與狀態和分頁mysql的問題

我打電話給一個mysql查詢，作爲不同的結果（關閉打開，掛起，所有）和分頁的各種不同的狀態，一切都很好，除了當我點擊下一頁鏈接或任何其他頁面我失去了狀態設置，例如「關閉」，並顯示所有結果。與狀態和分頁mysql的問題

我是一個PHP和MySQL的新手，所以不真的沒有如何實現這個，以便以某種方式存儲一個會話，以便一旦分頁被使用，狀態仍然被設置。

請參閱代碼。

任何幫助真的很感激。

這裏的解決方案是將您的$viewstate傳遞給您的所有分頁鏈接。示例前一個鏈接，添加&viewstate=$viewstate

if ($current_page != 1) { 
     echo '<a href="?page_id=1072&amp;startoftable=' . ($start - $display) . '&np=' . $num_pages . '&viewstate=' .$viewstate. '">Previous</a> '; 
    }

然後，在您的視圖狀態設置代碼，添加$ _GET到你的條件，因此可以判斷什麼是當前視圖狀態。

/* View state set code */ 

if (isset($_POST['showopen']) || (isset($_GET['viewstate']) && $_GET['viewstate'] == 'open')) { 
    $viewstate='open'; 
} 

if (isset($_POST['showpending']) || (isset($_GET['viewstate']) && $_GET['viewstate'] == 'pending')) { 
    $viewstate='pending'; 
} 


if (isset($_POST['showclosed']) || (isset($_GET['viewstate']) && $_GET['viewstate'] == 'closed')) { 
    $viewstate='closed'; 
} 

if (isset($_POST['show_all']) || (isset($_GET['viewstate']) && $_GET['viewstate'] == 'all')) { 
    $viewstate='all'; 
}

希望這項工作。

嗨，非常感謝，非常感謝。但現在一個小問題是我需要解決如何刪除np（頁數）的查詢字符串，並在點擊新狀態後開始行。如果您在頁面3上並單擊另一個只有一頁結果的狀態，則由於查詢字符串顯示頁面3 = 12的開始，您將得不到結果。希望是有道理的。你有什麼想法？ – Maximus

我認爲你需要計算某個視圖狀態有多少記錄。因此，如果記錄數小於頁面，請將其設置爲第1頁。 – ace

使用$ _SERVER ['REQUEST_URI'] = preg_replace（'！＆startoftable =。*！'，''，$ _SERVER ['REQUEST_URI']]破解它）; – Maximus
