我正在使用PHP构建预订系统，需要输出一系列可用于以日历格式预订的预订系统。用户只能在表单中选择一次，所以我需要它们作为单选按钮。我已经把它输出了可用的时间很好，但我不能在任何时候选择除第一个单选按钮之外的任何东西。
我认为这可能会有所帮助 - Only one (the first) radio button in a group is selectable / active因为这个想法是一样的，但解决方案是我没有的CSS问题。
下面的$ timeArray是存储的可用时间数组，例如2014-05-05-01,2014-05-05-02,2014-05-06-01。每个元素的最后两位数指的是当天的时间段。
<?php
for($i=0;$i<count($timeArray); $i++){ ?>
<input type="radio" name="request" id="request<?php echo $timeArray[$i]; ?>" value="<?php echo $timeArray[$i];?>" />
<?php } ?>
它会输出一系列时间和单选按钮，但我只能在日历的每一天选择第一个单选按钮。
由于只有一个值来自整个表单，我将名称保留为'request'。这是正确的吗？我已经尝试过了
request[]
和
request[$i]
没有任何区别，也尝试了
request[<?php echo $timeArray[$i]; ?>]
这使得所有按钮都可以选择，因为它们都有不同的名称。
你能指出我正确的方向吗？这是日历代码：
<table width="100%" align="center">
<tr valign="baseline">
<td valign="top" nowrap="nowrap" align="center"><?php
//set variables to today
$day = date('d');
$month = date('m');
$year = date('Y');
$monthCount = 0;
for($monthCount = 0; $monthCount <3; $monthCount++){
if ($month <= (date('m')+1)){
//first day of the month
$first_day = mktime(0,0,0,$month, 1, $year) ;
//month name
$title = date('F', $first_day) ;
$day_of_week = date('D', $first_day) ;
//determine how many blank days needed before the first day of the month
switch($day_of_week){
case "Sun": $blank = 0; break;

}
//how many days in the current month
$days_in_month = cal_days_in_month(0, $month, $year) ;

答案 0 :(得分：2)
你遗漏了一个属性的引用：
<input type="radio" name="request" id="request<?php echo $timeArray[$i]; ?> value="<?php echo $timeArray[$i];?>
^^^^^^
