我在mysqli准备查询中遇到问题,我无法弄清楚出了什么问题。
在phpmyadmin中,我正在编写此查询
<body onload="load();">
<input class="zipCode inputfield" />
</body>
我得到了一个成功的结果。
当我尝试用mysqli prepare语句执行此操作时,我收到错误。
SELECT `country_id` FROM `oa_country` WHERE `name` = "Ελλάδα"
打印$ result打印这些数据。
function getCountryId($country) {
print($country); \\prints "Ελλάδα" or anything else, even countries in latin letters.
$db = mysqli_connect(DB_HOSTNAME,DB_USERNAME,DB_PASSWORD,DB_DATABASE);
$result = mysqli_prepare($db, "SELECT `country_id` FROM `oa_country` WHERE `name` = ? ;");
mysqli_stmt_bind_param($result, 's', $country);
mysqli_stmt_execute($result);
mysqli_stmt_bind_result($result, $countcountry);
print_r($result);\\ see below.
while(mysqli_stmt_fetch($result))
{
$countryid = $countcountry;
}
mysqli_stmt_close($result);
mysqli_close($db);
echo $countryid; \\undefined variable countryid
return $countryid;
}
奇怪的是,它过去常常起作用,但突然停止了,我无法解释原因!
P.S。所有插入都使用mysqli + prepare语句。 像这样的查询停止了工作。
更新1。
我在班级上面记录了这个错误
mysqli_stmt Object
(
[affected_rows] => -1
[insert_id] => 0
[num_rows] => 0
[param_count] => 1
[field_count] => 1
[errno] => 0
[error] =>
[error_list] => Array
(
)
[sqlstate] => 00000
[id] => 1
)
现在我收到了这个错误。
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
在Fatal error: Uncaught exception 'mysqli_sql_exception' with message 'Column 'country_id' cannot be null' in /some/url/lib/registerClass.php:49

变量之下,我将字符集设置为utf8。

答案 0 :(得分:1)
它看起来像charset问题
尝试设置mysqli_set_charset
