* What’s wrong with my last function ?
What should I write inside the value attribute?
* Also I wrote what you said in my footer.php but it didn’t worked. I think the
main problem is in my last function in functions.php which I referred to above.
* Thank You.

* Thanks Will.
The problem is I don’t want to prevent generating different sizes
for ALL images. I want WP generate all sizes JUST for the first image in my posts(
because it’s feature image & all generated sizes will be use on index), but NOT
for other images.
* Any idea ?

* Hello.
I have problems with custom fields and I appreciate if someone can help
me on this. I created a Download Box using custom fields & styled it. the code
is this :
* ```
ID, 'download', true );
if( isset($cf_var) && !empty(cf_var) ) : ?>
-
Download HQ
ID, 'download2', true );
if( isset($cf_var) && !empty(cf_var) ) : ?>
-
Download HQ
ID, 'password', true );
if( isset($cf_var) && !empty(cf_var) ) : ?>
-
Password:
```
* So I styled them in styles.css .
The problem is whether the post has custom
field assigned, or not, the Download Box is showing.
* After reading this topic, I end up with this in my functions.php :
* ```
/**
* Download box using Custom Fields
*/
function display_download_box() {
if( !is_singular() ) {
return;
}
$custom_fields_array() = array(
'download' => 'download',
'download2' => 'download2',
'password' => 'password',
);
$output = custom_fields_iteration( $custom_fields_array );
if( strlen($output) > 0 ) {
echo '
' . $output . '
';
}
}
function custom_fields_iteration( $custom_fields_array ) {
$output = '';
foreach( $custom_fields_array as $custom_field => $data ) :
$custom_field_value = get_post_meta( get_the_ID(), $custom_field, true );
$output .= ( strlen($custom_field_value) > 0 ? 'div class="download">
' . $data . ': ' . $custom_field_value . '
