如何使用php將Web表單數據插入到csv文件中

Question

我試圖通過網絡表單在csv文件中實現數據存儲，我嘗試下面的代碼保存在“form.html”，“form1.php”，“formTest.csv”，這三個都在同一目錄中。

<form id="form1" name="form1" method="post" action="form1.php">
<table class="formatTblClass">
<tr>

</tr>
<tr>
<td width="68"><span>First Name</span></td>
<td width="215"><input class="<?=$aClass;?>" type="text" name="fn" id="fn" /></td>
<td width="62"><span>Last Name</span></td>
<td colspan="3"><input class="<?=$aClass;?>" name="ln" type="text" id="ln" size="50" /></td>
</tr>
<div align="center">
<input type="submit" name="Submit" id="Submit" value="Submit" />
<input type="reset" name="Reset" id="button" value="Reset" />
</div>
</table>
</form>  

現在是form1.php腳本

<?php

$fn = $_POST['fn'];
$ln = $_POST['ln'];
if(empty($fn) || empty($ln))
  {//show the form
  $message = 'Fill in areas in red!';
  $aClass = 'errorClass';
}
$cvsData = $fn . "," . $ln . "\n";
$fp = fopen("formTest.csv","a");
if($fp){
  fwrite($fp,$cvsData); // Write information to the file
  fclose($fp); // Close the file
}
?>  

現在是formTest.csv文件

如果我在瀏覽器中運行它並再次刷新csv文件，我得到如下圖所示的輸出

如何獲得正確的用戶輸入輸出？

Answer 1

<?php
    $fn = $_POST['fn'];
    $ln = $_POST['ln'];


    if(empty($fn) || empty($ln))
    {
        //show the form
        $message = 'Fill in areas in red!';
        $aClass = 'errorClass';
    }
    else
    {
        $fp = fopen('formTest.csv', 'w');

        $cvsData = $fn . "," . $ln . "\n";
        fputcsv($fp, $cvsData);//use fputscv()
        fclose($fp);
    }

?>

Answer 2

嘗試在代碼中添加標題：

header("Content-type: text/csv");

Answer 3

試試這個吧。

   <?php
    if(isset($_POST['fn']))
    {
    $csv=array();// take an array
    $fn = $_POST['fn'];
    $ln = $_POST['ln'];

    $csv[]=$fn;
    $csv[]=$ln;  //push the values in an array.

    if(empty($fn) || empty($ln))
      {//show the form
      $message = 'Fill in areas in red!';
      $aClass = 'errorClass';
    }

    $fp = fopen("formTest.csv","a");
    if($fp)
    {
      foreach ($csv as $val)
      {
         fputcsv($fp, $val); //write data in csv file.
      }
      fclose($fp); // Close the file
    }
}
    ?>
