PHP + MySQL - will not read from database - php

I'm making a website project for school which requires a log in page. I already have the PHP set up to write to the database, that works no problem. My new problem is that nothing will actually read from the database. I am testing on my localhost, connection is fine. My error I receive is that the email is incorrect, when in fact it is valid. Hopefully you guys can pick up on an easy problem for me! Thanks!
PHP:
<?php
//Setup our DB connection
include('../../connect/local-connect.php');
// Get the user entered elements
$email = $_POST['email'];
$pword = $_POST['password'];
// email query
$query = "SELECT email FROM project WHERE email = '$email'";
//Run email query
$result = mysqli_query($dbc, $query) or die('Read error - email');
// # of results
if (mysqli_num_rows($result) == 0)
{
header('Location:login.php?logerror=1');
exit;
}
//If we got here, we have validated the email
// Build the username query
$query = "SELECT * FROM project WHERE email = '$email' AND password = '$pword'";
// Run the password query
$result = mysqli_query($dbc, $query) or die('Read error - password');
// Did we get a row?
if (mysqli_num_rows($result) == 0)
{
header('Location:login.php?logerror=2');
exit;
}
// If we got here, we have validated an email and password combo.
// Close the DB connection
mysqli_close ($dbc);
// Start a PHP session
session_start();
//Get and store our session variables
$row = mysqli_fetch_array($result);
$_SESSION['sname']=$row['name'];
header('Location:custwelcome.php');
exit;
// Pass a '3' back to login.php for testing (Keep this code at the bottom!)
header('Location:login.php?logerror=3');
exit;
?>
HTML:
<!DOCTYPE html>

<?php
// Start a PHP session
session_start();
// Check to see if user is already logged in
if(isset($_SESSION["sname"]))

Let me know if any more files need to be looked at I just figured the issue lay in these two files.
MY SOLUTION: All I did was change my table name and it somehow started to work. So that's good, I guess! Thanks to everyone who tried to help :)

is your database connection ok? at first check is connection establish perfectly.
an on top of database connection file please on error reporting to find out error
error_reporing(E_ALL);
ini_set('display_errors',1);
and after database connection use following syntax.. you will get all if any failure in connection
mysql_connect('host','username','password') OR die(mysql_error());
mysql_select_db('dbName') OR die(mysql_error());

<?php
$con=mysqli_connect("host","username","password","my_db");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>
for mysqli

How can i get PHP login script to log users in correctly?

I am new to PHP and I am trying to develop a simple login system where it echoes a success message and redirects to a secure page and when details are wrong, it echoes an error message and reloads the login form.
I have been trying to for a while now and cannot figure it out, even though I have some functionality in terms of it directing to the correct page.
My database on PhpMyAdmin is correctly configured. Also, any help on sessions would be greatly appreciated.
PHP CODE:
<?php
$servername = "localhost";
$username = "root";
$password = "cornwall";
$con=mysqli_connect('localhost','root','cornwall','ibill');
// This code creates a connection to the MySQL database in PHPMyAdmin named 'ibill':
$username = $_POST['username'];
$password = $_POST['password'];
//These are the different PHP variables that store my posted data.
$login="SELECT * FROM users WHERE username='$username' AND password='$password'";
$result=mysqli_query($con, $login);
$count=mysqli_num_rows($result);
//This is the query that will be sent to the MySQL server.
if($count==1)
{
header('Location: http://localhost/projects/ibill_v3/html/main.html#home');
exit();
}
//This checks the 'user_details' database for correct user registration details and if successful, directs to home page.
else {
header('Location: http://localhost/projects/ibill_v3/html/loginform.html');
echo "Wrong details";
exit();
}
//If login details are incorrect
/** Error reporting */
error_reporting(E_ALL);
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
?>

