我的文件上传时出现此问题.我尝试上传我的PDF文件,同时检查验证是否TMP_NAME为空,当我检查$_FILES['document_attach']['error']值为1时,这意味着有一个错误.

但是当我尝试上传其他PDF文件时,它已成功上传.为什么其他PDF文件没有？

HTML

<form action="actions/upload_internal_audit.php" method="post" enctype="multipart/form-data">
   <label>Title</label>
   <span><input type="text" name="title" class="form-control" placeholder="Document Title"></span>  
   <label>File</label>  
   <span><input type="file" name="document_attach"></span><br>
   <span><input type="submit" name="submit" value="Upload" class="btn btn-primary"></span>
</form>

PHP

if(isset($_POST['submit'])){

$title = $_POST['title'];
$filename = $_FILES['document_attach']['name'];
$target_dir = "../eqms_files/";
$maxSize = 5000000;

if(!empty($title)){

    if(is_uploaded_file($_FILES['document_attach']['tmp_name'])){
        if ($_FILES['document_attach']['size'] > $maxSize) {
                echo "File must be: ' . $maxSize . '";
        } else {

                $result = move_uploaded_file($_FILES['document_attach']['tmp_name'], $target_dir . $filename);
                mysqli_query($con, "INSERT into internal_audit (id, title, file) VALUES ('', '".$title."', '".$filename."')");
                echo …

此代码需要刷新或单击页面才能进入索引页面,然后在会话过期后更新数据库.

如何在会话过期后自动更新数据库,以便用户激活为0而不刷新或点击页面？

$idletime = 3600; //after 1hr the user gets logged out

if (time() - $_SESSION['timestamp'] >= $idletime){
    $online = "UPDATE users SET active = 0 WHERE username = '".$_SESSION['username']."'";
    mysqli_query($con, $online);
    session_destroy();
    header("Location:index.php");
} else {
    $_SESSION['timestamp'] = time();
}

我有这个代码。有人可以帮助我如何删除文件上传时的 fakepath 吗？谢谢你

html代码

<div id="file">Chose file</div>
<input type="file" name="file" style="display:none;"/>

查询代码

var wrapper = $('<div/>').css({height:0,width:0,'overflow':'hidden'});
var fileInput = $(':file').wrap(wrapper);

fileInput.change(function(){
 $this = $(this);
 $('#file').text($this.val());
})

$('#file').click(function(){
 fileInput.click();
}).show();
