我知道这个问题已经被问了很多次，我试过很多其他的答案，但它并没有为我警告：mysqli_query（）：在我的代码无法获取的mysqli
在这里工作是我的
类<?php
class saveexceltodb
{
var $inputFileName;
var $tableName;
var $conn;
var $allDataInSheet;
var $arrayCount;
/**
* Create a new PHPExcel with one Worksheet
*/
public function __construct($table=0)
{
$this->initiatedb();
}
private function initiatedb(){
//var_dump($allDataInSheet);
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "xyx";
// Create connection
$this->conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$this->conn) {
die("Connection failed: " . mysqli_connect_error());
}
}
public function updateIntermidiate(){
$allocationeventwise=array();
mysqli_query($this->conn,"DELETE FROM `allocationeventwise` WHERE 1");
$sql = "INSERT INTO `allocationeventwise` (`empid`, `event1`, `event2`, `event3`, `event4`, `event5` `event6`, `event7`) VALUES ";
$result = mysqli_query($this->conn, "SELECT usdeal.empid , usdeal.event1 , usdeal.event2, usdeal.event3, usdeal.event4, usdeal.event5, usdeal.event6, usdeal.event7 , salary.salary from usdeal INNER JOIN salary ON usdeal.empid = salary.empid where usdeal.allocated=0");
$i=0;
if (mysqli_num_rows($result) > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
$i++;
$totaleventDays = $row["event1"]+$row["event2"]+$row["event3"]+$row["event4"]+$row["event5"]+$row["event6"]+$row["event7"];
$allocationeventwise[$row["empid"]]['event1']=($row['salary']/$totaleventDays)*$row["event1"];
$allocationeventwise[$row["empid"]]['event2']=($row['salary']/$totaleventDays)*$row["event2"];
$allocationeventwise[$row["empid"]]['event3']=($row['salary']/$totaleventDays)*$row["event3"];
$allocationeventwise[$row["empid"]]['event4']=($row['salary']/$totaleventDays)*$row["event4"];
$allocationeventwise[$row["empid"]]['event5']=($row['salary']/$totaleventDays)*$row["event5"];
$allocationeventwise[$row["empid"]]['event6']=($row['salary']/$totaleventDays)*$row["event6"];
$allocationeventwise[$row["empid"]]['event7']=($row['salary']/$totaleventDays)*$row["event7"];
$sql .='("'.$row["empid"].'",
'.$allocationeventwise[$row["empid"]]["event1"].',
'.$allocationeventwise[$row["empid"]]["event2"].',
'.$allocationeventwise[$row["empid"]]["event3"].',
'.$allocationeventwise[$row["empid"]]["event4"].',
'.$allocationeventwise[$row["empid"]]["event5"].',
'.$allocationeventwise[$row["empid"]]["event6"].',
'.$allocationeventwise[$row["empid"]]["event7"].',)';
if($i<mysqli_num_rows($result))
$sql .=",";
else
$sql .=";";
}
echo $sql;
if (mysqli_query($this->conn, $sql)) {
echo "New record created successfully<br/>";
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($this->conn);
}
} else {
echo "0 results";
}
}
}
当我使用它像这样
include('saveexceltodb.php');
$obj = new saveexceltodb(0);
$obj->updateIntermidiate();
我得到以下错误。
Warning: mysqli_query(): Couldn't fetch mysqli in C:\xampp\htdocs\import-excel\saveexceltodb.php
