  • Using the apostrophe for PHP associative array element's name

    - by Haskella
    Hi I've been trying to figure out how to put something like Joe's Fruits into a PHP array something like this: <?php $arr = array( 'Fruitland' => '3ddlskdf3', 'Joe's Fruits' => 'dddfdfer3', ); ?> Using the above for example (stackoverflow's code color should tell you this by now), the array will take it as 'Joe' between the two apostrophes instead of the whole 'Joe's Fruits' is there any way I can do this without just calling it 'Joes Fruits'?

  • "The image <name> cannot be displayed because it contains errors" when using pchart Render method

    - by christophe-milard
    Hi, I am trying to use the pchart package (over php) to build (and directly display) graphs/charts. At this time, I am just trying to run their provided example (Example1.php), where I just have replaced the final: $Test-Render("example1.png"); by $Test-Stroke(); But When I do this, I get:" The image cannot be displayed because it contains errors" on the browser. If I leave the original "$Test-Render(...)" the generated image is OK. (but not sent) I have read that there is (was?) an issue with mozilla/Firefox browsers regarding images being required twice and the REFER URL, but when I browse at the pchart home page, I can use their "sanboxes" and get the result of my tests directly displayed on my browser (http://pchart.sourceforge.net/demo.php). ... So their must be a way (or a nice work around) to send the generated graphs directely to the browser successfuly. If your answer is to generate the image (i.e. use Render) and then send it afterwards, please but accurate on how to do this (how do I destroy the generated files automaticaly, permissions...) I am new to this, sorry advance if it's obvious...;-)

    - by xckpd7
    I want to take an array like this: var food = [ { name: 'strawberry', type: 'fruit', color: 'red', id: 3483 }, { name: 'apple', type: 'fruit', color: 'red', id: 3418 }, { name: 'banana', type: 'fruit', color: 'yellow', id: 3458 }, { name: 'brocolli', type: 'vegetable', color: 'green', id: 1458 }, { name: 'steak', type: 'meat', color: 'brown', id: 2458 }, ] And I want to create something like this dynamically: var foodCategories = [ { name: 'fruit', items: [ { name: 'apple', type: 'fruit', color: 'red', id: 3418 }, { name: 'banana', type: 'fruit', color: 'yellow', id: 3458 } ] }, { name: 'vegetable', items: [ { name: 'brocolli', type: 'vegetable', color: 'green', id: 1458 }, ] }, { name: 'meat', items: [ { name: 'steak', type: 'meat', color: 'brown', id: 2458 } ] } ] What's the best way to go about doing this?

  • Nice name for `decorator' class?

    - by Lajos Nagy
    I would like to separate the API I'm working on into two sections: 'bare-bones' and 'cushy'. The idea is that all method calls in the 'cushy' section could be expressed in terms of the ones in the 'bare-bones' section, that is, they would only serve as convenience methods for the quick-and-dirty. The reason I would like to do this is that very often when people are beginning to use an API for the first time, they are not interested in details and performance: they just want to get it working. Anybody tried anything similar before? I'm particularly interested in naming conventions and organizing the code.

  • Calling AddEventListener in a loop with a variable element name

    - by user302209
    Hi, I'm trying to do the following: I have a set of images and select (dropdown) HTML elements, 30 of each one. I'm trying to use AddEventListener on a loop from 1 to 30 so that when I change the value of the select, the image src is updated (and the image changes). The AddEventListener function is this one: function AddEventListener(element, eventType, handler, capture) { if (element.addEventListener) element.addEventListener(eventType, handler, capture); else if (element.attachEvent) element.attachEvent("on" + eventType, handler); } I tried this and it worked: var urlfolderanimalimages = "http://localhost/animalimages/"; var testselect = "sel15"; var testimg = "i15"; AddEventListener(document.getElementById(testselect), "change", function(e) { document.getElementById(testimg).src = urlfolderanimalimages + document.getElementById(testselect).value; document.getElementById(testimg).style.display = 'inline'; if (e.preventDefault) e.preventDefault(); else e.returnResult = false; if (e.stopPropagation) e.stopPropagation(); else e.cancelBubble = true; }, false); But then I tried to call it in a loop and it doesn't work. The event is added, but when I change any select, it will update the last one (the image with id i30). var urlfolderanimalimages = "http://localhost/animalimages/"; for (k=1;k<=30;k++) { var idselect = "sel" + k; var idimage = "i" + k; AddEventListener(document.getElementById(idselect), "change", function(e) { document.getElementById(idimage).src = urlfolderanimalimages + document.getElementById(idselect).value; document.getElementById(idimage).style.display = 'inline'; if (e.preventDefault) e.preventDefault(); else e.returnResult = false; if (e.stopPropagation) e.stopPropagation(); else e.cancelBubble = true; }, false); } What am I doing wrong? I'm new to JavaScript (and programming in general), so sorry for the vomit-inducing code :(

  • Slug ID's with the same name?

    - by James Jeffery
    I want to create slug URL's from a users title in my system. If a user types "The best way's to get slim; period!", then I want the slug to be "the-best-ways-to-get-slim-period". Also, if someone has already created a page with that title I want the slug to be "the-best-ways-to-get-slim-period-1". My question is how can I check the database before a record is created? Ok, obviously I am going to have to perform a check in the database, and then a write. That's 2 queries. Is this the normal way to do it? Also, are there any conventional regular expressions for filtering non alpha/number characters and replacing spaces with hyphens? Any help is much appreciated. Thanks.

