【问题描述】：
目前我已经创建了一个系统，该系统可以对从 SQL 数据库中获取并显示在 dashboard_engineer.php 的数据行列表执行多个删除操作。每个数据行都包含一个删除按钮。每行还有一个复选框，使用户能够删除选定的数据行。在数据行的底部，有一个按钮可以删除所有选中的数据行。
我的问题是多次删除，比如说，如果我选择两个数据行（id 4 和 5），它只会删除一个 ID。
下面是我的代码
dashboard_engineer2.php
<?php
if(isset($_REQUEST['from'], $_REQUEST['to'], $_REQUEST['team'])){
$from = $_REQUEST['from'];
$to = $_REQUEST['to'];
$team = $_REQUEST['team'];
$result = '';
$query = "SELECT * FROM ot_report LEFT JOIN ot_users ON ot_report.badgeid = ot_users.badgeid
WHERE ot_report.status = 'yes' AND ot_users.team_id = :team AND report_date BETWEEN :from
AND :to ORDER BY ot_report.report_id DESC";
$sql = $conn->prepare($query, array(PDO::ATTR_CURSOR => PDO::CURSOR_SCROLL));
$sql->bindParam(':team', $team);
$sql->bindParam(':from', $from);
$sql->bindParam(':to', $to,);
$sql -> execute();
if($sql->rowCount() > 0){
echo'
<table class = "table-bordered" width = "100%">
<thead>
<tr>
<th width = "10%"><input type="checkbox" id="checkAl"> All</th>
<th width = "3%">id</th>
<th width = "15%">Date</th>
<th width = "25%">Supervisor</th>
<th width = "30%">Task Name</th>
<th width = "10%">Status</th>
<th colspan = "2" width = "7%">Action</th>
</tr>
</thead>
<tbody>';
$i=0;
while($row = $sql->fetch(PDO::FETCH_ASSOC)){
$status=$row['report_status'];
if($status=="Pending"){
$color="color:blue";
}
else {
$color="color:green";
}
$report_id = $row["report_id"];
echo'<tr>';
echo '<td><input type="checkbox" id="checkItem" name="check[]" value="'.$report_id.'"></td>';
echo '<td>'.$report_id.'</td>';
echo '<td>'.$row['report_date'].'</td>';
echo '<td>'.$row["fullname"].'</td>';
echo '<td>'.$row["task_name"].'</td>';
echo '<td align="center" style='.$color.'><strong>'.$status.'</strong></td>';
echo '<td align="center">';
echo '<form action = "view_task/view_task.php" method = "post" target="_blank">';
echo '<input type = "hidden" name = "report_id" value = "'.$report_id.'">';
echo '<button type = "submit" class="btn-primary">View</button>';
echo '</form>';
echo '</td>';
echo '<td align="center">';
echo "<form action = 'remove2.php' method = 'post' onClick=\"return confirm('Do you want to remove this reports?')\">";
echo '<input type = "hidden" name = "from" value = "'.$from.'">';
echo '<input type = "hidden" name = "to" value = "'.$to.'">';
echo '<input type = "hidden" name = "team" value = "'.$team.'">';
echo '<input type = "hidden" name = "report_id" value = "'.$report_id.'">';
echo '<button type = "submit" class="btn-danger">Remove</button>';
echo '</form>';
echo '</td>';
echo '</tr>';
$i++;
}
echo '<tr>';
echo '<td>';
echo "<form action = 'delete_selected.php' method = 'post'>";
echo '<input type="hidden" id="checkItem" name="check[]" value="'.$report_id.'">';
echo '<button type="submit" class="btn-danger btn-sm">DELETE</button>';
echo '</form>';
echo '</td>';
echo '</tr>';
}
}
?>
delete_selected.php
<?php
include("../../../config/configPDO.php");
include("../../../config/check.php");
$checkbox = $_POST['check'];
for($i=0;$i<count($checkbox);$i++){
$report_id = $checkbox[$i];
$sql = "UPDATE ot_report SET status = 'no' WHERE report_id=:report_id";
$query = $conn->prepare($sql);
$query->execute(array(':report_id' => $report_id));
header("Location: dashboard_engineer.php");
}
?>
谁能帮我解决这个问题？谢谢
【问题讨论】：
-
如果能隔离问题就更好了。确保您的表单在多次检查时提交超过 1 个值
-
你不能有多个相同的ID，例如
checkItem -
您在外部表单中循环...在您的删除表单中它只设置了最后一个值...

@RamRaider 你能用代码给出答案吗？

@AntonyJack 你能编辑我上面的代码吗？
