Mysql PHP Error - Login Validation -


good day gents

busy frustrating myself here. busy trying write simple login script validates login against database.

however keep on getting:

warning: mysql_fetch_array() expects parameter 1 resource, boolean given in

here code.... when run query on sql workbench works 100%

<?php  // grab user submitted information $email = $_post['users_email']; $pass = $_post['users_pass'];  // connect database $con = mysql_connect('localhost','root',''); // make sure connected succesfully if(! $con) {     die('connection failed'.mysql_error()); }  // select database use mysql_select_db('arctecs',$con);  $result = mysql_query('select users_email, users_pass users users_email = $email');  $row = mysql_fetch_array($result);  if($row['users_email']==$email && $row['users_pass']==$pass)     echo'you validated user.'; else     echo'sorry, credentials not valid, please try again.'; ?>

this not correct 

'select users_email, users_pass users users_email = $email'

better way 

"select users_email, users_pass users users_email = '$email'"

need wrap string data in single quote.

the post data directly being used in query not good. start using pdo prepared statements avoid sql injections or at-least sanitize data as

$email = $_post['users_email']; $pass = $_post['users_pass']; $con = mysql_connect('localhost','root',''); // make sure connected succesfully if(! $con) {     die('connection failed'.mysql_error()); }  $email = mysql_real_escape_string($email);
