Question

I need to receive a variable with multiple values from php in as3,

the variable is

$errors = "1, 4, 5" 

but it changes the values.
I need to take the values and , “read” them and depending on what values there are I’m supposed highlight corresponding fields, like errors gives me 1

er_1.gotoAndStop(2);
er_1.visible = true;

this would be easy with a simple if{} if I was receiving 1 value but I don’t know how to check for multiple values, please help?

Answer 1

If your values are separated by commas (or any common string), you can split a string along that comma to get an array of strings.

Example:

var fromPhp:String = "1, 4, 5";

// Note that it is splitting across the string ", " since 
// you have comma and a space that separates each number
var errors:Array = fromPhp.split(", ");

trace(errors.length) // prints 3, as you had 3 values
trace(errors[0]); // prints 1
trace(errors[1]); // prints 4
trace(errors[2]); // prints 5

Note that all the values inside error are still strings, so you may need to parse them back into ints.
