Query About Empty POST Arrays
I started programming in PHP recently and have a query about empty
$_POST arrays. I can see two scenarios when this could happen.

1. When some tries to directly load the page to which data is being
posted (for example, opening www.foo.com/xyz.php directly when a form
action is xyz.php)
2. When the user clicks the submit button without entering anything.

I am aware that Javascript validation can take care of the second case,
but it's unreliable. What is the accepted way of handling the above
situations on the server side?
Do I just reload the calling page if the array is empty?

PHP Code For An Empty MySQL Query
I'm working on coding a system that will create a user row in a table, but first, I need the system to check initially to make sure if there is the need to do it (IE: if no row exists for said user). Right now I have it set up to pull out the following:

$permissions = "SELECT forumid, memberid, setupstatus FROM user WHERE forumid = " .$_COOKIE['bbuserid'];
$permquery = mysql_query($permissions);

I want it to check the table to see if there is a row for someone with a specific forumid (I use vBulletin, but it only relates in this case for the cookie). IF it shows up that there is a row, I want it to set $memberstat = 2; so that I can use that variable for various other page functions. If it shows up empty, it will set it equal to 1. How can I achieve this?

MySQL Query Returning Empty Column
Here's my code:

$query_get_machine = sprintf("SELECT machines.ID, machines.NotifyID, machines.Name, notify.ID, notify.`Data` FROM machines RIGHT JOIN notify ON machines.notifyID = notify.ID WHERE machines.ID = %s", GetSQLValueString($colname_get_machine, "int"));

Can anyone tell why the notify.`Data` column might be returned empty? All others display as they should.

MySQL Result Is Empty, But The Query Is Correct
I have written a script that grabs info from a database, and outputs it to a form. I figured I'd tidy things up a bit, and use a function to handle the queries, where I had previously hardcoded almost the same query several times. Code:

Query Syntax Issue
I have a query in my php file but i keep getting a syntax error but not sure what the syntax is precisely... this is what i got:

$query = mysql_query("INSERT INTO `hospital` (HospitalID,CountryID,UserID,Time,When,IllnessType)
Values ('1','1','$ID','7200','$Date','Autumn Flu')")
or die(mysql_error());

And i get:
QuoteYou have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'When,IllnessType) Values ('1','1','72','7200','2007-11-11 23:19:59','Autum' at line 1

Just to add Time = Integer and When =date("Y-m-d H:i:s",time()); format just so you know encase you might have thought it was my time input.

---

Date Range Query Issue
I have a database which contains events, the structure has two date fields, one is called "datefrom" and the other one is called "dateto", these two fields contain dates in the format YYYY-MM-DD.

"datefrom" represents the start date and then "dateto" represents the end date.

I have a query which returns all rows which have todays date within the start and end date, but it doesnt seem to be doing this correctly all the time, if at all. Can anyone spot any issues I might have with it?

My query is

$eventssql = "SELECT * FROM events WHERE type = 2 AND datefrom BETWEEN CURDATE() AND CURDATE() + INTERVAL 6 DAY OR dateto BETWEEN CURDATE() AND CURDATE() + INTERVAL 6 DAY LIMIT 10";
$eventsquery = @mysql_query($eventssql,$connection) or die(mysql_error());
Make any sense?

Small Issue With Sorting Query Results.
In the below code I am simply trying to sort a list of results in the category "Drivers" by price. I can achieve this fine but it only seems to take the first 2 digits of the price when sorting, so... Instead of sorting like:

€38
€70
€125
€175
€250
€370

Its sorts like:

€125
€175
€250
€370
€38
€70

$limit = 'LIMIT ' .($pageno - 1) * $max .',' .$max;
$query = "SELECT * FROM ads WHERE category = 'Drivers' AND validation = 0 ORDER BY '$price' $limit";

$result = mysqli_query($mysql_connect, $query) or die (mysqli_error($mysql_connect));

Ftp_nlist Returns False For Empty Directory Instead Of Empty Array
In an application installed with PHP5 it looks like ftp_nlist() returns
false if the directory is empty, instead of an empty array as it should
according to the manual. On the original server with PHP4 it works as
expected.

Is this a bug, or an undocumented change in PHP5, or a setting that
could be changed somewhere?

PHP Session Is Empty And Session File Is Empty
I am trying to save a SESSION variable which looks to succeed because right after I print it out to verify it. I do so as follows:

session_start();
<snip>
$_SESSION['security_code'] = $code;

The problem is that I submit a form on the same page and I need to check if the $_SESSION['security_code'] == $_POST['security_code'] however this condition is always false because $_SESSION['security_code'] is empty.  I also checked the security files that are created in the PHP 'save_path' directory and it appears to be creating an empty session file.

Can anyone suggest anything here?  Also prior to the condition, I also do a session_start() and that doesn't help either.

I got this code from a open source area and on that web site, if I test it it works fine.  On my localhost it does not work.  I'm not sure if I'm missing some configuration or whether PHP 5.2.2 has problems with sessions.

