Php 编辑时如何回显单选按钮的值

我知道以前有人问过这个问题。但我尝试了所有的解决方案，仍然无法获得输出。这就是我所做的：-（实际上，问题就在我的更新页面中）问题就在单选按钮上，我只希望单选按钮携带值，并用数据库中的值进行检查

更新_page.php

<?php
include("config.php");
$item_code= $_GET['item_code'];
$sel = mysql_query("select * from `table 14` where Item_Code='$item_code'");
$get_sel = mysql_fetch_array($sel); ?>
<script type="text/javascript" LANGUAGE="JavaScript">
function getting()
{
var agree=confirm("Confirm Update?");
if (agree)
document.myform2.submit2();

else
return false;
}
</script>
<center>
<h2 class="back" width='1400px'>Update Item Info</h2>

<div class="content">
<p style="margin-top:20px; font-size:20px;"><b><?php echo 
$get_sel['Item_Code']; ?></b></p>
<br />

<div id="main">

<form name="myform2" action="admin_update_process.php?item_code=<?php echo 
$get_sel['Item_Code'];?>" method="POST" >

你就快到了。看看这个，我刚刚对你的代码做了一些调整，包括回显
checked
属性


绿色文件（是/否）：
对
否



>否

if（$green_document=='YES'）{？>checked=“checked”您是否尝试了

if（$green_document=='YES'）{？>

@Naga是的，已经这样做了，但是仍然不能。你的实际问题还不清楚。你能提供一个你想要发生什么的例子吗？请解释一下。绿色文档从哪里来？为什么你有两套相同的收音机？流量是什么？你卡在哪里了？@NazirahAnwar哇，真的很难理解你r通过注释查看问题详细信息。请花时间通过编辑澄清您的问题。您是否需要输入标签上的

id

属性？您是否回显了

$green\u文档的值以确保其符合预期值？（请清除您的注释并更新您的问题）@令人难以置信的是，没有声明变量是正确的。请投票表决主题错误。不确定我为什么会出现此错误“分析错误：语法错误，意外'？” @jerome@IncredibleHat我试过了，但仍然无法获得输出。请有人帮助我。是的，我忘了删除
如果
。我已经编辑了答案，请check@NazirahAnwar我再次编辑了。Srry for inconvincience这一次我没有得到错误，但两个单选按钮都未选中@jerome
