  • Echo html+php from database

    - by pg-robban
    I am working on a site which deals with a lot of texts in HTML, so recently I learned PHP and moved them into a MySQL database and echo the contents given a specific chapter and section. Now this works relatively fine, the HTML shows up properly. However, in some parts I have included PHP function calls, and these doesn't seem to be evaluated - rather, they get just inserted into the source code (and thus invisible for the page viewer), never doing anything. They did work when they were simple .html files. How can I solve this? For example, a text can look like this: <?php printChapterName(); ?> <p>Some text</p> ... <?php showImage($name, $alt-text); ?> ... This just shows the text on the page. Edit: The functions are echo:ing some HTML.

    - by Rad The Mad
    How can I use/setup Tier Pricing with Configurable Products? (Magento 1.4+) There was an extension to do this but I think it is only for Magento 1.3.

Edit: In my case, I would like to use the Tier Pricing FROM the Simple Product. and not use the Tier Pricing from the Config. Product

  • Java Interfaces Methodology: Should every class implement an interface?

    - by Amir Rachum
    I've been programming in Java for a few courses in the University and I have the following question: Is it methodologically accepted that every class should implement an interface? Is it considered bad practice not to do so? Can you describe a situation where it's not a good idea to use interfaces? Edit: Personally, I like the notion of using Interfaces for everything as a methodology and habit, even if it's not clearly beneficial. Eclipse automatically created a class file with all the methods, so it doesn't waste any time anyway.

  • Uniform distance between points

    - by Reonarudo
    Hello, How could I, having a path defined by several points that are not in a uniform distance from each other, redefine along the same path the same number of points but with a uniform distance. I'm trying to do this in Objective-C with NSArrays of CGPoints but so far I haven't had any luck with this. Thank you for any help. EDIT I was wondering if it would help to reduce the number of points, like when detecting if 3 points are collinear we could remove the middle one, but I'm not sure that would help.

  • Efficiently Reshaping/Reordering Numpy Array to Properly Ordered Tiles (Image)

    - by Phelix
    I would like to be able to somehow reorder a numpy array for efficient processing of tiles. what I got: >>> A = np.array([[1,2],[3,4]]).repeat(2,0).repeat(2,1) >>> A # image like array array([[[1, 1, 2, 2], [1, 1, 2, 2]], [[3, 3, 4, 4], [3, 3, 4, 4]]]) >>> A.reshape(2,2,4) array([[[1, 1, 2, 2], [1, 1, 2, 2]], [[3, 3, 4, 4], [3, 3, 4, 4]]]) what I want: X >>> X array([[[1, 1, 1, 1], [2, 2, 2, 2]], [[3, 3, 3, 3], [4, 4, 4, 4]]]) to be able to do something like: >>> X[X.sum(2)>12] -= 1 >>> X array([[[1, 1, 1, 1], [2, 2, 2, 2]], [[3, 3, 3, 3], [3, 3, 3, 3]]]) Is this possible without a slow python loop? Bonus: Conversion back from X to A Edit: How can I get X from A?

  • Use currently logged-in user in query

    - by Degan
    I am using VisualWebDeveloperExpress2008 with Access as the membership provider. I have some cases where I want users to edit their own data. This would involve a query where the UserId should equal the UserID of the user who is using the site. I am expecting to use WHERE UserId = ?, but I have not found out where to direct "?". The IDE gives several choices, but I am uncertain which to choose. This, while it looks promising does not work: <SelectParameters> <asp:ProfileParameter Name="UserID" PropertyName="UserId" Type="Int32" /> </SelectParameters> What is best to use for the Select Parameter?

  • [C] How I change a variable of a type to another one?

    - by drigoSkalWalker
    I want to do it: int main () { bla bla bla void *onetype; switch (USER_INPUT_TYPE) { CASE CONVERT_TO_CHAR: convert onetype VOID TO CHAR HOW??? CASE CONVERT_TO_INT: convert onetype VOID TO INT HOW??? LOT OF CASES... } } Yes, I know type casting, but type casting is a 'temporary' change... So...Is there any way to accomplish it in C? EDIT : Stop stop stop! Please, see, what are you doing is type casting, I KNOW THIS, you are creating another variable of the desirable type like int i = (int) onetype, I don't want this, I want something else like onetype = (int) onetype, without recreate them, without allocate another variable. Thanks a lot guys!

  • how do i grab text of multiple tags in an xml feed using one xpath expression?

