Flex :: Zend Amf - Display Results In Different Labels
Apr 11, 2011
I've got a simple app that is currently getting information form a database and just displaying the content into a datagrid.
Instead of having this information displayed in a datagrid, I'd like to display it in a couple of labels (first name, last name, phone, etc.), but I'm not really sure how to.
Currently on creationComplete I call my php query function - which looks like this.
public function getPeople() {
return mysql_query("SELECT * FROM tbl_people ORDER BY pers_name ASC");
}
[Code].....
Eventually my query will be modified and will only ever return 1 row from the database. So how do I get the results to display in labels instead of the datagrid?
I have an AdvancedDataGrid with a custom label function whose value can change based on other form status (specifically, there's a drop down to choose the time display format for some columns).Right now, I have this labelFunction:
internal function formatColumnTime(item: Object, column: AdvancedDataGridColumn): String { var seconds: Number = item[column.dataField]; return timeFormat.selectedItem.labelFunction(seconds); }
[code]....
... and the timeFormat object is a combo box with items whose labelFunction attributes are formatTimeAsFractions and formatTimeAsInterval.The columns that have time formats have formatColumnTime as their labelFunction value, because extracting the seconds in that function and passing it in to the formatters made for a more testable app (IMHO).
when the timeFormat.selectedItem value changes, I want to force my grid to re-calculate the labels of these colums. What method must I call on it? invalidateProperties() didn't work, so that's out.
would go about setting up flash to display results returned by a SQL query one at a time.I can work out the query and PHP, but want I want to know is how to make flash take each one and animate it, including pausing and clearing the screen when full, then continuing on a 'new' screen. It's basically for displaying a list of events in a database.
I have been looking for a tutorial that shows or explains how to display the contents of a search engine like 'Google' or 'Youtube' inside Flash. No luck so far...
I am working in Flash 8 and using AS 2.0 coding. I am working with page flipping application. Here I have an option "search". I will tell you the scenario. Here I am loading images/pages dynamically thru an xml. It was loading and working like a page flipping. so far it was done. Now if you enter some text inside the search option and press the button, it has to search for all the loaded images/pages and has to display the resulted pages. How this functionality has to done. How to search the jpg's with a given string?
I've been searching for the last couple days but can't seem to find a basic example of what I'm looking for. I'm developing a Flex 4.5 app and in it I have a viewstack of 2 components that use some of the same services. Currently the only way I can get the app to correctly use the web services is by defining 2 different web services that use the same PHP web service file. For example: I have an app, and within it I have a viewstack with tab navigation of 2 components: #1) retrieve a list of all Salary Employees, and #2) retrieve a list of all Contractors. Currently to get it working I am defining a UsersTableEmployees webservice within component #1 and a UsersTableContractors webservice within component #2, but they both point to the same PHP class, and only differ in the arugment value I pass to them. Ie, getUsers("employee") and getUsers ("contractors"). Of course this is not best practice.
Searching StackOverflow and Google gives me many results about ColdFusion and MVC (example What's the best way to share data between components in Flex?), but I'm still confused. Can anyone here point me to a basic example (even sample MVC) and source code of an app that uses Zend AMF and allows different components to call common web services?

I need to show the results in my flash program. The results are working great in a trace. I get the text to show, but not the results from high1.lab, high2.lab and high3.lab.
I've made a query in PHP, and I'm trying to send the results back into Flash via AS3, but it's throwing up this error...
Error: Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs. at Error$/throwError() at flash.net::URLVariables/decode() at flash.net::URLVariables() at flash.net::URLLoader/onComplete()
Here is the relevant part of the PHP and AS3 code, including the query. The Flash variable rssAdd is passed over to the PHP which is using it in the PHP query accordingly. $url = $_POST['rssAdd']; $query= SELECT title FROM Feed WHERE category = (SELECT category FROM Feed WHERE url =$url) AND url!=$url; $result = mysql_query($query); echo $query;
Here is the AS3 code I've done so far. function recommendation(){ var request:URLRequest = new URLRequest("url"); request.method = URLRequestMethod.POST var recVars:URLVariables = new URLVariables(); [Code] .....

