I can´t seem to get the multiple select to display the selected = "selected"
attribute when saving or refreshing .
Everything works (db insert is OK, results output OK), but i can not get the selected values to show after refreshing .
I am trying to use the selected() function from the wp core ..
The code (it is inside a widget class and serves for a fairly simple widget ) :
<!-- List Custom Fields Hide Underscore (hide=no) -->
<p>
<?php $keys_no = $this->k99_cfsw_get_all_cf_array('no');?>
<?php if ( $keys_no ) { ?>
<label for="<?php echo $this->get_field_id('cfl2'); ?>"><?php _e('Select your custom field','k99_gelosa_domain'); ?></label>
<select multiple="multiple" class="chzn-select" style="width:150px;height:29px;" size="5" id="<?php echo $this->get_field_id('cfl2'); ?>" name="<?php echo $this->get_field_name('cfl2'); ?>[]" value="<?php $instance['cfl2'] ?>">
<option value="<?php isset($instance['cfl2']) ? _e($instance['cfl2']) : _e('#NONE#'); ?>"><?php isset($instance['cfl2']) ? _e('multiple') /*_e($instance['cfl2'])*/ : _e('#NONE#'); ?></option>
<!--<option value="#NONE#"><?php //echo $cfl; ?></option>-->
<!--<option value="------">-------</option>-->
<?php
foreach ( $keys_no as $key ) {
echo "n<option value='" .esc_attr($key) . "'". selected( $instance['cfl2'],esc_attr($key) ,FALSE).">". esc_html($key) . "</option>";
}
?>
</select>
<?php
} ?>
</p>
as a side note and a bonus question – , I am using also the chosen JS – it is also working ok, (except that it does not show the selected items ..) but have also a small bug that it will not initiate when the widget is closed – only after saving in an open state …
never-mind, found it , the answer is :
