Extecuting Query With The Condition in PHP - php

Question

I have a page in which user can update their posts.
I need to update the database with different query(for different Conditions).
But every time I run update using this code, image filename changes automatically (even if I have a condition). Am I doing something wrong?
if(empty($up_image)){
$up_image = $image;
$update_query = "UPDATE posts SET title = '$up_title', image = '$up_image', categories = '$up_categories', tags = '$up_tags', post_data = '$up_post_data', status = '$up_status' WHERE id = $edit_id";
if(mysqli_query($con, $update_query)){
$msg = "Post has been Updated";
$path1 = "img/$up_image";
header("refresh:1;edit-post.php?edit=$edit_id");
if(move_uploaded_file($up_tmp_name, $path1)){
copy($path1, "../$path1");
}
}
else{
$error = "Unable to Update Post";
}
}
if(!empty($up_image)){
$up_image = preg_replace('/\s+/','',$up_image);
$image_size = $_FILES['image']['size'];
$allowed_img_ext = array("jpg", "jpeg", "png", "bmp");
$ext = pathinfo($up_image, PATHINFO_EXTENSION);
$trimed_img_name = pathinfo($up_image, PATHINFO_FILENAME);
if(in_array($ext, $allowed_img_ext))//check valid file extension
{
if($image_size < 2097152) {
$ren_image = substr($trimed_img_name,0,3)."".substr($title,0,11)."_".date("mj")."_".date("Y")."_".date("His").".".$ext;
$path = "img/".$ren_image;
$update_query = "UPDATE posts SET title = '$up_title', image = '$ren_image', categories = '$up_categories', tags = '$up_tags', post_data = '$up_post_data', status = '$up_status' WHERE id = $edit_id";
}
else{
$img_error = "Please Upload the Image File Size Less than 2 MB";
}
}
else{
$img_error = "Invalid Image File";
}
if(mysqli_query($con, $update_query)){
$msg = "Post has been Updated";
header("refresh:1;edit-post.php?edit=$edit_id");
if(move_uploaded_file($up_tmp_name, $path)){
copy($path, "../$path");
}
}
else{
$error = "Unable to Update Post";
}
} //End

So I removed $up_image = $image; and image = $up_image section from first query now it is working. Thanks for your comment
