My sql query is not executing on server with use session? - php

Question

I have found record from login table but my mysql query is now executing.
following is my code.
$sqlQuery = "SELECT * FROM ".$table."
WHERE mobile_number='".$mobile_number."' AND
password='".base64_encode($password)."'";
// End
$select = mysql_query($sqlQuery);
$result = mysql_num_rows($select);
echo "<pre>Rest";
print_r($result);
It's always return 0 but same query is working in Phpmyadmin dashboard.
When i used mysql_error() function with mysql_query like following
$select = mysql_query($sqlQuery) or die ('Error updating database: '.mysql_error());
It's given error : Access denied for user ''#'localhost' (using password: NO)
Following is my connection code..
$dbname = "######";
$host = "localhost";
$user = "#####";
$password = "#####";
$connection = mysql_connect($host,$user,$password) or die("Error in database connection.");
if (!$connection)
{
return false;
}
if(!mysql_select_db($dbname, $connection))
{
return false;
}
I don't know why i faced the problem if anyone have idea about this pleas help me on this.
Thank You!!

Answer 1

Guess you gotta connect to your SQL Server with username and password. Error message says you didn’t even pass a username.
Simple example:
$link = mysql_connect('example.com:3307', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
…
// do your stuff here
Please be sure to – at least – secure your parameters be escaping them with mysql_real_escape_string() for instance:
http://php.net/manual/en/function.mysql-real-escape-string.php
Or, even better, use PDO:
$stmt = $pdo->prepare('SELECT * FROM your_table WHERE mobile_number = :mobile_number');
$stmt->execute(array('mobile_number' => $mobile_number));

You should check the host, user name, and password in the configuration file and make sure that the information is consistent with the information given by the MySQL server administrator.
Reset the password and try it out:
Enter set password for 'root'#'localhost'=password(' your password ');Then restart the mysql service.Enter mysql-u root-p
