When I use the code provided below everything works fine unless there is an apostrophe or other html special characters in the SESSION I am trying to pass in the value. I have tried both htmlspecialchars() and htmlentities() with no success. please help. thanks, James

<?php
<form action='ashlyBlogBig2.php' method='POST'> 
    <input type='hidden' name='title'   value='{$_SESSION['title']}'/>
    <input type='hidden' name='time' value='{$_SESSION['time']}'/>
    <input type='hidden' name='blog' value='{$_SESSION['blog']}'/>
    <input type='submit' name='to you' class='productButtons' value='Read On. . . .'>
</form> ";
?>

Use ENT_QUOTES as the second param to htmlentities(), to be certain that both single and double quotes are encoded inside the variable.

echo  "<input type='hidden' name='blog' value='" . htmlentities($_SESSION['blog'], ENT_QUOTES) . "'/>"

Since htmlentities() is a function call, it cannot be interpolated inside a double-quoted string the way a variable, array element, or object property can. You must close the currently open string and concatenate in the return of a function call.

The ENT_QUOTES flag to htmlentities() encodes both single and double quotes, making a string suitable for use inside an HTML attribute (which is already quoted).
