I would like to have the option to output the textarea as a list, like the automatically add breaks and autop.
I have modified the class file class-acf-field-textarea.php
by adding this at the to the choices array;
'li' => __("Add li tags"),
and modifying the function format_value() like this;
function format_value( $value, $post_id, $field ) {
// bail early if no value or not for template
if( empty($value) || !is_string($value) ) {
return $value;
}
// new lines
if( $field['new_lines'] == 'wpautop' ) {
$value = wpautop($value);
} elseif( $field['new_lines'] == 'br' ) {
$value = nl2br($value);
} elseif ($field['new_lines'] == 'li') {
$value = '<ul><li>'.$value;
$value = str_replace(array("\r\n", "\r", "\n"), "</li><li>", $value);
$value .= '</li></ul>';
$value = str_replace("<li></li>", "", $value);
}
// return
return $value;
}
which works nicely but, of course, it will get overwritten by the next update and should be in a filter.
How is the proper way to do this?
According to the docs, the first part should be;
function my_acf_load_field( $field ) {
$field['choices'] = array(
'li' => 'Add li tags'
);
return $field;
}
add_filter('acf/load_field/type=textarea', 'my_acf_load_field');
but this doesn’t work.
and the second part I have to override the function in acf/load_values but I don’t know how this filter would work.
Thanks for any help.
