Problem reading array's, validation's not working.

[Ninjakreborn]

  I have started using wildteen's, and other people's advice on using array'ed sessions even for temporarily storing vast amounts of data when it deal's with a larger form.  I have a form split into 3 sections.
the first is small, the other 2 are considerably large.

  The thing now is that the form's themselves, the fields are getting filled into an array
[code]$_SESSION['temp'][/code]
That is the master array that contains all the other information
in it then you can access various variables within that array like:
[code]$_SESSION['temp']['firstname'];
$_SESSION['temp']['lastname'];[/code]
The temp session array is where everything is primarily stored.
I have 2 smaller array's called
actiontaken and classification
There are 2 sections of checklists, one will have an array called actiontaken the other will have one called classification,  so in the end I will have the
$classification['variablename'];
and
$actiontaken['variablename'];
array's
I want to feed them into the bigger session array so there value's can be found like this
$_SESSION['temp']['actiontaken']['firstname'];
that would access the firstname field informaiton which is in side the array "actiontaken", inside the "temp" array, inside a session.
Then also I wuold need access to the variables that were in the original array, like
$_SESSION['temp']['variablename'];
as well as the one's from the sub-array's when needed, like
$_SESSION['temp']['classification']['variablename'];
So the point is I need to be able to put smaller array's, inside larger arrays while still having some variables in side that one array.
I am afraid if I put the classification and action array, into the session array it might overwrite something??
How do I do this properly?
say once I collect the data, how do I put it all into the session at once, as a whole?

[wildteen88]

Just do something like this:

$_SESSION['temp']['actiontaken'] = $actiontaken

That will now copy the array from $actiontaken in to the newly created temp['actiontakem'] session

[Ninjakreborn]

Ok, so that should put the entire action taken array into the temp array.
So for instance if I had first name saved in that 2nd array, after doing that, I could use that by doing
[code]<?php
echo $_SESSION['temp']['actiontaken']['firstname'];
?>[/code]

[wildteen88]

Yes. As I said it copies what's in the $actiontaken array into the temp session array

Its no different to doing this:

[code=php:0]$someVar = 'someValue';

$sVar = $someVar;

echo $sVar // returns the string 'someValue'[/code]

Accept you're using an arrary.

[Ninjakreborn]

Ok this leaves me with one final question now that I realize that.
So if I can get an array called
actiontaken with all the variable(value combinations then I am good to go
How do I get them all into an array
do I have to manually put each field into an array
or because when I saw people name them
say
<input name="actiontaken[]" type="select" value="firstname" /> *just an example*
ok, I have a whole bunch of these, which is how I saw to name checkboxes.  If I do this, logically it looks like it's going to create an array of the values.
I need to be able to access the variables, like
$_SESSION['temp']['actiontaken']['firstname'];
and it contain I guess, I am not sure how this is going to work out?

Edit-
See I literally need the action, I don't know.
For instance
landing,
I need to know whether it was selected or not, but in a way I can database it, it's very hard to explain, if someone knows what I mean?

[wildteen88]

You need to do this then:

actiontaken[field_name_here] in the name attribute for each form field then, Example:

<input name="actiontaken[firstname]" type="text" value="firstname" />

[Ninjakreborn]

perfect, thanks
do I need to use the
['variablename']
the ' where they are, or is that not going to be needed since it's still html.

[Ninjakreborn]

nevermind I saw your edit, thanks again for the advice.

[wildteen88]

When you're naming your fields with associative arrays dont put quotes around your keys otherwise in your PHP code you'll ahve access then like this:

array_name['\'key_name\''] or array_name["'key_name'"] it will thing the quotes are part of the html.

[Ninjakreborn]

so this would also let me know if it was selected.
For instance if I did that in the name's.  Then fed them into the session['temp array or whatever
say I wanted to check to see if the variable router was selected.
I could say for instance if it was selected then the text box below it was required
[code]<?php
if (isset($_SESSION['temp']['actiontaken']['router'])) {
  if (!isset($_POST['textbox'])) {
  // text box required when selected
  }else {
  // not required 
  }

}
?>[/code]
Just an example, could it be used with that type of usage, and be reliable.

[Ninjakreborn]

I am running into a few problem's currently, this isn't working the way I need.
First I have to get validation down, then I have to get it to prefill back out the one's that were selected.
For now, the problem I am currently having is
ok if you look below you see on post 3, this is where the form itself is, and where I name the array's
then if you look on post 4 you see where I am attempting to validate the data.
At first I thought it was working, but it now doesn't care whether one of the fields of classification are field out or not, that is the first thing, Ihave to test whether one within that array was set.
I tried the obvious but it's not reading it right, it doesn't seem to care whether it's set or not, either way it's telling me they didn't check "anything" within classification.

