Please, take a look to the following code.After clicking Next it goes to overview.php.Why when I click back on my browser to return to this page again, it is not returning back? When I click back I receive "Confirm Form Resubmission" message. After refreshing page it loads page.
I guess problem is in "session_start();" part. Something to do with cookies.
Please, help me it is very urgent for me.

<?php
session_start();

echo "<html>
<head>
<title>Hello World</title>
<meta http-equiv='Content-Type' content='text/html; charset=Windows-1252'/>
</head>";

require_once ('functions.inc');

if(!isset($_POST['userid'])) {
echo "<script type='text/javascript'>";
echo "window.location = 'index.php'";
echo "</script>";

exit;
}else{

session_register("userid", "userpassword");
$username = auth_user($_POST['userid'], $_POST['userpassword']);

if(!$username) {
$PHP_SELF = $_SERVER['PHP_SELF'];
session_unregister("userid");
session_unregister("userpassword");
echo "Authentication failed " .
"Please, write correct username or password. " .
"try again ";
echo "<A HREF=\"index.php\">Login</A><BR>";
exit;
}
}

function auth_user($userid, $userpassword){
global $default_dbname, $user_tablename;
$user_tablename = 'user';
$link_id = db_connect($default_dbname);
mysql_select_db("d12826", $link_id);

$query = "SELECT username FROM $user_tablename WHERE username = '$userid' AND password = '$userpassword'";
$result = mysql_query($query) or die(mysql_error());

if(!mysql_num_rows($result)){
return 0;
}else{
$query_data = mysql_fetch_row($result);

Problem With Back Button. Help?!

View Content

I have tried to create a back button, but I have not reached the correct solution.
I log into first page (index.php) and then you will get two new buttons that brings me to two different pages. Then I want to come back to the login page, the session is gone and I have to log in again. I want to remain logged in when I get to the index page and be able to see the two buttons. I tried different things such as:

Code: [Select]
<input type="button" value="Return to previous page" onClick="javascript:history.go(-1)" /> Code: [Select]
<?php $referer = $_SERVER['HTTP_REFERER'];
   if (!$referer == '') {
      echo '<p><a href="' . $referer . '" title="Return to the previous page">« Go back</a></p>';
   } else {
      echo '<p><a href="javascript:history.go(-1)" title="Return to the previous page">« Go back</a></p>';
   }
?>
But that's not what I'm thinking about. How can I solve this?

index.php

<?php
session_start();

if(isset($_POST['LoutBtn']))
{
session_destroy();

}

if(isset($_POST['LoginBtn']))
{

//convert a string to all lower case letters.
//if user gives username with big letters still can login.
$user = strtolower($_POST['username']);
$pass = $_POST['password'];

if($user == 'admin' && $pass == '123')
{

$_SESSION['LogedIn'] = true;
{

print('Welcome admin');

?>

</form>

</table>

<?php

}
}
elseif (empty($user) || empty($pass))


      {
  print('<font color="#FF0000">Please fill in username and password!<br/></font>');


      }

      }

      elseif ($_POST['password'] != '123'){


      print('<font color="#FF0000">wrong password<br/></font>');

//elseif {

// print('<font color="#FF0000">The User Name And/Or Password is incorrect!
//  Please try again...<br/></font>');

//print('<a href="index.php">Back</a>');
}

Pure Php Back Button

I have found a point in my site where the user may wish to go back a page. Using the back button in the browser works perfectly fine. However, for aesthetical reasons and for "obvious function" reasons i need to create a button on the page which goes back a step in the browsers history.

I know I can do this with Javascript, but I would rather get it done with php first.

Therefore is it possible to create a back button in PHP. The back button in question will go back one step in the browsers history to the same .php it is currently on but in a previous state.

I found this from google, http://www.webmasterworld.com/forum88/870.htm, but then found there was some js in the answers.
I cannot find any other posts similar to this in php freaks

Back-button Error

I am getting strange behavior after a user submits a comment.

