irrelevant. The terms of service state:

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

There's a perfect working example in the manual: http://www.php.net/manual/en/features.file-upload.php

OK, I'm attempting this again:

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?

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???

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").

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 Gary

attached mail follows:
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).
