Php :: Find Users Residing Between A Specified Distance (using User's Zipcode)
Aug 4, 2010
Is there a way to find the radial distance using the zipcode? My task is to search the all the users residing with in a specified distance. I know the zipcodes of the users. Eg, users between 25 miles from the current location. I have other search categories, for which i am using mysql queries. I am unable to figure anything out for the distance issue.
My backend is in php
and frontend in Flex.
The best option for me would be something like that of www.zip-codes.com/zip-code-radius-finder.asp. ie, if I should be able to get all the zip-codes available in the specified radial distance. So i can compare this zip-codes to the users zip-codes in my database. And select the ones with a match.
I am rotating an object with TweenLite, however instead of a set duration I want the duration to be based upon the distance of rotation where 180 degrees = 3 seconds 90 = 1.5 and so on. Here is my attempt to find the distance of rotation:
var time:Number = Math.abs(Math.atan2(Math.sin(angle-wheelObj.rotation),Math.cos(angle-wheelObj.rotation)); TweenLite.to(wheelObj, time, {shortRotation:{rotation:angle}, ease:Expo.easeOut, onComplete:rotateWheel, onCompleteParams:[target]}); TweenLite.to(carObj, time, {shortRotation:{rotation:angle}, ease:Expo.easeOut});
This just isn't working, time is sometimes huge when the rotation is small and sometimes tiny when it is big, so does anyone know a better way to do this?
This code calculates the distance between 2 points by using distance formula, Math.sqrt ( (x1 - x2)^2 + (y1 - y2) ^2). My first point has mmx and mmy coordination and second one has ox and oy coordination. My question is simple, is there any FASTER way for calculate this?
How could I find the distance between a given point and a drawn line? I was thinking about using the point-slope formula to draw a perpendicular line between the point and the line and measuring it as the distance, but I'm not quite sure how to do this in as3.
How does Flash use Math.sqrt to get the distance between 2 movieclips? In the example the only givens are 2 points along a triangle:
function getDistance(x1:Number,y1:Number,x2:Number,y2:Numbe r):Number { var dx:Number=x1-x2; var dy:Number=y1-y2; return Math.sqrt(dx*dx+dy*dy); }
dx is the difference between the x coordinates of 2 points/2 mc's dy is the difference between the y coordinates of the same 2 points the Math.sqrt is the Pythagorean theorum
If the Pythagorean theorum is a^2+b^2=c^2 for the sides of a triangle how do 2 points achieve the same result if the lengths of the sides aren't given?
I created a movie where I have a circle in the middle and a line drawing from the center out when the mouse moves. I want to calculate the distance from the mouse position to the middle of the circle. What I am going to do is have a sound playing from the center of the ball..The closer you get the louder the sound gets and the further away from the middle the quieter it gets. You can download my fla to see what I have so far.
So, right now when I want to find the distance between two points, I go: dist = Math.sqrt((this_x-that_x)*(this_x-that_x)+(this_y-that_y)*(this_y-that_y)) BLECH! I don't want to do that every time. So I want to make a nice little function that I can apply to an object. Problem is, I don't know how to do this. Is it possible to end up with something as easy as: Math.dist(thisclipname, thatclipname)? How do you guys set up functions that do bulky math and return nice clean numbers?
i have made a chat app and i want to let the user add another users that he can find by searching the database of users to his own list, and grouping them ,,, this is can be done but ,,, now in my app when the user connect to the lobby he get all the online connected users in his list i mean when connecting to the online user list sharedobject the user list contains all the connected clients to the lobby and if the number of the connected users is by hundreds or thousands i think if i create a loop for updating the own user users list statues it would not be good idea,,,
so what is the best way to let the user build his own users list and get the statues of each user in his list from the application online users sharedObject witch connected to the lobby app
I'd like to create a combobox which will get users from an arrayList & another field for creating a new user. for example when i open the combobox i'd like to see the rows :
Create new user User A User B
where the users come form an arrayList and the "create new user" option is always there.
How can I do it?P.S I don't wan't to add "create new user" obj to the arryList - so this is not a desired solution.
I'm building a chat using Flex. The problem is how to do that new user get the list off all users online and added to the lists of all users. I try to put this information in DataGrid through dataProvider "callerns"[code]...Exchange user names and peer IDs between all connected users
I am working on the project where everything is based on the distance from the center of the stage. First I made this fla where flash outputs the x and y distance from the center. First problem is that I want to output distance only in positive numbers.
i'd like to know if its possible to save information obtained from users to files if the user is accessing the flash file from a cd. I would also like to know how it works if possible. And can the flash file be in .exe instead of .swf?
I am posting my code that attaches the movieclips on stage
[Code]...
i was hoping that when the newMc expands, all other mc would keep the same distance between each other as at initialisation. I not able to figure how to do it. maybe even an earlier post or llink where similar query was explained.
On the stage:Textfield called "inputTXT".And a button called "Go". All I am trying to accomplish here is to have the input characters validated to be ONLY numbers and max 5. However, I don't want to use:"inputTXT.restrict = "0123456789".
Instead I would like to check if the characters entered after pressing the "go" btn, are within the defined parameters above (numbers and max5). If yes, then I need to pass a URL, if not then I need to display an error message.
I know about Local connection class connecting two swfs in the same web page.But kindly let me know if there is any way to connect to two swfs residing in different web pages.
I have an alchemy compiled swc which contains methods to perform certain key algorithms. These methods should only return values only if user is authorized(bought license from online service) for security purpose. So I am planning to add another SWC on top of this, which have all the licensing code stuff. But when I import the Alchemy generated swc inside my custom swc, all the methods of alchemy are exposed.

Is there a way that I can find out the screen resolution of a users screen? I want to add scroll bars for users with a resolution lower than 1440X900 and if u have 1440x900 or greater it wont show the scroll bars.
ok how do you find out if the user is scrolling the mouse?? like you can tell where the user points there mouse, with a onRelease, is there like an on scroll also i am gonna start upa flash web site bussines thingy, any tips on how much i should charge for a web site? i might cahrge between 50dollars to 200 dollars depending on how tricky it is, is this good or bad?
I am displaying a word in a text box that was submitted by a user. What I need to figure out is, if anywhere in that text the letters "com" appear in order i need to change the font color of just those letter. Is it possible to search a word to determine if the letters appear consecutively and then apply the styling to just those letters?
I've two text boxes to enter two string. How can i find the similar characters that the user entered
For example
First text box : jain second text box : claton
Two "a" appers on the two strings. That is in the first entry's second position and the second entry's third position. How to find out any similar characters inside the entry
How can I find the path to the user's temp folder (e.g. C:UserslisnilAppDataLocalTemp) from Flash/AS3? It needs to work on any version of Windows, at least XP, Vista and 7.
how can I get Flash to find the difference (in days) between two dates that the user enters? For example if I have six input text boxes and I call them:
day1 month1 year1 day2 month2 year2
respectively, how can I get a dynamic text box called, say, "output" to find the difference between two dates that the user enters into the six text boxes, e.g.
day1 - The user enters 03 month1 - The user enters 09 year 1 - The user enters 2006 day2 - The user enters 25 month2 - The user enters 12 year2 - The user enters 2006
How do I get Flash to find the difference between today and Christmas?
