How to generate HTML table based on group by? - php

Question

I am trying to create very simple time tracking app with only 3 values in database: description, time-spent and date and I need to group results by Date and generate HTML tables.
For example:
Today(10.07) for this date I have 3 records in database, I need to generate HTML table for this date.
Tommorow(11.07) when I create new record with new date - it creates new HTML table.
At the and I have a lot of HTML tables with specific day dates.
(HTML table for its own date).
So how to group by date and how to generate HTML tables?
The screenshot below reflects what I'm trying to achieve:
Below is my code:
function getLogs( $con ) {
$stmt = $con->prepare( "SELECT * FROM timelogsapp GROUP BY DATE ORDER BY date DESC" );
$stmt->execute();
$result = $stmt->fetchAll();
foreach( $result as $row ) {
echo '<table class="list-table">';
echo '<thead>';
echo '<span class="date">';
echo datetime();
echo '</span>';
echo '<tr>';
echo '<th>Description</th>';
echo '<th>Time</th>';
echo '<th>Date</th>';
echo '</tr>';
echo '</thead>';
echo '<tbody>';
echo '<tr>';
echo '<td>' . $row['description'] . '</td>';
echo '<td>' . $row['time'] . '</td>';
echo '<td>' . $row['date'] . '</td>';
echo '</tr>';
echo '</tbody>';
echo '</table>';
}
}

Answer 1

You can create a SQL WHERE the dates are within the wanted range. So you said you wanted to be for today, it would look like this:
UPDATE
This should create multiple queries and you can Add more to the WHERE clause, to get the custom date, I hope this gives you an idea of what you can do with.
Every record will create it's unique table, as they are inside of the foreach clause.
<?php
$today = date('d.m');
$today_query = "SELECT * FROM timelogsapp WHERE date = $today DESC";
$yesterday = date('d.m', time() - 60 * 60 * 24);
$yesterday_query = "SELECT * FROM timelogsapp WHERE date = $yesterday DESC";
$custom = "";
if (isset($_POST['date']))
{
$custom = $_POST['date'];
}
$custom_query = "SELECT * FROM timelogsapp WHERE date = $custom DESC";
$tom = new DateTime('tomorrow');
$tomorrow = $tom->format('d.m');
$tomorrow_query = "SELECT * FROM timelogsapp WHERE date = $tomorrow DESC";
function getLogs($con){
$stmt = $con->prepare("SELECT * FROM timelogsapp WHERE date = $today AND date = $yesterday AND date = $custom DESC");
$stmt->execute();
$result = $stmt->fetchAll();
foreach($result as $row) {
echo '<table class="list-table">';
echo '<thead>';
echo '<span class="date">';
echo datetime();
echo '</span>';
echo '<tr>';
echo '<th>Description</th>';
echo '<th>Time</th>';
echo '<th>Date</th>';
echo '</tr>';
echo '</thead>';
echo '<tbody>';
echo '<tr>';
echo '<td>'.$row['description'].'</td>';
echo '<td>'.$row['time'].'</td>';
echo '<td>'.$row['date'].'</td>';
echo '</tr>';
echo '</tbody>';
echo '</table>';
}
}
?>
Of course you can make that much more dynamic by playing with some PHP. But that will select all records from timelogsapp just where the dates equal to 10.07. Then display it in descending order.

I managed to achieve the result i've been looking for.
// getting all dates from database with limit
$all_dates_query = "SELECT * FROM timelogsapp GROUP BY date(date) ORDER BY date DESC LIMIT $limit OFFSET $offset";
$stmt = $con->prepare($all_dates_query);
$stmt->execute();
$all_dates = $stmt->fetchAll();
function getLogs($con, $all_dates)
{
foreach ($all_dates as $row) {
$this_date = $row['date'];
$all_dates = "SELECT * FROM timelogsapp WHERE date(date) = date('$this_date') ORDER BY date DESC"; //getting all logs for current date
$stmt = $con->prepare($all_dates);
$stmt->execute();
$result = $stmt->fetchAll();
//generating html table with logs
echo '<table class="list-table">';
echo '<thead>';
echo '<span class="date">';
echo datetime($this_date);
echo '</span>';
echo '<tr>';
echo '<th>Description</th>';
echo '<th>Time</th>';
echo '<th>Date</th>';
echo '</tr>';
echo '</thead>';
echo '<tbody>';
foreach ($result as $row) {
echo '<tr>';
echo '<td>'.$row['description'].'</td>';
echo '<td>'.$row['time'].'</td>';
echo '<td>'.date('d.m.Y H:i', strtotime($row['date'])).'</td>';
echo '</tr>';
}
echo '</tbody>';
echo '</table>';
}
}
