All,
I have a form on which the user is supposed to select a variable type
(boolean, integer, real, date/time, text) from a select box and enter the
default value for this selected variable type in a text box. I'm trying to
validate that the default value entered matches the variable type selected
i.e. user selects boolean so valid defaults could only be 0, 1, true, false
and anything else would generate an error, or the user selects integer and
enters 1.7 for the default would also throw a flag. I know that all of the
form values submitted from the web page are strings but is there a way to
test/convert the strings against the other variable types.
I'm sure that I'm not explaining this very well, but for example, if I use
the following code I will always get an error displayed even if the user
enters a valid value such as 3 in the default field because the form values
are always submitted as strings.
if ( ($GLOBALS['PageOptions']['Type'] == 'Integer') and (!
is_int($GLOBALS['PageOptions']['Default']) ) )
{
// display an error
}
If I use (int) on the form default value then that won't work either because
if the default field value entered was not an integer but text such as
'snafu' then the value is always converted to an integer regardless.
if ( ($GLOBALS['PageOptions']['Type'] == 'Integer') and (! is_int((int)
$GLOBALS['PageOptions']['Default']) ) )
{
// display an error
}
Thanks in advance,
Dave Merritt
