# Pico-Search

A plugin for the flat file CMS [Pico](https://github.com/picocms/Pico). Allows you to create a very basic search form
that searches through titles and content of your pages. The search results page can filter the `pages` array to only
contain pages matching the search terms.

You can optionally scope the search to only get results from within a certain folder. For example, on the page
`yoursite.com/blog/search/foobar`, the filtered array will only contain results from pages in the `blog` folder.

## Breaking changes as of January 2020

If you were using an earlier version of the plugin, the current version will not work as before. Previously the `pages`
array was directly modified to filter and sort search results. This approach was not compatible with other Pico
plugins and themes which depend on the `pages` array to contain all pages.

Instead, this plugin now makes a Twig filter called `apply_search` available, which can be used in your templates to
filter the `pages` array on demand: `{% set search_results = pages|apply_search %}`. This also makes it possible to
combine with other plugins that behave similarly: `{% set results = pages|apply_search|paginate %}`

## Installation

- **Copy the file `40-PicoSearch.php` to the `plugins` sub-folder of your Pico installation directory.**
- **Add a file named `search.md` to your content root or the sub-folder you want to make searchable.**
  This is your search results page. You can leave it empty of content, but set the `Template` meta tag to a template
  that displays the filtered pages. Your `search.md` might look like this:

```
  /*
  Title: Search results
  Template: search
  */
  ```

- **Add a template file with the name defined in `search.md`.**
  Your template file (`search.twig` in the above example) should contain something like the following section, which
  lists the pages matching the search:

```twig
  {% if search_terms %}
    <div class="SearchResults">
        {% set search_results = pages|apply_search %}
        {% if search_results %}
            <h2>Search results for {{ search_terms|e('html') }}</h2>
            {% for page in search_results %}
                <div class="SearchResult">
                    <h3><a href="{{ page.url }}">{{ page.title }}</a></h3>
                    {% if page.description %}<p>{{ page.description }}</p>{% endif %}
                </div>
            {% endfor %}
        {% else %}
            <p>No results found for {{ search_terms|e('html') }}.</p>
        {% endif %}
    </div>
  {% endif %}
  ```

The `apply_search` filter takes any search terms for the current page and filters the specified array
  by them, as well as sorting them by relevance.

If you simply want to make your search results page look like your standard page, you may want to edit your theme's `index.twig` file and change `{{ content }}` to `{% block content %} {{ content }} {% endblock %}`. This allows you to extend this base template and reuse all the other parts of it in your search results template:

```twig
  {% extends "index.twig" %}

{% block content %}
      {{ parent() }}

<div class="SearchResults">
          
      </div>
  {% endblock content %}
  ```

Now, you should be able to visit for example `yoursite.com/search/foobar` (adjust path accordingly if putting search.md
in a sub-folder) and see the search results for "foobar" listed.

## The search form

How to design your search form is up to you, but here's a very rudimentary example which you can put in a
template file:

```html
<form id="search_form" action="{{ "search"|link }}">
    <label for="search_input">Search the site:</label>
    <input type="search" id="search_input" name="q" value="{{ search_terms|e('html_attr') }}" />
    <input type="submit" value="Search" />
</form>
<script type="text/javascript">
    // Intercept form submit and go to the search results page directly, avoiding a redirect
    document.getElementById('search_form').addEventListener('submit', function (e) {
        var search_terms = document.getElementById('search_input').value;
        location.href = '{{ "search"|link }}/' + encodeURIComponent(search_terms);
        e.preventDefault();
    });
</script>
```

If you want to put it in a content file, you'll have to adjust the template variables accordingly, ie. instead of `{{ "search"|link }}` you'd use something like `%base_url%?search`.

## Configuration options

You can exclude certain pages from being included in the search results by using the configuration option `search_excludes`.
Set it to an array of pages you'd like to exclude, where each page is specified as its path relative to the content root:

```php
$config['search_excludes'] = ['search', 'some/other/page'];
```
