使用 php 保存 SlickGrid 中的更改

发布于 2024-11-18 15:49:54 字数 476 浏览 8 评论 0原文

我设置了一个 SlickGrid，它正在使用 PHP 从我的数据库读取数据，当我尝试将数据保存回我的数据库时，我的问题出现了，我尝试使用 JSON 给我一个数组，然后我可以使用它写回数据库，我看到这个线程解释了这一点：

所以我具有隐藏的表单元素在我的代码中，我使用 JSON 对数据变量进行编码，将其分配给表单上的数据隐藏输入，此表单发布到名为 save_price.php 的页面，问题是当我 print_r 或 var_dump 数据变量时，我得到 null 作为输出，我认为这可能与我如何使用 PHP 将内容添加到数据变量有关，或者我正在做一些明显错误的事情，希望你能看到问题是什么，网上没有大量关于这方面的文档使用 PHP 检索/保存到数据库，所以我在这方面有点陷入困境，这是我的代码：

好吧，我发现了问题，以防万一有人努力让这一切正常工作，这是工作代码，它从数据库获取数据，然后将更改后的数据发送到另一个页面进行处理，它需要一些改进，一旦我全部实现，这就会发生：

<?php 
include("includes/check_session.php");
require_once('includes/functions.php');
require_once('includes/config.php');

$data = '';
$i = 0;

$query = "
    SELECT * FROM `prices`";
$result = mysql_query($query);
while($row = mysql_fetch_array($result, MYSQL_ASSOC)){
    $data .= '
        data['.$i.'] = {
            id: "'.$row['id'].'",
            title: "'.$row['title'].'",
            duration: "'.$row['duration'].'",
            percentComplete: "'.$row['percentComplete'].'",
            start: "'.$row['start'].'",
            finish: "'.$row['finish'].'",
            effortDriven: "'.$row['effortDriven'].'"
        };
    ';

    $i++;

echo $data;
}

?>

Ok so I found the problem, just incase anyone is struggling to get this all to work, here is the working code, it gets data from a database, then sends the changed data to another page for processing, it nees a little bit of refinements, that will happen once I've got it all implemented:

<?php 
include("includes/check_session.php");
require_once('includes/functions.php');
require_once('includes/config.php');

$data = '';
$i = 0;

$query = "
    SELECT * FROM `prices`";
$result = mysql_query($query);
while($row = mysql_fetch_array($result, MYSQL_ASSOC)){
    $data .= '
        data['.$i.'] = {
            id: "'.$row['id'].'",
            title: "'.$row['title'].'",
            duration: "'.$row['duration'].'",
            percentComplete: "'.$row['percentComplete'].'",
            start: "'.$row['start'].'",
            finish: "'.$row['finish'].'",
            effortDriven: "'.$row['effortDriven'].'"
        };
    ';

    $i++;

echo $data;
}
