我们可以发送的ID文件本身与提交表单

Question

我试图文章ID本身文件中的PHP。但它张贴什么。此代码我尝试

//if can it should echo 1 and point 232
<?php 
   if ($_POST['submit'] == 'winners') {
     $a = $_GET['A'];
     echo $a;

     $point = $_GET['POIN'];
     echo $point;
   }
?>

<form enctype="multipart/form-data" method="post" style="width:auto;">
    <div class="box">
        <span class='odometer' id="timespan" name="timespan">232</span>
    </div>
    <input class="process" name="submit" type="submit" id="submit" value="winners" onclick="location.href='reward-pollingx.php?A=1&POIN='+document.getElementById('timespan').innerHTML'">
</form>

Answer 1

你想用JavaScript来获得PHP中跨度值。尝试是这样的：

<?php

 $a = isset( $_GET['A'] ) ? $_GET['A'] : '';
 echo $a;
 $point = isset( $_GET['POIN'] ) ? $_GET['POIN'] : '';
 echo $point;

?>

<form enctype="multipart/form-data"  method="post" style="width:auto;">

    <div class="box">
        <span class='odometer' id="timespan" name="timespan">232</span>
    </div>

    <input 
    class="process" 
    name="submit" 
    type="submit" 
    id="submit" 
    value="winners" 
    onclick="window.location='reward-pollingx.php?A=1&POIN='+document.getElementById('timespan').innerHTML;return false;"
    >

</form>

Answer 2

如果你试图通过参数，如查询字符串，你不需要使用的一种形式。

因为您配置表单发送POST请求，您可以通过查询字符串参数隐藏式的输入值。测试如下

<form action="reward-pollingx.php" enctype="multipart/form-data" method="post" style="width:auto;">
    <input type="hidden" name="A" value="1">
    <input type="hidden" name="POIN" value="">
    <input type="hidden" name="submit" value="winners">

    <div class="box">
        <span class='odometer' id="timespan" name="timespan">232</span>
    </div>
    <input class="process" name="submit" type="submit" id="submit" value="winners">
</form>

<script>
    document.querySelector('input[name=POIN]').value = document.getElementById('timespan').innerHTML;
</script>

你的PHP代码应该改变使用$ _POST而不是$ _GET

<?php

if ($_POST['submit'] === 'winners') {
    $a = $_POST['A'];
    echo $a;

    $point = $_POST['POIN'];
    echo $point;
}

或者使用查询字符串参数传递给PHP脚本

<a href="reward-pollingx.php?submit=winners&A=1&POIN=...">Submit</a>

而PHP

if ($_GET['submit'] === 'winners') {
    $a = $_GET['A'];
    echo $a;

    $point = $_GET['POIN'];
    echo $point;
}

要构建查询字符串，因为你需要从视图中获取信息，你可能需要动态地生成它

如果您需要将表格提交到自身，您可以使用

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST" ....

或者您可以使用：

<form action="<?php echo $_SERVER['REQUEST_URI']; ?>" method="POST" ....
