警告：mysqli_query（）期望参数1为mysqli错误

Question

include_once("php/db_connects.php");

$tbl_status = "CREATE TABLE IF NOT EXISTS status ( 
                id INT(11) NOT NULL AUTO_INCREMENT,
                osid INT(11) NOT NULL,
                account_name VARCHAR(16) NOT NULL,
                author VARCHAR(16) NOT NULL,
                type ENUM('a','b','c') NOT NULL,
                data TEXT NOT NULL,
                postdate DATETIME NOT NULL,
                PRIMARY KEY (id) 
                )"; 
$query = mysqli_query($tbl_status, $db_connects); 
if ($query === TRUE) {
    echo "<h3>status table created </h3>"; 
} else {
    echo "<h3>status table NOT created </h3>"; 
}

我不断收到mysqli错误。 我很确定我没有在PHP中使用msql。

Answer 1

改变这个

$query = mysqli_query($tbl_status, $db_connects); 

至

$query = mysqli_query($db_connects, $tbl_status); 

示例mysqli_query（mysqli $ link，字符串$ query）

Answer 2

mysqli_query的签名为：

mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )

假设$db_connects是存储mysqli_connect结果的mysqli_connect ，则需要翻转参数以适合：

mysqli_query($db_connects, $tbl_status);
