我想導出基於選定本月

<div id="page-wrapper"> 

     <div class="container-fluid">

export.php

出口按鈕工作的數據，但我想過濾我的數據就像在我的表中index.php基於選擇的月份......但現在我只能執行時，我點擊導出按鈕我的數據庫上的整個數據獲取輸出到.csv

<?php 
    require_once 'dbconfig.php'; 


header('Content-Type: text/csv'); 
header('Content-Disposition: attachment;filename=exported-data.csv'); 

$stmt = $db_con->prepare("SELECT * FROM tblguest "); 

$stmt->execute(); 


$filename = date('d.m.Y').'.csv'; 

$data = fopen($filename, 'w'); 


    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) { 
$csv = implode(',', $row) . "\n"; 
fwrite($data, $csv); 
print_r($csv); 
} 

echo "\r\n"; 

fclose($data); 

?> 

Answer 1

您可以使用下面的代碼。您首先需要根據您的情況選擇數據庫。

在HTML中設置選擇下拉按鈕，並在Get請求中使用Day參數。

<label>Day</label> 
    <select id='lead_ids' name='lead_ids' onchange="location = this.value;"> 
     <option value=""> ... </option> 
     <option value="search"> All </option> 
     <option value="search?day=Monday">{{ Monday }}</option> 
     <option value="search?day=Tuesday">{{ Tuesday }}</option> 
    </select> 

這樣你就可以根據城市，使鏈接，你可以使用$ _GET參數，或者您的應用程序的方式獲取參數。

$q = "SELECT * FROM tblguest"; 
    if(!empty($_GET('day'))) { 
     $q .= ' WHERE day= ' . $_GET('day'); 
    } 
    $stmt = $db_con->prepare($q); 

    $stmt->execute(); 
    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) { 
     $result[] = $row; 
    } 
    $file_name = "downloads/".date('dmY_His').".csv"; 
    // call the csv export 
    exportToCsv($result, $file_name); 

這樣你就可以用不同的參數添加多個條件。

調用此函數將其導出爲CSV。

function exportToCsv($array, $file_name = "export.csv", $delimiter=";") { 
     $f = fopen($file_name, "w"); 
     $head = array_keys($array[0]); 

     fputcsv($f, $head); 
     foreach ($array as $line) { 
      fputcsv($f, $line); 
     } 

     if (file_exists($file_name)) 
     { 
      header('Content-Description: File Transfer'); 
      header('Content-Type: text/csv'); 
      header('Content-Disposition: attachment; filename='.basename($file_name)); 
      header('Expires: 0'); 
      header('Cache-Control: must-revalidate'); 
      header('Pragma: public'); 
      header('Content-Length: ' . filesize($file_name)); 
      ob_clean(); 
      flush(); 
      readfile($file_name); 
      exit; 
     } 
    }
