Problem now:
My Update Query is not working completly, the E-Mail query work but the status query is not working.
PHP CODE

$s_mail = $_POST['email'];
$row = mysql_num_rows(mysql_query("SELECT email FROM users WHERE email='$s_mail'"));

}
//PROBLEM starts here
if(!empty($_POST['status'])) {
$query .= ",`status`='".$_POST['status']."'";
$_SESSION['u']['status'] = $_POST['status'];
}
//AND ends here
$query .= " WHERE id='".$_SESSION['u']['id']."'";
mysql_query($query);
header("Location: ".$l['settings']."?msg=1");
die("REDIRECT");
}
HTML FORM
<input maxlength="200" type="text" class="form-control" placeholder="Status" name="status" value="<?php //ECHO STATUS ?>" />
Maybe someone can help me.

Answer 1

On your $query you have
$query .= ",`status`='".$_POST['status']."'";
remove comma make it like this
$query .= " `status`='".$_POST['status']."'";

Answer 2

You need to set a flag for email condition as
$flag = FALSE;// set a flag
if (!empty($_POST)) {
if (!empty($_POST['email']) && filter_var($_POST['email'], FILTER_VALIDATE_EMAIL) && $_POST['email'] != $_SESSION['u']['email']) {
$s_mail = $_POST['email'];
$row = mysql_num_rows(mysql_query("SELECT email FROM users WHERE email='$s_mail'"));
if ($row != 0) {
header("Location: " . $l['settings'] . "?msg=2");
die("REDIRECT");
}
$flag = TRUE;// set to true if success
$_SESSION['u']['email'] = $_POST['email'];
} else if (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
header("Location: " . $l['settings'] . "?msg=3");
die("REDIRECT");
}
//PROBLEM starts here
if (!empty($_POST['status'])) {
$query = "UPDATE users SET";
$query .= " `status`='" . $_POST['status'] . "'";
if ($flag) {// if true then apply email condition
$query .= ",`email`='" . $_POST['email'] . "'";
}
$query .= " WHERE id='" . $_SESSION['u']['id'] . "'";
$_SESSION['u']['status'] = $_POST['status'];
}
//AND ends here
mysql_query($query);
header("Location: " . $l['settings'] . "?msg=1");
die("REDIRECT");
}
Note:- mysql is deprecated instead use mysqli OR pdo
