html code as a value for textarea
提问by pastx
I am working on simple code editor and I have this simple HTML page:
我正在研究简单的代码编辑器,我有这个简单的 HTML 页面:
<div class="container">
<h1>Test</h1>
<p>Hello world !</p>
</div>
I need to create simple form that would allow me to edit this page and save changes, this is my code:
我需要创建允许我编辑此页面并保存更改的简单表单,这是我的代码:
<?php
$text = file_get_contents("test.html");
?>
<form method="POST">
<fieldset>
<textarea name="text" value="<?php echo $text; ?>" >
</textarea>
<button type="submit" class="btn">Send</button>
</fieldset>
</form>
Unfortunately this doesnt work right and it does not parse all html code as text , this is real value of textarea after runing script
不幸的是,这行不通,它不会将所有 html 代码解析为文本,这是运行脚本后 textarea 的真正价值
<h1>Test</h1>
<p>Hello world !</p>
</div>" >
It looks like it parsed div with class declaration as valid html code, not as text.
看起来它将带有类声明的 div 解析为有效的 html 代码,而不是文本。
Probably caused by "
.
大概是 引起的"
。
I also try this but result was exactly same:
我也试过这个,但结果完全一样:
<textarea name="text" value="<?php echo "<![CDATA[".$text."]]>"; ?>" >
Can anyone help me to get all content of html page as value of textarea ?
任何人都可以帮助我获取 html 页面的所有内容作为 textarea 的值吗?

You need to include your values between tags <textarea></textarea>
:
您需要在标签之间包含您的值<textarea></textarea>
:
<textarea name="text"><?php echo $text; ?></textarea>

try this
尝试这个
It simple this
这很简单
<textarea name="text" rows="10" cols="50"><?php echo $text; ?></textarea>
Here cols
and rows
are the attribute of textarea
.you can't place you
value in that place.you can place your value <?PHP echo $text;?>
in between <textarea></textarea>
这里cols
和rows
是的属性textarea
。你不能把你的值在place.you可以把你的价值<?PHP echo $text;?>
之间<textarea></textarea>
