Zen does not show search_form

[hygorxaraujo]

When I try to configure the search form in conf.py I get the following error:

Traceback (most recent call last):

The setup:

SEARCH_FORM = """
<!-- DuckDuckGo custom search -->
<form method="get" id="search" action="https://duckduckgo.com/"
 class="navbar-form pull-left">
<input type="hidden" name="sites" value="%s">
<input type="hidden" name="k8" value="#444444">
<input type="hidden" name="k9" value="#D51920">
<input type="hidden" name="kt" value="h">
<input type="text" name="q" maxlength="255"
 placeholder="Search&hellip;" class="span2" style="margin-top: 4px;">
<input type="submit" value="DuckDuckGo Search" style="visibility: hidden;">
</form>
<!-- End of custom search -->
""" % SITE_URL

GLOBAL_CONTEXT = {
    'search_form': SEARCH_FORM,
}

search_form is already available in the global context, don’t add it to GLOBAL_CONTEXT manually.

Ok, thank you for your reply. I got to this configuration by following a sample conf.py (probably outdated). My real problem is that after setting SEARCH_FORM in conf.py the search form is not showing in my theme. Tried with themes zen and zen-forkawesome.

[Kwpolska]

Which conf.py was it?

SEARCH_FORM needs to be used by the theme. The zen themes might not include it in the default configuration, if that’s the case, you’ll need to manually add ${search_form} in the template in the place where you want it to appear.

Sorry, can't find or remember where I saw the conf.py.

From this https://github.com/getnikola/nikola-themes/blob/69deab1c6b2b76c154f9e17fb7ac731a7208e51a/v8/zen/templates/base_header.tmpl#L9 it seems that the search form is used by zen. If I move that piece of code to before ${header.html_navigation_links()} in base.tmpl, the search form is shown, although not properly. https://github.com/getnikola/nikola-themes/blob/69deab1c6b2b76c154f9e17fb7ac731a7208e51a/v8/zen/templates/base.tmpl#L24

Yeah, that’s a bug. The function you’re seeing is not used anywhere. I’ll fix this.

To make the search_form look nice, you will need custom CSS. If you find something that looks good, feel free to contribute this to the zen theme itself.
