Re: [PHP-DB] Submitting form from a href
Skip,
Just so you know, there is a general PHP user's list available for
just such a request. It's rather high-traffic, so be warned.
Now then, on to the problem. I believe I've figured out a way to make
this happen. I've only tested it on IE 6 and Firefox 1.5.0.4, so your
browser compatibility may vary. I'll just post the scripts I used to
test it here and you can take what you need and run with it.
Here is the script that my form is built in:
--
html
head
script language=Javascript
function submitForm (letter)
{
document.search.letter.value = letter;//
Here's where we're
setting the form value 'letter' to the letter the user clicked on.
document.search.submit(); // Then, submit the
form.
}
/script
/head
body
form name=search method=POST
action=testingLinkSubmit.php
input type=hidden name=letter value= !-- If
this isn't
here, the Javascript letter.value code won't work, since form.letter
doesn't exist. --
input type=checkbox name=checky/ Search all
campuses
br
?
for ($i = 65; $i = 90; $i++)
{
$letter = chr($i);
print a
href=\javascript:submitForm('$letter')\$letter/a ;
}
?
/form
/body
/html
-
The receiving end of the form looks much as you might expect, it just
parses the form values:
--
html
body
?
if (isset($_POST[checky]))
{
print Checkbox value is: Truebr\n;
}
else
{
print Checkbox value is: Falsebr\n;
}
print Letter: . $_POST[letter];
?
/body
/html
And there you go! Let me know if you have any problems.

Hey all,
This is not database related, but I get the
impression this list entertains general PHP
questions? If I'm mistaken, flame away.
I need submit a form when a hyper link is pressed,
and have been trying all manner of onlicks, etc,
but have been unable to hit the right combination.
Here's the scenario:
I have the alphabet in hyper links with a check
box below:
form...
A B C D E F G H I J K.
[] check for all campuses
/form
What needs to happen is that when they click a
letter, which is a a href=... now, it submits
the check box value as well, to be read through
$_POST on the receiving end.
And of course I need to know what letter was
click, this I was trying to get through a
$_REQUEST var, but was not able to do so.
Any tips would be monstrously appreciated.

I think the only downside to that solution is that the primary key will continue to increment regardless of the day, and I think the original poster wanted: 20050105-1 20050105-2 20050106-1 ...etc. This would be a great place for a stored procedure, but I don't know if I can recommend running MySQL 5 to you. The most platform-safe way I can think of is to get a count(*) of the number of rows with today's date, add 1 to it, and stick that number on the end of the string you've created to insert into a varchar field.

One of the tables allows for a user to enter up to 5 choices. The table would look like this: I think you need to have a primary key that's unique per record. That would allow you to make modifications per record without worrying about the duplicated RecordID. As far as updates and additions go, I usually keep the two separate when designing applications. Being able to update multiple rows at once shouldn't be a problem, you just select all the data, display it to your users with the appropriate form elements (select boxes, check boxes and such), and index it in your form by the unique id field. I don't think it's necessary to delete the records and reload them, doing that adds database load and increases the chance that something will go wrong.

Re: [PHP-DB] select text from a text file
On Wed, 5 Jan 2005 11:58:59 -, Ed [EMAIL PROTECTED] wrote: Happy new year folks! The titlemight make this seem like an easy to answer question However here's the complicated bit (well for me anyway). In my text file that is written to by the users in a chatroom it looks like this: nickname||color||what the user is saying||user how can i make it so that if they have a private message when they press update it pulls the message from the text file and displays it in the frame but also deletes the text? You should be using a database for this, it makes things so much easier. That being said, here's one way to go about the text file version: Open the file, read through it line by line. As you read it, push the lines into an array. If you find a private message for the user, store that in a variable, and do not push it into the array. Finish reading the file. If there's a private message, you've got it in a variable, and you can overwrite the private message file with the array you've stored, which is all of the current private messages minus the one you're about to display. Please note, this does not scale at all, especially in the fast-paced world of chat rooms. You will likely end up with file locking problems if you proceed with the flat-file method. Also, how can i make it so that if in a drop down menu they select the word everybody it goes to a file called messages.txt and if they select user or user2 or user3 from the list it writes to private.txt is this at all possible? user and user2 etc arent hardcoded it's pulling the names from a list of online users. Are you talking about appending messages to a text file? In that case, you can have the dropdown submit with the message, and in the PHP code have a case for 'everybody' where it writes to messages.txt, and if it's not 'everybody', write it to private.txt with the username that was selected from the dropdown as part of the row.

Re: [PHP-DB] Loading large volumes of data

I need to load the words in the text file into the database in such a way that there is a single occurrence of each word in the table. I'm glad you found that the indexes worked for you. I was curious if your file already had one word per line? If so, you could do a cat | sort | uniq to pre-process the file and rid yourself of any duplicates to eliminate the need for the check altogether. I think that getting the data into a ready-to-load format before involving the database would be quicker overall. Not to disparage PHP, but I would use Perl for such an endeavor.

OK. The problem is I don't want the next highest number.
There are gaps in the UID sequence. I need to find the next UNUSED
number in the sequence which is rarely the highest number.
As far as I know, you'll have to write a little function to do that
for you. I don't know of a built-in database function that does what
you require. Assuming your application is PHP, Something such as this
might work (pardon the shorthand):
function getNextMissing ()
{
$result = select id from the_table order by id;
while (list ($id) = mysql_fetch)
{
if (isset ($lastId) ($lastId $id - 1))
{
$returnVal = $lastId + 1;
}
$lastId = $id;
}
return $returnVal;
}
You'll need to modify the function to handle there being no gaps in
the sequence (i.e. return $id + 1 if you never hit the logic in the
if), or for that matter, there being no id's. Otherwise, I think it's
a good starting point. Good luck!

Sorry, I left a bit of a bug in there. You should exit the loop at

The global keyword works a little bit differently in PHP. You need to
inform your function that your variable is global, as opposed to
declaring it as global outside the function. Like:
$link = database connection
function processData () {
global $link;
...
