使用Post Button更新表行值
[英]Update Table Row Value with Post Button
问题描述
我在我的mysql数据库中有一些数据，我使用PHP在表中显示如下所示
$requirement_qry="SELECT t1.*, t2.id as unit_id, t2.name as unit_name FROM `tbl_requirements`
t1 INNER JOIN tbl_units AS t2 on unit_type = t2.id AND project_id='".$_GET['project_id']."' AND user_id='".$userid."'";
$requirement_result=mysqli_query($mysqli,$requirement_qry);
<form action="" name="addeditcategory" method="post" class="form form-horizontal" enctype="multipart/form-data">
<input type="hidden" name="project_id" value="<?php echo $_GET['project_id'];?>" />
<div class="section">
<div class="section-body">
<div class="form-group">
<label class="col-md-3 control-label" >Project Name :-</label>
<div class="col-md-6">
<input type="text" name="name" id="name" value="<?php if(isset($_GET['project_id'])){echo $row['name'];}?> " class="form-control" disabled>

<option value="1" <?php echo $row['status'] == '1' ? 'selected' : ''; ?> >Open</option>
<option value="2" <?php echo $row['status'] == '2' ? 'selected' : ''; ?> >Closed</option>
</select>
</div>
</div>

echo '<tr>

$no++;

上面的代码正确显示我的数据。 我需要使用提交按钮更新行中的一个字段值。 如果只有一行，它的工作正常...如果有多行，它不会更新它的数据，除了最后一行。 我的提交代码如下所示
if(isset($_POST['submit']) and isset($_POST['project_id']))
{
$projectId = $_GET['project_id'];
$data = array(
'unit_received' => $_POST['received']
);
$unit_edit=Update('tbl_requirements', $data, " WHERE id = '".$_POST['reqId']."'");
print_r($unit_edit);
echo $unit_edit;
if ($unit_edit > 0)
{
$_SESSION['msg']="11";
header( "Location:view_open_project.php?project_id=".$_POST['project_id']);
exit;
}
}
我是PHP的新手，让我知道是否有人可以帮助我解决这个问题。 非常感谢 ：）

正如@Saji已经说过的那样，你正在通过循环复制你的名字。你应该使用
echo '<input type="hidden" name="reqId[]" id= "reqId" value="'.$id.'" />';
请注意附加的[]括号，以便创建名称数组。 要更新，你需要一个循环
for($i=0;$i<count($_POST['reqId']);$i++){
$unit_edit=Update('tbl_requirements', $data, " WHERE id = '".$_POST['reqId'][$i]."'");
}

你可以做的只是创建一个隐藏的表单，你将保留原始元素。 单击保存按钮时，只需找到实际值并将其设置为隐藏表单中的元素，然后触发隐藏表单中的提交按钮。
请注意我对您的代码所做的更改。
1.从内部循环中reqId隐藏元素reqId 。
2.给循环内的按钮指定一个类名，并将按钮类型从submit更改为button 。 添加了数据属性data-id="'.$id.'" 。
3.循环内部received输入通过连接$id给出了唯一的id和名称。
4.处理隐藏的表格，隐藏输入。 它有你的实际输入名称。
5.处理一个jquery函数，将click事件附加到循环内部的按钮。
6.将隐藏元素project_id到隐藏表单内部。
现在查看以下代码以获取更多详细信息。 希望这个能对您有所帮助..

如果在 html 表中选中复选框，那么我想在按下更新按钮时更新该行的值
[英]if checkbox is checked in html table then i want to update the value of that row when update button is pressed
if value table 1 row = 'confirm' and value table 2 row='Not sent' 显示按钮
[英]if value table 1 row = 'confirm' and value table 2 row='Not sent' show button