After they comment on an article, I display a success message with two buttons: "Return to Article" and "Go to Home Page"

Each button seems to work, and I was even able to "Return to Article" and then hit my browser's Back button to return the original "You Comment was Added" message, but if I hit the Back button after hitting "Go to Home Page" I got this error...

Quote

Notice: Undefined index: pageTitle in /Users/user1/Documents/DEV/++htdocs/01_MyProject/add_comment.php on line 39
Call Stack

On Line 39 I have this code...

Code: [Select]
// Set Page Title.
$pageTitle = $_SESSION['pageTitle'];

It seems to me that if a user hits the Back button in general it will often cause problems, so is there a way to handle this??

I'm not exactly certain is causing the error above in the first place since my SESSION should be intact....

Php Reloading When Clicking Back Button

Similar Tutorials

So, I just don't know where to post this question. I've written a quiz program where 50 English vocab words are pulled from a dB and displayed on one page with the order scrambled. My students then type the Spanish translation for each. When they submit the form the next page grades their work. They have to get a 90 or better for the grade to be automatically recorded, so I want them to click the back button and go back and make corrections. The problem is when they use a Chrome browser and click the back button the program re-sorts the order of questions. It leaves the order of their answers the same. So what they answered for number 1 is still in the field for number 1, but the questions (the English vocab word) is different. Chrome does this consistently so I thought this was a Chrome issue only. Then one of my students said the same thing happened to her when using Safari.

So here is my question, how can I stop Chrome (or any other browser) from re-running my server-side PHP scripts (re-sorting the vocab array) when clicking the back button?

Here is the code for students taking the quiz:

<form method="post" action="portal.php?load=vquiz_grade" style="margin-left: 50px; line-height: 30px;">
<table>
   <?
   $count = 1;
   $query = "SELECT * FROM inno_memorize WHERE uname = 'admiralq' AND subject = '$subject' AND title = '$title' ORDER BY subject, title";
   $result= mysql_query($query) or die("Could not perform query: ".mysql_error());
   while ($row = mysql_fetch_array($result)){
       $ans[$count]['def'] = $row['definition'];
       $ans[$count]['word'] = $row['vocab_word'];
       $count++;
   }

   $max = $count-1;
   shuffle($ans);

   $count = 0;
   while ($count < $max){

       // Search for () and eliminate along with contents
       $loc1 = strpos($ans[$count]['word'], "(");
       $loc2 = strpos($ans[$count]['word'], ")");


       if ($loc1 != "" AND $loc2 != ""){

           // string length
           $length = strlen($ans[$count]['word']);
           // from loc2 to end
           $lcount = $length - $loc2;

           // Dump location points and all text inbetween
           $ans[$count]['word'] = substr($ans[$count]['word'], 0, ($loc1-1)).substr($ans[$count]['word'], ($loc2+1));

       }
       print "<tr><td>".($count+1).". <textarea id=\"kelp".$count."\" cols=25 rows=1 name=\"answer".$count."\" style=\"resize: none;\" autocomplete=\"off\"></textarea> </td>";

       print "<td>".$ans[$count]['def']."</td>";

       print "<td><input type=\"hidden\" name=\"correct".$count."\" value=\"".$ans[$count]['word']."\"></td>";

       ?>
       <td>
           <span style="margin: 0px 0px 20px 50px;">
           <button type="button" onclick="insertAtCursor('kelp<?print $count?>', 'á');">á</button>
           <button type="button" onclick="insertAtCursor('kelp<?print $count?>', 'é');">é</button>
           <button type="button" onclick="insertAtCursor('kelp<?print $count?>', 'í');">í</button>
           <button type="button" onclick="insertAtCursor('kelp<?print $count?>', 'ó');">ó</button>
           <button type="button" onclick="insertAtCursor('kelp<?print $count?>', 'ú');">ú</button>      
           <button type="button" onclick="insertAtCursor('kelp<?print $count?>', 'ñ');">ñ</button>
           <button type="button" onclick="insertAtCursor('kelp<?print $count?>', '¿');">¿</button>
           <button type="button" onclick="insertAtCursor('kelp<?print $count?>', '¡');">¡</button>      
           </span>
       </td>
       </tr>
       <?

