上传带有评论表单的图片

Question

我的网站上有一个 cmets 区域。它显示默认图像，然后显示人员评论。我想设置表单，以便当一个人发送评论时，他们可以选择将自己的小图像上传到图像文件夹。当表单发送时，我希望 image_path 记录填充图像在图像文件夹中的位置。即图像/myphoto.jpg 这是表格

   <form method="post" enctype="multipart/form-data" class="comment-form" action="form-post.php">
    <table class="submit-table">
    <tr>
            <td><p>First Name:</p></td>
            <td><input type="text" name="First" /></td>
        </tr>
        <tr>
            <td><p>Last Name</p></td>
            <td><input type="text" name="Last" /></td>
    </tr>
    <tr>
            <td><p>Your Comment: </p></td>
            <td><textarea name="Comment" rows="10" cols="60"></textarea></td>

    </tr>
        <tr>
        <td><input type="file" name="image_path" accept=".jpeg,.jpg,.png" />
        <p>Feel free to upload a small photo of yourself (Optional)</p>
        </td>
        </tr>
        <tr>
 <td><input type="submit" name="submit" class="btn btn-primary" value="submit"/></td>  <td>All Comments are moderated and will be posted once approved.</td>
        </tr>
    </table>
</form>  

这里是表单处理程序

 <?php

//$sql = "SELECT ID, firstname, Comment, Image_path FROM comment";
//   
//$result = $conn->query($sql);


if ($_SERVER["REQUEST_METHOD"] == "POST") {

$firstname = $_POST["First"];
$lastname = $_POST["Last"];
$comment = $_POST["Comment"];
$imagepath = $_POST["image_path"];

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "INSERT INTO comment (Comment, firstname, lastname, Image_path, Approved)
VALUES ('$comment', '$firstname','$lastname','$imagepath','2')";

if ($conn->query($sql) === TRUE) {

    echo "<h4>Thankyou - We have received your comment.</h4>";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
}

$target_dir = "images/";
$target_file = $target_dir . basename($_FILES["image_path"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file, PATHINFO_EXTENSION);

// Check if image file is a actual image or fake image
if (isset($_POST["submit"])) {

    if ($target_file == "upload/") {
        $msg = "cannot be empty";
        $uploadOk = 0;
    } // Check if file already exists
    else if (file_exists($target_file)) {
        $msg = "Sorry, file already exists.";
        $uploadOk = 0;
    } // Check file size
    else if ($_FILES["image_path"]["size"] > 5000000) {
        $msg = "Sorry, your file is too large.";
        $uploadOk = 0;
    } // Check if $uploadOk is set to 0 by an error
    else if ($uploadOk == 0) {
        $msg = "Sorry, your file was not uploaded.";

        // if everything is ok, try to upload file
    } else {
        if (move_uploaded_file($_FILES["image_path"]["tmp_name"], $target_file)) {
            $msg = "The file " . basename($_FILES["image_path"]["name"]) . " has been uploaded.";
        }
    }
}
$conn->close();

?>

我已将信息上传到数据库并将图像上传到图像文件夹，但文件未链接到图像路径。有人可以告诉我该怎么做。谢谢。

我设法回答了我自己的问题，其实很简单。我使用了目标文件变量并将其作为图像路径的值

<?php
    if ($_SERVER["REQUEST_METHOD"] == "POST") {

$firstname = $_POST["First"];
$lastname = $_POST["Last"];
$comment = $_POST["Comment"];
$target_dir = "images/";
$target_file = $target_dir . basename($_FILES["image_path"]["name"]);
$uploadOk = 1; 

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "INSERT INTO comment (Comment, firstname, lastname, Image_path, Approved)
VALUES ('$comment', '$firstname','$lastname','$target_file','2')";  

if ($conn->query($sql) === TRUE) {

    echo "<h4>Thankyou - We have received your comment.</h4>";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
}

$target_dir = "images/";
$target_file = $target_dir . basename($_FILES["image_path"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file, PATHINFO_EXTENSION);

// Check if image file is a actual image or fake image
if (isset($_POST["submit"])) {

    if ($target_file == "upload/") {
        $msg = "cannot be empty";
        $uploadOk = 0;
    } // Check if file already exists
    else if (file_exists($target_file)) {
        $msg = "Sorry, file already exists.";
        $uploadOk = 0;
    } // Check file size
    else if ($_FILES["image_path"]["size"] > 5000000) {
        $msg = "Sorry, your file is too large.";
        $uploadOk = 0;
    } // Check if $uploadOk is set to 0 by an error
    else if ($uploadOk == 0) {
        $msg = "Sorry, your file was not uploaded.";

        // if everything is ok, try to upload file
    } else {
        if (move_uploaded_file($_FILES["image_path"]["tmp_name"], $target_file)) {
            $msg = "The file " . basename($_FILES["image_path"]["name"]) . " has been uploaded.";
        }
    }
}
$conn->close();
?>
