我的用于插入数据的PHP代码：

<?php
//create connection
$con=mysqli_connect("localhost","root","","carzpedia");

//check connection
if(mysqli_connect_errno())
{
    echo"Failed to connect to MySQL:".mysqli_connect_errno();
}

//get data from form
$name=$_POST['name'];
$eadd=$_POST['eadd'];
$subject=$_POST['subject'];
$description=$_POST['description'];
$date=date('Y-m-d h:i:sa');

//submit data
$sql="INSERT INTO 'contact us' (name,eadd,subject,description,date)
VALUES ('$name','$eadd','$subject','$description','$date')";
if(mysqli_query($con,$sql))
{
    echo "Data submitted successfully";
}
else
{
echo"Error submitting data:".mysqli_error($con);
}

//close connection
mysqli_close($con);
?>

错误： 提交数据时出错：您的SQL语法有错误;查看与您的MySQL服务器版本相对应的手册，以便在“联系我们”（姓名，eadd，主题，描述，日期）附近使用正确的语法VALUES（'Sahil Sunny'，'sahils'在第1行

Answer 1

您需要在表格上使用反引号而不是引号。标识符引号字符是反引号。

INSERT INTO `contact us` (name,eadd,subject,description,date)
            ^          ^ backticks not quotes (')
VALUES ('$name','$eadd','$subject','$description','$date')

旁注：我建议你使用mysqli，利用预准备语句来执行更安全的查询。

Answer 2

使用“联系我们”而不是“联系我们”＃39;

还有一件事是避免表名中的空格。
