我已经尝试使用逗号和“AND”语句进行查询,如下图所示。我收到语法错误

Something went wrong.You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'are available 24/7 by phone and email to answer any questions and to assist you ' at line 1

每次我尝试这个查询时:

$sql = mysql_query("UPDATE general
SET bookabandheading = $_POST[bookabandheading
AND bookaband = $_POST[bookaband]
AND contactus = $_POST[contactus]
AND aboutuslisten = $_POST[aboutuslisten]
AND contactusheading = $_POST[contactusheading]
AND nightclubsheading = $_POST[nightclubsheading]
AND acousticheading = $_POST[acousticheading]
AND schoolsheading = $_POST[schoolsheading]
AND privateheading = $_POST[privateheading]
AND concertsheading = $_POST[concertsheading]
AND festivalsheading = $_POST[festivalsheading]
AND submissions = $_POST[submissions]
AND interns = $_POST[interns]
AND managementbio = $_POST[managementbio]
AND latestnews = $_POST[latestnews]
AND artistofthemonth = $_POST[artistofthemonth]
AND artistofthemonthphoto = $_POST[artistofthemonthphoto]
AND artistofthemonthid = $_POST[artistofthemonthid]
AND listentoourartists = $_POST[listentoourartists]
AND musicianswanted = $_POST[musicianswanted]
AND aboutus = $_POST[aboutus]
AND bshowcases = $_POST[bshowcases]
AND bandavails = $_POST[bandavails]");

查询在另一个 VPS 上的不同数据库中有效,但我刚刚迁移了服务器,但它不再有效。非常感谢任何帮助!

最佳答案

虽然主要问题是您错过了 bookamandheading 后的右括号,但我仍然建议您重构此请求,例如:

$keys = array("bookabandheading", "bookaband", "contactus", "aboutuslisten",
"contactusheading", "nightclubsheading", "acousticheading",
"schoolsheading", "privateheading", "concertsheading",
"festivalsheading", "submissions", "interns", "managementbio",
"latestnews", "artistofthemonth", "artistofthemonthphoto",
"artistofthemonthid", "listentoourartists", "musicianswanted",
"aboutus", "bshowcases", "bandavails");
$set = array();
foreach ($keys as $key) {
$set[] = sprintf(" %s = '%s' ", $key, mysql_escape_string($_POST[$key]));
}
$sql = mysql_query("UPDATE general SET " . implode(", ", $set));

通过转义输入更容易维护,也更安全。

更新:添加where语句示例

$where = array();
$where[] = sprintf(" some_string = '%s' ", mysql_escape_string($some_string));
$where[] = sprintf(" some_integer = %d ", $some_integer);
$where = " WHERE " . implode(" AND ", $where);
$sql = mysql_query("UPDATE general SET " . implode(", ", $set) . " " . $where);
