T/F function

[Anon]

I am trying to create a function that will evaluate a number of results from an array and depending on whether the value held is "T" or "F" then set that array value to "checked" or "" to control my checkboxes. I am querying a database and need to graphically represent the T or F's or NULL's for that matter as checkboxes. What I have so far is

function checkbox($boxstatus) {
global $value;

IF ($boxstatus =="T"){
$value="checked";
}
ELSE $value="";
}

//$boxstatus will be an array value such as
//$myrow[colname].

I would really like to just modify the array value and use that to define my checkbox behavior, but I can't quite figure out how to get a function to work with a constantly changing variable name. If anyone has already tackled this problem and has some sample code I would greatly appreciate it.

Am I right in figuring that you want to take the 'T's and 'F's and such in the array and replace them with "checked" and ""?

Even if that's not the case, then using variable references sounds like the solution you're looking for. If it is the case you'd use them like this:

--reference here--v
function checkbox(&$boxstatus){
if($boxstatus=='T')
{ $boxstatus='checked';
}else
{ $boxstatus='';
}

checkbox($myrow['colname']); will then update $myrow['colname'] to be 'checked' or ''.

With the reference marker there, the variable passed to checkbox() will have its value tied to that of $boxstatus inside the function, so that changing the latter has the same effect as changing the former.
