目前,我使用CRUD功能创建一个系统。我的更新功能有一些问题。问题是,它会在view_task.php显示错误,例如:
1) 未定义的索引: report_id 在第 7 行 2) 未定义的变量: task_name 在第 50 行
问题是,当我检查数据库时,数据已更新。
以下是我当前的代码:
仪表板.php
echo "<form method = 'post' action = 'view_task/view_task.php'>";
echo "<input type = 'hidden' name = 'report_id' value = '".$report_id."'>";
echo "<button type = 'submit' class='btn-primary'>View</button>";
echo "</form>";
view_task.php
<?php
require_once "../../../../config/configPDO.php";
require_once "../../../../config/check.php";
$report_id = $_POST['report_id']; //line 7
$sql = "SELECT * FROM ot_report LEFT JOIN ot_users ON ot_report.badgeid = ot_users.badgeid LEFT JOIN ot_team ON ot_team.team_id = ot_users.team_id WHERE report_id = :report_id";
$query = $conn->prepare($sql);
$query->execute(array(':report_id' => $report_id));
while($row = $query->fetch(PDO::FETCH_ASSOC)){
$report_id = $row["report_id"];
$task_name = $row["task_name"];
}
?>
<form action="update_task_name.php" method="POST">
<td><b>Task Name</b></td>
<td colspan = '2'><input type="text" class="form-control" name="task_name" value="<?php echo $task_name; ?>"/></td> //line 50
<input type="hidden" name="report_id" value="<?php echo $report_id ?>">
<td><input type="submit" class="btn btn-primary btn-block" value = "Save" onclick="confirm('Are you sure?')"></td>
</form>
update_task_name.php
<?php
require_once '../../../../config/configPDO.php';
$update = "UPDATE ot_report SET task_name = :task_name WHERE report_id = :report_id";
$stmt = $conn->prepare($update);
$stmt->bindParam(':task_name', $_POST['task_name']);
$stmt->bindParam(':report_id', $_POST['report_id']);
$stmt->execute();
class Result {}
$response = new Result();
$response->result = 'OK';
$response->message = 'Update successful';
header("Location: view_task.php");
?>
任何人都可以帮我解决这个问题吗?谢谢
