[SOLVED] Need 2 buttons on a form

[daalouw]

I would appreciate any assitance you can offer please.

 

I have data in a form that needs to respond to 1 of 2 buttons.  There are 2 options... Update or Delete.  Update will take whatever is typed and update the MySQL table.  Delete will just delete the data from the MySQL table.  I send all form responses to my index.php page and then decide which PHP source to include based on the name value pair I send it from my forms.

 

Relevent Index.php code is below:

 

<?php

  if (!isset($_REQUEST['content']))

      include("main.inc");

  else

  {

  $content = $_REQUEST['content'];

  $nextpage = $content . ".inc";

  include($nextpage);

  }

?>

 

However, I am unable to detect which button was selected (Update or Delete) on the original form.

 

Here is my code:

echo "<form action=\"index.php\" method=\"post\" target=\"_self\">";

echo "<strong>Title *</strong><br /><input type=\"text\" size=\"45\" value=\"$title\" name=\"title\"><br /><br />";

echo "<strong>News article *</strong><br /><textarea rows=\"5\" cols=\"50\" name=\"article\">$article</textarea><br /><br /><br />";

echo "<input type=\"submit\" value=\"Update\">";

echo "<input type=\"hidden\" name=\"content\" value=\"updatenews\">"; 

echo "<input type=\"submit\" value=\"Delete\">";

echo "<input type=\"hidden\" name=\"content\" value=\"deletenews\">";

echo "</form>";

 

In the code above, no matter what I click, it always goes to deletenews sicen thaty is the last hidden type definition.  I do not know how to differentiate between the 2 buttons.  I have seen other examples on how to do this but none of them use the index.php model where I am sending the 'content' and 'value' name value pair.

 

Any help is much appreciated.

I think you will need to change the name of one of the buttons.

 

name=\"content\"

name=\"Delete\"

Thank you for yoru quick response. 

 

If I change the name to Delete as you suggest, how will control be handed to my code to handle the delete function via the Index.php model I am using?

[peranha]

<?php
   if (isset($_POST['content'])) {
      //  Stuff here if update is clicked
   }
   elseif (isset($_POST['Delete'])) {
      //  Stuff here if delete is clicked
   }
   //  Rest of the page goes here.
?>

Get rid of the hidden fields and give the submit buttons the same name, then you can test to see the value of the submit button:

<?php
echo '<form action="index.php" method="post">';
echo '<strong>Title *</strong><br /><input type="text" size="45" value="' . $title .'" name="title"><br /><br />';
echo '<strong>News article *</strong><br /><textarea rows="5" cols="50" name="article">' . $article . '</textarea><br /><br /><br />';
echo '<input type="submit" value="Update" name="submit">';
echo '<input type="submit" value="Delete" name="submit">';
echo "</form>";
?>

Thank you for your reply Ken.

 

I am still rather new to PHP/HTML... if I make the change as you suggested, how do I then execute the relevant delete or update code I need to via index.php ?  Index.php is expecting 'content' to determine the next code to execute.

[daalouw]

Peranha, if I look at your suggestion of changing the name, how will index.php know when to display main.inc as the default page if no 'delete' or 'conent' info exists.

You can check the value of the submit button instead:

<?php
if (isset($_POST['submit'])) {
   switch ($_POST['submit']) {
      case 'Update':
//
//           code for update here
//
          break;
      case 'Delete':
//
//           code for delete here
//
          break;
   }
}
?>

Ken, if I check on the submit name, then all my regular navigation bars (menu) won't work because they all use 'content' in the href ? i.e. .../index.php/content=newpage.inc.

 

I have really been breaking my brain over this... every possible solution I come up with breaks something else.

[kenrbnsn]

No, you can program your scripts anyway you need to so they work.

 

When checking for values passed on the URL, you need to check the $_GET array:

<?php
if (isset($_GET['content'])) {
//
//   code here
//
}
?>

Ok, this looks like it may work... is this what you are proposing for index.php?

 

First check content, if not there, check submit button, if not there, execute default page.

 

<?php

  if (isset($_GET['content']))

  {

      $content = $_GET['content'];

      $nextpage = $content . ".inc";

      include($nextpage);

  }

  elseif (isset($_POST['submit']))

      {

      switch ($_POST['submit'])

{

        case 'Update':

            include(updatedata.inc);

            break;

        case 'Delete':

            include(deletedata.inc);

            break;

        }

      } 

  elseif

      {

      include("default.inc");

      }

?>

Unfortunately I have several screens with DELETE and UPDATE options, so non of the solutions discussed here will work for me, but that is because of my specific scenario.  I will just havwe to create separate UPDATE and DELETE forms for each funtion.  Sucks!!

 

I'm going to mark this topic as complete though.

 

Sincerely.
