How to use array function

Anon

Hi
My problem is that I need insert lot of values with
a form but I have to see history wich names I already have
inserted and after then execute insert query.
One possible way is to using temporary table but I have
all the time create this temporary table, insert values into form,
update some values in temporary table,
export all values from temproary table
into another table and after delete this temporary table.
But how is possible use array against this temporary table???

Lauri.

My suggestion:

Use cookies or session management functions in PHP4 to store the values.

1 - store the values in an array
2 - serialize the array and store it in a cookie
3 - When the user submits a new form read the cookie, unserialize the array and do what you need with values then process to step 2
4 - When the user commit his job read the cookie, unserialize the array and store the result in your db.

You don't need to create a temporary table.

Hope this helps

ps:
- serialize and unserialize functions syntax can be found in the php manual at section "Miscellaneous functions"
- SetCookie: "HTTP functions" part
- Session management: "Session handling functions"

From Steven van poecke in the "General Topic"

                            To store an array in a cookie: 

                            <? 
                            // create the array 
                            $myarray = array(); 

                            // store values in the array 
                            $myarray[value1] = $value1; 
                            $myarray[value2] = $value2; 
                            // ... 

                            // serialize and urlencode the array 
                            $serialized = serialize($myarray); 
                            $urlencoded = urlencode($serialized); 

                            // set the cookie 
                            setcookie("mycookie", $urlencoded, time()+3600); 
                            ?> 

                            To retrieve the array from the cookie: 

                            <? 
                            // urldecode and unserialize cookie value 
                            $urldecoded = urldecode($mycookie); 
                            $unserialized = unserialize($urldecoded); 

                            // extract values from the array 
                            echo "value1=$unserialized[$value1]<br>"; 
                            echo "value2=$unserialized[$value2]<br>"; 
                            // ... 
                            ?>

Hope this suit your needs
