PHP - Count The Number Of Multiple Showing Variable In A Column

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

I need help with a count query and displaying it.  Right now have the following query

$query = "SELECT COUNT(*) as num1 FROM spoiler WHERE id='$id";
$total_trophies = mysql_fetch_array(mysql_query($query));
$total_trophies = $total_trophies[num1];

So I have another query that pulls how many trophies there are.  That way I can do the following


?  echo $total_trophies; echo 'of'; echo $row[trophy_count];  ?>

But the problem is sometimes in my database I could have mulitple entrys per trophy.  For Trophy 1 I might have only one record so It counts it correctly for trophy 2 I could have 3 records so It counts each one of those records when I only one to count it once for that trophy

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 />';}
}
?>

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 all,

I am trying to use the Mysql COUNT function to count the number of records in a database where the manufacturer is the same and then generate a list of all manufacturers along with a number of associated records next to their name.

I have got the script below to show the manufacturer in a fetch array but I can not get the number next to the manufacturer to work.

A push in the right direction would be appreciated thanks.


<?php 
include("cxn.php");

$query = "SELECT manufacturer FROM sales"; 
$result = mysqli_query($cxn,$query) or die(mysqli_error());
 
?>
<select name="manufacturer" id="manufacturer">
<option value="" selected="selected">Select a Manufacturer..</option>";
<?php 
while($row = mysqli_fetch_array($result)){
$query1 = "SELECT manufacturer COUNT(*) FROM sales WHERE manufacturer='$row[manufacturer]'";  // TRYING TO COUNT THE ROWS HERE
$result1 = mysqli_query($cxn,$query1) or die (mysqli_error());

while($row1 = mysqli_fetch_array($result1)){
echo "<option value=\"202\">".$row['manufacturer'] ."[". $row1['COUNT(manufacturer)']."]</option>"; // SHOW NUMBER HERE
}
}
?>

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.

Hi Everyone,

I am working on implementing a blog comment system using the query below to display comments. My question is what is the best way to do a row count for the id column with this query or do I need to do a second db query to accomplish this? The purpose of this is to echo out the number of comments for that post, before displaying them.

Any help is appreciated.

Thanks in advance,

kaiman

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.

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(); 
                } 
            }
