php - 错误插入

Question

PHP 代码

<?php
$imageId = $_GET ["a"];
$likerId = $_GET ["b"];

// connection to the database
$dbhandle = mysql_connect ( "localhost", "root", "" ) or die ( "Unable to connect to MySQL" );

// select a database to work with
$selected = mysql_select_db ( "taxogram", $dbhandle ) or die ( "Could not select login" );

// execute the SQL query and return records
$result = mysql_query ( "INSERT INTO liker ( imageId , likerId ) VALUES ( '$imageId' , '$likerId' ) " );
echo mysql_error () . "<br>";
if ($result == 1) {
    echo "sukses";
} else {
    echo "gagal";
}
?>

错误

您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在第 1 行的 'like ( imageId , likerId ) VALUES ( '1' , '2' )' 附近使用的正确语法嘎嘎

Answer 1

“喜欢”是reserved keyword .

$result = mysql_query ( "INSERT INTO `like` ( imageId , likerId ) VALUES ( '$imageId' , '$likerId' ) " );

另请注意 mysql_ functions are deprecated 。请改用 Mysqli 或 PDO。
