单个PHP表单,带有2个(编辑和删除)按钮

Question

我正在尝试设置一个带有2个按钮的表单 - "DELETE"在页面delete.php上运行,"EDIT"在edit.php上运行.

所以我需要一个不同的动作,取决于他们点击了哪个按钮......

这是我的代码.

$con = mysql_connect("localhost","user","password");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("test", $con);

$result = mysql_query("SELECT * FROM myTable");

// Need to change the action depending on what button is clicked
echo "<form name='wer' id='wer' action='delete.php' method='post' >";
echo "<table border='1'>";

while($row = mysql_fetch_array($result))
  {
    echo "<tr>";
    echo "<td>" . $row['id'] . "</td>";
    echo "<td>" . $row['page_title'] . "</td>";
    echo "<td><input type='radio' name='test1' value='" . $row['id'] . "' /></td>";
    echo "</tr>";
  }

echo "<tr>";
echo "<td>&nbsp;</td>";
echo "<td>&nbsp;</td>";
echo "<td><input type='submit' name='delete' value='Delete' /> <input type='submit' name='edit' value='Edit' /></td>";
echo "</tr>";
echo "</table>";
echo "</form>";

mysql_close($con);

Answer 1

检查isset($_POST['delete'])和isset($_POST['edit']).

但是,首先使用删除按钮是个坏主意.当按下键,浏览器通常使用的第一个按钮-在一个表格并按Enter键不应该删除任何东西.ENTER

Answer 2

你可以用JavaScript做到这一点:

<input type='button' value='Delete' onclick='
    this.form.action = "delete.php";
    this.form.submit();
' />

或者你可以使用PHP,通过表单操作,比如说,action.php它将包含:

if (!empty($_REQUEST['delete'])) {
    require_once dirname(__FILE__) . '/delete.php';
else if (!empty($_REQUEST['edit'])) {
    require_once dirname(__FILE__) . '/edit.php';
}
