Get Total Number of Likes from Facebook Page

admin — Sun, 10 Apr 2011 02:04:22 +0000

You can always use a custom Facebook Like Button that displayes the number of likes from the FB Developer’s page. But if you’re looking to control the way that number is displayed (maybe a large font or in a funky graphic), you can access this information using the Facebook Graph API URL. It will return all the Page information in a JSON data format like so using Pepsi’s Page: http://graph.facebook.com/56381779049 The number 56381779049 could be the Page or User ID you’re referring to on Facebook. Notice how it will return a array of information. You will find that total number on the line labeled “likes”.

How to check for number values only and block or convert letter strings to integers. Question: How to validate number values to and block all letters and symbol in a form. Answer: You can check the value or convert the value to an integer (number). 1) Check a value using is_int() to finds whether the given variable is an integer 2) Note: To test if a variable is a number or a numeric string (such as form input, which is always a string), you must use is_numeric(). 3) Convert the value to an integer (number) using settype.



settype($foo, "integer"); // $foo is now 5 (integer)
settype($bar, "string"); // $bar is now "1" (string)
?>

Here is how to use actionscript to format a number in Flash with commas per thousands.


my_number = "12587654325";

// array in sections of 3 to separate with commas
trace(my_number);
var dollar_array:Array = new Array();
var start:Number;
var end:Number = my_number.length;
trace(my_number.length);
while (end > 0) {
trace(end);
start = Math.max(end - 3, 0);
dollar_array.unshift(my_number.slice(start, end));
end = start;
}

// assign a comma delimited value from dollar_array
my_number = dollar_array.join(",");
trace(my_number);

Using javascript regular expressions to stop users from entering non-aphanumeric characters or white spaces


Say you want to stop users from entering non-aphanumeric characters or white   spaces.

Using regular expressions would be the easiest method:

Here is my javascript code:

 
For numbers only use /^+$/

For mixed text and numbers, with spaces /^+$/

Here are more useful regular expressions:

 any letter
d any number; same as 
D any NOT number; same as 
w any alphanumeric character; same as 
W any NON-alphanumeric character; same as 
s any whitespace (tab, space, newline, etc...)
S any NON-whitespace
n newline
t tab

Actionscript Converting Negitive to Positive Numbers
admin — Sat, 11 Dec 2004 00:22:11 +0000
Needed to know the simples way to convert a number from positive to negative or negative to positive in actionscripts. Here it is.


This is a revise to the flash actionscript tutorial on converting negitive numbers to positive numbers.

Now use Abs() function in flash actionscript
Math.abs()
The flash Math.abs() method is used to return the absolute value of x. This basically means it returns the distance between 0 and x in flash actionscript.

Although -5 is a negative number, it's absolute value is the same as 5. This is because -5 has a distance of 5 from x just as 5 has a distance of 5 from x.

Example:
Math.abs(-10); // Returns 10
Math.abs(10); // Returns 10
Old Tutorial on Converting Negatives to Positive and Positive to Negative numbers
I needed to know the simples way to convert a number from                        positive to negative or negative to positive in actionscripts.                        Here it is:


// convert 100 to negative -100
n = 100;
n = - n;
trace(n);// will = -100
// convert -55 to positive 50
n = -50;
n = - n;
trace(n);// will = 50



This is how it work. Zero minus a positive number = a negative                        number. And Zero minus a negative number = a positive number.
