Drupal 7 Views 3 exposed filter preselected

Question

I'm having a bit of a hard time configuring a preselected exposed filter on views.

I have a View (mysite.com/view-path) with an exposed filter as a select list with options:

Option 1
Option 2
Option 3

I want to be able to access the view with a preselected option in the exposed filter from another page (mysite.com/page) with a link like so (mysite.com/view-path?option=1)

Right now i've made a form alter on the exposed view filter with this:

if (!empty($_GET['option'])) {
   $form_state['input']['field_option_tid'] = $_GET['option'];
}

The problem is that this works, but when i try to click the select list and change the value to Option 2 for example, it will revert back to Option 1.

Answer 1

Use a custom module for this

function MYMODULE_form_views_exposed_form_alter(&$form, &$form_state) {
  if (!isset($form_state['view']->exposed_input['<filter_field>'])) {
    // OK to set the default value
    $form_state['input']['<filter_field>'] = '<new_default_value>';
  }
}

Where filter_field is the name of the exposed filter and new_default_value is the key of the value you want as the default.

Got the idea from this article

Answer 2

SOLVED IT!

Got it to work by not doing any form_alter, instead i reconstructed the URL with the argument that sends me to the page view, with exactly the field_filter ID

So, basically, when you use exposed filters on a view, it automatically changes the url to something like mysite.com/view?field_filter=1, i tried to use mysite.com/view?option=1 and then make a form alter to rewrite the $form_state[input], but this will always overwrite the user POST.

Answer 3

Working with POST values didn't work on my form. And 4life's answer was close, but in the end this is the approach that worked for me complete with pretty paths:

    function MYMODULE_form_views_exposed_form_alter(&$form, &$form_state, $form_id) {
      $current_path = current_path();
      $path_array = explode('/', $current_path);
        if(isset($path_array[1])){
          switch ($path_array[1]) {
            case 'new_value':
              unset($form_state['input']['field_nameoffield']);
              $form_state['input']['field_nameoffield']['new_value']= 'new_value';
              break;

            case 'new_value_2':
              unset($form_state['input']['field_nameoffield']);
              $form_state['input']['field_nameoffield']['new_value_2']= 'new_value_2';
              break;
          }
        }
     }

Answer 4

As 4life specified in his answer, do this in a custom module in hook_form_FORM_ID_alter(). The only difference is that you should set the $form element's #default_value property instead of injecting the default value into $form_state['input']. By doing that, you're overwriting whatever $_POST data the user has submitted.

Example:

<?php
function MYMODULE_form_views_exposed_form_alter(&$form, &$form_state) {
  if ($form_state['view']->name == 'your_view_name') {
    if (isset($_GET['option1'])) {
      $form['filter_field']['#default_value'] = $_GET['option1'];
    }
  }
}
?>

Answer 5

Did you try some jquery to act on the href attribute of the button to rewrite the link that gives access to the page views, something like :

$(".my-button-class").each(function() {
$(this).attr("href", "/view-path?option=1");
});
