variable passing

[scuba]

Thanks to those who helped out before. But I've created another problem now. How does a fella pass a multidimensional array to the next script?

I have: $info[$count][4] = $Username;

which later is called in a form like:

<td width=30% bgcolor='F1F1F1' align=left><font face=verdana size=1 color=black>"); echo($info[$count][4]);echo("</td>

this has a check box at the beginning of each row. depending on whether it is checked or not and person will be disabled or enabled.

so now in my other script I want to say:

for ($count=0; $count < $max; $count++)
{

if ($info[$count][5] == 'on')
{
$sql = mysql_query("UPDATE Subscriber SET Disabled = '$Disabled' WHERE Username = $info[$count][4]");

but I don't think the variable is passed right. any help?

Thanks,
Steve

I don't think that HTTP will pass multidimensional arrays. I believe that you are stuck with a single dimension just like you are stuck being unable to use associative arrays. It's just something that wasn't thought of when things were put together and so it can't be done.

I may be wrong but I've never been able to get it to work.

hmmm....nasty, what if I was able to do something like this:

echo("<input type='hidden' name='max' value='$max'>");for ($count=0; $count < $max; $count++)
{
echo("<input type='hidden' name='");echo(Fname[$count]);echo("' value='");echo($info[$count][0]);echo("'");
echo("<input type='hidden' name='");echo(Lname[$count]);echo("' value='");echo($info[$count][1]);echo("'");
echo("<input type='hidden' name='");echo(Email[$count]);echo("' value='");echo($info[$count][2]);echo("'");
echo("<input type='hidden' name='");echo(Country[$count]);echo("' value='");echo($info[$count][3]);echo("'");
echo("<input type='hidden' name='");echo(Username[$count]);echo("' value='");echo($info[$count][4]);echo("'");
echo("<input type='hidden' name='");echo(Disabled[$count]);echo("' value='");echo($info[$count][5]);echo("'");
}
echo("<INPUT TYPE='SUBMIT' name='submit' value='Submit'></td>
</tr>

technically that should pass the variable for each one, then I might be able to use them in the other script. Do you think this may be plausible?

That should work, but you won't have your nice clean array, you'll have a bunch of nasty variables that you'll need to clean up.

I was thinking that you could do something like this:

echo("<input type='hidden' name='max' value='$max'>");for ($count=0; $count < $max; $count++)
{
echo("<input type='hidden' name='");
echo("info_$count_0");
echo("' value='");
echo($info[$count][0]);
echo("'");

That would give you a bunch of variables called $info_1_0, $info_1_1, etc.. then you coule write a simple little function to rebuild your array:

function rebuild_array($post_vars) {
&nbsp;$new_array = array();

&nbsp;for (reset($post_vars); $key = key($post_vars); next($post_vars)) {
&nbsp;&nbsp;list($name, $count, $extra) = explode("_", $key);

&nbsp;&nbsp;if ($name = "info") {
&nbsp;&nbsp;&nbsp;$new_array[$count][$extra] = $post_vars[$key];
&nbsp;&nbsp;&nbsp;}
&nbsp;&nbsp;}

&nbsp;return $new_array;
&nbsp}

you love those echo's don't you ?? 🙂)

You know that you can combine the data for a echo ?

echo("<input type='hidden' name='");echo(Fname[$count]);echo("' value='");echo($info[$count][0]);echo("'");

would be:

echo("<input type='hidden' name='.Fname[$count]."' value='".$info[$count][0]."'");

IMHO it looks a bit clearer 🙂

But to your problem:
You can pass any vars via a form (and ofcourse arrays) I've done it, and i think the problem lies within your html, since your first post looks a bit strange, you could send me your php/html part again, and i have a look over it. But what you intend to do works (at least for me)...

Not true 🙂

If you have a field:
<input type="text" name="myfield[0][1]">

when the script receiving this data gets it, you can just say

echo $myfield[0][1];

and see your result.
If you try to use javascript to do something with this field, you'll need to do some funky stuff.
