Getting the host URLs from a list of URLs submitted

Hello All,

I have a list of URLs submitted by users. I want to make sure: list has no White-spacing, and it contains only host values

i.e site.com,subdomain.site.com,site2.com,site3.net

I have the following code at the moment

var list = document.getElementById( "list" ).value ;

Taking out the white spaces in list

$vars = array_map('trim', explode(',', $list));  

is $list ok here? I am a newb and not sure the diff b/w $ and var

making sure list only contains host values of the intended URLs (from php manual)

function getHost($list) { 
   $parseUrl = parse_url(trim($list)); 
   return trim($parseUrl[host] ? $parseUrl[host] : array_shift(explode('/', $parseUrl[path], 2))); 
} 

This would only work for one address at a time, can some one help me to make it work for the whole list? Need to iterate this method through the comma separated list

Appreciate all your help.

$list = explode(',', $vars);

foreach ($list as $key => $host) {
      $list[$key] = getHost($host);
}

var_dump($list);

Should do what you want.

Hi,

Thanks for the reply and help.

It was pointed out to me that

var list = document.getElementById( "list" ).value ;

is Javascript when I try the php code it just won't even submit the form.

This is what i have so far.

function startProcess() 
{
	var channelname = document.getElementById( "channelname" ).value ;		
	var sitename = document.getElementById( "sitename" ).value ;
	//sending private url example.com or null
	var privateurl = document.getElementById( "privateurl" ).value ;
	//?sending privateURL check 1 or 0?
	var privateurlcheck = document.getElementById( "privateurlcheck" ) ;
	//no value with nothing , checked always 0, with value it is 0
	//sending new values		

	if (privateurlcheck.checked == true) {
	var privateurlcheck = 1;
	// do something
	} else {
	var privateurlcheck = 0;}

	$vars = array_map('getHost', explode(',', $privateurl));

	http.open('get', "ajax/createchannel.php?channel=" + channelname + "&sitename=" + sitename + "&privateurl=" + privateurl + "&privateurlcheck=" + privateurlcheck);
	http.onreadystatechange = handleProcessResponse;
	http.send(null);
}

function getHost($url) 
{ 
	$parseUrl = parse_url(trim($url)); 
	return trim($parseUrl[host] ? $parseUrl[host] : array_shift(explode('/', $parseUrl[path], 2)));
}

You're setting a javascript variable and expecting to use it within your PHP code!. You cannot mix Javascript with PHP, they are completely different languages.

Thanks for pointing that out. I realised this and now focusing on doing this on JavaScript

var list = document.getElementById( "list" ).value ;
var host = getHostname(str);

function getHostname(str) {
var re = new RegExp('^(?:f|ht)tp(?:s)?\://([^/]+)', 'im');
        return str.match(re)[1].toString();
}

I think above will just get rid of  ftp://, http://, and https:// prefixe but nothing more. Any ideas?

What do you need help with Javascript or PHP? This is a PHP forum for PHP code only. Javascript support is provided in the Javascript forum.

I think I have to do this using JavaScript since my script uses JavaScript before sending the list variable to database.

Could some one move the thread?

Sorry for the confusion.

Hello Again to all the JavaScript pros. I've been moved here from php!

I have the following code and I want to make sure the [var privateurl] only contains comma separated host list

Originally when clients submit privateurl it would be a list with full urls and white space

i.e http://www.phpfreaks.com, domain.com/index.php, sub3.domain2.com,    site3.com

I want the list to be phpfreaks.com,domain.com,sub3.domain2.com,site3.com so that no white spaces and only host values of urls are sent to database.

var channelname = document.getElementById( "channelname" ).value ;		
	var sitename = document.getElementById( "sitename" ).value ;
	//sending private url example.com or null
	var privateurl = document.getElementById( "privateurl" ).value ;
	//?sending privateURL check 1 or 0?
	var privateurlcheck = document.getElementById( "privateurlcheck" ) ;
	//no value with nothing , checked always 0, with value it is 0
	//sending new values		

	if (privateurlcheck.checked == true) {
	var privateurlcheck = 1;
	// do something
	} else {
	var privateurlcheck = 0;}

	$vars = array_map('getHost', explode(',', $privateurl));

	http.open('get', "ajax/createchannel.php?channel=" + channelname + "&sitename=" + sitename + "&privateurl=" + privateurl + "&privateurlcheck=" + privateurlcheck);
	http.onreadystatechange = handleProcessResponse;
	http.send(null);
}

I have found teh following code

function getHostname(str) {
var re = new RegExp('^(?:f|ht)tp(?:s)?\://([^/]+)', 'im');
return str.match(re)[1].toString();
}

but was told it will only get ride of http, https, ftp

Can some one please help me with this?
