How to count the number of files/images from a folder?

How do you count the number of folders in a directory?

I got to thinking late last night (which generally leads to trouble), so please be gentle if some educating is in order, as I suppose I will touch a few related issues.

As I develop my database, I will include two seperate columns.  One for the time/date that an order was placed.
A second for the time/date that an order is updated (unless there's a better way, please inform me).

I pressume that if a record is updated several times, it will continually overwrite the time/date to the point that I will only see the latest update.  Now I was wondering if I could create a third column to keep count of the number of times a record had been updated, so if it were altered 16 times, I would know when the last update occurred, and have the count number also.

Will something like this coding work?

SELECT updates FROM myTable WHERE id="$id"
$updates =n
if n<1, n=1
}else{ n++

hi, I want to count the total number of multiple select that user has selected instead of getting the value the user has selected How should I go about doing the counting part?

Code: [Select]
<form action="1.php" method="post">
<select name="test[]" multiple="multiple">
<option value="one">one</option>
<option value="two">two</option>
<option value="three">three</option>
<option value="four">four</option>
<option value="five">five</option>
</select>
<input type="submit" value="Send" />
</form>


<?php
$test=$_POST['test'];
if ($test){
 foreach ($test as $t){echo 'You selected ',$t,'<br />';}
}
?>

Hi. I have the following code where I grab the names and average overall rating from my database and group by the name.

Code: [Select]
$sql="SELECT name, AVG(overall) AS overall FROM $tbl_name GROUP BY name ORDER BY AVG(overall) DESC";
$result=mysql_query($sql);
while($rows=mysql_fetch_array($result)){
Does anybody know how I can count the number of names that have been grouped together?

For instance:

Name     Overal ratingl
John       2
Pete       5
John       8

It should group the john's, calculate the average rating (8+2)/2=5, and then show that there have been 2 johns making up the 5 rating?

I've tried using the code below and messed around with it loads but cant get it to work:

Code: [Select]
$sql="SELECT name, AVG(overall) AS overall FROM $tbl_name COUNT name GROUP BY name ORDER BY AVG(overall) DESC";
$result=mysql_query($sql);
while($rows=mysql_fetch_array($result)){

echo $rows['Count name'];
Thanks in advance.

Folks,

Having trouble here. Forgot how you use the COUNT. Not interested in the num_rows due to it being slow compared to COUNT.

I have users table like this:

id|username|sponsor_username

0|barand|requinix

1|phpsane|alison

2|mickey_mouse|requinix

Now, I want to check if a sponsor username exists or not. Such as does the entry "requinix" exists or not in one of the rows in the "sponsor_username" column.

In our example it does twice and so the variable $sponsor_username_count should hold the value "2". Else hold "0".

I get error:

Fatal error: Uncaught mysqli_sql_exception: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '?' at line 1 

 

My code:

	$stmt_1 = mysqli_prepare($conn,"SELECT COUNT(sponsor_username) from users = ?"); 
            mysqli_stmt_bind_param($stmt_1,'s',$sponsor_username_count); 
            mysqli_stmt_execute($stmt_1); 
            
            //Show error if 'users' tbl was not successfully queried". 
            if (!$stmt_1) 
            { 
                echo "ERROR 1: Sorry! Our system is currently experiencing a problem loading this page!"; 
                exit(); 
            } 
            else 
            { 
                mysqli_stmt_bind_result($stmt_1,$sponsor_username_count);     
                mysqli_stmt_fetch($stmt_1); 
                mysqli_stmt_close($stmt_1); 
                
                //Check if Sponsor Username in Url ($_GET) is already registered or not. If not then show "Invalid Url" or Link message. 
                if ($sponsor_username_count < 1) 
                { 
                    echo "<b>Invalid Url or Link!<br> Invalid Sponsor: \"$sponsor_username\"!</b><?php "; 
                    exit(); 
                } 
            } 
	

Hi guys

I'm kinda stuck..so hopefully you guys can lend me a hand

I've got an array containing date elements ("Y-m-d")...

I'm trying to output some data into googlecharts..so i need to count how many elements that are in the array with todays date -1 day, todays date-2 days...todays date -3days etc... Up until a set number of days (for example 7 days, 14 days etc)..

Any advice on how to go about to achieve this?

I have a database lets say punch_log

The data in the table looks like:
---------------------------------------------------------------------------
|punch_log_id |  user_id | punch_id |   punch_time           |
---------------------------------------------------------------------------
|   10010         |  21         |   1       | 2010-11-10 15:04:59|
|   10011         |  21         |       2       | 2010-11-10 15:50:05|
|   10010         |  21         |   1       | 2010-11-11 15:04:59|
|   10011         |  21         |       2       | 2010-11-11 15:50:05|
|   10010         |  21         |   1       | 2010-11-12 15:04:59|
|   10011         |  21         |       2       | 2010-11-12 15:50:05|
|   10010         |  21         |   1       | 2010-11-13 15:04:59|
|   10011         |  21         |       2       | 2010-11-13 15:50:05|
|   10010         |  21         |   1       | 2010-11-14 15:04:59|
|   10011         |  21         |       2       | 2010-11-14 15:50:05|
|   10010         |  21         |   1       | 2010-11-14 15:50:59|  <-- this is why i need this.
|   10011         |  21         |       2       | 2010-11-14 15:55:05|  <-- this is why i need this.

Im currently using :

$kust  = $_POST['AKuu'];
$kuni3 = $_POST['LKuu'];
$valitudtootaja   = $_POST['TNimi'];


mysql_select_db($database, $con);
$query2 = "SELECT *, SUM(punch_id) FROM punch_log WHERE user_id = '".$valitudtootaja."' AND punch_time   BETWEEN '$kust' AND '$kuni3' AND punch_id ='1' ";   
$result2 = mysql_query($query2) or die(mysql_error());
while($row = mysql_fetch_array($result2)){
   $X = $row['SUM(punch_id)'];

When using the current query im getting

Workers days at work = 6
it should be 5 but thats why i need some solution to group dates and then sum them.

Does anybody have any ideas?

I have a html table displaying data from mysql database. I can count rows properly with mysql_num_rows but is there a way to echo which row number it is. What I want to do is count the rows ordered by cities and echo row number. Thanks for any help.

Hi everyone,

Hi everyone,

I have the task of building a PHP page where users can enter or remove as many records as they like into different categories. This then makes the number of records entered unknown, and therefore it becomes more complicated.

To make this clearer, I have attached an image of what I am trying to do.

Two questions:
- Before submitting the form, how can each record entry be matched with the correct category? (maybe hidden form fields somehow?)
- What is the best way of inserting each record (and it's associated category) into a MySQL database table from a single form submit?

I want to try and keep this as simple as possible as the data will later be updated, removed etc.

I'm experiencing a brain fart and just cannot picture the best way of going about this

Any help and advice is much appreciated!

Thanks in advance.

Code: [Select]
Basic table schema example...

CATEGORY TABLE
----------------------------
| catid |    category    |
----------------------------
|  1    |  Category A  |
|  2    |  Category B  |
etc.   etc.
----------------------------

DATA ENTRY TABLE
----------------------------
dataid | catid |    data     |
--------------------------------
|  1  |   2    |  data xyz |
|  2  |   1    |  data zyx |
etc.  etc  etc.
