Posting Array's

TheDutchBeast · November 28, 2012

Hi there mates, I've got a question from a friend of mine. And I could not solve it and I am ashamed of myself haha .

The code is not yet complete, but what it has to do, is post the array, whick contains the names of the files uploaded ( pictures in this case ) The first post works, but thats it, it doesnt show the array on the last past it only shows "array".

Please help me fix problem, I translated a bit of the code from dutch to english, so it's a bit more clear

Thanks in advance

David

It's because you're trying to write it out as a string.

You'll either have to implode () it, or loop through it with a foreach () or similar. The PHP manual contains more information on both subjects, just type "php.net/{name}" in the URL and you'll be taken to the correct page.

Thanks christian, i just visited the page but it still it not quite clear to me.

Could you adjust a small piece of my code so I can see the difference. That would be great!

Thanks in advance

I can't view your code - my browser has issue with attached files on here - but all you need to do is add the following line just before the one that is used to echo the array (I'll call it $array for fun) to something like the following

$array = implode(', ', $array);
echo $array;

And now it is also giving me this error

Notice: Array to string conversion in C:\Program Files\EasyPHP-5.3.8.1\www\Infosysv3\INVOER\fotoinvoerpagina2.php on line 321

Array

Again how do I have to post the imploded strings to the next page?

Thanks muddy.

But is i implode it on the first page, does that mean i have to explode it on the page after?

My boss just told me another solution.

Passing array's via a session.

Any one familiar with this?

Christian F. · November 28, 2012

The PHP manual contains all the information you need on how to use sessions, including examples.

Though, to answer your question: Yes, I am familiar with sessions.

you would only need to implode it to display it with an echo statement. you're issue isn't passing the array from page to page, it's just getting it to display the contents of that aray when you get to the end. only implode when you want to output to screen, keep passing the array through as you have been doing.
