Setting value of a HTML form textarea?
提问by Skizit
I'm using the following to set the value of a text area..
我正在使用以下内容来设置文本区域的值..
<?php
$message = $_REQUEST['message'];
?>
<br/><b>Description</b><br/>
<TEXTAREA NAME="message" COLS=40 ROWS=6 value="<?=$message;?>"></TEXTAREA><br/><br/>
<input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
but it doesn't appear to be working. The value of message is not null. Does anyone have any idea why it's not filling the value?
但它似乎不起作用。消息的值不为空。有谁知道为什么它没有填充价值？

Textarea has no value. You need to insert your message between the opening and closing tags.
文本区域没有价值。您需要在开始和结束标记之间插入您的消息。
<textarea><?php echo htmlspecialchars($message); ?></textarea>

<textarea name="message" cols="40" rows="6"><?=$message?></textarea>
Note:Make sure $messageis properly sanitized and that short_open_tagis enabled. Otherwise, @fabric's accepted answer is a better answer.
注意：确保$message已正确消毒并short_open_tag已启用。否则，@fabric 接受的答案是更好的答案。

Also you can use this method...
你也可以用这个方法...
`<textarea rows="12" id="mytextarea"><?php echo $bio; ?> </textarea>
<script>
document.getElementById(`mytextarea`).innerHTML="Include the text you want to display";
</script>`
