PHP - Problem Counting Average Row For Each Day
Hi,
I'm trying to get out the average of records stored in a mysql table This is the code im using right now Code: [Select] mysql_query("SELECT DATE(dato) , COUNT( dato ) AS counted FROM dekodere GROUP BY date(dato)", $link); $ave = mysql_num_rows($ave); This is getting out the average, but i need to exclude weekends because there is not stored anything during the weekend so it's making the average go off.. any tips? Similar TutorialsHi.. I have problem in getting the DemandedQty that was input. Only in the Demanded Qty of P28 items was read. For example I input 21 in Demanded Qty of P28 and then It alerts 21, but when I input 2 in Demanded Qty of P30 the alert was 21. It means only the P28 Demanded Qty was get. here is my code: <?php error_reporting(0); date_default_timezone_set("Asia/Singapore"); //set the time zone $con = mysql_connect('localhost', 'root',''); if (!$con) { echo 'failed'; die(); } mysql_select_db("mes", $con); ?> <html> <title>Stock Requisition</title> <head> <link rel="stylesheet" type="text/css" href="kanban.css"> <script type="text/javascript"> function showSum(element) { var clickElement = element.value; var click_id = element.id; var Table = document.getElementById('list'); var rows = Table.rows; var strSelect = document.getElementById(click_id).value; alert(strSelect); // i tried to alert to check if he gets the correct value, but I found that only the Demanded Qty of P28 was read. And when I try to input on another Demanded Qty like in P30 the alert was blank. for (var i = 0; i < rows.length; i++) { var row = rows[i]; if (row.id.substr(0,3) == strSelect) { } } } </script> </head> <body> <form name="stock_requisition" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> <div> <table id="list"> <thead> <th>Items</th> <th>Sub Items</th> <th>Item Code</th> <th>Demanded Qty</th> <th>UoM</th> <th>Class</th> <th>Description</th> <th>BIN Location</th> </thead> <?php $DemandedQty = $_POST['DemandedQty']; $sql = "SELECT DISTINCT Items FROM bom_subitems ORDER BY Items"; $res_bom = mysql_query($sql, $con); $rowCounter = 1; while($row = mysql_fetch_assoc($res_bom)){ $Items = $row['Items']; $Items_ = substr($Items, 12, 3); echo "<tr> <td style='border: none;font-weight: bold;'> <input type='name' value='$Items_' name='Items_[]' id='Items_[$rowCounter]' readonly = 'readonly' style = 'border:none;width:auto;font-family: Arial, Helvetica, sans-serif;font-size: 1em;'></td> <td style='border:none;'> </td> <td style='border:none;'> </td> <td style='border: none;'><center><input type='text' style='text-align: right;' name='DemandedQty[]' id='DemandedQty' value='' size='12' onkeyup ='showSum(this);'></center></td> </tr>"; $sql = "SELECT Items, SubItems, ItemCode, UoM, Class, Description, BINLocation, Quantity FROM bom_subitems WHERE Items = '$Items' ORDER BY Items"or die(mysql_error()); $res_sub = mysql_query($sql, $con); $rowCounter = 1; while($row_sub = mysql_fetch_assoc($res_sub)){ $Items = $row_sub['Items']; //$Items_ = substr($Items, 12, 3); $SubItems = $row_sub['SubItems']; $ItemCode = $row_sub['ItemCode']; $UoM = $row_sub['UoM']; $Class = $row_sub['Class']; $Description = $row_sub['Description']; $BINLocation = $row_sub['BINLocation']; $Quantity = $row_sub['Quantity']; echo "<input type='hidden' name='Quantity' id='Quantity' value='$Quantity'>"; echo "<tr> <td style='border: none;'> <input type='hidden' value='$Items' id='Items[$rowCounter]' name='Items[]'></td> <td style='border: none;'> <input type='text' name='SubItems[]' value='$SubItems' id='SubItems' readonly='readonly' style='border:none; width:auto;font-family: Arial, Helvetica, sans-serif;font-size: 1em;'></td> <td style='border: none;'> <input type='text' name='ItemCode[]' value='$ItemCode' id='ItemCode' readonly='readonly' style='border:none; width:auto;font-family: