  • .htacces to create friendly URLs. Help needed....

    - by Jonathan
    Hi, I'm having a hard time with .htacces. I want to create friendly URLs for a site I'm working on... Basically I want to convert this: http://website.com/index.php?ctrl=pelicula&id=0221889 http://website.com/index.php?ctrl=pelicula&id=0160399&tab=posters Into this: http://website.com/pelicula/0221889/ http://website.com/pelicula/0221889/posters/ In case I need it later I would also want to know how to add the article title to the end of the URL like this (I'm using PHP): http://website.com/pelicula/0221889/the-article-name/ http://website.com/pelicula/0221889/the-article-name/posters/ Note: Stackoverflow method is also good for me, for example the url of this question is: http://stackoverflow.com/questions/3033407/htacces-to-create-friendly-urls-help-needed But you can put anything after the id and it will also work. like this: http://stackoverflow.com/questions/3033407/just-anything-i-want I have used some automatic web tools for creating the .htacces file, but its not working correctly. So I ask for your help. I will also be glad if you can recommend .htacces best practices and recommendations.. Thanks!

  • How to output multiple rows from an SQL query using the mysqli object

    - by Jonathan
    Assuming that the mysqli object is already instantiatied (and connected) with the global variable $mysql, here is the code I am trying to work with. class Listing { private $mysql; function getListingInfo($l_id = "", $category = "", $subcategory = "", $username = "", $status = "active") { $condition = "`status` = '$status'"; if (!empty($l_id)) $condition .= "AND `L_ID` = '$l_id'"; if (!empty($category)) $condition .= "AND `category` = '$category'"; if (!empty($subcategory)) $condition .= "AND `subcategory` = '$subcategory'"; if (!empty($username)) $condition .= "AND `username` = '$username'"; $result = $this->mysql->query("SELECT * FROM listing WHERE $condition") or die('Error fetching values'); $this->listing = $result->fetch_array() or die('could not create object'); foreach ($this->listing as $key => $value) : $info[$key] = stripslashes(html_entity_decode($value)); endforeach; return $info; } } there are several hundred listings in the db and when I call $result-fetch_array() it places in an array the first row in the db. however when I try to call the object, I can't seem to access more than the first row. for instance: $listing_row = new Listing; while ($listing = $listing_row-getListingInfo()) { echo $listing[0]; } this outputs an infinite loop of the same row in the db. Why does it not advance to the next row? if I move the code: $this->listing = $result->fetch_array() or die('could not create object'); foreach ($this->listing as $key => $value) : $info[$key] = stripslashes(html_entity_decode($value)); endforeach; if I move this outside the class, it works exactly as expected outputting a row at a time while looping through the while statement. Is there a way to write this so that I can keep the fetch_array() call in the class and still loop through the records?

  • Entity Framework 4.0 GetChanges() equivalent

    - by Jonathan
    Hi In LINQ to SQL, you can override SubmitChanges and use the method this.GetChangeSet() to get all the inserts, updates and deletes so that you can make last minute changes before it is committed to the database. Can this be done in EF 4.0? I see there is a override for SaveChanges but I need to know the equivalent for GetChangeSet()

  • Using a framework in a PreferencePane

    - by Jonathan
    Hi, i am currently trying to implement a "third party framework" (FeedbackReporter.Framework) into my preferencepane. Unfortunately I am getting the following error all the time when trying to launch my preference pane: 16.05.10 23:13:30 System Preferences[32645] dlopen_preflight failed with dlopen_preflight(/Users/me/Library/PreferencePanes/myPane.prefPane/Contents/MacOS/myPane): Library not loaded: @executable_path/../Frameworks/FeedbackReporter.framework/Versions/A/FeedbackReporter Referenced from: /Users/me/Library/PreferencePanes/myPane.prefPane/Contents/MacOS/myPane Reason: image not found for /Users/me/Library/PreferencePanes/myPane.prefPane As far as I read so far, this problem is probably caused because my prefPane is no actual app, but a "plugin" of "System Settings.app" and thus @executable_path resolves to a path within the bundle of this app, instead of the bundle of my prefpane. But I don't really picked up howto fix this problem. I guess it must be fairly easy since it should be a usual case that people use non-apple-frameworks in PreferencePanes. Thanks for your hints!

  • Login system and sessions (php)

    - by Jonathan
    I've created a login page and registration page and now I want to use that to password protect pages and have pages which show information specific to that user. Would storing the user ID of the user logged in in a Session variable be a safe and correct way of doing this? How easy would it be for a user to change the session variable to a different ID and access another user's information, and not having to type the users login details in?

