Catchable fatal error

Smudly · April 26, 2011

I'm creating a Contact Us page that has a form users may use to send a message.

I've run into an issue and I have never seen this error before. Could anyone help explain how to fix this please?

Catchable fatal error: Object of class stdClass could not be converted to string in /homepages/30/d354929366/htdocs/contact.php on line 13

Line 13 is:

$contactsql = "SELECT * FROM users WHERE username='$username'";

<?php
include("inc/config.php");
include_once("inc/functions.php");

$ip = $_SERVER['REMOTE_ADDR'];

$username = $_SESSION['customer'];
$submit = (isset($_POST['submit']));
$to = "myemail@gmail.com";
$subject = "New Contact!";

        $contactsql = "SELECT * FROM users WHERE username='$username'";

$result = mysql_query($contactsql);
$row = mysql_fetch_assoc($result);

$userid = $row['userid'];
$name = $row['name']; 
$email = $row['email'];
$username = $row['username'];

if($submit){

if(!isset($_SESSION['customer'])){

$getusername = mysql_query("SELECT username FROM users WHERE email='$email'");
$getrow = mysql_fetch_assoc($getusername);

$username = $getrow['username'];
}


$answered = 0;
$date = date("Y-m-d");
$name = mysql_safe($_POST["name"]);
$email = mysql_safe($_POST["email"]);
$message = mysql_safe($_POST["comments"]);

$_SESSION['customer'] must be an instance of a class or an object.

Are you trying to access a method or a property of that class to get the username?

Smudly · April 26, 2011

Honestly I'm not sure. I had a pro setup the member's system and it's over my head. He has a bunch of Classes that take care of this stuff, so I'm unsure how I'm supposed to use it.

Add the following code right before the $username = $_SESSION['customer']; line to find out what $_SESSION['customer'] contains -

echo "<pre>";
var_dump($_SESSION['customer']);
echo "</pre>";

You can access the username property using either -

$_SESSION['customer']->username

or after you assign $username = $_SESSION['customer']; using -

$username->username

However, I suspect that $_SESSION['customer'] is supposed to be an instance of a customer class, had the class definition existed before the session_start() statement.

You need to find where $_SESSION['customer'] was created and at a minimum the person who wrote this code should have given you a list of the classes and the definition of the properties and methods of each class.

That did it. Thanks for the rundown on it all. It helps a lot.

I found that the session was created in the Customer class (customer.php)

function reload_session($cod) 
{    	
        $rowCutomer=  $this->mPer->getOne($cod);
	$_SESSION['customer'] = mysql_fetch_object($rowCutomer);
    }
