我想用HTML和PHP編寫一個粘性選擇框。我希望提交之前用戶輸入的選擇在按下提交後突出顯示。我嘗試了幾種不同的方式，似乎並不奏效。現在我有這條線。粘性選擇框
<select name="selectBox[]" multiple="multiple" size="5">
<?php
$i=0;
while($temp=mysql_fetch_array($result,MYSQL_NUM))
{
//echo $temp[1];
?>
<option value="<?php echo $temp[1] ?>"
<?php if(isset($_POST[$temp[1]])) {echo "selected";} ?> >
<?php echo $temp[1] ?> </option>
<?php
$i++;
}
?>
</select>
我知道echo "selected"作品，因爲我曾經使用過，在選項標籤試了一下。
這裏是選擇標籤中的選項標籤略有不同的整個代碼，但它仍然不用擔心。
<html>

$myTable2='businesses';
$myTable3='biz_categories';
//connect to the database server.
$con=mysql_connect($DBserver,$user,$password);
$con or die('Could not connect to MySQL: ' . mysql_error());//check connection
mysql_select_db($myDatabase) or die("Unable to select database");//select the databse we will be using
//check selection
$result = mysql_query("SELECT * FROM $myTable1");//gets the category table.... we will use the fetch_array and take the 2nd element of the array for select box
$submitted=$_POST['submitted'];
if($submitted)
{
$sql="INSERT INTO $myTable2 (name, address, city, telephone, url) VALUES ('$_POST[bis_name]', '$_POST[addr]', '$_POST[city]', '$_POST[tele]' , '$_POST[url]')";
mysql_query($sql, $con) or die('Error dude: ' .mysql_error());
// echo "$_POST[bis_name]";

$chosenTitles=$_POST[selectBox];

foreach ($chosenTitles as $temp)//will run through each title chosen
{
//echo "$temp";//for testing

$catTitle2IDtemp=mysql_query("SELECT * FROM $myTable1 WHERE title='$temp'", $con);
$catTitle2ID=mysql_fetch_array($catTitle2IDtemp, MYSQL_NUM);

我認爲這將有助於你削減代碼示例，以消除行，你肯定是不相關的這個特定的問題。 –
上面的部分是底部是整個頁面的情況下的相關部分，以防有人想看整個圖片。特別是<選項標記 –
