PHP Uploading & .htaccess

John — Tue, 15 Dec 2009 19:06:44 +0000

For the senior developers, this is common knowledge in your tool box. For others, it can be quite a hassle to get your app working. Throw in some GoDaddy or similiar hosting service and you’ve got a nightmare.

Here are a couple examples to help you with uploading in PHP..

Open your .htaccess file or create one in a txt editor now. Add the below to the bottom of your .htaccess:

php_value upload_max_filesize 20M  //Add your max upload size here
php_value post_max_size 20M //this sets the filesize limit while using POST in your form

For those of you with sluggish servers, shared hosting or large files, it may benefit you to up the maximum execution time so that the upload doesn’t timeout during the process

php_value max_execution_time 200
php_value max_input_time 200

That’s a wrap, there are plenty of other resources available on php and .htaccess, just google it.

FileZilla Server User Management through PHP API

John — Sat, 05 Sep 2009 04:13:32 +0000

This is the start of what is going to be a small series on developing a modern approach to managing FileZilla through an API. Primarily, I will develop in PHP and will eventually port the code into Ruby.

It really is a work in progress and my primary goal is to get it to a point where I can manage users through an API. I chose XML to start with and will also port into JSON at a later time. It is important to note that while I prefer the *nix system, I needed to set this up on a MS box, not that I wanted to, believe me. The code is so rough it is bound to have some issues, if you see anything worth noting, please point it out!

Also, this work is to be released under the GPL so please feel free to use it as you like and give credit where credit is due.

To start, lets load the FileZilla server.xml file and parse the XML:

//XML location
$serverFile="FileZilla server.xml";
 
//New XML Object
$xmlobj = new SimpleXMLElement($serverFile, NULL, true);

At the moment, this will add a user based on pre-defined settings stored in an array, so lets set the variables and add the new children to the parent node:

$entryUserOption=array("Pass"=>	$pid,
"Group"=>					"clients",
"Bypass server userlimit"=>	        "2",
"User Limit"=>			                "0",
"IP Limit"=>					"0",
"Enabled"=>					"2",
"Comments"=>				        "none",
"ForceSsl"=>				        "2");
 
////////////////////////////////////////////////////////
$entryPermOption=array("FileRead"=>	"1",
"FileWrite"=>					        "1",
"FileDelete"=>				                "1",
"FileAppend"=>				        "0",
"DirCreate"=>				                "1",
"DirDelete"=>				                "1",
"DirList"=>					        "1",
"DirSubdirs"=>				                "1",
"IsHome"=>					        "1",
"AutoCreate"=>				        "0");
 
	$user = $xmlobj->Users->addChild("User");
	$user->addAttribute("Name",$uid);	
 
	foreach($entryUserOption as $key => $value){
 
	    $options = $user->addChild("Option",$value);
	    $options->addAttribute("Name",$key);
	}

So we now have the Users node created, nested a child node called User and iterated through the options array and set the Option node attributes. Next up, create the remaining children nodes for User:

	$options = $user->addChild("IpFilter");
	$options->addChild("Disallowed");	
	$options->addChild("Allowed");
 
	$options = $user->addChild("Permissions");
	$option = $options->addChild("Permission");
	$option->addAttribute("Dir",$homeDir);
 
		foreach($entryPermOption as $k => $v){
 
			$option = $options->addChild("Option",$v);
			$option->addAttribute("Name",$k);	
		}
 
	$options = $user->addChild("SpeedLimits");
	$options->addAttribute("DlType","0");
	$options->addAttribute("DlLimit","10");
 
	$option = $options->addChild("Download");
	$option->addChild("Upload");

Last but not least, lets print the XML so we can see what we are looking at:

print $xmlobj->asXML();

I’m not going to put the entire contents of the FileZilla server.xml file but you should have something similar to the below:

 Name="testuser">
 Name="Pass">******>
 
 Name="Group">clients>
 Name="Bypass server userlimit">2>
 Name="User Limit">0>
 Name="IP Limit">0>
 Name="Enabled">2>
 Name="Comments"/>
 Name="ForceSsl">2>
>
/>
/>
>
 
>
 Dir="C:\ftp\clients\testuser">
 Name="FileRead">1>
 Name="FileWrite">1>
 Name="FileDelete">1>
 Name="FileAppend">0>
 Name="DirCreate">1>
 Name="DirDelete">1>
 Name="DirList">1>
 Name="DirSubdirs">1>
 
 Name="IsHome">1>
 Name="AutoCreate">0>
>
>
 DlType="0" DlLimit="10" ServerDlLimitBypass="2" UlType="0" UlLimit="10" ServerUlLimitBypass="2">
/>
/>
>
>

The above code only grabs the XML file adds a new child and prints the XML. My next post will include the code to then save to FileZilla’s config file and reload at runtime. Again, feel free to contribute or comment..
