You are building something that will automatically scrape Google by
explicitly circumventing the tools they have provided for you to do so.
Whether the information is for your own internal statistics or not is
irrelevant. The terms of service state:

  queries" includes, among other things:

    *  using any software which sends queries to Google to determine how
       a website or webpage "ranks" on Google for various queries;

    *  "meta-searching" Google; and

    *  performing "offline" searches on Google.

Hi there. I am trying to write a routine to allow me to sort the contents of
a table by clicking on up or down arrows.
The idea is that top record will have down arrow, bottom record up arrow and
records inbetween  both an up arrow and down arrow.  Clicking the arrow
causes the record to move up or down one row in the table.  The hyperlinks
on the arrows would be used to move the record up or down one by switching
the sort order values in the records ie. you want to move a record one up,
the value of the sort order would be switched with the record above.

I have created a numeric sort field that I initialize with the same value
and the id field in my table. I have my database content in an array that I
want to use. So I want to create the table using an array of rows.  I can
get something basic to work if I do a count of my array to get the first and
last value.  I do a foreach and test the values in a switch
like:

            switch($itemcount) {

                case 1:
                    if ($itemtotal == 1) {
                        $arrows = '';
                    } else {
                        $arrows = "$downarrow";
                    }
                    break;
                case $itemtotal:
                    if ($itemtotal == 1) {
                        $arrows = '';
                    } else {
                        $arrows = "$uparrow";
                    }
                    break;
                default:
                    $arrows = "$uparrow $downarrow";
                    break;
            }
The problem I am having is to come up with a way to make this work when
there is more than one field to sort on.  I have a table with a list of
functions and files. There is a many to one relationship between functions
and files and I want the up and down arrows to work for sorting the
functions in the files in the list.  So that if a file has say 4 functions
the first would be down arrow, next two records would have both arrows, last
record for file uparrow, next record down arrow if file is different etc.
Could anyone help by giving me some advice on the best way of getting
something like this to work or have an example to follow. This would be
helpful.  I have checked the archives first but could not find anything.

Regards,
DAve

PhpNuke has something like this in blocks management. Try looking at it.

There's a perfect working example in the manual:

OK, I'm attempting this again:

header ( 'Location: ../test/test.php' );
sendByPost();
function sendByPost()
{
 $host = "localhost";
   $port = 80;
   $postdata = "field1=value1&field2=value2&field3=value3";
   if ($sp = fsockopen($host, $port)) {
     fputs($sp,"POST /jotr/test/test.php HTTP/1.0\n");
     fputs($sp,"Host: $host\n");
     fputs($sp,"Content-type: application/x-www-form-urlencoded\n");
     fputs($sp,"Content-length: ".strlen($postdata)."\n");
     fputs($sp,"Connection: close\n\n");
     fputs($sp,$postdata);
     fclose($sp);
   }
}

Pretty straight forward.  Now here's the code for test.php:
$temp1 = $_POST['field1'];
$temp2 = $_POST['field2'];
$temp3 = $_POST['field3'];
print $temp1.' '.$temp2.' '.$temp3;

But the data is not posting:
Notice: Undefined index: field1 in c:\apache\htdocs\jotr\test\test.php
on line 3
Notice: Undefined index: field2 in c:\apache\htdocs\jotr\test\test.php
on line 4
Notice: Undefined index: field3 in c:\apache\htdocs\jotr\test\test.php
on line 5

WTF is going on, shouldn't this work?

The other thing.. the header will redirect and the rest won't happen???

Hello,

I'm having a problem on my server where any time there is more than one
element in an array, all elements prior to the last one get a portion of the
beginning chopped off. This portion is pretty random (I have yet to find any
pattern) other than it seems if there is a space it will chop off anything
before the first space in a particular element. Every time a new element is
added to the array, more characters are deleted from the previous one(s).

This is best shown by going to
http://66.192.46.41/~serverso/phpBB/index.php - create a new post and add a
poll to it. As you add options to the poll, you will see the effect on the
other options which you had already created. This is not a phpBB problem, as
it occurs in other non-related php files on the server, but as I said this
illustrates the effect well.

You can also see what it did to a menu in postnuke on the server at
www.dmcstop.com.

Does anyone have any ideas???

Anyone help me? this is probably quite simple but I'm pretty new to PHP.
All I want to do it loop through some DB records and display them in the

Just checked the manual and there are no functions named *mysql_numrows* 
or *mysql_num_row*, but
only *mysql_num_rows* (notice the S at the end)

Actually, there *is* ("mysql_numrows").

I think you've missed this one. ;)

what about

if( $res->numRows() {
    while( $row = $res->fetchRows() ){
    ... do what you've got to do
    }
} else {
    ... no rows
}

Doesn't work, get unexpected { for if( $res->numRows() {. If I remove 
braces or rearrange them it fall apart piece by piece.

Thanks for the try

I very much appreciate the suggestions made by the people on this list, 
although for me, when developing, the less typing I have to do, the 
less errors I am bound to come across, and therefore the less debugging 
I must do. (Now, doesn't this seem sensible?)

Anyway, I have developed a function and incorporated Maxim's code 
(thankyou) to make importing variables (into global scope) easier (with 
register_globals turned off).

I have it sitting in my lib.php which contains all common functions 
(database functions, etc) that I use with my scripts and is included on 
every page I write.

To use my function, simply write:

importVars($_GET, 'var1,var2,var3'); // this will get var1, var2 and 
var3 from the querystring
importVars($_SESSION); // this will import all session information

This was tested with error_reporting set to E_ALL. Often in my code I 
will do something like this.

if ($flag){
        // do certain code relating to $flag
}

If $flag has not been initialized, this check will produce a NOTICE 
error, which appears if you are using E_ALL. So, my function will take 
all the variables you pass to it (through the comma-delimited string) 
and either import the variables (if it exists) or create an empty 
variable (zero-length string). This way you can do the check. I know 
some people will say, you could just use if (isset($flag)), but I like 
take advantage of PHP's automatic type conversion.

Another feature of my function is if you don't supply a string to vars 
to import, it will bring in everything from that array. This lets 
people import all the variables they want, and they don't care about 
security, or are protecting it through other means (extensive var 
checks) etc.

ie.    importVars($_GET);

So I hope this stuff helps some people out there.

Also, can anyone see any problems with my function? (Performance-wise 
or security-wise).

Adam
