export.php

导出按钮正在工作，但我想根据所选月份在index.php中的表中过滤我的数据......但是现在我只能在我点击导出按钮时执行整个数据在我的数据库上获得输出到.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

您可以使用以下代码。首先需要根据条件选择数据库。

在You HTML中设置选择下拉按钮，并在Get request中使用Day参数。

    <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>

通过这种方式，您可以根据城市建立链接，您可以使用$ _GET参数或您的申请方式获取参数。

    $q = "SELECT * FROM tblguest";
    if(!empty($_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);

这样您就可以使用不同的参数添加多个条件。

调用此函数将其导出为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;
        }
    }
