Using IF Logic and Settings in a Template

I am creating a simple module that will display a form field, or not, based on a settings file managed from the modules page in admin. Basically an on/off toggle of a form field. I would like to be able to test if this setting has been set and only display it's associated form field if it has been set.

If I look at register.tpl I see a block that looks like:

{IF ERROR}
<div class="PhorumUserError">{ERROR}</div>
{/IF}

I would like to do something like this (pseudo-code):

{IF my_mod form field is true}
{HOOK tpl_my_mod_field_hook}
{/IF}

I've tried different variations of the above but am obvious not understanding something.

What is the correct way to check if the value has been set in a template and display my field?

Thanks!

{IF my_mod form field}
{HOOK tpl_my_mod_field_hook}
{/IF}

You can only use the {IF ...} .. {/IF} syntax in case the variable that you check is in $PHORUM["DATA"]. If you are using the standard way for storing module settings (using the phorum_db_update_settings() function), then the settings will be in $PHORUM["mod_yourmod"] and $PHORUM["SETTINGS"]["mod_yourmod"] though. As a result of this, you cannot access the setting within an {IF ...} statement.

There are two things you can do.

1) revert to plain PHP code in the template:

Template code:

   <?php
   if (isset($PHORUM["mod_yourmod"]["some_setting"]) &&
      $PHORUM["mod_my_mod"]["show_form_field"] == true) {
      ?>
      FORM FIELD CODE GOES HERE
      <?php
   }
   ?>

2) transfer the setting to $PHORUM["DATA"] from a hook in your module.

Module code:

   global $PHORUM;
   $PHORUM["DATA"]["my_mod_field"] = $PHORUM["mod_my_mod"]["show_form_field"];

Template code:

   {IF my_mod_field}
      FORM FIELD CODE GOES HERE
   {/IF}