Arial, Helvetica, sans-serif;font-size: 1em;'></td> <td style='border: none;'><center><input type='text' name='SubQty[]' id='SubQty[$rowCounter]' value='' size='12' style='border:none;text-align: right;'></center></td> <td style='border: none;' size='3'> <input type='text' name='UoM[]' value='$UoM' id='UoM' readonly='readonly' style='border:none; width:auto;font-family: Arial, Helvetica, sans-serif;font-size: 1em;' size='3'></td> <td style='border: none;'> <input type='text' name='Class[]' value='$Class' id='Class' readonly='readonly' style='border:none; width:auto;font-family: Arial, Helvetica, sans-serif;font-size: 1em;'></td> <td style='border: none;'> <input type='text' name='Description[]' value='$Description' id='Description' readonly='readonly' style='border:none; width:auto;font-family: Arial, Helvetica, sans-serif;font-size: 1em;' size= '30'></td> <td style='border: none;'> <input type='text' name='BINLocation[]' value='$BINLocation' id='BINLocation' readonly='readonly' style='border:none; width:auto;font-family: Arial, Helvetica, sans-serif;font-size: 1em;'></td> </tr>"; $rowCounter = $rowCounter + 1; } $rowCounter = $rowCounter + 1; } ?> </table> </div> </form> </body> </html> Thank you so much

I can't remember the math to do this, but I use MySQL to calculate an average: 5 = 100% 0 = 0% I want to make a bar that shows an average (like a bar graph) so lets say I get 2.5 as one of my returned results, that means the bar should only be 50% long of the maximum width. Using calculations, how can I get the number 50 (the max width is 100% of a table cell)? Hi. Im trying to make a PHP code that will find the average number. What I want is, a lot of input fields where you can write a number in. Then my code should take these numbers and divide them with the amount of input fields that has been written in. So that some fields you don't have to write a number, and the code will still give you a correct average. My code so far: Code: [Select] <?php if (isset($_POST['calc'])) { $m=$_POST['mat']; $e=$_POST['da']; $s=$_POST['eng']; $f=$_POST['fys']; $h=$_POST['bio']; $p=$_POST['geo']; $ave=($m+$e+$s+$f+$h+$p)/; } ?> <a href="" onclick="return hs.htmlExpand(this, { headingText: 'Beregn dit Gennemsnit:' })"> <b>Beregn dit Gennemsnit: <?php echo $ave;?></b><br></br> </a> <div class="highslide-maincontent"> <form id="gennemsnit" name="form1" method="post" action=""> Matematik<input name="math" type="text" id="mat" size="3" maxlength="4" /><br /> Dansk<input name="eng" type="text" id="da" size="3" maxlength="4" /><br /> Engelsk<input name="sci" type="text" id="eng" size="3" maxlength="4" /><br /> Fysik<input name="fil" type="text" id="fys" size="3" maxlength="4" /><br /> Biologi<input name="he" type="text" id="bio" size="3" maxlength="4" /><br /> Geografi<input name="pe" type="text" id="geo" size="3" maxlength="4" /></td><br /> <input name="calc" type="submit" id="calc" value="Beregn"/><br /><br /> </form> What I need is the code of how to divide with the amount of input fields that has been written in. thanks for any help If you had a function that calculated the average of a fixed quantity of numbers, what type of scope issues would you anticipate? hi all! i have 2 tables: PRODUCTS id_prod, id_cat, date, prod_name CATEGORIES id_cat, cat_name My goal is obtain the average (day and month) of all products inserted by users in this format: category Hardwa avg daily 20, month 100 category Components: avg daily 2, month 15 and so on. PS: the 'date' field is unix timestamp (int 10). Can you help me? Hi,
I have a blog which records the amount of views on each article. I now want to be able to work out the average number of views per hour.
How can I work out the number of hours passed from a datetime format?
From there I can just do views divided by hours passed.
Thanks in advance!
