domain purchasing app

[Anon]

Im aiming to create/modify/use an application that allows users to check domains and purchase available ones

the following script allows a person to check the whois output of a domain search

<form method="POST" action= "<?PHP echo($PHP_SELF); ?>">
Find an available domain name from Network Solutions:
<P>
<INPUT name="domain" SIZE="20" MAXLENGTH="22">
<P>
<INPUT TYPE="SUBMIT" VALUE="Check name">
<INPUT TYPE="RESET" VALUE="Clear">
</P>
</FORM>
<hr>
<font size="2"><pre>
<?
//This function was found at : http://www.phpwizard.net/phpTidbits/
function whois($domain, $server="www.geektools.com")
{
$fp = fsockopen ($server, 43, &$errnr, &$errstr) or die("$errno: $errstr");
fputs($fp, "$domain\n");
while (!feof($fp))
echo fgets($fp, 2048);
fclose($fp);
}
?>
<?
If (isset ($domain)){
echo (whois($domain));
}
?>
</pre></font>

thing is id like to be able to "filter" the returned information, so that i can add hyperlinks to certain aspects such as domain names, or remove other aspects that i do not wish to return.

I know its possible, via use of some kind of string search approach to achieve this, but im unsure how to go about it, and time isnt a luxury i have. Id be grateful if someone could point me in the right direction so that i can begin the process of attacking the problem via the shortest possible route.

if someone has a working app or knows where i can get one that would be even better still.

tia for any help offered

Part of your info is missing what do you want to do with the returning data??

[Anon]

depends on the actions of the user.

essentially id like to be able to tell them whether the names available or not.

i dont really want to tell them who owns it when it was purchased etc etc.

on the following output

Query: egbutnoturd.co.uk
Registry: whois.nic.uk
Results:

No match for "EGGSBUTNOCHEESE.CO.UK".

WHOIS database last updated at 00:09:00 11-Jan-2002

The NIC.UK Registration Host contains ONLY information for domains
within co.uk, org.uk, net.uk, ltd.uk and plc.uk. Please use the whois
server at rs.internic.net for Internet Information or the whois server
at nic.ddn.mil for MILNET Information.

Results brought to you by the GeekTools WHOIS Proxy

Server results may be copyrighted and are used with permission.

I WOULD like to catch the line beginning No match (which ends in) ".

which would be returned inside the <a href> tags in the returning page.

by clicking the link the user would be taken to another page that returned the domain name inside a form and requested other personal info which in turn, would update my db and be processed at a payment gateway such as world pay.

try changing the whois function to.
<?

function whois($domain, $server="www.geektools.com")
{
$fp = fsockopen ($server, 43, &$errnr, &$errstr) or die("$errno: $errstr");
fputs($fp, "$domain\n");
while (!feof($fp))
{
$linein=fgets($fp, 2048);
if ( substr($linein, 0, 8) == "No Match" )
{
return(0);
}
}
fclose($fp);
return(1);
}

if ( isset($domain) )
{
if ( whois($domain) )
{
echo "The domain is already taken";
}
else
{
echo "The domain is free";
}
}
?>

I think that will work.

[Anon]

thanks for trying but it doesnt work.

returns domain already taken for every query

<form method="POST" action= "<?PHP echo($PHP_SELF); ?>">

<P>
<INPUT name="domain" SIZE="20" MAXLENGTH="22">
<P>

function whois($domain, $server="www.geektools.com")
{
$fp = fsockopen ($server, 43, &$errnr, &$errstr) or die("$errno: $errstr");
fputs($fp, "$domain\n");
while (!feof($fp))
{
$linein=fgets($fp, 2048);
if ( substr($linein, 0, 8) == "No Match" )
{
return(0);
}
}
fclose($fp);
return(1);
}

if ( isset($domain) )
{
if ( whois($domain) )
{
echo "The domain is already taken";
}
else
{
echo "The domain is free";
}
}
?>
</pre></font>

I coulden't check it to see if it works because the firewall blocks that port. try changing the substr command it may be checking the wrong number of bytes.

Mark.

[Anon]

do you mean this one

if ( substr($linein, 0, 8) == "No Match" )

or this one

$linein=fgets($fp, 2048);

the original script used this value for fgets

($fp, 2048);

i tried altering this to 1024 and 4096 but it made no difference to the outcome.

[khaine]

I ment that the substr may need altering to use less chars try

if ( substr($linein, 0, 2) == "No" )

It might match better

Mark.