    - by Incognito
    Im trying to parse an xml feed that looks something like this: <item> <title>item title</title> <link>item link</link> <description>item description</description> </item> I'm trying to find an xpath expression that will retrieve all the details of each item so that each item in the feed is contained within its own array or grouped in some way. I tried using //item/* but the tags are not grouped, although they are correctly ordered. Is there anyway of doing that? edit: [ [title1, link1, desc1], [title2, link2, desc2], [title3, link3, desc3] ]

  • UIRotationGestureRecognizer changes with CGAffineTransformMakeScale

    - by user523234
    A view is flipped using this: self.transform = CGAffineTransformMakeScale(-1, 1); // self is an UIView To rotate this view: -(void)handleRotate:(UIRotationGestureRecognizer *)recognizer { recognizer.view.transform = CGAffineTransformRotate(recognizer.view.transform, recognizer.rotation); recognizer.rotation = 0; } The issue is that after the view is flipped so is the rotation's direction. Any solution how to fix this? Edit: My current solution is using a boolean and negate the recognizer.rotation value in handleRotate method. But I am still looking for the technical solution.

  • Rails: Generic form actions, cancel link losing `:back` on validation failure

    - by Patrick Connor
    I am trying to create a generic set of Submit, Cancel, and Destroy actions for forms. At this point, it appears that everything is working, except that I lose :back functionality then a form reloads due to validation errors. Is there a way to catch the fact that validation has failed, and in that case, keep the request.env['HTTP_REFERER'] or :back value the same without having to edit every controller? = simple_form_for @announcement do |f| = f.error_notification = f.input :message = f.input :starts_at = f.input :ends_at #submit = f.button :submit = "or " = link_to("cancel", url_for(:back)) .right - if !f.object.new_record? - resource = (f.object.class.name).downcase = link_to "destroy", url_for(:action => 'destroy'), :confirm => "Are you sure that you want to delete this #{resource}?", :method => :delete .clear .non_input #post_back_msg #indicator.inline = image_tag "indicator.gif" .inline = "Please wait..." .non_input

  • OS X Terminal: Meta key + alt functionality at the same time

    - by abababa22
    Is there a way to use "alt/option" key as a meta key but still be able to use the key to make some characters which need it? For example in my local keyboard layout: @ is alt-2 \ is alt-shift-7 | is alt-7 etc. So if I set alt as meta key, I can't make those characters. On the other hand using "press esc, release esc, press a key" to make meta key sequences makes my hands hurt. Any emacs users with international keyboards who have solved this, please give any tips you might have! :) edit: It appears that I can set alt as meta key and then add these kind of settings in inputrc: "\e2": "@" This works in bash shell but it still won't work with emacs though, so no good.

  • Communicating between an overlayed iFrame and the underlying page (LAMP)

    - by stef
    I have a small form is to be filled in. If the user is logged in, the form is submitted as normal. If the user is not logged in, I show an overlayer with an iframe'd page that contains a login box where he enters his credentials. If the credentials are correct I can "break out" of the frame to "return" to the main page, but how can I update this main page for example to show "you are now logged in" and to change the JS / PHP login that determines whether or not the form can be submitted normally and not be intercepted again by the overlayer prompt? Afaik, these two separate pages are not aware of each other so I'm struggling to find a solution to this problem. This is in a LAMP / jQuery / CodeIgniter environment. EDIT: Could CodeIgniter's XML RPC class be useful for this?

  • Get standard application for txt files (.NET)

    Possible Duplicate: Finding the default application for opening a particular file type on Windows Hello, in my application I want to open a text file, which has no .txt extension. Is there any way to get the standard application for .txt files in .NET (C#)? Sure I could use "notepad", but there might be some people (like me), who prefer another (their standard) editor. Thank you very much. Edit: The registry key "[HKEY_CLASSES_ROOT]\txtfile\shell\open\command" references notepad, but that's not my standard app for txt files. How do I get the my current standard app for .txt?

  • Selecting data effectively sql

    - by learner135
    Hi, I have a very large table with over 1000 records and 200 columns. When I try to retreive records matching some criteria in the WHERE clause using SELECT statement it takes a lot of time. But most of the time I just want to select a single record that matches the criteria in the WHERE clause rather than all the records. I guess there should be a way to select just a single record and exit which would minimize the retrieval time. I tried ROWNUM=1 in the WHERE clause but it didn't really work cause I guess the engine still checks all the records even after finding the first record matching the WHERE criteria. Is there a way to optimize in case if I want to select just a few records? Thanks in advance. Edit: I am using oracle 10g.

  • naming a method - using set() when *not* setting a property?

