我目前正在创建一个简单的 PHP 网站，可以显示 NBA 球队和各自球员的列表。我目前正在做的事情之一是添加从页面本身上传图像的功能，而不是转到 PHPMyAdmin。
这是页面现在的样子:
我正在尝试弄清楚如何添加团队 Logo ，就像添加新的团队名称一样。正如您在底部看到的，有一个“添加团队”选项，允许用户添加新团队，并且该团队将在数据库中注册。
我尝试编写一些 PHP 代码来实现上传图像的过程，但未能成功。
team_list.php
<?php
error_reporting(0);
require_once('../Model/database.php');
// Get all categories
$query = 'SELECT * FROM categories
ORDER BY categoryID';
$statement = $db->prepare($query);
$statement->execute();
$teams = $statement->fetchAll();
$statement->closeCursor();
// Initialize message variable
$msg = "";
// If upload button is clicked ...
if (isset($_POST['upload'])) {
// Get image name
$image = $_FILES['image'];
// image file directory
$target = "images/".basename($image);
$sql = "INSERT INTO categories (img) VALUES ('$image')";
// execute query
mysqli_query($db, $sql);
if (move_uploaded_file($_FILES['image']['tmp_name'], $target)) {
$msg = "Image uploaded successfully";
}else{
$msg = "Failed to upload image";
}
}
$result = mysqli_query($db, "SELECT * FROM categories");
?>

这是 add_team.php 文件，它从数据库获取数据
<?php
// Get the team data
$name = filter_input(INPUT_POST, 'name');
// Validate inputs
if ($name == null) {
$error = "Invalid team data. Check all fields and try again.";
include('../Error/error.php');
} else {
require_once('../Model/database.php');
// Add the product to the database
$query = 'INSERT INTO categories (categoryName)
VALUES (:team_name)';
$query = "INSERT INTO categories (image) VALUES ('$fileName', '$content')";
$statement = $db->prepare($query);
$statement->bindValue(':team_name', $name);
$statement->execute();
$statement->closeCursor();
// Display the team List page
include('team_list.php');
}
?>
这就是standing.php页面的样子
更新了 add_team.php
// Get the team data
$name = filter_input(INPUT_POST, 'name');
// Validate inputs
if ($name == null) {
$error = "Invalid team data. Check all fields and try again.";
include('../Error/error.php');
} else {
require_once('../Model/database.php');
// Add the product to the database
$query = 'INSERT INTO categories (categoryName)
VALUES (:team_name)';
$query = "INSERT INTO categories (image) VALUES ('$fileName', '$content')";
$statement = $db->prepare($query);
$statement->bindValue(':team_name', $name);
$statement->execute();
$statement->closeCursor();
// Display the team List page
include('team_list.php');
// This is the directory where images will be saved
$target = "../images/";
$target = $target . basename( $_FILES['image']['name']);
// This gets all the other information from the form
$filename = basename( $_FILES['image']['name']);
$team_name = $_POST['team_name'];
// Write the file name to the server
if(move_uploaded_file($_FILES['image']['tmp_name'], $target)) {
//Tells you if its all ok
echo "The file ". basename( $_FILES['image']['name']). " has been uploaded, and your information has been added to the directory";
// Connects to your Database
mysql_connect("renwid", "password") or die(mysql_error()) ;
mysql_select_db("nba") or die(mysql_error()) ;
//Writes the information to the database
mysql_query("INSERT INTO categories (img, team_name)
VALUES ('$filename', '$team_name')") ;
} else {
//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
}
?>
最佳答案
您必须先成功上传到文件夹，然后才能将记录添加到数据库中
<?php
if(isset($_POST['submit'])) {
// This is the directory where images will be saved
$target = "images/";
$target = $target . basename( $_FILES['image']['name']);
// This gets all the other information from the form
$filename = basename( $_FILES['image']['name']);
$team_name = $_POST['team_name'];
// Write the file name to the server
if(move_uploaded_file($_FILES['image']['tmp_name'], $target)) {
//Tells you if its all ok
echo "The file ". basename( $_FILES['image']['name']). " has been uploaded, and your information has been added to the directory";
// Connects to your Database
// mysql_connect("localhost", "root", "") or die(mysql_error()) ;
// mysql_select_db("your_db") or die(mysql_error()) ;
//Writes the information to the database
// mysql_query("INSERT INTO picture (image, team_name)
// VALUES ('$filename', '$team_name')") ;
} else {
//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
}
?>
您的 HTML 应该是
<form action="" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="image" id="image">
<input type="text" name="team_name" id="team_name">
<input type="submit" value="Submit" name="submit">
</form>
