Simple Online Voting system php--publish poll page

The publishing page is only available when the user is logged in, so check that you are logged in and then allow the poll to be issued.

 
  
  
   
  
   
Note: Once published will not be modified!
 
  

The information entered by the user is posted to the background in post format.

 = $min && $vname = "") {for ($i =1; $i < $itemcount; $i + +) {$j = $i +1; $item = $item. '                * '. @$_post[$j];            $num = $num. ' *0 ';            } $sql 3= "Select uid from users WHERE username= ' $ouser '";            $getVid =mysql_query ($sql 3);            $row =mysql_fetch_row ($getVid);            $uid = $row [0]; $sql = "INSERT into vote (vname,starttime,uid,vintro,open,more,max,min) value (' $vname ', ' $starttime ', ' $uid ', ' $vintro ')            , ' $open ', ' $more ', ' $max ', ' $min ');            mysql_query ($sql);            $sql 2= "Select vid from vote WHERE vname= ' $vname '";            $getVid =mysql_query ($sql 2);            $row =mysql_fetch_row ($getVid);            $vid = $row [0];            $sql 4= "INSERT into Votetitle (vid,itemcount,item,num) value (' $vid ', ' $itemcount ', ' $item ', ' $num ')";            mysql_query ($sql 4);        echo "";        } else{echo "";    }}else{echo ""; }}?>

1. Check if login

    $ouser =@$_get[' user '];    if ($ouser! = ") {

2. Get the current time

        $time =time ();        $starttime =date ("y-m-d", $time);

3. Form the option information and voting statistics that can be saved in the database

   $item =@$_post[1];        $num =0;        if ($max >= $min && $vname! = "") {for            ($i =1; $i < $itemcount; $i + +) {                $j = $i +1;                $item = $item. ' * '. @$_post[$j];                $num = $num. ' *0 ';            }

(1) Option information and poll statistics are composed of a string by separating the option information with "*"

Example: "Option one * option two * option three"

(2) The default initial voting statistics, the items are all 0.

Example: "0*0*0"

(3) This loop statement is not necessary, in PHP provides a special method of integrating and decomposing arrays into strings (explode and implode), but in the completion of this part of the code I do not know the application of this method, GU self completed this function.

The above describes the simple online voting system php--the release of the voting page, including the content, I hope that the PHP tutorial interested in a friend helpful.
