avoid to write html in a textarea

[jonsof]

I am making a user-interface page like the one in that forum. So i don;t want my users be able to write html tags in the textarea!!

Is that practicable?

[ir4z0r]

that's pretty tough to do that, you'd need plenty of javascript

better convert the typed code, for example with htmlspecialchars()

[jonsof]

does this function search throughout the text for such html chars?

[ir4z0r]

example:

$string = "<hr>";
$new = htmlspecialchars($string);
echo $new;
// prints &lt;hr&gt;

so - yes, it replaces each

[jonsof]

example:

$string = "<hr>";
$new = htmlspecialchars($string);
echo $new;
// prints <hr>

🙂

Everything to be treated as a charachter < , h , r, >

[ir4z0r]

yeah, it prints <hr> in a browser, but that's the intention, since it
would normally draw a horizontal line
a quick view in the source code shows that it prints &lt;hr&gt; :p

and this is the intention, isn't it? to disallow execution of html-tags
