shearing info from one site to another

[westman 10]

hi all,

I am trying to get a file to run from one of my sites and send the info to my other site.

this is my code...

mysite1.com

<?phpinclude "../connect_to_mysql.php";$sql = mysql_query("SELECT * FROM pics WHERE size= 4 AND pictime != '0' ORDER BY RAND() LIMIT 1" );while($row = mysql_fetch_array($sql)){$picname = $row["id"];}$new_pic = "../images/$picname.gif";?><?phpecho "$new_pic" ?>

mysite2.com

<?php$show_pic = file_get_contents('http://mysite1.com/all/rand.php');?><?phpecho "$show_pic" ?>

at you can see it is not working and I don't know why.

any help?

I don't think that's possible because of security reasons unless both websites are hosted from same server. //Prob misunderstood post but

 

$new_pic = "../images/$picname.gif"; <!-- this is only text, not image -->echo "$new_pic" <!-- this ain't closed -->

 

Have you tested your code?

Mudsaf is correct that your website host has probably disabled this function. If you can call a script on one of your websites from a different website then it means others can do so to - and you don't want that to happen.

 

You should google for cURL and look at some of the tutorials available. You might be able to do it that way instead, although some hosts disable this as well.

The code I wrote is just a simple example of my true code I have.

 

how do I get my code working with cURL?

[westman 10]

any help?

Have you researched cURL? The documentation is online. You should find several examples also.

[westman 10]

I have researched cURL but got nowhere, could you provide a link to an example that is related to what i am looking for?

[justsomeguy 1,135]

There are examples everywhere. This is the second result for "php curl download":

then show us what you tried and what you got stuck on.

[westman 10]

hi,

I looked up the link...

http://davidwalsh.name/curl-download

and man I tried for 2 days, but I just could not get my head around it

 

so this is my code...

mysite1.com (example code)

<?phpinclude "../connect_to_mysql.php";$sql = mysql_query("SELECT * FROM pics WHERE size= 4 AND pictime != '0' ORDER BY RAND() LIMIT 1" );while($row = mysql_fetch_array($sql)){$picname = $row["id"];}$check_new_pic = "../images/$picname.gif";if (file_exists($check_new_pic)) {$pic = "<a href="#" target="_blank"><img src="$check_new_pic" height="300" width="200px" style="border:0;" /></a>";?><?phpecho "$pic";?>

mysite2.com (true code)

<?phpfunction get_data($url) {$ch = curl_init();$timeout = 5;curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);$data = curl_exec($ch);curl_close($ch);return $data;}$returned_content = get_data('http://mysite1.com/all/rand.php');?>

as you can see I am trying to get 1 random image from one site to anotherlol google does it every day with their ads, why is it so hard?

[westman 10]

ok people,

I got it working with...

$ch = curl_init();curl_setopt($ch, CURLOPT_URL,'http://mysite1.com/all/rand.php');curl_setopt($ch, CURLOPT_HEADER, false);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);$xml_language = curl_exec($ch);curl_close($ch);echo $xml_language;

now my last question is how do I stop people hacking me with this code and can someone explain line for line how my code works, that would be a big help for days to come.

 

thanks in advance.

[justsomeguy 1,135]

That isn't code to protect against a hacker, I don't know what you're asking there. If you want to find out how cURL works, look up the documentation. Look up the reference for any function you don't understand like curl_init or curl_setopt.

[westman 10]

I looked it up and understand it now but how do I stop this code been used by someone I don't know (hacker)?

[justsomeguy 1,135]

If it's online then anyone can reach it. You can add authentication checking or something like that to restrict access only to people who have logged in. I don't really see how a hacker would use that code to attack your server though.
