sql queries in php
Question
I run a small helpdesk and I have a requirement to produce a ticket report every month to my line manager.
I am looking to upgrade the way in which we produce this report because at present, I run the below query I wrote manually every month by using Navicat:
SELECT
updates.incidentid AS `Incident ID`,
updates.bodytext AS `Call Status`,
updates.duration AS `Total Minutes`,
software.`name` AS 'Support Type',
incidents.title AS Description,
contacts.forenames AS `First Name`,
contacts.surname AS `Last Name`,
FROM_UNIXTIME(incidents.opened, '%d.%m.%Y') AS `Date Logged`,
sites.`name`,
users.realname
FROM
updates
INNER JOIN incidents ON updates.incidentid = incidents.id
JOIN contacts ON incidents.contact = contacts.id
INNER JOIN sites ON sites.id = contacts.siteid
INNER JOIN users ON incidents.`owner` = users.id
INNER JOIN software ON incidents.softwareid = software.id
WHERE
updates.bodytext = 'Incident Closed'
AND FROM_UNIXTIME(incidents.opened, '%m') = '07'
AND FROM_UNIXTIME(incidents.opened, '%Y') = '2016'
ORDER BY contacts.siteid ASC
I would like to put this all in a very simple webpage allowing the user select the month and year and then offer them a HTML formatted download.
Would I be best placed to put this in PHP or can I create it in HTML? Please be kind, I am a total newbie and my thought process is a little off.
Many thanks for your time and patience!

I'll show you the basic : first, one HTML file where the user enters month and year as numbers (notice the call to "report.php") :
<html>
<body>
<form method="post" action="report.php">
Enter month (1..12) <input type="text" name="month"/>
<br/>
Enter year (four digits) <input type="text" name="year"/>
<br/>
<input type="submit" value="Display report"/>
</form>
</body>
</html>
Now the PHP file "report.php" (notice how month and year are captured at the beginning and stored in variables $month and $year ) :
<?php
$month = $_POST["month"]; // PARAMETERS FROM
$year = $_POST["year"]; // THE HTML FILE.
$cnx = mysqli_connect( "localhost","user","password","databasename");
$data = mysqli_query( $cnx,"YOUR BIG SELECT HERE" ) or die( mysqli_error( $cnx ) );
echo "<table>" .
" <tr>" .
" <td>Incident id</td>" .
" <td>Call status</td>" .
" <td>Description</td>" .
" <td>Date logged</td>" .
" <td>Site name</td>" .
" <td>User</td>" .
" </tr>";
while ( $row = mysqli_fetch_array( $data ) ) // LOOP TO DISPLAY DATA.
echo "<tr>" .
" <td>{$row["IncidentID"]}</td>" .
" <td>{$row["CallStatus"]}</td>" .
" <td>{$row["Description"]}</td>" .
" <td>{$row["DateLogged"]}</td>" .
" <td>{$row["name"]}</td>" .
" <td>{$row["realname"]}</td>" .
"</tr>";
echo "</table>"; // TABLE END.
?>
You have to replace the text "YOUR BIG SELECT HERE" by your big query. This is how you insert variables $month and $year in the query :
SELECT
updates.incidentid AS `Incident ID`,
updates.bodytext AS `Call Status`,
updates.duration AS `Total Minutes`,
software.`name` AS 'Support Type',
incidents.title AS Description,
contacts.forenames AS `First Name`,
contacts.surname AS `Last Name`,
FROM_UNIXTIME(incidents.opened, '%d.%m.%Y') AS `Date Logged`,
sites.`name`,
users.realname
FROM
updates
INNER JOIN incidents ON updates.incidentid = incidents.id
JOIN contacts ON incidents.contact = contacts.id
INNER JOIN sites ON sites.id = contacts.siteid
INNER JOIN users ON incidents.`owner` = users.id
INNER JOIN software ON incidents.softwareid = software.id
WHERE
updates.bodytext = 'Incident Closed'
AND FROM_UNIXTIME(incidents.opened, '%m') = '$month' ◄■■■■
AND FROM_UNIXTIME(incidents.opened, '%Y') = '$year' ◄■■■■
ORDER BY contacts.siteid ASC
Copy-paste previous codes in two files named "report.html" and "report.php", then open "report.html" in your browser.
There are many things to improve, for example, with jQuery you can improve how the user enters month and year, but that's for another question.

您可以使用HTML，可能使用javascript来访问选定的月份和年份值并将其插入查询模板的字符串中，以生成SQL查询，但是如果要通过服务器端运行查询，则可以不妨使用PHP或其他脚本语言。

Mashymoo, if you use Navicat, you could use Navicat Report Builder . Hope this helps. Managers love reports!

Best way to do it in my opinion
Place all requests in query (ie sql table called report_queries). Allow users to request data every month, day or week as they need. Use Cron jobs to check every 2 hours or so for not yet generated reports. Of course if there any reports that is still not generated, generate only few of them, 10 in example to prevent server crash due large memory usage, and inform user about generated report either via notification in your page, or something like push notifications (Chrome, Android, iOS etc). I personally am using FPDF library that is PHP PDF generation library. It allows using html to make pdf.
Here is a diagram to help you visualize the idea:
I numbered the steps :
- User request for report, here you check for same records etc.
- Cron job takes place, and calls script.
- Script checks for requests that still have not been generated and generates those
- Script update report status and continues.
- Script provides report file and that it.

Yopu can use Navicat Report Builder included in standard Navicat for Windows to generate a report.
And you don't have to run the generator manually every month, We have a feature named Schedule , you can add the report generation task to a schedule and the report will be generated regularly.
Feel you to contact us if you have any problem.
