New subject: [SOLVED] Re: Form submit via ajax and validate

5 Jun 2012


      Hi all. I have a custom form, and I need to send it via ajax. I know that exist ['#ajax'] so  this is my form:
$form = array();
    $form['name'] = array(
    	'#type'=> 'textfield',
    	'#size' => 30,
    	'#title'=> 'Nome',
    	'#weight' => "float up"
);	
    $form['email'] = array(
    	'#type'=> 'textfield',
    	'#size' => 30,
    	'#title'=> 'Email',
    );	
    $form['phone'] = array(
    	'#type'=> 'textfield',
    	'#size' => 30,
    	'#title'=> 'Telefono',
    );	
    $form['msg'] = array(
    	'#type'=> 'textarea',
    	'#size' => 30,
    	'#rows' => 3,
    	'#title'=> 'msg',
    );	
    
    $form['my_captcha_element'] = array(
        '#type' => 'captcha',
        '#captcha_type' => 'captcha/Math',
    );
$form['invia'] = array(
    	'#type'=> 'submit',
    	'#value' => 'Invia',
    	'#weight' => 40,
    	'#ajax' => array(
    		'callback' => 'xblock_form_contatto_ad_form_submit',
    		'wrapper' => 'form_submit',
    		),
    	
    );	
    
    $form['markup'] = array(
    	'#prefix' => '<div id="form_submit">',
    	'#suffix' => '</div>',
    	'#markup' => '',
    );
This is my callback function: 
function xblock_form_contatto_ad_form_submit($form, $fs) {
  $errors = form_get_errors();
    if ($errors) {
    	$out ="<span style='color: red;'>";
        foreach ($errors as $k => $v) {
    	    $out .= $v."<br>";
        }
        $out .="</span>";
        return $out;
    }
$body = theme('xblock_form_contatto_ad_form',array('data' => $fs['values']));
  mail("michel@ziobuddalabs.it","Contatto da form",$body);
  return "<span style='color: green;'>Invio effettuato</span>";
}
My problem is the form validation: I have a captcha and I do not insert nothing so captcha validate return an error, and I can see it in the json "command" result, but when I reinsert the captcha with correct "entry" I get this:
0: {command:settings, settings:{basePath:/, pathPrefix:,…}, merge:true}
1: {command:insert, method:null, selector:null,…}
command: "insert"
data: "<span style='color: red;'>The answer you entered for the CAPTCHA was not correct.<br></span>"
method: null
selector: null
settings: null
2: {command:insert, method:prepend, selector:null,…}
command: "insert"
data: "<div class="messages error">↵<h2 class="element-invisible">Error message</h2>↵ <ul>↵  <li>CAPTCHA session reuse attack detected.</li>↵  <li>The answer you entered for the CAPTCHA was not correct.</li>↵ </ul>↵</div>↵"
method: "prepend"
selector: null
settings: null
"CAPTCHA session reuse attack detected" ???
