hook_apachesolr_ajax_modules_alter()

If you have a module that defines custom blocks for the apachesolr module, you need to let apachesolr_ajax know about it. (If you don't, apachesolr_ajax won't return the HTML for those blocks in its AJAX response.) Do this by implementing the following hook:

function MYMODULE_apachesolr_ajax_modules_alter(&$modules) {
  $modules[] = 'mymodule';
}

MYTHEME_apachesolr_ajax_js()

If you want to substitute your own JavaScript and CSS files for those used by this module, implement MYTHEME_apachesolr_ajax_js(). Here is the default implementation of theme_apachesolr_ajax_js():

function theme_apachesolr_ajax_js() {
  $head = drupal_get_html_head();
  foreach (array(
    'http://yui.yahooapis.com/2.8.0r4/build/yahoo/yahoo-min.js',
    'http://yui.yahooapis.com/2.8.0r4/build/event/event-min.js',
    'http://yui.yahooapis.com/2.8.0r4/build/history/history-min.js') as $script) {
    if (strpos('<script src="'. $script .'"></script>', $head) === FALSE) {
      drupal_set_html_head('<script src="'. $script .'"></script>');
    }
  }
  drupal_add_js(drupal_get_path('module', 'apachesolr_ajax') .'/apachesolr_ajax.js', 'module', 'footer');
  drupal_add_css(drupal_get_path('module', 'apachesolr_ajax') .'/apachesolr_ajax.css');
}

Note that, if you want to replace some of the functionality within apachesolr_ajax.js, you may do so by overriding its functions. For example, you may override Drupal.apachesolr_ajax.ajax to AJAX-ify links that this module is unaware of.

hook_apachesolr_ajax_enable()

If you want to enable this module on pages other than "search/apachesolr_search", implement this hook, and have it return TRUE for any additional page on which you want to enable this module:

function MYMODULE_apachesolr_ajax_enable() {
  return $_GET['q'] == 'path/on/which/to/enable/search';
}

hook_apachesolr_ajax_disable()

If you want to disable this module on some pages, implement this hook, and have it return TRUE for any page on which you want to disable this module:

function MYMODULE_apachesolr_ajax_disable() {
  return $_GET['q'] == 'path/on/which/to/disable/search';
}

MYTHEME_apachesolr_ajax_yui()

It is unlikely you will ever need to change the markup for Yahoo!'s Browser History Manager, but in case you do, you may change it by implementing MYTHEME_apachesolr_ajax_yui(). Here is the default implementation of theme_apachesolr_ajax_yui():

function theme_apachesolr_ajax_yui($src = '/robots.txt') {
  return '<iframe id="yui-history-iframe" src="'. $src .'"></iframe><input id="yui-history-field" type="hidden">';
}
