php - redirecting a survey user to last page that he/she was on -


i have been working on survey , done, there's 1 requirement has eaten me up.

a user can take survey, , there 6 different sets of questions , each set of questions in question group 1-6. when user question group 1-4 , logs out, he/she should log in , redirected question group 5. far code working , redirecting first 3 pages (questions1.php, people.php , environment.php), refusing rest.

i think problem if elseif statement. achieve desired result appreciated. cheers!

here code

if ($row['userid']==$user){ while($row = mysql_fetch_assoc($result_set)){ if($row['question_group_id']==1 && $row['choosen']==1){  header("location:people.php");         } elseif($row['question_group_id']==2 && $row['choosen']==1){  header("location:environment.php");      } elseif($row['question_group_id']==3 && $row['choosen']==1){  header("location:widerorganization.php");     } elseif($row['question_group_id']==4 && $row['choosen']==1){  header("location:procurement.php");    } elseif($row['question_group_id']==5 && $row['choosen']==1){  header("location: communication.php");     } elseif($row['question_group_id']==6 && $row['choosen']==1){  header("location: notificationpage.php");      }}}  else {  header("location:questions1.php");      }

it's matter of rendering clean codes.

i reformatted code. here's code before:

if ($row['userid']==$user) {     while($row = mysql_fetch_assoc($result_set))     {         if ($row['question_group_id']==1 && $row['choosen']==1)         {             header("location:people.php");         }         else if($row['question_group_id']==2 && $row['choosen']==1)         {             header("location:environment.php");          }         else if ($row['question_group_id']==3 && $row['choosen']==1)         {             header("location:widerorganization.php");         }         else if ($row['question_group_id']==4 && $row['choosen']==1)         {             header("location:procurement.php");          }         else if ($row['question_group_id']==5 && $row['choosen']==1)         {             header("location: communication.php");         }         else if ($row['question_group_id']==6 && $row['choosen']==1)         {             header("location: notificationpage.php");          }      } } else {     header("location:questions1.php");  }

solution: since every condition has predictable pattern, why don't put pages associative array instead of creating tedious if conditions? anyhow, proposed adjustment code.

<?php  $locations = array(     // question group id => landing page     1 => 'people.php',     2 => 'environment.php',     3 => 'wideorganization.php',     4 => 'procurement.php',     5 => 'communication.php',     6 => 'notificationpage.php' );  if ($row['userid']==$user) {     while($row = mysql_fetch_assoc($result_set))     {         // here's question group id         $questiongroupid = $row['question_group_id'];          // determine here         if (isset($locations[$questiongroupid]) && $row['choosen'] == 1)         {             // defined associative array above             header(sprintf("location:%s", $locations[$questiongroupid]));             exit();         }     } } else {     header("location:questions1.php");  }

now it's easier debug. please try code ;)
