How do I send data onto a form on another site and retrieve the output?

[jwk811]

I may be pushing it here but I think it might be possible to do this like paypal does. When a visitor enters my site I want to send there IP address to another website and submit it and retrieve the output which would be their personal information. If there is something close to this that I could do, please help me out here. Thanks!

can you help me out with that fert? and is that going to do exactly what i want? i dont understand what to do.. thanks

[fert]

$curl=curl_init("url");

$values=array("ip"=>$_SERVER['REMOTE_ADDR']);
curl_setopt($curl,CURLOPT_POST,true);
curl_setopt($curl,CURLOPT_POSTFIELDS,$values);

$results=curl_exec($curl);

[jwk811]

will that work with any site or does that site have to have something special?

[fert]

it'll work with any site

[jwk811]

on the site, does that mean i have to install the curl thing.. this doesnt really make much sense to me but ill try to figure it out but still any more help would be incredible

[fert]

If you don't already have it installed you do need to enable the curl extension

I think I might because I'm using godaddy's server and they probably have it.

 

$curl=curl_init("url");

$values=array("ip"=>$_SERVER['REMOTE_ADDR']);
curl_setopt($curl,CURLOPT_POST,true);
curl_setopt($curl,CURLOPT_POSTFIELDS,$values);

$results=curl_exec($curl);

 

Is this all I need to know?

 

Okay so the first line I put the url of the page with the form.

 

Next I have an array with the form's input name with the value, correct?

 

And do I need to change anything with the other two lines?

 

Will that get the country, city, etc.? Where will that information go, into an array?

Godaddy does have curl enabled by default

Okay so the first line I put the url of the page with the form.

right

Next I have an array with the form's input name with the value, correct?

not really

Will that get the country, city, etc.? Where will that information go, into an array?

It'll go into the $_POST array

[jwk811]

Awesome! Thank you so much, your a life saver! 

[jwk811]

For some reason it showed the whole page that had the form on it. Do I need to do something else to get the results?

[jwk811]

nevermind i relized that i was supposed to use the page after the form was submitted lol.. but how can i get the country etc? with the $_POST array? i dont get that

[jwk811]

anyone? fert?

[jwk811]

bump..

[fert]

any information you send to page the with this code will go into the $_POST array

[jwk811]

yeah.. but.. i still dont get it.. okay so $_POST['ip']; will be my ip that i submitted i dont understand how  i can get the country etc.. did you see that site http://www.formyip.com/ipcountry.php when you put an ip in the box and submit it the coutry state and city come up on the next page.. are you saying that the country etc is in the $_POST array? can you be a little more informitive please? thanks.. i am very confused

[fert]

To get the country you'll most likely need regex to parse out the data that you need.

[jwk811]

ok then what did you mean with the "it goes into the $_POST array"

[jwk811]

ive never heard of regex .. could you help me with that?

[fert]

preg_match_all("/<td>(.*?)<\/td>/",$results,$matches);
print_r($matches);

that should get all the data from the tr tags

[jwk811]

i added that to the script and now it just goes to that page and has Array ( [0] => Array ( ) [1] => Array ( ) )  at the bottom..
