How to make an array

cheeks2k

... well, not exactly. I used to have code like this:

<input type="checkbox" name="defender[]" id="def1" value="Cafu" />Cafu (AC Milan)<br />

So I could check various boxes, make an array called 'defender' and pass it to another page. Cool.

Except, I put a javascript validation on the form and it wouldn't work with the [] so I had to remove them:

<input type="checkbox" name="defender" id="def1" value="Cafu" />Cafu (AC Milan)<br />

That works fine for the validation, but now when I try to pass the values to the next page, only the last value in the 'array' appears.

How can I turn the values into an array without using [] in the name attribute of the checkbox?

If anyone can help I'll provide full code for you to look at.

As is often the case, that's led me on to a new problem...

This is my javascript code:

function validate()
{
var totalgol = 0;
    var maxgol = document.forms[0].elements['goalkeeper[]'].length;
    for (var idx = 0; idx < maxgol; idx++)
        {
        if (eval("document.forms[0].elements['goalkeeper[" + idx + "]'].checked") == true)
            {
            totalgol += 1;
            }
        }
    if (totalgol != 1)
        {
        alert ("Please choose a goalkeeper");
        return false;
        }
return true;
}

And this is my form:

<form action="new_pick2.php" name="pickateam" method="post" onsubmit="return validate();">
<input type="checkbox" name="goalkeeper[]" id="gol1" onClick="countGol(this)" value="Dida" />Dida (AC Milan)<br />
<input type="checkbox" name="goalkeeper[]" id="gol2" onClick="countGol(this)" value="Julio Cesar" />Julio Cesar (Flamengo)
</form>

But when I sumbit the form I get a Javascript error:

Error: document.forms[0].elements['goalkeeper[0]'] has no properties

And the value is passed into the next page as the word 'Array'.

Sorry, I know this is more Javascript than PHP, but it's combining the two that's killing me.

Don't use javascript to validate things.

Fact: Over 10% of web users have client-side scripting switched off.

Let's say I'm doing this for myself, just to see if I can.

So, how do you recommend we do validation then??

Thanks
