我有一块代码，如下所示：
<td><?
$days = array("Sun","Mon","Tue","Wed","Thur","Fri","Sat");
for($i=1;$i<8;$i++)
{
echo $days[$i-1]?><input type="checkbox" name="labDays[]" value="<?=$days[$i]?>" checked="checked"><?
}?>
</td>
但是，当我运行print_r($_REQUEST['labDays']); 时
我得到Array ( [0] => [1] => [2] => [3] => [4] => [5] => [6] => )
我期待Array ( [0] => Sun[1] => Mon[2] => Tue[3] => Wed[4] => Thur[5] => Fri[6] => Sat)
我确信这是件愚蠢的事，但我不确定我错过了什么。。。
print_r($_REQUEST)呕吐：Array ( [pg] => 12 [msg] => Facility Already Exist [facilityname] => kjgkjhgkjhg [facorgtype] => [facilitytype] => [administratorsname] => [divisionname] => [streetaddress1] => [streetaddress2] => [city] => [state] => [zipcode] => [phonenumber] => [faxnumber] => [email] => [mainstate] => [labDays] => Array ( [0] => [1] => [2] => [3] => [4] => [5] => [6] => ) [facBillingContact] => [facBillingPhone] => [facBillingFax] => [facBillingRep] => [facBillingAccNum] => [facNotes] => [submit] => Create )
var_dump($_REQUEST['labDays']):
array
0 => string 'Sun' (length=3)
1 => string 'Mon' (length=3)
2 => string 'Tue' (length=3)
3 => string 'Wed' (length=3)
4 => string 'Thur' (length=4)
5 => string 'Fri' (length=3)
6 => string 'Sat' (length=3)
我相信这就是您想要的：
<?php
$days = array("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat");
foreach ($days as $day) {
echo <<<HTML
<label>$day
<input type="checkbox" name="labDays[]" value="$day" checked>
</label>
HTML;
}
?>
注意事项：
PHP
- 不建议使用简写语法（
<? ?>，尤其是<?= ?>） - 对于迭代数组，
foreach比for更适合 - 我对字符串使用PHP的heredoc语法。这样可以避免引号混淆
- 使用
$_POST或$_GET而不是$_REQUEST，这样会更安全
HTML
- 在HTML中为表单元素使用标签，这将文本与表单控件相关联，而且当您单击文本时，它也会标记相应的复选框
checked属性不需要任何值。它在那里就足够了
如果您想在数组中循环，foreach是的最佳选择
$days = array("Sun","Mon","Tue","Wed","Thur","Fri","Sat");
foreach($days as $k=>$v)
{
echo $k?><input type="checkbox" name="labDays[]" value="<?=$v?>" checked="checked"><?
}?>
使用for，您可以这样做：
$days = array("Sun","Mon","Tue","Wed","Thur","Fri","Sat");
for($i=0;$i<=6;$i++)
{
echo $i;?><input type="checkbox" name="labDays[]" value="<?=$days[$i]?>" checked="checked"><?
}?>
推荐的方式。。
$days = array("Sun","Mon","Tue","Wed","Thur","Fri","Sat");
foreach($days as $k=>$v)
{
echo $k . ' <input type="checkbox" name="labDays[]" value="'.$v.'" checked="checked">'; //you can give your styles and css ofcourse to make it better..
}
也许使用echo打印值：
<input type="checkbox" name="labDays[]" value="<?php echo $days[$i]; ?>" checked="checked">
