Question

我有一个非常类似于此线程中的服务：

Php: Form auto-fill using $_SESSION variables with multiple php files

我会问那里，但由于我没有50点声望，我不得不问一个新问题。

为了更好地理解Ajax，我想重新创建rkmax文件并查看它们是否可行。所以我将它们保存为5个单独的文件。

SESSION似乎没有存储任何发布的信息。添加了print_r($_SESSION);以跟踪当前所在的内容。此外，通过电话号码检索帐户信息的.blur事件也不起作用。

这个人已经把头撞到墙上好几天了。当通过Apache / XAMPP本地托管或在实际的Web服务器上工作时，它不会工作。所有5个文件都在同一个文件夹中，标题与rkmax的文件标题完全相同。

我理解每个功能背后的逻辑，似乎无法在任何地方找到问题。我对编码很陌生，所以它很容易就像文件结构或我自己的计算机设置一样明显？

阅读其他一些具有类似问题的StackOverflow线程，但它们似乎都不适用。

感谢您的时间。

这里是从rkmax的代码中复制的所有内容：

if (!isset($_SESSION['customers'])) {
    $_SESSION['customers'] = array(
        '1234567' => '{"lname": "Berg", "mi": "M", "fname": "Thomas", "account": "1234"}',
        '1122334' => '{"lname": "Jordan", "mi": "C", "fname": "Jacky", "account": "4321"}',

Answer 1

我会尝试做一些缩小的事情，看看这是不是你想要做的。您只需要3页，原始表单页面，php页面和js文件：

<强> /ajax/dispatch.php

/*
**  @param $phone [string] Gets key from session
*/
function getCustomerByPhone($phone)
    {
        if(!empty($_SESSION['customers'][$phone])) {
            // I am decoding, but if you have the ability to set,
            // create an array like below with success and data
            $values =   json_decode($_SESSION['customers'][$phone]);
            die(json_encode(array("success"=>true,"data"=>$values)));
        }
    }

function makeError()
    {
        // Send back error
        die(json_encode(array("success"=>false,"data"=>false)));
    }
/*
** @param $array [string] This will be a query string generated from the
**                        jQuery serialize, so it's to be turned to array
*/    
function updateSession($array)
    {
        // This should come back as a string, so you will need to parse it
        $data   =   false;
        parse_str(htmlspecialchars_decode($array),$data);
        // Update the session
        $_SESSION['customers'][$data['phone']]  =   json_encode($data);
        die(json_encode(array("success"=>true,"data"=>$data)));
    }

if(isset($_POST['phone'])) {
    // If already exists, return to ajax the data
    getCustomerByPhone($_POST['phone']);
}
elseif(isset($_POST['data'])) {
    updateSession($_POST['data']);
}

// If not exists, return false
makeError();

<强> /scripts.js

// I try not to duplicate things as much as possible
// so I would consider making an object to reuse
var AjaxEngine  =   function($)
    {
        this.ajax   =   function(url,data,func,method)
            {
                method  =   (typeof method === "undefined")? 'post' : 'get';
                $.ajax({

                        func(response);
                    }
                });
            };
    };

$(document).ready(function(){
    // Create instance
    var Ajax        =   new AjaxEngine($);
    var dispatcher  =   '/ajax/dispatch.php';

                    return false;
                }
                // If there is a hit in session
                else if(resp.success == true) {
                    // Loop through it and fill empty inputs in form
                    $.each(resp.data, function(k,v){
                        var input   =   $("input[name="+k+"]");
                        if(input.length > 0) {
                            if(input.val() == '') {
                                input.val(v);
                            }
                        }
                    });
                }

                Ajax.ajax(dispatcher,
                    // This time send an action
                    // (just to differentiate from check function)
                    {
                        "action":"update",
                        "data":thisForm.serialize()
                    },
                    function(response) {
                        // Check your console.
                        console.log(response);
                });
        });
    });
});

Answer 2

从头开始，我的答案几乎是不间断的，但很快就要开始工作了，这是我迄今为止所得到的;我目前仍然成功地将SESSION数据发送回javascript并对其进行解码并成功显示。一旦我完成了这项工作，我认为将它们发送到适当的表格以及POST将是微不足道的。如果有人有任何建议来加速我通过这最后一部分，我将不胜感激。
