I want to add a second dropdown to the filter for gender. What template would I do this in?

@ Adam

How are you setting the gender?

[Adam Leone]

Its a custom field. I just need to know what file I would add the dropdown code to.

@ Adam

You do not really add it to a template file, sort of… so it is somewhat difficult to explain…

I see you’ve purchased cMap sooo… you could add the code to the cmap.php file. I recommend using the Code Snippets plugin to add the drop down. This way adding the drop down is update safe.

You would hook into the cn_action_list_before-cmap action to render the drop down. Example:

add_action( 'cn_action_list_before-cmap', 'cn_add_gender_dropdown', 5 );

function cn_add_gender_dropdown() {
    //echo you code for the drop drown
}

To make it functional you will also need to hook into the cn_list_retrieve_atts-cmap filter like so:

add_filter( 'cn_list_retrieve_atts-cmap', 'cn_gender_meta_query' );

function cn_gender_meta_query( $atts ) {
    // NOTE: only set the meta query if the user has selected a gender
    $atts['meta_query'] = array( 'meta_key'=> '{custom-field-id}', 'meta_value' => '{gender}');
    return $atts;
}

I have since discovered its not a custom field but the ‘Suffix’ field. What would be the code required for that?

[Steven Zahm]

@ Adam

Well, the code for the drop down would be the same, the issue is there is no method available which can be easily implemented to search the suffix field.

[Adam Leone]

I have used the following code to get gender to be searchable:

 if (isset ($_GET['gender']) && $_GET['gender']) {
         $where[] = ' AND honorific_suffix = "' . htmlentities($_GET['gender'], ENT_QUOTES) . '"';
     } 

However there are 2 issues:

1. The gender box resets when the search is performed
2. The text does not say that the user searched the gender as it does for category:

“You are searching within category(ies): Accident and emergency”

How do I get the text to also say “”You are searching within gender: Male” for example?

RE: The gender box resets when the search is performed

In the code you used to create the dropdown (I assume that is what you mean by gender box) you need to check for gender query string and set the option selected tag in the drop down.

RE: The text does not say that the user searched the gender as it does for category:

You can hook into the cn_search_results_messages filter which passes an array of search messages. YOu can add you gender message to the array if the user is searching by one.

Hope this helps!

Hi Steven,

Where can I read about that hook (cn_search_results_messages)

Thanks,

David

@ Adam

There’s nothing available to read. You would hook into like the other filters:

add_filter( 'cn_search_results_messages', 'cn_gender_search_results_messages' );

function cn_gender_search_results_messages( $messages ) {
    $messages['cn-gender'] => 'The results are being filtered by gender.';
    return $messages;
}

You would of course add the logic to deal with changing the message string based on if gender is being search and by which.
