This program is always unable to submit data in the generated interface. it always prompts that the information with the asterisk is not complete, but I have already completed this post and edited by jackbill43 at 15:09:41.

If (! $ Class_name |! $ Class_number |! $ Roster_status) {echo "script" alert (the 'form is not complete and an asterisk is required! '); History. back ();"; Exit ;}
Where is $ roster_status defined and assigned? The code you posted does not include any related fields in the form on the page. This will certainly trigger this verification.
If (! $ Class_name |! $ Class_number |! $ Roster_status) {echo "script" alert (the 'form is not complete and an asterisk is required! '); History. back ();"; Exit ;}

How did you change it?

How did you change it to the previously defined class_status?
Var_dump ($ _ POST); for details
1. $ _ POST is a variable that stores data submitted from the form using the post method. var_dump is used to print the internal structure of the variable and check whether the class_status is submitted by the form, if yes, what is the value?
2.
Select classroom status Value = "0"> idle Value = "1"> course available
This place. The value of the option "classroom status" and "idle" is both 0, which is unreasonable. If you select these two states, the class_status submitted by the form is 0 ,! When the logic non-operator calculates 0, the result is the same as true, so an error is triggered.
