checkbox problem

irishgirl2004

Hi,
I have a number of checkboxes on a form, and when a user submits the form i do some validation, and if all the correct items are not selected, then the page should display again, containing the information they entered. For some reason, the checkboxes are not displaying as checked when the for is displayed after the validation. Here's the code

<input name="dem" type="checkbox" id="dem" value="checkbox" <? print $_POST['dem']; ?>>

[code=php]


any ideas?

thanks

<input name="dem" type="checkbox" id="dem" value="checkbox" <?php if (!empty($_POST['dem'])) echo 'checked="checked"'; ?>>

Ok I have seen and understand how to make a checkbox sticky from a "Post" point of view. My question is. I use a query from a database table to fill in all the info someone previously updated. I have figured out how to fil text areas, text boxes and even drop down's. But for the life of me I can not figure out the checkboxes.

I use a session varible to pull a query based on $_Session['username'] the query works perfectly.

<?php

session_start();
include_once 'header.inc';
include_once 'check_status.inc';
include_once 'db.php';

$username = $_SESSION['username'];
$userlevel = $_SESSION['userlevel'];
$membertype = $_SESSION['membertype'];

$profilelist=mysql_query(
        "SELECT * FROM profileone WHERE usernm='$_SESSION[username]'");

while ($prof = mysql_fetch_array($profilelist)) {
$profileid = $prof['profileid'];
$userlvl = $prof['userlvl'];
$usernm = $prof['usernm'];
$birthmonth = $prof['birthmonth'];
$birthday = $prof['birthday'];
$birthyear = $prof['birthyear'];
$height = $prof['height'];
$weight = $prof['weight'];
$bodymark = $prof['bodymark'];
}

//truncated: as this is a huge page

?>

Then I go in and out of PHP to fill in info to the various fields, so that the users current information is pulled from the database and automaticaly entered into each field so they only have to change the things they want to.

Please enter your birthday:</font></b></td>
            <td width="74%" valign="bottom"><b>
            <select size="1" name="birthmonth">
            <option value="<?php echo $birthmonth ?>"selected><?php echo $birthmonth ?></option>
            <option value="January">January</option>
                <option value="February">February</option>
                <option value="March">March</option>
                <option value="April">April</option>
                <option value="May">May</option>
                <option value="June">June</option>
                <option value="July">July</option>
                <option value="August">August</option>
                <option value="September">September</option>
                <option value="October">October</option>
                <option value="November">November</option>
                <option value="December">December</option>
                </select><font size="2">

This method is simple and works well for me as I develop this small site.

MY QUESTION: How do I jump into PHP and make the checkboxes work?
One note though... When the form is processed after submission I store all of the checkboxes (array) into one field in the database using the "Implode" function...

/* 
From the processing code, not part of this from (just for reference)
$String1 = implode(", ", $_POST['bodymark']);
*/

How would I make the following sticky (if that's possible after storing them with implode)?

<input type="checkbox" name="bodymark[]" value="Ear Piercings">Ear
                Piercing(s)<br>
<input type="checkbox" name="bodymark[]" value="Nose Piercings">Nose 
                Piercing(s)<br>
<input type="checkbox" name="bodymark[]" value="Nipple Piercings">Nipple 
                Piercing(s)
<input type="checkbox" name="bodymark[]" value="Other   Piercings">Other            

                Piercing(s)<br>  

<input type="checkbox" name="bodymark[]" value="Tattoos">Tattoos<br>
