Hey all, looking to have a nested loop feed data into a json-able php array, encode that array, then be able to call it via AJAX. I have the AJAX part down, but making the array properly is giving me some trouble.
Code for what the JSON should look like (rough outline):
[{
"topic-title" : [
{
"title" : "the_title",
"link" : "get_permalink"
},{
"title" : "the_title",
"link" : "get_permalink"
}
// etc.
] ,
"next-topic-title : [
{
"title" : "the_title",
"link" : get_permalink"
}, {
"title" : "the_title",
"link" : "get_permalink"
}
// etc.
]
// etc.
}]It should be echoed from this code, but I'm getting 'undefined' when I console.log it in the browser.
function reload_topics() {
$final = array();
$tax_sh = get_terms(
array(
'section'
),array(
'orderby' => 'name',
'order' => 'ASC',
'hide_empty' => true,
'hierarchical' => true
)
);
foreach ($tax_sh as $term) {
$argsh = array(
'post-type' => 'custom-post-type',
'tax_query' => array(
array(
'taxonomy' => 'section',
'field' => 'slug',
'terms' => $term->slug
)
)
);
$content = array();
$this_term = $term->slug;
$content[$this_term] = array();
$inner_query = new WP_Query($argsh);
if( $inner_query -> have_posts() ) : while( $inner_query -> have_posts() ) : $inner_query->the_post();
$this_post = array("title" => get_the_title(), "link" => get_permalink($post->ID));
array_push($content[$the_term],$this_post);
endwhile;
else:
endif;
array_push($final,$content);
}
$final_encode = json_encode($final);
echo $final_encode;
die();
}If there is a much easier way to do this or a tutorial I can work through that would be much appreciated, but I haven't been able to enter the correct terms into Google to find a good tutorial, except the upvote downvote tutorial that is on a few sites; it does not cover this exactly, but definitely helped with the AJAX part.
Thanks!
