Question

我希望以一种形式获取文本框的$ _POST值。

文本框的名称会根据与之关联的用户而更改。

<input type='text' name='$tmpUsername.mondstart' value='$tmpmonStart' placeholder='Start' size='3' maxlength='5'>

即。 name will = bing.lee.mondstart

我尝试过使用：

$tmp = $tmpUsername . $_POST['mondstart']
$tmp = $_POST[$tmpUsername . 'mondstart']

谢谢。

完整源代码：

echo "<form name='employeehours' method='post' action='../path/'>\n";
echo "<table align=center width=210 border=0 cellpadding=7 cellspacing=0 id='createformtable'>\n";



while ($row=mysql_fetch_array($result)){

$timeformat = "hh:mm";
$tmpUsername = $row['Username'];
$tmpmonStart = substr($row['monStart'], 0, 5);
$tmpmonStop = substr($row['monStop'], 0, 5);
$tmptueStart = substr($row['tueStart'], 0, 5);
$tmptueStop = substr($row['tueStop'], 0, 5);
$tmpwedStart = substr($row['wedStart'], 0, 5);
$tmpwedStop = substr($row['wedStop'], 0, 5);
$tmpthuStart = substr($row['thuStart'], 0, 5);
$tmpthuStop = substr($row['thuStop'], 0, 5);
$tmpfriStart = substr($row['friStart'], 0, 5);
$tmpfriStop = substr($row['friStop'], 0, 5);
$tmpsatStart = substr($row['satStart'], 0, 5);
$tmpsatStop = substr($row['satStop'], 0, 5);
$tmpsunStart = substr($row['sunStart'], 0, 5);
$tmpsunStop = substr($row['sunStop'], 0, 5);

if ($_SERVER["REQUEST_METHOD"] == "POST") {
$updateUsers = $_POST['users'];

foreach($updateUsers as $user){
var_dump($user);
$tmp = $_POST[$user . '.mondstart'];

//$tmp =  $_POST[$user.'mondstart'];
echo $tmp;

echo $user;

}

Answer 1

取决于是否为数组。如果它们是字符串，请尝试使用连接赋值运算符。

foreach($updateUsers as $user){

$tmp = $user;
$tmp .= $_POST['mondstart'];

echo $tmp;
}

此外，

$tmp = $user . $_POST['mondstart'];

应该有效。但如果你需要一个空格，

$tmp = $user." ".$_POST['mondstart'];

如果其中一个是数组，则需要使用implode()。

Answer 2

假设name属性正确并且与源中的name='bing.lee.mondstart'类似（请确保通过浏览器查看页面的来源），您缺少点在$_POST变量中。因此，请尝试使用以下语句：

$tmp = $_POST[$tmpUsername . '.mondstart'];

$tmp变量将具有您需要的值。
