How to put PHP content into an iframe?

Question

I have an iframe and I want to put PHP content in it like in a text-area.

<textarea><?php echo $content; ?></textarea>

But it does not work for an iframe. How can I solve it?

Code:

<form action="php_parsers/article_parser.php" id="writearticle" name="writearticle" method="POST"> <p style="text-align: center; font-size: 22px;">Create Article</p> <textarea name="title" id="title" type="text" maxlength="100" placeholder="Article Title"></textarea> <div class="toolbar"> <a onclick="iBold()"><i class='fa fa-bold'></i></a> <a onclick="iUnderline()"><i class='fa fa-underline'></i></a> <a onclick="iItalic()"><i class='fa fa-italic'></i></a> <a onclick="iFontSize()"><i class='fa fa-font'></i></a> <a onclick="iForeColor()"><i class='fa fa-align-left'></i></a> <a onclick="iHorizontalRule()"><i class='fa fa-align-center'></i></a> <a onclick="iUnorderedList()"><i class='fa fa-list-ul'></i></a> <a onclick="iOrderedList()"><i class='fa fa-list-ol'></i></a> <a onclick="iLink()"><i class='fa fa-link'></i></a> <a onclick="iUnlink()"><i class='fa fa-chain-broken'></i></a> <a onclick="iJustLeft()"><i class='fa fa-align-left'></i></a> <a onclick="iJustCenter()"><i class='fa fa-align-center'></i></a> <a onclick="iJustRight()"><i class='fa fa-align-right'></i></a> <a onclick="iImage()"><i class='fa fa-picture-o'></i></a> </div> <!-- Hide(but keep) normal textarea and place in the iFrame replacement for it --> <textarea style="display:none;" name="myTextArea" id="myTextArea" cols="100" rows="14"></textarea> <iframe name="richTextField" id="richTextField"></iframe> <!-- End replacing normal textarea --> <br /> <br /> <button id="article_btn" onclick="saveArticle()">Save Article</button> <br /> <br /> <br /> </form>

I tested this and it works fine:

document.documentElement.innerHTML = '<iframe id="frame"></iframe>'; var frame = document.getElementById('frame').contentWindow.document; frame.open(); frame.write('<html><body>It Works!</body></html>'); frame.close();

You can do this also on already rendered iframe.

And is that also possible to put a dynamic php variable inside the frame write like frame-write('<?php echo $content; ?>');?

And I think you should use frame.close instead of doc.close, but I tried it and also work with php!
