Hi everyone!
I really like the plugin, it is great.
I have been pairing it with a custom post type displaying concert dates, I can get all my posts to work fine and I can use WP_Query and $args to filter/order them simply. I use a datepicker ACF field ‘date_selector’, and “orderby” to order them by date.
Things got more complicated then…
I am trying to create a basic select menu with 2 options that would help sorting/reordering the posts based on their date. Just changing the “orderby” value for now would be enough to understand the way it works.
From the ACF documentation, I understand that you can use if( isset($_GET['your-option']) ) to get the URL parameter and then use that to make some changes in your arrays?
Sorry if I am lost. Here is my code for the cpt:
<?php
$today = date('Y-m-d H:i:s');
$args = array(
'post_type' => 'agenda',
'posts_per_page' => 8,
'meta_key' => 'date_selector',
'orderby' => 'meta_value',
'order' => 'DESC',
'suppress_filters' => true,
'lang' => '',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'date_selector',
'value' => $today,
'type' => 'DATE',
'compare' => '<',
)
)
)
?>
<div class="filtering-box fl-2 on_w g_sm_mt">
<p>Sort by:</p>
<form action="<?php the_permalink(); ?>" method="get">
<select name="filter" id="date-filter">
<option value="date-recent">Now</option>
<option value="to-come">To come</option>
</select>
<button type="submit" value="">Sort</button>
</form>
</div>
<wrapper class="events-container g_sm_mt">
<?php
function my_pre_get_posts( $query ) {
// do not modify queries in the admin
if( is_admin() ) {
return $query;
}
// only modify queries for 'event' post type
if( isset($query->query_vars['post_type']) && $query->query_vars['post_type'] == 'agenda' ) {
// allow the url to alter the query
if( isset($_GET['date-recent']) ) {
$args = array(
'post_type' => 'agenda',
'posts_per_page' => 1,
'meta_query' => array(
'key' => 'date_selector',
'value' => $today,
'type' => 'DATE',
'compare' => '>',
)
);
}
// return
return $query;
}
}
add_action('pre_get_posts', 'my_pre_get_posts');
?>
<?php //Query posts
$agenda_dates = new WP_Query( $args ); ?>
<?php if ($agenda_dates->have_posts()): ?>
<?php while ($agenda_dates->have_posts()): $agenda_dates->the_post();?>
//my posts here...
<?php endwhile;?>
<?php endif;?>
<?php wp_reset_postdata();?>
I got this far, it keeps working but the filter option does not change anything to the posts when I select the value “date-recent”. Sorry for this poor attempt, I am not good at php and do not understand how to implement the sorting option.
I am not even sure about the syntax and where I should write the URL parameter condition if( isset($_GET['...'])).
Can anyone of you help me with this?
Thank you,
Have a nice day!
