在 Phalcon Framework 的方法 find() 的条件下传递变量

Passing variable in conditions of method find() in Phalcon Framework

我在我的控制器中收到一个变量,我想用搜索变量进行绑定查询,我试试这个:

$search = $this->request->getPost('term');

                    $item = Item::find(
                            [
                                    'columns' => 'name',
                                    'conditions' => "name LIKE :searchT: ",
                                    'bind' => [
                                            'searchT' => '%'.$search.'%',  
                                    ],
                            ]
                            );

以上代码返回的项目不符合 LIKE 限制。

如果我按字面意思传递字符串就可以正常工作:

$item = Item::find(
                            [
                                    'conditions' => "name LIKE '%Os%' ",
                                    'columns' => 'name',
                                    'limit' => 10,
                            ]
                            );

JQuery:

<script type="text/javascript">
$( function() {
    $("#itemSearch").autocomplete({
        source: function ( request, response ) {
            $.ajax({
                type: "POST",
                url: "/item/search",
                dataType: "json",
                data: { 
                    term: request.term    
                },
                contentType: "application/json",
                success: function(data) {
                    response(data);
                }
            });
        },
        minLength: 2
    })
})
</script>

我的 $search 是空的,在我的 JQuery 中我需要在 ajax 中添加一个 header:

...
source: function ( request, response ) {
            $.ajax({
                type: "POST",
                headers: {
                    'Content-Type': 'application/x-www-form-urlencoded'
                },  
...
