希望有人能够帮助解决这个问题。我有一个表单，当您从下拉菜单中选择一个页面时，它应该使用数据库中的内容填充字段。这是有效的，但由于一些奇怪的原因，只是停了一夜。也许这是我做过的事情，没有意识到。源代码显示JavaScript从数据库获取所有内容并存储在数组中。但它没有根据PageId中的选择填充文本字段。
<?php /*
if(!isset($_SESSION['user']))
{
header("Location: login.php");
} */
//$vbCrLf = chr(13).chr(10);
$vbCrLf = "";
require ('dbconnect.php');
//create and execute query
$query = 'SELECT PageId, PageTitle, PageContent, PageContent2 FROM pages ORDER BY PageId';
$result = mysql_query($query) or die ('Error in query: $query. ' . mysql_error());
//create selection list
$DropDownList = "<select name='PageId' id='PageId' onchange='SelectChanged();'> ".$vbCrLf;
//$DropDownList .= "<option value=''>--SELECT PAGE--</option> ".$vbCrLf;
// this is unnecessary it will just give an error
while($row = mysql_fetch_row($result))
{
$heading = htmlentities($row[0]);
// dont need these so delete them
//echo "<p>\$heading=$heading</p>";
//echo "<p>\$row[1]=$row[1]</p>";

因此，从下拉列表中选择PageId时，它不会填充表单中的字段，而且应该填充。

答案 0 :(得分：1)
而不是，
DataSource使用，
DataField答案 1 :(得分：0)
您要做的是在textarea中提供文本。要做到这一点，你需要替换textarea代码：
<textarea
style="width:500px;height:200px;"
name="PageContent"
id="PageContent"
class="date"
value="<?php echo $row['PageContent']; ?>">
</textarea>
有了这个：
<textarea
style="width:500px;height:200px;"
name="PageContent"
id="PageContent"
class="date">
<?=htmlentities($PageContent)?>
</textarea>
您还可以看到代码已由http://stackoverflow.com的代码颜色系统更正。
htmlentities代码会对文本进行转义，因此如果内部有另一个</textarea>，则不会破坏代码。
此外，使用echo("");命令的一种简短方法是使用以下标记：<?=$variable?>或函数：<?=customFunction("hello")?>
setTimeout(SelectChanged(),400); // run this to set the first values in the select element
这将自动选择<select>元素中的第一个值。使用此代码，您真的不需要PHP代码来尝试设置值。
答案 2 :(得分：0)
OK so what you were trying to do is set the values, then load them. But you didn't know that the script has to be after the code you want to edit. Because or else it will execute before the table is created.
