Custom Taxonomy Filtering with Wordpress - wordpress

Question

Ive been trying to figure this out for three days now, even using solutions on this site. I still cant get this working.
I have a wordpress loop that uses a filter to show posts by post type. Now the post type is called "case-studies" Thus all the posts in the type case studies are shown.
But i need to hide a specific taxonomy term from this loop. The taxonomy is called "sectors" and the term is "healthcare". Ive tried all manner of combinations but still cant get this. I need this pretty urgent. Anyone who can help would save my life.
Here is the query and the loop
<?php
// The Query
$the_query = new WP_Query( 'post_type=case-studies&posts_per_page=-1' );
// The Loop
while ( $the_query->have_posts() ) :
$the_query->the_post();
?>

Answer 1

$args = array(
'post_type' => 'case-studies',
'tax_query' => array(
array(
'taxonomy' => 'sectors',
'field' => 'slug',
'terms' => array('comercial', 'personal', 'etc') //excluding the term you dont want.
)
)
);
$query = new WP_Query( $args );
I dind´t try it but you could just make a query calling only the terms you want, you could previously populate the terms array listing all the terms on the taxonomy and excluding the one you want, i think this is a little hacky it should be another straight forward way to do it but give it a try since it is a case of life or dead =).

Answer 2

Try this one:
<?php
$type = 'cpreviews';
$args=array(
'post_type' => $type,
'post_status' => 'publish',
'posts_per_page' => -1,
'caller_get_posts'=> 1
);
$my_query = null;
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>
<p><?php the_title(); ?></p>
<?php
endwhile;
}
wp_reset_query(); // Restore global post data stomped by the_post().
?>

ok then try this one it will extract your terms dinamicaly and exclude the term you dont want, i didn´t check if it is working but this is the logic, please check for sintax errors.
$terms = get_terms("sectors");
$count = count($terms);
$termsAr = array();
if ($count > 0 ){
foreach ( $terms as $term ) {
if($term->name !== "healthcare"){//Here we exclude the term or terms we dont want to show
array_push($termsAr, $term->name);
}
}
}
$terms = get_terms("types");
$count = count($terms);
$termsAr2 = array();
if ($count > 0 ){
foreach ( $terms as $term ) {
if($term->name !== "healthcare"){//Here we exclude the term or terms we dont want to show
array_push($termsAr2, $term->name);
}
}
}
$args = array(
'post_type' => 'case-studies',
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => 'sectors',
'field' => 'slug',
'terms' => $termsAr //excluding the term you dont want.
),
array(
'taxonomy' => 'types',
'field' => 'slug',
'terms' => $termsAr2 //excluding the term you dont want.
)
)
);
$query = new WP_Query( $args );