THe next thing, is I had it set up, to test the array for the existence of the variable other, and a few other's but this is just an example, if other was selected the field should be required, it's not seeming to read that right either, as it's not even returning to me a message in my error handler when other or another one that I need to validate is checked.

These are just 2 of the problem's I am currently having, so it seems like I am not creating, or accessing the array's properly.  I think once I get help with this, then I will know then how to access them, and be able to get the rest working.

edit - Also yes, I know I used tables to layout the form, I got tired this time of fighting with the css, this time, it was murder.  So I did the form itself in tables, in a css layout.
I may start doing all my advanced form's like that, this one took me 2 day's to layout because of how big it was, it was split up into 3-4 parts.

[Ninjakreborn]

anybody?

[Ninjakreborn]

Ok, by some wierd chance, I learnt how to check the array's, to make sure if they were set, then the proper text field had to be set as well, I also learnt a valuable new skill for later projects.
However I can't figure out how to test the classifications array
in general to see if any were filled in
The only requirement right now, is that atleast 1 of them is filled out, I have tried the following code's and nothing has worked.

[code]if (!$_POST['classification']) {
  $errorhandler .= "You have to check atleast one of the classifications.<br />";
}[/code]

[code]if (!is_array($_POST['classification'])) {
  $errorhandler .= "You have to check atleast one of the classifications.<br />";
}[/code]
[code]
if (!isset($_POST['classification'])) {
  $errorhandler .= "You have to check atleast one of the classifications.<br />";
}[/code]

if ($_POST['classification'] == "") {
  $errorhandler .= "You have to check atleast one of the classifications.<br />";
}

None of this stuff is working, I went on to try 4-5 other variations but nothing is seeming to work properly, I don't understand it, any advice would be appreciated.

[Ninjakreborn]

I would be eternally grateful is someone knew:D

[roopurt18]

If it's an array, use count();

[Ninjakreborn]

I recently tried that, no luck, I tried counting it in the variable, I tried testing to see if it was 0, and if it was return an error, I don't know, nothing is working.
I just need to check the array, see if any check boxes under that array where checked, that's it, any advice?

[Ninjakreborn]

Well I echo'd out the count variable and it returned 5
so for some reason the default was 5, I guess the sub arrays I fed the array, counted out numbers even though no variables were set to those
so
[code]<?php
$n = count($_POST['classification']);
if ($n == 5) {
$errorhandler .= "You have to check atleast one of the classifications.<br />";
}
?>[/code]
Seemed to work, I tested it a few time's and it seem's to function is this going to be reliable int he future as well.

[roopurt18]

[code]<?php
  // test.php
  // Display a form that uses checkboxes as an array
  // Validate that at least one selection was made

  if(count($_POST)){
    echo "<pre>" . print_r($_POST, true) . "</pre>";

count() doesn't default to anything, it counts the number of elements in an array and that's it.  Picking an arbitrary number, such as 5, and calling that ground zero is not necessarily reliable.

yes but when I natuarlly counted the variables.  And simply outputed what the count variable held,without me checking any checkbox's, it started at 5.
So I ended up havnig to use that, it automatically set the number to 5

Place this code somewhere in the area where the form is being processed:
[code]<?php
echo '<pre style="text-align: left;">' . print_r($_POST, true) . '</pre>';
?>[/code]

Then submit the form without checking any of the boxes and paste the contents of the $_POST array here.

[code]Array
(
    [phaseofflight] => none
    [classification] => Array
        (
            [doorwarningwhichone] =>
            [dooropeningwhichone] =>
            [flightinstrumentwhich] =>
            [engineinstrumentwhich] =>
            [othertext] =>
        )

    [description] =>
    [submit] => continue
)
[/code]

This is what is outputted.

Here is the relevant piece of information:
[code]
Array
(
    [classification] => Array
        (
            [doorwarningwhichone] =>
            [dooropeningwhichone] =>
            [flightinstrumentwhich] =>
            [engineinstrumentwhich] =>
            [othertext] =>
        )
)
[/code]

Now do the same exact thing, but this time check one of the boxes associated with one of the following values:
doorwarningwhichone, dooropeningwhichone, flightinstrumentwhich, engineinstrumentwhich, othertext

I can almost garauntee your form validation will fail and tell you that you must check at least one box for the classification.  If you didn't check any boxes, none of those keys should exist inside [i]classification[/i].  They do for some reason and I'm not gonna pick apart your code to find out why.  But it just doesn't seem right to me.
