“编辑”按钮打开新窗口，允许编辑和使用PHP代码更新Sql Server
仍在学习PHP，因此这可能与其他类型相同，但存在问题。 我想在上一个屏幕上单击编辑，它将打开一个更新记录窗口（如下），当该窗口打开时，它将选择以前的标准，但允许用户更改记录。我在更新屏幕中有多个下拉列表，因为部门和内容正在从其他SQL Server表中提取。它不允许我将它们全部放在下拉列表中，以便在需要时为更新记录选择新标准 我只是不确定我可能需要使用的代码，因为起始记录页面是用php代码从sql server中提取的下拉菜单设置的，并且它可以工作。不确定当选择“编辑”以调出已选择的事务和条件时，为什么这不会从视图屏幕中调出信息“编辑”按钮打开新窗口，允许编辑和使用PHP代码更新Sql Server,php,sql-server,sqlsrv,Php,Sql Server,Sqlsrv,仍在学习PHP，因此这可能与其他类型相同，但存在问题。 我想在上一个屏幕上单击编辑，它将打开一个更新记录窗口（如下），当该窗口打开时，它将选择以前的标准，但允许用户更改记录。我在更新屏幕中有多个下拉列表，因为部门和内容正在从其他SQL Server表中提取。它不允许我将它们全部放在下拉列表中，以便在需要时为更新记录选择新标准 我只是不确定我可能需要使用的代码，因为起始记录页面是用php代码从sql server中提取的下拉菜单设置的，并且它可以工作。不确定当选择“编辑”以调出已选择的事务和条件时

如果$transaction\u id
的值为1；删除表事务？然后发送到服务器的SQL查询字符串如下所示：
从[Transaction]中选择*，其中Transaction_id=1；删除表事务
然后你会丢失所有的数据，我从
我建议使用PDO
来prepare
和execute
在PHP中执行查询，我在上面的代码示例中简要介绍了语法
现在，从这里开始，在您的旧代码中有一些东西没有真正意义，我将尽可能多地列出它们
将更新查询存储在名为$update
的变量中，然后使用名为$sql
的变量执行查询
$update = "update [Transaction] set
fund='" . $fund . "',
department='" . $department . "',
code_name='" . $code_name . "',
budget_year='" . $budget_year . "',
entry_date='" . $entry_date . "',
project_name='" . $project_name . "',
item_desc='" . $item_desc . "',
amount='" . $amount . "',
detail='" . $detail . "',
PO='" . $PO . "'
where transaction_id='" . $transaction_id . "'";
sqlsrv_query($conn, $sql);
最初，您在脚本开始时从DB获取事务，并将该行存储在名为$row
的变量中，然后在脚本中执行许多查询以获取信息，例如'Funding'，所有查询都将其结果存储到名为$row
的变量中，覆盖事务信息。在命名变量时要更加精确，这将使代码更易于阅读，也可以防止类似的错误
在select
循环中，您是否使用echo
两次？还要测试一下，$row['fund']=='Operational'
是否有两次
最后，我将简要地解释一下我的代码，这样您就可以完成剩下的部分了
首先，我们从$\u get
请求中获取事务ID，我们使用它从数据库中获取正确的行，并将结果存储在关联数组名$transaction
中，因此稍后在代码中，每当我们需要关于现有事务的信息时，我们都使用此变量
我刚刚将update语句更改为prepared语句，并添加了一个else来显示查询是否失败
我添加了一个结束select
标记，因为您的标记丢失了。对于基金和部门，我们做同样的事情，准备一份声明，将所有结果作为一个数组（适当命名）获取，然后通过它们foreach
。在foreach
的每次迭代中，我们将$row
的值与相应的$transaction
值（例如$transaction['fund']==$row['fund']
）进行比较，如果它们匹配，则将其选中！如果它们不匹配，则$selected
变量设置为空，因此对选项没有影响
这个答案比我预期的要长，可能遗漏了很多东西，但是如果你有任何问题，请把它们放在下面

更新事务
更新事务
@LiamG不确定我能不能带你去我有点不明白你的问题是什么？问题在于事务的更新吗？或者创建一个新的？更新当前的。比如说，输入时的详细信息和部门是错误的。我想点击编辑按钮打开更新屏幕，它有什么是原始输入，然后让我选择一个更新所需的字段。唯一的问题是下拉列表（资金、部门、目标代码、项目名称和预算年度都来自sql server中的表）。它不允许我像在原始输入表单中那样添加这些下拉列表，以从数据库中提取并更新事务表以显示更新的行。因此，在上一页，编辑按钮链接是这样的：editTransaction.php？id=25
@LiamG查看我的答案，看看你认为我没有正确解释。那么你需要编辑原始事务的所有字段吗？你应该在将来编辑你的原始问题。如果需要，我会给用户编辑所有字段的选项，但在编辑之前，我需要字段显示第一次输入的内容。我可能没有用最好的方式解释这一点。是的，我现在明白了，我现在在手机上，在接下来的14个小时内不会在我的电脑上，我会整理一个伪代码答案，然后在下次我在我的电脑上编辑它。听起来很好，谢谢你的帮助。需要与您取得联系以获得快速答复。。谢谢您如何在交易表中存储“资金”选项？有身份证吗？或者资金的名称？我一定是出了什么严重的问题，第四行给了我一个错误$事务_id=$_GET['transaction_id']；未定义的索引：事务\u idto
