我遇到的问题是我的代码行没有显示提交按钮，同时它也没有进入我设置的数据库。
`<?php
/*

* Description: Upload Content Page
*/
//Includes
include 'connect.php'; //Connects to the DB
//Check if the form was submittedƒ
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$target_dir = "photo/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". htmlspecialchars( basename( $_FILES["fileToUpload"]["name"])). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
if ($conn->query($sql) === TRUE) { //run the querry and check if it went through
print "<strong>New Feedback added successfully</strong>";
}else{
print "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close(); //Close the connection
header('location:'.$_SERVER['PHP_SELF'].'?done'); //re-direct to success page (so they can't refresh)
}
if (isset($_GET['done'])) { //Show success message
print "<strong>" .@$title. " added successfully</strong>"; //The @ sign causes the error to bypass the error log
}

我尝试了我在网上找到的东西，但没有帮助。我正在考虑启动将文件上传到数据库的过程的各种提交按钮。
