PHP-在自定义Wordpress数据库中上载CSV数据

我的自定义表格：

id              int(11)
product_type    varchar(210)
product_serial  varchar(210)
created_at      datetime


//Upload CSV File
if (isset($_POST['submit'])) {

        if (is_uploaded_file($_FILES['upload_csv']['tmp_name'])) {

                echo "<h1>" . "File ". $_FILES['upload_csv']['name'] ." uploaded successfully." . "</h1>";
        }


        //Import uploaded file to Database
        $handle = fopen($_FILES['upload_csv']['tmp_name'], "r");

        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
            $wpdb->insert("my_custom_table", array(
                    "product_type" => $data[0],
                    "product_serial" => $data[1],
                    "created_at" => current_time('mysql', 1)
                 ));
        }

        fclose($handle);

        print "Import done";
}

Array
(
    [0] => Product Name;product_serial
)

Array
(
    [0] => iPhone 6;iphone-002
)

Array
(
    [0] => iPhone 6;iphone-003
)

Array
(
    [0] => Product Name
    [1] => product_serial
)

Array
(
    [0] => iPhone 6
    [1] => iphone-002
)

Array
(
    [0] => iPhone 6
    [1] => iphone-003
)

使用分隔符打印

$data

输出：

id              int(11)
product_type    varchar(210)
product_serial  varchar(210)
created_at      datetime


//Upload CSV File
if (isset($_POST['submit'])) {

        if (is_uploaded_file($_FILES['upload_csv']['tmp_name'])) {

                echo "<h1>" . "File ". $_FILES['upload_csv']['name'] ." uploaded successfully." . "</h1>";
        }


        //Import uploaded file to Database
        $handle = fopen($_FILES['upload_csv']['tmp_name'], "r");

        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
            $wpdb->insert("my_custom_table", array(
                    "product_type" => $data[0],
                    "product_serial" => $data[1],
                    "created_at" => current_time('mysql', 1)
                 ));
        }

        fclose($handle);

        print "Import done";
}

Array
(
    [0] => Product Name;product_serial
)

Array
(
    [0] => iPhone 6;iphone-002
)

Array
(
    [0] => iPhone 6;iphone-003
)

Array
(
    [0] => Product Name
    [1] => product_serial
)

Array
(
    [0] => iPhone 6
    [1] => iphone-002
)

Array
(
    [0] => iPhone 6
    [1] => iphone-003
)

使用上述方法，

产品名称

和

产品系列

也会被插入到数据库中，这是应该防止的。另外，分隔符

如何防止CSV列名插入并在数据库中插入正确的值

附言：使用OpenOffice插入CSV数据。分隔符是否存在格式问题？
一般的经验法则是CSV的第一行是列名，因此快速跳过计数器将为您删除第一行：

$counter = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {

    // Skip the first row as is likely column names
    if ($counter === 0) {
        $counter++;
        continue;
    }

    // Insert the row into the database
    $wpdb->insert("my_custom_table", array(
        "product_type" => $data[0],
        "product_serial" => $data[1],
        "created_at" => current_time('mysql', 1)
    ));
}

另一个问题是CSV文件可能有不同的列和行分隔符（有时列用逗号表示，有时用分号表示等等），这使得解析CSV非常困难。在本例中，您的列分隔符似乎是分号，因此修改函数参数可能会为您解决此问题：

while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) {

如果您确实必须支持多种类型的分隔符，以下代码段可能会帮助您：

$csvFilePath = $_FILES['upload_csv']['tmp_name'];
$delimiter = $this->detectDelimiter($csvFilePath);

public function detectDelimiter($csvFile)
{
    $delimiters = array(
        ';' => 0,
        ',' => 0,
        "\t" => 0,
        "|" => 0
    );

    $handle = fopen($csvFile, "r");
    $firstLine = fgets($handle);
    fclose($handle); 
    foreach ($delimiters as $delimiter => &$count) {
        $count = count(str_getcsv($firstLine, $delimiter));
    }

    return array_search(max($delimiters), $delimiters);
}

检测从以下位置获取的代码段：

希望这能有所帮助。
跳过计数器会删除第一行，即列名，但没有获取有关分隔符的代码段。如何在我的代码片段中实现相同的功能？修改了我的答案，似乎检测分隔符是相当棘手的，许多帖子建议要求用户提供CSV文件。我已经修改了我的答案，这将解决您的CSV问题，但如果您的CSV有不同的分隔符（又名逗号和/或分号），那么您将面临艰难的旅程。。。。祝你好运。