REGEX: Can't Seem To Replace LIMIT Clause In Query Using Preg_replace ($pattern, $replacement, $query)
Want to replace the limit clause in a query, but can't get it right.
What's wrong with this:

Help With Empty()
this is my php:

Empty If / Else ?
I have never done this, but I have an if/else statement, and if I don't want anything to happen in the if statement, should I leave it empty or is there something that I could add???

<?php
if(empty($_POST['fname'])){

}else{
     $name = $_POST['fname']
     mysql_query("INSERT INTO name(`first`) VALUES ('$name'));

How To Empty An Array?
I've got a nested array, which I populate while processing and formatting results from a query. When I print the contents of the array I want to clear it so that I can use it again in the next iteration of the loop without the stuff I've printed still in it. Is there a straight forward way to do this? I've tried re-declaring it but that doesn't empty it.

Htaccess Must Be Empty
I am moving some php scripts to a new host. While getting to know the

If I add a .htaccess file, or more specifically: a .htaccess with

results in internal server error messages.
If I upload an empty .htaccess file, all is fine. Then phpinfo() tells
me I am using Apache/1.3.27.

Sessions, Tmp Dir, Empty Files
Problem - the /tmp session files created in my tmp directory contain zero bytes (ie. totally empty). Any ideas why?

Here's my setup: Windows 2000, Apache web server, PHP402. I can see new session files being created each time a new session is registered, but they're not much use if they're empty! I've checked the file permissions on the tmp directory, and it's completely shared out. No error messages or logs are being generated that I'm aware of.

Thanks for any help...

Empty Arrays Or No Files
I have written a script which depending on the variable uploads $num files.
The value of $num is stored in a mysql column and each file is uploaded in an array $file[], then placed in a directory by the name $id_$i.jpg (for example).

The problem arises when I want to display the files back in a table. The $num is read back through the mysql query and if the amount of files is less than $num then I have a partially filled table. The cells with no filename display the icon which references "no image" as there is no file in the upload directory to reference.

What I would like to know is

1)if when the form is submitted and only half of the files are uploaded could I set the array so it realises that only half of $file[] has been filled, or that only 6 of 12 files have been uploaded.

2) Alternately, could I count the number of files in a directory on my server and store that value as an variable to set the number of columns in my table?

What would be the code for this???

Thanks in advance.

How Do I Not Print Something Out If A String Is Empty?
I am using mySQL to get stuff from a database, the fields are getting parsed into the variables $no , $t , $a , $l and $y

At the moment I am using this line this to display them to the web browser;

echo "$no: $t - $a [$l] ($y)<br>$n<br><br>";

However, sometimes $y is empty when the SQL query returns it's result and so if that happens I get something like

2000: blah - blah [whatever] ()
blah blah blah

Is it possible to add some code to my echo line that only outputs the () if $y is not empty?

I am sure this is possible but I havn't got a clue how to do it.

Empty Attachement Through Mail()
can someone check my code for me to see where I went wrong please?

I have made a short page where people can enter an email address and select a file to be sent to them. I have pillaged some code from some previous posts here which was very helpful. The script works more or less, however I have 2 problems:

1) The HTML isn't picked up in the body of the email, however the text is.

2) The attachment makes it to the email however when you open it up, its a blank file. The file name and size are correctly reported in the atachment.

Here is my code. I've also made sure the selected files are 777 on the server. If someone could take a quick gander, I'd really appreciate it!

Empty Fields For Every Record
If i have a table structure like in my attachment, how can i check for empty fields.That is, I want to check for every record in the table if lastname, street, zip, city and pwd are filled.

For example, in the second record that is with id no:2, street and city are empty.Similarly for the next record with id no:3, lastname,zip and pwd are empty.

So, idno:2 and idno:3 are incomplete.
Now, what i would like to do is, if i press a button, i want to send an e-mail to the respective e-mails which are in idno:2 and idno:3 that they need to fill their information again.

Could somebody please tell me how can i do this one?

Empty $_SERVER['HTTP_USER_AGENT']?
On several of my pages using this value, although Im not checking if it exists (which i think is most of my problem). When the function is called that uses this value, i get error log email, reporting that
"Undefined index: HTTP_USER_AGENT"

on the line number that the $_SERVER variable is used.

What should I do if something (web crawler possibly?) is hitting my website and not reporting a user agent. Im tempted to just do a redirect if this value isnt set.

$_POST Is Empty (in MSIE?)
Has any of You ever experienced the problem that posted forms deliver an
empty $_POST-array?

I have a form like:

<form method="POST" action="https://.../result.html?qid=70">
<input type="checkbox" value="1" name="1a">
<input type="checkbox" value="1" name="1b">
(...)
<input type="submit" name="Answer" value="Answer">
</form>

and every once in a while I get empty results (1 out of 10, maybe). This
only happens in MSIE 6.0, as far as I can see, but I'm not absolutely sure.
Some users have the problem all the time, some never.

I use https to connect and mod_rewrite to rewrite "result.html" to
"result.php"...
