PHP - Need Help To Calculate Volume In Php
Hi,
I have an itinerary form at http://www.happydaysremovals.com/estimate.html Customers fill this in, and it uses phpmailer-fe to email the results to myself. I use a HTML .tpl file so I can make the output email look as I want. All that is fine, but I would like a volume calculator. Next to each item on the form, the customer enters the amount of that item, usually 1 or 2. If it was say a setee, I want to define that a setee = 30 cubic feet, for example. Then I want the calculator to calculate the total cubic footage for all the variables, and include it in the html email. I know with javascript this can be done, but I was hoping for a PHP result and for it to somehow work in with phpmailer-fe, for example: </style> <script language="JavaScript"> function write_this() { var setteelarge; var setteemedium; var setteesmall; var setteelarge2; var setteemedium2; var setteesmall2; var setteelargeresult; var setteemediumresult; var setteesmallresult; var total; setteelarge = document.form1.LargeSettee.value; setteemedium = document.form1.MediumSettee.value; setteesmall = document.form1.SmallSettee.value; setteelarge2 = 45 setteemedium2 = 31 setteesmall2 = 22 setteelargeresult = (setteelarge * setteelarge2); setteemediumresult = (setteemedium * setteemedium2); setteesmallresult = (setteesmall * setteesmall2); total = (setteelargeresult+setteemediumresult+setteesmallresult) document.form1.Total_Cubic_Feet.value = total } </script> Basically, I want to be able to include the cubic feet total value to also be emailed to me in the HTML email, but preferably all in PHP. At the moment, I get everyones itinerary, but want to be automatically be able to work out the cubic footage. Thanks Similar TutorialsHey guys im stuck in a bind and need some input. What im trying to do is display a number based from community levels. ex: This user need another 2 tasks to get next level. here are the levels 1- 0-2 task new 2- 2-5 tasks beginer 3- 5-7 tasks pro 4- 7+ tasks advanced The way it works is by two different tasks. basicly i wanna know which is the higher number in the tasks either how many posts or comment and figure out based on our levels how many tasks he need to complete in order for him to reach the next level. the first query sees how many post this user has the second check how many comment he has I wanna take the highest number and that belongs to whicheber catgory, do a calculation. and have this kind of output This user is level 2 and need 1 more task to reach the next level. Like i know if he need one more that he has 4 tasks done. I know im all over the place with this one im just trying to get someone who might have an idea of my issue and point me in the right direction. Either if this is a known ?? does this procedure has a specific name anything will help me. I am wondering is it possible to calculate with an alphernumeric ID in PHP, can PHP basically make sense out of an ID like c04 ? I used such ID system for the category system because I was able to make more sense out of the c in front of the number, which is not necessarily needed. Would a SQL calculation like "$category_id + 1" work? Whereas $category_id stands for c04 and becomes a c05 after calculation. is it possible to calculate sum of the element in the array_pop . i have to get sum of 3 maximum subject with grade from student .

All appointments last 30 mins. I also have a list of times that staff are available to meet these appointment times (can be in any format, array etc.) I need to ensure the appointment times are fully covered by members of staff. E.g.

This question may sound like a MySQL question, but I think it relates more to PHP... Currently I have the following (pseudo-code) query in my PHP script...
SELECT id, col-a, col-b, col-c, usefulCount, usefulResponses, (usefulCount/usefulResposnes) as usefulPct newMedianCalculationHere FROM( SELECT DISTINCT col-a, col-b, col-c, (SELECT COUNT(xtc.id) FROM table-7 INNER JOIN table-8 ON WHERE something AND respone_yn = 1) AS usefulCount, (SELECT COUNT(xtc.id) FROM table-7 INNER JOIN table-8 ON something WHERE something) AS usefulResponses (Add Median calculation here) AS newMedianCalculationHere FROM INNER JOIN WHERE ) AS wrapper ORDER BY whatever
Now I need to calculate the median of some data and drop that in my inner query. Here is some sample code that I found online... https://www.eversql.com/how-to-calculate-median-value-in-mysql-using-a-simple-sql-query/
SET @rowindex := -1; SELECT AVG(g.grade) FROM (SELECT @rowindex:=@rowindex + 1 AS rowindex, grades.grade AS grade FROM grades ORDER BY grades.grade) AS g WHERE g.rowindex IN (FLOOR(@rowindex / 2) , CEIL(@rowindex / 2));
Because my query is in a PHP script, I'm now sure how to incorporate these lines...
SET @rowindex := -1; (SELECT @rowindex:=@rowindex + 1 AS rowindex,
Oh, if it matters, I use prepared statements in my PHP...
Thanks.
Hi, I need to calculate absent percentage but not sure how. working days from Sunday to Thursday every week so 5 working days a week. i will calculate the absent days from joining date until current date. Example if joining date is 24-3-2020 and today's date is 7-4-2020 i should get the number of absent days to 11 days since both Friday and Saturday are excluded. How to do that? here is what I have: $workingdays = $curdate - $joindate; $workingdays = $workingdays - $absent = ($counter / $workingdays) * 100; the second line i missing the number of days for (Fridays and Saturdays) that should be excluded from calculations. The third line i did calculate the actual working days ($counter) for the employee so then i can get percentage of absent days. How to exclude the weekend days from calculations?

I currently have a stored datevariable in the format: YYYY-MM-DD H:m:s ... So basically what I wish to accomplish is figuring out whenever i load the page which has stored this variable, how much time has passed. I want it to show up as for example : '10 minutes ago'.. '1 hour 25minutes ago' if it's the same day.. if its more than 1 day old it's enough to show only the number of days.....'1week 3 days ago' etc etc I have an HTML table with the following columns: - Event - Price - # of Attendees - Total - Choose One The values are populated from a database, and I am using a loop to create the Table.
