About simplifying code. Seeking the guidance of the Great God
It's half a month to mingle with CSDN. A lot of harvest, want to settle here.
Like the atmosphere here, like the great God here.

if (empty ($grouptypeid)) {
ShowMsg (' Please specify your own exam! ', '-1 ');
        Exit ();
}if (Empty ($content)) {
    ShowMsg (' content cannot be empty! ', '-1 ');
Exit ();
}if (Empty ($teachername)) {
    ShowMsg (' Please choose teacher! ', '-1 ');
Exit ();
}if (Empty ($years)) {
    ShowMsg (' Please select the date ', '-1 ');
Exit ();
}if (Empty ($isupdate)) {
    ShowMsg (' Please select Update Date ', '-1 ');
Exit ();
}

How is this easy to write?

------Solution--------------------
The simplification of this code should be done when the relevant variable is assigned a value
You're doing the validation of the incoming data, apparently tangible as
$grouptypeid = $_post[' Grouptypeid ');
Such a code snippet

So there are

$dict = Array (
  ' Grouptypeid ' = ' Please specify your own exam! ',
  ' content ' = ' contents cannot be empty! ',
  ' TeacherName ' = ' Please choose a teacher! ',
  ' Years ' = ' Please select the date ',
  ' Isupdate ' = ' Please select the update Date ',
);
foreach ($_post as $k = = $v) {
  if (empty ($v)) {
    ShowMsg ($dict [$k], '-1 ');
    Exit
  }
  $ $k = $v;
}
