Page Control

OldManRiver · September 28, 2006

All,

Trying to read through all the manuals to determine how control is returned to the calling page for the following scenario:

[code]<form method=post action=myproc.php>[/code]

without using the

[code]header(Location:mypage.php)[/code]

in the myproc.php file.

Not finding anything! Anybody help please!

What's the problem with using header()?

Also, you could simply use the form page itself to process the form data.

You're missing some quotation marks there btw.

Well everytime I've tried to use the [b]header[/b] command, the page re-inits and my var values get scrubbed, so can't transfer processed var values, even with [b]global[/b] on for that vars I'm trying to tranfer.

If you have a better way, let me know!

Sorry, I'm lost. You want to return to the form page after submitting the form?

What I have is:

[b]First Pass:[/b]
[code] $display_block = "<form action='../scripts/login.php' method='POST'><p><strong>User Login:</strong><br>
<INPUT TYPE='text' NAME='username'></p><p><strong>Password:</strong><br>
<INPUT TYPE='password' NAME='password'></p><p> <br>
<input type=image src='../Images/btn-pale(log).jpg' name=log value=log width=120>
</form>";[/code]

[b]Second Pass with Success:[/b]
[code] $display_block = "<font size=-1><b>Welcome $f_name $l_name.
<br>Thank you for logging in!</b></font>";[/code]

[b]Second Pass with Failure:[/b]
[code] $display_block = "<font size=-1><b>Login not successful!</b></font>";[/code]

The $display_block sets on first pass, but does not set on second. When I use [b]header[/b] it sees the runs as first pass and resets everything, so can not get the transfer.

Should be simple, but it isn't.

How do you know whether a user is logged on or off anyway?

HuggieBear · September 28, 2006

OK, you're possibly best using just one page here...

Call the page something like login.php and set it up a little like this...

[code]
<?php

// Set any default variables, I've put these here to show you as an example
$username = "HuggieBear";
$password = "myPassword";

// Work out what to do next
if (!isset($_GET['submit'])){ // if it's the first time the page has been called then display the form
showForm(); // Just a call to the function further down
}
else { // if the submit button's been pushed
if (($_POST['user'] == $username) && ($_POST['pass'] == $password)){
echo "Authenticated OK"; // Show this if the submitted username and password match up with what we have
}
else {
echo "We couldn't authenticate you, please try again"; // Show this and the form if they failed to enter the correct details
showForm();
}
}

// Function to show the form
function showForm {
echo <<<HTML
<h1>$message</h1>
<form name="login" action="{$_SERVER['PHP_SELF']}" method="POST">
<input type="text" name="user">
<input type="password" name="pass">
<input type="submit" name="submit" value="submit">
HTML;
}
[/code]

Per complete code as follows:[code]<?php
// check for required fields from the form
if (isset($_POST['log'])) {
//connection to server and select database
require ('../scripts/db_connect.php');
// create and issue the query
$sql = "select usr_id, usr_name, usr_pwd from log_user where usr_name =
'$_POST[username]' AND usr_pwd = '$_POST[password]'";
$result = mysql_query($sql,$conn) or die(mysql_error());
if (mysql_num_rows($result) == 1) {
$f_uid = mysql_result($result, 0, 'usr_id');
$sql = "select inf_id from user_idx where usr_id=$f_uid";
$residx = mysql_query($sql,$conn) or die(mysql_error());
if (mysql_num_rows($residx) == 1) {
$f_inf = mysql_result($residx, 0, 'inf_id');
$sql = "select inf_fnam, inf_lnam from user_info where inf_id=$f_inf";
$resinf = mysql_query($sql,$conn) or die(mysql_error());
}
// if authorized, get the value of f_name l_name
$f_name = mysql_result($resinf, 0, 'inf_fnam');
$l_name = mysql_result($resinf, 0, 'inf_lnam');
// set authorization cookie
setcookie("auth", "1", 0, "/", "localhost @mydomain.com", 0);
//create display string
$display_block = "<font size=-1><b>Welcome $f_name $l_name.
<br>Thank you for logging in!</b></font>";
echo $display_block;
} else {
$display_block = "<font size=-1><b>Login not successful!</b></font>";
// return;
// exit;
}
} else {
$display_block = "<form action='../scripts/login.php' method='POST'><p><strong>User Login:</strong><br>
<INPUT TYPE='text' NAME='username'></p><p><strong>Password:</strong><br>
<INPUT TYPE='password' NAME='password'></p><p> <br>
<input type=image src='../Images/btn-pale(log).jpg' name=log value=log width=120>
</form>";
}
?>[/code]

SQL code is working fine, but can't return the $display_block to the calling form!

Off topic- the site has a good idea, I would suggest unpixelating your image though.

Not a graphics geek, so don't know how!

