mysql查询不再起作用

Question

I am trying to make it so that you can upload a ppt and it will split into a pdf for each slide. i have already made a shell script to do the ppt splitting and that works, however i am having trouble with my sql query to update my database. I had it working at one point and then all of a sudden it stopped working, not sure what i did to mess it up but it looks fine to me. Here is some of the code:

if(isset($_POST['title'])){

$admin_id = $_SESSION['user_id'];
$name = $_POST['title'];

if(isset($_FILES["file"]["name"]) && !empty($_FILES["file"]["name"])){
    $fname = $_FILES["file"]["name"];
    $tmp_name = $_FILES["file"]["tmp_name"];
    $dir = "powerpoints/".$name;
    $ispdf = "1";
    echo $tmp_name."----------------".$dir;

    echo $admin_id.':'.$name.':'.$dir.':'.$ispdf;

    $query = mysql_query("INSERT INTO problem (admin_id,topic,image,is_pdf) VALUES ('$admin_id','$name','$dir','$ispdf')");
    //$output = shell_exec('mkdir '.$dir);
    //echo $output;
    if($query && move_uploaded_file($tmp_name, $dir.$fname)){
        //$cmd = 'importppt.sh '.str_replace(".pdf", "", $name);
        $message = "Powerpoint uploaded";
    }elseif($query){
        $message = "move_uploaded_file() Failed";
    }else{
        $message = "Database Error";
    }`

when i try to use the script Database Error is printed which means it skipped over "elseif($query)" also note that there are more columns in my database that i am not updating, however it should just leave them blank for the new entry like it has before it stopped working. all of the names are spelled correctly and the data being put into the query is printed correctly by my echo statement

Update your Query For testing

error_reporting(-1) ;
$query = mysql_query("INSERT INTO problem (admin_id,topic,image,is_pdf) VALUES 
('admin_id','name','dir','ispdf')");

$temp = false;
if(move_uploaded_file($tmp_name, $dir.$fname)){
    $temp = true;
}

if($query && $temp){
    $message = "Powerpoint uploaded,";
}
else if($query){
    $message = "Problem Find In your TITLE, Or Duplicate Data, OR Use mySqli";
}else if(!$temp){
      $message = "Problem Find In your mov directory, Check manually";
}
else{
        $message = "Hope This Else Will not work";
}
