Re: Need some advice concerning forms (multi select pulldown) and arrays

Ok, I can't get this right... Have the following code: <? $choices = array(1 => 'dog', 2 => 'cat', 3 => 'mouse', 4 => 'frog'); if (is_array($_REQUEST['animals'])) { // get the number of selectcases echo "get the number of selectcases: " . count($animals) .. "<br>"; // get the number of provided selects from select with name "2" echo "get the number of provided selects from select with name \"2\": " . count($animals[2]) . "<br>"; // test to print some data

      	echo $animals[2][0]. "<br>";
      	echo $animals[2][1]. "<br>";
      	echo $animals[2][2]. "<br>";
      	echo $animals[2][3]. "<br>";

} ?> <form method="post" action="<?= $_SERVER['PHP_SELF'] ?>"> <select multiple name="animals[2]"> <option value='1'>dog</option>

    	<option value='2'>cat</option>
    	<option value='3'>mouse</option>
    	<option value='4'>frog</option>

</select>

    <select multiple name="animals[4]">

<option value='1'>dog</option> <option value='2'>cat</option> <option value='3'>mouse</option> <option value='4'>frog</option>

    </select>

<input type="submit"></form> Why does it not work? // get the number of selectcases echo "get the number of selectcases: " . count($animals) .. "<br>"; This works great // get the number of provided selects from select with name "2" echo "get the number of provided selects from select with name \"2\": " . count($animals[2]) . "<br>"; But this doesn't... Thankful for any help, /Victor On Sunday, May 26, 2002, at 05:35 PM, John Holmes wrote:

You can supply an "whateverID" for the select if you want to. <select name="select[]"> <option ... </select> <select name="select[]"> <option ... </select> etc... That will give you an array $select[] on the processing page. If the selects are multi-selects, you'll have a multidimensional array. The first chosen element in the first select box can be referenced like this $select[0][0] You can get a count of how many select boxes there are by doing count($select); You can get a count of how many elements were selected within a select you can do this: count($select[x]); Where x is the number of the select box you want to know about. Confusing, eh? ---John Holmes...

Just give each select its own name.

Can't do that, don't know from time to time how many there'll be....

And

I've to have some case which iterates on the following page...

Or name them all the same followed by an [] and you'll end up with a multi-dimensional array if things

go

right...

Sounds better - but I've a lot of items and I'ld like to know which of the arrays that go to which item... Can I just write …name=array[whateverid] and then in some way reveal the whateverid's? Sincerely Victor
