I have an issue where I need to be able to use check boxes

  • 0

I have an issue where I need to be able to use check boxes in order to delete and modify data in a mysql database.

What is the most efficient way of being able to use multiple submit buttons to either insert data based on what the user types into the text boxes, delete based on the check boxes selected, and modify based on the check boxes selected.

Here is the code I have so far:

 <?php 
$host       = "localhost";
$user       = "root";
$pass       = "";
$dbName     = "ticket_history";
$table_name = "ticket_history";

################ Connect to the Database and SELECT DATA ####################################
$conn = mysql_connect($host, $user, $pass) or die ("Unable to connect");
mysql_select_db($dbName);
$query = "SELECT Auto,Date,Ticket_Number,Description,Result FROM $table_name";
$result = mysql_query($query);
$count=mysql_num_rows($result);

    I would take the insert and delete code and put it on top of the main file instead of having them into files. the simplest way would be to submit the form to itself and based on the submit button clicked run the code block

    if($_POST['create']){
  // insert code
}
elseif($_POST['delete']){
  // delete code
}

    continue the logic of if/else/elseif to handle all the cases. This strikes me as the simplest way to get done what you want to do.

    Edit:
    Not sure but seems like you are handling the $_POST[‘create’] etc after the HTML code. You should always do that sort of processing BEFORE the html rendering and even before the query to get the records you want to display, this way your get query will always bring up to date results.
