Question

您的建议中的新代码（仍然没有工作）我试图通过post方法从注册表单到php页面获取值，然后在该页面中回显它，所以我知道它有效。如果是这样，我将尝试获取所有值并将它们插入到我的用户表中。我不介意sql注入风险，我现在必须清理输入，我只想让它工作。但它没有，你们看到我做错了什么？也可以改为获取数组中的所有值并发布它们，这样我就不必使用这么多变量。

process.php (another page)
<?php print_r($_POST);?>

Answer 1

您可以使用元素名称获取值。所有值都在$_POST Array.Just print_r($_POST)内。您将看到所有发布的值。

在process.php;

extract($_POST);
echo $name;//prints name
echo $email;//prints email

extract()函数将变量从数组导入到本地符号表中。此函数使用数组键作为变量名称和值作为变量值。对于每个元素，它将在当前符号表中创建一个变量。

Answer 2

您可以使用<?php print_r($_POST); ?>来确切地检查传递给php的内容。这将显示从表单传递的所有变量及其值。

另外值得注意的是，表单只传递具有有效名称属性的输入。

Answer 3

我认为，这个示例代码会对您有所帮助。运行我的代码并在代码中使用这个想法。

in form.php

<form class="form" method="post" action="process.php"> 

<input type="text" name="name[]" value="a"/>
<input type="text" name="name[]" value="b"/>
<input type="text" name="name[]" value="c"/>

<label>Skapa Konto &nbsp;&nbsp;&nbsp;<input  type="submit" ></label>

in process.php

<?php
$nvals = count($_REQUEST['name']);
 // do something with $_REQUEST['name'][$i] for example
 echo 'Hello ' . $_REQUEST['name'][1] . '!'; 
?>

它将打印出“你好b！＆＃39;

”

如果你想使用for循环获取所有值，请使用此代码。

<?php 
$nofval = count($_REQUEST['name']);
for ($i = 0; $i < $nofval; $i++) {
   echo 'Hello ' .$_REQUEST['name'][$i] . '!';
}  
?>

在php页面中回显输入字段值
