datasheet – Blank window when editing list item

I have a problem when I want to edit a list item.
When click on it or “…” edit item I receive white window with “x” all items of the list.

However when I want to add an item there is no issue; form is opened and can be filled.

Have you already seen this kind of issue? Thank you for your help.

symfony services – How to get $_POST which has blank parameters

I understand that as per new rules, post request in drupal should be replaced with $stack->getCurrentRequest()->request.

But I need to know what is the replacement for $_POST which does not have any parameters. Should we use $stack->getCurrentRequest()->request->get() or $stack->getCurrentRequest()->request->all()?

InfoPath Web Part sends blank value to List view WebPart

I would like to use a value (in a dropdown) from an Infopath web part (list form) to send a filter value to list view webpart. I have added a button to send data to webpart, I’ve also tried included this rule on the drop down. I feel like I’ve tried all the settings and such, but the Infopath webpart always sends “empty” value to the list view webpart. It doesn’t want to send the value in my dropdown, just send empty every time. I have send first row of data unchecked, and send data when page loads is also unchecked. Is this even possible? Or am I missing something?

graphics card – Monitors connected to on-board HMDI and VGA ports shows blank after installing Nvidia Driver | Fedora 32

I am using a desktop with 3 monitors.

2 x 21-inch Dell monitors
1 x 34-inch LG monitor

The 2 Dell monitors, one is connected to the VGA port on-board, and the second one is connected to the onboard HDMI port.

The third and the large monitor 34 inches LG is connected to the HDMI port of NVIDIA GeForce GTX 1650 SUPER.

The system was using Windows 10, but I replaced it with Fedora 32 KDE last week, also installed Nvidia driver and CUDA successfully then. It has been working well until today, but I have no idea what really happened in the system or if some system update has undergone without my knowledge, when I tried to boot up the machine today morning, all I can see only the large 32inch LG monitor connected to Nvidia graphic card is showing up. The system is showing disconnected status for the rest two Dell monitors connected on-board VGA and HDMI ports which are using Intel onboard integrated GPU.

twrp – How to replace /dev/block/bootdevice/config with a blank one?

Is there a way to sideload the empty file, or access shell with root anyhow so I can dd if zero /of it?
The phone is an old moto E4. Encrypted. OEM not unlocked. Can’t install TWRP either I don’t know how to start it in EMMC if there is a way to do so. I have no access to the google account anymore the recovery phone number belonged to my old German phone number. I just want to resurrect it for the cats for fun.

applications – when i open a new file (of java or kotlin), then why the mainActivity.xml or java is blank?

I have recently downloaded android studio and it works fine from past 2-3 days. But today, when i open a new file of java or kotlin, then although the gradle was downloaded manually, but then also the MainActivity.xml is blank and the folder also did not uploaded properly. (i mean when i click the res floder, the layout folder was missing)?
And at the APP, the android studio symbol, there was a small cross, over there. And when i run it, it says the configuration is wrong.
what should i do? pls help.

MYSQL TIMESTAMP when adding DATE_FORMAT then the output is blank, PHP conflict?

Usingthe following shortcode function, I have the code building a table by querying the DB. That all works fine. BUT when I add any type of formatting to the TimeStamp column such as DATE_FORMAT or TIME the output for that column only goes blank. No errors are in the console to look at. I am trying to extract only the time and put it in a 12 hour format instead of the typical TIMESTAMP format of date and time in the 24hr set up.

Is there a conflict with some of the PHP that causes it not to display the timestamp?

 function test2() {
        global $wpdb;
    $results = $wpdb->get_results("SELECT `name`, `partysize`, `phonenumber`, `emailaddress`, DATE_FORMAT(`Time_stamp`, '%h %i' ), `Wait`, `currentstatus` FROM mytablename m RIGHT JOIN (SELECT wdt_ID, CONCAT(ROUND(Time_to_sec(TIMEDIFF (NOW() ,`Time_stamp`))/60,0), ' Min') AS Wait FROM mytablename) as t on m.wdt_ID = t.wdt_ID WHERE Time_stamp >= date_sub(now(),interval 3 hour)  "); 
            echo "<table width='100%' border='0' style='display:inline-table'>
            <th>Party Size</th>
            <th>Phone Number</th>
            <th>Email Address</th>
            <th>Time Stamp</th>
            <th>Action</th>     ";
            echo "<tbody>";      
            foreach($results as $row){ 
                echo "<tr>";
                //echo "<td>" . $row->wdt_ID . "</td>";
                echo "<td>" . $row->name . "</td>";
                echo "<td>" . $row->partysize . "</td>";
                echo "<td>" . $row->phonenumber . "</td>";
                echo "<td>" . $row->emailaddress . "</td>";
                echo "<td>" . $row->Time_stamp . "</td>";
                echo "<td id='tdid_".$row->wdt_ID."'>" . $row->currentstatus . "</td>";
                echo "<td>" . $row->Wait . "</td>";
                echo '<td> <a href="javascript:void(0)" class="button seated-btn" onclick="seatclick('.$row->wdt_ID.')" data-id="'.$row->wdt_ID.'"></a></td>';

    add_shortcode('test2', 'test2'); – Apple Mail adds blank rows to CSV file

I’m having an odd problem. I’ve recently decided to try Apple Mail as my default mail platform. Everything is being great until a coworker noticed that the .csv files I send come out with blank rows in between.

  • This is the original file (randomly generated for this example).
    enter image description here

  • This is the file sent by another mail platform (Outlook Desktop for example),
    and opened with TextEdit app or Notepad in windows.
    enter image description here

  • This is the file sent with Apple mail on Mac, and opened with TextEdit app or Notepad in windows.
    enter image description here

I’ve been looking into resources, and apparently there is some different with formats using such as CR in Mac, and CRLF in windows but I still can’t answer this questions.

  1. Why does this happen?
  2. Is there a setting I can correct in Excel?
  3. Is there a setting I can correct in the Mail app?
  4. Will this happen with other types of files?

Any help on this is appreciated!

Note: File also has blank rows when opening in Excel, or Numbers after it was sent through Apple Mail. Before this, the file looks normal in all apps mentioned above.

How do I display data from cells, but skip over the blank cells?

I have a list of scores, and I need to display them concisely. How do I read a long row of cells only some of which have scores in them, and print those scores out?


I tried using a combination of arrayformula and if’s, but failed pretty terribly : ]
