all code is working and data insert successfully and show but if you see above first file i am using mysql,i want to use mysqli but issue is that when show $conn as a global variable (because mysqli needed 2 parameters) and use in mysqli($sql,$conn),error show undefined variable $conn why?
Use $this for access variables in your class
define('DB_SERVER','localhost');
define('DB_USER','root');
define('DB_PASS' ,'');
define('DB_NAME', 'dbtuts');
class DB_con {
private $conn;
function __construct() {
$this->conn = mysqli_connect(DB_SERVER,DB_USER,DB_PASS) or die('localhost connection problem'.mysql_error());
mysqli_select_db($this->conn, DB_NAME);
}
public function insert($fname,$lname,$city) {
$sql = "INSERT users(first_name,last_name,user_city)VALUES('$fname','$lname','$city')";
$res = mysqli_query($this->conn, $sql);
return $res;
}
public function select() {
// $db=new DB_con();
// $db->__construct();
$sql = "SELECT * FROM users";
$res = mysqli_query($this->conn, $sql);
// return $conn;
return $res;
}
}

in same code if change the table name it just work fine
Then I would make sure you're connected to the right database. It's surprisingly common for developers to have multiple versions of their database, either on different MySQL instances or else on the same instance under a different schema name. Then they get mixed up, connecting to one database with MySQL Workbench while their app is connecting to a different database.
I would advise that you temporarily add a query to your page to run SHOW TABLES and then dump the result of that query to the log, to confirm that the mcb_department table is present in the database that your PHP script is connected to.
$deptQuery = "Select * from mcb_department";
echo mysql_real_escape_string($deptQuery);
mysql_query($deptQuery);
Where's your error checking? You need to check the return value of mysql_query() every time you run a query, so if there's a problem, you output the error message to your log. Only this way can you start to solve some of these problems.
$result = mysql_query($deptQuery);
if (!$result) {
trigger_error("Error in file " . __FILE__ . " near line " . __LINE__
. " for query $deptQuery: " . mysql_error());
die("Database error");
}
PS: The advice of some commenters that mysql_* functions are deprecated is true, but probably irrelevant to your question. Folks who focus on the API, when you have said the API is working, are just being pedantic.
I have added update and delete button in the same form using following codes. Deletion is working perfectly. But updating is again not taking the value of "id".
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dp = "tool";
$dp= new mysqli($servername, $username, $password, $dp) or die("Unable to connect");
//echo"Great work";
?>

$disease = $_POST['Disease'];
$SubDisease = $_POST['SubDisease'];
$Associated_Disease = $_POST['Associated_Disease'];
$Ethinicity = $_POST['Ethinicity'];
$Source = $_POST ['Source'];
$id = $_POST ['id'];
$update= "Update disease set Disease='".$disease."', SubDisease='".$SubDisease."', Associated_Disease='".$Associated_Disease."', Ethinicity='".$Ethinicity."', Source='".$Source."' where id=".$_POST["id"];
if(!mysqli_query($conn,$update))
echo mysqli_error;
?>
And drop down of Disease, is also not getting reading the databse value and not getting display in the editing page.
It's me again, sorry...
I've been looking for the answer right in this forums, but there are no posts has been solved. I don't know if the questioner has been resolved the problems and not given a solved comment or something like that. All the comments/replies from the questioner is 'not work' or 'get some new errors' ect.
Now my scripts has worked before I put pagination scripts on them, but again errors in 'mysqli'. The errors are:
Warning: mysqli_query() expects at least 2 parameters, 1 given in C:\xampp\htdocs\paging\index.php on line 8
Warning: mysqli_fetch_row() expects parameter 1 to be mysqli_result, null given in C:\xampp\htdocs\paging\index.php on line 9
My scripts contained two files:
index.php:
<?php
$con = mysqli_connect("localhost", "root", "", "db_book") or die(mysqli_error($con));
$per_page = 3;
//getting number of rows and calculating no of pages
$sql = "SELECT COUNT(*) FROM flipbook";
$result = mysqli_query($sql);
$count = mysqli_fetch_row($result);
$pages = ceil($count[0]/$per_page);
?>

Thanks again...thank you...
best regards,
The error message is quite descriptive and clear: The first parameter to mysqli_query should be the connection handle.
Instead of $result = mysqli_query($sql);, use $result = mysqli_query($con, $sql);
I have an editable grid where I want to edit the CSS such that the textarea to show the maximum width, but somehow I can't increase the width of the text area.
My database has three columns:
ID
Name
Gossip
I'm retrieving everything and displaying it in an editable grid using PHP.
index.php code
<?php
$db = new mysqli('localhost', 'root', '', 'bollywood');
$db->set_charset('utf8');
if ($db->connect_errno) {
die('Check the database connection again!');
}
$userQuery = 'SELECT Id,Name,Gossip FROM bollywood';
$stmt = $db->query($userQuery);

You doing it wrong
<td ><input type="textarea" cols="500" rows="100" value="<?php echo $row['Gossip']; ?>" /></td>
Should be:
<td ><textarea cols="500" rows="100"><?php echo $row['Gossip']; ?></textarea>
textarea is html tag name but not input type. so change this.
<td ><input type="textarea" cols="500" rows="100" value="<?php echo $row['Gossip']; ?>" /></td>
to
<td ><textarea cols="500" rows="100"><?php echo $row['Gossip']; ?></textarea>
also add this css.
<style>
textarea {
resize: both;
width:700px;
}
</style>
also are you sure that you can get content using this.
<?php echo $row['Gossip']; ?>
