switch statement help

mayman212 · September 14, 2011

Hi all,

I am creating a switch page which will be acting as more of an index page for the different php files I have in my project. I have seven different pages and, I am a bit stuck as to what the order is and where the codes should go.

I have got this far as is shown below:

<!--PHP Update-->
<?php

$con = mysql_connect("localhost","root","");

if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("project1", $con);

if ($_GET['action']=='delete_ok' and or){

}elseif ($_GET['action']=='edit_ok'){

}


switch($_GET['action']){
   case 'delete_ok':
#########Delete OK Start#################

//echo '<meta http-equiv="Refresh" content="0;URL=switch.php">';
#########Delete OK End #################
   break;
   case 'edit_ok':

   break;

}
?>

<!--HTML-->

<?php

switch($_GET['action']){
   case 'delete';

   break;
   case 'edit';
      echo 'Edit page';
      ?>
      <form action="switch.php?action=edit_ok" method="post">
      <?php
   break;
   default:




      echo "<table border='1'>
      <tr>
      <th>ID</th>
      <th>Date Of Birth</th>
      <th>Gender</th>
      <th>Title</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Address Line 1</th>
      <th>Address Line 2</th>
      <th>City</th>
      <th>Postcode</th>
      <th>Contact No</th>
      <th>Email</th>
      <th>Additional Info</th>
      <th>Action</th>
      </tr>";

      $result = mysql_query("SELECT * FROM project_data");
      while($row = mysql_fetch_array($result)){
        echo "<tr>";
        echo "<td>" . $row['ID'] . "</td>";
        echo "<td>" . $row['Date_Of_Birth'] . "</td>";
        echo "<td>" . $row['Gender'] . "</td>";
        echo "<td>" . $row['Title'] . "</td>";
        echo "<td>" . $row['First_Name'] . "</td>";
        echo "<td>" . $row['Last_Name'] . "</td>";
        echo "<td>" . $row['Address_Line_1'] . "</td>";
        echo "<td>" . $row['Address_Line_2'] . "</td>";
        echo "<td>" . $row['City'] . "</td>";
        echo "<td>" . $row['Postcode'] . "</td>";
        echo "<td>" . $row['Contact_No'] . "</td>";
        echo "<td>" . $row['Email'] . "</td>";
        echo "<td>" . $row['Additional_Comment'] . "</td>";
        echo "<td><a href='switch.php?action=edit&id=" . $row['ID']."'>Edit</a>&nbsp&nbsp<a href='delete_write.php?id=" . $row['ID']."'>Delete</a></td>";
        echo "</tr>";
        }
      echo "</table>";

      echo "<a href='write.php'>Insert</a>";



}

mysql_close($con);
?>

the file names are:

delete_write.php- deletes the data

display.php- displays the data

edit_write.php- editing the info

edit_write_ok.php- edits on the database and shows on display.php

write.php- this is the input page

write_input.php- this inputs the data from write.php into the main database

any help would be much appreciated.

MOD EDIT: code tags added.

You want to use the switch to redirect page?

mayman212 · September 14, 2011

Yes.

voip03 · September 14, 2011

<?
switch ($_GET['action'])
{
case "delete":
	header("Location:delete_write.php"); exit();
	break;
case "'edit_ok'":
	header("Location:edit.php"); exit();
	break;
default:
	header("Location:index.php"); exit();
	break;
}
?>

voip03 · September 14, 2011

default:It's usually a good idea to always include the default case in all your switch statements.

Pikachu2000 · September 14, 2011

When posting code, enclose it within the forum's

 . . .

BBCode tags.

mayman212 · September 14, 2011

any help on where to put the codes for the different pages?

Nodral · September 14, 2011

Use the method that voip has quoted, then create a new file for each page

mayman212 · September 14, 2011

yes but do I use a different case break for each page and do i put where the HTML comment is or above it.

Sorry I have gone completely brain dead.

voip03 · September 14, 2011

When the user submit the form, you want to redirect the page depend on the user selection.

mayman212 · September 15, 2011

yes. when the user has the display page (which is default), I want the links for Insert, delete and edit to redirect to that page and the go back to the list.

thanks.

mayman212 · September 16, 2011

Ive got this far, but I'm now stuck on the edit and delete parts. When I click edit it redirects me to the form but it is blank, I want it to be filled with the record that I clicked the edit button on. And also help on the delete part would also be helpful. Thanks

if ($_GET['action']=='delete_ok'){}elseif ($_GET['action']=='edit_ok'){}

What is the purpose of the above code?

you need to rearrange your logic processing methods.
