我看不出如何在下面的过滤器函数中正确使用PHP if语句。如果$_POST 输入有值，但如果任何输入为空，则会出现致命错误。所以我想告诉它不要运行任何代码，因为这些输入中的任何一个都是空的。
add_action( \'gform_after_update_entry_7\', \'add_length_on_update\', 10, 2 );
function add_length_on_update( $form, $entry_id ) {
// get input from form
$date = $_POST["input_3"];
$start = $_POST["input_27"];
$end = $_POST["input_28"];
// convert date and time arrays into datetime formats
$startdate = DateTime::createFromFormat(\'m/d/Y@h:i a\', $date . "@". $start[0].":".$start[1]." ".$start[2]);
$enddate = DateTime::createFromFormat(\'m/d/Y@h:i a\', $date . "@". $end[0].":".$end[1]." ".$end[2]);
//convert datetimes into seconds to compare
$starttime = strtotime($startdate->format(\'Y-m-d H:i:s\'));
$endtime = strtotime($enddate->format(\'Y-m-d H:i:s\'));
// check to see if the times span overnight
if($starttime > $endtime) {
$endtime = strtotime($enddate->format(\'Y-m-d H:i:s\') . " +1 day");
}
// perform calculation
$diff = floor(($endtime - $starttime)/30);
GFAPI::update_entry_field( $entry_id, 32, $diff );
}

Here you go..
add_action( \'gform_after_update_entry_7\', \'add_length_on_update\', 10, 2 );
function add_length_on_update( $form, $entry_id ) {
if( !empty($_POST["input_3"]) && !empty($_POST["input_27"]) && !empty($_POST["input_28"]) ){
// get input from form
$date = $_POST["input_3"];
$start = $_POST["input_27"];
$end = $_POST["input_28"];
// convert date and time arrays into datetime formats
$startdate = DateTime::createFromFormat(\'m/d/Y@h:i a\', $date . "@". $start[0].":".$start[1]." ".$start[2]);
$enddate = DateTime::createFromFormat(\'m/d/Y@h:i a\', $date . "@". $end[0].":".$end[1]." ".$end[2]);
//convert datetimes into seconds to compare
$starttime = strtotime($startdate->format(\'Y-m-d H:i:s\'));
$endtime = strtotime($enddate->format(\'Y-m-d H:i:s\'));
// check to see if the times span overnight
if($starttime > $endtime) {
$endtime = strtotime($enddate->format(\'Y-m-d H:i:s\') . " +1 day");
}
// perform calculation
$diff = floor(($endtime - $starttime)/30);
GFAPI::update_entry_field( $entry_id, 32, $diff );
}
}
