How to Get Uploaded File Name with glob() Function? - php

Question

I have a form for users to upload files into the folder.
HTML and PHP codes are as below:
<form enctype="multipart/form-data" method="post" action="test.php">
<input type="text" name="name"/><br/>
<input type="file" name="photo" /><br/>
<input type="submit"/>
</form>
<?php //test.php
move_uploaded_file($_FILES["photo"]["tmp_name"], "testFolder/".$_POST["name"]);
?>
The upload form works well, and uploaded files are in the folder testFolder/ .
Now I want to use glob() function to get all file names in the folder.
<?php
foreach(glob("testFolder/*.*") as $file) {
echo $file."<br/>";
}
?>
However, it doesn't echo anything.
The glob() function works well on other folders, which contains existing files, not uploaded files.
But why doesn't it work on this folder with uploaded files ?

Answer 1

Possbile wildcard extension could be the issue.
It may be that glob does not allow wildcard extensions, i dont see any mention of this in the docs. Have you tried a directory iterator?
$dir = new DirectoryIterator(__DIR__.'/testFolder);
foreach ($dir as $file) {
echo $file->getFilename();
}
UPDATE: THE PATH IS NOT THE ISSUE
You are using a relative file path, therefore glob probably isn't finding the directory you are trying to search for.
Either the script calling the function needs to sit inside the parent directory of 'testFolder' or you need to use an absolute path like so.
<?php
foreach(glob("/absolute/path/to/testFolder/*.*") as $file) {
echo $file."<br/>";
}
?>
If you do want to use a relative path you could do the following:
<?php
//__DIR__ is a PHP super constant that will get the absolute directory path of the script being ran
// .. = relative, go up a folder level
foreach(glob(__DIR__."/../testFolder/*.*") as $file) {
echo $file."<br/>";
}
?>
Obviously the paths above are examples but should get you on the right track.
Hope this helps

Answer 2

Because I didn't give the extension for the uploaded file, that's why glob("testFolder/*.*") doesn't get anything.
Two solutions:
Give uploaded files an extension.
$ext = strrchr($_FILES["photo"]["name"], ".");
move_uploaded_file($_FILES["photo"]["tmp_name"],
"testFolder/".$_POST["name"].$ext);
Then, glob("testFolder/*.*") will be able to get these uploaded files with an extension.
Just change glob("testFolder/*.*") to be glob("testFolder/*")
