我正在使用Goutte,https://github.com/fabpot/goutte,并拥有以下代码,
$client = new Client();
$crawler = $client->request('GET', \Config::get('Eload2::url'));
$form = $crawler->selectButton('Submit')->form();
// add extra fields here
$client->submit($form);
如何在提交之前向表单添加隐藏的输入字段?
我尝试了以下代码,
$domdocument = new \DOMDocument;
$formfield = new InputFormField ($domdocument->createElement('__EVENTTARGET', 'ctl00$ContentPlaceHolder1$DDLTelco'));
$formfield2 = new InputFormField ($domdocument->createElement('__EVENTARGUMENT',''));
$form->set($formfield);
$form->set($formfield2);
但返回以下错误消息
只能从输入或按钮标记(给定__EVENTTARGET)创建InputFormField。
答案 0 :(得分:4)
您正在创建的是:
<__EVENTTARGET>ctl00$ContentPlaceHolder1$DDLTelco</__EVENTTARGET>
<__EVENTARGUMENT />
虽然你想要:
<input name="__EVENTTARGET" value="ctl00$ContentPlaceHolder1$DDLTelco" />
<input name="__EVENTARGUMENT" value="" />
试试这个:
$ff = $domdocument->createElement('input');
$ff->setAttribute('name', '__EVENTTARGET');
$ff->setAttribute('value', 'ctl00$ContentPlaceHolder1$DDLTelco');
$formfield = new InputFormField($ff);
$ff = $domdocument->createElement('input');
$ff->setAttribute('name', '__EVENTTARGET');
$ff->setAttribute('value', '');
$formfield2 = new InputFormField($ff);
