Помогите разобрать код на косточки. (Можно просто пояснить, что каждая строка в этом коде означает, что-бы понять как это работает). И помочь исправить !
if(isset($_GET['edit_id']) && !empty($_GET['edit_id']))
{
$id = $_GET['edit_id'];
$stmt_edit = $DB_con->prepare('SELECT name, name_ru, description, description_ru, price, image FROM colianuri WHERE ID =:uid');
$stmt_edit->execute(array(':uid'=>$id));
$edit_row = $stmt_edit->fetch(PDO::FETCH_ASSOC);
extract($edit_row);
}
else
{
header("Location: admin.php");
}
Вылазит вот такая ошибка:
Warning: extract() expects parameter 1 to be array, boolean given in C:\xampp\htdocs\sam2\editform.php on line 13
Переменная
$edit_row приходит BoolenFalse, хотя в ней должен содержаться массив. Что не так? Всё работало, и в один момент перестало.
Вот исходник edit.php:
<?php
error_reporting( ~E_NOTICE );
require_once 'dbconfig.php';
if(isset($_GET['edit_id']) && !empty($_GET['edit_id']))
{
$id = $_GET['edit_id'];
$stmt_edit = $DB_con->prepare('SELECT name, name_ru, description, description_ru, price, image FROM colianuri WHERE ID =:uid');
$stmt_edit->execute(array(':uid'=>$id));
$edit_row = $stmt_edit->fetch(PDO::FETCH_ASSOC);
extract($edit_row);
}
else
{
header("Location: admin.php");
}
if(isset($_POST['btn_save_updates']))
{
$name = $_POST['name'];// name
$name_ru = $_POST['name_ru'];// name
$description = $_POST['description'];// description
$description_ru = $_POST['description_ru'];// description
$price = $_POST['price'];
$imgFile = $_FILES['image']['name'];
$tmp_dir = $_FILES['image']['tmp_name'];
$imgSize = $_FILES['image']['size'];
if($imgFile)
{
$upload_dir = 'image/'; // upload directory
$imgExt = strtolower(pathinfo($imgFile,PATHINFO_EXTENSION)); // get image extension
$valid_extensions = array('jpeg', 'jpg', 'png', 'gif'); // valid extensions
$image = rand(1000,1000000).".".$imgExt;
if(in_array($imgExt, $valid_extensions))
{
if($imgSize < 5000000)
{
unlink($upload_dir.$edit_row['image']);
move_uploaded_file($tmp_dir,$upload_dir.$image);
}
else
{
$errMSG = "Sorry, your file is too large it should be less then 5MB";
}
}
else
{
$errMSG = "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
}
}
else
{
// if no image selected the old image remain as it is.
$userpic = $edit_row['image']; // old image from database
}
// if no error occured, continue ....
if(!isset($errMSG))
