Having Some Troubles With RemoveField

Apex · August 2009

So the removeField command is supposed to remove a single field out of a tab seperated list, correct? I'm having some weird instances of it leaving some text behind.

For instance...

$test = "g1\tg2";
echo(removefield($test,1));
 g1	1

So it removes g2... but what's with that extra TAB and 1 at the end?

Any assistance would be much appreciated.

EDIT: Looks like removeWord does the same thing... Odd.

echo(removeword($test,1));
 g1	1

I should also note that removing the first field rather than the second seems to work fine.

echo(removefield($test,0));
 g2

Krash and nil both supplied me with a re-writes of this function that can be found at the following URLs.

function removeField(%list,%index) {
    %count = getFieldCount(%list);
    if (%index == 0) %result = getFields(%list,1,%count);
    else if (%index == %count-1) %result = getFields(%list,0,%index-1);
    else if (%index >= %count) %result = %list;
    else %result = getFields(%list,0,%index-1) TAB getFields(%list,%index+1,%count);
    return %result;
}

function removeToken(%string, %token, %index)
{
	%str = "";
	for (%i = 0; %i < %index && %string !$= ""; %i++)
	{
		%string = nextToken(%string, "temp", %token);
		if (%i == 0)
			%str = %temp;
		else
			%str = %str @ %token @ %temp;
	}

	%string = nextToken(%string, "temp", %token);
	if (%string !$= "")
		%str = %str @ (%index == 0 ? "" : %token) @ %string;
	
	return %str;
}

Preserved for posterity.
