No, No, No! For the last time (I'll type it slowly), NOT the order id You need the id of the individual order detail record name="quantity[$result->id]"
-
The time-limit for editing the post will have expired by now. Post your current code
-
do you now have name="quantity[$result->id]" and same for the other order detail fields?
-
You need to be using tbl_orderdetail.id as the indexes for the field names
-
Add a hidden field to your form containing the id of whatever they are commenting on. Save this id, comment and user_id to a comments table. The id will allow you to relate the comment to the original.
-
NOT the order_id. That would give the fields for every detail record the same id. You want the id from the order detail records

SELECT statement, Multiple WHERE, with requirements
Barand replied to BuildMyWeb's topic in MySQL Help
Separate tables will be a PIA when you need to query for results across regions. EG How many submissions have we had in the last three months? -
At the moment you have name='productname[]'. I am suggesting you change that to name='productname[$det_id]' where $det_id is the id of the order detail record. Do this for all fields to tie them to the same record. That will be the key of the POSTed data foreach ($_POST['quantity'] as $ord_det_id => $quantity) {
-
This will do it using CSS $sql = "SELECT timeslot , client , TIMESTAMPDIFF(HOUR, timeslot, NOW()) as elapsed FROM timeslots"; $res = $db->query($sql); $rows = ''; while (list($ts, $cl, $el) = $res->fetch_row()) { $class = $el >= 20 ? 'class="blink"' : ''; $rows .= "<tr><td>$cl</td><td $class>$ts</td></tr>\n"; } ?> <html> <head> <title>Example Flashing</title> <style type='text/css'> /* The animation code */ @keyframes flash { from {background-color: red;} to {background-color: white;} } /* The element to apply the animation to */ td.blink { width: 100px; height: 100px; background-color: white; animation: flash 1s infinite; } </style> </head> <body> <table border="1"> <tr><th>Client</th><th>Time</th></tr> <?=$rows?> </table> </body> </html>

Use the order detail record ids as the array indexes for the field names E.G. name="quantity[$det_id]" name="productname[$det_id]" Then you can use those ids to update the associated detail records foreach ($_POST['quantity'] as $ord_det_id => $quantity) { $productname = $_POST['productname'][$ord_det_id]; ... $sql = "UPDATE tbl_orderdetail SET productname='$productname', quantity=$quantity, ... WHERE order_detail_id = $ord_det_id"; }

Post variables from a while loop from a second table in form
Barand replied to jgreen's topic in PHP Coding Help
You still only need the id, then when the form is posted INSERT INTO table2 (book_id, name, cover, pageno) SELECT book_id, name, cover, pageno FROM table1 WHERE book_id = $posted_id -
You could SELECT ... , Created_date , TIMESTAMPDIFF(HOUR, Created_Date, NOW() ) as elapsed FROM ... then apply flashing when odbc_result($result, "elapsed") >= 20

Post variables from a while loop from a second table in form
Barand replied to jgreen's topic in PHP Coding Help
A database should hold data in a single place and the only things that are replicated in other tables are key values. So the only item you transfer to table2 should be the book_id. You get the book name etc by referencing the book table via the id value. -
QOC, You seem to be misinterpreting the single quote restriction. This applies when the entire string is in single quotes. Single quotes inside a double quoted string do not turn off variable parsing. $myvar = 'abc'; echo "The value in \$myvar is '$myvar' "; //--> The value in $myvar is 'abc'

Post variables from a while loop from a second table in form
Barand replied to jgreen's topic in PHP Coding Help
So you want to transfer three columns of data from table1 to table 2? Why do you have form involved? They are hidden fields so the user cannot see or edit them? -

Barand replied to jgreen's topic in PHP Coding Help
Forget about your "solution" for now - what is it you want to achieve? -
What's with all the @variables? SELECT item_id , SUM(positive) as totpos , SUM(neutral) as totneu , SUM(negative) as totneg , COUNT(*) as tot , SUM(positive + neutral - negative)/COUNT(*)*100 as pcent FROM user_feedback GROUP BY item_id;

You don't show your call to the function. Is this code in a file of its own?

I used MySqli because that's what I have, but it should be easily converted for sqlsrv.

"</td></tr>\n"; } $currq = $row['question']; // store new question $qarray = $newArray; // reset the array } $qarray[$row['name']] = $row['answer']; // store the answer by name } // output the stored array for the final question $tableData .= "<tr><td>$currq</td><td>"; $tableData .= join('</td><td>', $qarray) .

The connection is to the server so if the databases are on the same server then a single connection is sufficient. You can, if you want, mix databases in a single query if on the same server SELECT ... FROM database1.tableA as a INNER JOIN database2.tableB as b

Also note the the use of session_register() was replaced by $_SESSION in December 2001.

Of course it's for the select box - that's what you said your problem was
