No, you can't do this. Functions within the class can automatically get
to class variables with $this->something, so passing them as parameters
would be somewhat redundant.
class Something
{
var $something;
function Something()
{
$this->something = "More somethings";
}
}

When you are doing you select try something more along the lines of:
select date_format(date, '%e,%c,%Y') from tblmycoolstuff;
I got most of this stuff from
http://www.mysql.com/doc/D/a/Date_and_time_functions.html You need to look
at the table on that page to get the date to print out exactly as you want
it. I know date_format works with the timestamp column type, but I don't
know (but I assume) that it works the same exact way for some of the other
types that store dates :-)
If you still are having trouble, maybe I could help you?

Hi Guys
I'm having a bit of a problem with form submission. I'm creating an opinion
poll, and the user's vote is submitted as a form back to the originating
page. I'm using !isset to see if the form has been submitted and if so,
updating the database and showing the current results
My problem is that a user, having voted once, can keel clicking refresh in
their browser and the form data keeps getting sent, incrementing the poll
results each time
Is there a way to kill form data once it;s been posted, or is there a better
way of doing what I am trying to accomplish?
Many thanks
Lucas Young

The easiest way to stop most multiple votes is to send them a Cookie when
you get their vote.
If they have that Cookie, they can't vote again.
That won't stop a semi-serious cheater -- He'll just not accept the Cookie
or delete it after he gets it or...
If you need better than this minimal "honesty" factor, it gets tricky...
And *NOTHING* online (via HTTP, anyway) can be anywhere close to a reliable
voting method. Even Florida had it better. :-)

Dear friends,
I am accessing MySQL database using apache and php.
I have to display a double integer field without trailing zeros.
The number of digits after the decimal point varies.
I have tried searching the archive and did not get any previous questions.
Kindly help me in this regard.
Thanking you.
Sincerely,

No, once you register it, it's there unless you 'unregister' it.

I don't think you can do a Location and a Cookie in the same page, and the
Sessions are done with Cookies, so...
Don't do that.
Sorry.

So, like, are you sure that ++ really happens after the array assignment is
done?...
I'm probably just a Luddite, but I don't trust ++ and assignment operations
*that* far.

This looks suspicous... I'm not quite sure what's going on here, but I'm
expecting you'd want to walk from node to node, or maybe skip any
duplicates, but why are you zipping through the entire array looking for the
node that you are on?...
There's got to be a better way to track this -- maybe just using an indexed
array for your nodes, and knowing that you are currently on $node_index or
something...
Is a "node" an array? I wouldn't be using == on two arrays... Maybe it's
fine, but again that Luddite factor works in, and I'd be testing the
elements individually...

You could be using "variable variables" to do that, but for checkboxes, it's
way more better to use arrays:
<INPUT TYPE=CHECKBOX NAME=checkbox[1] VALUE=42>
<INPUT TYPE=CHECKBOX NAME=checkbox[2] VALUE='Life, the Universe, and
Everything'>
Now your processing page can just iterate through $checkbox:
while (list($key, $value) = each($checkbox)){
echo "$key -- $value was checked<BR>\n";
}
Only thing to watch out for -- If nothing is checked, $checkbox won't be an
array, and each() will give an error message.
So add this above that:
if (!isset($checkbox)){
$checkbox = array();
}
This checkbox/array stuff is in the FAQ, so read that http://php.net/FAQ.php
and the "variable variables" is in the online manual also.

TIP: Use "View Source" in your browser to see what the IMG tag looks like.
I suspect you've forgotten that you're not in PHP mode, and are just sending
a very oddly-named image tag, literally:
"$filedir/$CUserName"
Since the quotes are going there, I guess HTML is going to ignore the .jpg
part, or treat it as an unkown attribute.
I'm guessing you want:
<img src="<?php echo $filedir, '/', $CUserName, '.jpg';?>">

Yeah. That's called "eval" (short for 'evaluate')
Basically you can make PHP execute arbitrary chunks of more PHP code.
NOTE: Letting web-surfers insert PHP code into your database to be
evaluated later is really high on the Bad Idea list... Actually, doing this
on a web-site where you're not pretty sure the database itself is pretty
secure from not only surfers but also other potentially malicious co-users
on the same box... It's just too easy for them to be able to put mean code
in your database...
http://php.net/eval
I *think* it goes like this:
<?php
$php = 'echo "Hi";';
eval($php);
?>
Never used it myself...

