Need help with making a php form

I have a php curl script that will check if a site is supported by my site. All I need to do is to enter the url and upload it to the server.

But now I want to make it into form. Like, entering a url and submit it will do the same job. This would be much hassle free as I don't have to reupload edited file over and over again.

Can anyone tell me where I could find reference to do this?

What I want to achieve:
Enter url to check
<form> <submit>

...process

If not success:
The domain <domain> is currently not supported.

If success:
Congratulation, <domain> is supported.

Can anyone help me by telling me how can I do this?




Existing code:

<?php
	$timeout = 5;
	$desc = 'Site Compatibility Check';
	$file_loc = 'testfile.pdf';

    	$url = 'http://www.merryone.com/';
	
	$postcontent= array();
	$postcontent['file_0']='@'.$file_loc;
	$postcontent['upload_type']='file';
	$postcontent['file_0_descr']= $desc;
	$postcontent['file_0_public']= 1;
	$postcontent['tos']= 1;
	$upload_id=(96).time();
	$ch = curl_init ();
	
	curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Expect:'));
	curl_setopt ($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)');
	curl_setopt ($ch, CURLOPT_REFERER, $url);
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
	
	curl_setopt ($ch, CURLOPT_URL, $url);
	$result = curl_exec ($ch);
	preg_match('/enctype="multipart\/form-data"[^>]+action="(.*?)\/cgi-bin\/upload\.cgi/is',$result,$match);
    
	$posturl = $match[1];
	curl_setopt ($ch, CURLOPT_URL, $posturl.'/cgi-bin/upload.cgi?upload_id='.$upload_id.'&js_on=1&utype=anon&upload_type=file');
	
	curl_setopt ($ch, CURLOPT_POST, 1);
    curl_setopt ($ch, CURLOPT_POSTFIELDS, $postcontent);
	$result = curl_exec ($ch);
	preg_match('/name=\'fn\'>(.+?)</is',$result,$dll);

	if($dll[1])
	{
		$postcontent='fn='.$dll[1].'&st=OK&op=upload_result';
	
		curl_setopt ($ch, CURLOPT_URL,$url);
		curl_setopt ($ch, CURLOPT_POSTFIELDS, $postcontent);
		$result = curl_exec ($ch);
		preg_match('/<input[^>]+onFocus="copy\(this\);" value="(http:\/\/[^"]+)/is',$result,$dll);
	}
	
	curl_close ($ch);
	
	if($dll[1])
	{
		echo $dll[1];
	}
	else
		echo 'This site is not supported!';

?>

Can anyone help?

 

Emm not sure if this is what you want ? do you have a sample url of a matching site ?

$url = $_GET['url'];

PHP:

and add a form after ?> like this

?>
<form>
<input type="text" name="url">
<input type="submit">
</form>

PHP:

 

Ah, $_GET. I used POST.
No wonder any url came out not supported.

Now I got it working.
Thank you. Rep is coming your way

 

Great. Now the form is working.

I'm reading a tutorial to adapt this form into AJAX.
So far, there is no progress of how to make this work.

The tutorial I read is from HERE.
It's actually a contact form but I figure it could also be used for a simple form as well. Correct me if I'm wrong.

Appreciate if anyone can teach me this too

Thanks.
