问题描述

好吧,我有我的JSON字符串内置,但我不知道下一步该怎么做?

  $('#提交)。住(点击,函数(){

                变种dataString ='[';
                    $('TR#项目)不是(':第一')。每个(函数(){
                        。VAR指数= $('#项目TR')指数(本);
                        。VAR supp_short_ code = $(本).closest(TR)找到('。supp_short_ code')文本();
                        VAR project_ref = $(本).closest(TR)找到('project_ref。)文本()。
                        。VAR om_part_no = $(本).closest(TR)找到('。om_part_no)文本();
                        Var描述= $(本).closest(TR)找到(说明。)文本()。
                        。VAR cost_of_items = $(本).closest(TR)找到('。cost_of_items)文本();
                        。VAR cost_total = $(本).closest(TR)找到('。cost_total)文本();
                        dataString + ='{行:'+指数+',supp_short_ code:'+ supp_short_ code +',project_ref:'+ project_ref +', om_part_no:+ om_part_no +',描述:+原文+',cost_of_items:+ cost_of_items +',cost_total_td:+ cost_total +'}';
                    });
                    dataString + =']';

                $就
                    ({
                    键入:POST,
                    网址:order.php
                    数据:dataString,
                    缓存:假的,
                    成功:函数()
                        {
                            警报(订单提交);
                        }
                    });
            });
 

在我的PHP文件,我试图写dataString到一个文本文件,这样我就可以看到它的未来通过确定,但什么也没有在文本文件中!?我做得不对客户端或PHP端,我的PHP code:

 < PHP
    $ StringData是= $ _ POST ['dataString'];
    $ MYFILE =TESTFILE.TXT;
    $ FH =的fopen($ MYFILE,W)或死亡(无法打开文件);
    FWRITE($跳频,$ StringData是);
    fclose函数($ FH);
?>
 

解决方案

你为什么不尝试构建你的数据是这样

  VAR POSTDATA = {};
$('#项目TR')不是(':第一')。每个(函数(指数值){
    VAR键preFIX ='数据['+指数+];
    POSTDATA [键preFIX +'[supp_short_ code]'] = $(本).closest(TR)找到('supp_short_ code')文本()。
    POSTDATA [键preFIX +'[project_ref]'] = $(本).closest(TR)找到('project_ref。)文本()。
    // 等等
});
 

然后在你的AJAX调用

 数据:POSTDATA,
 

现在你的PHP脚本可以处理的数据作为多维数组

 < PHP
如果(使用isset($ _ POST ['数据'])及和放大器; is_array($ _ POST ['数据'])){
    的foreach($ _ POST ['数据']为$行=> $数据){
        回声$数据['supp_short_ code'];
        回声$数据['project_ref'];
        // 等等
    }
}
 

OK i've got my json string built but i'm not sure what to do next??

$('#submit').live('click',function(){ 

                var dataString = '[';
                    $('#items tr').not(':first').each(function(){
                        var index = $('#items tr').index(this);
                        var supp_short_code=$(this).closest('tr').find('.supp_short_code').text();
                        var project_ref=$(this).closest('tr').find('.project_ref').text();
                        var om_part_no=$(this).closest('tr').find('.om_part_no').text();
                        var description=$(this).closest('tr').find('.description').text();
                        var cost_of_items=$(this).closest('tr').find('.cost_of_items').text();
                        var cost_total=$(this).closest('tr').find('.cost_total').text();
                        dataString += '{"row":"' + index + '", "supp_short_code":"' + supp_short_code + '", "project_ref":"' + project_ref + '", "om_part_no":"' + om_part_no + '", "description":"' + description + '", "cost_of_items":"' + cost_of_items + '", "cost_total_td":"' + cost_total + '"}';
                    });
                    dataString += ']';

                $.ajax
                    ({
                    type: "POST",
                    url: "order.php",
                    data: dataString,
                    cache: false,
                    success: function()
                        {
                            alert("Order Submitted");
                        }
                    });
            });

In my php file i was attempting to write the dataString to a text file so i could see its coming through ok but nothing was in the text file!? Am i doing something wrong client side or PHP side, my php code:

<?php
    $stringData = $_POST['dataString']; 
    $myFile = "testFile.txt";
    $fh = fopen($myFile, 'w') or die("can't open file");
    fwrite($fh, $stringData);
    fclose($fh);
?>

解决方案

Why don't you try constructing your data like this

var postData = {};
$('#items tr').not(':first').each(function(index, value) {
    var keyPrefix = 'data[' + index + ']';
    postData[keyPrefix + '[supp_short_code]'] = $(this).closest('tr').find('.supp_short_code').text();
    postData[keyPrefix + '[project_ref]'] = $(this).closest('tr').find('.project_ref').text();
    // and so on
});

Then in your AJAX call

data: postData,

Now your PHP script can process the data as a multi-dimensional array

<?php
if (isset($_POST['data']) && is_array($_POST['data'])) {
    foreach ($_POST['data'] as $row => $data) {
        echo $data['supp_short_code'];
        echo $data['project_ref'];
        // and so on
    }
}
