Submit button dont work

[kristian_gl]

preview.php:

 

 <form id="form100" name="form100" method="POST" action="preview.php">

             <input type="submit" name="back" id="tilbake" value="Back" />
             <input type="submit" name="finish" id="lagre" value="Finished" />
             <input type="submit" name="publish" id="publiser" value="Publish" />
             </form>
             <br />
       

         

   

<?php
        $finish= $_POST['finish'];
	$back= $_POST['back'];
	$publish= $_POST['publish'];



	if (isset($finish))
	{
	setcookie("navn_cookie", "", time()-3600);
	header('Location: http://stud.aitel.hist.no/~oddl/admin/admin.php');
        }
	elseif (isset($back))
	{
	header('Location: http://stud.aitel.hist.no/~oddl/admin/leggtilspm.php');
	}
	elseif (isset($publish))
	{
	$drop_table = "DROP TABLE `svar`";
	mysql_query($drop_table);
	$create_table = 'CREATE TABLE `svar` ('
        . ' `id` INT(4) NOT NULL AUTO_INCREMENT PRIMARY KEY'
        . ' )'
        . ' ENGINE = myisam;';
	mysql_query($create_table);

	header('Location: http://stud.aitel.hist.no/~oddl/admin/undersokelse.php');

	}

?>		

 

When I click on any of the submitbuttons, the page just refreshes itself, and doing what I've haved specified in the if-loop

Isset checks if the variable has been set or exists, you have set each variable to exist just above the if statement that checks it, it will always return true - and execute. Use if(isset($_POST['finish'])), and if(isset($_POST['back'])) instead.

 

Also,

I would use hard links instead though, rather than extra submit buttons (since you don't need to submit data unless your publishing), just like:

 

 <form id="form100" name="form100" method="POST" action="preview.php">

            <a href="preview.php?action=back">Back</a>
            <a href="preview.php?action=finish">Finished</a>
             <input type="submit" name="publish" id="publiser" value="Publish" />
             </form>
             <br />

then just change this

   

<?php
	if (isset($_GET['finish']))
	{
	setcookie("navn_cookie", "", time()-3600);
	header('Location: http://stud.aitel.hist.no/~oddl/admin/admin.php');
        }
	elseif (isset($_GET['back']))
	{
	header('Location: http://stud.aitel.hist.no/~oddl/admin/leggtilspm.php');
	}
	elseif (isset($_POST['publish']))
	{
	$drop_table = "DROP TABLE `svar`";
	mysql_query($drop_table);
	$create_table = 'CREATE TABLE `svar` ('
        . ' `id` INT(4) NOT NULL AUTO_INCREMENT PRIMARY KEY'
        . ' )'
        . ' ENGINE = myisam;';
	mysql_query($create_table);

	header('Location: http://stud.aitel.hist.no/~oddl/admin/undersokelse.php');

	}

?>

Works for me.  What I would do however is to use the same name for the submit button, but only change the value

 

<input type="submit" name="submit" id="tilbake" value="Back" />
<input type="submit" name="submit" id="lagre" value="Finished" />
<input type="submit" name="submit" id="publiser" value="Publish" />

 

Then in the preview.php

 

$selection = $_POST['submit'];

if ($selection == 'Back') {

...

} elseif ($selection == 'Finished') {

.....

} elseif ($selection == 'Publish') {

......

}
