Help with poll system

Flyier

Hi.

I want to write a poll system and i have problems with the page, where people can add question and answers. The things is that i want to make the answers input text areas dynamic, i mean the number of the answers to be controlled by the user, like the poll in phpBB for example with button "Add answer" where the page is reloaded with one more place for answer.

<?php
if(isset($_GET['count'])){
      $count = $_GET['count'];
      $count = $count+1;
} else{
      $count = 1;
}

?>

<body>
<table cellpadding="0" cellspacing="0" border="0">
<?php
for($i=0; $i<$count; $i++) {
      echo "<tr>";
            echo "<td>";
                  echo "<input type=\"text\" value=\"\" size=\"28\"/>";
            echo "</td>";
      echo "</tr>";
}
?>
      <tr>
            <td><a href="<?php echo "".$_SERVER['PHP_SELF']."?count=$count"."" ?>">Add</a></td>
      </tr>
</table>
</body>
</html>

How can i reaplace the "Add" link with button to reload the page with one more text area and still to save the values of the other answers ?

Thanks in advance.

Not the most elegant solution, but it will work. You will use the POST vars to keep track rather then the GET vars, that way you can keep the value of each field with out having to muck with the query string in a link.

<?
//start form
echo "<form name=\"form1\" action=\"\" method=\"post\">\n";

//check if the add field button was clicked.
if(isset($_POST[addField])){
   $addField = count($_POST[value]);
   $addField++;
   $value = $_POST[value];
}



//this is a default page load, no user input.
if(!isset($addField)){
   echo "<input name=\"value[]\" value=\"\"> <input type=\"Submit\" name=\"addField\" value=\"Add\">\n";

}else{
   //the user has selected to add a field.

   //loop though our addFields and put in form input for each.
   for($i = 0; $i < $addField; $i++){
      //see if this is the last input, if it is add the add button back to it..
      if($i+1 == $addField){
         echo "<input name=\"value[]\" value=\"$value[$i]\"><input type=\"Submit\" name=\"addField\" value=\"Add\">\n";
      }else{
         echo "<input name=\"value[]\" value=\"$value[$i]\"><br>\n";         

      }
   }
}


?>

Let me know if this doesn't make sense, but it's straightforward and should be easy to edit your script to work like this.

I realised almost the same, but I want a button to send the information to the proccess page :

<?php
//Params
//GET Count
if(isset($_GET['count'])){
      $count = $_GET['count'];
      $count = $count+1;
} else{
      $count = 1;
}
//SET CURRENT ACTION
if(!isset($_GET['action'])){
      $action = "list";
}      else {
      $action = $_GET['action'];
}

if($action == "add"){
      for($i=0; $i<$count; $i++) {
            $s_value[$i] = ($_POST['s_value'.$i]);
            $i_value[$i] = $s_value[$i];
      }
}
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Poll System</title>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1251">

<body>
<form method="POST" action="<?php echo "".$_SERVER['PHP_SELF']."?action=add&count=$count"?>" name="pubform" enctype="multipart/form-data">
<table cellpadding="0" cellspacing="0" border="0">
<?php
for($i=0; $i<$count; $i++) {
?>
      <tr>
            <td><input type="text" name="<?php echo "s_value".$i.""; ?>" id="<?php echo "s_value".$i.""; ?>" value="<?php echo "".$i_value[$i]."" ?>" size="28"/></td>
      </tr>
<?php
}
?>
      <tr>
            <td><input type="submit" name="submit" id="submit" value="Add" size="15"/></td>
      </tr>
</table>
</form>
</body>
</html>

Like a submit button to process the form?

<?
//start form
echo "<form name=\"form1\" action=\"\" method=\"post\">\n";

//check if the add field button was clicked.
if(isset($_POST[addField])){
   $addField = count($_POST[value]);
   $addField++;
   $value = $_POST[value];
}

#ADDED
if(isset($_POST[procForm])){
   //code to process form.
   echo "Going to process the form<br>\n";
}



//this is a default page load, no user input.
if(!isset($addField)){
   echo "<input name=\"value[]\" value=\"\"> <input type=\"Submit\" name=\"addField\" value=\"Add\">\n";
   #ADDED
   echo "<input type=\"Submit\" name=\"procForm\" value=\"Submit\">\n";

}else{
   //the user has selected to add a field.

   //loop though our addFields and put in form input for each.
   for($i = 0; $i < $addField; $i++){
      //see if this is the last input, if it is add the add button back to it..
      if($i+1 == $addField){
         echo "<input name=\"value[]\" value=\"$value[$i]\"><input type=\"Submit\" name=\"addField\" value=\"Add\">\n";
         #ADDED
         echo "<input type=\"Submit\" name=\"procForm\" value=\"Submit\">\n";
      }else{
         echo "<input name=\"value[]\" value=\"$value[$i]\"><br>\n";         

      }
   }
}


?>
