In the example you have given, which equates to a Get, the variables will

Hi Ron and everyone else,

Thanks for your response. Let me expand a bit on my requirement. I have
a dynamically generated form where I am now trying something similiar.
To wit:

<input name='inp[0]' type='checkbox' value='first value'>
<input name='inp[1]' type='checkbox' value='second value'>
<input name='inp[2]' type='checkbox' value='third value'>
.
.
etc

Basically, I present a user with a dynamically generated checklist and
I am trying to see all the values that he has checked.


once this is received by your PHP script the values may be retrieved :

$myArray = $_REQUEST('ip'); // note no subscripts required

$myArray['0'] will contain 'first value', $myArray['1'] the second value,
and so on



Doing as you have suggested, count($myArray) gives the correct number
of values ticked.

But only $myArray['0'] is set!
$myArray['1'], $myArray['2'] , ..., etc are not set!

Not to flame or anything, I AM quite surprised by how arcane processing
a checklist in php is turning out to be. :-)


Thanks again!

Girish,

First of all, it should be $myArray[0], not $myArray['0']. It has a numeric index. And the fact count($myArray) has the correct value indicates the values are correct.

Also, the way you have it coded, if the 'second value' checkbox is not checked, myValue[1] will not be set and you'll get a notice if you try to use it. Unless you absolutely have to have the indexes like that, a better way is to use:

<input name='inp[]' type='checkbox' value='first value'>
<input name='inp[]' type='checkbox' value='second value'>
<input name='inp[]' type='checkbox' value='third value'>

Now inp[0] will contain the value from the first checked box, imp[1] will contain the value from the second checked box, etc.

Also, I agree with Anthony but for different reasons. I suggest you use POST instead of GET. Not because of the array (it should work in either), but because it can get to be quite a long URL if the user checks several boxes.
