Php 不显示JQuery UI自动完成搜索结果

我使用php从mysql数据库中没有得到任何搜索结果

PHP代码：

JQuery代码：

试试这个：

$("#search").autocomplete({
    source: "../searchclient.php",
    minLength: 1,
}).data("autocomplete")._renderItem = function(ul, item) {
    return $("<li>").data("item.autocomplete", item).append("<a>" + item.value + "</a>").appendTo(ul);
};

我沿着AJAX路线走，这似乎奏效了：

HTML

SEARCHCLIENT.PHP

我刚试过这个，不，它不起作用。这就好像数据没有从php返回到jquery中一样。是的，正如我提到的，当源代码硬编码到jquery中时，它会工作。但是，如果我想使用php查询数据库，例如source:/searchclient.php，即使php文件的输出是[{value:Hello World}，{value:East Meets West JV}]，它也不起作用。因此，我知道searchclient.php正在输出正确的数据，但它没有将其返回到jquery中。如果我直接转到localhost:9080/searchclient.php/？term=e，那么数据输出[{value:Hello World，id:1，label:Hello World}，{value:East Meets West JV，id:2，label:East Meets West JV}]。请参阅更新的PHP代码，我添加了ID和标签。您可以将代码放在任何服务器上吗。从那里我可以检查它。我的debug.log是说PHP注意：未定义的索引：C:\path中的term。因此，$q=$\u GET[term]这一行肯定有问题；你知道为什么会这样吗？
