I’m having a similar issue with the acf/load_field hook, though it seems like the data for the select is working properly the select2 script isn’t initializing. I have a Select field within a Flexible Content / Repeater that loads icons from a CSS file:
add_filter( 'acf/load_field/key=field_58a4b7d2dc743', function( $field ){
$stargate = file_get_contents( get_template_directory() . '/assets/styles/icons/stargate.css' );
preg_match_all( '/\.(.*):before/', $stargate, $choices );
$choices = $choices[1];
$field['choices'] = array(
'' => ''
);
if( $choices ){
sort( $choices );
foreach( $choices as $choice ){
$field['choices'][$choice] = $choice;
}
}
return $field;
} );
which seems to be working, because my select markup contains the correct options:
<select id="acf-field_57ab771f7670b-6-field_57ae32e9ae604-58e285a16d10a-field_58a4b7d2dc743" class="" name="acf[field_57ab771f7670b][6][field_57ae32e9ae604][58e285a16d10a][field_58a4b7d2dc743]" data-ui="0" data-ajax="0" data-multiple="0" data-placeholder="Select" data-allow_null="0" tabindex="-1" title="Icon" style="display: none;">
<option value="" selected="selected" data-i="0" class=""></option>
<option value="zsg-arrow-left-parc">zsg-arrow-left-parc</option>
<option value="zsg-arrow-right-parc">zsg-arrow-right-parc</option>
</select>
however the select2 container is not enabled and has the .select2-container-disabled class. If I update the post, that select works fine. In fact this whole field was working properly but possibly stopped working with a recent update?