There is another site along this line at:

But no front page to it, just a forum in the back.

OK, you're missing the echo statements... See the comments I've made in your code... marked like this [b]// <----[/b]

[code]<?php
// check for required fields from the form
if (isset($_POST['log'])) {
//connection to server and select database
require ('../scripts/db_connect.php');
// create and issue the query
$sql = "select usr_id, usr_name, usr_pwd from log_user where usr_name =
'$_POST[username]' AND usr_pwd = '$_POST[password]'";
$result = mysql_query($sql,$conn) or die(mysql_error());
if (mysql_num_rows($result) == 1) {
$f_uid = mysql_result($result, 0, 'usr_id');
$sql = "select inf_id from user_idx where usr_id=$f_uid";
$residx = mysql_query($sql,$conn) or die(mysql_error());
if (mysql_num_rows($residx) == 1) {
$f_inf = mysql_result($residx, 0, 'inf_id');
$sql = "select inf_fnam, inf_lnam from user_info where inf_id=$f_inf";
$resinf = mysql_query($sql,$conn) or die(mysql_error());
}
// if authorized, get the value of f_name l_name
$f_name = mysql_result($resinf, 0, 'inf_fnam');
$l_name = mysql_result($resinf, 0, 'inf_lnam');
// set authorization cookie
setcookie("auth", "1", 0, "/", "localhost @mydomain.com", 0);
//create display string
$display_block = "<font size=-1><b>Welcome $f_name $l_name.
<br>Thank you for logging in!</b></font>";
echo $display_block;
} else {
$display_block = "<font size=-1><b>Login not successful!</b></font>";
echo $display_block; // <---- This was missing
// return;
// exit;
}
} else {
$display_block = "<form action='../scripts/login.php' method='POST'><p><strong>User Login:</strong><br>
<INPUT TYPE='text' NAME='username'></p><p><strong>Password:</strong><br>
<INPUT TYPE='password' NAME='password'></p><p> <br>
<input type=image src='../Images/btn-pale(log).jpg' name=log value=log width=120>
</form>";
echo $display_block; // <---- This was also missing
}
?>[/code]

Does that help at all?

H,

Echo statements are in the [b]form[/b] file! Do you need source or can you glean from URL?

You can see the $display_block sets in the first pass and you see the input fields and the Login button.

OMR

Ninjakreborn · September 28, 2006

it would be easier for you to get this to work if you would just write out the form in html, maybe even php, but you are making almost everything that is going to hit the screen into a function, it would be easier to keep it simple, for what you are trying to do you could rewrite it in a neater, simpler way and chances are you would fix all of your problems.

HuggieBear · September 28, 2006

Ohhhh.... Lost my head for a minute.

In that case add the following to the top of every page before you output anything to the browser:
[code=php:0]session_start();
[/code]

Change each instance of $display_block to $_SESSION['display_block'];

Then on the form page type:
[code=php:0]echo $_SESSION['display_block'];
[/code]

Easiest way to take things like that between pages is through session variables.

Huggie

Trying to get both these working right.

Forum works good at e-worldpeace.com, but need more substance.

Substance is OK on cleanpoliticalclassifiedrevolution.com, but code bombs.

Need to fix both, so all are happy!

OldManRiver · September 28, 2006

Huggie,

Followed your advise, but now getting an error, which I'm lost on.

Take a look at the error from the URL and please advise!

I put the session_start(); in the [b]form[/b] file but must not be at the right place or maybe it conflicts with something [b]godaddy[/b] is putting up there?

Uploaded the form file, so you can look!

Had it in the proc file at first, and that blew chunks too!

Thanks!

ok, is session_start() at the top of all the pages?

This error is common if you're sending something to the browser before you call session_start().

I tend to make it the first thing on every page by default, e.g.

[code]
<?php
session_start();
include('header.php');
include_once('connect.php')

echo <<<HTML
<html>
<head>
.....
?>
[/code]

If that's not the case, then maybe you could post the first say 25 lines of code for me.

Huggie

Huggie,

Made it the first line in the code, and now get a blank page, basically. Look and see!

HuggieBear · September 28, 2006

Is that a frame at the top of the page?

Huggie

OldManRiver · September 28, 2006

H,

Per your example all the HTML has to have an [b]echo[/b]. It this true?

I don't have it that way so can you look at the uploaded form file and tell me where I screwed myself?

H,

Naw! Customer signed this up with GoDaddy on a paid account, so not supposed to have the ads, but won't kick there butt for config'ing the domain wrong to get a clean page.

Think it's a javascript!

OMR

HuggieBear · September 28, 2006

Your code looks ok, if you added session_start() to the top of login.php you can remove it. I know I said the top of everypage, but as your including it into cleanpcr.php, there's no need to have it twice.
