Hi guys,

That is Jquery Autocomplete:

<script>
      $(function() {
            var availableTags = [
                                    <? foreach ($product_autocomplete as $key => $value){?>
                                    "<?=$product_autocomplete[$key]['header'][$_lang]?>",
                                    <?}?>
            ];

            $( "#header_<?=$_lang?>" ).autocomplete({

                  source: availableTags
            });
      });
      </script>
My problem is that $product_autocomplete[$key]['header'][$_lang] may have identical(duplicated value). It would be great if autocomplete could be uniqe.

I know that in PHP, there is array_unique function, but if I use foreach (array_unique($product_autocomplete) as $key => $value, I can see only 1 autocompletion offering.

I corrected indentions, and some conventions :)

<?php
$items = array();
foreach ($product_autocomplete as $key => $value){
   $items[] = "\"".$product_autocomplete[$key]['header'][$_lang]."\"";
}
$items = array_unique($items);
?>
<script type="text/javascript">
      $(function() {
            var availableTags = [<?php echo implode(',',$items); ?>];

            $( "#header_<?php echo $_lang; ?>" ).autocomplete({

                  source: availableTags
            });
      });
</script>
