Insert data into postgres Database script needed

Hi all,

I need some simple code that does just the following:

Hope the below describes what I need:

<a href="">Save to Database Table</a> //A link here to activate the saving

var $value1='200';  
var $value2='blablabla';

etc...

...then something like:

pg_query("INSERT INTO myTable VALUES ('$value1','$value2','$fvalue3','$value4')");

echo 'Data has been saved';

//the end

Can anyone help put a script together to do the above please?

Thanks
