What should increasing the priority to 20 change?
From the “class-acf-field-select.php” i see that there isn’t an possibility to “disable” options.
The select itself use the “disable” in line 318.
if( !empty($field['disabled']) ) $select['disabled'] = 'disabled';
the select itself is rendered via
acf_select_input( $select );
which is in acf-input-functions.php
acf_get_select_input calls acf_walk_select_input($choices, $value)
where the “option tags are rended with “value”, “selected” and “data-i” attributes.
So no “disabled” html attribute.
// single (option)
} else {
$attrs = array(
'value' => $value
);
// If is selected.
$pos = array_search( esc_attr($value), $values );
if( $pos !== false ) {
$attrs['selected'] = 'selected';
$attrs['data-i'] = $pos;
}
$html .= sprintf( '<option %s>%s</option>', acf_esc_attr($attrs), esc_html($label) );
}
If there would be a way to access the form “post_id” to filter function of the field i could delete the “not wanted options” from the array when post_id is e.g. “new_post”.
