# 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 filters 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 `pages` array will only contain results from pages in the `blog` folder.

Search results can be paginated using a plugin such as [Pico-Pagination](https://github.com/rewdy/Pico-Pagination).
The search plugin should be executed before the pagination plugin (execution order is determined by file name).

## 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 loops through the pages and displays
them. Your `search.md` might look like this:

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

Your template file (`search.html` in the above example) should contain something like the following section, which
lists the pages matching the search (substitute `paged_pages` for `pages` if using Pico-Pagination):

```twig
{% for page in pages %}
<div class="search_result">
	<h2><a href="{{ page.url }}">{{ page.title }}</a></h2>
	{% if page.description %}<p>{{ page.description }}</p>{% endif %}
</div>
{% endfor %}
```

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 either in a
template file or on a specific page.

```html
<form id="search_form" action="/search">
    <label for="search_input">Search the site:</label>
    <input type="search" id="search_input" name="q" />
    <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/' + encodeURIComponent(search_terms);
        e.preventDefault();
    });
</script>
```

## 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'];
```
