Post to external site with curl
Hi, i am trying to post something to external site, and i found out best way to do this is cURL.
Here is my code:
PHP Code:
<html>
<body>
<?php
include('simple_html_dom.php');
$url = "example.com";
$a = "744bhz";
$html = new simple_html_dom();
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_USERAGENT,
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'pregnr=' . urlencode($a));
$result = curl_exec($ch);
echo $result;
curl_close($ch);
?>
</body>
</html>
Problem is it only loads me blank page nothing else, i have error reporting enabled in php.ini, but no errors, just blank page.
Site html is like this:
Code:
<FORM NAME="kindlustuskate" METHOD="POST" ACTION="SYSADM.LK_INFOKESKUS_PKT.kindlustuskate">
<input type="hidden" name="plang" value="ENG">
<TABLE width=100% CELLPADDING=3 CELLSPACING=0 BORDER=0>
<tr>
<td align="right" width=350>Registration plate number</td>
<td width=10> </td>
<td><input type="text" name="pregnr" value=""> <font size="1">For example 000XXX</font></td>
</tr>
<tr>
<td align="right" width=350>Vehicle VIN code</td>
<td width=10> </td>
<td><input type=text name=pvin value=> <font size=1>For example 45XXXXXXXXXXXXXXXXX65</font></td>
</tr>
<tr>
<td align="right" width=350>Insurance policy number</td>
<td width=10> </td>
<td><input type=text name=ppolnr value=""> <font size=1>For Example E0000000T</font></td>
</tr>
<tr>
<td align="right" width=350>Date of validity</td>
<td width=10> </td>
<td><input type=text name=pkuup value=""> <font size=1>dd.mm.yyyy</font></td>
</tr>
<tr>
<td align=right valign=top>Area of validity</td>
<td align=right valign=top> </td>
<td align=left valign=middle>
<input type=radio name="pala" checked value="1">European Economic Area (EEA) member state or Switzerland<br>
<input type="radio" name="pala" value="2">Green card system country<br>
</td></tr>
<tr>
<td align="right" width=350> </td>
<td width=10> </td>
<td><input type="submit" name="potsi" value="Find"></td>
</tr>
</table>
</form>
Site is https, i dont know if this matters or not, but ihave set sssl verify false in curl anyway.
I have messed with this for many hours, any ideas?

Why do people just automatically assume every call they makes succeeds without checking?
php Code:
 Original
- php Code |
|
|
|
$result = curl_exec($ch); if ($result === FALSE) { echo ("ERROR: " . curl_error ($ch)); } curl_close($ch);
If the error you're getting is
Code:
ERROR: error:14077417:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert illegal parameter
then add
php Code:
| Original
- php Code |
|
|
|
curl_setopt($ch, CURLOPT_SSLVERSION, 3);

And you'll have to pass more than just the license plate number otherwise the form just redisplays itself.

But in original site i can just input license plate and click submit, why cant i do this with curl?
vs.lkf.ee/pls/xlk/SYSADM.LK_INFOKESKUS_PKT.kindlustuskate
Just add https in front of it, i cant post live links here.
For example 217thd.

Because not entering values is not the same as not passing them along at all.

But how can i pass empty value with curl, i tried "0" but that wont work. It fills form with 0.
Maybe
PHP Code:
curl_setopt($ch, CURLOPT_POSTFIELDS, 'formname=');

I tried with
Code:
curl_setopt($ch, CURLOPT_POSTFIELDS, 'formname=');
Nothing, it just loads the site as anything is not submited, anyone have any ideas?
PHP Code:
<html>
<body>
<?php
include('simple_html_dom.php');
$url = "https://vs.lkf.ee/pls/xlk/SYSADM.LK_INFOKESKUS_PKT.kindlustuskate?plang=EST";
$a = "744bhz";
$html = new simple_html_dom();
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_USERAGENT,
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'pregnr=' . urlencode($a));
curl_setopt($ch, CURLOPT_POSTFIELDS, 'pvin=');
curl_setopt($ch, CURLOPT_POSTFIELDS, 'ppolnr=');
curl_setopt($ch, CURLOPT_POSTFIELDS, 'pkuup=');
$result = curl_exec($ch);
if ($result === FALSE)
{
echo ("ERROR: " . curl_error($ch));
}
curl_close($ch);
echo $result;
?>
</body>
</html>

All those curl_setopt()s you have are overwriting each other.
Give it an array of the values you want to send.

Thanks for the hint, i made an array with values, but i am still not sure if passing empty data is done right, anyway still no success, script still loads site as no data has been entered.
Code with changes:
PHP Code:
<html>
<body>
<?php
include('simple_html_dom.php');
$url = "https://vs.lkf.ee/pls/xlk/SYSADM.LK_INFOKESKUS_PKT.kindlustuskate?plang=EST";
$data = array('pregnr' => '217thd', 'pvin' => '', 'ppolnr' => '', 'pkuup' => '' );
$html = new simple_html_dom();
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_USERAGENT,
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
if ($result === FALSE)
{
echo ("ERROR: " . curl_error($ch));
}
curl_close($ch);
echo $result;
?>
</body>
</html>

That's right, but you still haven't included all the form fields.
Example: when you click a named submit button, its name and value are included in the request.
