function view_report($dateval1, $dateval2, $id) {
        global $connection;

        $query_get      = "SELECT * FROM presence WHERE p_date BETWEEN {$dateval1} AND {$dateval2} ORDER BY DATE";
        $query_confirm  = mysqli_query($connection, $query_get);

        if(isset($_POST["show"])) {

            while($record = mysqli_fetch_assoc($query_confirm)) {

                $output  = "<tr>";
                $output .= "<td>" . $record["p_date"] . "</td>";
                $output .= "<td>" . $record["p_day"] . "</td>";

2e part:

       $output ="";
           while($record = mysqli_fetch_assoc($query_confirm)) {
                $output .= "<tr>";
                $output .= "<td>" . $record["p_date"] . "</td>";
                $output .= "<td>" . $record["p_day"] . "</td>";
                $output .= "<td>" . $record["timein"] . "</td>";
                $output .= "<td>" . $record["timeout"] . "</td>";
                $output .= "<td>" . "06:25:22" . "</td>";
                $output .= "<td>" . $record["p_date"] . "</td>";
                $output .= "</tr>";
                }   
            return $output;

not sure about the 1st part.
Are $dateval1 eand $dateval2 in the proper format?
how is p_date defined? date? dateTime?

Hi,

Add some error trapping to your query and see if it sheds any more light ...
$query_confirm = mysqli_query($connection, $query_get) or die(mysqli_error($connection));

Based on your previous threads, I assume your p_date still is 'date' format in database. You can try @Zagga's idea by adding the die() to show the error, but now your problem is the query. Try out
SELECT * FROM presence WHERE p_date BETWEEN '$dateval1' AND '$dateval2' ORDER BY p_date main problem should be 'DATE' is not exist in the table.

Think I mentioned before, globals bad, just pass the connection.
Also use prepared statements if using input data.
pz has the return in the loop issue solved
Good advice from Zagga wrt errors

@diafol

yes you metioned me about that and I also went through it but was having some dificulties in doing that I will post a thread for that.

@lps

the date column exist as p_date is the date column

I modified my code and placed it on the main here is the code and let me know where i am doing mistake though

Your are still using ORDER BY DATE instead of p_date. Also you can save you fetch_assoc to an array and use fetch assoc to ouput the data which will be relevantly fast than echoing every thing bit by bit when dealing with huge amount of data.

You are missing single quotes around your dates.

Gideon_1 15 Junior Poster · Answer 6 · 2015-05-20T10:26:29+00:00

You have made many mistakes of which include
1. Setting Form action to POST but using GET in PHP
2. Did not initialize mysqli connection
3. Were not sorting output by any column but instead you used a function.

Try these codes and make changes to it so it matches with your credentials

try echoing out the mysqli_num_rows($query_get)

Runs perfect

$query_get      = "SELECT * FROM presence";

and with num rows echo 10

You are still missing the single quotes around your dates.

Yah, your dates can also be problem. use

    $date1 = "{$year}-{$month}-{$startday}";
    $date2 = "{$year}-{$month}-{$endday}";

so try the sql

SELECT * FROM presence WHERE user_id = {$id} AND p_date BETWEEN {$date1} AND {$date2} ORDER BY p_date

Then echo out mysqli_num_rows
