PHP unlink doesn't delete

Question

This tiny problem has ruined my day. I can't delete files by PHP unlink function. I am creating PHP form to update and edit pdf files. Below is my piece of html form and PHP unlink script.

HTML

<form method="post" action="#" enctype="multipart/form-data">
<input type="file" value="<?php echo $row['img']?>" name="image">
<input type="submit" name="update">
</form>

PHP

<?php
if(isset($_POST['update']) && ($_FILES['image']['name'])){
$image=$_POST['image'];
unlink('../pdf/services/'.$image);
}

?>

Answer 1

Try $_FILES. Something like $image = $_FILES['image']; and then $imgname = $image['name'];

After that you can use unlink(); as you wanted (unlink("../pdf/services".$imgname);)

Hope I helped, It worked after my tests!

Answer 2

Whenever you try to remove a file using unlink, you will need to make sure that everything is ok:

1. Is the path I want to remove a file from available? Do I have access all the folders I need along the path? If not, then giving the necessary privileges will be needed.

2. Is my location the one I think it is? You will need to run getcwd() which is current working directory. If your page is not in the desired location, then compared to it the path you want to reach will mean a different thing

3. Is adding the path I want to the location I got at the second point correct and the one I expect?

If everything above is all right and you still have the problem, then check the error log, it might give you helpful information. If the problem still persists, then you will need to create a dummy file on the path you want to remove the other file from. Is the file created? Is it created at the correct location?
