[ARRAYS] Passing array as URL parameter

[flaab]

Hello 2all =)

 

I'll go straigh to the point. I'm programming a little search engine for my site.

The search function returns an array with the ID's of the databases retrievals for the users criteria.

 

Example: $retrievals = array(2,56,57,190,257,346,...,whatever);

 

And i want to split the results to view only 20 per page.

 

So, i need to pass that array as a parameter for an url.

 

Example: <a href="whatever.php?retrievals=<?php print $retrievals; ?>

 

And let the array be received by another document.

 

How can i do that?

 

Is there a better way to do this?

 

Thanks a lot.

you might just have to pass the array through the URL then break up the array on the desired script. Never heard of this before but its worth a try

[flaab]

Nope...could you be a little more specific? =)

 

U mean converting the array to string...and then joining it back?

[flaab]

Solved.

 

I pass a string made like this: $string = implode(",",$array);

 

And then I explode it again.

 

Thanks.

A better approach what I think would br serialize it and then unserialize it on next paga

 

$strRetrievals = serialize($retrievals);

 

<a href="whatever.php?retrievals=<?php print $strRetrievals; ?>

 

and on next page you can use

 

$strRetrievals = $_GET['retrievals'];

$arrRetrievals = unserialize($strRetrievals);

 

hope you find it useful for future use.....

actually, what you're talking about doing is called pagination, which is done an entirely different way... use the search tool on the forums.

If I understand correctly you are better doing for loop

 

Google PHP for loops