I am trying to adapt this search code to display the results one at a time.Right now it displays all the terms it finds all at once and separated by commas. How would I adapt the code so it displays one item or term at a time.
I am trying to create an array (1-35), mix that array and display the results with a trace. I am getting an error with the following code.
public function generateArray(toNumber : int) : Array { var result : Array = []; for (var i : int = toNumber; i != 0; i--) { result.push(i); [Code] .....
The error(s) are: 1180: Call to a possibly undefined method generateArray. 1120: Access of undefined property generateArrays.
Is it possible for recent versions of flash to directly (or thru Php) access (& update) data from a mysql database and display results based on the data?
So if my database were like this (math scores):User 13Jerry | 20Kane | 7 the flash output would be a bar graph like this (those hyphens would be bars in flash)
Is this possible these days? Google analytics does something like similar to this.
I last used flash somewhere in 2003/4. Never after that :-) I've completely lost touch.
I have a Flex-Page which connects to a MySQL-DB through PHP (Zend). I run the Flex-Page on an IIS-Server (Windows Server 2008 R2) and it works. But the problem is, that i specified the web root to the C:inetpubwwwroot directory (there php is running). On the server i want it on another directory.(Now i have the main Flex Page in the directory für the webserver, and the php files are in the wwwroot directory).
When i specify the web root to an other directory, nothing works, not even on my local machine.
i am using Flash CS4 (AS3) + AMFPHP + MySQL to do own flash frontend for Wordpress CMS. Everything is going fine but i`ve got one problem. Problem with properly display of result of query in AS3 by using ArrayCollection.
When i check my service in "amfphp/browser/" in web browser i`ve got this (with all needed data):
I know that "result" is an ArrayCollection type but i don`t know how to get rows and columns from this. I know that my data is there but i have no idea how to get it.
how to get to Arrays and simple data variables which are in ArrayCollection.
P.S. I tried also change query type in service.PHP for mysql_fetch_query but in that case i`ve got only one row (not all data).
I am working on a search function but am having a bit of trouble finishing some display details. The following code works fine for finding and displaying text within an xml file, but I want to display the results differently. Using the following xml as a source, I would like to:- highlight the search term (var searchTerm) in red when found in the xml- add some characters found before and after the search term to give the term that is found some contextFor now, how could I add 3 characters before and after the search term, like so: "The first tex" - and highlight 'first' in red
I'm working on a school assignment in which I have to make a basic CRUD (create, read, update and delete) content management application using the Zend AMF framework in FLEX.Basically I create a mock database and have flex print the data from the database into a data-grid. I need to also have an add form, edit+update feature and delete feature. As of now I have FLEX printing all the database info into my data-grid and my add form works as well as my delete button. My problem is I cannot get the update function/query to work. You know:
(UPDATE myTable SET valueName='".$variable."')
What happens is I have it programmed so that when you click on any row in the data-grid, the information is printed back into the add form. Here you can change the values and hit the 'update button' (not the add button) to run the update query on the php file.So my mxml looks something like this:
So basically I can send the ID over to the PHP but not other values along with it, in this case the date time and name. How can I send over these edited values so the update function actually updates them?I'm assuming my update function is wrong in either the mxml or the php or both.
I have a Flex frontend connecting via RemoteObject to Zend Framework's Zend Amf. This is my only means to transport data between client layer (Flex) and the application and persistence layers (LAMP with Zend Framework).Some ways I can address security are as follows:
I can address TLS by using mx.messaging.channels.SecureAMFChannel in my services-config.xml file and ensuring Flash player is loaded into a HTTPS wrapper and is in fact using HTTPS since the AMF protocol is layered on top of HTTP RemoteObject has a setCredentials method with which I can pass AMF authentication headers to protect user related data. Assuming TLS was actually secure I can expose methods on the endpoint after authenticating the User.I can protect against cross-site scripting and other FLASH vulnerabilities with a properly set up crossdomain.xml how to I protect my endpoint against another AMF consumer? For instance, if there were another AMF consumer (not Flash so not bound by crossdomain.xml and Flash sandbox security) other than my Flex client that knew my endpoint, what would stop it from using methods that the endpoint exposes?