  • JavaScript Key Codes

    - by Jonathan Wood
    I'm working with a JavaScript routine I didn't write. It is called from a text box's onkeydown attribute to prevent unwanted keystrokes. The first argument is apparently not used. The second argument is a list of characters that should be allowed. function RestrictChars(evt, chars) { var key; var keychar; if (window.event) key = window.event.keyCode; else if (e) key = e.which; else return true; keychar = String.fromCharCode(key); if ((key == null) || (key == 0) || (key == 8) || (key == 9) || (key == 13) || (key == 27)) // Control key return true; else if (((chars).indexOf(keychar) > -1)) return true; else return false; } This seems to work for alpha-numeric characters. However, characters such as . and / cause this function to return false, even when these characters are included in the chars parameter. For example, if the . key is pressed, key is set to 190, and keychar gets set to the "3/4" character. Can anyone see how this was meant to work and/or why it doesn't? I don't know enough about JavaScript to see what it's trying to do.

  • How to select random image of specific size using Django / Python?

    - by Jonathan
    I've been using this little snippet to select random images. However I would like to change it to select only images of a certain size. I'm running into trouble checking against image size. If I use get_image_dimensions() I need to use a conditional statement, which then requires that I allow exceptions. So, I guess I need some pointers on just limiting by image dimensions. Thanks. import os import random import posixpath from django import template from django.conf import settings register = template.Library() def is_image_file(filename): """Does `filename` appear to be an image file?""" img_types = [".jpg", ".jpeg", ".png", ".gif"] ext = os.path.splitext(filename)[1] return ext in img_types @register.simple_tag def random_image(path): """ Select a random image file from the provided directory and return its href. `path` should be relative to MEDIA_ROOT. Usage: <img src='{% random_image "images/whatever/" %}'> """ fullpath = os.path.join(settings.MEDIA_ROOT, path) filenames = [f for f in os.listdir(fullpath) if is_image_file(f)] pick = random.choice(filenames) return posixpath.join(settings.MEDIA_URL, path, pick)

  • open program once with multiple files as arguments from explorer

    - by Jonathan
    I have a program that works when, a file is opened with it using the right click menu in explorer. But if I select multiple files and then right click and open with my program then it opens multiple instances of my program, instead of just passing the multiple files as arguments to a single instance. The program is written in vb.net but is not a windows form, it is just a module, so I can to tick the Single instance option in the properties in Visual Studio. So how do I open multiple files from explorer context menu in a single instance.

  • Does Math.Sqrt cache its own results?

    - by Jonathan Beerhalter
    Someone has suggested to me that the built in C# Math.Sqrt function in .NET 4.0 caches its results, so that if I call Math.Sqrt(50) over and over again, it's not actually doing a sqrt, but just pulling the answer from a cache. Can anyone verify or deny this claim? If it's true then I have a bunch of needless caching going on in my code.

  • Animate/Ease an element to position when other elements disappear

    - by Jonathan
    Please take a look at this fiddle: http://jsfiddle.net/dhcyA/ Try clicking on a block. What I want is that when the other elements disapear, the selected block will animate/ease to his giving position instead of just jumping like it does now. Then the same animation repeats itself when clicking again on the box, but then back to place. Maybe to keep in mind: I'm using a reponsive design, which means those blocks can be vertical and horizontal after scaling the window. Any redevisions on the fiddle or suggustions would be great!

  • SQL -- How is DISTINCT so fast without an index?

    - by Jonathan
    Hi, I have a database with a table called 'links' with 600 million rows in it in SQLite. There are 2 columns in the database - a "src" column and a "dest" column. At present there are no indices. There are a fair number of common values between src and dest, but also a fair number of duplicated rows. The first thing I'm trying to do is remove all the duplicate rows, and then perform some additional processing on the results, however I've been encountering some weird issues. Firstly, SELECT * FROM links WHERE src=434923 AND dest=5010182. Now this returns one result fairly quickly and then takes quite a long time to run as I assume it's performing a tablescan on the rest of the 600m rows. However, if I do SELECT DISTINCT * FROM links, then it immediately starts returning rows really quickly. The question is: how is this possible?? Surely for each row, the row must be compared against all of the other rows in the table, but this would require a tablescan of the remaining rows in the table which SHOULD takes ages! Any ideas why SELECT DISTINCT is so much quicker than a standard SELECT?

  • Is it possible to embed C code in a C# project?

