posting to a form with image verification with CURL

[dsaba]

this code keeps posting the wrong image verification code, to the form, because when it loads the form again to post the code that I retrieved the image verification code, is now changed

 

How can I do this successfully with curl? If you have any experience with using curl functions in php you CAN help me on this one.

 

<?php
if (!isset($_GET['code'])) {
$formurl = 'http://p2mcity.freehostia.com/mh-db.php?add=problem';

$curlit = curl_init();	
curl_setopt($curlit, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curlit, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curlit, CURLOPT_URL, $formurl);
$result = curl_exec($curlit);
$oneArray = explode('<td height="14"><input name="captcha" type="text" size="6" maxlength="5" />', $result);
$twoArray = explode('</td>', $oneArray[1]);
$image = $twoArray[0];	  
echo $image; //this echoes back the image for image verification from the html form

echo '<form action="imagecurl.php" method="get" name="whatever">
Type in the code: <input name="code" type="text" size="6" maxlength="5" /><input type="submit" value="Submit"/></form>';

} else {
$posturl = 'http://p2mcity.freehostia.com/mh-db.php';
$curlit = curl_init();	
curl_setopt($curlit, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curlit, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curlit, CURLOPT_URL, $posturl);
curl_setopt ($curlit, CURLOPT_POSTFIELDS, "title=whatever&description=whatever&mhversion=123&nickname=whatever&[email protected]&livecontact=whatever&service=whatever&captcha=".$_GET['code']."&add=suggestion&Submit33=Submit");	
$result = curl_exec($curlit);	
echo $result;

}
?>

 

 

here is the live script where I uploaded and tested it with:

I'm new to PHP and am unsure what CURL is, but just so you have something to look into if you would like to give your brain a break.

 

Here's what I believe may be an alternative:

thanks for reading

 

but you've misread my question, my question is not about how to create an image for verification

 

but on how to use CURL to post to a form that requires a code to be typed for image verification

 

curl is a set of functions compiled into php that allows you to do remote http connections, including posting to forms

 

the problem with my current algorithim in doing this is that, first i load the page once to grab teh image, spit it back to my script and then I submit the code into a form, then i load the form AGAIN to post the information with the code i just typed, the problem is that the second time I load the form a NEW image verification has been generated, so i need to create some kind of algorithim to where i can retrieve the image, send the image back to my script, and post the new data to the form with the code, all in ONE page load

 

thats what I need help figuring out, the above code is the only alogorithim i know of, I need phpfreaks help in showing me the correct way to do what I want to do, because obviously my method is not working
