php - Crawler + Guzzle: Accessing to form -

i using php guzzle client grab website, , process symfony 2.1 crawler

i trying access form....for example test form here http://de.selfhtml.org/javascript/objekte/anzeige/forms_method.htm

$url = 'http://de.selfhtml.org/javascript/objekte/anzeige/forms_method.htm'; $client = new client($url);  $request = $client->get(); $request->getcurloptions()->set(curlopt_ssl_verifyhost, false); $request->getcurloptions()->set(curlopt_ssl_verifypeer, false); $response = $request->send(); $body = $response->getbody(true); $crawler = new crawler($body); $filter = $crawler->selectbutton('submit')->form(); var_dump($filter);die(); 

but exception:

the current node list empty.

so kind of lost, on how access form

try using goutte, screen scraping , web crawling library build on top of tools using (guzzle, symfony2 crawler). see github repo more info.

your code using goutte

<?php use goutte\client;  $url = 'http://de.selfhtml.org/javascript/objekte/anzeige/forms_method.htm'; $client = new client();  $crawler = $client->request('get', $url); $form = $crawler->selectbutton('submit')->form(); $crawler = $client->submit($form, array(     'username' => 'myuser', // assuming submitting login form      'password' => 'p@s5' )); var_dump($crawler->count()); echo $crawler->html(); echo $crawler->text(); 

if need setup curl options can way:

<?php $url = 'http://de.selfhtml.org/javascript/objekte/anzeige/forms_method.htm'; $client = new client(); $guzzle = $client->getclient(); $guzzle->setconfig(      array(         'curl.curlopt_ssl_verifyhost' => false,         'curl.curlopt_ssl_verifypeer' => false,     )); $client->setclient($guzzle); // ... 

update:

when using domcrawler times same error. of time because i'm not selecting correct element in page, or because doesn't exist. try instead of using:

$crawler->selectbutton('submit')->form(); 

do following:

$form = $crawler->filter('#signin_button')->form(); 

where using filter method element id if has 1 '#signin_button' or class '.signin_button'. filter method requires the cssselector component.

also debug form printing out html (echo $crawler->html();) , ensuring on right page.
