警告：mysqli_query（）至少需要两个参数，其中一个参数在1579行的D:\wamp64\www\magento\includes\functions.php中给出

我再次需要一点帮助。。。我得到错误的mysql参数，我知道这个问题，但我找不到丢失的参数。。。这就是问题所在

**`$result_template = mysqli_query($select_template) or die(mysql_error());`**

我知道缺少1个参数，但我不知道是哪个参数？？你能帮我吗？谢谢

这是代码的一部分可能有用

/*function to display the active template*/


    function displayTemplate(){
        $tableprefix = "";
        global $tableprefix,$_SESSION;
        $template_array = array();

         $select_template = "SELECT vtop_filename,vleft_filename,vbottom_filename,vimages_folder,vcss_name,vtemplate_name
                            FROM ".$tableprefix."template_master WHERE vactive_status = 'Y'";

1579---->>>>   $result_template = mysqli_query($select_template) or die(mysql_error());

        $template_row = mysql_fetch_assoc($result_template);

        array_push($template_array,$template_row['vtop_filename'],$template_row['vleft_filename'],$template_row['vbottom_filename'],$template_row['vimages_folder'],$template_row['vcss_name'],$template_row['vtemplate_name']);

    return $template_array; 
    }

您需要告诉它连接到哪里。下面是一个从PHP连接到数据库的简单工作代码示例

 <php 

//Connect to DB 
$conn = new mysqli("Hostname","Username","Password","Database"); 

//If the connection has errors 
if ($conn->connect_error){ 
  //Display the error 
  die("Connection failed because: " . $conn->connect_error); 
} 

//Otherwise the connection is good so lets create a sql query 
$sql = "SELECT * FROM Database"; 

//Get the results of the query 
$result = $conn->query($sql); 

connect_错误）{
//显示错误
die（“连接失败，因为：“.$conn->connect\U错误”）；
} 
//否则连接很好，所以让我们创建一个sql查询
$sql=“从数据库中选择*”；
//获取查询结果
$result=$conn->query（$sql）；

您应该参考php文档了解这一点

由于您使用的是过程样式，因此必须将mysqli\u connect资源传递给mysqli\u查询

<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

/* Create table doesn't return a resultset */
if (mysqli_query($link, "CREATE TEMPORARY TABLE myCity LIKE City") === TRUE) {
    printf("Table myCity successfully created.\n");
}

/* Select queries return a resultset */
if ($result = mysqli_query($link, "SELECT Name FROM City LIMIT 10")) {
    printf("Select returned %d rows.\n", mysqli_num_rows($result));

    /* free result set */
    mysqli_free_result($result);
}

/* If we have to retrieve large amount of data we use MYSQLI_USE_RESULT */
if ($result = mysqli_query($link, "SELECT * FROM City", MYSQLI_USE_RESULT)) {

    /* Note, that we can't execute any functions which interact with the
       server until result set was closed. All calls will return an
       'out of sync' error */
    if (!mysqli_query($link, "SET @a:='this will not work'")) {
        printf("Error: %s\n", mysqli_error($link));
    }
    mysqli_free_result($result);
}

mysqli_close($link);
?>

您将连接变量传递给mysqli函数对不起@Kinshuk我无法理解您错过了连接对象…下面是快速语法ref
$res=mysqli\u query（$con\u object，$query）
mysqli\u查询（$conn，$select\u模板）
添加连接变量您已在某个变量中设置了mysqli\u连接。将该变量传递给第一个位置的函数。您将连接变量传递给mysqli函数对不起@Kinshuk我无法理解您错过了连接对象…下面是快速语法ref
