activate and deactivate instead of deletion

[myhope]

hi, all i am new in php developing

i need to know how i could make a user data hidden or inactive to the viewer of my website

without deleting this user data from my database

can i do that using php code?

if yes what is this coding criteria

thanks in advance

You can add another field on your users table named 'activity' where you can flag a user as 'active' or 'inactive.' That way whenever you query the database you just have to "SELECT * FROM users WHERE activity = 'active'" so that it won't show your inactive users.

More info please. As mentioned by Shinehah, a flag field like "activity" set to 0 or 1 (default) would work for most cases, but not knowing the actual use case, it's difficult to say.

here is my code

mysql_connect("localhost","root","");
         mysql_select_db("dbname");
       if($_REQUEST['select'] == "Activate")

      {
      mysql_query("update table1 set status=1 where P_id in $Patient_id");

}
if($_REQUEST['select'] == "Deactivate")

      {
      mysql_query("update table1 set status=0 where P_id in $Patient_id");

}

      $query = "SELECT * FROM `table1`";

      $dd=mysql_query($query);
 ?>

is this true?

Assuming the status column is the active flag you need, just change the last query to be:

SELECT * FROM TABLE1 WHERE status = 1

Urghh. $_REQUEST!

mysql_connect("localhost","root","");
mysql_select_db("dbname");

if($_POST['select'] == "Activate"){
  mysql_query("UPDATE table1 SET status=1 WHERE P_id = $Patient_id");
}
if($_POST['select'] == "Deactivate"){
  mysql_query("UPDATE table1 SET status=0 WHERE P_id = $Patient_id");
}

$query = "SELECT * FROM table1";
$dd=mysql_query($query);

Can't see anything wrong with the above now. As long as $Patient_id is an integer. Also ensure that when you set the variable, it had the same case, i.e. $Patient_id and not $patient_id - they are treated as 2 different variables in php.

You can test to see if an update query has been completed successfully:

if($_POST['select'] == "Activate"){
  mysql_query("UPDATE table1 SET status=1 WHERE P_id = $Patient_id");
  echo "UPDATE table1 SET status=1 WHERE P_id = $Patient_id"; //check query
}
if($_POST['select'] == "Deactivate"){
  mysql_query("UPDATE table1 SET status=0 WHERE P_id = $Patient_id");
  echo "UPDATE table1 SET status=0 WHERE P_id = $Patient_id"; //check query
}

if(mysql_affected_rows()>0){
  echo "table updated";
}else{
  echo "table not updated";
}

Purely for testing.

i am unable to understand that how we will store the status (1 or 0) in our database?what should be the type of the status in the database?

maybe tinyint, set to 1 digit, default = 0 or 1 if you want

What do you mean by activate and deactivate on php mysql?