Having quotes on the $file arguments to filesize() is not right...
Hey, doesn't filesize() take the *path* to a file, not a file pointer?
Yeah, it does: http://php.net/filesize
So, like, you're asking for the filesize of a file named '1' or whatever the
file pointer id number is.
Actually, I don't think you can get a filesize() of a URL anyway...
You're going to just have to get like a million bytes or whatever you think
convenient, and loop until you got it all.

select count(*) from users where userid = '$userid' and password =
password('$password')
might be a good choice.
Actually, I usually like to check userid first, and then password -- I
prefer to inform the user if their username is wrong or just the password.
Lord knows I've got enough usernames/passwords on all these darn sites that
I sure appreciate it when somebody tells *me* I ain't even remembering the
username right, much less the password.

I know this must have been asked before so I apologize in advance...
Is there a way to flush the $PHP_AUTH_USER / $PHP_AUTH_PW vars? I have a
routine where someone can logon to my admin section as a guest and enter a
new username/password. Is it possible for him to then logout (flushing the
guest vars) and re-login under his new u/p?
Thanks in advance

Sort of. Thanks go to Kristi as well for spotting this, PHP has so many
bult in functions already!
The only problem is that the site host doesn't have this functionality
installed, and as its a free host, I won't bother asking them. What I
will probably have to do is make my own function/class using a great big
list of words. Does anyone know where I could find a text list of every
word in the English language ;-)

Richard,
THANK YOU!!!
I agree -- this method provides many security vulnerabilities and I appreciate the
warning. The database is definitely secure -- from web-surfers and others. Also, I
intend to parse the information going into the database myself -- using a simple parse
engine I will create -- before making it accessible to PHP later. :)
I have designed a class-oriented language based on PHP, and these are the functions I
want available to my clients. I will filter out all other commands that could be
considered malicious. They will only have access to the functions and variables used
in the class language I wrote when I am done.
What do you think?
Thankz again!

I've a mySQL db with user information (e.g.: name, address, phone, etc.).
I'd like to pre-load an HTML form with the existing user information in
order to enable the users to update some of the information.
Are there any PHP sample scripts that I may look at to do this?
Thank you!
Do you mean, like if they are editting their profile, their existing one
shows up in the text box?
Here is a chunk of code I wrote to do that this morning:
-------------------------------------------
<?php echo("<form method='POST'
action='upload.php?school=$school&teacherusername=$teacherusername'>"); ?>
<!-- here is the part you might be looking for --!>
<textarea rows="13" name="assignment" cols="51">
<?php
$DB_NAME = "hwnet"; //Sets $DB_NAME
equal to "hwnet"
$connection = mysql_connect("localhost", "youruser", "yourpass");
//Attempts to connect to the server
$db = mysql_select_db($DB_NAME,$connection) or die("Couldn't select
database!"); //Attempts to connect to the database
$sql = "SELECT * FROM $TABLE_NAME WHERE username =
'$teacherusername' AND password = '$password'"; // This SQL statement
calls up the table and looks for a username and password match the ones
specified
$result = mysql_query($sql,$connection);
while ($row = mysql_fetch_array($result)) {
$assignment = $row['assignment'];
echo ("Previous assignment:\n $assignment");
}
?>
</textarea>
<!-- end part your probably looking for --!>
<input type="submit" value="Submit" name="B1"><input type="reset"
value="Reset" name="B2"></p>
</form>
-------------------------------------------
What this code did was take the existing info in the database, echo it out
to a array and then display it inside the text box.

