变灰HTML表单元素
[英]Graying out HTML form elements
问题描述
I want to let the user select one "row" to use to submit the with to request a report type. 
我想让用户选择一个“行”以用于提交请求一个报告类型。 How can I put radio buttons in the first column of a table and whichever is selected is the active row that gets sent to the next page via the submit button? 如何将单选按钮放在表格的第一列中，而选中的哪个是通过“提交”按钮发送到下一页的活动行？

I think Andreas is on the right track, but it's not as useful as it could be. 我认为安德里亚斯（Andreas）处在正确的轨道上，但它没有发挥应有的作用。 This should be a bit better: 这应该更好一些：
<?php
blah ...
echo <<<HTML
<form action="handler.php" action="post">
<table>
HTML;
foreach ($rows as $row)
{
$id = $row['id'];
$text = $row['text']; // escape this unless you know it's safe
echo <<<HTML
<tr>
<td><input type="radio" value="$id" name="theRadioButton" /></td>
<td><input type="text" name="textfield_$id" value="$text" /></td>
</tr>
HTML;
}
echo <<<HTML
</table>
</form>
HTML;
form handler: 表单处理程序：
<?php
$id = isset($_POST['theRadioButton']) ? $_POST['theRadioButton'] : null;
if ($id)
{
$textfield = $_POST["textfield_$id"];
}
?>

If you want to do it in pure PHP, i guess you could do this: 如果您想用纯PHP做到这一点，我想您可以这样做：
<form action="ascript.php" action="post">
<table>
<tr>
<td><input type="radio" value="row1" name="theRadioButton" /></td>
<td><input type="text" name="row1textfield" /></td>
</tr>
<tr>
<td><input type="radio" value="row2" name="theRadioButton" /></td>
<td><input type="text" name="row2textfield" /></td>
</tr>
<tr>
<td><input type="radio" value="row3" name="theRadioButton" /></td>
<td><input type="text" name="row3textfield" /></td>
</tr>
</table>
</form>
ascript.php ascript.php
<?php
if ($_POST['theRadioButton'] == "row1") {
echo $_POST['row1textfield'];
// Handle row 1 ..
}
else if ($_POST['theRadioButton'] == "row2") {
echo $_POST['row2textfield'];
// Handle row 2 ..
}
else if ($_POST['theRadioButton'] == "row3") {
echo $_POST['row3textfield'];
// Handle row 3 ..
}
?>
However, if you're willing to use some jQuery, you could just name the textfields the same thing and disable the fields you're not going to use. 但是，如果您愿意使用某些jQuery，则可以将文本字段命名为相同的名称，并禁用将不使用的字段。 Here's a fiddle: http://jsfiddle.net/rrvQu/1/ 这是一个小提琴： http : //jsfiddle.net/rrvQu/1/
