Question

我正在尝试从一个输入上传两个文件，这两个文件都应该出现在uploads文件夹中，但只有一个文件路径进入数据库。

E.g。如果我上传test1.pdf和test2.pdf，它们都将进入uploads文件夹，但test1.pdf将插入数据库的两列而不是一列。

在我疯了之前，有人可以帮助我吗？

if (count($_FILES) >= 1) {


//Loop through each file
foreach ($_FILES as $id=>$file) {
    //Get the temp file path
    $tmpFilePath = $file['tmp_name'];

    //Make sure we have a filepath
    if ($tmpFilePath != "") {

        //save the filename
        $shortname = $file['name'];

        //save the url and the file
        $filePath = "uploads/" . date('d-m-Y-H-i-s') . '-' . $file['name'];

        //Upload the file into the temp dir
        if (move_uploaded_file($tmpFilePath, $filePath)) {


        $sql = "INSERT INTO " . $config_tbl_prefix . " subcontractor_qs (field1) VALUES ('$filePath')";

        mysql_query($sql);

         }
       }
     }
   }
 }

如果您想使用相同的输入字段上传两个或更多文件，请更新您的代码。在此代码中保存文件名和路径。在一次你无法使用循环获得两个文件路径。

<强> 1。重要的是删除mysql并使用pdo或mysqli

 <if (count($_FILES['enviroupload']['name']) >= 1) {
//Loop through each file
for ($i = 0; $i < count($_FILES['enviroupload']['name']); $i++) {
    //Get the temp file path
    $tmpFilePath = $_FILES['enviroupload']['tmp_name'][$i];

    //Make sure we have a filepath
    if ($tmpFilePath != "") {

        //save the filename
        $shortname = $_FILES['enviroupload']['name'][$i];

        //save the url and the file
        $filePath = "uploads/" . date('d-m-Y-H-i-s') . '-' . $_FILES['enviroupload']['name'][$i];

        //Upload the file into the temp dir
        if (move_uploaded_file($tmpFilePath, $filePath)) {

            $sql = "INSERT INTO " . $config_tbl_prefix . " subcontractor_qs         (field1, field2)

 VALUES
 ('$shortname','$filePath')";

            //mysql_query($sql);
            echo $sql;
            echo "<br>";

        }
    }
}

}

在此代码文件中，路径和文件名将保存在db中，如果只想保存文件路径则需要更新代码

将文件路径上载到数据库
