passing an array

svenski

Is it possible to pass an array between two PHP pages? If so how? Sorry for such a newbie question 🙁

The_Chancer

Yeah - just like any variable really,

In the URL...($GET['var']) in a posted form ($POST['var'])

Thanks for your help, unfortunatley i have never come across this bit of PHP could you give me a better idea of the code?

Eg say i had an array $messagearray and i wanted to pass that to the page add_messages.php what code would i use in my original page that linked to add_messages.php to parse the variable and what code would i use in add_messages.php to pick up and use the variable?

TIA

If you wanted to pass $messagearray as a link (ie in URL)

<\"a href=next_page.php?messagearray=$messagearray\">Link</a>

Or in a form

and to get it $_GET['messagearray'][0]

or $_POST['messagearray'][0]

should get it back out in the next page

svenski

still having some problems, the array arrives empty... and the link in the URL appears as ?messagearray=Array when the link reads

echo "a href=campaign_message_addhold.php?messagearray=$messagearray Link /a"; (<> removed)

any ideas?

pick up code is:

	  $messagearray=$_GET['messagearray'][0];
	  echo 'Recieved ';
	  $totalmessages = count($messagearray);
	  echo $totalmessages;

Sorry - wasn't thinking....

Do it via the post method instead - won't work with it in the URL...

Still having no joy 🙁 perhaps you could give me an example of the post method? Can the form be outside the php code block or does the variable get deleted when the codeblock it was initalised in ends?

You cannot directly pass an array between pages.
Use the serialize/unserialize functions to encode the array into something html can handle. Or use the session system.
