function problem

[Martoni]

Can anyone see what's wrong with this function? Running the query directly in MySQL produces correct results (ie a value for free and total_entitleme nt).

function Count_licenses( $sID)
{
global $adb,$bgcl,$bgc d, $free;
$query = "SELECT * FROM software_licens es WHERE (sID = '$sID')";
$sth = $adb->prepare($query );
if($sth)
{
$res = $sth->execute();
$numRows = $sth->rows();
$record = $sth->fetchrow_hash( );
$free = $record[free];
if($free = "No" || $free = ""){
$total_entitlem ent=0;
for ($i=0;$i<$numRo ws;$i++) {
$record = $sth->fetchrow_hash( );
$total_entitlem ent+= $record[entitlement];
}
}else {
$total_entitlem ent = "Not applicable";
}
$sth->finish();
} else
{
PRINT "Could not prepare query: ".$sth->errstr."<BR>\n ";
}
return $total_entitlem ent;
}

Re: function problem

It never returns a value of total_entitleme nt other than 0.

Uh Oh!
assignment, not comparison ... what do you expect the contents of $free
to be after this statement?

Uh Oh!
read a second row and disregard the first?
It doesn't seem a good idea, especially when the second row is empty and
you don't test it.
