Function creation

Sharif

I need some help creating a function called missing_field(). I want this function to do the same thing this would do:

if(!$username)
{
echo $regError['username'];
}
elseif(!$name)
{
echo $regError['name'];
}

What I am trying to do is, if the variables that I specify in the function isn't there, I want to display a custom error for each missing variable ($regError holds a bunch of error messages). How can I do this?

First off, it starts off as this right?:

function missing_field()
{
WHAT GOES HERE???
}

Sure,


function missing_field($field='') {
   if(!$field) {
      echo $regError[$field];
   }
}

I already though about that as a solution but the complication in this code is this, I can't specify which fields I want to use the function on.

I only want this function to be able to determine CERTAIN variables that are missing and display error messages according to the specific variable that is missing.

Ok so you want to check agaist $regError, and anything that is missing for globals that is in that array, results in an error?

such as $regError['boo'] is set, and $boo is not, that gives an error?

You will have to do a for each varible in $regError while, and check if that varible exists.

If you want me to make you the code, replay once again(just I am at work)