Nice forum here. I know nothing about PHP and need some help. Here is the deal. Members on a forum will be rating products. There will be 4 (this number could change) fields where they will select a number from a drop down menu to rate different characteristics of the product. I need to average those numbers for the overall rating. The code that outputs the individual numbers selected looks like this: {$data['record']['field_14']} 14 being one of the fields, and 15, etc. So what I need is code that takes multiple fields and outputs the average number. I appreciate any help! And please keep in mind I am not familiar with PHP coding, so if you could be as detailed as possible I would appreciate it. Thanks! Hi, Firstly, these are my tables: CLASS class_id class_name 1 Donkeys 2 Monkeys 4 Classic 9 Humans COURSES class_id courses_number 9 6 9 2 1 3 2 2 I would like to print average course_number for each class_name. So for class_name Donkeys would have average course_number 3. And for clasS_name Humans, average course_number is 4. Do you get my point? Could someone please advise the best way to determine the average of a DATE field in a SELECT query?
I manage to display data using below query that will show value for each month. How to calculate average value starting july onwards(based on user selection).
Let say the value for element 'A' are Jul=80, Aug= 80, Sep=90. If user select Aug then the average is 80 and if user select Sep then the average is 83.
Query:
$sql2 = "Select element, SUM(CASE WHEN Month = 'Jan' THEN total ELSE 0 END ) AS Jan, SUM(CASE WHEN Month = 'Feb' THEN total ELSE 0 END ) AS Feb, SUM(CASE WHEN Month = 'Mac' THEN total ELSE 0 END ) AS Mac, SUM(CASE WHEN Month = 'Apr' THEN total ELSE 0 END ) AS Apr, SUM(CASE WHEN Month = 'May' THEN total ELSE 0 END ) AS May, SUM(CASE WHEN Month = 'Jun' THEN total ELSE 0 END ) AS Jun, SUM(CASE WHEN Month = 'Jul' THEN total ELSE 0 END ) AS Jul, SUM(CASE WHEN Month = 'Aug' THEN total ELSE 0 END ) AS Aug, SUM(CASE WHEN Month = 'Sep' THEN total ELSE 0 END ) AS Sep, SUM(CASE WHEN Month = 'Oct' THEN total ELSE 0 END ) AS Oct, SUM(CASE WHEN Month = 'Nov' THEN total ELSE 0 END ) AS Nov, SUM(CASE WHEN Month = 'Dec' THEN total ELSE 0 END ) AS Dis FROM tbl_ma GROUP BY element"; $rs2 = mysql_query($sql2); $getRec2 = mysql_fetch_assoc($rs2);Below is how print the data:
<?php
while ($row = mysql_fetch_assoc($rs2)) {
?>
<tr>
<td style="color:black;background-color:#f5efef"><div align="left"><?php echo $row['element']; ?></div></td>
<?php if( $year != '2014' ){ ?>
<?php if( 1 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Jan']; ?></div></td><?php endif; ?>
<?php if( 2 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Feb']; ?></div></td><?php endif; ?>
<?php if( 3 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Mac']; ?></div></td><?php endif; ?>
<?php if( 4 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Apr']; ?></div></td><?php endif; ?>
<?php if( 5 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['May']; ?></div></td><?php endif; ?>
<?php if( 6 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Jun']; ?></div></td><?php endif; ?>
<?php } ?>
<?php if( 7 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Jul']; ?></div></td><?php endif; ?>
<?php if( 8 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Aug']; ?></div></td><?php endif; ?>
<?php if( 9 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Sep']; ?></div></td><?php endif; ?>
<?php if( 10 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Oct']; ?></div></td><?php endif; ?>
<?php if( 11 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Nov']; ?></div></td><?php endif; ?>
<?php if( 12 <= $monthID ): ?><td><div align="center" style="color:black"><?php echo $row['Dis']; ?></div></td><?php endif; ?>
<td><div align="center" style="color:black"><?php //echo average; ?></div></td>

I have a table of restaurant menu items called menu_items. This table has a float row(3,2) called price. I have a query that looks like this: $query = mysql_query("SELECT * FROM menu_items WHERE restaurant = '".$restaurantid."'"); How would I find the average of the price row from that query? Basically I want to find the average item price for a restaurants menu. I have a "Users" table. I would like to find out the average users sign up in total. This table has a "joined date" column so I can track how many users sign up in a single day. For e.g. August 16 - 10 users August 17 - 20 users Auguest 18 - 30 users The total average of user sign ups would be 20 users based on the above results. So I am wondering how can I create this function? This is my starting query.
