POST problem

[ayj]

This is an embarrasing question because it is way too simple but I have looked in the php manual, googled and searched, even read my HTML textbook and got nowhere 🙁.

Using a POST statement with a checkbox eg

<form action='debugformdot.php' method='post'>
 <p><input type='checkbox' name='test.gif' id='test.gif' />test.gif</p>

The POST address in the receiving script becomes $POST['test_gif'], with value "on" ie in the file-name "." changes to "". I have tried different enctypes in the form statement to no avail. I made a workaround that was fine involving converting the "." to "/" and then back again later but decided today it would be better to learn by resolving the fundamental problem instead.

I am using that checkbox to pass a pre-selected file-name via it's key. Maybe that is the mistake and I need to pass the file name as the value but that approach doesn't work as well on the other end.

Any suggestions as to what I should be doing.

The reason for that is that periods (dots) are not permitted in PHP variable names, hence are replaced by underscores.

Variables from outside PHP is the relevant entry in the PHP Manual, under the section "Dots in incoming variable names".

Thanks Laserlight

It's funny how one can know something from one angle but not get it from another. Glad I asked because now I understand.
