i am not getting any results when i search.
<input type="text" class="span1" id="tag_field" data-items='4' data-provide="typeahead" data-source='[<?php echo json_encode($groups); ?>]' >
<?php echo json_encode($groups); ?>
when i echo out json_encond($groups) it appears in this format
{"35":"biology","37":"economist","33":"programmers"}
if i type in the data source using this format i do get results.
data-source='["Alabama","Alaska","Arizona"]'>
我搜索时没有得到任何结果。
＆lt; input type =“text”class =“span1”id =“tag_field”data-items ='4'ata-provide =“typeahead”data-source ='[＆lt;？php echo json_encode（$ groups）; ？＆gt;]'＆gt;
＆lt;？php echo json_encode（$ groups）; ？＆gt;
当我回显出json_encond（$ groups）时，它会以这种格式显示
{“ 35“：”biology“，”37“：”经济学家“，”33“：”程序员“}
如果我使用这种格式输入数据源 我确实得到了结果。
data-source ='[“Alabama”，“Alaska”，“Arizona”]'＆gt;
I think the Typeahead plugin is expecting an Array of Strings as the data-source. Your json_encode is creating an Object and you're just wrapping it in an array when you echo it.
You want something like this:
微信扫一扫<?php
$groups = array("biology", "economist", "programmers");
?>
<input type="text" class="span1" id="tag_field" data-items='4' data-provide="typeahead" data-source='<?php echo json_encode($groups); ?>'>
You can use the array_values() function in PHP to ensure your $groups is a basic numerically indexed array.