As far as I know I essentially need a way to authenticate my Flex application against my Zend Amf endpoint. After AMF consumer authentication, I have some of the security mechanisms I mentioned above to protect certain pieces of data (like User authentication). I can not embed some sort of authentication mechanism into my Flex swf because the swf is vulnerable to decompilation (the swf can not be trusted). While sensitive data is protected via User authentication the unprotected data is hardly public but as far as I can tell is totally open for public consumption.
i have a question about Zend Framework and mainly the model part. I know there is no abstract model class and understand why. I red a lot of blog posts about it, but couldn't find any example that would clearly explain it to me. I'm building a very basic application. Lets imagine we have just three tables.company(ID, name, street, streetNo, Town), meta(ID, name, description), company2meta(ID, companyID, metaID, value, note). All types of realtionship are there (1n n1, nm). The a need also services (amf) with Value Objects. So, here is what I think:
I have a datagrid that loads content from a database. Once the data has been loaded I have a function that has selectedIndex=0; Right after that I call another function that tries to display the selected item across a couple of labels. The problem is nothing loads in the labels unless I run the functions twice. I'm guessing its some sort of data race problem where the item hasn't been selected by the time the function that displays the items in labels runs. How can I get the item to be selected before the next function runs.
I am using Flex and php to develop my project. Everything works great in my local machine.However, when I upload my files to my serverI got the error when loading my flex application.The pop-up error message is
I'm working on a new project in Flex with a CakePHP backend and since I'm using Mate, I wanted to use the RemoteObject stuff it does to call CakePHP.First I tried just doing one call at a time in CakePHP but I saw that that would mean a lot of endpoints, so I looked into some like amfphp for cakephp. I saw that Zend AMF is now the successor to AMFPHP so I wanted to try to integrate it.
I probably spent 8 hours on the final solution that is probably 10 lines of code.So without further ado I give you FlexibleCake: a CakePHP controller that acts as an AMF Endpoint and is able to instantiate and call any controller / method. I also built a "tester" or "explorer" app that allows you to send requests to the end point and visualize the result.

PS there where some changes I had to make to the core CakePHP classes to make it work. It only involved modifying the comments in the model.php class I believe (since Zend AMF reads the comments to gather metadata for the functions called).
In flex (flash builder 4) I have a Date() property that I am passing to Zend AMF (php) and I want to store that (as well as other data) in mongoDB. Mongodb is complaining about the date because it comes across as a Zend_Date object, which appears to be an object containing several properties and Mongodb is saying that it can not accept blank properties. So, I take that to mean it needs to be converted to something else before I can store it? If so, how do I do that?
At the moment I have taken the approach of converting the Zend_Date object in to a date string to store it (in php): $object->readyDT=date("m/d/Y H:i", strtotime($object->readyDT)); //convert to string
That works fine, and I have a string in mongodb of that date. Now, when I load the date from MongoDB, I need to convert it back to a Zend_Date so it properly converts back in to a Date() object in flex (I have to check that it's not blank or it throws errors in php): if (isset($object->readyDT) && $object->readyDT!=="") $object->readyDT = new Zend_Date($object->readyDT, 'MM/dd/yyyy hh:mm');
This all works, but it seems like there should be a much easier way to take a Date() from flex and get it stored in MongoDB via Zend AMF/PHP. ?
I followed the instructions in this tutorial to set up Zend AMF as a way of passing data from my flash app to my PHP app:So I have the directory structure and everything as described there. This is my gateway controller:
class Gateway extends CI_Controller { function __construct()
I'm using Zend AMF to send my remote objects to Flex. I've defined a Constant class and created getASClassName() method. Then I've created Action script class in flex.
Objects are send successfully, but they are deserialized to generic Objects in Flex instead of specific ones. EDIT: On network monitor in Flex I can see that AMF value is set to com.my.project.valueobjects.Constant. Although array from event.result contains Objects.
im completely lost on how to do a simple multiline label. The docs say that labels are best used as single lined elements, but that alludes to it being able to do multiline if necessary. Anyone have any clarification on the subject?
