Need Help displaying Form Input

TextArea

[Gian04]

I have a textarea in a form that accept input from users. Those who are requesting banner exchange will use the same form.

I have an admin page where I can view submitted inputs from users. My problem is user can input things like this:

<a href="http://www.example.com"><img src="http://www.example.com/banner.gif"></a>

When I view it on my admin page, it display the actual banner, and NOT the code as shown above.

How can I make it display just the code and not the actual banner?

[edit reason] use example.com instead [/edit]

You are going to need to change the string into its entities before echoing to the browser. Use htmlentities [php.net] for this.

I dont know how to do it, can you give a little example, given the HTML Code above. I mean I know HTML entities but I dont know how to implement in this case (given that I cant predict the user input). Thanks

$html = '<a href="http://www.example.com"><img src="http://www.example.com/banner.gif"></a>';
echo $html; #without entities
echo htmlentities($html); #with entities

>> given that I cant predict the user input

The user input is wherever you are storing the code. I'm assuming you are storing the code somewhere?

Thank you very much eelixduppy it works.

My next problem is, even if there are 3 paragraphs (because the user press ENTER) it displays in a continuous manner (1 paragraph)

This is overcome by using nl2br [php.net] on the string. So something like this:

echo htmlentities(nl2br($html));

Thank you very much eelixduppy it works.

But it should be
echo nl2br(htmlentities($html));

because
echo htmlentities(nl2br($html));

will just display the '<BR>'

I thought that is what you wanted, but I guess not ;)

glad you got it working!
