php - Pregmatch form fields that are not hidden, retrieve only names -

i'm trying scan form, , pull out fields not type="hidden" , retrieve name="" value, i'm using

@<input.*?>@

which retrieves following me,

( [0] => array     (         [0] => <input type="email" id="contact0email" name="email" class="field" onfocus="if ($(this).val() == $(this).attr('title')) { $(this).val('') }" onblur="if ($(this).val()=='') { $(this).val($(this).attr('title'));}" title="enter valid email here" value="enter valid email here">         [1] => <input type="submit" class="submit" value="get instant access">     ) 

however not need code, i'd have scan further need, suggest regular expression should use need? in example there no hidden fields, there may in others need run for.

here quick , dirty solution you:

$string = '<form name="input" action="html_form_action.asp" method="get"> <input type="hidden" name="foo" value="123"/> username: <input type="text" name="user" value="ralph"> pass: <input type="text" name="pass"> <input type="submit" value="submit"> </form>';  $doc = new domdocument(); $doc->loadhtml($string);  $input = $doc->getelementsbytagname('input');  ($i = 0; $i < $input->length; $i++) {      $el = $input->item($i);      if ($el->getattribute('type') === 'hidden'       || $el->getattribute('type') === 'submit') continue;      echo $el->getattribute('name')         .':'.$el->getattribute('value')."\n";  }
