One More Question On CheckBoxes & PHP

cpd259

Is there a way to have PHP uncheck a checkbox?

I would like to code something similar to this:

if (isset($_POST["Var_Box1"])) {
Var_Box1.checked=""
}

I am sure this is wrong but can someone provide me with an answer?

Thanks..Charlie

I don't understand why you would want to make it not checked.

Unless you have a checked attribute in the input tag, it won't be checked when the page loads.

And php is a server side script so it can't change the page once its been sent.

We have a situation where a production version of a label will require that a specific counter will only be initialized to 1 when a new set of parts is encountered. In this way, to make this as user friendly as possible, after the user has checked this box the first time, I would like to uncheck it so that the counter isn't initialized back to one until the user has a new group of parts. The user will check this box again, I will reset the counter for the next group so the counter can start over again, keep incrementing the counter until the user checks the box again. This cycle will continue until the user doesn't need any more labels. The use of this is for a customer specific label which we have no control over. This is what a customer wants for their inventory system. Can this be done? There is a lot of data already on the screen which I don't want to use the refresh because the user would have to key all of the same data back in. I am trying to keep this system as simple as possible.

Hmm. I think you might be looking for a javascript function.

Merely checking a box is not going to send anything to the php server.

This requires that everything is HTML and PHP to begin with.
I guess something can be done with the help of SESSION and a form, but it would be helpful to perhaps see some code or screenshots etc to get a bit better understanding of what you try to accomplish.

To controll if a checkbox is checked or not
This will be checked:

<input type="checkbox" name="Bike" checked="checked">

and this unchecked

<input type="checkbox" name="Bike">

After the form is submitted you store all the typed in info in $SESSION, need to use session_start in both scripts, so when the first script is recalled you can do a

if (isset($_SESSION['some_name']))
{
  #print out all the info you want to keep here
}

In the script that the form calls, you use session_register('variable_name') and then

$_SESSION['variable_name']==$_REQUEST['some_field'];
