[英]The first html row is not being displayed
因此,假設我的數據庫中有10行。 但是,在mysql查詢后,html表中僅顯示9行。 我需要數據庫中的每一行都顯示在html表中。
我希望有人能指出我正確的方向。 如果需要提供更多詳細信息,我會在這里。
這是我的代碼:
<?php
$sqlQuery = "SELECT * FROM periods";
$result = mysqli_query($conn, $sqlQuery);
$resultCheck = mysqli_num_rows($result);
if ($resultCheck > 0) {
while ($row = mysqli_fetch_assoc($result)) {
$id = $row['id'];
$out = $row['fell_out'];
$in = $row['fell_in'];
$sum = $row['sum'];
$nextEstimate = $row['next_estimate'];
$nextEstimateDays = $row['next_estimate_days'];
$notes = $row['notes'];
$sqlQueryLastDate = "SELECT * FROM (select * from periods WHERE id < $id ORDER BY id DESC LIMIT 1) AS x ORDER BY id LIMIT 1";
$resultLastDate = mysqli_query($conn, $sqlQueryLastDate);
$resultCheckLastDate = mysqli_num_rows($resultLastDate);
if ($resultCheckLastDate > 0) {
while ($rowLastDate = mysqli_fetch_assoc($resultLastDate)) {
$lastInDate = $rowLastDate['fell_in'];
$sqlQueryCurrentDate = "SELECT * FROM (select * from periods WHERE id = $id ORDER BY id DESC LIMIT 1) AS x ORDER BY id LIMIT 1";
$resultCurrentDate = mysqli_query($conn, $sqlQueryCurrentDate);
$resultCheckCurrentDate = mysqli_num_rows($resultCurrentDate);
if ($resultCheckCurrentDate > 0) {
while ($rowCurrentDate = mysqli_fetch_assoc($resultCurrentDate)) {
$currentOutDate = $rowCurrentDate['fell_out'];
$lastIn = new DateTime($lastInDate);
$currentOut = new DateTime($currentOutDate);
$intervalLastCurrent = $lastIn->diff($currentOut);
$elapsedLastCurrent = $intervalLastCurrent->format('%a days %h hours');
/*Why? Php is erasing everything after adding the above variable to the table...Entire first row gets erased!*/
echo "
<tr>
<td>".$id."</td>
<td class='test'>".$elapsedLastCurrent."</td>
<td class='dateOutResult'>".$out."</td>
<td class='dateInResult'>".$in."</td>
<td class='sumHours'>".$sum."</td>
<td class='nextEstimate'>".$nextEstimate." (".$nextEstimateDays.")</td>
<td class='notes'>".$notes."</td>
</tr>";
} /*$sqlQueryCurrentDate*/
}
} /*$sqlQueryLastDate*/
}
} /*$sqlQuery*/
}
?>

我真的是mysql / php的新手,所以我不明白我在做什么錯。 嵌套查詢可能不是最好的使用方法,但是我仍在學習中,任何輸入都會受到贊賞。
這是因為您的查詢是//從ID <$ id的句點中選擇* * ORDER BY ID DESC LIMIT 1; 您的第一個$ id將始終等於id。
