[MODx] 6. Cache '!' with login package

1. Install login package.

2. Create a Template called 'login':

[[!Login? 
    &loginResourceId=`13`  // means after login, redirect resource 13 page, in our case, redirect to self
]]
<h2>Register</h2>
 
[[!Register?
    &submitVar=`registerbtn`
    &activationResourceId=`12`
    &activationEmailTpl=`myActivationEmailTpl`
    &activationEmailSubject=`Thanks for Registering!`
    &submittedResourceId=`5`
    &usergroups=`Marketing,Research`
    &validate=`nospam:blank,
  username:required:minLength=^6^,
  password:required:minLength=^6^,
  password_confirm:password_confirm=^password^,
  fullname:required,
  email:required:email`
    &placeholderPrefix=`reg.`
]]
 
<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]]" />
 
        <label for="username">[[%register.username? &namespace=`login` &topic=`register`]]
            <span class="error">[[!+reg.error.username]]</span>
        </label>
        <input type="text" name="username" id="username" value="[[!+reg.username]]" />
 
        <label for="password">[[%register.password]]
            <span class="error">[[!+reg.error.password]]</span>
        </label>
        <input type="password" name="password" id="password" value="[[!+reg.password]]" />
 
        <label for="password_confirm">[[%register.password_confirm]]
            <span class="error">[[!+reg.error.password_confirm]]</span>
        </label>
        <input type="password" name="password_confirm" id="password_confirm" value="[[!+reg.password_confirm]]" />
 
        <label for="fullname">[[%register.fullname]]
            <span class="error">[[!+reg.error.fullname]]</span>
        </label>
        <input type="text" name="fullname" id="fullname" value="[[!+reg.fullname]]" />
 
        <label for="email">[[%register.email]]
            <span class="error">[[!+reg.error.email]]</span>
        </label>
        <input type="text" name="email" id="email" value="[[!+reg.email]]" />
 
        <br class="clear" />
 
        <div class="form-buttons">
            <input type="submit" name="registerbtn" value="Register" />
        </div>
    </form>
</div>

[[!Profile]]
 
<p>Username: [[+username]]</p>
<p>Email: [[+email]]</p>

In the bottom, we call the [[!Profile]] snippet without cache. So every time, we logout, the profile will be clear up.  

If we call [[Profile]], then everytime, we logout, the username and email are still there.

Caching

In Evolution, Snippets that need to be processed with each request should be on an uncached page or the Snippet itself should be called uncached: [!snippet!]

In Revolution, any tag can be called uncached by inserting an exclamation point immediately after the double-bracket: [[!snippet]], [[!$chunk]], [[!+placeholder]], [[!*template_var]], etc.
