Form repeats values
- by Tunji Gbadamosi
I have a dynamically generated form to accept guest details and store the results into the a session array. However, when I retrieve the details, I keep finding that the last two guest details are always the same even though different inputs were given.
Here's my form for getting the values (guests.php):
<?php
session_start();
require_once 'FormDB.php';
include 'connect.php';
include 'guests_.php';
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Enter guest details</title>
<script language="JavaScript" type="text/javascript" src="validation_functions.js"></script>
</head>
<body>
<?php
if($_SESSION['logged_in']){
//print '<script type="text/javascript">';
//print 'alert("You have successfully logged in '. $_SESSION['volunteer']['first_name'].'")';
//print '</script>';
$first_name="first_name";
$surname="surname";
$sex="sex";
$age = "age";
echo $error;
//echo '<form name="choose" action="tables.php" method="post" onsubmit="return validate_guests(this);">';
echo '<form name="choose" action="guests.php" method="post" onsubmit="return validate_guests(this);">';
echo '<input type="hidden" name="hidden_value" value="'.$_SESSION['no_guests'].'" />';
if($_SESSION['no_guests'] >= 1){
echo '<table border="1">';
echo '<th>First Name</th>';
echo '<th>Surname</th>';
echo '<th>Day of Birth</th>';
echo '<th>Month of Birth</th>';
echo '<th>Year of Birth</th>';
echo '<th>Sex</th>';
//echo '<div id="volunteer">';
echo '<tr>';
echo '<td>';
echo $_SESSION['volunteer']['first_name'];
echo '</td>';
echo '<td>';
echo $_SESSION['volunteer']['surname'];
echo '</td>';
echo '<td>';
echo $_SESSION['volunteer']['dob_day'];
echo '</td>';
echo '<td>';
echo $_SESSION['volunteer']['dob_month'];
echo '</td>';
echo '<td>';
echo $_SESSION['volunteer']['dob_year'];
echo '</td>';
echo '<td>';
echo $_SESSION['volunteer']['sex'];
echo '</td>';
echo '</tr>';
//echo '</div>';
for($i=0;$i<$_SESSION['no_guests'];$i++){
//$guest = "guest_".$i;
//echo '<div class="'.$guest.'">';
echo '<tr>';
echo '<td>';
echo '<input type="text" name="guest['.$i.']['.$first_name.']" id="fn'.$i.'">';
echo '</td>';
echo '<td>';
echo '<input type="text" name="guest['.$i.']['.$surname.']" id="surname'.$i.'">';
echo '</td>';
echo '<td>';
echo '<select name="guest['.$i.'][dob_day]" id="dob_day'.$i.'">';
for($j=1;$j<32;$j++){
echo"<option value='$j'>$j</option>";
}
echo '</select>';
echo '</td>';
echo '<td>';
echo '<select name="guest['.$i.'][dob_month] id="dob_month'.$i.'">';
for($j=0;$j<sizeof($month);$j++){
$value = ($j + 1);
echo"<option value='$value'>$month[$j]</option>";
}
echo '</select>';
echo '</td>';
echo '<td>';
echo '<select name="guest['.$i.'][dob_year] id="dob_year'.$i.'">';
for($j=1900;$j<$year_limit;$j++){
echo"<option value='$j'>$j</option>";
}
echo '</select>';
echo '</td>';
echo '<td>';
echo '<select name="guest['.$i.']['.$sex.']" id="sex'.$i.'">';
echo '<option>Female</option>';
echo '<option>Male</option>';
echo '</select>';
echo '</td>';
echo '</tr>';
//echo '</div>';
}
echo '</table>';
}
else{
echo '<table border="1">';
echo '<th>First Name</th>';
echo '<th>Surname</th>';
echo '<th>Day of Birth</th>';
echo '<th>Month of Birth</th>';
echo '<th>Year of Birth</th>';
echo '<th>Sex</th>';
echo '<th>Table</th>';
echo '<th>Seat</th>';
echo '<th>Menu</th>';
//echo '<div id="volunteer">';
echo '<tr>';
echo '<td>';
echo $_SESSION['volunteer']['first_name'];
echo '</td>';
echo '<td>';
echo $_SESSION['volunteer']['surname'];
echo '</td>';
echo '<td>';
echo $_SESSION['volunteer']['dob_day'];
echo '</td>';
echo '<td>';
echo $_SESSION['volunteer']['dob_month'];
echo '</td>';
echo '<td>';
echo $_SESSION['volunteer']['dob_year'];
echo '</td>';
echo '<td>';
echo $_SESSION['volunteer']['sex'];
echo '</td>';
echo '</tr>';
//echo '</div>';
}
echo '</table>';
echo '<input type="submit" value="Submit">';
echo '</form>';
}
else{
print '<script type="text/javascript">';
print 'alert("You have not successfully logged in '.
$_SESSION['volunteer']['first_name'].'")';
print '</script>';
}
?>
</body>
Here's my code for processing the details (guests_.php):
<?php
$error = "";
if($_POST){
//$guests = array();
$guests = isset($_POST['guest']) ? $_POST['guest'] : null;
if($guests){
foreach($guests as &$guest){
$guest['first_name'] = ucwords(strip_tags($guest['first_name']));
$guest['surname'] = ucwords(strip_tags($guest['surname']));
$guest['dob_day'] = ucwords(strip_tags($guest['dob_day']));
$guest['dob_month'] = ucwords(strip_tags($guest['dob_month']));
$guest['dob_year'] = ucwords(strip_tags($guest['dob_year']));
$guest['sex'] = ucwords(strip_tags($guest['sex']));
}
}
foreach($guests as $guest){
$date = $form->create_date($guest['dob_day'], $guest['dob_month'], $guest['dob_year']);
$exist = $form->user_exists($guest['first_name'], $guest['surname'], $date, $guest['sex']);
if($exist != ""){
$error .= $exist;
}
}
if($error == ""){
//$_SESSION['existent_guests'] = FALSE;
$_SESSION['guests'] = $guests;
$form->set_guests($_SESSION['guests']);
//$form->set_volunteer($_SESSION['volunteer']);
header("location: tables.php");
exit();
}
}
?>
