以下是我正在处理的php代码,当我将它放入phpMyAdmin(使用XAMPP)时插入查询似乎有效,但是$ status在这里运行查询时由于某种原因返回false ...我尝试了更改Insert语句和执行文件输出检查的每个组合,以查看问题的来源,但截至目前我已经完全陷入困境。有什么想法吗?
function addQuestion($question_to_add) {
global $host, $username, $password, $dbName, $user_table, $registered_user_table, $question_table;
global $answer_table, $user_answer, $user_post;
connectToDB($username, $password, $host, $dbName);
//$countQuery = "SELECT COUNT(QID) FROM questions";
//$count = mysql_fetch_array(mysql_query($countQuery))[0];//we fetch an array of counts for each column and return the count of column 0
$addQuestionQuery = "INSERT INTO questions (QID, UID, title, _timestamp, numRating, content, category, location) VALUES (0, 7, 0, 0, 0, 0, 0, 0)";
$status = mysql_query($addQuestionQuery);
if ($status == false) {// if the query failed, for whatever reason, let us know.
file_put_contents("out","false");
return false;
}
file_put_contents("out","true");
return true;
}
有用的:
function connectToDB($user, $password, $server_host, $db_name) {
$conn = mysql_connect($server_host, $user. $password);
if (!$conn) {
die("Could not connect: " . mysql_error());
//
}
mysql_select_db($db_name, $conn);
}
答案 0 :(得分:1)
连接上的参数错误:
$conn = mysql_connect($server_host, $user. $password);
^ . it should be ,
注意:使用更好的版本mysqli或PDO。 Mysql现已弃用,不再维护。
与往常一样,在调试时,请始终打开错误报告:
error_reporting(E_ALL);
ini_set('display_errors', '1');
mysql_error();
