我正在使用ajax，javascript，php，还有新功能。
在这个场景中，当我点击该按钮时，我在index.html页面中有一个带onclick功能的按钮，我希望它在发布和id时将我重定向到另一个我的getdata.php页面。因此，当我被重定向到我的getdata.php页面时，我只需要使用该ID进行查询。
触发重定向的按钮位于index.html <button class="btn btn-default print" name="print" data-username="{{"'.$row['msid'].'"}}" onclick="generatepdf()"><span class="icon-printer"></button>
我现在使用的以下代码。我希望我能在这里得到很多帮助。
的index.html
<?php
session_start();
$conn = mysqli_connect("localhost","root","1234","a0");
?>

答案 0 :(得分：1)
简单的方法是不使用JS或Jquery满足您的要求。只需使用HTML表单和PHP，就像在index.php。
<?php
//In you index.php
//.....................
//..........................
//your other codes
//......................
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
?>
<form method="post" action="getdata.php">
<input type="hidden" name="my_id" value="<?php echo $row['msid']; ?>" />
<input type="submit" value="REDIRECT AND POST MY ID" />
</form>
<?php
}
} else {
echo "0 results";
}
//.................
//.................
您只需使用此表单代码替换按钮代码，由于表单属性getdata.php，您的ID将被发布并重定向到action="getdata.php"页面。
请参阅表单方法post这意味着您的表单将使用POST方法提交。现在在getdata.php文件中执行以下操作
<?php
$posted_id = $_POST['my_id'];
echo $posted_id;
//now get data from DB using this id
//get data from db where id = $posted_id
这不是getdata.php的完整代码，但您将使用此代码至少看到您发布的ID（从index.php到getdata.php）。有很多事情要做，比如检查http方法，错误处理等等。
