使用PDO插入数据库 [英] Inserting into database using a PDO

问题描述

我正在尝试将数据插入服务器上的数据库中.

I'm trying to insert data into a database that I have on my server.

要连接到我的数据库，我需要以下代码:

To connect to my database I have the following code:

<?php
$host = "/homes/49/jc192699/public_html/dbase/";
$database = "EduPro.db";
$dbhandle = new PDO("sqlite:".$host.$database);

try {
    $dbhandle = new PDO("sqlite:".$host.$database);

} catch (PDOException $e) {

echo 'Connection failed: ' . $e->getMessage();
}
?> 

一切正常！我已经将其包含在我的代码中，所以这不是问题.

and this all works fine! I have included this into my code so that is not the issue.

这是我用于将数据插入数据库的代码:

Here is my code for inserting data into the database:

<?php

$sql = "INSERT INTO USERS (`userName`, `password`) VALUES (`test, `testy`)";
  if ( $fetched = $dbhandle->query($sql)){
  $fetched->execute(PDO::FETCH_BOTH);
  echo "Success!";
  }

  else {
echo "Fail.";
}

?>

由于某种原因，它没有将数据插入数据库.我知道SQL语句是100％正确的，因为我已经在其他地方对其进行了测试.

It is not inserting the data into the database for some reason. I know that the SQL statement is 100% correct as I have tested it elsewhere.

有人可以帮助我吗?

推荐答案

您正在打开两个数据库连接.将您的代码更改为

you are opening two database connection. change your code to

$host = "/homes/49/jc192699/public_html/dbase/";
$database = "EduPro.db";
try {
    $conn = new PDO("sqlite:".$host.$database);
} catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage();
}

您不应在查询中使用反引号，而应使用单引号.并且该列也不应使用任何引号.

you should not use backquote instead using single quote in your query. and also column should not have any quotes.

try {
    $sql = "INSERT INTO USERS (userName, password) VALUES ('test', 'testy')";
    $sth = $conn->query($sql);
} catch(PDOException $e) {
    echo $e->getMessage();
}

要获取使用此记录所需的记录

to fetch the records you need to use this

try {
    $sth = $conn->query('SELECT * FROM USERS');
    $rows = $sth->fetchAll(PDO::FETCH_ASSOC);
    //$rows contains the fetched records in an associative array
    var_dump($rows);
} catch(PDOException $e) {
    echo $e->getMessage();
}
