how to submit and post a search field using pl sql

问题

i would like my button to be embedded within this cursor. so when a user inputs data onto the 'search_field' and clicks the button 'Unsuspend', the Process SCRIPT should run and post 3 different information (Student_no, Suspend_account, and Student_name ) onto my next page.

is there any java script i have to include if so please help. if not what can i do to run the process script.

--Process SCRIPT--

It looks like your HTML isn't complete... you should have something like

 <form action="my-next-page.html">
  Student ID:
  <input type="text" name="student_id" >
  <input type="submit" value="Submit">
 </form> 

But here you're only generating the beginning. You probably need to add a little more, like the "form" thing above until the closing tag:

htp.BOLD ('Enter the Student ID you wish to unsuspend for the Aspire account');
htp.br;
htp.br;
htp.BOLD ('- PLEASE NOTE Student ID''s that are submitted will be pending unsuspension until the next working day');
htp.p ('<form action="my-next-page.html">');
htp.p (' Student ID: ');
htp.p ('<input type="text" name="student_id" >');
htp.br
htp.p ('<input type="submit" value="Submit">');
htp.p ('</form>');

And then resulting post should be processed in my-next-page.html. But you really should work on an MCVE, because here it's very unclear what you're asking.
