Hello,
I am pretty new to php and i am trying my hands on something little but i"m getting a persistent error.
I am trying to insert a record into the database but i keep getting the error saying the record wasn't inserted.
i checked the databse and there's really nothing there.

Below is the php code. Please let me know the error and guide me through the changes.

<?php 
//function submit(){
// Define database credentials
$host = 'localhost';
$user = 'admin';
$password = '12345';
$database = 'staff_db';
// Create db connection
$conn = mysql_connect($host,$user,$password) or die('Error: Could not connect to database - '.mysql_error());
// Once connected, we can select a database
mysql_select_db($database,$conn) or die('Error in selecting the database: '.mysql_error());

// Grab user input and sanitize 
$title = mysql_real_escape_string(filter_var(trim($_POST['Title']), FILTER_SANITIZE_STRING));
$fname = mysql_real_escape_string(filter_var(trim($_POST['FirstName']), FILTER_SANITIZE_STRING));
$mdname = mysql_real_escape_string(filter_var(trim($_POST['MiddleName']), FILTER_SANITIZE_STRING));
$lname = mysql_real_escape_string(filter_var(trim($_POST['LastName']), FILTER_SANITIZE_STRING));
$res_add = mysql_real_escape_string(filter_var(trim($_POST['Resid_Add']), FILTER_SANITIZE_STRING));
if(! $res_tel = mysql_real_escape_string(filter_var(trim($_POST['Resid_Tel']), FILTER_SANITIZE_NUMBER_INT)))
{
	echo 'Please enter a valid telephone number.';
	};
if(! $mobile = mysql_real_escape_string(filter_var(trim($_POST['Mobile']), FILTER_SANITIZE_NUMBER_INT)))
{
	echo 'Please enter a valid mobile number.';
	die();
	};
//$frmstaff_status = mysql_real_escape_string(filter_var(trim($_POST['frmStaff_Status']), FILTER_SANITIZE_STRING));

// Validate the user email
if(! $email = filter_var(trim($_POST['Email']), FILTER_VALIDATE_EMAIL))
{     
    echo 'Please enter a valid email.';
    die();
}

$sql = 'INSERT INTO `$database`.`Emp_Details` (
`Title` ,
`First_Name` , 
`Middle_Name`,
`Last_Name` ,
`Res_Add` ,
`Res_Tel` ,
`Mobile` ,
`Email` 
)
VALUES (".$title." , ".$fname." ,  ".$mdname.", ".$lname.", ".$res_add.", ".$res_tel.", ".$mobile.", ".$email.")';

if(mysql_query($sql))
{
    echo 'User information saved successfully.';
}else
{
    echo 'Error: We encountered an error while inserting the new record.';
}
mysql_close($conn);
//}

?>

Thanks.

You should use mysql_error() to see the reason why the query failed, but my guess is that it will say something like "table $database.Emp_Details does not exist".

You have used single quotes to surround your query, but PHP does not replace variables inside a single-quoted string - use double-quotes, or concatenate strings using the "." operator.

What does the error message you got from mysql_error() say?

If you converted the outer quotes to double-quotes, did you then single-quote the values in the query?

sum of all the fields in columns. where columns are dynamic

I would like to get the sum of all the fields in columns. where columns are dynamic even the rows are dynamic.
Hi here in my table the user can add column's dynamically, so i won't be knowing the columns name to raw code initially as $row['SUM(price)']. Hence I need a query which can pull by itself all the column values

Even if you don't know how many column and how many rows are there going to be even though you can establish certain rule. Try to establish the rule. and you can browse all row and column through javascript

I wish I could believe there is an after life.

You have the right syntax for doing that in your example.

There are some helpful functions for working with classes: Class functions[^].
The class_exists[^] function is useful for checking if you have a valid class name.

How much time does it take to be a great developer in PHP?

Hello masters of web developing. I have an average experience in C# and I like to know that how much does it take to be a great developer in PHP by considering that I put my time on this 24/7. Why I didn't choose ASP.NET is that I think it is much time consuming than learning PHP and I like to work with current famous CMSes like Wordpress and Drupal.

Dispensing text from a text file

In my php file called "account.php" I have

XML

  <?php

    // First we execute our common code to connection to the database and start the session
    require("common.php");

    // At the top of the page we check to see whether the user is logged in or not
    if(empty($_SESSION['user']))
    {
        // If they are not, we redirect them to the login page.
        header("Location: login.php");

        // Remember that this die statement is absolutely critical.  Without it,
        // people can view your members-only content without logging in.
        die("Redirecting to login.php");
    }

?>
<html>
<body>
<link rel="icon" type="image/gif" href="favicon.gif" />
<?php include("header.php"); ?>
<div id="main-box">
<ul>
<li class="buttons">
<?php
TEXT BOX WITH A LINE FROM **TEXT.txt** SHOULD APPEAR HERE AFTER USER CLICKS BUTTONS
<input type="button" name="account" value="Get Your Account" onclick="#" />
</li>
</ul>
</div>
</body>
</html>

I want it so when the user clicks the button, a text box appears and displays ONE line from the text file and when they view it, it deletes it from the text file.

text.txt

Eddie
Apples
Hello
People

So after the user clicks the button it displays "Eddie" line to them and then deletes it after the user sees it so that the next line "Apples" would then become the first line.

If you don't understand my question then please let me know and I will try to explain further. Thank you. Smile | :)

I make a little login example...

In the index.php :

HTML

<html>
  <head>
    <!-- INCLUDE HERE THE JQUERY 1.7.2 LIBRARY -->
  </head>
  <body>
    Username:<input id="input-username" type="text" maxlength="100" />
    Password:<input id="input-password" type="password" maxlength="16" />
    <input id="btn-ok" type="button" value="OK" />
  </body>
  <script type="text/javascript">
    $('#btn-ok').click(function() {
      var DataToSend = new Object();

      DataToSend.username = $('#input-username').val();
      DataToSend.password = $('#input-password').val();     

      $.post('validate.php',DataToSend,function(data) {
        
        if(data == 'ok')
          alert('Login OK!');
        else
          alert('Login ERROR!');

      });
    });
  </script>
</html>

You just make a post to a php file "validate.php" and there you validate the login, and make querys to the DataBase and return a value, and you are doing that all without refresh the page!
