php - Insert "Selected Users" into another table -


okay having kinds of problems trying figure way script this.

what want have list of people displayed mysql database. once list generated have checkbox next each person.

now here tricky part (at least me), each person checked enter 1 column in table in database. call "rsvp" life of me cannot figure out.

basically need enter user id's checkbox ex these id's checked "1,4,5,6,8". need enter database table "rsvp" , able go , modify same entry checkboxes selected.

i think way on thinking , simple solution.

you should

1) result set database

2) array of selected members

3) iterate of actual dataset , keep generating check boxes, if id matches selected id, generate check box checked.

4) on submitting form, clear old entries , re-insert whatsoever has been selected.

  <form>   <?php   $resultset = getalltheusers here ////   $arrayofselectedusers= getalreadyselectedusers();   //      keep array "id"=>'user name'    while(result not empty){     if(array_key_exists('bar', $foo))         echo "<checkbox value=$result['userid'] checked='checked' name='rsvp' />";    else       echo "<checkbox value=$result['userid']  name='rsvp' />";   }   ?>   <input type='submit' />   </form>

this should give idea. once form submitted, values, delete existing entries database , re-insert ever has been selected again.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
