【问题描述】：
我有一个按钮，单击时会显示一个表单。它可以在我们课堂上的工作站和云 ide 中使用，但不能在我的笔记本电脑上使用。其他项目可以在我的笔记本电脑上运行。
我收到以下错误：
警告：mysqli::query()：无法在第 7 行的 G:\Web Projects\kmbgis\assets\caseForm.php 中获取 mysqli
致命错误：在第 8 行对 G:\Web Projects\kmbgis\assets\caseForm.php 中的非对象调用成员函数 fetch_assoc()
这是caseForm.php中的PHP：
<?php
include('config.php');
//check any user action
$action = isset( $_POST['action'] ) ? $_POST['action'] : "";
$result = $conn->query("SHOW TABLE STATUS LIKE 'case_detail'");
$row = $result->fetch_assoc();
$nextCaseId = $row['Auto_increment'];
$result1 = $conn->query("SHOW TABLE STATUS LIKE 'suspect_data'");
$row1 = $result1->fetch_assoc();
$nextSuspectId = $row1['Auto_increment'];
$result2 = $conn->query("SHOW TABLE STATUS LIKE 'victim_data'");
$row2 = $result2->fetch_assoc();
$victimID = $row2['Auto_increment'];
//if the user hit the submit button on Case Detail
if($action == "Add"){
//Case Details Variables
$r_unit = $_POST['r_unit'];
$d_report = $_POST['d_report'];
$t_report = $_POST['t_report'];
$crimeCategory = $_POST['crime_category'];
$r_station = $_POST['r_station'];
if($crimeCategory == '101'){
$offenseType = $_POST['crime_type1'];
}else if($crimeCategory == '102'){
$offenseType = $_POST['crime_type2'];
}else if($crimeCategory == '103'){
$offenseType = $_POST['crime_type3'];
}else if($crimeCategory == '104'){
$offenseType = $_POST['crime_type4'];
}else if($crimeCategory == '105'){
$offenseType = $_POST['crime_type5'];
}else{
$offenseType = "NOT NULL";
}
//Insert Values
$sql = "INSERT INTO case_detail (ReportingUnit,DateOfReporting,TimeOfReporting,SuspectID,OffenseID,CrimeTypeID,VictimID,StationID)
VALUES('$r_unit','$d_report','$t_report','$nextSuspectId','$offenseType','$crimeCategory','$victimID','$r_station')";
if($conn->query($sql) === TRUE){
echo "<script>
window.location='https://localhost/kmbgis/assets/suspectArea.php?id=".$nextCaseId."';
</script>";
} else{
echo "Error: " . $sql . "<br>" . $conn->error;
}
}
$conn->close();
?>
当单击按钮时，它会以<?php include'caseForm'; ?> 插入到 casedetail.php 文件中。而且在那个 casedetail.php 我有 PHP 代码可以打开连接、显示查询并关闭连接。
connect.php 包含：
<?php
$servername = "localhost";
$username = "wis1-29";
$password = "Password";
$dbname = "wis1-29";
//Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
//Check connection
if($conn->connect_errno){
echo "Failed to connect to MySQL: (" . $conn->connect_errno . ") " . $conn->connect_error;
}
?>
这是包含 caseForm.php 的 casedetails.php。 由于某种原因，它也没有显示我的 footer.php。

你在哪里包含“connect.php”？
-
嗨尼塞！我将它包含在 casedetail.php 中，其中还包含了 caseForm.php。在caseForm 中，我还包含了connect.php。我做对了吗？就像我查询以在 casedetail.php 中显示结果时一样任务
