I cannot update the screen and therefore the records in the "excel like keyboard navigation" program

guler1

hi,

**
I get this error when I send a parameters to staff.php file with POST method in editor of datatables in "excel like keyboard navigation" application. http://e-performans.net/excelgiris/examples/extensions/keyTable8.php
**

keyTable8.php

<? php
$ k = '01';
$ t = '2020-01-05';

<?php
>
?>


Sending parameters.
ajax: {
url: "../../controllers/staff.php",
type: 'POST',
dataType: "json",
data: {
k: "<? php echo $ k;?>",
t: "<? php echo $ t;?>"
}
},

staff.php

$ k = $ _POST ['k']; $ t = $ _POST ['t']; // incoming from keytables8.php

-> where ('FatMarker', $ k, '=')
-> where ('Date', $ t, '=')

Result

Records are visible, but when the record in a cell is changed, an error "A system error has occured (more information)" occurs. - when we want to change...

---

But when I get the same error as a fixed value in staff.php, I don't get it. http://e-performans.net/excelgiris/examples/extensions/keyTable9.php

keyTable9.php

<? php
$ k = '01';
$ t = '2020-01-05';

<?php
>
```
?>


Sending parameters.
 

ajax: {
url: "../../controllers/staff.php",
type: 'POST',
dataType: "json",
data: {
k: "<? php echo $ k;?>",
t: "<? php echo $ t;?>"
}
},

staff.php
-----------------

// !!!! $ k = $ _POST ['k']; $ t = $ _POST ['t']; // incoming from keytables9.php !!!!!! not working

but,

$ k = '01'; $ t = '2020-01-05'; works?. Could I explain?

-> where ('FatMarker', $ k, '=')
-> where ('Date', $ t, '=')

Result
========
The records are visible, but when the record in a cell is changed I don't get the "A system error has occured (more information)" error, so it works fine :)

Hi,

The response from the server to your System error issue is:

Notice: Undefined index: k in /home/eperform/public_html/excelgiris/controllers/staff.php on line 36

Notice: Undefined index: t in /home/eperform/public_html/excelgiris/controllers/staff.php on line 36
{"data":[]}

Which is correct - a k and t parameter are not being sent to the server on edit. It is for the data get request by DataTables, but you don't have an ajax.data for Editor. See ajax.data for details on how to add it.
