Actionscript 3.0 :: Zendamf Not Handling Special Character Data
May 29, 2009
I've written an application that deals with multiple languages, English, French, etc, I'm using Zendamf to retrieve multi-language data from a database, however, I'm running into a problem using Zendamf, and it could kill this project fast:
There seems to be an issue passing special character values via Zendamf. While querying a database that returns data including French-text characters (ie: Québec), the result returned from Zendamf is not handling the special characters (ie: instead of Québec, we receive Qu�c).
I've checked the output of the data via Php: the issue is not with the database result - the characters are returned correctly from the database to the Php result-set - I am able to print these characters correctly before they are sent through Zendamf, either by rendering them in HTML or by writing them to a log file.
However, once I plug the SQL result into an object and pass it to Zendamf, the special characters get mangled. Using Charles Web Debugging Proxy, I can see that the result values are mangled before they are passed back to my AS3 application.
i am currently trying to learn ZendAMF, but i have a hard time troubleshooting which makes learning it quite hard. Is there a way to make the PHP file throw an exception that gets traced as an error message in AS3 (not Flex), the only error i seem to be able to get is "Error #2044: Unhandled NetStatusEvent:. level=error, code=NetConnection.Call.Failed", but it tells me jack ****.
i have gotten ZendAMF working, i just want to know how i can make error handling better, so that as an example can use PHP to tell flash that no results were found, or that the typed text was invalid. Is it better to use AS3 to check if the field was filled properly?
We have faced one problem while using the special character � in flash. If we are using this character, it will not show in the flash. We are generating the flash content dynamically with a php backend.
I am making a drag and drop type of quiz. The text is loaded from an XML file. I am looking for a way to "detect" a blank in the text which represents the point in the sentence where a word needs to be filled in. And then that point needs to be represented by a movieclip or sprite or something that will hold text from the word that is dropped onto it (it will need to be draggable in case the user changes thier mind).
I am using a ready made PHP form ( i cant edit it), and i should pass the following variables from flash: t[name] t[email] But unfortunately flash does not support these characters "[" "]".

I'm using regular expression to search word in a string, for example
var patrn:RegExp = new RegExp("\bit's\b"); var str:String = "Heres my problem in it and it's so help me guys."; trace(patrn.exec(str)); //result is null
My problem is I can't search the data in a string which has special character like ('/,/.). What regular expression string is capable solving my problem?
My dynamic textfield doesen't show special characters (%&+...). I have emped the font(uppercase, lowercase, numerals, PUNCTUATION and basic latin) and I've also tried to render it as html.for example:flash.addVariable("newtext"," Word & word2");AC2myTextfield.text = _root.newtext;then it prints just "word", because flash doesen't understand character & as a text format;locally it worked finemyTextfield.text = "Word & word2;";
i'm trying to display this character "<" from an external txt file. Some how it doesnt work. I know that for some characters you have to change the code, examples if you want to display "+" you have to change it to %2b. I read in adobe.com that for "<" you have to change it %3c, and yet it doesnt work.
I've build a guestbook in flash, which works together with a PHP file and a textfile. The problem is that the guestbook doesn't show any special characters... In the textfile they do appear, but not in the flashfile... So flash uploads the text fine, but when it want to download the text...it leaves all the special characters out...
I'm building a sidescrolling world where you can move around.The idea is that you should be able to move to any point in the world, as well as travelling really fast.I'm pregenerating a long list of data about objects to place, their positions etc.
Now. When moving to a point far away from current position I don't want to loop through the whole list of objects to find what objects should be seen and not, so I'm thinking I should divide the position list into sections, each covering an area equal to the visible area. That way I would only have to roll through the lists closets to the new position.This would however result in an array of thousands of elements each consisting of about 20 objects and I'm figuring that might not be very healthy.One solution would be to split everything up further so that in the end I would have a handable nr of arrays containing a handable nr of elements.
You're probably thinking I should generate positions on the fly, but since one place in the world can be revisited I need to store all positions.
I've run into some problems trying to handle large text files in AIR (300+ MB in size). I can open a filestream and read the file just fine and even store it into a string variable. the problem occurs when i try to manipulate this data. Im trying to get each line as an element in an array so i can manipulate this data.Here's what i've tried:1. read the file into a string variable and perform a split looking for the newline character ). this freezes the program2. i've tried reading the file in one byte at a time and putting each line into an array AS it is being read from the filestream. This not only takes long but eventually freezes.
