Je voudrais créer unformulaire de recherche avancéepour untype depublicationpersonnalisé spécifique,avec desfiltrespour lestypes depublicationpersonnalisés,les champspersonnalisés,lestaxonomiespersonnaliséeset pour lespropriétés destypes depublicationpersonnalisées distinctes (champset taxonomies) qui seront des liens aupremiertype depublication à l'aide d'un champ de relationpersonnalisé.

J'ai récemment commencé avec lestypes depublications,les champset lestaxonomiespersonnalisés de WP,je l'aimejusqu'àprésent,maispouren tirer lemeilleurparti,j'aimeraispouvoir le rechercher correctement. Dois-je lefairemanuellement? Si oui,comment?

PS. Si cela compte,j'utilise lesplugins: Champspersonnalisés avancés et Interface utilisateur dutype demessagepersonnalisé .

Ci-dessous,j'aifait unemaquette d'unexemple de l'apparence dufiltrageet de son lien avec lestypes depublications ci-dessus.

I'd like to build an advanced search form for a specific custom post type, having filters for the custom post types custom fields, custom taxonomies, and for a separate custom post types properties (fields and taxonomies) which will be links to the first post type using a custom relationship field.

I've recently started off with WPs custom post types, fields, and taxonomies, I love it so far but to make the best of it I'd like to be able to search it properly. Do I need to do it manually? If so, how?

PS. If it matters, I'm using the plugins: Advanced Custom Fields and Custom Post Type UI.

Below I've mocked up an example of how the filtering would look and how it might relate to the post types above.

Jepense que vousferiezmieux d'écrire vous-même quelque chose comme ça.

Jetez un œil à: http://www.catalysthomes.co.uk/homes-for-sale/

Lespropriétés sont chargées dans un CPTet j'aimapropre recherchepersonnalisée dans labarre latérale. De cette recherche,il recherche un certainnombre de chosestelles que lestaxonomies,les champspersonnaliséset le classementparprix de date,etc.

Alors,commentpuis-je yparvenir? Je soumets leformulaire à unmodèle depageet àpartir de là,je traite les données depublicationet crée unenouvelle WP_queryen fonction des critères de recherche. J'utilise des sessionspour stocker les variables de recherche afin depouvoirpaginer les résultats.

WP_Queryesttrèspuissant. Jetez un œil: http://codex.wordpress.org/Class_Reference/WP_Query

Ici,vouspouvez utiliser meta_querypourinterrogerplusieurs champspersonnaliséset utiliser tax_querypourinterroger vostaxonomies,et il y aplus. Voici comment lemien est conçupour vous donner uneidée.

Fichiermodèle:

   <?php
  $temp = $wp_query;
  $wp_query = NULL;
  $args = array();
  ?>

  <?php include("functions/Homes-for-sale/propertyrawresults.php"); ?>
  <?php include("functions/Homes-for-sale/propertysearchresults.php"); ?>

  <?php
  $args['post_type'] = "homes-for-sale";
  $args['showposts'] = 10;
  $args['paged'] = $paged;
  $wp_query = new WP_Query($args);
  ?>

  <?php include("functions/Homes-for-sale/propertylistlayout.php"); ?>

Résultatsbruts

 <?php
if($_POST['sortby']) {
    $_SESSION['prop_selectedsortby'] = $_POST['sortby'];
}

switch($_SESSION['prop_selectedsortby']) {
    case "name-asc": $args['order'] = "ASC"; $args['orderby'] = "title"; break;
    case "name-desc": $args['orderby'] = "title"; break;
    case "price-asc": $args['order'] = "ASC"; $args['orderby'] = "meta_value_num"; $args['meta_key'] = "chb_homes_for_sale_specifics_fmv"; break;
    case "price-desc": $args['orderby'] = "meta_value_num"; $args['meta_key'] = "chb_homes_for_sale_specifics_fmv"; break;
    case "date-asc": $args['order'] = "ASC"; break;
    default: /* No need to set arguments here as wp query defaults */ break;
}

$selectedsortby[$_SESSION['prop_selectedsortby']] = " selected=\"selected\"";
?>

I think something like this you would be best writing yourself.

Take a look at: http://www.catalysthomes.co.uk/homes-for-sale/

Properties are loaded into a CPT and I have my own custom search in the sidebar. Of that search its searching a number of things such as taxonomies, custom fields and ordering by date price etc.

