在布尔值上调用成员函数 execute() [英] Call to a member function execute() on boolean in
本文介绍了在布尔值上调用成员函数 execute()的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我的html:
我的rent.php文件:
connect_error){死($conn->connect_error);}$query = "SET NAMES utf8";$result = $conn->query($query);如果(!$结果){死($conn->错误);}$req = $conn->prepare('INSET INTO renter (email, msg_text) VALUES(?, ?)');$req->execute(array($_POST['email'], $_POST['msg_text']));header('位置:menu.php');
我尝试提交时的错误是:致命错误:调用成员函数 execute() on boolean in C:...\rent.php on line 18
email、msg_text 为 varchar 类型
解决方案
mysqli->prepare
也可以返回FALSE
(检查http://php.net/manual/en/mysqli.prepare.php) 如果发生错误.你的问题是你有 INSET
而不是 INSERT
.
My html :
<form action="rent.php" method="post"><pre>
Email : <input type="text" name="email">
Message : <input type="text" name="msg_text">
<input type="submit" value="Rent it">
</pre></form>
My rent.php file :
<?php
require_once 'login.php';
$conn = new mysqli($hn, $un, $pw, $db);
if ($conn->connect_error) {
die($conn->connect_error);
}
$query = "SET NAMES utf8";
$result = $conn->query($query);
if (!$result) {
die($conn->error);
}
$req = $conn->prepare('INSET INTO renter (email, msg_text) VALUES(?, ?)');
$req->execute(array($_POST['email'], $_POST['msg_text']));
header('Location: menu.php');
My error when I try to submit, is : Fatal error: Call to a member function execute() on boolean in C:...\rent.php on line 18
email, msg_text are in varchar type
解决方案
mysqli->prepare
can also return FALSE
(check http://php.net/manual/en/mysqli.prepare.php) if an error occurred. Your problem is that you have INSET
instead of INSERT
.
