Hi all,

 

I've got a session array added to on each page using the following:

 

$_SESSION['recently-viewed'][] = array('sport'=> $sport,'event'=>$currentevent,'market'=>$currentmarket);

 

I can get it to display (with no styling) using print_r($_SESSION['recently-viewed']) but what I need is to display and store each value in the array separately when retrieving. I've tried the following two attempts to no avail. Any ideas?

 

foreach($_SESSION['recently-viewed'] as $key => $val)

{

echo $val." = ".$key."<br />";

}

 

foreach($_SESSION['recently-viewed'][] as $key => $val)

{

echo $val." = ".$key."<br />";

}

If I hard code the variables, the following works ok.

<?php
$sport = 'tennis';
$currentevent = 'cup';
$currentmarket = 'bids';
$_SESSION['recently-viewed'] = array('sport'=> $sport,'event'=>$currentevent,'market'=>$currentmarket);
foreach($_SESSION['recently-viewed'] as $key => $val)

{
echo $val." = ".$key."<br />";
}
?>

Where are you getting the $sport, $currentevent and $currentmarket variables from?

My $sport, $currentevent and $currentmarket variables echo as should do before the statement.

 

It may be a problem with how I am storing it in the session i.e.

 

$_SESSION['recently-viewed'][] = array('sport'=> $sport,'event'=>$currentevent,'market'=>$currentmarket);

 

I'm trying to store an array of sport, event, market inside of another array called recently-viewed in the session.

If you look at my code above, you don't need the []

But doing it how you've coded it means I can only store one array in 'recently-viewed'.

 

I need to store multiple arrays inside that array.

Sorry, not a mind reader

You need to use something like this:

<?php
$sport = 'tennis';
$currentevent = 'cup';
$currentmarket = 'bids';
$_SESSION['recently-viewed'] = array( 
		   array ('sport'=> $sport,'event'=>$currentevent,'market'=>$currentmarket),
			array('sport'=> $sport2,'event'=>$currentevent2,'market'=>$currentmarket2),
			array('sport'=> $sport3,'event'=>$currentevent3,'market'=>$currentmarket3)
		 ); 
?>

Have a look at something like this, it might help you out

Not a reader either . I did say it was an array within array in my 2nd post.

Yeah that helped thanks. It seems to be a foreach within foreach. It was just the syntax I couldn't get my head around. The working code is below for anyone who struggles with the same problem.

 

-- STORING MULTIDIMENSIONAL ARRAYS IN SESSIONS --

 

// Each page adds its details to the array

$_SESSION['p'][] = array('sport'=> $sport,'event'=>$currentevent,'market'=>$currentmarket);

 

// Set up array within array

$_SESSION['recently-viewed'] = array('p');

 

foreach($_SESSION['recently-viewed'] as $key => $value)

{

//Transfer the name of each set into $rv

$rv = $_SESSION['recently-viewed'][$key];

 

//Loop through each field array

foreach($_SESSION[$rv] as $field => $value)

{

 

$sport = $_SESSION[$rv][$field]['sport'];

echo $sport;

 

$event = $_SESSION[$rv][$field]['event'];

echo $event;

 

$market = $_SESSION[$rv][$field]['market'];

echo $market;

}

}
