Tags autocomplete in frontend post form?

There’s lots of ways it can be accomplished 🙂

Thank you a lot for your answer, I will go through the documentation!

Cheers!

Your tag functionality for custom tags does not work. I get it working with a drop down, but it means you can not create new tags. and even with the drop down it does not work it some how allocates an id as the custom tag and creates a tag like that

ninja forms is having a solution where it seems to be working

For my use, I finally didn’t need to have the autocomplete functionnality on the tag field (and it worked only for 1 tag after a quick test), but work very fine with a text field :

<script>
    jQuery(document).ready(function($) {
        var availableTags = [
	<?php
	    $recentPosts = new WP_Query();
	    $recentPosts->query(&#039;showposts=100&#039;);
	    while ($recentPosts->have_posts()) : $recentPosts->the_post(); ?>
	    "<?php echo get_post_meta( $post->ID, &#039;marque&#039;, true ); ?>",
	    <?php endwhile; ?>
	];

	$( "#marque" ).autocomplete({
	    source: availableTags
	});
});
	</script>

and how do you save it into tag form afterwards ?

The id #marque is “connected” to the id of your field, afer you only have tu do a query to retrieve the tags and format them according to the syntax example of the autocomplete jQuery plugin,

What I actually mean is how do you save it as a proper taxonomy afterward in wordpress. so it is availabe as a non hierarchical taxonomy
