Question

i am actually started using PDO , i have seen many questions on PDO but i am not able resolve my problem by reading those questions.

I have one file PDO Config File called db.php , this file having no problem.

db.php 

<?php 
######## PDO Config File ##########
        $mysql_hostname = "localhost";
        $mysql_user = "web";
        $mysql_password = "123123";
        $mysql_database = "123123";
        //$odb = new PDO ("mysql:host=".$mysql_hostname.";dbname=".$mysql_database;charset:UTF-8",$mysql_user,$mysql_password);
        try{
                $connect = new PDO("mysql:host=".$mysql_hostname.";dbname=".$mysql_database.";charset:UTF-8", $mysql_user, $mysql_password, array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));
        }
        catch(PDOException $pe){
            die('Could connect to the database because: ' .$pe->getMessage());
        }
 ?>

I have Included this file in to the following PHP file[setting.php] .

setting.php

class Account
{
    public function userEmailChnage($inputCurrentEmail,$inputChangeEmail,$inputConfirmEmail)
    {
        if(!empty($inputCurrentEmail) AND !empty($inputChangeEmail) AND !empty($inputConfirmEmail)){
            $selectEmail        = "select mail from users where mail = ?";
            $selectEmailPrepare = $connect -> prepare($selectEmail);
            $selectEmailPrepare -> execute(array($inputConfirmEmail));

        if ($selectEmailPrepare ->rowCoun() > 0 ) {     
                if($inputChangeEmail == $inputConfirmEmail) {
                        $EmailUpdate = "UPDATE users SET mail= ?";
                        $EmailUpdatePrepare = $connect->prepare($EmailUpdate);
                        $EmailUpdatePrepare -> execute(array($inputChangeEmail));
                        $msg[EmailUpdateOpration]=Success;

                }else{
                        $msg[IsConfirmMailMatching]=FALSE; //---------------- > JSON ERROR Msg 
                }
            }else{
                    $msg[IsEmailInDatabase]=FALSE; //---------------- > JSON ERROR Msg 
            }
        }else{
            $msg[IsEmailFieldEmpty]=TRUE; //---------------- > JSON ERROR Msg 
        }   
        header("Content-Type: application/json", true); 
        echo json_encode($msg); 
    }

}

After the execution of the file i am facing following error :

Fatal error: Call to a member function prepare() on a non-object in /home/admin/public_html/class/setting.php on line 12

I am tried to change PDO config file , it didn’t worked. I started testing setting.php .. Not able to solve it !

Answer 1

In this line:

$EmailUpdatePrepare = $connect->prepare($EmailUpdate);

… you get this error:

Call to a member function prepare() on a non-object

That means exactly that: $connect is not an object. It appears to be a global variable so you need to handle it as such: either call global $connect; before you use it or read it through $GLOBALS['connect']. (Or, even better, pass it as argument to the method.)
