我继承了一个网站，其中包含一系列最初使用mysql_query编码的数据库查询。 由于对zen cart的更新，从mysql迁移到mysqli这些查询必须更新。由于将查询更改为mysqli，因此函数已损坏。
原始查询是：
function insert_FENQUIRY() {
$sql = sprintf('INSERT INTO FENQUIRY
(ENREGION, ENNAME, ENCOMP, ENADD1, ENADD2, ENADD3, ENCNTY, ENPCODE, ENCNTRY, ENTEL, ENDATE, ENDATELCON, ENCAT, ENCONSRS, ENADVER, ENTYPE, EN_CUSTOMER_ID)
SELECT
(SELECT region FROM postcode2region WHERE ab.entry_postcode REGEXP CONCAT("^", postcode_prefix, "[:digit:]*") ORDER BY postcode_prefix DESC LIMIT 1) AS ENREGION,

$_SESSION['customer_id']);
mysql_query($sql) or error_log("KG insert_FENQUIRY() : ". mysql_error());
return mysql_insert_id();
}
function insert_FENQCON() {

return mysql_insert_id();
}
function update_FENQCON_with_login() {

$q = mysql_query(sprintf('

$_SESSION['customer_id'] = insert_FENQCON();
error_log("KG New FENQCON added with ENCON_ID: ". $_SESSION['customer_id']);
$flag_insert_into_FENQUIRY = true;
}
此时一切正常。 更新了查询以使用如下所示的mysqli，它现在只能部分运行。

$connect = mysqli_connect(DB_SERVER, DB_SERVER_USERNAME, DB_SERVER_PASSWORD, DB_DATABASE);
$sql = sprintf('INSERT INTO FENQUIRY

正确地将数据写入FENQCON表，但没有任何内容写入FENQUIRY表。我可以看到这是由于上述查询失败导致$ flag_insert_into_FENQUIRY = true;永远不会跑步。
任何mysqli专家都能指出我正确的方向，因为我看不到代码失败的原因。我已经阅读了关于mysql到mysqli转换的无数帖子，我想我已经正确完成了。
答案 0 :(得分：0)
试试这个......
$q = mysqli_query($connect,$sql) or die(mysqli_error($connect));
更新：
既然您已经解决了上述问题，那么您似乎需要解决将Levenshtein库添加到MySQL安装中的新问题，以便运行levenshtein_ratio()函数。这可能有所帮助：https://samjlevy.com/mysql-levenshtein-and-damerau-levenshtein-udfs/
