The variable contains a string, not a boolean value. true is a constant that
evaluates to either True or False (numerically -1 or 0).

So you need to a) cast the variable to a boolean using cbool() or b) compare
the variable to a string, using "true".

However, this is not the optimal method. If the checkbox is not checked, it
will have no value. So simply check the variable's length:
if len(request.form("mychk")) > 0 then
'it was checked

HTH,

If the checkbox is checked then it has a value, if it's not then there's
nothing
if Request.Form("mychk")="" then
'not checked
else
'checked
end if

or you can specify
<input type=checkbox name=mychk value='BOB'>

if Request.Form("mychk")="BOB" then
'it was checked
end if

You can also use the same name for multiple checkboxes (like you do for
radio buttons)
<input type=checkbox name=mychk value='BOB'>BOB
<input type=checkbox name=mychk value='FRED'>FRED

Response.write Request.Form("mychk") would display BOB, FRED (assuming both
checked)

Hi all,

I am wondering what would be the best way to handle checkboxes. I am
making a site that will display several items in a 20-items-per-page
format and each item will have a checkbox next to it for the user to
select them. Now, what I need to do is to record the items selected by
the user when clicking the “Next button” into a MySQL table. Should I
name all the checkboxes the same, using the item IDs as values and then
use an array to see which ones where selected or maybe another thing?

Thanks in advanced,

Cesar Aracena

Okay, I've only been doing php/mysql for a few months and I admit to
being a little stumped on this one.

I have a form which posts updates to a mysql table. I'd like to use
checkboxes to show and update boolean type values. In Access it's very
simple to create a field of type Yes/No, bind a form to the table, and
bind a checkbox object to the Yes/No field. I am unable to find generic
examples of this in php/mysql.

1. What field type should I use in a mysql table?
2. When the php<html><form> loads the data from the selected record,
what is the generic syntax for initializing the check box?

MySQL has a BOOL type but it's just a synonym for TINYINT(1).
Another possibility would be ENUM.

Here's one way:

// Set the variable $foo from the database or from form data.
$checked = $foo ? "checked" : "";
echo "<input type=\"checkbox\" name=\"foo\" $checked>";

Or later if you're outside PHP:

<input type="checkbox" name="foo" <?php echo $checked?>>

Or you could omit the $checked variable:

<input type="checkbox" name="foo" <?php echo $foo ? "checked" : ""?>>

There are several ways to do this; the important thing is to print
the "checked" attribute if the boolean variable is on/true.

Although, in the newer implementations of HTML, that would be

$checked = $foo ? 'checked="true"' : '';

Shouldn't that be 'checked="checked"'? That's what the XHTML 1.0
DTD appears to require, and using "true" causes XHTML 1.0 and 1.1
documents to fail validation at validator.w3.org.

Got it working...thanks. The exact syntax for the checked argument is
where I was getting stumped.

Meanwhile, I came up with another fairly trivial question. I'll post it
under the heading "Textarea Formatting".

:confused;

I have developed a roster sign-up list on my website. I want visitors to be
able to go in, check off their names, and have that infomation remain on the
site for everyone to see. As each players updates the site, I want the
checkboxes to remain clicked. Right now, the checkboxes turn blank on refresh.
Is there a way I can add a checkbox that will "stay checked" once it's been
clicked? Maybe using Javascript?

Thanks
