Array problem ??

Anon

Hi all,
I have got mutiple selection list box and I can read the values through "count($selected_list); and got the values also with "for" loop. But the problem is ..How could I send this Array(Multiple selection) through query string to furter pages ?? Means If I want to receive the Multiple selectd values from another page which is not exactly called on the form submission. As I already try to passed this multiple selected value by Query String like "/new/nextpage.php3?$selected_values".. but the value dosent go.. What's wrong ???

Thanx

you can use implode() to print the values in a string like this:

echo implode($array,"|");

that will print a string like: "1|2|65|87"

your can pass this to the next page through the URL.
Then on the next page you can use explode("|",$string) to turn the string back into an array.

Hi Vincent,
The situation is.. When Form is submitted it gives a multiple selected value to "a_file.php3" and I can receive and search through the dabase very well. But now I want to pass this multiple selected value again to another file through Query String like "second_file.php3?location=$multiple_selectedvalue"..as you told me about implode() and explode()..it dosent seem to working..It passes the value only "Array" to the second file.. ?? If I am unable to make you understand please tell me send the coading what I am doing ??
As you always helped me this time I also hope so..

in your first page:

$a=array(1,2,3);
$string=implode($a,"|");

echo "<a href=blabla.php?myarraydata=$string>click me</a>";

in your second page:

$array=explode("|",$string);
echo $array[1];

How about formatting your array as a string like this: ar_name[]=value0&ar_name[]=value1 etc. For example:

<?php

$qs = '';
foreach ($my_array as $val) {
$qs .= "&my_array[]=$val";
}

Then you can append $qs to your link URL and you'll have the same array in the next page.

Or, you could use PHP's session functions to save the array for the session.

How could I have missed that one. That's how PHP get's it's array of selectbox data in the first place, and bunch of values named like an array.

Thanks Keegan!
