    MySQLi stmt issue

    FORM

    PHP Code:
    <?php
    if($_POST['submit']){
        
    $section mysqli_prep($_POST['table']);
        
    $linkid mysqli_prep($_POST['linkid']);
        
    $title mysqli_prep($_POST['title']);
        
    $des mysqli_prep($_POST['des']);
        
    $date mysqli_prep($_POST['date']);
        if(isset(
    $_POST['facebook'])){$facebook mysqli_prep($_POST['facebook']); } else { $facebook NULL; }
        
        
    $sql "INSERT INTO ? (
                `linkid`, `title`, `description`, `date`, `facebook`
                ) VALUES (
                ?, ?, ?, ?, ?
                )"
    ;
        
    $stmt mysqli_stmt_init($connect);
        
    mysqli_stmt_prepare($stmt$sql);
        
    mysqli_stmt_bind_param($stmt'sissss'$section$linkid$title$des$date$facebook);
        if(
    mysqli_stmt_execute($stmt)){
            
    // Success!
            
    $display_message "<h6 class=\"displaymessage\">Ministry news article created successfully!</h6>\n";
        }else{
            
    // Failed!
            
    $display_message "<h6 class=\"displaymessage\">Ministry news article creation failed.</h6>\n";
            
    $display_message "<h6 class=\"displaymessage\">".mysqli_error($connect)."</h6>\n";
        }
        
    mysqli_stmt_close($stmt);
    }
    ?>
    Returns...

    You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '? ( `linkid`, `title`, `description`, `date`, `facebook` ) VALUES ( ?, ' at line 1
    Is it possible that the selected table cannot be a (?) value? I have done this no problem with basic sql queries in the past...

    Yeah, I don't think you can use place-holders for anything except literal values. You'll need to use PHP variables concatenated (or interpolated) there, I'm afraid -- which means if they come from an external source you'll need to do some sort of validation and/or sanitation of them.

    PS: another option would be to create a stored procedure, to which you could pass a parameter for the table name, I think.
