Hello, I am trying to get posts based on ACFs by choosing from a select box.

The form is like this`<?php ?>
<form method=”post” action=”<?php echo $_SERVER['PHP_SELF']; ?>”>
<select name=”my_city” id=”city” class=”postform” onchange=”submit();”>
<option selected=”selected”>Choose a size</option>
<option value=”la”>Los Angeles</option>
<option value=”london”>London</option>
</select>
</form>`

And Query is like this

<?php 
 
	// args
	$city = isset($_GET['my_city']) ;

	$args = array(
		'numberposts' => -1,
		'post_type' => 'jobs',
		'meta_key' => 'city_country',
		'meta_value' => $city
	);
	 
	// get results
	$the_query = new WP_Query( $args );
	 
	// The Loop
	?>
	<?php if( $the_query->have_posts() ): ?>
		<ul>
		<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
			<li>
				<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
			</li>
		<?php endwhile; ?>
		</ul>
	<?php endif; ?>
	 
	<?php wp_reset_query();  // Restore global post data stomped by the_post(). ?>

Yet I cant list posts on select box change it redirects me to the homepage. I have tried my different ways still no luck. Anyone care to help.

Thanks

Hi @downer

I think your issue is a logic error in your code. The line:

$city = isset($_GET['my_city']) ;

Will set to true / false, not the value. Perhaps you mean to do this.

$city = '';
if( isset($_GET['my_city']) )
{
$city = $_GET['my_city'];
}

Thanks for the response, Elliot.

I have created a separate PHP file to display results and it worked.

I have used this

$city = $_POST['citycountry'];
