So I wanted to install an acp on my homepage. I uploaded all needed files on my webserver (I use FileZilla Client) and opened phpMyAdmin with xampp.
It connects the database but then it says
"Database does not exist."
I'm fairly new to working with phpMyAdmin and mySQL as well.
this is what my db.php looks like:
<?php
$host = "localhost"; // database server
$user = "akichuchan"; // db username
$pw = "cherryjuice"; // db password
$db = "acp"; // db name
$link = mysql_connect($host, $user, $pw, $db) or die ("No connection possible.");
mysql_select_db($db, $link) or die ("Database does not exist.");
?>
What did I do wrong?
Thanks in advance. :)
Try the below working code:
<?php
$host = "localhost"; // database server
$user = "akichuchan"; // db username
$pw = "cherryjuice"; // db password
$db = "acp"; // db name
$link = mysql_connect($host, $user, $pw) or die ("No connection possible.");
mysql_select_db($db, $link) or die ("Database does not exist.");
?>
NOTE: Don't use " mysql_ ". Better to use " PDO or Mysqli_ " ( safe and secure ) .

In my script I link to a page that connects to my database :
include "connect.php";
connect.php
<?php
error_reporting(E_ERROR);
/* Allows PHP to connect to your database */
// Database Variables
$Host = "myhost";
$User = "username";
$Password = "password";
$DBName = "database";
// Connect to Database
$connect = mysql_connect($Host, $User, $Password)
or die ("Could not connect to server ... \n" . mysql_error ());
mysql_select_db($DBName)
or die ("Could not connect to database ... \n" . mysql_error ());
?
Then in another script I have an insert query:
include "connect.php";
$Link = mysql_connect($Host, $User, $Password);
$Query = "INSERT INTO mytable VALUES ('0','".mysql_escape_string($forename)."','".mysql_escape_string($surname)."', '".mysql_escape_string($username)."', '".mysql_escape_string($password)."', '".mysql_escape_string($email)."')";
if(mysql_db_query ($DBName, $Query, $Link)) {
$message = "You have successfully registered";
header("Location: register.php?message=".urlencode($message));
} else {
die("Query was: $Query. Error: ".mysql_error($Link));
}
}
}
Why is this necessary :
$Link = mysql_connect($Host, $User, $Password);
Hasn't the connection already been established?
There is no point in doing this, especially as mysql_* functions will assume the last opened connection if none is given.
However, even with two calls to mysql_connect, only one connection is made. From the docs:
If a second call is made to mysql_connect() with the same arguments, no new link will be established, but instead, the link identifier of the already opened link will be returned. The new_link parameter modifies this behavior and makes mysql_connect() always open a new link, even if mysql_connect() was called before with the same parameters.
So by default, the existing connection will be returned.
i'm new here and doing some project,
how can i connect to my database in db4free.net from php,
i have tried this
<?php
$host = "db4free.net/mainbookstore";
$user = "***";
$pass = "****";
$database = "mainbookstore";
$conn = mysql_connect($host, $user, $pass);
if ($conn) {
$buka = mysql_select_db ($database);
if (!$buka) {
die ("Database tidak dapat dibuka");
}
} else {
die ("Server MySQL tidak terhubung");
}
?>
but get error Such no host, but in my java use :
dataSource.setUrl("jdbc:mysql://db4free.net:3306/mainbookstore");
i can connect to my database.
Thanks before :)
Most likely, it is the missing port. Try
$host = "db4free.net:3306/mainbookstore";
and it should work.
Keep getting same error message
(Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /home/content/00/7882800/html/Connections/dueslogin.php on line 27
Unable to connect to database! Please try again later.)
<?php
//Variables for connecting to your database.
//These variable values come from your hosting account.
$hostname = "TarHeelsDues.db.7882800.hostedresource.com";
$username = "TarHeelsDues";
$dbname = "TarHeelsDues";
//These variable values need to be changed by you before deploying
$password = "************";
$usertable = "DuesLogin";
$yourfield = "your_field";
//Connecting to your database
mysql_connect($hostname, $dbname, $password) OR DIE ("Unable to
connect to database! Please try again later.");
mysql_select_db($TarHeelsDues);
//Fetching from your database table.
$query = "SELECT * FROM $usertable";
$result = mysql_query($query);
if ($result) {
while($row = mysql_fetch_array($result)) {
$name = $row["$yourfield"];
echo "Name: $name<br>";
}
}
?>
change the mysql_connect line to
mysql_connect($hostname, $username, $password) OR DIE ("Unable to
connect to database! Please try again later.");
mysql_select_db($dbname);
A little mistake on there, you have to use $username not $dbname in mysql_connect.
mysql_connect($hostname, $username , $password) OR DIE ("Unable to
connect to database! Please try again later.");
mysql_select_db($TarHeelsDues);
The correct syntax should be like this:-
mysql_connect($hostname, $username , $password) OR die ("Unable to connect with the server");
mysql_select_db($TarHeelsDues) or die('Cannot connect with the database!');
I am just using a basic code to connect to my Mysql database. I am able to connect to my server but not database. using sqlyog:
<?php
$username = "root";
$hostname = "localhost";
$dbhandle = mysql_connect($hostname, $username) or die("Unable to connect to MySQL");
$selected = mysql_select_db("project",$dbhandle) or die("Could not select project");
$sql = "SELECT image_small FROM images";
mysql_query($sql,$selected);
while($row=extract_row($sql))
{
echo $row['image_small'];
}
?>
where is password of database? mysql_connect should be used as:
mysql_connect("localhost", "mysql_user", "mysql_password");
otherwise it will be the default password that will be used
There are so many things wrong here.
1. Your have a blank password for the root user in your database.
2. You're using mysql_* which everybody know is subject to many hasck.
3. You're trying to "extract" a row from your SQL query.
Use PDO:
$DB = new PDO("mysql:host=localhost;dbname=project","root","root_password");
$sql = "SELECT image_small FROM images";
foreach($DB->query($sql, PDO::FETCH_ASSOC) as $row) {
echo $row['image_small'];
}
try to connect using the following statement
$selected = mysql_select_db("project");
// i think you have to provide password in here mysql_connect($hostname, $username,$password);
since it is localhost and user is root you could use like this
mysql_connect($hostname, $username,"");
I already have the mysql database made, I just need to connect php to mysql locally but I don't know the php commands for that.
cheers
$server = 'localhost';
$user = 'myUser';
$pass = 'myPass';
$dbname = 'MyDatabase';
$con = mysql_connect($server, $user, $pass) or die("Can't connect");
mysql_select_db($dbname);
The following contains a pretty good example: http://ca3.php.net/manual/en/mysql.examples-basic.php
This is a simple connect to the mysql server. After Connecting to the server it selects a DB
<?php
mysql_connect("localhost", "admin", "1admin") or die(mysql_error());
echo "Connected to MySQL<br />";
mysql_select_db("test") or die(mysql_error());
echo "Connected to Database";
?>
