Simple Array question

[Ryan A]

Hi,
If i am posting something like this from a form:
<input type=checkbox name='id[sh1]' value=3>
<input type=checkbox name='id[sh2]' value=4>

How do i get the value of id[]?
eg:
I dont want the "sh1" and "sh2", i just want the "3" and "4"

The reason i dont wan the sh1 and sh2 is those are dynamic and will be
changing, I just need the values (in this case 3 and 4) to do some
comparasion and assignment operations

Kindly reply.

Thank,
-Ryan

I think what you want is:

<input type="checkbox" name="id[]" value="3">
<input type="checkbox" name="id[]" value="4">

Then on your next page, you can just do:

foreach($_POST['id'] AS $row)
echo $row;

Or whatever, and that way you only get what you need.

Normally array values start at 0 (zero), but let's say sh1=1 and sh2=2. then
you could echo the values out like this: echo "ID 1: $id[1]<br>ID 2:
$id[2]<br>";

Hi,
Thanks for replying.
I tried that and have 2 numbers like so:

<input name="id[sh123]" type="hidden" value="32">
<input name="id[sh1sd]" type="hidden" value="563">

and tried to echo it like so:
<?php
$id=$_POST['id'];
foreach($_POST['id'] AS $row)
echo $row;
?>
Echo of one is <?php echo $row[0]; ?> and echo of two is:<b> <?php echo
$row[1]; ?></b><br><br>
Echo of one is <?php echo $id[0]; ?> and echo of two is:<b> <?php echo
$id[1]; ?></b>

the output i got was:
******************
32563Echo of one is 5 and echo of two is: 6

Echo of one is and echo of two is:
*****************


AS you can see its totally wrong.Any other ideas?

cheers,

I GOT IT!!!!

this is where the data was coming from:
<input name="id[sh123]" type="hidden" id="id[sh123]" value="32">
<input name="id[sh1sd]" type="hidden" id="id[sh1sd]" value="563">

and this is where i take the values and dump it into an array/variables that
i can call when and where i please:

<?php
$nn=0;
foreach($id as $nname => $pppno)
{$asdf[$nn]=$pppno;
$nn++; }
?>
<br><br><?php echo $asdf[0]; ?><br>
<?php echo $asdf[1]; ?>


I just took out some of the breaks so it will take less space but you get
the idea.

Thank you to everyone who tried to help, but maybe i didnt explain the
problem well enough that you didnt get the answer or just didnt want to :-D

Cheers,
-Ryan

No... you're getting exactly what you ask for. You rely on this list to
much.

1. You have no braces so your foreach() is taking the next line as the
part that should be executed on each loop.

2. Loop 1 sets $row = 32. Then it's displayed

3. Loop 2 sets $row = 563. Then it's displayed

4. So now $row = 563. When you display $row[0], you're asking for the
first character of $row, so 5 is displayed. $row[1] displays 6.

5. Now you go back to $id. Well, $id = array('sh123' => 32, 'sh1sd' =>
563). So, when you try to display $id[0] and $id[1], there are no
cooresponding values, so nothing is displayed.

Now, how do you do this correctly?

foreach($_POST['id'] as $key => $value)
{ echo "The random key is $key, the value is $value.<br />"; }

which will give you:

The random key is sh123, the value is 32.
The random key is sh1sd, the value is 563.

What do you want, besides that?

Seriously?

You could just replace the above with:

$asdf = array_values($_POST['id']);

I think you need to be cut off from the list for a while. Trial by fire,
I say!!

Hey John,
I guess you are right, I do rely on this list quite a bit but am not the
only one.
Am learning by my mistakes though and finding solutions...they may not be
the best solutions but they still work, everyone has to learn.
Thanks for replying to the question though. And i didnt know about the
"array_values" thing....see? the more you reply to me the more i learn :-D
Cheers,
-Ryan
