我正在尝试使用 2 个不同的提交按钮从同一页面上的表单提交数据，如您所见，这些是按钮：
保存按钮：
type="submit" name="button" value="guardar" id="guardarcalificaciones"更新按钮
type="submit" name="button" value="actualizar" id="actualizarCalificaciones"注意：我正在使用 PDO
我想要做的是每个按钮都有不同的行为并将数据从表单发送到同一页面，目前我有这段代码可以发送数据并成功保存！但我希望这仅适用于保存按钮
name="guardar" value="guardar" id="guardarcalificaciones"name="actualizar" value="actualizar" id="actualizarCalificaciones"$query = "UPDATE dgirew.dbo.actas_w
SET calif = :calif,
exp_prof_calif = :exp_prof_calif,
fecha_modicalif = :fecha_modicalif,
estatus = '3'
WHERE exp_alum = :exp_alum
AND asig = :asig
AND gpo = :gpo
AND folio = :folio
";
这是它在同一个名为 indexGrupo.php 的文件中的形式
<form method="POST" action="indexGrupo.php" id="formularioActas">
<div class="table-responsive">
<table id="ActasGrupo" class="boleta">
<tbody>

</form>
发送数据并成功保存！，但它是通过两个按钮发送的，我只希望使用
save buttonupdate buttoninclude_once './model/loginModel.php';
$model = new loginModel();
$conn = $model->connect();
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
var_dump($_POST);
foreach ($_POST as $key => $value) {
if (strpos($key, 'calif_') === 0) {
$num_registro = substr($key, strlen('calif_'));
// update the rating in the database
$query = "UPDATE dgirew.dbo.actas_w
SET calif = :calif,
exp_prof_calif = :exp_prof_calif,
fecha_altacalif = :fecha_altacalif,
estatus = '1'
WHERE exp_alum = :exp_alum
AND asig = :asig
AND gpo = :gpo
AND folio = :folio";
$stmt = $conn->prepare($query);
$stmt->bindParam(':calif', $value);
$stmt->bindParam(':exp_alum', $_POST['exp_alum_' . $num_registro]);
$stmt->bindParam(':asig', $_POST['asig']);
$stmt->bindParam(':gpo', $_POST['gpo']);
$stmt->bindParam(':folio', $_POST['folio']);
$stmt->bindParam(':exp_prof_calif', $_SESSION['exp_prof_titular']);
$fecha = date('Y-m-d H:i:s') . '.000';
$stmt->bindParam(':fecha_altacalif', $fecha);
if (!$stmt->execute()) {
//show error if the data could not be inserted correctly
var_dump($stmt->errorInfo());
}
}
}
// Gets the number of records affected by the query
$rowCount = $stmt->rowCount();
if ($rowCount > 0) {
echo '<div class="alert alert-success" role="alert">';
echo '<button type="button" class="close" data-dismiss="alert" aria-label="Close">';
echo '<span aria-hidden="true">×</span></button>';
echo '<h4>¡Éxito!</h4>';
echo '<p>Group<strong>' . $_POST['gpo'] . '</strong> ratings have been saved.</p>';
echo '<hr>';
echo '<p class="mb-0"><strong>NOTA:</strong> You only have<strong> 1 </strong> chance to correct the grades for this group</p>';
echo '</div>';
}
}
如果使用 PHP 的 isset() 函数单击“保存”或“更新”按钮，我认为它可以工作。如果按下“保存”按钮，将执行保存数据的代码，而如果按下“刷新”按钮，将执行更新数据的代码。但我不知道如何实现它
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
if(isset($_POST['guardar'])){
// Code to save the data
} else if(isset($_POST['actualizar'])){
// Code to update the data
}
}
