Question

目前我正在使用php上传文件到数据库。所以我成功上传了这个文件。在数据库中显示了文件的路径，但是我检查数据库中的文件是不存在的。

以下是数据库数据，您可以在圆圈部分看到路径正确。

在我的数据库下面没有任何文件

以下是我的代码，希望有人能帮我弄清楚我的错误部分在哪里。

submit.php

$ideaTopic = $_POST['ideaTopic'];
$ideaCategories = $_POST['ideaCategories'];
$ideaContent = $_POST['ideaContent'];
$ideaChooseFile = $_POST['ideaChooseFile'];
$anonymous = $_POST['anonymous'];
$checkbox_term = $_POST['checkbox_term'];
$getfile = $_FILES["uploadfile"]['name'];

$complete = true;

if ($_SERVER["REQUEST_METHOD"] == "POST") {

if ($checkbox_term != "accpected") {
    $termIsNotCheck = true;
    $complete = false;
}
else{
    $termIsNotCheck = false;
}

if (empty($ideaTopic)) {
    $isEmpty_topic = true;
    $complete = false;

}
else{
    $isEmpty_topic = false;
}

if (empty($ideaCategories)) {
    $isEmpty_categories = true;
    $complete = false;

}

else{

if (empty($ideaContent)) {
    $isEmpty_content = true;
    $complete = false;

}

else{

通过移动文件，您必须使用绝对值而不是新文件的相对路径。

move_uploaded_file($sourcePath, __DIR__."/".$targetPath);
