带内联PHP的HTML表 [英] HTML Table with inline PHP
问题描述
我想创建一个HTML表，但是这些行应该从mysql数据库中的值生成.问题是我想要一个布尔框，用户可以在其中标记它，然后按一个按钮以更新数据库中的表.我该怎么做?
I want to create a HTML Table, but the rows should be generated from the values from a mysql database. The problem is that I want to have a boolean box where the user can mark it, and then press a button to update the table in the database. How do I do such a thing ?
到目前为止的代码:
<?php
session_start();
require("connectToEvent_log.php");
$connectToEvent = connect2db();
$uid = '2'; // for the filnal version: @$_SESSION['uid'];
$view_event = "SELECT * FROM event_log WHERE uid = $uid";
$view_event_query = mysqli_query($connectToEvent, $view_event);
$row = mysqli_num_rows($view_event_query);
$print = mysqli_fetch_array($view_event_query);
?>
<html>
<head>
<title>Events</title>
</head>
<body>
<form action="viewEvents.php" method="POST">
<table border = '1'>
<tr>
<?php
while($row != 0){
echo "<td>".$print['hours']."</td>";
echo "<td>".$print['date']."</td>";
}
?>
</tr>
</table>
<form/>
</form>
</body>
</html>
推荐答案
您可以轻松地遍历mysqli_fetch_array函数的结果以创建表行.创建复选框标记很容易完成，我假设表具有主键id，并且存储复选框值(0或1)的列称为checkbox.
You can easily iterate over the result from the mysqli_fetch_array function to create the table rows. Creating a checkbox markup is done easily, i assume that the table has a primary key id and the column, that stores the checkbox value (0 or 1) is called checkbox.
<?php
session_start();
require("connectToEvent_log.php");
$connectToEvent = connect2db();
$uid = '2'; // for the filnal version: @$_SESSION['uid'];
$view_event = "SELECT * FROM event_log WHERE uid = $uid";
$view_event_query = mysqli_query($connectToEvent, $view_event);
$num_rows = mysqli_num_rows($view_event_query);
$rows = mysqli_fetch_array($view_event_query);
?>
<html>
<head>
<title>Events</title>
</head>
<body>
<form action="viewEvents.php" method="POST">
<table border="1">
<thead>
<tr>
<td>Id</td>
<td>Date</td>
<td>Hours</td>
<td>Checkbox</td>
</tr>
</thead>
<tbody>
<?php
for ($i = 0; $i < count($num_rows); $i++) {
?>
<tr>
<td><?php print $rows[$i]["eid"]; ?></td>
<td><?php print $rows[$i]["date"]; ?></td>
<td><?php print $rows[$i]["hours"]; ?></td>
<td><input type="checkbox" name="row[<?php $rows[$i]["eid"]?>][checkbox]" value="1" <?php if ($rows[$i]["accepted"]) print ' checked="checked"'; ?>/></td>
</tr>
<?php
}
?>
</tbody>
</table>
<input type="submit" />
</form>
</body>
</html>
