我正在尝试编写一个代码，使用PHP将文档直接上传到phpMyAdmin。我尝试了这个代码，它看起来像它的工作，没有错误，但数据没有上传到数据库..有人可以帮助指出问题吗？
<?php
$host="localhost";
$username = "root";
$password = "";
$database= "schoolydb";
$connect = new mysqli($host,$username,$password,$database);
$connect ->set_charset("utf8");
$message = '';
if(isset($_POST["upload"]))
{
if($_FILES['product_file']['name'])
{
$filename = explode(".", $_FILES['product_file']['name']);
if(end($filename) == "csv")
{
$handle = fopen($_FILES['product_file']['tmp_name'], "r");
while($data = fgetcsv($handle))
{
$student_id = mysqli_real_escape_string($connect, $data[0]);
$student_login = mysqli_real_escape_string($connect, $data[1]);
$student_password = mysqli_real_escape_string($connect, $data[2]);
$student_first_name = mysqli_real_escape_string($connect, $data[3]);
$student_last_name = mysqli_real_escape_string($connect, $data[4]);
$student_phone_number = mysqli_real_escape_string($connect, $data[5]);
$student_gender = mysqli_real_escape_string($connect, $data[6]);
$original_back_school = mysqli_real_escape_string($connect, $data[7]);
$original_end_time = mysqli_real_escape_string($connect, $data[8]);
$original_class = mysqli_real_escape_string($connect, $data[9]);
$class_Halom= mysqli_real_escape_string($connect, $data[10]);
$parent_id = mysqli_real_escape_string($connect, $data[11]);
$teacher_id = mysqli_real_escape_string($connect, $data[12]);
$query = "INSERT INTO `student`(`student_id`, `student_login`, `student_password`, `student_first_name`, `student_last_name`, `student_phone_number`, `student_gender`, `original_back_school`, `original_end_time`, `original_class`, `class_Halom`, `parent_id`, `teacher_id`) VALUES ($student_id, '$student_login','$student_password','$student_first_name','$student_last_name', '$student_phone_number','$student_gender','$original_back_school',' $original_end_time','$original_class','$class_Halom','$parent_id','$teacher_id') ";

该行存在错误
$query = "INSERT INTO `student`(`student_id`, `student_login`, `student_password`, `student_first_name`, `student_last_name`, `student_phone_number`, `student_gender`, `original_back_school`, `original_end_time`, `original_class`, `class_Halom`, `parent_id`, `teacher_id`) VALUES ($student_id, '$student_login','$student_password','$student_first_name','$student_last_name', '$student_phone_number','$student_gender','$original_back_school',' $original_end_time','$original_class','$class_Halom','$parent_id','$teacher_id') ";
$student_id不是写在' '它应该像'$student_id'所以实际代码将是
$query = "INSERT INTO `student`(`student_id`, `student_login`, `student_password`, `student_first_name`, `student_last_name`, `student_phone_number`, `student_gender`, `original_back_school`, `original_end_time`, `original_class`, `class_Halom`, `parent_id`, `teacher_id`) VALUES ('$student_id', '$student_login','$student_password','$student_first_name','$student_last_name', '$student_phone_number','$student_gender','$original_back_school',' $original_end_time','$original_class','$class_Halom','$parent_id','$teacher_id') ";
这将解决您的问题。
由于您使用的是.csv文件，因此您可以告诉PHP您的分隔符是分号。
<?php
while (($data = fgetcsv($handle, 1000, ";")) !== FALSE)
?>要搜索文件的每个值，您可以使用以下策略：
<?php
$row = 0;
if (($handle = fopen("c:\\temp\\test.csv", "r")) !== FALSE)
{
//Searching line by line of the file
while (($data = fgetcsv($handle, 1000, ";")) !== FALSE)
{
$num = count($data);
$row++;
//Searching column by column of the current line
for ($col = 0; $col < $num; $col++)
{
//Here you can use the desired values
switch ($col) {
case 0:
$student_id = mysqli_real_escape_string($connect,$data[$col]);
break;
case 1:
$student_login = mysqli_real_escape_string($connect,$data[$col]);
break;
case 2:
$student_password = mysqli_real_escape_string($connect,$data[$col]);
break;
case 3:
$student_first_name = mysqli_real_escape_string($connect,$data[$col]);
break;
case 4:
$student_last_name = mysqli_real_escape_string($connect,$data[$col]);
break;
case 5:
$student_phone_number = mysqli_real_escape_string($connect,$data[$col]);
break;
case 6:
$student_gender = mysqli_real_escape_string($connect,$data[$col]);
break;
case 7:
$original_back_school = mysqli_real_escape_string($connect,$data[$col]);
break;
case 8:
$original_end_time = mysqli_real_escape_string($connect,$data[$col]);
break;
case 9:
$original_class = mysqli_real_escape_string($connect,$data[$col]);
break;
case 10:
$class_Halom = mysqli_real_escape_string($connect,$data[$col]);
break;
case 11:
$parent_id = mysqli_real_escape_string($connect,$data[$col]);
break;
case 12:
$teacher_id = mysqli_real_escape_string($connect,$data[$col]);
break;
}//end switch
}//endfor (columns of each line)
//If your file has a header and you wish to skip it, you can do something like this:
//if ($row > 1) { //create your query and execute it... }
$query = "INSERT INTO `student`(`student_id`, `student_login`, `student_password`, `student_first_name`, `student_last_name`, `student_phone_number`, `student_gender`, `original_back_school`, `original_end_time`, `original_class`, `class_Halom`, `parent_id`,`teacher_id`) VALUES ";
$query.= "($student_id, '$student_login','$student_password','$student_first_name','$student_last_name','$student_phone_number','$student_gender','$original_back_school','$original_end_time','$original_class','$class_Halom', $parent_id, $teacher_id) ";
