How redisplay html form after submission

[AdRock]

I would like to redisplay my form with the updated details in the form.  At the moment after the form has been submitted it is no longer visible when the page refreshes.

Here is my code

[code]<?
$fund = file_get_contents($myFile);

if (!isset($_POST['fund'])) {

?>
<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
    <fieldset>
    <legend><b>Current Fund Amount</b></legend>
    <p style="margin-left:10px;">The current fund is:<br>
    <input type="text" title="Please enter the new current fund amount" name="fund" size="30" value="<? echo $fund ?>">
    <input type="submit" value="Submit" class="submit-button">
    </fieldset>
</form>
<?}

else {
    $fh = fopen($myFile, 'w') or die("can't open file");
    $stringData = $name;
    fwrite($fh, $stringData);
    fclose($fh);
    echo $thankyou_message."  Click <a class=\"two\" href=\"javascript:history.go(-1)\">here</a> to go back";
}
?>[/code]
How do i change it so when the form has got a new value saved the new value is displayed in the same form?

After the }else{ statement, assign $fund=$_REQUEST['fund'];

Then copy the 8 lines that print the form out and put them immediately following that.

So, [code]<?}

else {
    $fh = fopen($myFile, 'w') or die("can't open file");
    $stringData = $name;
    fwrite($fh, $stringData);
    fclose($fh);
    echo $thankyou_message."  Click <a class=\"two\" href=\"javascript:history.go(-1)\">here</a> to go back";
}
?>[/code]

becomes
[code]<?}

else {
    $fund=$_REQUEST['fund'];
?>

<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
    <fieldset>
    <legend><b>Current Fund Amount</b></legend>
    <p style="margin-left:10px;">The current fund is:<br>
    <input type="text" title="Please enter the new current fund amount" name="fund" size="30" value="<? echo $fund; ?>">
    <input type="submit" value="Submit" class="submit-button">
    </fieldset>
</form>


<?
    $fh = fopen($myFile, 'w') or die("can't open file");
    $stringData = $name;
    fwrite($fh, $stringData);
    fclose($fh);
    echo $thankyou_message."  Click <a class=\"two\" href=\"javascript:history.go(-1)\">here</a> to go back";
}
?>[/code]

Thanks blear, that worked but i have come across another problem
That form is only part of my admin page and by doing that I can't use any of the other page links.

I did think about using iframes to do just that update but i don't know how to do it

here is the code for the whole page (without the changes)

[code]<?
$myFile = "../includes/thermometer/testFile.txt";
$name = $_POST['fund']; // vars from form
$fund = file_get_contents($myFile);
$empty_fields_message = "<p>Please go back and complete all the fields in the form.</p>Click <a class=\"two\" href=\"javascript:history.go(-1)\">here</a> to go back";
$thankyou_message = "<p>Thankyou. Current fund amount has been updated.</p>";
?>

any suggestions how how i can update the fund and still refresh the whole page either using iframes or a better way if possible?

You need to write <?php echo $_SERVER['PHP_SELF'];?> you are missing the echo.

that didn't make any difference