[khaine]

Actually chnge of plan try replacing

if ( substr($linein, 0, 2) == "No" )

with

if ( strncmp($linein, "No Match", 5) == 0 )

It should do a better comparision

Mark.

[Anon]

tried both mark, 🙁 same outcome

all queries give me domain already taken.

[khaine]

Ive been a bit of a clot. The 'm' on match isent uppercase.

try this instead.

function whois($domain, $server="www.geektools.com")
{
$fp = fsockopen ($server, 43, &$errnr, &$errstr) or die("$errno: $errstr");
fputs($fp, "$domain\n");
while (!feof($fp))
{
$linein=strtoupper(fgets($fp, 2048));
if ( strncmp($linein, "NO MATCH", 8) == 0 )
{
return(0);
}
}
fclose($fp);
return(1);
}

Mark.

[Anon]

thanks mark

that works any ideas as to how id apply those principles so that domain available

would appear inside the <a href> tag

eg
<a href process.php?domainname>domain available</a>

i guess it would say something like domain available click to register.

consequently would i have to run 2 queries so that the domain name aspect is filtered seperately..

ill elaborate later as ive got to pick the kids up..

[khaine]

Well you already hold the name of the domain in the domain variable all you need to do is output it.

echo "<A href=\"process.php?domain=".$domain.">Domain Available</A>";

Simple as that

(prior to your changes) the geektools whois script found in the first post, queried whatever extension the individual put on the back of their searched domain, looped through all the available
whois registrars and returned the results.

it did this by looking for the . and proceeded on the basis of what followed eg co com etc

however since the introduced changes as below, if the domain extension is now attached to the query, eg unusualname.com it returns no match whereas if the extension is omitted it comes up as being available.

why would it do this?

<form method="POST" action= "<?PHP echo($PHP_SELF); ?>">
Find an available domain name from Network Solutions:
<P>
<INPUT name="domain" SIZE="20" MAXLENGTH="22">
<P>
<INPUT TYPE="SUBMIT" VALUE="Check name">

</P>
</FORM>

<?

function whois($domain, $server="www.geektools.com")
{
$fp = fsockopen ($server, 43, &$errnr, &$errstr) or die("$errno: $errstr");
fputs($fp, "$domain\n");
while (!feof($fp))
{
$linein=strtoupper(fgets($fp, 2048));
if ( strncmp($linein, "NO MATCH", 8) == 0 )

{
return(0);
}
}
fclose($fp);
return(1);
}

if ( isset($domain) )
{
if ( whois($domain) )
{
echo "The domain is already taken";
}
else
{
echo "<a href=\"process.php?domain=.$domain.\">the domain is free</a>";
}
}
?>
</pre></font>

no problem just drop the extension

<form method="POST" action= "<?PHP echo($PHP_SELF); ?>">
Find an available domain name from Network Solutions:
<P>
<INPUT name="domain" SIZE="20" MAXLENGTH="22">
<P>
<INPUT TYPE="SUBMIT" VALUE="Check name">
<INPUT TYPE="RESET" VALUE="Clear">
</P>
</FORM>
<hr>

<?

function whois($domain, $server="www.geektools.com")
{
$fp = fsockopen ($server, 43, &$errnr, &$errstr) or die("$errno: $errstr");
fputs($fp, "$domain\n");
while (!feof($fp))
{
$linein=strtoupper(fgets($fp, 2048));
if ( strncmp($linein, "NO MATCH", 8) == 0 )

{
return(0);
}
}
fclose($fp);
return(1);
}

if ( isset($domain) )
{

$bits=explode(".", $domain);
$domain=$bits[0];
if ( whois($domain) )
{
echo "The domain is already taken";
}
else
{
echo "<a href=\"process.php?domain=.$domain.\">the domain is free</a>";
}
}
?>

cures that prob, but the hyper link created as a result loses the extension.

how do i re attach it to the hyperlink?

good stuff mark, seems to work fine with coms and nets and orgs etc, but runs into problems with double extensions eg .co.uk etc

lots of food for thought though, thanks very much

[khaine]

I did forget about them.

replace

if ( $bits[1] != "" )
{
$domain.=".".$bits[1];
}

with

for ( $loop=1; $loop<count($bits); $loop++ )
{
if ( $bits[$loop] != "" )
{
$domain.=".".$bits[$loop];
}
}

this will take care of any number of dot on the end.

superb!! its at times like these i realise how very little i know.
