我正在尝试使用相同的视图来创建和更新条目，创建工作正常，但是当我尝试更新时，出现此SQL语法错误，但在模型中看不到语法错误
致命错误：未被捕获的PDOException：SQLSTATE [42000]：语法错误或访问冲突：1064您的SQL语法有错误；请参阅附录A。请检查与您的MySQL服务器版本相对应的手册，以获取正确的语法，以在“ TABLE article SET SET title ='ewe'，text ='ew'，category_id ='1'的情况下在第1行使用id ='1'']
<?php
use App\Model\ArticleModel;
if(isset($article)) {
$id = $article['id'];
$title = $article['title'];
$text = $article['text'];
$category_id = $article['category_id'];
$action = "?page=form&id=$id";
}
if (!empty($_POST)) {
$id = $_GET['id'];
$title = $_POST['title'];
$text = $_POST['text'];
$category_id = $_POST['category_id'];
if(isset($_GET['id'])) {
$this->modelName->update($id,$title, $text, $category_id);
// $this->modelName is actually correct, it is defined in the core
} else {
$this->modelName->create($title, $text, $category_id);

public function create($title, $text, $category_id) {
return $this->db->save(
'INSERT INTO articles SET title = ?, text = ?, category_id = ?', [$title, $text, $category_id]
);
}
public function update($id, $title, $text, $category_id) {
return $this->db->save(
"UPDATE TABLE articles SET title = ?, text = ?, category_id = ? WHERE id = ?", [$title, $text, $category_id, $id]
);
}
我怀疑错误来自$ action和$ _GET ['id']，但我找不到解决方法
在您的更新功能中。这是无效的SQL语法UPDATE TABLE articles ...。它应显示为UPDATE articles ...
