使用三元运算符

Question

I am working on a PHP project and got an error:

CODE:

 echo'<table>  
<td> ' .(   ($approve == 1 AND $decline == 0 )? "<span style='color: green'>  approved</span>" 
      : ($approve == 0 AND $decline == 0 )? "<span style='color: orange'>  
      Pending </span>" : "<span style='color: red'>  Declined </span>"
       ).   ' </td> </table>';

Is the above format for using ternary operator right? because I can not get the right value. please tell me what is the error?
edit:
the error is i can't get approved instead iam getting pending and declined.

Answer 1

Your error in using "()"

$approve = 1;
$decline = 0;

$res = ($approve == 1 AND $decline == 0)
    ? "<span style='color: green'>  Approved</span>"
    : (
    ($approve == 0 AND $decline == 0)
        ? "<span style='color: orange'>  Pending </span>"
        : "<span style='color: red'>  Declined </span>"
    );

echo $res;

The third operand of the first condition must be in parentheses.

For your code using parentheses:

echo '<td>'
. (($approve == 1 AND $decline == 0)
    ? "<span style='color: green'>  Approved</span>"
    : (
    ($approve == 0 AND $decline == 0)
        ? "<span style='color: orange'>  Pending </span>"
        : "<span style='color: red'>  Declined </span>"
    ))
. '</td>';
