Using an array and inserting ids from a mysql table until the array has 6 items

[brown2005]

Hi, I want to have an empty array then when I load a page it will get the id of the mysql data an insert this into the array, up to a maximum of 6 times..

 

I have no ideas how to set or update arrays, so  any help will be much appreciated

You want to learn about arrays in php??

 

Try the php manual?

 

Or is it something else you want?

[brown2005]

$numbers = array();

 

so now say I have 

 

while($row = $stmt->fetch(PDO::FETCH_ASSOC)){

 

$id = $row['id'];

 

}

 

how do I add that $id into the $numbers array?

Type in "array"

 

All kinds of useful things there you are going to want to know about.

$_SESSION['numbers'] = array();
array_push($_SESSION['numbers'], $id);
print_r($_SESSION['numbers']);

So I have this code, which gives me the array:

 

Array ( [0] => 9 )

 

but what I want to do is store this, so that every time it refreshes it will keep the last time plus the new number?

So I'm gathering you are using your page to capture one id at a time and want to save them all, up to 6.

 

When you process each page submitted, add the new $id to the session var that you have created.  Check how many there are and if less than 6, repeat.

 

After six, I don't know what you want to do.

 

Do I have to write the code?

[brown2005]

yeah thats exactly what I want to do, but the code I currently have only adds a new $id each time, so always one id, not extra

Well, you're using a session variable so each new entry should be saved from each iteration.  Of course, if you execute that line:

 

$_SESSION['numbers'] = array();

 

each time thru, then what do you think that is doing?

[brown2005]

creating a new array each time? 

[ginerjm]

Tada!!

 

So only create the array when you load the page for the first time. 

 

if (!isset($_SESSION['numbers']))

    $_SESSION['numbers'] = array();

 

 

Then each time you process your $_POST and add an entry, do:

 

if (count($_SESSION['numbers']) < 6)

{

   (redisplay your page and exit)

}
