Question

我目前能够使用数组将多个单独的文件保存到文件夹。现在我想将文件夹中的各个文件路径添加到数据库中。

我如何才能将每个文件的各个路径上传到文件夹？

从那里我如何将这些单独的路径插入到我的数据库中的单独字段？

HTML：

＆＃13;

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
  <p><input type="file" name="file_array[]"></p>
  <p><input type="file" name="file_array[]"></p>
  <p><input type="file" name="file_array[]"></p>
  <input type="submit" value="Upload all files">
</form>
</body>
</html>

＆＃13;

PHP：

＆＃13;

<?php

if(isset($_FILES['file_array'])){
    $name_array = $_FILES['file_array']['name'];
    $tmp_name_array = $_FILES['file_array']['tmp_name'];
    $type_array = $_FILES['file_array']['type'];
    $size_array = $_FILES['file_array']['size'];
    $error_array = $_FILES['file_array']['error'];
	
	$imageFileType = pathinfo($path,PATHINFO_EXTENSION);
	$path = 'uploads/' . $_FILES['my-file']['name'];
	
    for($i = 0; $i < count($tmp_name_array); $i++){
        if(move_uploaded_file($tmp_name_array[$i], "uploads/".$name_array[$i])){
            echo $name_array[$i]." upload is complete<br>";
        } else {
            echo "move_uploaded_file function failed for ".$name_array[$i]."<br>";
        }
    }
}


$conn_info = "host=d port= dbname= user= password=";
        $dbconn = pg_connect($conn_info)
        or die('could not connect:' . pg_last_error());

         echo"<br/>sucessful connection";


        $query = "INSERT INTO photo2 (path) VALUES ('".$path."') ;";

        $result = pg_query($dbconn, $query);
         if (!$result) {
         $errormessage = pg_last_error();
         echo "<br/> error with query: " . $errormessage;
         exit();
         }

         echo "<br/> file uploaded to PostgreSQL";

        pg_close();

?>

获取for循环中的路径。并且还在循环中编写插入查询。数据库连接代码必须在for循环之前。

for($i = 0; $i < count($tmp_name_array); $i++){
    if(move_uploaded_file($tmp_name_array[$i], "uploads/".$name_array[$i])){
        // get path
        $path = "uploads/".$name_array[$i];
        echo $name_array[$i]." upload is complete<br>";
        // Insert query comes here
          $query = "INSERT INTO photo2 (path) VALUES ('".$path."') ;";
          pg_query($dbconn, $query);
    } else {
        echo "move_uploaded_file function failed for ".$name_array[$i]."<br>";
    }
}

您需要完整的代码。我想它可以帮助你先生。

<?php
$conn_info = "host=d port= dbname= user= password=";
$dbconn = pg_connect($conn_info) or die('could not connect:' . pg_last_error());

echo "<br/>sucessful connection";

if(isset($_FILES['file_array'])){
    $name_array = $_FILES['file_array']['name'];
    $tmp_name_array = $_FILES['file_array']['tmp_name'];
    $type_array = $_FILES['file_array']['type'];
    $size_array = $_FILES['file_array']['size'];
    $error_array = $_FILES['file_array']['error'];

    // you don't need this lines of code
    // $imageFileType = pathinfo($path, PATHINFO_EXTENSION);
    // $path = 'uploads/' . $_FILES['my-file']['name'] . '.' . $imageFileType;

    for($i=0;$i<count($tmp_name_array);$i++) {
        $path = "uploads/" . $name_array[$i];

        if(move_uploaded_file($tmp_name_array[$i], $path)){
            $query = "INSERT INTO photo2 (path) VALUES ('".$path."');";
            $result = pg_query($dbconn, $query);

            if (!$result) {
                $errormessage = pg_last_error();
                echo "<br/> error with query: " . $errormessage;

                exit();
            } else {
                echo $name_array[$i]." upload is complete<br>";
            }
        } else {
            echo "move_uploaded_file function failed for ".$name_array[$i]."<br>";
        }
    }
}

echo "<br/> file uploaded to PostgreSQL";
pg_close();

?>
