I am almost ready with my learning project in PHP/MySQL.
I can register new product in stock.
Add and increase the number and weight.
I can move products between different storehouses
I can also transfer products from store and onto a "truck document" but
that's it and here I need some advice.

I like to register new products and the amount in number (for example 4)
and weight in kg.

I like to write it in this way:
Dynamite - package 4 - Weight 200 kg
Lunt - Package 10

Then I like to 4+10 = 14
and 200+10 = 210.

It shall looks like this:
======================================
Dynamite |  4  | 200
Lunt         | 10 |  10
------------------------------------------------------------------
TOTAL    | 14 | 210

It is easy to register this product by product on their own row.
but in what way can I multiply them? ned products be stored in arrays?
I think it will be similar to shopping cart in online store but i have no
clue about how to do this.
If you have links to pages were i can learn am i Happy for it. If you can
help me here is even better.

Thanks for your time and effort to learn me programming.

Ahhh.....
So - you should run a query that selects the products and information that you want. Then you start by creating an html table header and then loop through your query results and echo a table row for each result row. 

// start the table
echo "<table border=1>";
echo "<tr><th>Product</th><th>Amount</th></tr>";

// loop thru each item found
while ($results = $qrslts->fetch(PDO::FETCH_ASSOC))
{
echo "<tr><td>".$results['product_name']."</td><td>".$results['product_amt']."</td></tr>"; 
}

// finish the table html
echo "</table";

Yes that part is OK. I do have problem to add total weight and package at
bottom of the table like this:

Product_one   40kg
Product_two   60kg
-------------------------
Total:             100kg
===============

Because sometimes it is only a few products and other times many products.
I then need to summing them at bottom. One timer only 3 rows, other times
20 rows. The program need a way to add every singel product and see if it's
a few or many,

So - as you loop thru the results, accumulate your totals and then at the end before you close the table generate one last row with those amounts in it. Simple!

Hi all.

I have a requirement, wherein I need to allow vanilla uploads of files
to a HTTPD server.

Any client can upload any number of files (one at a time).
Also, there is just one directory, where the files get stored
"finally" (that is, after being copied from the temporary location,
via "move_uploaded_file")

Also, I have been able to get the simple file uploading running via
PHP, by picking up one of the numerous "Hello World" examples
available :)



Now, I am facing the following use-case ::

1)
User 1 starts uploading a large file, say "big_file.avi".

2)
Meanwhile, user 2 also starts uploading a (different) file, but with
the same name "big_file.avi".


In an ideal scenario, user 2 should be prompted with a message, that a
file of the same name is already being uploaded by someone else
somewhere.
Is there a way to do this?

( Note that, had the user 2 started uploading AFTER user 1 had
finished with the upload, we could probably modify the PHP-script at
the sever-side, to let user-2 know that a file of the same name
already exits. But I am failing to find a solution, when the user 2
starts the upload WHILE the large file of user 1 is in the process of
completing uploading).


Any way the issue may be solved?

I will be grateful for any pointers :)



Regards,
Ajay

The problem is not of PHP's making. It is something that you have to program around. Is the user determining the filename to be used? If so, then you need to check for that name before doing you "move". If it's a duple, then create a temporary name in your final place, hide it in the user's page and send it back to him with a message to change his name.
If the user is NOT determining the name, then your normal process would be to pick an unused name I presume and send That back to the user anyway, so problem never happens.

Hi,

This is not possible with PHP, PHP will not know about the file until the
upload is completed. You can use HTML5 or flash(not recommended) for an
alternative way of uploading, and then you can check the file name in
advance.

Thanks Jim and Matijn for the quick replies.

- Matijn
As Matijn said, you don't know the name until your php processes the file that has been uploaded alreaday. But my solution will work for you - you just have to save it under the temp name until the user responds to your message and request for a new title. You may have to run a periodic script to clean up any files with your temp names that the user declined to re-name for you. I'd make up a temp name with some special prefix so that you can find and delete them.

Is there anything that would prevent you from somehow uniquely knowing who
the user is uploading the file. For example you mentioned "client'.  If you
know
who the client is you can append that to the filename or prepend it, for the
destination string (second parameter to the function call).  That way it is
unique
to that client.

Thanks Jim and Anthony.

Jim,
You are right, your solution is doable.

But one thing I am a little skeptical about, is what would be the
percentage of the people willing to suggest a new name "immediately",
versus the percentage of people who would like to cancel the current
upload, and come back "later" after walking and coming up with a new name.

Anyhow, let me sleep over it :)


Anthony,
your solution is really a special case of Jim's solution :)



Thanks guys for the quick replies; I am obliged, really.

I will try to have a workaround.

Hi all.

I have a requirement, wherein I need to allow vanilla uploads of files
to a HTTPD server.

Any client can upload any number of files (one at a time).
Also, there is just one directory, where the files get stored
"finally" (that is, after being copied from the temporary location,
via "move_uploaded_file")

Also, I have been able to get the simple file uploading running via
PHP, by picking up one of the numerous "Hello World" examples
available :)



Now, I am facing the following use-case ::

1)
User 1 starts uploading a large file, say "big_file.avi".

2)
Meanwhile, user 2 also starts uploading a (different) file, but with
the same name "big_file.avi".


In an ideal scenario, user 2 should be prompted with a message, that a
file of the same name is already being uploaded by someone else
somewhere.
Is there a way to do this?

( Note that, had the user 2 started uploading AFTER user 1 had
finished with the upload, we could probably modify the PHP-script at
the sever-side, to let user-2 know that a file of the same name
already exits. But I am failing to find a solution, when the user 2
starts the upload WHILE the large file of user 1 is in the process of
completing uploading).


Any way the issue may be solved?

I will be grateful for any pointers :)



Regards,
Ajay




Hi,

This is not possible with PHP, PHP will not know about the file until

the

upload is completed. You can use HTML5 or flash(not recommended) for an
alternative way of uploading, and then you can check the file name in
advance.

That's why I said you would have to do a cleanup periodically. People who walk away could lose their session perhaps and the page wiht the hidden temp name buried in it, so they would have to do their upload from the beginning again. If they didn't lose their session and therefore that screen, then they could still respond and things would flow smoothly.
so - who is scanning these files for viruses and what not? It's one thing to host them but if you are going to let users view them on their clients you could be spreading things.

Another option is that you name the files yourself. Numerically for example and 
then just switch it back to the uploaded file name when either displaying it or 
sending it back to the user. 

You should also place all files outside the web root so it's harder to execute 
bad files. And prolly filter for files types. Allow only images ( png jpg gif ) 
for example

Try with mb_strlen
