Question

这给了我一个'无效语法'错误。什么是无效的？

$companyName = 'big company';
$address1 = 'big bay #8';
$address2 = 'some big warehouse';
$city = 'big city';
$province = 'AB';
$postalCode = 'T1T0N0';
$phone = '0123456789';
$email2 = 'bigKahuna@bigKahuna.edu';

$query = "INSERT INTO clients ";
$query .= "(companyName, address1, address2, city, province, postalCode, phone, email) ";
$query .= "VALUES (". $companyName.",".$address1.",".$address2.",".$city.",".$postalCode.",".$phone.",".$email2.")";

print ($query . "<br><br>");

$result = mysql_query($query, $connexion);

if ($result)
{
    //  Success!
    echo "Fabulous!  check the DB, we did it! :D<br>";
} else {
    //  Fail!
    echo"CRAAAAAPP!  something went wrong.  FIX IT!  :P<br>";
    echo mysql_error();
}

我已经对表格进行了三次检查，它基本上都是VARCHAR（50），名称正确且序列正确（不是错误的序列会破坏它......）。

我错过了什么？ ......并且不，连接没有错误拼写......

Answer 1

你有一堆字符串变量应该用单引号括起来（并正确转义）。

query = "INSERT INTO clients ";
$query .= "(companyName, address1, address2, city, province, postalCode, phone, email) ";
$companyName = mysql_real_escape_string($company_name);
//... etc - escape all other variables 
$query .= "VALUES ('". $companyName."',"'.$address1."','".$address2."','".$city."','".$postalCode."','".$phone."','".$email2."')";

Answer 2

您正在插入文字而不是用单引号包围文本。强烈建议您更改为使用参数化查询。
