Help with coding

I am wanting to have all CPTs and their assoc. categories visible to chose from on the Add Listings page, except the Events. I would like to have Events and their assoc. categories on the Add Event page, without the other CPTs.

I used this in my child functions file:

function geodir_add_listing_before_detail_fields(){

global $post;

$current_posttype = geodir_get_current_posttype();

$geodir_allow_posttype = get_option(‘geodir_allow_posttype_frontend’);

$post_types = geodir_get_posttypes(‘object’);

$addlisting_links = ”;
foreach($post_types as $key => $postobj){

if(is_array($geodir_allow_posttype) && in_array($key, $geodir_allow_posttype) && count($geodir_allow_posttype) > 1){

$name = $postobj->labels->singular_name;

$checked = ”;
if($current_posttype == $key)
$checked = ‘checked=”checked”‘;

$add_link = geodir_get_addlisting_link( $key );

$addlisting_links .= ‘<div style=”display:block;line-height:30px; margin-right:5px; float:left;”>’;
$addlisting_links .= ‘<input type=”radio” ‘.$checked.’ value=”‘.$add_link.'” title=”‘.ucfirst($name).'” name=”geodir_select_add_listing[]” onchange=”javascript:window.location=this.value;” >’.ucfirst($name);
$addlisting_links .= ‘</div>’;

}

}

if($addlisting_links != ”){ ?>

<h5><?php _e(‘Select Listing Type’, GEODIRECTORY_TEXTDOMAIN);?></h5>

<div class=”geodir_form_row clearfix”>
<div id=”geodir_showposttypes” class=”geodir_showposttypes”>
<?php echo $addlisting_links;?>
</div>
</div> <?php

}

}

As was found here: https://wpgeodirectory.com/support/topic/one-link-only-for-custom-post-types/#post-8362

And it does work, as it should, except it shows all CPTs in both the “Add Listing” page and the “Add Event” page. But I need it refined for my purposes and am not good enough at coding to do it correctly.

Is there anyone who would like this job? Thanks!
