Processing Array Values

[obrienkev]

Hi all,

Below I have created an array and need to pass it through a few pages where it will then be split up...

1/ Array Created here...

<select name="ffnumber[]" id="ffnumber" multiple size="10">

2/ In Page2 variable posted...

$ffnumber = $_POST['ffnumber'];

Then set in a form...

<input type="hidden" name="ffnumber[]" value="<?php print_r($ffnumber) ?>" />

3/ On Page3 variable is gain got...

$ffnumber = $_POST['ffnumber'];

then I want to split the array values...

// FORMAT FFNUMBER DETAILS
foreach($ffnumber as $k => $m)
{
    echo '<p>'.$k.' => '.$m.'</p>';

    // FORMAT FFNUMBER/NAME
    list($ffnumber, $surname, $firstname) = split('[/.-]', $m);

$query= "SELECT..."
}

Problem is that the query is performed for the first array value only.

Why is this? Thanks.

it may be because of the print_r();
print_r actually prints out an array on multiple lines, and HTML can't handle that, it only things it has one line and then it has a bunch of line breaks. Use implode and seperate them by commas.

I changed the Hidden Field to this...

<?php foreach($ffnumber as $value){ ?>
<input type="hidden" name="ffnumber[]" value="<?=$value?>" />
<?php } ?>

In View Source it displays as...

<input type="hidden" name="ffnumber[]" value="pg0983-Aoe-L" />
<input type="hidden" name="ffnumber[]" value="ff1383-Ahe-A" />
<input type="hidden" name="ffnumber[]" value="pg9991-Ang-S" />

Then on the 3rd page I want to pass that array...

$ffnumber = $_POST['ffnumber'];

And for each value to perform a query...

foreach($ffnumber as $k => $m)
{
$query = "...";
}

However, the whole query is only performed for the first value.

Why is this?

Thanks.

Actually I discovered it breaks here...

function addslashes_mssql($surname){
    if (is_array($surname)) {
       foreach($surname AS $id => $value) {
           $surname[$id] = addslashes_mssql($value);
       }
    } else {
       $surname = str_replace("'", "''", $surname);  

    }

return $surname;
}

// Call Function
$surname = addslashes_mssql($surname);

Any ideas why this is?? I'm using MS SQL Server as DB and there is no function for adding slashes like for mysql.

Thanks.

Why are you sticking all these values in hidden fields in the first place? Wouldn't session storage be safer? Or is the form on one domain and submitting to another?

[obrienkev]

I'm not sure how to use session storage.

You would first start a session using session_start() then assign all your variables as session variables. Wherever and whenever you want. It would save a lot of codeing. You could take each array value and assign it to session variables lik from you form right after you post them to the next page like this

<?php
session_start();
$_SESSION['var1'] = $_POST['var1'];
$_SESSION['var2'] = $_POST['var2'];
$_SESSION['var3'] = $_POST['var3'];
$_SESSION['var4'] = $_POST['var4'];
$_SESSION['var5'] = $_POST['var5'];
//more code here
...
?>

Now that you have set these session variables they are always available on any page as long as the user is logged into your site. The only thing you need to remember is that you must first use session_start() to be able to either assign or read them. Also the session_start just like the header() funtion can not have any output prior to using it, so usually just placing it at the beginning of your script will avoid the cannot modify header sent in line such and such in file such and such.
