我在这段代码中的目标是为用户创建稍后应用部分,我创建了一个隐藏按钮来获取确切帖子的 id,我正在获取 id,但是当我绑定并执行时,我收到了这个警告,我检查了几个其他人的问题与我的类似,但他们似乎并没有解决我的确切问题。我到底要绑定什么来获取具有该特定 ID 的帖子的信息
这是函数:
public function Index(){
if(isset($_POST['submit'])){
$id = $_POST['applylater_id'];// I got this from a button the user is to click
// INSERT INTO MYSQL
$this->query('INSERT INTO apply_later(id, title, body, link, user_id, user_name) SELECT id, title, body, link, user_id, user_name FROM shares WHERE id = :id');
$this->bind(':title', 'title');
$this->bind(':body', 'body');
$this->bind(':link', 'link');
$this->bind(':user_id', 1);
$this->bind(':user_name', 'user_name');
$this->bind(':id', $id);
$this->execute();
//Verify
if($this->lastInsertId()){
//Redireect
Messages::setMsg('Successfully Added to your apply Later section', 'successMsg');
header( "refresh:2; url=http://localhost/phpsandbox/phptutorials/website2/shares/applylater" );
}
}
//
$this->query('SELECT * FROM shares ORDER by id desc ');
$rows = $this->resultSet();
return $rows;
}
//这是我在上面调用的绑定和执行函数
public function query($query){
$this->stmt = $this->dbh->prepare($query);
}
public function bind ($param, $value, $type =null) {
if(is_null($type)){
switch(true) {
case is_int($value):
$type = PDO::PARAM_INT;
break;
case is_bool($value):
$type = PDO::PARAM_BOOL;
break;
case is_null($value):
$type = PDO::PARAM_NULL;
break;
default:
$type = PDO::PARAM_STR;
}
}
$this->stmt->bindValue($param, $value, $type);
}
public function execute(){
return $this->stmt->execute();
}
现在这是我使用的主要形式,但它可以获取 id 但不会在屏幕上显示
<?php foreach ($viewmodel as $item) : ?>
<div class="well">
<div class="text-center">
<img src="http://localhost/phpsandbox/phptutorials/website2/assets/image/job.png" class="img-circle" alt="Cinque Terre" width="50" height="50">
<h3> <?php echo $item['title']; ?></h3>
<small> Username: <?php echo $item['user_name']; ?></small>
<br />
<small><?php echo $item['create_date']; ?></small>
</div>
<hr />
<p><?php echo $item['body']; ?></p>
<br />
<div class="text-center">
<a href="<?php echo $item['link']; ?>" target="_blank" class="btn btn-info">Apply Now</a>
<br />
</div>
<hr />
<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>" >
// 当你点击提交时,我想获取这个确切帖子的 id 并将数据发送到不同的表中,这样我就可以在不同的页面中显示这个确切的帖子。
<input type="hidden" name="applylater_id" value="<?php echo $item['id']; ?>">
<input class="btn btn-primary" type="submit" name="submit" value="Apply Later">
</form>
这是我的桌子
