php – 仅在我的文本框中验证数字和字母

愉快的一天每个人..我在我的PHP文件中有这个java脚本代码,其中我使用它作为我的验证器…在我的文本框中的不同字段中的输入…我唯一的问题是我不知道如何创建验证只接受信件…在我的名字和姓氏字段…期待任何帮助感谢有一个美好的一天…我也想知道如何只在我的领域接受数字超级谢谢^^,

这是代码：

<script type='text/javascript'>

$(document).ready(function()
  {
       $('#employee_form').validate({
         submitHandler:function(form)
       {
          $(form).ajaxSubmit({
          success:function(response)
          {
             tb_remove();
             post_person_form_submit(response);
           },
        dataType:'json'
       });

   },

    errorLabelContainer: "#error_message_Box",
    wrapper: "li",
    rules: 
    {
        first_name: "required",
        last_name: "required",

        username:
        {
            required:true,
            minlength: 5
        },

        password:
        {
            <?PHP
            if($person_info->person_id == "")
            {
            ?>
            required:true,
            <?PHP
            }
            ?>
            minlength: 8
        },  
        repeat_password:
        {
            equalTo: "#password"
        },
        email:
        {               
            required:true,
            email: "email"
        }
    },
    messages: 
    {
        first_name: "<?PHP echo $this->lang->line('common_first_name_required'); ?>",
        last_name: "<?PHP echo $this->lang->line('common_last_name_required'); ?>",
        username:
        {
            required: "<?PHP echo $this->lang->line('employees_username_required'); ?>",
            minlength: "<?PHP echo $this->lang->line('employees_username_minlength'); ?>"
        },

        password:
        {
            <?PHP
            if($person_info->person_id == "")
            {
            ?>
            required:"<?PHP echo $this->lang->line('employees_password_required'); ?>",
            <?PHP
            }
            ?>
            minlength: "<?PHP echo $this->lang->line('employees_password_minlength'); ?>"
        },
        repeat_password:
        {
            equalTo: "<?PHP echo $this->lang->line('employees_password_must_match'); ?>"
        },

        email:
        {
            required: "<?PHP echo $this->lang->line('common_email_name_required'); ?>",
            email: "<?PHP echo $this->lang->line('common_email_invalid_format'); ?>"
        }

    }
   });
});
 </script>

解决方法:

只有字母：/ ^ [a-zA-Z] $/或/ ^ [a-z] $/ i

只有数字：/ ^ [0-9] $/
