Is it possible to call a function into another function or stop a function from executing because criteria from another function where not met?

You first need to call the parent function.

Language: PHP
function one () {
    function two () {
     echo "2";
   }
 
   echo "1";
 }
 
two(); //Fatal error: Call to undefined function 2() 
 
one(); // 1
two(); // 2
 ?>

2nd part.. mmmm what do you want to do?

I want to create a validation function to use on multiple insert/update functions instead of adding validation into each of them separately

Why not just call a single validation function when required?

I couldn't get it to work like that this AM, however if I added the code before my queries it worked. Will mess around and get it sorted
