Check if directory exists, make directory - php

Question

I'm having a little trouble with this. Thought it'd be easier, but turning out to frustrate. All I'm trying to do is have a text field where I can type the name of a new directory, check if that directory exists, and if not create it. I have found about 50 other people with almost the exact same code, so thought I had it correct but I keep getting Directory exists as per the "if" statement.
Eventually I want to tie this into my file upload script.
Here is the insert.php
<form action="" method="post" enctype="multipart/form-data" name="form1" id="form1">
<p>
<label for="directory">Directory:</label>
<input value="<?php if ($_POST && $errors) {
echo htmlentities($_POST['directory'], ENT_COMPAT, 'UTF-8');
}?>" type="text" name="directory" id="directory" />
</p>
<p>
<input type="submit" name="insert" id="insert" value="insert" />
</p>
</form>
And here is the post.php
try {
if (isset($_POST['insert'])) {
$directory = $_POST['directory'];
$photo_destination = 'image_upload/';
$path = $photo_destination;
$new_path = $path . $directory;
$mode = 0755;
if(!is_dir($new_path)) {
echo "The Directory {$new_path} exists";
} else {
mkdir($new_path , 0777);
echo "The Directory {$new_path} was created";
}
}
}

Answer 1

Change this :
if(!is_dir($new_path)) {
echo "The Directory {$new_path} exists";
}
to this :
if(is_dir($new_path)) {
echo "The Directory {$new_path} exists";
}
Try and tell me the result :)

Answer 2

Instead of using is_dir in the if block you can use file_exists. Because file_exists is the function to check whether file exists or not. For the same you can also refer to http://php.net/manual/en/function.file-exists.php

Answer 3

Try
if( is_dir( $new_path ) ) {
echo "The Directory {$new_path} exists";
}

Let someone wants to create a sub-folder,
with a year name under /uploads folderthen he/she want to create
another sub-folder under an /uploads/<year_name_folder>/,
named project_number.
$yearfolder = date('y');
if (!file_exists('uploads/'.$yearfolder)) {
mkdir("uploads/".$yearfolder);
}
*// Folder named by year has been created.*
$project_number = Any Unique field ,Come from database or anywhere !
$target_directory = mkdir("uploads/".$yearfolder."/".$project_number);
*// project number wise folder also created.
// If project number is not unique do check like year folder. I think every project number is unique.*
$target_dir = "uploads/$yearfolder/$project_number/";
*//my target dir has created where my document or pic whatever will be uploaded.*
Now Upload ! Woo
$target_file = $target_dir.($_FILES["file"]["name"]);
