我有这个代码来保存文本区域的笔记
这是我的 post-note.php 文件
<?php
include('connect.php');
if(isset($_POST['note_title'])){
$note_title = $_POST['note_title'];
$note_description = $_POST['note_description'];
$login_user_id = $_SESSION['user_id'];
$errors = array();
if($note_title == ""){
$errors['note_title'] = 'fine';
}else{
$errors['note_title'] = 'fine';
}
if($note_description == ""){
$errors['note_description'] = '<span class="note_description">Please enter something</span>';
}elseif(strlen($note_description) < "3"){
$errors['note_description'] = '<span class="note_description">your note is too short</span>';
}else{
$errors['note_description'] = 'fine';
}
if($errors['note_title'] && $errors['note_description'] == 'fine'){
$Query = "INSERT INTO notes (note_title, login_user_id, note_description, is_private)
VALUE('$note_title', '".$login_user_id."', '".$note_description."','0')";
if (!mysql_query($Query)){
die('Error: ' . mysql_error());
}
$errors['done'] = 'done';
unset($_POST['note_title']);
unset($_POST['note_description']);
}
}
echo json_encode($errors);die;
?>`
我想第一次插入新行然后想更新数据库中的那一行
