[SOLVED] Folder creation for image assortment

[EchoFool]

I have an image uploader script for users to upload but am wanting to divide the folders into subfolders based on user id, here is an example:

 

Say User ID 2 wanted to upload a image and there is no subfolder named "2" it will create it then place the image in:

 

images/2/image1.jpg

 

But if subfolder 2 is already in existance it will just add the image straight to the folder instead... how is this done? I have so far got this for my image upload script:

 

 

 <?php
if(isset($_POST['action'])){

//define a maxim size for the uploaded images in Kb
define ("MAX_SIZE","150"); 
[insert current track Signatune]
+ Additional Options...
//This function reads the extension of the file. It is used to determine if the file  is an image by checking the extension.
function getExtension($str) {
         $i = strrpos($str,".");
         if (!$i) { return ""; }
         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
}

//This variable is used as a flag. The value is initialized with 0 (meaning no error  found)  
//and it will be changed to 1 if an errro occures.  
//If the error occures the file will not be uploaded.
$errors=0;
	//reads the name of the file the user submitted for uploading
	$image=$_FILES['image']['name'];
	//if it is not empty
	if ($image) 
	{
	//get the original name of the file from the clients machine
		$filename = stripslashes($_FILES['image']['name']);
	//get the extension of the file in a lower case format
  		$extension = getExtension($filename);
		$extension = strtolower($extension);
	//if it is not a known extension, we will suppose it is an error and will not  upload the file,  
//otherwise we will do more tests
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
		{
	//print error message
?>
<font size="2" color="red"><strong>
Unknown extension for image! Can only have: jpg,jpeg,png or gif format!
</strong></font>
<?php
			$errors=1;
		}
		else
		{
//get the size of the image in bytes
//$_FILES['image']['tmp_name'] is the temporary filename of the file
//in which the uploaded file was stored on the server
$size=filesize($_FILES['image']['tmp_name']);

//compare the size with the maxim size we defined and print error if bigger
if ($size > MAX_SIZE*1024)
{
?>
<font size="2" color="red"><strong>
You have exceeded the size limit, perhaps find a photoshop expert to help lower the size limit for you on the forums unless you can do it yourself!
</strong></font>
<?php
$errors=1;
}
//we will give an unique name, for example the time in unix time format
$image_name=time().'.'.$extension;
//the new name will be containing the full path where will be stored (images folder)
$newname="images/userprofiles/".$image_name;
//we verify if the image has been uploaded, and print error instead
$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied) 
{
?>
<font size="2" color="red"><strong>
Copy unsuccessfull! Please try again!
</strong></font>
<?php
$errors=1;
	}	
}
}
//If no errors registred, print the success message
if($errors == 0) 
{
$Update = mysql_query("INSERT INTO userimages (UserID,Image)
		VALUES('{$row['GameID']}','$image_name')")
			Or die(mysql_error());
If(mysql_affected_rows()>0){
?>
Upload successfully complete!

<?php
}
    }
}
?>

 

Is it possible to do my idea, if so how do you do it ?

Hope you can help !

You'll probably want file_exists and mkdir

[EchoFool]

Is there a way to do if folder exists also ?

[jxrd]

file_exists() also checks dirs. Read the notes!!
