Code:
$abc = 'a';
echo '狀態: ';
echo form_radio('Status', 'a',if($abc == 'a')echo TRUE;);Parse error: syntax error, unexpected T_IF in
WHY?

You can't add a control structure as a parameter. and using echo makes it even worse as it outputs the value.

right!
I think you could write it like this:
Code:
echo form_radio('Status','a',($abc=='a')?TRUE:FALSE);form_radio problem - El Forum - 10-02-2008

($abc == 'a') is already a boolean expression.
Code:
echo form_radio('Status','a', ($abc=='a') );form_radio problem - El Forum - 10-02-2008

True, but I wanted to exemplify the use of the ternary operator instead of if control structure
