Php Select 行通过 html 形式，并写入txt文件

Question

我有一个产品库存数据库，其中包含每个产品的库存量和我们的价格。我试图做到这一点，以便当我键入 12345 部分 # 时，它会在 table inventory 中搜索 $POST_partnumber。并获取零件号 + 我们对该商品的价格，然后将我输入的每个零件号写入一个 txt 文件，然后按回车键。

partnumber ourprice
partnumber ourprice
partnumber ourprice
partnumber ourprice

我开始获取代码，我将自己添加一些额外的功能，但无法获取它来搜索用户输入并将列 our price 和 part number 放入一个 txt 文件。谢谢

这是我发现的：

$fp1 = fopen( 'obspg.txt', 'w' );

$outPut = "RETSKU\tProduct Title\tDetailed Description\tProduct Condition\tSelling Price\tAvailability\tProduct URL\tImage URL\tManufacturer Part Number\tManufacturer Name\tCategorization\tGender\tsize\tColor\n";

//retrive records from database and write to file
$result = mysqli_query($con,"SELECT * FROM `TABLE 1` ");
while($row = mysqli_fetch_array($result))
{
$outPut .= $row[`id`]."\t".$row[`title`]."\t".  $row[`description`]."\t".$row[`condition`]."\t". $row[`price`]."\t".$row[`availability`]."\t".$row[`link`]."\t". $row[`image_link`]."\t".$row[`mpn`]."\t".$row[`brand`]."\t".$row[`google_product_category`]."\t".$row[`Gender`]."\t".$row[`size`]."\t".$row[`Color`]."\n";
} 

fwrite( $fp1,$outPut); 
fclose( $fp1 );

Answer 1

您可以尝试这样的操作：

<form action="yourFile.php" method="POST">
    <input type="text" name="PartNumber" id="PartNumber">
    <input type="submit" name="submit" value="Submit">
</form>
<?php

if(isset($_POST['submit']) && !empty($_POST['PartNumber'])){
    $fp1 = fopen( 'obspg.txt', 'w' );

    $outPut = "";

    //retrive records from database and write to file
    $result = mysql_query("SELECT PartNumber, Price FROM `TABLE 1` WHERE PartNumber = '".$_POST['PartNumber']."'");
    while($row = mysql_fetch_assoc($result))
    {
        $outPut .= $row['PartNumber']."\t".$row['Price']."\t\n";
    } 

    fwrite( $fp1,$outPut); 
    fclose( $fp1 );

}
?>

脚注：

您在数组中使用刻度，例如：

$row[`id`]

它们应该是常规引号 $row['id']，否则会引发错误。
http://php.net/manual/en/mysqli.error.php

所有这些数组都需要更改为常规引号。
The link 到您在问题中包含的 post，也包含刻度线；这是不正确的。

Answer 2

你也可以这样做。使用 file_put_contents() & file_get_contents()

你只需要设置一些东西

将路径 test.php 更改为您的文件名
连接数据 $host, $user, $pass, $dbdb
Table & 字段名称

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>

<!-- path to current page -->
<form action="test2.php" method="POST">
Partnumber: <input type="text" name="part"><input type="submit" name="submit" value="Submit">
</form> 

</body>
</html> 

<?php

//connection data
$user = "";
$pass = "";
$host = "";
$dbdb = "";

$connect = mysqli_connect($host, $user, $pass, $dbdb);
if(!$connect)
{
    trigger_error('Error connection to database: '.mysqli_connect_error());
}

if(isset($_POST['submit']) && !empty($_POST['part'])){

    //retrive records from database and write to file
    $result = mysqli_query($connect,"SELECT * FROM `table` WHERE `partnumber` = '".$_POST['part']."'");

    //count rows, number > 0 then partnumber exists
    if(mysqli_num_rows($result) > 0){


        while($row = mysqli_fetch_array($result))
        {

            //check if part is in stock, when > 0 its in stock
            if ($row['stock'] > 0) { 

                echo "You already have " . $row['stock'] . " of part " . $row['partNumber'] . "in stock."; 

            } else { 

                echo "<br>Added partnumber: ". $_POST['part'] . "<br><br>";

                $output = $row['partNumber']." ". $row['promoCode'] . PHP_EOL;

                $file = 'test.txt';

                //check file existence
                if (file_exists($file)) {
                    $current = file_get_contents($file);
                } else{
                    $current = null;
                }

                $current .= $output;

                echo nl2br($current);

                file_put_contents($file, $current);
            }
        }

    }else{
            echo "<br>Partnumber doesn't exist";
    }

}
