我有一个应用程序，用户可以在其中将请求编辑发送给管理员，现在的问题是如何将请求资产的ID从user_asset表存储到请求表中，以便我可以将其显示在管理员页面上，并提供完整的详细信息资产
当用户单击请求编辑时，他会得到一个带有可编辑字段的表单，其中填充了当前信息，但是我如何存储此资产的 id ，这样我就可以将两者的信息都提取到管理员的表中表（（用户资产，请求）
我有 user_asset表
asset_id
asset_category
code
title
userid
和请求表
id
reason
assetid
user_id
这是我到目前为止所做的
if(isset($_POST['submit'])){
// get all values from input with no special charactere
$code = mysqli_real_escape_string($conn, $_POST['code']);
$asset_id = mysqli_real_escape_string($conn, $_GET['id']);
$reason = mysqli_real_escape_string($conn, $_POST['reason']);
if (!$error) {
if (!$error) {
// execute the sql insert
if(mysqli_query($conn, "INSERT INTO `requests`(id,reason,assetid, user_id)
VALUES( null, '" . $reason . "', '". $asset_id ."','" .$_SESSION['user_id'] . "')")) {
// if the insert result was true (OK)
$success_message = "req was successfully added ! ";
} else {
// if the insert result was false (KO)
$error_message = "Error in data...Please try again later!";
}
}
}
}
else{
if(isset($_GET['idedit']) ){
$result = mysqli_query($conn, "SELECT * from user_asset WHERE asset_id=".$_GET['idedit']);
$project = mysqli_fetch_array($result);
}
}
?>
这是我的表格
<form method="post" action="req_ade.php" id="adding_new_assets">
<div class="control-group">
<label for="basicinput">الکود : </label>
<div class="controls">
<input type="number" id="basicinput" value="<?php echo $project['code']; ?>" placeholder="الكود" name="code" class="span8">
</div>
</div>
<div class="control-group">
<label for="basicinput">التفاصيل : </label>
<div class="controls">
<input type="text" id="basicinput" value="<?php echo $project['title']; ?>" placeholder="التفاصيل" name="title" class="span8">
</div>
</div>
<div>
<label style="color:black">السبب</label>
<textarea rows="8" cols="8" name="reason" class="form-control" placeholder="اذكر سبب التعديل ..." ></textarea>
</div>
<div class="control-group">
<div class="controls">
<button type="submit" name="submit" class="btn">طلب تعديل</button>
</div>
</div>
</form>
这些是我得到的错误

注意：未定义索引：第28行的D：\ wamp64 \ www \ Caprabia-test \ req_ade.php中的ID
$ _ GET数组中没有“ id”。因此，您的$ asset_id变量将为空，并且空字符串不是有效的整数。您应该在查询中添加（int）
mysqli_query($conn, "INSERT INTO `requests`(id,reason,assetid, user_id)
VALUES( null, '" . $reason . "', '". (int)$asset_id ."','" .$_SESSION['user_id'] . "')")
或者最好在使用$ _GET数组之前检查一下。像这样：
If(isset($_GET['id']))
{
$asset_id = mysqli_real_escape_string($conn, $_GET['id']);
}
else
{
...
}

感谢您的所有建议。
尝试了很多建议并使用了代码后，我找到了解决方案。
if(isset($_POST['submit'])){
// get all values from input with no special charactere
$code = mysqli_real_escape_string($conn, $_POST['code']);
$asset_id = mysqli_real_escape_string($conn, $_POST['asset_id']);
$reason = mysqli_real_escape_string($conn, $_POST['reason']);
if (!$error) {
if (!$error) {
// execute the sql insert
if(mysqli_query($conn, "INSERT INTO `requests1`(id,reason,assetid, user_id)
VALUES( null, '" . $reason . "', '". $asset_id ."','" .$_SESSION['user_id'] . "')")) {
// if the insert result was true (OK)
$success_message = "req was successfully added ! ";
} else {
// if the insert result was false (KO)
$error_message = "Error in data...Please try again later!";
}
}
}
}
else{
if(isset($_GET['idedit']) ){
$result = mysqli_query($conn, "SELECT * from user_asset WHERE asset_id=".$_GET['idedit']);
$project = mysqli_fetch_array($result);
}
}
这是我以隐藏类型发布 asset_id 的表格
<form method="post" action="req_ade1.php" id="adding_new_assets">
<div class="control-group">
<label for="basicinput">الکود : </label>
<div class="controls">
<input type="hidden" value="<?php echo $project['asset_id'];?>" name="asset_id" />
<input type="number" id="basicinput" value="<?php echo $project['code']; ?>" placeholder="الكود" name="code" class="span8">
</div>
</div>
<div class="control-group">
<label for="basicinput">التفاصيل : </label>
<div class="controls">
<input type="text" id="basicinput" value="<?php echo $project['title']; ?>" placeholder="التفاصيل" name="title" class="span8">
</div>
</div>
<div>
<label style="color:black">السبب</label>
<textarea rows="8" cols="8" name="reason" class="form-control" placeholder="اذكر سبب التعديل ..." ></textarea>
</div>
<div class="control-group">
<div class="controls">
<button type="submit" name="submit" class="btn">طلب تعديل</button>
