mysql - PHP Fatal error: Call to a member function fetchAll() on a non-object in pdo login -


i've been working on web app client, , came across error when building database login code.

the config.php code

php try {     // create connection     $dbh = new pdo("mysql:host=" . $localhost . ";dbname=" . $database, $username, $dbpassword); } catch (pdoexception $e) {     // echo error message if connection fails     echo 'connection failed: ' . $e->getmessage();     exit; }

and login.php code

require 'config.php'; $sql = "select * `users` `email` = ?"; $stmt = $dbh->prepare($sql); $result = $stmt->execute([$_post['email']]); $users = $result->fetchall();  if (isset($users[0])) {     if (password_verify($_post['password'], $users[0]->password)) {         // valid login         include 'dashboard.php';     }      else {         // invalid password         echo "<p class=''>the password entered incorrect. please try again.</p>";     } }  else {     // invalid email     echo "<p class=''>we're sorry, email not in our records. please check spelling , try again.</p>"; }

the register.php works, , adds fields database, i'll add make sure i'm not missing something, since trying access database verify record.

require 'config.php'; require 'lib/password.php';  $company = $_post["company"]; $email = $_post["email"]; $password = $_post["password"]; $hash = password_hash($password, password_bcrypt);  $stmt = $dbh->prepare("insert users(id,company,email,password) values (?,?,?,?)"); $stmt->execute([$id, $company, $email, $hash]);

you using wrong object($result) fetch

you need use $stmt this

$users = $stmt->fetchall();

also, need pass variable array before that

$stmt->execute(array($_post['email']));

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