    - by Jonathan
    I know that it's possible to compile my C code into a dll, and then use P/Invoke to call that code. What I wondered if it was possible to have a chunk of C code embedded directly in my code, perhaps only available to one class... Something like this (non-working) example: public class MyClass { extern "C" { int do_something_in_c(int i) { return i*2; } } public int DoSomething(int value) { return do_something_in_c(value); } } I've been trying for a few hours using Visual Studio 2008, but I'm not getting anywhere, and I suspect that it isn't actually possible. Can anyone confirm or deny this? Thanks.

  • Paged UIScrollView with UIImageViews only showing first UIImageVIew

    - by Jonathan Brown
    I am working on a paged UIScrollView, but it only wants to show the first UIImageView within it. I add each UIImageView at an offset of the width of the scroll view, so that should create each page. When run, it says the scroll view is the right number of pages, but the images don't show. Any help would be much appreciated! int numSlides = NUM_TUTORIAL_SLIDES; NSString *fileName; UIImageView *slideImageView; CGRect slideFrame; for (int i = 1; i <= numSlides; i++) { slideFrame.origin.x = self.tutorialScrollView.frame.size.width * (i-1); slideFrame.origin.y = 0; slideFrame.size = self.tutorialScrollView.frame.size; slideImageView = [[UIImageView alloc] initWithFrame:slideFrame]; if([[AppManager sharedManager] is4inchScreen]) { fileName = [NSString stringWithFormat:@"Slide%[email protected]", i]; } else { fileName = [NSString stringWithFormat:@"Slide%[email protected]", i]; } slideImageView.image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:fileName ofType:nil]]; [self.tutorialScrollView addSubview:slideImageView]; [slideImageView release]; } self.tutorialScrollView.contentSize = CGSizeMake(self.tutorialScrollView.frame.size.width * numSlides, self.tutorialScrollView.frame.size.height); self.tutorialScrollView.delegate = self;

  • best way to store list of websites on iphone app

    - by Jonathan
    By best I mean most efficient. So don't go on about subjectiveness. I have a list of websites and I want to store the list on the iphone locally, there must be an URL, title and a small image (like 32x32 max image size). I don't think I should be using CoreData for this. Should I be using a plist?

  • Is it best to make fewer calls to the database and output the results in an array?

    - by Jonathan
    I'm trying to create a more succinct way to make hundreds of db calls. Instead of writing the whole query out every time I wanted to output a single field, I tried to port the code into a class that did all the query work. This is the class I have so far: class Listing { /* Connect to the database */ private $mysql; function __construct() { $this->mysql = new mysqli(DB_LOC, DB_USER, DB_PASS, DB) or die('Could not connect'); } function getListingInfo($l_id = "", $category = "", $subcategory = "", $username = "", $status = "active") { $condition = "`status` = '$status'"; if (!empty($l_id)) $condition .= "AND `L_ID` = '$l_id'"; if (!empty($category)) $condition .= "AND `category` = '$category'"; if (!empty($subcategory)) $condition .= "AND `subcategory` = '$subcategory'"; if (!empty($username)) $condition .= "AND `username` = '$username'"; $result = $this->mysql->query("SELECT * FROM listing WHERE $condition") or die('Error fetching values'); $info = $result->fetch_object() or die('Could not create object'); return $info; } } This makes it easy to access any info I want from a single row. $listing = new Listing; echo $listing->getListingInfo('','Books')->title; This outputs the title of the first listing in the category "Books". But if I want to output the price of that listing, I have to make another call to getListingInfo(). This makes another query on the db and again returns only the first row. This is much more succinct than writing the entire query each time, but I feel like I may be calling the db too often. Is there a better way to output the data from my class and still be succinct in accessing it (maybe outputting all the rows to an array and returning the array)? If yes, How?

  • CakePHP ACL use case(s)

    - by Jonathan
    I have got a simple web app in development, i want to establish a couple of user groups; Admin, Doctors & Patients. Each group would have their access restricted to particular controller actions rather than individual content. So for example, Doctors can view patient records (index & view actions), but cannot delete them. Usually i would create a groups model, and assign the various users to a group. And filter in the beforeFilter() method to determine if the user has access. But if ACL can do the job, why right the code, right? Thanks

  • "pay if you want to" using in app purchases (iphone)

    - by Jonathan
    I realise that you can't use in app purchases for real things. But does an in app purchase actually have to give extra functionality in the app. Can it be used to have optional paying? I've made an app that really should be free but I'd like to make a little money even if it's only one 59p. So could I have an in app purchase which users can click to pay if they want to. it might sound stupid but I'm betting there is at least one person who would becase they are nice :)