When uploading a file, the built in functions let you get the filename,
size, type. If the file is an image, is it possible to also get the width
and height of the image?
Right now we are giving input boxes for the user to enter the correct
values, but I'd rather that my code do it for them. That way I can prevent
images that are too wide, as well as not depend on the uploader being smart
enough to know what the dimensions are.
Can anyone help me out?

I have a problem in my database(MySQL), this is the senario:
I made an update statement on my table by wrong, then I restor my backup
copy by copying the backup files on the exist ones without stopping the
MySQL.
Now I have problems in searching data:
for example when I made select statement using = , no results, but when
I use %% I can get the result, this thing not happend with all records,
just some of them.
any help will be appreciated.

$num=count($bannedwords);
for($i=0;$i<$num-1;$i++)
{
$string =
eregi_replace("\b$bannedwords[$i]\b","[censored]",$string);
}
For whatever reason, no word in $bannedwords will match in the string. I've
tested it with simple expressions like "\btest\b" and it will not match the
word "test". Does it have something to do with the 2 "\b"s found in the
code? After removing them, it replaces all instances of $bannedwords, even
in the middle of words, which is not good. Any suggestions?

Have you tried it with either "[:space:]$bannedwords[$i][:space:] or
"\<$bannedwords[$i]\>" yet? Also, I think using a foreach($bannedwords as
$current_word) would be a better choice here; more compact, and loops all
the way to the end of the array even when the numerical index does not
follow the expected sequence. (BTW, if you want to stick with the for()
and you know the index numbers will always be sequentially zero to
whatever, then your test should be just $i<$num. Otherwise, you're
skipping the final loop.)

Hi Debreceni,
I need to use a template parser, and XTemplate looks like it will do what I
need, but I'm not sure how. I can use mysql_fetch_array to produce an array
of field_name:value. If I use {field} names in the html template, can I use
XTemplate to take the array and parse?
This is what I have so far - please look at the ASSIGN step
<?
$id=1; //parameter for sql select, determines which row is selected
$user="user";
$pass="pass";
$database="database";
$sql="select * from table where id = $id"; //returns ONE row (id is a PK)
$link_id = mysql_connect($database); //identify connection handle
if (!$link_id) { die(sql_error()); } //test for connection handle
else { mysql_select_db($database, $link_id) } //select database
$result = mysql_query($sql, $user, $pass); //return row to php
$page_array = mysql_fetch_array($result);
//this creates array of field name:data,
//eg $page_array[firstfield] has value of 'firstfield' for $id
require "xtpl.p"; //include XTemplate engine
require "html.xtpl"; //html layout file with field names e.g. {firstfield}
$xtpl->assign($page_array); //HELP! How is this step done?
//I already have an array that assigns field
//names to data elements, how can I skip this?
//I don't want to assign each element since then
//I would need one .p page for each .xtpl page
$xtpl->parse("main");//replace {field} with matching result row element
$xtpl->out("main");` //send final html page to browser
?>
Does this make sense?
Thanks in advance for any help!
Regards,
Jaxon
require "xtpl.p"; //include XTemplate engine
//don't need this - wrong.
> require "html.xtpl"; //html layout file with field names e.g. {firstfield}
You need to create a new instance of the Xtemplate class so:
//assign the new instance to a variable name you'll use - I called it
$template
//and I specified which "html layout file" to use.
$template = new Xtemplate("html.tpl"); // I name them tpl not xtpl *shrug*
while($row = mysql_fetch_array($result))
{
$template->assign("FIELD1", $row[fieldname]);
//FIELD1 being the name you're going to use in the layout file by
{FIELD1}
//$row being the name of the array you fetched, field name being the
fieldname in the database
$template->assign("FIELD2", $row[fieldname2]);
$template->parse("main");//replace {field} with matching result row
element
$template->out("main");` //send final html page to browser
}
