HTML表单名称=会话

Question

I pass an individual filename as a session to my HTML form name. My first code prints a list of the files in my directory "diary", and I am trying to print the contents of the chosen file in a new page readpage.html But to my horror, since I am passing the session $_SESSION['filename'] as a variable, all my buttons direct me to the last file that my session variable has been assigned to.

What can I do so that each button passes the a different filename? I have found it impossible to pass a php variable as my form input name, since $variable = $_POST[PHP VARIABLE] doesn't work..

note) I'm trying to achieve this by using PHP only (no javascript, mysql tables etc) Thank you

$folder = "diary";
    $files = scandir($folder);
    $fName = "diary/$file";
    ?><form method="POST" action="readPage.html"><?
    foreach ($files as $file)
    {
        if($file != "." && $file != "..")
        {
            $_SESSION["file"] = $file;
            $data = file_get_contents("diary/$file");
            $info = explode("\t",$data);
            ?>
                <input type="radio" name = <?=$_SESSION["file"] ?> >
                <?=$info[0]?> <input type="submit" value = "Go"  ><br>
            <?
        }
    }
    ?></form><?

Receving file readpage.html

    echo $_SESSION["file"];
    $fOpen = "diary/".$_SESSION["file"];
    $fData = file_get_contents($fOpen);

You opened up a php segment here with

< ?, when it should be < ?php

this

? > < form method="POST" action="readPage.html" > < ?php

not this

? > < form method="POST" action="readPage.html" > < ?
