Question

我得到了以下一段代码（为此问题目的缩写）

＆＃13;

    $(function() {
		var professions = [{"name":"Altenpflegehelfer","value":"3"},{"name":"Altenpfleger","value":"4"},{"name":"Änderungsschneider","value":"2"},{"name":"Anlagenmechaniker","value":"5"},{"name":"Anlagenmechaniker für Sanitär-, Heizungs- und Klimatechnik (früher: Zentralheizungs- und Lüftungsbauer)","value":"6"},{"name":"Asphaltbauer","value":"7"}];
		
        $('#profession').dropdown({
            values: professions,
            fullTextSearch: true,
        });

    });

问题是，当我发送表单时，PHP中的$ _REQUEST变量为空。

您只需使用以下内容创建新文件post.php即可对其进行测试：

<?php echo var_dump($_REQUEST); ?>

我做错了吗？