  • Jackson XML globally set element name for container types

    - by maxenglander
    I'm using Jackson 1.9.2 with the XML databind module. I need to tweak the way that Jackson serializes arrays, lists, collections. By default, with an int array property called myProperty containing a couple numbers, Jackson / XML is producing the following: <myProperty> <myProperty>1</myProperty> <myProperty>2</myProperty> </myProperty> What I need to produce is: <myProperty> <item>1</item> <item>2</item> </myProperty> I can do this on a per-POJO basis using a combination of JacksonXmlElementWrapper and JacksonXmlProperty like so: @JacksonXmlElementWrapper(localname='myProperty') @JacksonXmlProperty(localname='item') public int[] myProperty; This solution, however, would require that I manually apply these annotations to every array, list, collection in my POJOs. A much better solution would allow me to apply a solution once, globally, for all array, list, collection types. Any ideas on how to implement such a solution? Thanks!

  • C# double-quoted path name being escaped when read from file

    - by KrisTrip
    I am trying to read in a text input file that contains a list of filenames (one per line). However, I am running into an issue if the user double-quotes the path (because it has a space in it). For example, a normal input file might have: C:\test\test.tiff C:\test\anothertest.tiff C:\test\lasttest.tiff These get read in fine by my code ("C:\\test\\test.tiff" etc) However, if I have the following input file: "C:\test with spaces\test.tiff" "C:\test with spaces\anothertest.tiff" "C:\test with spaces\lasttest.tiff" These get read in double-quotes and all ("\"C:\\test with spaces\\test.tiff\"" etc). This becomes a problem when I try to open the files (I understandably get invalid character exceptions). My question is, how do I fix this? I want to allow users to input quoted strings and handle them correctly. My first impression was to just write a little method that strips off beginning or ending quotes, but I thought there might be a better way.

    Hi, I have a native app that has an .OCX file that needs to be registered for it to be used in a .NET application. Now currently there's different versions of this .OCX on the machine. Can someone please explain how this can affect the registration of this new (updated) .OCX file registration? And how does my .NET app know which object to create from which .OCX file?

  • How to assign the array key a value, when the key name is itself a variable

    - by Matrym
    How do I identify an item in a hash array if the key of the array is only known within a variable? For example: var key = "myKey"; var array = {myKey: 1, anotherKey: 2}; alert(array.key); Also, how would I assign a value to that key, having identified it with the variable? This is, of course, assuming that I must use the variable key to identify which item in the array to alert. Thanks in advance!

  • Code Golf: Numeric Equivalent of an Excel Column-Name

    - by Vivin Paliath
    Can you figure out the numeric equivalent of an Excel column string in the shortest-possible way, using your favorite language? For example, the A column is 1, B is 2, so on and so forth. Once you hit Z, the next column becomes AA, then AB and so on. Rules: Here is some sample input and output: A: 1 B: 2 AD: 30 ABC: 731 WTF: 16074 ROFL: 326676 I don't know if the submitter is allowed to post a solution, but I have a Perl solution that clocks in at 125 characters :).

  • How to specify a SEO friendly url like twitter www.twitter.com/<name> using YII framework

    - by hip10
    Hi, I am currently using the Yii framework, and I would like to know if anyone has any clue on how to setup a SEO friendly url like www.twitter.com/ automatically in Yii? I know how to do so this manually in the config/main.php but I would like to be able to dynamically generate it. I have been able to do it in Grails as well. In Yii, what I know of is that you need to have another parameter like www.twitter.com/l/, but I do not want that parameter, anyone can share? Thanks.

  • Using same name for Core Data object as a Private Framework Object

    - by bjorn geez
    Hi all, I've got a core data-based app for iPhone and I'm getting the following warning: objc[2472]: Class Property is implemented in both /System/Library/PrivateFrameworks/Notes.framework/Notes and /var/mobile/Applications/B69194FF-448F-48AD-A78D-DDB8935F/AmcCalc.app/AmcCalc. One of the two will be used. Which one is undefined. When I started working on this app back with SDK 3.0 I didn't get this error, so how do I deal with this? Thanks! Bjorn

  • Declaring object type as NSManagedObject or class name

    - by Don Fulano
    In Core Data, if I have a Person entity is there any difference between: NSManagedObject *aPerson = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:[self managedObjectContext]]; or Person *aPerson = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:[self managedObjectContext]]; Should aPerson be of type Person or NSManagedObject? Is there a difference?

  • PHP Key name array

    - by Sean McRaghty
    I have an array $data fruit => apple, seat => sofa, etc. I want to loop through so that each key becomes type_key[0]['value'] so eg type_fruit[0]['value'] => apple, type_seat[0]['value'] => sofa, and what I thought would do this, namely foreach ($data as $key => $value) { # Create a new, renamed, key. $array[str_replace("/(.+)/", "type_$1[0]['value']", $key)] = $value; # Destroy the old key/value pair unset($array[$key]); } print_r($array); Doesn't work. How can I make it work? Also, I want everything to be in the keys (not the values) to be lowercase: is there an easy way of doing this too? Thanks.

  • Method name collision in interface implementation - Java

    - by Bhaskar
    If I have two interfaces , both quite different in their purposes , but with same method signature , how do I make a class implement both without being forced to write a single method that serves for the both the interfaces and writing some convoluted logic in the method implementation that checks for which type of object the call is being made and invoke proper code ? In C# , this is overcome by what is called as explicit interface implementation. Is there any equivalent way in Java ?
