Multiple taxonomy with next_post_link

I really need help…

Did someone have a idea ?

Hi,

before you answer me i found a solution and it’s like in your sample !

The small difference is that i have to check where i come form in order to search only in the taxonomy i just select. My problem was that some product could be in 2 taxonomy or more.

Here is my function code :

function generate_url($produit_type = null, $produit_marque = null, $prix = null, $produits = null, $search = false)
{
	$url_query = "?";
	$noEmpty = false;
	if(isset($produit_type))
	{
		if($noEmpty) $url_query .= '&';
		$url_query .= REWRITE_PRODUIT_TYPE . "=" . $produit_type;
		$noEmpty = true;
	}
	if(isset($produit_marque))
	{
		if($noEmpty) $url_query .= '&';
		$url_query .= REWRITE_PRODUIT_MARQUE . "=" . $produit_marque;
		$noEmpty = true;
	}
	if(isset($prix))
	{
		if($noEmpty) $url_query .= '&';
		$url_query .= REWRITE_PRODUIT_PRIX . "=" . $prix;
		$noEmpty = true;
	}
	if($search)
	{
		if($noEmpty) $url_query .= '&';
		$url_query .= REWRITE_SEARCH . "=1";
	}
	return $url_query;
}

function decompose_url() {
	$data = array();
	// Dans tous les cas je récupère les produits dans les cookies
	if(isset($_COOKIE[REWRITE_PRODUITS]) && !empty($_COOKIE[REWRITE_PRODUITS])) {
		$data[REWRITE_PRODUITS] = str_replace('\\','', $_COOKIE[REWRITE_PRODUITS]);
	}

	if(isset($_GET[REWRITE_PRODUIT_TYPE]) && !empty($_GET[REWRITE_PRODUIT_TYPE]))
		$data[REWRITE_PRODUIT_TYPE] = array(
			'taxonomy'	=> 'produit_type',
			'field'		=> 'slug',
			'terms'		=> $_GET[REWRITE_PRODUIT_TYPE]
		);

	if(isset($_GET[REWRITE_PRODUIT_MARQUE]) && !empty($_GET[REWRITE_PRODUIT_MARQUE]))
		$data[REWRITE_PRODUIT_MARQUE] = array(
			'taxonomy'	=> 'produit_marque',
			'field'		=> 'slug',
			'terms'		=> $_GET[REWRITE_PRODUIT_MARQUE]
		);

	if(isset($_GET[REWRITE_PRODUIT_PRIX]) && !empty($_GET[REWRITE_PRODUIT_PRIX]))
		$data[REWRITE_PRODUIT_PRIX] = $_GET[REWRITE_PRODUIT_PRIX];

	if(isset($_GET[REWRITE_SEARCH]) && !empty($_GET[REWRITE_SEARCH]) && ($_GET[REWRITE_SEARCH]==1))
		$data[REWRITE_SEARCH] = 1;

// echo "<pre>";
// print_r($data);

	return $data;

Thanks for your help

Hi,

I think your problem is that you have 2 links…

The first is
<a>getPermalink() ?>">...</a>
And the second link is inside the first one ! :
<a>getPermalink() ?>">...<?php the_content('Read more...'); ?>...</a>

I must not have a link include in an other link !

For your information i do that in my page :

<a class="entry-content produit <?php echo $class;?>" href="<?php the_permalink(); ?><?php if(isset($url)) echo $url;?>">
	<div class="vendu" style="<?php echo $vendu_display;?>"></div>
	<div class="fadehover">
		<?php
		echo wp_get_attachment_image(get_field('my_custom_field1'), 'produit-apercu', $icon, array('class'=>'apercu-noir-et-blanc') );
		echo wp_get_attachment_image(get_field('my_custom_field2'), 'produit-apercu', $icon, array('class'=>'apercu') );
		?>
	</div>
	<ul>
<?php
$data = get_field('my_custom_field3');
if ($data):?>
		<li><h4><?php echo truncateHtml($data,28, '...', true); ?></h4></li>
<?php endif;
$taxonomies = get_the_terms(get_the_ID(),my_id);
$brand = "";
if(!empty($taxonomies) && is_array($taxonomies)) {
	foreach($taxonomies as $t){
		$brand = $t->name;
		break;
	}
}
$price = get_field(my_custom_field4);

if ($brand && price ):?>
			<li class="brand-price"><?php echo $brand;?> - <?php echo price; ?> €<?php echo $loop->current_post;?></li>
<?php endif; ?>
	</ul>
</a>

Using this function :

/**

 *
