showing no posts on wp_query

Question

I am setting up a custom post type for wordpress and now i'm trying to display the posts on the homepage. I would like to hide the posts until they are called via has_tag i'm using the following code but it displays all of the posts.

$args = array( 'post_type' => 'homepage', 'posts_per_page' => -1 );
$loop = new WP_Query( $args ); 

while ( $loop->have_posts() ) : 
    $loop->the_post();
    echo '<div class="entry-content">';
    the_content();
    echo '</div>';
endwhile;

Answer 1

So I was able to get this accomplished by using the following code.

<?php

$args = array(
'post_type' => 'homepage',
);
$the_query = new WP_Query( $args ); ?>

<?php
// The Loop
if ( $the_query->have_posts() ) {
echo '<ul>';
while ( $the_query->have_posts() ) {
$the_query->the_post();
if (has_tag('footer')) {
echo '<li>' . get_the_title() . '</li>';
}
}
echo '</ul>';
} rewind_posts();




// The Loop
if ( $the_query->have_posts() ) {

while ( $the_query->have_posts() ) {
$the_query->the_post();
if (has_tag('cta')) {
echo '<div class="cta-style">' . get_the_title() . '</div>';
}
}

}  ?>
