使用標題時，從一個腳本刷新數據，而不是從另一個腳本？

Question

我使用兩個腳本，一個用於從SQL中刪除，另一個用於添加到數據庫。

我遇到的問題是，在運行添加腳本時，它將刷新即時顯示更改的頁面。然而，在運行刪除腳本時，它不會立即刷新它，似乎它會緩存輸出？

如果它確實緩存了它重定向到的輸出，爲什麼一個腳本顯示添加而另一個不顯示刪除？

添加腳本

// Set a URL for the user to be redirected to 
$header_URL = "Location: ".WEBURL.DOCROOT."pages/parents-evening/{$_SESSION['status']}/"; 


// SQL statement using the variables from the user to insert into a specific table 
$sql = "INSERT INTO $table ($columns) VALUES ($values);"; 

// Check that the query was successful 
if(mysqli_query($conn, $sql)) 
{ 
    // Success 
    // Closes the database connection 
    mysqli_close($conn); 
    // Sets the redirect location 
    header($header_URL); 
    // Exits the script 
    exit(); 
} 
else 
{ 
    // Fail 
    // Closes the database connection 
    mysqli_close($conn); 
    // Sets the redirect location 
    header($header_URL); 
    // Exits the script 
    exit(); 
} 

刪除腳本

// Set a URL for the user to be redirected to 
$header_URL = "Location: ".WEBURL.DOCROOT."pages/parents-evening/{$_SESSION['status']}/"; 

// SQL statement to delete from the table provided where the ID is equal to either the POST or GET value 
$sql = "DELETE FROM {$table} WHERE id = {$_POST['delete_id']}{$_GET['delete_id']}"; 

// Check the query was successful 
if(mysqli_query($conn, $sql)) 
{ 
    // Success 
    // Closes the database connection 
    mysqli_close($conn); 
    // Sets the redirect location 
    header($header_URL); 
    // Exits the script 
    exit(); 
} 
else 
{ 
    // Fail 
    // Closes the database connection 
    mysqli_close($conn); 
    // Sets the redirect location 
    header($header_URL); 
    // Exits the script 
    exit(); 
}

似乎問題是，在此聲明：

$ SQL =「DELETE FROM {$表} WHERE ID = {$ _POST [ 'delete_id']} {$ _ GET [ 'delete_id']}「;

如果從POST越來越delete_id查詢將是：

$sql = "DELETE FROM {$table} WHERE id = ".$_POST['delete_id']; 

如果從GET越來越delete_id查詢將是：

$sql = "DELETE FROM {$table} WHERE id = ".$_GET['delete_id']; 

如果只有一個記錄是刪除（因爲似乎id是主鍵，所以只會有一條記錄），我會推薦使用limit 1，因爲它會加快刪除過程，如果你有巨大的da ta在你的桌子上。

限制1將告訴數據庫只刪除一條記錄，因此當1條記錄被刪除時它將停止執行。

你最終的查詢將是：

對於POST

$sql = "DELETE FROM {$table} WHERE id = ".$_POST['delete_id']." LIMIT 1"; 

對於GET

$sql = "DELETE FROM {$table} WHERE id = ".$_GET['delete_id']." LIMIT 1";
