你的星座：
我想你见过使用这种方法的方法：
<input name="someField" type="text" value="<?php echo $_POST['someField']; ?>" />
您遇到了什么样的麻烦？你需要更具体一些才能得到有用的答案。@StephaneM我不完全确定我遇到的麻烦是不是问题所在。。。
<option selected="selected">someValue</option>
// Validate input
if($_POST['month'] != 3) //(Or some other validation check)
{
//Set the default month as January
$defaultMonth = 01;
}
else
{
// Input is valid, leave it as whatever the user set last time
$defaultMonth = $_POST['month']; //Don't do this without cleaning your input
}
// Define the different options to use in the select field
$months = array(
01 => 'January',
02 => 'February',
03 => 'March',
04 => 'April',
......
12 => 'December'
);
// "Create" the select field from the array above
echo '<select name="month" size="1">';
foreach($months as $monthNo => $desc)
{
// Decide if we want to put the selected="selected" line in
if($monthNo == $defaultMonth)
{
$selectedText = "selected='selected' ";
}
else
{
$selectedText = "";
}
echo "<option value='$monthNo' $selectedText>$desc</option>";
}
echo '</select>';
