Question

我希望使用jquery验证功能在数据库中验证发布可用性，我已经使用下面的代码进行了验证，在提交表单之前需要进行ajax验证

$(document).ready(function() {

  $("#conference_form").validate({
   rules: {
        postcode: "required",
         name: "required",
         address: "required",
         date: "required",
         description:"required",

    },
    messages: {
         postcode: "Please enter valid post code",
         name: "Please enter venu_name",
         address: "Please enter address",
         date: "Please enter date",
         description: "Please enter description",
    }
  })
});

请任何人帮助。

这是使用jquery validate在DB中进行邮政编码可用性检查的示例代码。

//Javascript
$(document).ready(function() {
    $("#conference_form").validate({
       rules: {
            postcode:  {
                required: true,     
                remote: {
                    url: "postalcode_availability.php",
                    type: "post",
                    contentType: "application/json; charset=utf-8",  
                    dataType:"json",
                    data: "{'postcode': '" + $('#postcode').val() + "'}",
                    dataFilter: function(data) {
                        var json = JSON.parse(data);
                        if(json.status == "true") {
                            return true;
                        }else{
                            return false;
                        }
                    }
                }           
              },
             name: "required",
             address: "required",
             date: "required",
             description:"required",

        },
        messages: {
             postcode: :{
                 required: "Please enter your postcode.",
                 remote: jQuery.validator.format("{0} is not exist.")
             },          
             name: "Please enter venu_name",
             address: "Please enter address",
             date: "Please enter date",
             description: "Please enter description",
        }
    })
});


//postalcode_availability.php
// For reference I have made check postal code in an array but you can make code for check in DB as per your requirement.
<?php       
    $postcodeArray = array('382481','382810','382845'); 

    $postcode=$_POST['postcode'];
    $isError = "";
    if (in_array($postcode, $postcodeArray))
    {       
        $isError "true"; //exist
    } 
    else
    {       
         $isError "false";  //Not exist
    }
    echo json_encode(["isError"=>$isError]);exit;
?>
