if its not ñ I'm getting the right result but when I'm using it
UNDEFINED VARIABLE.
here's my approach to search the $location
and all Collation and operation in database is SET to "utf8_general_ci"
<?php
/*$location = $_GET['location'];*/
$location = $_GET['location'];
$result = $db->prepare("SELECT * FROM list WHERE loc = '".$location."'");
$result->execute();
for($i=0; $row = $result->fetch(); $i++){
$title1=$row['title'];
$fname=$row['fname'];
$mname=$row['mname'];
$lname=$row['lname'];
$addr1=$row['addr'];
$post1=$row['position'];
$location=$row['loc'];
}
?>
my connection in db
<?php
include('connect.php');
$db_host = 'localhost';
$db_user = 'root';
$db_pass = '';
$db_database = 'xxx';
$db = new PDO('mysql:host='.$db_host.';dbname='.$db_database, $db_user, $db_pass);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
?>

Trying to make a whitelist system with the arguments below, but It is not echoing anything. The code is not function as it should atm. The problem is that it is not updating it. This is the code:
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "premium";
$key = $_GET["key"];
$user = $_GET["user"];
$id = $_GET["id"];
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$result = mysqli_query("SELECT * FROM `whitelists` WHERE `key` = '$key'");
if( $result === false ) {
echo 'nope';
}
else
{
echo 'yes';
mysqli_query("UPDATE `whitelists` SET `id` = '$id', `user` = '$user' WHERE `key` ='$key' ");
}
$conn->close();
?>
first thing you should do is Use mysqli_* functions or PDO, because your code is Deprecated.
example:
$result = mysqli_query($conn, "UPDATE whitelists SET `id` = '$id', `user` = '$user' WHERE `key` ='$key' ");
Secondly you should use a false statement instead of num_rows.
if($result === false)
{
echo "nope";
}
else
{
// Execute your query here.
}
I've got a weird problem.
I created a website on localhost. Everything was working fine. I could connect to my mysql db without any problems.
I decided to put it on external server to show it to my friends. I changed $username, $dbname etc.
Then I decided to work little with the website back on localhost. And then it started. When I run my script which adds new records to my db (name, message, email) this shows up.
No database selected
Everything is just the same it was before I decided to put it on the server. What can be the problem?
EDIT: Here's the code of connect.php
<?php
$username ="root";
$password = "";
$host = "localhost";
$table = "test";
$conn = new mysqli("$host", "$username", "$password", "$table");
if (!$conn) {
die("Nie udało się połączyć z bazą danych: ".mysqli_connect_error());
}
and here's a script implemented into index.php
<?php
include 'connect.php';
$sql = "SELECT s_id, name, s_like, s_dislike, message FROM suggestions ORDER BY rand()";
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_assoc($result);
$s_id = $row["s_id"];
$s_like = $row["s_like"];
$s_dislike = $row["s_dislike"];
echo '<p>' . $row["message"] . '</p>';
echo '<h1 class="podpis">' . $row["name"] . '</h1>';
mysqli_close($conn);
?>
and here's the cde of comments.php where I see the message about No database selected.
<?php
$name = $_REQUEST['name'];
$email = $_REQUEST['email'];
$message = $_REQUEST['message'];
$username ="root";
$password = "";
$host = "localhost";
$table = "test";
$conn = mysqli_connect($host, $username, $password, $table);
$query = "INSERT INTO suggestions (name, email, message) VALUES ('$name',
'$email', '$message')";
if (mysql_query($query)) {
echo 'Dodano sugestię!';
header('Location: index.php');
} else{ die(mysql_error());}
mysql_close();
?>
I'm trying to show all usernames in the users table onto my index page.
Here is the PHP code:
$result = $db->prepare("SELECT username FROM users");
$result->execute();
while ($row = $db->fetchAll(PDO::FETCH_ASSOC))
{
$user = $row['users'];
$username = $row['username'];
}
echo $user;
echo $username;
I think you are printing username outside of the while loop, so that you're getting the last username every time.
$result = $db->prepare("SELECT username FROM users");
$result->execute();
while ($row = $db->fetchAll(PDO::FETCH_ASSOC))
{
echo $username = $row['username'];
}
Apparently i have something wrong because this query will not execute, Can anyone see why ?
$username=username;
$mysqli = #new mysqli($localhost, $user, $pass, $database);
$sql = "SELECT * FROM player_log WHERE user = '$username'AND log_status=online";
$result = $mysqli->query($sql);
if ($result->num_rows > 0){
echo "its works";
}
Multiple issues see modified code below
Added standard way to call mysqli (space after $username is not an issue)
$username=username;
$mysqli = #new mysqli($localhost, $user, $pass, $database);
$sql = "SELECT * FROM player_log WHERE user = '$username'AND log_status='online' ";
if ($result = $mysqli->query($sql)){
printf("Select returned %d rows.\n", $result->num_rows);
/* free result set */
$result->close();
echo "its works";
}
How i can send $country to second code (select emr_value from countries where country_name='$country') i don't know why $country = "" or null please help
thanks
<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "db";
global $country;
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT meta_value FROM `wp_usermeta` where user_id=$user_id and meta_key='custom_field_6' ";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
$country = $row["meta_value"];
echo $country;
}
} else {
echo "0 results";
}
$conn->close();
?>
Second Code (Here i want to display data for this query (select emr_value from countries where country_name='$country'))
<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "db";
global $country;
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "select emr_value from countries where country_name='$country'";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()) {
$emr_value = $row["emr_value"];
echo "<h1>EMR : " . $emr_value . "</h1>";
}
$conn->close();
?>
Maybe you should have only one code:
<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "db";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT meta_value FROM wp_usermeta WHERE user_id='$user_id' AND meta_key='custom_field_6'";
$result1 = $conn->query($sql);
if ($result1->num_rows > 0) {
// output data of each row
while ($row1 = $result1->fetch_assoc()) {
$country = trim($row1["meta_value"]);
$sql = "SELECT emr_value FROM countries WHERE country_name='$country'";
$result2 = $conn->query($sql);
while ($row2 = $result2->fetch_assoc()) {
echo "<h1>EMR : " . $row2["emr_value"] . "</h1>";
}
}
} else {
echo "0 results";
}
$conn->close();
?>
Or create two functions in one code: one that returns $country and one that returns emr_value.
