我的图片没有上传到我的数据库

Question

请帮助任何人。我一直在调试几天。我只是有一个问题，我会很高兴，如果你帮助我。

我的图像无法上传到我的数据库。它甚至不会给我一个错误。它只是上传我的查询的其他组件，将图像留在后面。这里是我的代码

<?php 
global $connection; 
if(isset($_POST['submit'])){ 

    $post_category_id = $_POST['post_category_id']; 
    $post_title = $_POST['post_title']; 
    $post_author = $_POST ['post_author']; 
    $post_status = $_POST['post_status']; 

    $post_image = isset($_FILES['post_image']['image_name']); 
    $post_image_temp = isset($_FILES['post_image']['temp_name']); 

    $post_tags = $_POST['post_tags']; 
    $post_comment_count = 4; 
    $post_date = date('d-m-y'); 
    $post_content = $_POST['post_content']; 
    $post_status = $_POST['post_status']; 
    move_uploaded_file($post_image_temp, '../images/$post_image'); 

    $query = "INSERT INTO posts (post_category_id, post_title, post_author, post_status, post_image, post_tags, post_comment_count, post_date, post_content) VALUES ('{$post_category_id}', '{$post_title}', '{$post_author}', '{$post_status}', '{$post_image}', '{$post_tags}', {$post_comment_count}, now(), '{$post_content}') "; 

    $result = mysqli_query($connection, $query); 
    if ($result){ 
     echo "Post Published"; 
    } else { 
     echo "(Error Code:" . $_FILES['post_image']['error'] . ")"; 
    } 
} 
?> 


<form action="" method="post" enctype="multipart/form-data"> 

    <div class="form-group"> 
     <label for="post_title">Title</label> 
     <input type="text" name ='post_title' class="form-control" > 
    </div> 
    <div class="form-group"> 
     <label for="Post_author">Post Author</label> 
     <input type="text" name ='post_author' class="form-control"> 
    </div> 

    <div class="form-group"> 
     <label for="post_category_id">Post Category</label> 
     <input type="text" name ='post_category_id'class="form-control" > 
    </div> 
    <div class="form-group"> 
     <label for="post_status">Post Status</label> 
     <input type="text" name ='post_status' class="form-control"> 
    </div> 
    <div class="form-group"> 
     <label for="post_image">Upload Image</label> 
     <input type="file" name ="post_image" id="post-image" class="form-control" > 
    </div> 
     <div class="post tags"> 
     <label for="post_tags">Post Tags</label> 
     <input type="text" name ='post_tags'class="form-control" > 
    </div> 
    <div class="post comment count"> 
     <label for="post_comment_count">Post Comment Count</label> 
     <input type="text" name ='post_comment_count'class="form-control" > 
    </div> 

    <div class="form-group"> 
     <label for="post_date">post date</label> 
     <input type="date" name ='post_date'class="form-control" > 
    </div> 
    <div class="form-group"> 
     <label for="post_content">Post content</label> 
     <textarea name="post_content" id="" cols="30" rows="10"></textarea> 
    </div> 
    <input class= "btn btn-primary"type="submit" name = "submit" value="Publish Post"> 

</form> 

请注意我已经完全控制权限到我从上传的位置。我相信你会发现我的IMAGE_NAME的isset功能和image_temp_name这是因为没有它，我只是得到一个

未定义的变量错误

你需要更改文件上传的代码

//check if there is file uploaded 
$post_image = ''; 
if(!empty($_FILES['post_image']) && ($_FILES['post_image']['error']=='0' || $_FILES["pictures"]["error"] == UPLOAD_ERR_OK)){ 
    // get the file name 
    $post_image = $_FILES['post_image']['name']; 
    // get temp name 
    $post_image_temp = $_FILES['post_image']['temp_name']; 
    // code to move uploaded file to desired location on server 
    if (move_uploaded_file($post_image_temp, "../images/$post_image")) { 
     echo "File successfully uploaded.\n"; 
    } else { 
     echo "File not uploaded\n"; 
    } 
}
