calling functions

nuttynibbles

hi, i got 2 functions i need to work with..

validate_empty_fields($fields="")
{

....
}

checkQty($temp)
{
if(validate_empty_fields($temp)
return true;
else
return false;

}

but i keep getting the error (highlighted in red) saying "Call to undefined function" why??😕

I think you are missing an important keyword:

function validate_empty_fields($fields = "")
{
    // ...
}

function checkQty($temp)
{
    // ...
}

Incidentally, you might want to be consistent in naming your functions. Choose to separate words by underscores, or to use camel case. Avoiding naming some functions with one style and other functions with another.

do i need to define functions??

coz the function i did is in a class.. so the whole thing shu look like this:

class validate{
validate_empty_fields($fields="")
{

....
}

checkQty($temp)
{
if(validate_empty_fields($temp)
return true;
else
return false;

}
}

If you do not define them, you cannot use them. You cannot use that which does not exist.

Same difference. You may wish to read the PHP Manual concerning classes.

You can start by reading the PHP Manual on functions.
