Question

我试图将表单数据插入到csv文件中，即逐行插入，但问题是一个接一个地附加数据，但数据插入到csv文件的同一行。

这是HTML表单：

<!DOCTYPE>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>

<body>
    <form id="form1" name="form1" method="post" action="insert.php">
    <table border=1>
        <tr>
            <td width="30"><span>First Name</span></td>
            <td width="30"><input type="text" name="fn" id="fn" /></td>
        </tr>
        <tr>
            <td width="30"><span>Last Name</span></td>
            <td colspan="3"><input name="ln" type="text" id="ln" size="50" /></td>
        </tr>
        <tr>
            <td width="71">Address</td>
            <td width="10"><input class="" name="address" type="text" id="address" size="100" /></td>
        </tr>
        <tr><td></td>
            <div align="center">
            <td><input type="submit" name="Submit" id="Submit" value="Submit" />
            <input type="reset" name="Reset" id="button" value="Reset" />
            </td>
            </div>
        </tr>
    </table>
    </form>
</body>
</html>

这是php程序：

<?php

$first=$_POST["fn"];
$last=$_POST["ln"];
$address=$_POST["address"];

echo "$first <br> $last <br> $address";

if(!empty($first) || !empty($last) || !empty($address)){

$cvsData = $first . "," . $last . "," . $address ;

$fp = fopen("formdata.csv","a"); // $fp is now the file pointer to file $filename

    if($fp)
    {
        fwrite($fp,$cvsData)"; // Write information to the file
        fclose($fp); // Close the file
    } 
}
?>

我第一次插入细节： abcd，efgh，ijkl 我第二次插入细节时： abcd，efgh，ijkl

问题出在csv文件中第一行排除，第二次我插入数据追加到同一行。如下图所示：请求发现。 enter image description here

附上新文件：我添加时不会更新：fwrite（$ fp，$ cvsData。“\ n”）; 请找到快照： enter image description here

Answer 1

你错过了换行符。你想要：

fwrite($fp,$cvsData."\n")

Answer 2

这对我有用：

if(!empty($first) || !empty($last) || !empty($address)){

$cvsData = $first . "," . $last . "," . $address  . "\n"; // Add newline

$fp = fopen("formdata.csv","a"); // $fp is now the file pointer to file $filename

    if($fp)
    {
        fwrite($fp,$cvsData); // Write information to the file
        fclose($fp); // Close the file
    }
}

此外，您在fwrite($fp,$cvsData)"; // Write information to the file

时遇到语法错误

应为fwrite($fp,$cvsData); // Write information to the file

Answer 3

在\n中添加$cvsData：

$cvsData = "\n" . $first . "," . $last . "," . $address ;

在php中逐行将表单数据插入到csv文件中
