Make A Single HTML Page React To Form Input

GOAL:

Use one single HTML page (or SHTML page) to instantly display a different message based upon the website viewer's input to a simple form.

A pop-up or second HTML page is not desired in this matter. The message must appear on the same page as the form, not on a similarly formatted page.


PSEUDO EXAMPLE:

<center>
<select name="color">
<option>Select A Color</option>
<option>Red</option>
<option>Blue</option>
<option>Green</option>
</select>

<span style="color: #FFCC66;">


You selected red.


You selected blue.


You selected green.


Please select a color.

</span>
</center>


COMMENTS:

It is important that the unique message appear in the designated area of the same web page immediately after the website viewer clicks their choice of color. The server environment is a Linux-based hosting service. Your suggestions are requested. Thank you in advance.

Is this task impossible?

Is there even a way of including some PHP code within the HTML page that will accomplish the task?

I think you're going to have to do it with javascript. Look up javascript and Dhtml.

The lack of solutions posted here suggests that you may be correct jestep.


On a similar note about SSI capabilities, can SSIs be used to display a different string of text based upon the date?


PSEUDO CODE


Today is sometime before 2005/07/31.

Today is 2005/07/31 or later.




MODERATORS: While I continue to receive email notifications from all other forums in which I participate, I do not receive notifications from WebProWorld threads in which I participate. The "Notify me when a reply is posted" option is checked on this thread but the notifications are not received - not even in the "deleted" or "spam" folders. How can this matter be resolved?

As you can use PHP it would be better to have a form which posts to its self, then have the PHP redisplay the page inserting the information.

If you use JS only then anyone with JS disabled won't be able to use the page.

A very quick and dirty snippet of PHP/HTML is:

<?php
    $c = 0;
    if(isset($_POST['update'])) {
        switch($_POST['color']) {
        case 1: echo 'Red'; break;
        case 2: echo 'Blue'; break;
        case 3: echo 'Green'; break;
        }
        $c = $_POST['color'];
    }
?>
<form action="#" method="post">
    <select name="color">
        <option value="1" <?php if($c == 1) echo 'selected="selected"'; ?>>Red</option>
        <option value="2" <?php if($c == 2) echo 'selected="selected"'; ?>>Blue</option>
        <option value="3" <?php if($c == 3) echo 'selected="selected"'; ?>>Green</option>
    </select>
    <input type="submit" name="update">
</form>

If you then add a JS onchange handler to <select> then as the user changes the selection the form will auto submit, if the user doesn't have JS then they will have to click the submit button.

I would use PHP.

If like me you are using a block list you'll have to explicitly allow emails from this board through as they seem to have got their servers listed as a spam source.
