PHP - 使用Get方法提交表单。

标签： javascript php html

我使用Get方法将用户输入的数据添加到数据库中的事件表中

您可以看到我使用get方法查看用户是否已发布然后运行代码 但if语句没有运行，我无法找出问题所在。

任何帮助都会有用

非常感谢

if(isset($_GET['add']))
{
    $title=$_POST['txttitle'];
    $detail=$_POST['txtdetail'];
    $eventdate=$month."/".$day."/".$year;
    $sqlinsert="INSERT INTO book (title, detail, eventdat, dateadded) VALUES ('{$title}', '{$detail}', '{$eventdate}',now())";
    $result = mysql_query($sqlinsert, $connect);
    if($result)
    {
        echo"date has been added";
    }
    else
    {
    echo "ops there was problem ";
    }
}

这是完整的代码 event.php

    include_once('db_connection.php');

这是事件表格

<form name="eventform" name="POST" action="<?php $_SERVER['PHP_SELF'];?>?month=<?php echo $month;?>&day=<?php echo $day;?>&year=<?php echo $year;?>&v=true&&add=true">
<table width="400px">
<tr>
<td width="150">Title</td>
<td width="250"><input type="text" name="txttitle"></td>
</tr>
<tr>
<td width="150">Detail</td>
<td width="250"><textarea name="txtdetail"></textarea></td>
</tr>
<tr>
<td colspan='2' align="center"><input type="submit" name"btnadd" value="Add Event"></td>
</tr>
</table>
</form>

PHP：

if(isset($_GET['btnadd']))
{
    $title=$_GET['txttitle'];
    $detail=$_GET['txtdetail'];
    $eventdate=$month."/".$day."/".$year;
    $sqlinsert="INSERT INTO book (title, detail, eventdat, dateadded) VALUES ('{$title}', '{$detail}', '{$eventdate}',now())";
    $result = mysql_query($sqlinsert, $connect);
    if($result)
    {
        echo"date has been added";
    }
    else
    {
    echo "ops there was problem ";
    }
}

和HTML：

<form name="eventform" method="GET" action="<?php $_SERVER['PHP_SELF']; ?>">
<table width="400px">
<tr>
<td width="150">Title</td>
<td width="250"><input type="text" name="txttitle"></td>
</tr>
<tr>
<td width="150">Detail</td>
<td width="250"><textarea name="txtdetail"></textarea></td>
</tr>
<tr>
<td colspan='2' align="center"><input type="submit" name"btnadd" value="Add Event"></td>
</tr>
</table>
</form>

method =“GET”会自动将变量添加到网址中，您无需在操作中添加变量。

您的代码中存在各种错误，但主要是您正在设置<form name="POST">。我相信您要设置<form method="POST">。

答案 2 :(得分：0)

首先，如果你去方法GET ..任何用户只需在发送后刷新页面，它就会破坏你的动作，因为如果它有一个GET方法表单，PHP会检查url表单。

另外，你的PHP代码似乎有点不对.. 

if(isset($_GET['add']))
{
    $title=$_POST['txttitle'];
    $detail=$_POST['txtdetail'];
    $eventdate=$month."/".$day."/".$year;
    $sqlinsert="INSERT INTO book (title, detail, eventdat, dateadded) VALUES ('{$title}', '{$detail}', '{$eventdate}',now())";
    $result = mysql_query($sqlinsert, $connect);
    if($result)
    {
        echo"date has been added";
    }
    else
    {
    echo "ops there was problem ";
    }
}

你的PHP正在检查是否有一个var，（array =“add”），所以检查你的表单中是否有一个名为“add”的输入，我想你正在尝试检查“btnadd”，因为你的提交按钮有这个名字。

您输入中有错误：

<input type="submit" name"btnadd" value="Add Event">

你没有输入“=”，所以应该是：

<input type="submit" name="btnadd" value="Add Event">

其中“btnadd”必须在你的PHP中

if(isset($_GET['btnadd']));//Exact var name
