sql查询错过了数据库内的两列

Question

Ok Hi I have a slightly weird problem that I cannot figure out mysql query posts the uniq_id in the title column instead of its own and the title, blurb and uniq_id end up empty.

to start off with i create a uniq_id in php and then assign this to be a value within a hidden field within a form this is the code:

  $uid = uniqid();
  /*echo $uid;*/

  echo " <input type=\"hidden\" value=\"$uid\" name=\"Uniq_id\"/>";

this is then posted using the form submit button,

then on the next page $_POST catches all of the values and turns them into variables this is the code for that:

$Title = $_POST['Title'];
$Blurb = $_POST['Blurb'];
$Subject = $_POST['cat'];
$Section = $_POST['typ'];
$Principle = $_POST['princ'];
$Verify = $_POST['verification'];
$Career = $_POST['career'];
$Job = $_POST['job'];
$Uniq_id = $_POST['Uniq_id'];

the variables are then used within this page within the sql query bellow which is ment to post these values into the database the function below is the one that is run when you click the submit button

    public function addNewRecord($Subject, $Section, $Principle, $Job, $Career, $Title, $Blurb, $Uniq_id)
            { 
                $sql = "INSERT INTO `careersintheclassroom`.`media` (`media_id`, `subject_id`, `section_id`, `principle_id`, `title`, `blurb`, `verified`, `media_uniqid`) 
                       VALUES (NULL, '".$Subject."', '".$Section."', '".$Principle."', '".$Title."', '".$Blurb."', '0', '".$Uniq_id."')"; // sql query 

                 return mysql_query($sql, $this->conn); // connection to database and also getting the results from query

  }

when it posts the values to the page with this function it prints the values on a page showing me all the values this is one of them.

INSERT INTO `careersintheclassroom`.`media` (`media_id`, `subject_id`, `section_id`, `principle_id`, `jobrole_id`, `career_id`, `title`, `blurb`, `verified`, `media_uniqid`) 
    VALUES (NULL, '1', '1', '1', '2', '2', 'Title1', 'Blurb1', '0', '532061df6b80d');File is valid, and was successfully uploaded. 

Now in the database it does something strange it posts in the first 4 values correctly then it inserts the Uniq_id into the title doesn't insert anything into blurb then put the correct value into verified and then leave the last column blank to,

Answer 1

What is the type of the verified field?

Try this, notice the quotes around 0 :

VALUES (NULL, '".$Subject."', '".$Section."', '".$Principle."', '".$Title."', '".$Blurb."', '"0"', '".$Uniq_id."')"; // sql query 

Answer 2

Hi Guys thanks for all of the answers I have figured out what the problem is I have figured out that my syntax for the mysql query was wrong I used phpmyadmin to create the php code and then altered it to fit the functions but this was wrong the code i was using was:

 $sql = "INSERT INTO `careersintheclassroom`.`media` (`media_id`, `subject_id`, `section_id`, `principle_id`, `title`, `blurb`, `verified`, `media_uniqid`) 
 VALUES (NULL, '".$SUBJECT."', '".$SECTION."', '".$Principle."', '".$Title."', '".$Blurb."', '0', '".$Uniq_id."')"; 

instead the correct code that it should be is

$sql = "INSERT INTO media (media_id, subject_id, section_id, principle_id, title, blurb, verified, media_uniqid)
VALUES ('NULL', '".$Subject."', '".$Section."', '".$Principle."', '".$Title."', '".$Blurb."', '0', '".$Uniq_id."')"; 

As you can see the columns have got `` around them this is wrong so removing them inserts the details correctly into the columns

Thanks for everything guys you have helped a lot.

Answer 3

Is it possible that the "title" column is configured to insert a guid for every row insert. Check the column definition for title. Also did you verify that the Blurb and media_uniqueid columns values passed on to the function to be inserted are not null/blank for some reason.. Just checking..