3. i've tried splitting the final string variable which contains the entire text file into chunks to process it separately.4. i've even tried putting the file contents into a sqlite database, but this also freezes.At this point, im not sure what my options are. Is AIR even equipped to manipulate data at this level? I could use a point in the right direction
I found out that if XML file's attribute contains German special chars (chars with umlaut, like:..) then I get "undefined" answer when I try to read an attributes value. I tryed to change XML file encoding to: "UTF-8" and "iso-8859-1" but still no luck. "system.useCodepage = true;
I have a dynamic text field in Flash CS4 which gets its value via XML from a back-end MySQL database. The issue is that I want to make the text field to display HTML text
However, there is a problem in Flash both AS2 & AS3 and both CS3 & CS4 in the sense that when there are special characters ie: double quotation marks ", the XML loader does not read (retrieve) any data from the database.
How can I suppress these special characters ? How can I find a workaround ?
I'm loading external data from a txt file into a MovieClip. It contains data that is crucial to the presentation viewing. It is necessary to load, not right away but at some point (the sooner the better). When the txt is on the same server it works instantly, but I'm loading data from another server.
Two problems: the onLoad code is stuck if the file doesn't load (connection problem, server down?) and in offline mode what happens if the data is purged out of browsers cache (history problem)?
How can i handle these exceptions?
1. Some code that uses a "timer" to periodically try to load the data again if the connection is slow and the txt doesn't loads the first time?
2. When it doesn't load at all, and the onLoad fails, how can I simulate notOnLoad - exception for data download fail? And retry the dataLoad?
I've already made cross-server data loading possible using crossdomain.xml policy.
The site is still in development. This problem occurred when the server which contains the data.txt was down due to maintenance, and when one of the test-visitors was downloading so much in the background that his connection didn't had enough bandwidth to load data correctly (browser thought he had connection problems).
I need to make a function that creates an object based on each set of data in an XML file. I am currently using bracket notation to do it, but don't know how to increment the next object's name dynamically. I wanted to do something like this:
I've got a dynamic text area pulling text from a MySQL database via AMFPHP.The text includes special characters such as accents,umlauts, etc (multi-language site platform). Most of them work fine, and ALL of them work fine when I'm on a Mac client. However, if I use a Windows client machine in either Firefox or IE6, there are a couple characters that for whatever reason just don't seem to show up-instead I get the [] box character.
The only characters I've found that seem to be affected like this are European quote characters like ' " and " (hex characters 146, 147, 148). I'm using the familiar ampersand-pound-number-semicolon escape sequence for them. And like I said, they all display fine on Mac/Firefox and Mac/Safari. Why are all my other special characters (umlauts, accents, etc) working fine and just these things failing? It's also worth noting that they look fine if I dump them out to a PHP file and pull it up in a browser...
I have just established a menu based-image in flash in the main html page. Also I do have a second page has details on each option of the menu of the main page. I am trying to whenever I click on any option of the menu in the main page; this should take me to the specific section in the second page describing this option.
For a client, I am working on a project where a live RTMP stream is published to an Adobe FMS 3.5.6 server from a java application, using Red5 0.9.1 RTMPClient code. This works fine, until the timestamp becomes higher than 0xFFFFFF after 4.6 hours, and the RTMP extended timestamp field starts being used. I have already found: when the extended timestamp was written after the header, the last 4 bytes of the data were being cut off. I have fixed this locally, and now the data being sent seems to me to be conformant to the spec. However, FMS still throws an error message in the core log and then kills the connection from the Red5 client. Here is the error message:
I've worked with AMFPHP for a while, but with Adobe supporting ZendAMF, I was wondering if I should migrate.
One of the major disadvantages for AMFPHP is that class mappings need to be public, so not only does that mean public members on the PHP side, but also on the Flex side. I was wondering if it is the same case for ZendAMF.
I am using ZendAMP php and Flex (Flash Builder 4). It works great, but I noticed when I am looking at the traffic going between my flex application and ZendAMF, there packets moving even though I am not requesting communications in my code.For example, this is what my service looks like in flex:
var activityLogService:RemoteObject = new RemoteObject("zend"); activityLogService.showBusyCursor=true; activityLogService.endpoint="http://myserver:80/amf/";[code].........
Are these just some kind of 'keep alive' messages?If so, is there a way to turn them off? Also, if so, is there a way I can use them to keep some kind of session alive on the server side maybe (maybe that's what they are for)?
Whats the scoop?I watched Lee's tutorial on Zend and also the older ones for AMFPHP.Is one 'better' than the other? Doubt that since as I understand both are written by the same author, only Adobe 'officially' supports Zend.
My application is composed of 3 parts
1-an image editing tool allowing users to upload images, edit them, then post them to a server.
2-a publicly viewable gallery
3-a private 'admin' tool allowing the user to change their login settings and delete any uploaded images.
Are both Zend and AMFPHP equally robust and easy to implement when it comes to session registration and login?
I am using ZendAmf with an example Tutorials of Lee and files downloaded from this forum.
This is the client actionscript code : Code: Select allvar nc:NetConnection = new NetConnection(); nc.connect("http://localhost/myfiles/zendTest.php"); var res:Responder = new Responder(onResult,onError);
