Cannot trigger ClassExtender posthook from Login

Support
1

Hello,

I’m currently trying to implement a front-end user management in MODX.

All works fine except for new users registration. For this I use Login + Bob Ray’s ClassExtender to manage additional data at user level.

[[!Register?
    &submitVar=`loginRegisterBtn`
    &activation=`0`
    &usergroupsField=`usrgrp`
    &validate=`nospam:blank,
  username:required:minLength=^6^,
  password:required:minLength=^6^,
  password_confirm:password_confirm=^password^,
  fullname:required,
  email:required:email`
    &submittedResourceId=`127`
    &useExtended=`0`
	&placeholderPrefix=`reg.`
    &postHooks=`ExtUserRegisterPosthook`
]]

<div class="register">
    <div class="registerMessage">[[!+reg.error.message]]</div>

    <form class="form" action="[[~[[*id]]]]" method="post">
        <input type="hidden" name="nospam" value="[[!+reg.nospam]]" />

       ...

        <div class="form-buttons">
            <input type="submit" name="loginRegisterBtn" value="Register" />
        </div>
    </form>
</div>

The issue is that &postHooks doesn’t seem to trigger anything (I put some debug function inside ExtUserRegisterPosthook, and it is not called by Login).

I found on a previous topic that form button name and values could be an issue for ExtUserRegisterPosthook, but my form configuration seems quite aligned with the code of the snippet:

$submission = isset($_POST[‘loginRegisterBtn’]) && ($_POST[‘loginRegisterBtn’] == ‘Register’);

So, if anyone has any idea I would appreciate!
