回答1:

You can do that by using the select function of the plugin

$(document).ready(function() {
  $('#example-getting-started').multiselect();

  $('#example-getting-started').multiselect('select', ['cheese', 'pepperoni']);
});

From my understandingof your problem: You are using PHP to generate the select with its option and you retrieve the option and their selected/unselected state form a database. Your code snippet should be fine, Bootstrap Multiselect automatically preserves selected options (both in multiple and single mode). Note that in single mode (i.e. single selection through radio buttons) the last selected option is preselected in Bootstrap Multiselect, while in multiple mode all selected options will be preselected.

<?php $array = array("apple", "orange", "lemon"); ?>
<select> <!-- Note that the multiple attribute needs to be present to allow multiple selection. -->
<!-- Removed the empty option, not sure what it was for ... -->
<?php foreach ($array as $data): ?>
    <option value="<?php echo $data ?>" <?php if ($data == "orange") echo "selected=\"selected\""; ?>><?php echo $data ?></option>
<?php endforeach; ?>
<!-- Do not forget closing tag. -->
</select>

<script type="javascript/text">
$(document).ready(function() {
     // Will preselect "orange" in single selection mode ...
     $('select').multiselect({
         includeSelectAllOption: true
     });
});
</script>

After page load, the multiselect can be manipulated as described by lcycool.
