Converting from ASP to PHP help.

[TapeGun007]

I have a database that contains several "Groups" that people belong to.  My web page reads the database and spits out the groups onto the page.  The form allows you to select which groups you want and passes this information onto the next page.

(see picture)

 

The form you see in the picture simply uses the input tag Checkbox.  The checkbox is named in sequential order, so...

Group1 = Choir

Group2 = Chorale

Group3 = Directors

..etc

 

In classic ASP, the next page would read how many groups were selected with this code:

Dim a
For a = 1 to Request.Form("GroupName").Count
Response.Write(Request.Form("GroupName")(a) & " was selected<BR>")
Next

 

How can I do this same thing in php?

Instead of naming the checkboxes in sequential order, they should be named as an array

<input type="checkbox" name="groups[]" value="Choir" />
<input type="checkbox" name="groups[]" value="Chorale" />

 

Then in the processing page you would just do this

if(isset($_POST['groups'])) //Only run if checkboxes were selected
{
    foreach($_POST['groups'] as $groupName)
    {
        echo "{$groupName} was selected<BR>\n";
    }
}

Ah yes, that works perfectly.  I was getting closer and closer to the answer.  I knew there was a foreach command, just wasn't sure how.  Plus, I didn't know you could simply pass the array like that.

 

That's great!

 

Thank you.

Yeah, I'm pretty sure that works for ASP as well, but it's been years since I used it. The one thing to be aware of with that is that referencing those fields in JavaScript is somewhat counter-intuitive. They are still an array, but not how you might think.

 

Example:

var checkboxGroup = document.forms['formname'].elements['groups[]'];

Note the use of "[]" in the referenced name.
