Value attribute in textarea bootstrap 3
提问by Nick lK
I have a textarea I use as a form on a website.
我有一个 textarea 用作网站上的表单。
I usually use place "placeholder" text inside, but I need this information to come up editable.
我通常在里面使用地方“占位符”文本，但我需要这些信息来编辑。
What I used to do was just feed info from my database into the "value" attribute of the form. The form would then just pop up with my data, ready to be edited.
我过去所做的只是将数据库中的信息输入到表单的“ value”属性中。然后表单会弹出我的数据，准备好进行编辑。
For some reason though its not working with my textarea!
出于某种原因，尽管它不适用于我的 textarea！
Here is my code:
这是我的代码：
<textarea value='<?php echo $info?>' class="form-control" id="message" name="message" rows="5"></textarea>
I know its not the data because iv echoed it elsewhere and its fine. I also tried
我知道它不是数据，因为 iv 在其他地方回应了它并且很好。我也试过
<textarea value='hi' class="form-control" id="message" name="message" rows="5"></textarea>
with nothing showing up.
什么都没有出现。
Whats going on ? I used to do this all the time. Im using bootstrap 3, could it have something to do with that ?
这是怎么回事 ？我曾经一直这样做。我正在使用引导程序 3，它可能与此有关吗？
