I want to use Acymailing Joomla! component installed at example.com/mailer to manage subscriptions from non Joomla site on example.com
In that case I have simple script
$(function () {
$('form').on('submit', function (e) {
e.preventDefault();
$.ajax({
type: 'post',
url: 'https://example.com/mailer/index.php?option=com_acymailing&ctrl=sub',
data: $('form').serialize(),
success: function () {
swal('Great success!');
}
});
});
});
and form
<form class="form-inline" action="https://example.com/mailer/index.php?option=com_acymailing&ctrl=sub" method="post">
<div class="form-group">
<label class="sr-only" for="user_name">Email address</label>
<input id="user_name" type="text" name="user[name]" value="" class="form-control" placeholder="Email">
</div>
<div class="form-group">
<label class="sr-only" for="user_email">Password</label>
<input id="user_email" type="text" name="user[email]" value="" class="form-control" placeholder="Password">
</div>
<button type="submit" class="btn btn-default">Sign Up!</button>
<input type="hidden" name="user[html]" value="1" />
<input type="hidden" name="acyformname" value="formAcymailing1" />
<input type="hidden" name="ctrl" value="sub"/>
<input type="hidden" name="task" value="optin"/>
<input type="hidden" name="redirect" value="https://example.com"/>
<input type="hidden" name="option" value="com_acymailing"/>
<input type="hidden" name="visiblelists" value=""/>
<input type="hidden" name="hiddenlists" value="1"/>
</form>
Everything works fine except success, error states...
Joomla Acymailing have sub.php file to handle ajax responses
if($config->get('subscription_message',1) || $ajax){
if($allowSubscriptionModifications){
if($statusAdd == 2){
if($userClass->confirmationSentSuccess){
$msg = 'CONFIRMATION_SENT';
$code = 2;
$msgtype = 'success';
}else{
$msg = $userClass->confirmationSentError;
$code = 7;
$msgtype = 'error';
}
}else{
if($insertMessage){
$msg = 'SUBSCRIPTION_OK';
$code = 3;
$msgtype = 'success';
}elseif($updateMessage){
$msg = 'SUBSCRIPTION_UPDATED_OK';
$code = 4;
$msgtype = 'success';
}else{
$msg = 'ALREADY_SUBSCRIBED';
$code = 5;
$msgtype = 'success';
}
}
}else{
if($modifySubscriptionSuccess){
$msg = 'IDENTIFICATION_SENT';
$code = 6;
$msgtype = 'warning';
}else{
$msg = $modifySubscriptionError;
$code = 8;
$msgtype = 'error';
}
}
if($msg == strtoupper($msg)){
$source = acymailing_getVar('cmd', 'acy_source');
if(strpos($source, 'module_') !== false){
$moduleId = '_'.strtoupper($source);
if(acymailing_translation($msg.$moduleId) != $msg.$moduleId) $msg = $msg.$moduleId;
}
$msg = acymailing_translation($msg);
}
$replace = array();
$replace['{list:name}'] = '';
foreach($myuser as $oneProp => $oneVal){
$replace['{user:'.$oneProp.'}'] = $oneVal;
}
$msg = str_replace(array_keys($replace),$replace,$msg);
if($config->get('redirect_tags', 0) == 1) $redirectUrl = str_replace(array_keys($replace),$replace,$redirectUrl);
if($ajax){
$msg = str_replace(array("\n","\r",'"','\\'),array(' ',' ',"'",'\\\\'),$msg);
echo '{"message":"'.$msg.'","type":"'.($msgtype == 'warning' ? 'success' : $msgtype).'","code":"'.$code.'"}';
}elseif(empty($redirectUrl)){
acymailing_enqueueMessage($msg,$msgtype == 'success' ? 'info' : $msgtype);
}else{
if(strlen($msg)>0){
if($msgtype == 'success') acymailing_enqueueMessage($msg);
elseif($msgtype == 'warning') acymailing_enqueueMessage($msg,'notice');
else acymailing_enqueueMessage($msg,'error');
}
}
}
And JSON looks like on Joomla side registration to the same form by index.php?option=com_acymailing&ctrl=sub
message Subscribe confirmed
type success
code 3
{"message":"Subscribe confirmed","type":"success","code":"3"}
The question is: how to obtain that submission statuses success, error, already submbited etc on external submission form (at example.com page)?
I don't feel your ajax had issues, what i can see from the Joomla php code, everytime when you request that joomla URL you will always get a response header status code as 200, so your javascript will always land on success block of ajax code, returning with some json based message, when i checked the joomla acymaling (version 5.8.1 for joomla 3.8.3) code for that controller, i saw on line number 74 they are checking if the request is made using ajax, but missing Access-Control-Allow-Origin in php header which will restrict your outside call so you can replace this if condition from :
if($ajax){
@ob_end_clean();
header("Content-type:text/html; charset=utf-8");
}
to
if($ajax){
@ob_end_clean();
header("Content-type:text/html; charset=utf-8");
header("Access-Control-Allow-Origin: *");
}
so to allow calls from any other domain as well, but do remember this can also cause vulnerabilities to you joomla code. also you need to change your HTML form as well add one more hidden field in your HTML :
<input type="hidden" name="ajax" value="1" />
so to allow ajax request by your joomla controller file.
now in your success block of ajax you can make a check something like this :
success:function(data, status, xhr){
var json = $.parseJSON(data);
swal(json.message, json.type);
}
I hope this will help you in acomplishing what you want to, Happy coding.
