Time for action - creating the search form

  1. Create a script /path/to/webroot/feeds/search.php with the following content:
    <?php
/**
* File: /path/to/webroot/feeds/search.php
*/
include('init.php'),
// Get all the categories and their ids
// This will be used to build the categories filter drop down
$query = "SELECT id, name FROM categories ORDER BY name";
foreach ($dbh->query($query) as $row) {
$viewVars['cat_list'][$row['id']] = $row['name'];
}
// Render the page
render('search'),
  2. Create the view for the search page at /path/to/webroot/feeds/views/search.thtml:

    Time for action - creating the search form

What just happened?

We created a basic form to specify the search phrase, author name, and select multiple categories. We built the categories select box using the category labels we have in our database table.

Search will be performed against different fields as given next:

  • Search for: Required. Full-text search against and description of feed items.
  • Author: Optional. Full-text search against author name in addition to the above.
  • Category: Optional. Filter results by the selected categories in addition to the above.

Perform the search query

The form we created does nothing but render different fields. Let's give it some life by adding the code that performs a search against the Sphinx index and displays the results. We will use a PHP implementation of the Sphinx Client API to perform search queries.
