populating rad chk inputs with posted data

[horseatingweeds]

How do you populate input elements other than text inputs with posted data?

[Dragosh]

for textarea i do like that :
<textarea><?php echo 'something here'?></textarea>
or you could do that with ajax. how to do that look on w3schools.com

I'm getting closer. This code works for all of the check elements except for the first one: 'New Puppies'

I get an error for the $pup variable not existing in the form. Anyone see what I'm doing wrong?

<fieldset>
<legend>What do Your Activities Provide?</legend>
<input type='checkbox' name='chkActivities[]' value='New Puppies'
<?php popActivities($pup);?> /><label>Doberman Puppies</label><br />
<input type='checkbox' name='chkActivities[]' value='Adult Dobermans'
<?php popActivities($adult);?> /><label>Adult Dobermans</label><br />
<input type='checkbox' name='chkActivities[]' value='Trained Dobermans'
<?php popActivities($trained);?> /><label>Trained Dobermans</label><br />
<input type='checkbox' name='chkActivities[]' value='Stud Service'
<?php popActivities($stud);?> /><label>Stud Service</label><br />
<input type='checkbox' name='chkActivities[]' value='Doberman Rescue'
<?php popActivities($rescue);?> /><label>Doberman Rescue</label><br />
</fieldset>

function popActivities($a)
{
if (isset($_POST['chkActivities']))
{
GLOBAL $pup;
$pup = '';
GLOBAL $adult;
$adult = '';
GLOBAL $trained;
$trained = '';
GLOBAL $stud;
$stud = '';
GLOBAL $rescue;
$rescue = '';
foreach($_POST['chkActivities'] AS $activity)
{
if ($activity == 'New Puppies')
{$pup = "checked='checked'";}
if ($activity == 'Adult Dobermans')
{$adult = "checked='checked'";}
if ($activity == 'Trained Dobermans')
{$trained = "checked='checked'";}
if ($activity == 'Stud Service')
{$stud = "checked='checked'";}
if ($activity == 'Doberman Rescue')
{$rescue = "checked='checked'";}
}
}
echo $a;
}

I couldn't get the point why you have declared that many global variables. Unless you have a different purpose for them, the following function should do it all:

<?php
function popActivities($a)
{
if (isset($_POST['chkActivities']))
{
foreach($_POST['chkActivities'] AS $activity)
{
if ($activity == 'New Puppies' ¦¦ $activity == 'Adult Dobermans' ¦¦ $activity == 'Trained Dobermans' ¦¦ $activity == 'Stud Service' ¦¦ $activity == 'Doberman Rescue')
{
$chk_status = "checked='checked'";
}
}
}
echo $chk_status;
}
?>

You need to change those "¦¦" to the appropriate vertical ones.

Hi Habtom,

Won't your function create a checked='checked' for all check elements if even one check element is checked?

No. You are calling the function at all the times. Just to ensure its 'freshness' add the following just after the function:

function popActivities($a)
{

$chk_status = '';

But wait, let me have a second look at it.