    - by user151841
    Is setX() method name appropriate for only for setting class property X? For instance, I have a class where the output is a string of an html table. Before you can you can call getTable, you have to call setTable(), which just looks at a other properties and decides how to construct the table. It doesn't actually directly set any class property -- only causes the property to be set. When it's called, the class will construct strHtmlTable, but you can't specify it. So, calling it setTable breaks the convention of get and set being interfaces for class properties. Is there another naming convention for this kind of method? Edit: in this particular class, there are at least two ( and in total 8 optional ) other methods that must be called before the class knows everything it needs to to construct the table. I chose to have the data set as separate methods rather than clutter up the __construct() with 8 optional parameters which I'll never remember the order of.

  • Is it possible to easily modify the log4net section in the config file of several running applicatio

    - by mark
    Dear ladies and sirs. Our product consists of client, server and agents. Each deployed on different machines. The QA is having a hard time to manipulate the log4net sections in the respective config files. Right now, they have to have remote desktops to all the relevant machines and open notepad in each of them and then edit the files one at a time switching between different machines as they proceed. A real pain in the ass. Can anyone suggest a better solution to this problem? Thanks.

  • Unique number identifier generation

    - by xwrs
    I have to create logic for generation unique number identifier for records in database. id, generated in database is a separate column. At this moment, when user calls "create record" action, I save new record, get its database id, generate record number using this id, then put it to the edit form. Using this way means that all entity fields should be nullable to save record to database. I don't like this way. I know that should be better way. Is there a better practice to generate unique number identifier? What is possibility of generating non-unique random numbers? Thank you

  • Obtaining kerning information

    - by chadb
    How can I obtain kerning information for GDI to then use in GetKerningPairs? The documentation states that The number of pairs in the lpkrnpair array. If the font has more than nNumPairs kerning pairs, the function returns an error. However, I do not know how many pairs to pass in, and I don't see a way to query for it. EDIT I tried to do the following, however, it still gave me 0. Font* myFont = new Font(L"Times New Roman", 10); Bitmap* bitmap = new Bitmap(256, 256, PixelFormat32bppARGB); Graphics* g = new Graphics(bitmap); SelectObject(g->GetHDC(), myFont); //DWORD numberOfKerningPairs = GetKerningPairs( g->GetHDC(), -1, NULL ); DWORD numberOfKerningPairs = GetKerningPairs( g->GetHDC(), INT_MAX, NULL );

  • Apache file caching

    - by danp
    How does apache handle caching of certain files, and is it possible to explicitly say that certain files should be aggressively cached more than others, through the standard config files for a given host or virtualhost? To put it in context, I keep a lot of site content in various XML files, and I'd like to be able to say that this file will be used a lot, and therefore cache it as much as possible..? Does apache do this kind of thing intelligently and on the fly..? Will it observe which files are more popular than others and try to match cache hits appropriately..? Lots of questions in one, but the basic idea should be clear enough. edit: to be clear, these are resource files which are loaded and interpreted by PHP - but php as a process is spawned inside apache.. right? Please help!

  • ios - almost there with updating Core Data

    - by Jeff Kranenburg
    I have been following the answer of this question: How to update existing object in core data? and in the answer it comes across this line of code to update a record within the array: Favorits* favoritsGrabbed = [results objectAtIndex:0]; Now this updates whatever is set a record 0 of the database, no matter what cell I select to edit. I am sorry but I cannot figure out how to change it into updating the cell I have selected. Starting to grow grey hairs here:-) The problem (maybe it is my mindset) is that I am required to give an integer and I am unable to find something to substitute it. Any help would be great.

  • TabBars and iOS 7

    - by MichaelScaria
    I have a UITabbarController that I'm pushing another controller on top of using a UINavigationController. On iOS 6 and below, the tabBar of the parent controller slides away and the toolbar of the new view controller is presented. But on iOS 7 the tabBar doesn't animate away even if I run the code [self.navigationController setToolbarHidden:YES animated:NO]; EDIT - Okay I narrowed my problem to iOS 7 not respecting the hidesBottomBarWhenPushed property, I followed the answers in hidesBottomBarWhenPushed ignored in iOS 7 but it didn't work. The view that is pushed has a toolbar with buttons and the buttons are responding to touches, it's just that the tabBar is on top of the toolbar.

  • Dynamically generate Triangle Lists for a Complex 3D Mesh

    - by Vulcan Eager
    In my application, I have the shape and dimensions of a complex 3D solid (say a Cylinder Block) taken from user input. I need to construct vertex and index buffers for it. Since the dimensions are taken from user input, I cannot user Blender or 3D Max to manually create my model. What is the textbook method to dynamically generate such a mesh? Edit: I am looking for something that will generate the triangles given the vertices, edges and holes. Something like TetGen. As for TetGen itself, I have no way of excluding the triangles which fall on the interior of the solid/mesh.
