Disable checkbox

[sheldonlg@gmail.com]

I have a checkbox that I set by php code to be either "checked" or "".
I want to disable the ability of the user to check or uncheck it. I
tried "readonly", but that didn't work. Any suggestions?

I think it is disabled="true" that you want to use. That should work, I
think.

HTML style:
<input type="checkbox" name="foo" disabled>

XHTML style:
<input type="checkbox" name="foo" disabled="disab led"/>

The "disabled" worked. What is that trailing slash for?

XHTML compliance. In XHTML, all tags must have matching closing tags.
Some tags are "self-closing" however (like <input>) so instead of a
</input> you just leave a trailing / to close it.

Disabled and readonly are different things - IIRC the values of readonly
elements are submitted while the values of disabled elements are not. So
the OP could run into problems in the case of:

<input type="checkbox" name="foo" value="1" checked disabled>

In this case readonly is definitely the correct attribute. Internet
Explorer seems not to support readonly, though, which is a bug.

Anyway as this is not a PHP topic there might more detailed information
to be found in an HTML group.

Re: Disable checkbox

In my case it is "disabled". The reason is that I want to show which
uploads have been done as indicated by the presence of the file on the
server. I dynamically put in "disabled" or leave it blank. If it is
disabled, I set it as checked. I do this by checking for the presence
of the files on the server and setting session variables if they are
there. In other words, the check box is not a "choice". Rather, it is
an indicator of completion.

When the user does the submit for the entire transaction, I first check
to see if all the required uploads are present (not all are required),
and then process the information. (All that is done is PHP). If they
are not all there, I present the user with information about the what
is missing.

When he uploads the missing file, the checkbox is set as checked and
disabled.
