PHP.NET - htmlspecialchars

PHP.NET - htmlentities

This is not the right html code for a textarea. What you should do is this:

PHP Code:

<textarea name="descrizione_problema" id="id_class_descrizione_problema" class="form-control" rows="12" maxlength="65535">
<?= $val;?>
</textarea> 


Use the esc() helper function:

PHP Code:

<input type="text" name="myfield" value="<?= esc($string); ?>" />

@includebeer, that's a CI 4 method. You can use html_escape(value), or form_prep().

Yeah, but people should really develop new projects with CI4!
