Re: [PHP] Form Loop
I'm trying to create a form with a loop. I need to append a value to a
field name each time through the loop. For Instance:
while ($row = mysql_fetch_assoc($result)) {
$x=1;
echo "";echo "name='quantity_' size='2' value='$row[qty]' />";
?>
echo "";
$x++;
}
the name value quantity needs the value of x appended to it.
quantity_1, quantity_2 etc.
I recommend using array notation instead of appending $x to the element
name. If you are using POST, when the form is submitted the values are
available in the $_POST['quantity'] array. You can use foreach to
iterate through it.
Example:

There is no real need to use IDs for form elements unless you are
attaching labels to them. If you're using JavaScript to check for
certain values, then you can iterate the elements of the form in array
notation also. One more thing, you don't need to put explicit values
into form elements that use array notation, it's enough to put
Note the curly braces, you must use these if the HTML is being output by
PHP, or it will not know that the variable you are trying to use is an
array element.

[PHP] how to start using a version control system (subversion)?
Apologies for posting a monthly/yearly recurring theme here.. If someone can add links to previous discussions relating to the same, that could help too. I'd like to use subversion on a home unix server of mine to keep track of my projects. I dont even know what i need for a good intergration of subversion when i run my software on shared hosted unix and develop on windows. I've got windows shellintergration (a virtual drive) for all my remote storage, and atm use aptana studio as my editor. My home unix server is accessible (http & ftp atm) from the outside world.. My question is how to intergrate a subversion repository so that i can easilly checkout files on my windows development box (pref even from the editor; must support syntax highlighting too), and then update my sourcetree on the shared hosting (or another temp test server). If possible, i'd like to avoid using subversion commandline instructions and use a web-interface. Ofcourse, i can do some things with subversion cmdline instr and put that in a php file. I want to avoid as much (typing) overhead as possible for each operation i need to do. And i'd also like to know what visual interface to subversion most easilly manages the repository, creating/deleting branches from the main development line, etc. Please reply-to-all. Background: my motivation for using a version control system in the first place; The software i develop (http://mediabeez.ws) runs on multiple servers, mostly unix. On each of these servers, i use symlinks to point from sites .../www/site-name.com/mediaBeez to a common .../mediaBeez-1.x directory that contains the code.. The code itself uses the http hostname to determine which config-file (containing db and theme settings) to use. Up until now i havent used any version-control besides properly naming code directories and copying them with windows explorer after each significant change. This has worked fine up until recently. My software runs on shared hosting and not everything (like video conversions to flash video) can be done there on that shared server. So now my software runs on 2 servers at the same time, calling functions in the same php library file (lib_import.php). I had to keep both files open in my editor, and after each saveable change manually copy them to the other copy of the same file. That's no problem if its just 1 file, but i had 6 of them. Needless to say, it takes too much concentration if there are more files involved. Up to 5 files on 2 servers simultaniously is doable, but more than that is a real attention-drain and nuisance. My main development box runs windows vista. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Convert video to FLV like youtube
I use ffmpeg (unix commandline) to do the video converting.. ffmpeg needs to be properly re-compiled with mp3 support (for audio in the flv files); theres tutorials on google on how to do that. Are you on shared hosting? Most wont allow any kind of video conversion on shared hosting. I had to recruit my unix homeserver to do the video-converting for me. Took quite some code to get it to run correctly spread between the shared hosting main server and the video-conversion server...

Arrays are definitely the way to go, not only is it easier to process,
adding new rows on the form can be done with simple javascript then if

By tags I mean something like wordpress' implementation of it, for example when an author writes an article on babies the tags might be baby,babies, new borns, cribs, nappies or a picture of a baby can have the tags baby,babies, new born, cute kid, nappies the tags are comma separated above of course.

You're randomizing the whole array which when it gets large, will be
noticeable.
If you're using zero based arrays (like above - 'Neo' is item '0',
'Morpheus' is item '1'), I'd suggest something like this:
$input = array (...);
$num_keys = count($input);
$random_keys = array();
$num_to_fetch = 5;
for ($fetched = 0; $fetched < $num_to_fetch; $fetched++) {
$key = rand(0, $num_keys);
// if the key has already been picked,
// decrease "fetched" and try again
if (in_array($key, $random_keys)) {
$fetched--;
continue;

$random_keys[] = $key;

Take out the id attribute on the input element though, as these must be
unique for an element, and the only reason to use them in this case
would be if you had label tags giving the input boxes a name.

As to your other question, I think that the best idea is to have a separate table for the "tags", and link them to the unique id of the row on the main table that contains the content. This way, searching for specific tags, and producing counts (for weighting individual tags) is an absolute doddle, and can be done with pure SQL rather than retrieving all the information from the database and have PHP do the donkey work.

Probably it is possible to avoid but if shuffle fires inside the loop, reshuffling seems like it would be an issue.

[PHP] Best way to recieve image from url?
Hi,
I have this function:
function saveImageFromUrl($image_url, $image_save)
{
$contents = file_get_contents($image_url);
$fp = fopen($image_save, 'w');
fwrite($fp, $contents);
fclose($fp);
}
As you can see it fetches the images contents and write them to new image on
my local directory.
Is this is the best way to do this? (I don't have curl)
Does file_get_contents() uses buffer to get the contents of the image? (in
case the server response is slow)
There is a better way?
Thanks in Advance,
Nitsan

the server will respond slow either way if it is slow to respond.
There is a better way?

(I don't have curl) Do you have GET or wget on your server, with exec() privileges to use them? Your method is good for cross-platform usage, but won't follow redirects. > Does file_get_contents() uses buffer to get the contents of the image?

As Borge suggested, it won't speed things up for you if the remote server is slow, but if I understand you correctly, you want to know if there's a way to keep it running on your end. Check into either using it as a cron job, a forked process, or by setting max_execution_time and ignore_user_abort(), et al. -- More full-root dedicated server packages: Intel 2.4GHz/60GB/512MB/2TB $49.99/mo.

If you're using file_get_contents, why aren't you using file_put_contents?

They are (more often than not) just special cookies themselves, and the only bit of information stored is the session id in the cookie, and the rest is stored in server memory (or sometimes a text file on the server.) The chances of someone forging this is much less, and if you use sessions with https then this is reduced much more, but at the end of the day, nothing is foolproof...

No, they are not. In the first statement, $search is the value of
$_GET['search'] if the key exists, or an empty string if it does not.
In the second statement, $search is the value of $_GET['search'] if
the key exists or retains its original value if the key does not
exist.

Yes, I didn't realize Yeti had changed the OP's code which convoluted
the issue since his version wasn't what I was responding to and I didn't
realize he dropped a line from the OP's code.
Cheers,
Rob.

Yup. :-) Those are the ones that get you. Especially when it happens
in actual code and not just a mailing list post.
