将CSV文件转换为Mysql数据库PHP

标签: php mysql wordpress csv

我有一个我在Wordpress中编写的php函数。我正在将一个CSV文件放在与我的插件功能相同的文件夹中,并尝试将其输入数据库。

我在wp-config.php中启用了错误报告 以及我自己的php

我收到一条错误消息。

SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'wuno_inventory' already exists

我的代码会删除表并创建它。分别和一起测试。一旦我进入导入csv文件部分没有任何反应。

所以我的代码正在被阅读,但显然没有执行。

任何想法都将不胜感激。非常感谢你。

function productsExec() {
      $hostname='localhost';
      $username='username';
      $password='password';
      $database='databaseName';
      $table_name = "wuno_inventory";
      // path where your CSV file is located
      define('CSV_PATH','');
      // Name of your CSV file
      $csv_file = CSV_PATH . "inventory.csv"; 

      try {
      $dbh = new PDO("mysql:host=$hostname;dbname=$database",$username,$password);
      $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 
      $sql = "DROP TABLE IF EXISTS $table_name";
      $dbh->query($sql);

      $sql = "CREATE TABLE " . $table_name . " (
      id int(8) NOT NULL AUTO_INCREMENT,
      wuno_product varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
      wuno_description varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
      wuno_alternates varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
      wuno_onhand varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
      wuno_condition varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
      PRIMARY KEY  (id)
    ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;";
      $dbh->query($sql);

    if (($handle = fopen($csv_file, "r")) !== FALSE) {
           fgetcsv($handle);   
           while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
                $num = count($data);
                for ($c=0; $c < $num; $c++) {
                  $col[$c] = $data[$c];
                }

         $col1 = $col[0];
         $col2 = $col[1];
         $col3 = $col[2];
         $col4 = $col[3];
         $col5 = $col[4];

        // SQL Query to insert data into DataBase
        $query = "INSERT INTO " . $table_name . "(wuno_product, wuno_description, wuno_alternates, wuno_onhand, wuno_condition) 
        VALUES('".$col1."','".$col2."','".$col3."','".$col4."','".$col5."')";
        $results = $dbh->query( $query );
        }
        fclose($handle);
        }
        if ($dbh->query($sql)) {
        echo "<script type= 'text/javascript'>alert('New Record Inserted Successfully');</script>";
        }
        else{
        echo "<script type= 'text/javascript'>alert('Data not successfully Inserted.');</script>";
        }
        $dbh = null;
        }
        catch(PDOException $e)
        {
        echo $e->getMessage();
        }  
 }

我从你已经尝试wpdb->query($sql); ??

的注释掉的代码中获取它

编辑:

在$ sql查询字符串的末尾添加分号:)

$sql = "DROP TABLE IF EXISTS $table_name;"; // see the ; inside the quotes

$query = "INSERT INTO " . $table_name . " (wuno_product, wuno_description, wuno_alternates, wuno_onhand, wuno_condition) 
VALUES('".$col1."','".$col2."','".$col3."','".$col4."','".$col5."');";

//从最后一个角色添加了第3个:;在引号内,以及'('

之前的空格

最后,就我所知,$ col4和$ col5是未定义的,所以这可能会导致整个查询无效。
