[Resolved] add elements to an array

juschillinnow

Step 1

Step 2
<form>
<input type="text" name="check[different]">
</form>

These represent two different pages and I'm trying to pass the array check through several different pages, but it's not working very well.

It seems like, instead of check[different] being added to the array ( check[check] ) it seems to overwrite it and make it non-existent.

I looked at array_push, but wasn't sure how to use it here.

Any suggestions?

I want to end up with at the end, with all my values in $check

If RG=on, then check[] should work. Otherwise, keep in a session, maybe: $_SESSION['check'][] ??

<?php
$this=array();
// basic idea here...
while ($x<3) {
   $this[]=$x;
   $x++;
}

print_r($this);

?>

Or, on the second page, you could pass the variable from the first page as a hidden value.

Step 1
<form>
<input type="text" name="check[check]">
</form>

Step 2
<form>
<input type="hidden" name="check[check]" value="<?= $check[check] ?>">
<input type="text" name="check[different]">
</form>

HTH

I don't think it's a rg problem. I have done some testing to come to that conclusion.

and the 'pass as a hidden value' defeats what I'm trying to accomplish.

I have like 100 values to pass through several pages, and so I'm trying to do it all in one array.

Any more ideas on adding to the array?

You want to create an ever growing array across several pages.

Only four ways I can think of:

Hidden input values (already suggested)
Sessions (already suggested)
Cookies (unreliable)
Query string (unsecure)

Pick your poison...

juschillinnow

CHEERS!

juschillinnow

ok, If I use the HIDDEN method.....

How can I pass the array so I only have to define it once like:

Then on the receiving page I only have to pass $info instead of definig each hidden field again; AND specify more variables for the info array?

so on the next page it would look like:

instead of:

where I'm doing my work all over again?

Make sense?

Is there and easy way of doing this so on each page I only have to pass the values $info instead of each variable?

Monty Hall: And so, juschillinow, which door will you pick?

juschillinow: Umm, I choose, I choose, um .... number two!

Monty Hall: Door number two ... Sessions!! YOU WIN!!!(sound of cheering and applause)

juschillinnow

yep, I suppose that's going to have to be my choice (even though I think there should be another way to pass arrays as a single string).

I'm passing pretty sensitive info, and even though sessions are suppose to be more secure that cookies.... I still don't like it.

dalecosp

Hmm, the need for security would definitely outlaw hidden vars.

Session information should be secure on a dedicated server. If you're virthosted, I guess anyone can read (& write) /tmp...

The possibility of needing to pass SESSID in the URL is more "chillin", I guess ... are you using https: ??

Database? Flat files? ??

juschillinnow

yeah, https, mysql.... I think I might use md5 or something once all is said and done

dalecosp

I guess $_GLOBALS['info']=$info; would, theoretically, hold it in memory ... but would be subject to the same theoretical attacks as hidden post vars...

juschillinnow

one more quick question before I close this post:

when this gets passed
<input type=hidden name='info[test]' value='Hello'>

is it the same thing as if I had written it like this:

$info = array('test' => 'Hello');

dalecosp

That's what my setup does, anyhow...

//pass.html
<form action="pass2.php" method=post>
<input type=text name="this">
<input type=hidden name=info[test] value="Hello">
<input type=submit name=submit>
</form>

//pass2.php
<?

print_r($_POST['info']);

?>

Results in

Array ( [test] => Hello )
