Calling a function twice

[Jezza22]

I have a php function that gets the next available document number, from a MYSQL database, which works great. I have a page, that combined with php/javascript and using an Ajax method, updates the database and increments the document number.

 

The problem I have is refreshing the page to show incremented document number.

 

Is it possible call the function again and it perform function again, retrieving the new values from the database, without submitting the page?

 

I have tried lots of things with no success.

 

I'm fairly new so please bear with me

 

Here's the function: -

 

function DocumentNext()
{
	$query = "SELECT * FROM counts_file;";
	$result = mysql_query($query);			
	$nextDoc=mysql_result($result,$j,'Document');


	echo $nextDoc;

}

 

I can post the remainder of the code if necessary that containts the javascript let me know?

You could return that value in the response to your ajax call and using javascript update the place on the page that shows this number.
