1. 創(chuàng)建author管理頁面

? 主要包含以下幾個頁面:

? A. index.php, 準(zhǔn)備各種變量數(shù)據(jù).供展示頁面使用.

? B. authors.html.php, 顯示author.

? C. form.html.php, 用于編緝或添加作者的頁面.

頁面郊果:

2. author頁面的主要流程

2.1 是否已登錄

if (!user_is_login()){include '../login.html.php';exit();}

2.2 是否有權(quán)限

if (!user_has_role('Content Editor')){$error = 'only Content Editor may access this page...';include '../access.denied.html.php';exit();}

2.3 添加作者

// add authorsif (isset($_GET['add'])) {include $_SERVER['DOCUMENT_ROOT'].'/PHP_MySQL_Web/includes/db.inc.php';$pageTitle = 'Add author';$action = 'addForm';$author_name = '';$author_email = '';$id = '';$author_password = '';$button = 'Add author';try { $result = $pdo->query('SELECT id, description FROM role');foreach ($result as $row){$roles[] = array('id'=>$row['id'],'description'=>$row['description'],'selected'=>false);}} catch (PDOException $e) {$error = 'Error getting list of jokes to edit...'.$e->getMessage();include $_SERVER['DOCUMENT_ROOT'].'/PHP_MySQL_Web/includes/error.html.php';exit();} include 'form.html.php';exit();}// add authorsif (isset($_GET['addForm']) && $_POST['author_name'] != '') {include $_SERVER['DOCUMENT_ROOT'].'/PHP_MySQL_Web/includes/db.inc.php';// add authortry {$sql = 'INSERT INTO author(name,email) VALUES(:name,:email);';$s = $pdo->prepare($sql); $s->bindValue(':name', $_POST['author_name']);$s->bindValue(':email', $_POST['author_email']); $s->execute();} catch (PDOException $e) {$error = 'Error adding author...'.$e->getMessage();include $_SERVER['DOCUMENT_ROOT'].'/PHP_MySQL_Web/includes/error.html.php';exit();}$authorid = $pdo->lastInsertId();// add passwordif ($_POST['author_password'] != ''){ try {$sql = 'UPDATE author SET password = :password where id = :authorid;';$s = $pdo->prepare($sql);$password = get_md5_password($_POST['author_password']);$s->bindValue(':password', $password); $s->bindValue(':authorid', $authorid); $s->execute(); } catch (PDOException $e) {$error = 'Error updating password...'.$e->getMessage();include $_SERVER['DOCUMENT_ROOT'].'/PHP_MySQL_Web/includes/error.html.php';exit();} }// insert rolesif (isset($_POST['roles'])){foreach ($_POST['roles'] as $role){try {$role_role .= $role;$sql = 'INSERT INTO authorrole(authorid, roleid) VALUES (:authorid,:roleid);';$s = $pdo->prepare($sql);$s->bindValue(':authorid', $authorid);$s->bindValue(':roleid', $role);$s->execute();} catch (PDOException $e) {$error = 'Error insertting role...'.$e->getMessage();include $_SERVER['DOCUMENT_ROOT'].'/PHP_MySQL_Web/includes/error.html.php';exit();}}}header('Location: .');exit();}

2.4 編輯作者

2.6 刪除作者

2.7 顯示作者列表

// select all authors.try {include $_SERVER['DOCUMENT_ROOT'].'/PHP_MySQL_Web/includes/db.inc.php';$querySql = "SELECT id, name, email FROM author;";$result = $pdo->query($querySql); foreach ($result as $row) {$authors[] = array('id'=>$row['id'], 'name'=>$row['name'], 'email'=>$row['email']); } if (count($authors) > 0) {$sql = "SELECT table_rows AS RCT FROM information_schema.tables WHERE table_name = 'author';";$s = $pdo->prepare($sql);$s->execute();$row = $s->fetch();$rowCount = $row['RCT'];include $_SERVER['DOCUMENT_ROOT'].'/PHP_MySQL_Web/admin/authors/authors.html.php';} else {} } catch (PDOException $e) {$error = "query author failed...".$e->getMessage();include $_SERVER['DOCUMENT_ROOT'].'/PHP_MySQL_Web/includes/error.html.php';exit();}
