Hello!!
I have a problem: I need to add a filter associated to a Custom Field.

I installed the plugin “Advanced Custom Fields” and I created a field type “Date Picker” with key “Fecha_de_Estreno“, until here everything ok.

Now I want to add in my theme a new filter associated with this new field and do not know how I can do.

My theme currently has several filters
Sort By:
Date
Title
Site Rating
User Rating
Fecha de Estreno (this is what I added but does not work)

I have a template called “dropdown-filter.php” with this code:

<?php
global $gp_settings;

// Dropdown Filter URLs
$page_url = $_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"];
$short_page_url = $_SERVER["REQUEST_URI"];
$cat_id = get_query_var('cat');
$category_url = get_category_link($cat_id);

if( is_search() ) {

  $category_url = $category_url.'?s='.esc_html($s).'&'; 

} else {

  $term = get_term_by('slug', get_query_var('term'), get_query_var('taxonomy'));
  $tax_name = get_taxonomy(get_query_var('taxonomy'));

  if( $tax_name && ! $tax_name->hierarchical ) {

    if( $tax_name->name == 'release_date' ) {
      $cat_slug = $theme_review_tag_1_slug;
    } elseif( $tax_name->name == 'genre' ) {
      $cat_slug = $theme_review_tag_2_slug;         
    } elseif( $tax_name->name == 'rating' ) {
      $cat_slug = $theme_review_tag_3_slug;
    } elseif( $tax_name->name == 'director' ) {
      $cat_slug = $theme_review_tag_4_slug;
    } elseif( $tax_name->name == 'producer' ) {
      $cat_slug = $theme_review_tag_5_slug;
    } elseif( $tax_name->name == 'screenwriter' ) {
      $cat_slug = $theme_review_tag_6_slug;
    } elseif( $tax_name->name == 'studio' ) {
      $cat_slug = $theme_review_tag_7_slug;
    } elseif( $tax_name->name == 'starring' ) {
      $cat_slug = $theme_review_tag_8_slug;
    } else {
      $cat_slug = $tax_name->name;
    }

  } else {
    if( get_option("permalink_structure") ) {
      $cat_slug = $theme_review_cat_slug;
    } else {
      $cat_slug = "review_categories";
    }
  }

 if( get_option("permalink_structure") ) {
    $category_url = home_url() . '/'. $cat_slug . '/' . $term->slug . '/?';
  } else { 
    $category_url = home_url() . '?' . $cat_slug . '=' . $term->slug . '&'; 
  }

}

?>

<div id="dropdown-filter">
  <div class="order-by-text"><?php _e('Sory By', 'gp_lang'); ?>:</div>
  <form class="order-by-form">
    <select>
<option value="<?php echo $category_url; ?>orderby=meta_value&meta_key=fecha_de_estreno"<?php if(preg_match('/orderby=meta_value&meta_key=fecha_de_estreno/', $page_url)) { ?> selected<?php } ?>><?php _e('Fecha de Estreno', 'gp_lang'); ?></option>

    </select>
  </form>
  <div class="order-text"><?php _e('Order', 'gp_lang'); ?>:</div>
  <form class="order-form">
    <select>
      <option value="<?php if(preg_match('/orderby=/', $page_url) OR preg_match('/gdsr_sort=/', $page_url) OR !get_option("permalink_structure")) { ?><?php echo $short_page_url; ?>&order=desc&gdsr_order=desc<?php } else { ?><?php echo $short_page_url; ?>?order=desc<?php } ?>"<?php if(preg_match('/order=desc/', $page_url)) { ?> selected<?php } ?>><?php _e('Descending', 'gp_lang'); ?></option>                          
      <option value="<?php if(preg_match('/orderby=/', $page_url) OR preg_match('/gdsr_sort=/', $page_url) OR !get_option("permalink_structure")) { ?><?php echo $short_page_url; ?>&order=asc&gdsr_order=asc<?php } else { ?><?php echo $short_page_url; ?>?order=asc<?php } ?>" <?php if(preg_match('/order=asc/', $page_url)) { ?> selected<?php } ?>><?php _e('Ascending', 'gp_lang'); ?></option>              
    </select>
  </form>
</div>

I have added this

<option value="<?php echo $category_url; ?>orderby=meta_value&meta_key=fecha_de_estreno"<?php if(preg_match('/orderby=meta_value&meta_key=fecha_de_estreno/', $page_url)) { ?> selected<?php } ?>><?php _e('Fecha de Estreno', 'gp_lang'); ?></option>

below this

<div id="dropdown-filter">
  <div class="order-by-text"><?php _e('Sory By', 'gp_lang'); ?>:</div>
  <form class="order-by-form">
    <select>

but it does not work

The plugin (Advanced Custom Fields) support tells me I have to add something like this

http://www.advancedcustomfields.com/resources/field-types/date-picker/

but not that I have to do.

I have added different dates in the Date Piker of each post but not sorted correctly in the filter.
When I click on Fecha de Estreno (Custom Field) is ordered in the same way you sort by “Date” and this would have to order by the day of the Date Piker for each post

I do not know if I have to add something more

Eg: http://lafilmoteca.net/categoria/peliculas/

please help is very important for me

thank you very much

Hi @realroy

Thanks for all the code, but I have no idea what you are expecting it to do. You say:
but it does not work

Can you elaborate on this so I can provide clear advise?

Thanks
E
