如何通过单击按钮从数据库中获取相应邮件的数据？

Question

I have a table called admin tickets.我有一张名为 admin tickets 的表。 I have this situation were one of these mails, which are on the left of the screen is clicked.我有这种情况是这些邮件之一，点击屏幕左侧。 Then I want to fetch subject/text, to this mail.然后我想获取主题/文本到这封邮件。 For example I'm clicking qweqweqwe@wp.pl, and it gives me 123123123123123. The table looks like this:例如，我单击 qweqweqwe@wp.pl，它给了我 123123123123123。该表如下所示：

For now the page looks like this, because I'm iterating over the whole table to the end.现在页面看起来像这样，因为我正在遍历整个表直到最后。 This looks good.这看起来不错。 The only change I want to make is as I said, I want to click the mail on the left, and get subject/text of this mail.我想做的唯一改变就是如我所说，我想单击左侧的邮件，并获取该邮件的主题/正文。

How can I achieve it?我怎样才能实现它？

Answer 2

I would probably use Ajax for this, and then get the information that way.我可能会为此使用 Ajax，然后以这种方式获取信息。 So when you click one of the mails on the left, then you make a Ajax call to another .php , like this.因此，当您单击左侧的其中一封邮件时，您将对另一个.php进行 Ajax 调用，如下所示。

Lets say the mail is this image.假设邮件是这张图片。

echo'<img class="MAILyouWantToAttach" data-id = "'.$MAILyouWantToAttach.'" src = "../text.png">';

The Ajax success respons has to change the textareas content by its value. Ajax 成功响应必须根据其值更改文本区域内容。

$(document).on("click", ".Unflagging", function(){          
              var text= $(this).data("id");
                  $.ajax({
                    method: "post",
                    url: "AnotherFile.php",
                    data: { text: text},
                    success: function(data) {
                      $("#myTextarea").val(data);
                  },
                  error: function(data) {
                    alert("Error occurs!")
                 }
             });
        });

Then the other php file you want something like this, the echo is to print the text in the success area of the Ajax in the other .php .然后另一个 php 文件你想要这样的东西，回声是在另一个.php中打印 Ajax 成功区域中的文本。

$receiver = $_POST["text"];
$result = $connect->query("SELECT emailLogin,subject,text FROM tickets WHERE emailLogin= $receiver ");
while ($row = $result->fetch_assoc()) {
  echo $row['text'];
}

This is just a guide, but i hope it helps you on your way to success.这只是一个指南，但我希望它能帮助您走向成功。
