on their home wireless router? Today with IPv4 I do it like this: Modem (bridge) passes public IPv4 obtained via DHCPv4 from ISP to second device (wireless router). It in turn has its own DHCPv4 service it provides on the internal lan.