       //print "<br>";
       $count++;
   }

?>
</table>

And here is the code showing them what they missed.

<?
$count = 0;
$wcount = 0;
$rcount = 0;

//   Total grade
while ($count < $max){
   if (trim(strtolower(${'answer'.$count})) == trim(strtolower(${'correct'.$count}))){$rcount++;}

$count = 0;
$wrong = 0;

print "<table>";
print "<tr><td height=\"10\"></td></tr>";
while ($count < $max){

$tcolor = "0a0a0a";

   // Grade response and set color
   if (trim(strtolower(${'answer'.$count})) == trim(strtolower(${'correct'.$count}))){$tcolor = "ff7777";}

       print "</tr>";
       $wrong = 0;
   }

   $count++;

       }

   }

Hey, I made a register page and its all working great.

I want to have a "Back" button when the user submits the form if password1 & password2 do not match or username allready exists. But trying to put one in after the echo command isn't working for me. Can anyone help?

Heres the error I recieve: Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in /home/jamiew90/public_html/Staff/register.php on line 49

Heres line 49 & the surrounding lines incase needed, line 49 is the one beginning with echo:
//none were left blank!  We continue...
if($password != $cpassword) {

// the passwords are not the same!
echo "<br><br><b>Passwords do not match</b> <p> <FORM><INPUT TYPE="button" VALUE="Back" onClick="history.go(-1);return true;;"> </FORM>";";

}else{

// the passwords are the same!  we continue...

Is it possible to even add a back button after echo?
Thanks for the help

not sure if this will find an answer but I am posting anyway. Any help is appreciated....my coder has left the team and no matter how I invite her to come and do some bug squashing, her new schedules won't fit a re-visit into my little aplication...I am eager to delve into the codes at my very low knowledge of php. I have initiated reading and is still trying to teach myself...but of course not as fast as the app needs the patch...here's the meat:

Need Help With A Script That Sends Information Back To Ajax

Similar Tutorials

View Content

I'm working on learning AJAX, all is fine with that script as it's from a book. The issue I'm having is the PHP server side code to get a response from the server. I'm still rather new to all of this so try to explain any response given in a noob friendly manner.

So I have the following so far:

  // Connection Values
  $dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

// Get the variable sent by AJAX script
if (isset($_GET['username'])) {
// Secure the information
$passname = mysqli_real_escape_string($dbc, trim($_GET['username']));
// Lookup the username in the database
      $query = "SELECT username FROM information WHERE username = '$passname'";
      $data = mysqli_query($dbc, $query);
    // Allow some time to get the response
sleep(2);
  // If 1 is returned that name exsists, if 0 then we can move forward
      if (mysqli_num_rows($data) == 0) {
     // Send okay back to the ajax script so it knows to stop bothering the user
echo 'okay';
} else {
   // Send denied back to the ajax script so the user knows that name is taken
echo 'denied';
}
}

Code "back" Button To Retain Values From $_post

Hi,

I have set up 2 php pages

page 1 - add_entry2.php
In this page I have a invoice table created where I can dynamically add/delete rows. This has a View Bill button which takes me to page 2- add_entry3.php
In this page it shows up the rows added in page 1 in read only format, so if the user wants to modify the data that he/she entered then he must Click on <back> that i have provided in the page 2 which will direct him to page 1

Now the problem starts here
on click of Back the dynamically added rows dissappear..which is frustrating..I know its something to do with my code..but can anyone help me fix it.

One more thing is that i dont want to store the data into DB till the finalise button is clicked on page 2 so that means till page 2 is submitted nothing goes to DB from Page 1.

I am able to retain values if I use the code Code: [Select]
<form action="add_entry2.php" name="eval_edit" method="post" format="html">
i,e if I submit back to the same page and retrieve values form $_POST

but If I use the code Code: [Select]
<input type="button" value="Back" onClick="history.go(-1);return true;">to get back to add_entry2.ph it looses all the values. Is there any other way to code the BACK link retaining my $_POST values(Do you think $_SESSION would work in this case?)
