我无法恢复文件发送给我它是空的“！empty（$ _ FILES [”fileToUpload“] [”tmp_name“]）”

Question

I would like to retrieve the send files from the page ad.php to the page index.php . I already tried several methods but the input is empty in the page index.php

I use the JS function setInterval to check that the input is not empty in annonce.php but when it is retrieved it becomes empty

here are the two methods I use:

! Empty ($ _ FILES [ "fileToUpload"] [ "tmp_name"])

$ check = getimagesize ($ _ FILES ["fileToUpload"] ["tmp_name"])

annonce.php

            <div class="container">
                <div class="row">

Answer 1

Please confirm you use multipart/form-data inside the form

<form action="/action_page_binary.php" method="post" enctype="multipart/form-data">

It's better to try this to check the file is empty or not.

if ($_FILES['fileToUpload']['size'] == 0 && $_FILES['fileToUpload']['error'] == 0)
{
    // cover_image is empty (and not an error)
}

You can check the file size which is in the $_FILES array.

It's already defined in Check if the specified input file is empty