So how do I achieve this? I submit the form to a page template and from there I deal with the post data and build a new WP_query based on the search criteria. I use sessions to store the search variables so that I can paginate the results.

WP_Query is very powerful. Take a look: http://codex.wordpress.org/Class_Reference/WP_Query

In there you can use meta_query to query multiple custom fields and use tax_query to query your taxonomies, plus there is more. Below is how mine is built to give you an idea.

Template File:

  <?php
  $temp = $wp_query;
  $wp_query = NULL;
  $args = array();
  ?>

  <?php include("functions/Homes-for-sale/propertyrawresults.php"); ?>
  <?php include("functions/Homes-for-sale/propertysearchresults.php"); ?>

  <?php
  $args['post_type'] = "homes-for-sale";
  $args['showposts'] = 10;
  $args['paged'] = $paged;
  $wp_query = new WP_Query($args);
  ?>

  <?php include("functions/Homes-for-sale/propertylistlayout.php"); ?>

Raw Results

<?php
if($_POST['sortby']) {
    $_SESSION['prop_selectedsortby'] = $_POST['sortby'];
}

switch($_SESSION['prop_selectedsortby']) {
    case "name-asc": $args['order'] = "ASC"; $args['orderby'] = "title"; break;
    case "name-desc": $args['orderby'] = "title"; break;
    case "price-asc": $args['order'] = "ASC"; $args['orderby'] = "meta_value_num"; $args['meta_key'] = "chb_homes_for_sale_specifics_fmv"; break;
    case "price-desc": $args['orderby'] = "meta_value_num"; $args['meta_key'] = "chb_homes_for_sale_specifics_fmv"; break;
    case "date-asc": $args['order'] = "ASC"; break;
    default: /* No need to set arguments here as wp query defaults */ break;
}

$selectedsortby[$_SESSION['prop_selectedsortby']] = " selected=\"selected\"";
?>

Essayez leplugin Taxonomy Picker ensemble avec Relevanssi.Combinaison detueur.

http://www.squidoo.com/taxonomy-picker-wordpress-plugin http://wordpress.org/extend/plugins/relevanssi/

celane prendpasen compte les relations deposte,qui sont lapartie difficile demonproblème.Ilestbeaucoupplusfacile defiltrer les articlespartaxonomie,je dois lesfiltrerpour acheter lataxonomie (ou champpersonnalisé) d'un article associé.

this doesn't take into account post relationships, that being the difficult part of my problem. It's way easier to filter posts by taxonomy, I need to filter them buy the taxonomy (or custom field) of a related post.

Jetez un œil auplugin Relevanssi,ilpourraitfaire ce que vous recherchez: http://wordpress.org/extend/plugins/relevanssi/

Celane convientpas à l'approche dontj'aibesoin (avec desfiltres spécifiques),mais c'est unplugintrèsintéressant,cela ressemble à unexcellent remplacementpour lafonction de recherchepar défaut,mercibeaucoup de l'avoir signalé.

It doesn't suit the approach that I need (with specific filters), but it's a very interesting plugin, it looks like a great replacement for the default search function, thanks very much for pointing it out.

Si quelqu'un a des difficultés àmettreen œuvre la solution de Brady ci-dessus (commeje l'aifait),voici unindice:il semble que WordPress a desproblèmes avec latransmission des données de session,vous devrez doncprobablementfaire quelque chose depluspour lefairefonctionner correctement.Lesproblèmes sont discutésici

Dansfunctions.php:

 function init_sessions() {
  if (!session_id()) {
  session_start();
 }
}
add_action('init', 'init_sessions');

Dans votremodèle:

 /**
* Enable sessions
*/
if (!session_id())
session_start();

Pourmoi,l'installation duplugin " Simple Session Support " de Peter Wooster apermistour.

If anyone is having difficulty implementing Brady's solution above (as I did) here's a hint: It appears that WordPress has some problems with passing session data so you will probably have to do something extra to make it work properly. The issues are discussed here

In functions.php:

function init_sessions() {
  if (!session_id()) {
  session_start();
 }
}
add_action('init', 'init_sessions');

In your template:

/**
* Enable sessions
*/
if (!session_id())
session_start();

For me installing Peter Wooster's "Simple Session Support" plugin did the trick.

Hi Steve. Thanks for posting your first answer here. Glad to have you at WPSE. For future reference, answers shouldn't pivot completely on an external link. If the link is disabled, your answer becomes benign. Would you mind updating your answer with a couple of sample relevant code snippets?
