Question

我想在点击按钮时包含一个功能。代码基本上从数据库中检索数据行，每行都有一个X按钮。我希望我的解释清楚！

 ( "</td><td><a href ='delete.php?id=".
        $row['trade_id']."'>X</a>
       </td></tr>"; )

。如何在点击ahref X时执行操作（包含函数）？我该怎么做呢？例如：

if (buttonclicked)
{
require 'function.php';
}

腓

while($row = mysql_fetch_assoc($result)){
 echo "<tr><td>" . $row['trade_id'] .         
        "</td><td>" . $row['selection'] . 
        "</td><td>" . $row['date'] .
        "</td><td>" . $row['type'] .
        "</td><td>" . $row['size'] .
        "</td><td>" . $row['bidprice'] .
        "</td><td>" . $row['offerprice'] .
        "</td><td>" . $row['stoploss'] .
        "</td><td>" . $row['takeprofit'] .
        "</td><td>" . $closedb . 
        "</td><td>" . $profit . 
        "</td><td><a href ='delete.php?id=".
        $row['trade_id']."'>X</a>
       </td></tr>";  

echo "</table><br>";

Answer 1

delete.php

if(isset($_GET["id"])){
    require 'function.php';
}

Answer 2

if(isset($_GET['id'])) { //Equals your "button clicked."
   $id = intval($_GET['id']); //Thats the ID you provided through "?id=1234".
   require 'function.php';
}

Answer 3

你在delete.php文件中的

：

if(isset($_GET['id']) && $_GET['id'] != null && $_GET['id'] != ""){
    require_once 'function.php';

    $myFunction = new myFunctionClass();
    $myFunction->DoMyDeleteLogic($_GET['id']); // protect data from get before

    //or static class
    MyFunctionClass::DoMyDeleteLogic($_GET['id']);
}
else{
    echo('datas missing...'); //put a throw exception
}