$get_users = $db->prepare("SELECT user_id FROM users");
$get_users->execute();
$result_users = $get_users->fetchAll(PDO::FETCH_ASSOC);
if(count($result_users) > 0) {
foreach($result_users as $row) {
$user_id = $row['user_id'];
}
}
Hello, I'm trying to calculate the square root of X values in an array minus the average of the array, but the first half of the values are negative, so I'm using the abs(); function to change them to positives first, but I'm still getting "NAN" as the result for the negative values that 'should' be positive. $x = array(7,3,4,6,4,2,7); $sqrt = true; $x = sort($x); $mean = 4.71; // average $XminA = array(); foreach($x as $val) { ($sqrt == true) ? $XminA[] = round(sqrt(abs($val) - $mean),2) : $XminA[] = round($val - $mean,2); } echo "<pre>"; print_r($XminA); echo "</pre>"; and my result is... Quote [XminA] => Array ( => NAN [1] => NAN [2] => NAN [3] => NAN [4] => 1.14 [5] => 1.51 [6] => 1.51 ) Not sure what I'm doing wrong, any help is appreciated. Thank you! Kind Regards, Ace EDIT: stupid mistake, need it to the power of 2 not square root. Using the wrong function sorry: ($sqrt == true) ? $XminA[] = round(pow((abs($val) - $mean),2) : $XminA[] = round($val - $mean,2); // pow() not sqrt() Quote [XminA] => Array ( => 7.34 [1] => 2.92 [2] => 0.5 [3] => 0.5 [4] => 1.66 [5] => 5.24 [6] => 5.24 ) I have a table in my database named order, and i want to count the quantity sold. i have the basic query already setup like: Code: [Select] $sql = "SELECT SQL_CALC_FOUND_ROWS deal.id, deal.title, deal.min_qty, deal.start_date, deal.end_date, deal.status, deal.secondary, count(o.id) as orders_cnt FROM deals as deal LEFT JOIN orders as o on o.d_id = deal.id WHERE start_date >= '".$beg."' AND start_date <= '".$end."' GROUP BY o.d_id, deal.id ORDER BY start_date LIMIT ".AwsPager::getCurrentIndex().", ".AwsPager::getLimit(); Which would theoretically work, but in the orders table, there is a column named quantity, and its those numbers that i need to add together and store in the array as orders_cnt.. any clue how i can do that? Hi im trying to make it so the time says how many hows left, not how many hours past. i have the right idea but it shows a negative number under "$time" $hours = number_format(($diffrence / 60 / 60)); $time = number_format(($hours - 24)); Hello I have a table that inserts a new row with data when a member views a page. I wish to count all the rows for each member, and then be able to show what the cuurent members "position" is eg. what members has the highest row count. Example. counting the rows for member_A returns 1000 rows, the number of rows for member_B returns 1500 rows. How can I display for member_A that he is in "second" place? Hiya peeps, I have a mysql database with a record of all the images a customer uploads on my site, these images are displayed on there account. I can get this to work but the problem I'm facing is I need a minimum of 5 images displayed so if they only upload 2 images for instance I need to detect that and add my "No Image Uploaded" image. But if they have uploaded 5 or more I need to just let them be displayed without adding the "No Image Uploaded" picture. Does anyone have any ideas as I'm very stuck! Many thanks James. I know how to count the files: <?php $dir = $_SERVER[DOCUMENT_ROOT]."/api/sigs/cache/".$i[id]."/"; $files = scandir($dir); $result = count($files); printf("$result Signatures Generated"); ?> But i'm trying to make it so it only counts the files that were modified recently (That Day). I have a page that displays a list of retail locations (est. 100-150 locations). I have my layout setup to fit 3 columns side by side. Ex: <div class="col"></div> <div class="col"></div> <div class="col"></div> .. with the "col" class having a specific width and float: left. Basically, I want to print out the locations in the column and when a column reaches a certain number of locations, it closes that div and starts a new one and continues printing the rest of the locations. How would I go about making sure that once a column has reached a certain number of locations, it closes the div and starts the new one? |
