Question

我正在使用php开发一个应用程序，我会在一个页面中添加2个按钮php，我将每个Bottons的名称传递给函数（POST），就像这样（isset（$ _ POST ['action']））但是我不能帮你做到这一点

<?php 
$host = "localhost"; 
	$user = "root"; 
	$db = "reseau"; 
	$con = @mysql_connect('localhost', 'root', '');
	$select = @mysql_select_db ('reseau') ;  

if (isset($_POST['action'])) {
   	if(isset($_POST['nom'])) $nom = htmlspecialchars(pg_escape_string($_POST['nom']));
	else      $nom="";
	if(isset($_POST['prenom'])) $prenom =  htmlspecialchars(pg_escape_string($_POST['prenom']));
	else      $prenom="";
	if(isset($_POST['email'])) $email = $email =  htmlspecialchars(pg_escape_string($_POST['email']));
	else      $email="";
	if(isset($_POST['password'])) $password =  htmlspecialchars(pg_escape_string($_POST['password']));
	else      $password="";
	if(isset($_POST['naissance'])) $naissance =  htmlspecialchars(pg_escape_string($_POST['naissance']));
	else      $naissance="";
	if(isset($_POST['sexe'])) $sexe =  htmlspecialchars(pg_escape_string($_POST['sexe']));
	else      $sexe="";
	$query = "INSERT INTO usager(nom,prenom,email,password,naissance,sexe) VALUES ('" . $nom . "', '" . $prenom . "', '" . $email . "', '" . $password . "', '" . $naissance . "', '" . $sexe . "')";
    $result = mysql_query($query);
    if (!$result) {
    $errormessage = mysql_error();
    echo "Error with query: " . $errormessage;
    exit();
    }
}
else if(isset($_POST['enter'])){
		if(empty($_POST['nom']) === false && empty($_POST['password']) === false){
			$nom = htmlspecialchars(pg_escape_string(trim($_POST['nom'])));
			$password = htmlspecialchars(pg_escape_string(trim($_POST['password'])));
			$query = mysql_query("SELECT * FROM usager WHERE nom = '$nom' AND password = '$password'")or die(mysql_error());
			$count = mysql_num_rows($query);
			if($count == 0){
				$output= "combinaison nom d'utilisateur/mot de passe incorrecte. réessayez";
			}else{
				session_start();
				$_SESSION['nom']=htmlspecialchars(pg_escape_string(trim($_POST['nom'])));
				$_SESSION['password']=htmlspecialchars(pg_escape_string(trim($_POST['password'])));
				header("Location: index1.php");
			}
		}else{
			$output= 'veuillez saisir tout les champs';
		}
	}

感谢任何帮助。

Answer 1

创建两个提交按钮。为具有不同值的两个提交输入指定相同的名称。

<input type="submit" name="btn_name" value="First Button"/>
<input type="submit" name="btn_name" value="Second Button"/>

并检查它，

if(isset($_POST) && isset($_POST['btn_name']))
{
  if($_POST['btn_name'] == "First Button")
   {
      // first button clicked
   }
  else if($_POST['btn_name'] == "Second Button")
{
  // second button clicked
}
}

Answer 2

请在两个按钮中添加名称标签，然后使用 isset（）功能进行检查

<input type="submit" name="btn1" value="btn1" />
<input type="submit" name="btn2" value="btn2" />


if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    //something posted

    if (isset($_POST['btn1'])) {
        // btn1
    } else {
        //btn2
    }
}

我怎么能用php在一个页面上做很多提交？