The above is going to redirect before your echo statement is reached, so nothing will be displayed.
Secondly, the following line:
<form data-ajax="false" method="POST" action="loginform.php" > will not send any data back to your file containing the form if you're using echo statements. It is going to redirect to the loginform.php and will stay there if you do not explicitly redirect back the page with your form.
Instead, use:
<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> as your form's action. And then include your loginform.php somewhere before the form in your HTML.
This is going to send data back to the form's file and replaces special characters to HTML entities (for security), it also allows you to use echo's or variables to return messages to the user.
loginform.php will need to check if specific inputs are posted:
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
if($_POST['username'] && $_POST['password'])
{
//do work
}
}
Here is a basic php form tutorial to start you off: php tutorial
I think it's because your redirecting to the same page with no post. I didn't look through all the code, that is just my first stab at it
This will not appear on loginform.html:
echo "Wrong details";
Use something like:
$_SESSION['errorMessage'] = "Wrong details";
header('Location: http://localhost/projects/ibill_v3/html/loginform.html');
exit();
And then on loginform.html, add this code to display the error message:
if(isset( $_SESSION['errorMessage'])) echo $_SESSION['errorMessage'];

Login Form header() shows blank page

You are checking whether $_POST['Submit'] is set.
However, in your form, the name attribute is Submit with an extra space:
<input id="Submit" name="Submit "type = "Submit" class="btn"/>
This might be the cause of the problem, since you said it shows me a blank page.
also - you have no method listed for your form, but are checking the $_POST array to check for "Submit". It should be:
<form method="POST" action="holderlogin.php">
Don't know if its causing your problem, but you have a leading space before the php declaration - this can be cause problems to the php rendering if you are setting header requests later in the code - there can be no characters rendered before the header request.
<?php
also you list the action of the form as "holderlogin.php"
but list the name of the file as "Holderlogin.php" - this might just be a typo when entering the code here but worth checking.

PHP contact form not working and giving errors

I am trying to set up a contact form at:
http://48hrcodes.com/contact.php
however I am trouble getting it to work.
Here is the code I am using:
<?php

*
* $empty_fields_message and $thankyou_message can be changed
* if you wish.
*/
// Change to your own email address
$your_email = "";
// This is what is displayed in the email subject line
// Change it if you want
$subject = "48hrcodes contact form";
// This is displayed if all the fields are not filled in
$empty_fields_message = "<p>Please go back and complete all the fields in the form.</p>";
// This is displayed when the email has been sent
$thankyou_message = "<p>Thank you. Your message has been received.</p>";
// You do not need to edit below this line
$name = stripslashes($_POST['txtName']);
$email = stripslashes($_POST['txtEmail']);
$message = stripslashes($_POST['txtMessage']);
if (!isset($_POST['txtName'])) {

I get errors at the top of the page, as well as when i submit the form, the email i get only has the messagebox text, not the name or email.
I have tried everything i could think of, however it still fails to send anything except the msg variable.
Thanks :)
change
$name = stripslashes($_POST['txtName']);
$email = stripslashes($_POST['txtEmail']);
$message = stripslashes($_POST['txtMessage']);
To,
$name = (isset($_POST['txtName']))?stripslashes($_POST['txtName']):"";
$email = (isset($_POST['txtEmail']))?stripslashes($_POST['txtEmail']):"";
$message = (isset($_POST['txtMessage']))?stripslashes($_POST['txtMessage']):"";
To avoid the warnings at the top.
Use
like this
if(isset($_POST['txtName'])
{
$name = stripslashes($_POST['txtName']);
}

Check your brace positions after your if statements. You check for empty values, but you don't alter the program flow in a meaningful way if you find them.
Also, replace your curly quotes with real quotes. And check for SQL injection. And double-check your MySQL call. You'll get an error from PHP before you'll ever get $msg echoed, based on the way things are written.

Form Validation Error Message not showing

Was hoping for some fresh eyes on this. I've got a page which will add a new event to a database. All 3 fields are required, so if they are empty when the submit button is pushed the error message should appear. Anyone know why it isn't showing the error message? Thanks in advance!

You have the submit name as "submit_event"
So you must use
if (isset($_POST['submit_event'])) {
.

Hope it helps
Try adding
<input type="hidden" name="submit" value="1" />
to your form. The $_POST array does not have a 'submit' value in the code you have provided, so it's just going to display the form again.
