Answer 1

Try this:

$result = mysqli_query($conn, "SELECT * FROM $dbname.statusinfo WHERE soid = '$userinput1' AND date_column <> '0000-00-00' ") or die(mysqli_error($conn));

Although, with mysql you may even be able to do this:

$result = mysqli_query($conn, "SELECT * FROM $dbname.statusinfo WHERE soid = '$userinput1' AND date_column > '0000-00-00' ") or die(mysqli_error($conn));

Hope this helps

EDIT

I can see what you want now that you amended the question :) Unfortunately I do not know of a way to what you want using SQL (someone may).

You are outputting the column headings and so not outputting a particular column would cause them to appear in the wrong columns so you will just have to output nothing where time is 0000-00-00

This is how I would do it in PHP though. (and if I have missed your point again I may shoot myself :))

connect_errno) {
        printf("Connect failed: %s\n", $conn->connect_error);
        exit();
    }

    $result = mysqli_query($conn, "SELECT * FROM $dbname.statusinfo WHERE soid = '$userinput1'  ") or die(mysqli_error($conn));

    $arrayHeadings = array(
        "dept"                  => "Department", 
        "samplerecived"         => "Sample Recived",
        "molbioextraction"      => "Mol-Bio Extraction",
        "molbioextractionqc"    => "Extraction QC",
        "libraryprep"           => "Library Prep",
        "libraryqc"             => "Library QC",
        "sequencing"            => "Sequencing",
        "datacheck"             => "Data Check",
        "resequencing"          => "RE Sequencing",
        "qccheck"               => "QC Check",
        "analysisstarted"       => "Analysis Started",
        "analysiscompleted"     => "Analysis Completed",
        "report"                => "Report",
        "outbound"              => "Outbound",
    );

?>


 $name): ?>
             $name): ?>
                

EDIT

The table headings are not output if the field contains 0000-00-00. This relies on only one element being output at a time.

connect_errno) {
        printf("Connect failed: %s\n", $conn->connect_error);
        exit();
    }

    $result = mysqli_query($conn, "SELECT * FROM $dbname.statusinfo WHERE soid = '$userinput1'  ") or die(mysqli_error($conn));

    $arrayHeadings = array(
        "dept"                  => "Department", 
        "samplerecived"         => "Sample Recived",
        "molbioextraction"      => "Mol-Bio Extraction",
        "molbioextractionqc"    => "Extraction QC",
        "libraryprep"           => "Library Prep",
        "libraryqc"             => "Library QC",
        "sequencing"            => "Sequencing",
        "datacheck"             => "Data Check",
        "resequencing"          => "RE Sequencing",
        "qccheck"               => "QC Check",
        "analysisstarted"       => "Analysis Started",
        "analysiscompleted"     => "Analysis Completed",
        "report"                => "Report",
        "outbound"              => "Outbound",
    );
