I need someone to help me out on this please!!!

I want to chain the select LOCATION to that of COUNTRY

I mean if someone chose under country i.e Nigeria then under location ALL Nigeria states will be available to select.

These are the codes:

<label for=”country”>Country</label>

<select id=”country” class=”show-menu-arrow selectpicker” name=”coun”>

<option value=””>-</option>
<option value=”nigeria”>Nigeria</otpion>
<option value=”germany”>Germany</option>
<?php

$args=array(

‘post_type’ => ‘Property’,

‘posts_per_page’ => -1,

);

$i = 0;

$locations = array();

$wp_query=new WP_Query($args);

while($wp_query->have_posts()):$wp_query->the_post();

?>

<?php

$value = get_post_meta(get_the_ID(),’_cmb_pro_country’, true);

if (!in_array($value, $locations) && $value != ”) {

$locations[$i] = $value;

?>

<option value=”<?php echo get_post_meta(get_the_ID(),’_cmb_pro_country’, true);?>”><?php echo get_post_meta(get_the_ID(),’_cmb_pro_country’, true);?></option>

<?php } ?>

<?php $i++; ?>

<?php endwhile;?>

</select>

<label for=”location”>Location</label>

<select id=”location” class=”show-menu-arrow selectpicker” name=”location”>

<option value=””>-</option>
<option value=”lagos”>Lagos</option>
<option value=”abuja”>Abuja</option>
<?php

$args=array(

‘post_type’ => ‘Property’,

‘posts_per_page’ => -1,

);

$i = 0;

$locations = array();

$wp_query=new WP_Query($args);

while($wp_query->have_posts()):$wp_query->the_post();

$value = get_post_meta(get_the_ID(),’_cmb_pro_location’, true);

if (!in_array($value, $locations) && $value != ”) {

$locations[$i] = $value;

?>

<option value=”<?php echo get_post_meta(get_the_ID(),’_cmb_pro_location’, true);?>”><?php echo get_post_meta(get_the_ID(),’_cmb_pro_location’, true);?></option>

<?php }

$i++;

endwhile;?>

</select>

I need help seriously.

Please can someone help me out also?

After I attempt to upgrade I received this error:
Fatal error: Cannot redeclare get_avatar_url() (previously declared in /home/propert7/public_html/wp-includes/link-template.php:3414) in /home/propert7/public_html/wp-content/themes/wpestate/libs/shortcodes.php on line 741

Since then, I was unable to log-in with /wp-login again even my website doesn’t display any information apart from the above error message.

I need help urgently!
