Custom Fields Search

    Is it possible to write a search that asks for various different Meta_Keys?

    I have posts with multiple custom field entries.

    Lets say a user wants to search for posts where I was reading a specific book (entered in the custom field) and only display the ones where I was happy when posting (another custom field).

    More Background:

    I figured out how to modify the search form. I entered all the inputs just to test. Then when you set the form action to home and request the variables you just set, you can call them (did a few echos to test. said “you serached for $var1 $var2, etc)

    Got it hooked up, but it doesn’t work when I go trying to define the same thing over and over.

    Any suggestions on an approach here? 

    <?PHP 

  $candy = $_REQUEST['candy'] ;
  $mood = $_REQUEST['mood'] ;
  $booktype = $_REQUEST['booktype'] ;
  $bookpgs = $_REQUEST['bookpgs'] ; 

 ?> 

 <?php

 $querystr = "
    SELECT wposts.*
    FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta
    WHERE wposts.ID = wpostmeta.post_id
	AND wpostmeta.meta_key = 'candy'
	AND wpostmeta.meta_value = '$candy'
	AND wpostmeta.meta_key = 'mood'
	AND wpostmeta.meta_value = '$mood'
	AND wpostmeta.meta_key = 'booktype'
	AND wpostmeta.meta_value = '$booktype'
	AND wpostmeta.meta_key = 'bookpgs'
	AND wpostmeta.meta_value = '$bookpgs'
    AND wposts.post_status = 'publish'
    AND wposts.post_type = 'post'
    ORDER BY wposts.post_date DESC
 ";

 $pageposts = $wpdb->get_results($querystr, OBJECT); ?>

    Thanks 🙂

    Thanks for the link, but this does not really solve the issue of having a search engine that uses certain meta field values to narrow down the search following user-selected combo boxes and check boxes. Or at least I am unable to see how it could.

    The code I provided can be used as a starting point to provide the functionality you are looking for. The goal of the search updates I made were look for matches that found in a meta field or the post content.

    In order to use the meta fields to narrow down the search, you would need to update the plugin code I provided to include an additional AND clause before the full query is assembled and returned:

    $term = $wpdb->escape($var_q);
if (!$_GET['sentense'] && Count($search_terms) > 1 && $search_terms[0] != $var_q) {
    $query .= " OR ($wpdb->posts.post_title LIKE '{$n}{$term}{$n}')";
    $query .= " OR ($wpdb->posts.post_content LIKE '{$n}{$term}{$n}')";
}

//begin new code
if ($_GET['limit_author']) {
    $limit_author = $_GET['limit_author'];
    $query .= " AND (";
    $query .= "($wpdb->postmeta.meta_key = 'author')";
    $query .= " AND ($wpdb->postmeta.meta_value  LIKE '{$n}{$limit_author}{$n}')";
    $query .= ") ";
}
//end new code

if (!empty($query)) {
    $where = " AND ({$query}) AND ($wpdb->posts.post_status = 'publish') ";
}

    I’ve not tested it, but it should give you an idea of how and where to update the query.
