PHP Unlinking

[system]

Need some help with php unlinking

Here is my php delete script

[php]<?php

$dir = dirname(FILE);
echo $dir;
$dir = “/Users/LUJO/Documents/CODE/REVLIVEGIT/wp-content/uploads/dropzone/”;
$pictures = $_POST[‘data’];
//print_r ($pictures);
$imageone = $pictures[0];

echo “”. $imageone;

$filename = $dir . $imageone;



echo '</br>' .$filename;

if (is_file($filename)) {

chmod($filename, 0777);

if (unlink($filename)) {
echo ‘File deleted’;
} else {
echo ‘Cannot remove that file’;
}

} else {
echo ‘File does not exist’;
}[/php]

This cannot find the file, however if i include the filename like so

[php]

<?php $dir = dirname(__FILE__); echo $dir; $dir = "/Users/LUJO/Documents/CODE/REVLIVEGIT/wp-content/uploads/dropzone/"; $pictures = $_POST['data']; //print_r ($pictures); $imageone = $pictures[0]; echo "". $imageone; $filename = $dir . test.jpg echo '' .$filename; if (is_file($filename)) { chmod($filename, 0777); if (unlink($filename)) { echo 'File deleted'; } else { echo 'Cannot remove that file'; } } else { echo 'File does not exist'; }[/php] It works fine, why can I not use a variable in the filename?

can you post the result of print_r ($pictures); so i can see the array.

Here is the result of my echo

added in print array

/[php]Users/LUJO/Documents/CODE/REVLIVEGIT/wp-content/themes/twentythirteen/incArray
(
[0] => 1420376775-medi.jpg

)
1420376775-medi.jpg
/Users/LUJO/Documents/CODE/REVLIVEGIT/wp-content/uploads/dropzone/1420376775-medi.jpg
File does not exist[/php]

try this:
[php]
$filename = $dir.’/’.$_POST[‘data’];

if(is_file($filename)) {
if (unlink($filename)) {
echo ‘File deleted’;
} else {
echo ‘Cannot remove that file’;
}
}
else {
echo ‘File does not exist’;
}[/php]

Let me know how you get on with this snippet.

Sorry for the late reply,

Surely that will break as you are trying to pass an Array to unlink and not a string?

I will give it a go though and let you know

It still has to be a string even though it is in an array ( I believe I’m correct???). I don’t see where it would break? However, I would just get rid of the that filename in the array if it is no longer needed

[php]unset($myFileNamesArray[‘example’]);[/php]

Indeed it will, (well it won’t break, but it won’t delete the file) what i was trying to find out if it is indeed an array.
Which leads me to, why have you created an array called data stored in an array called $_POST?

If it does balk on the $_POST, then add 0 like so [php]$_POST[‘data’][0][/php]

Let me know how you get on.

PS: sorry for the edit, i spotted a typo.

Agreed. 8)
I had already whittled down some of the OP’s post so I kept that line in (well the $filename reference) to keep it relevant to their post.
