PHP语法错误。 添加Wordpress函数时意外$ EOF

Question

I'm getting syntax error, unexpected $EOF when adding this function to a Wordpress functions file. See anything?

function get_saturation($atts) {
 <?php    $sws = exec("awk -F\",\" '{if(NR==2) printf(\"\%.1f \
\",($10/8.4)*100 )}'  https://website.org/data/lastrec.csv", $retval);
      echo   $sws . " percent saturation<br>";    ?>
}
add_shortcode('saturation', 'get_saturation');

Answer 1

You have opening and closing PHP tags in the wrong places (within the function, i.e. before $sws)

 function get_saturation($atts) {
  $sws = exec("awk -F\",\" '{if(NR==2) printf(\"\%.1f \
\",($10/8.4)*100 )}'  https://website.org/data/lastrec.csv", $retval);
  echo   $sws . " percent saturation<br>"; 
}
add_shortcode('saturation', 'get_saturation');
