[SOLVED] Editing using switch/case

careym1989 · December 23, 2008

Hello again! Got another question. I'm using switch and cases to change the command. Examples of the commands are: view, add, edit, delete. Everything else is working perfectly, but I'm having trouble with the 'edit' case. Here's the code:

case 'edit':
      
$submitted == $_REQUEST['submitted'];
    
    if($submitted=="1") {
    
    $text == $_REQUEST['text'];
    $url == $_REQUEST['url'];
    $id == $_REQUEST['id'];
    
include("MySQL_Connect.php");
$sql = "UPDATE navbar SET text='$text', url='$url' WHERE id='$id'";
$result = mysql_query($sql);  

if($result) {
    echo mysql_affected_rows();
    echo " records successfully updated.";
    exit;
    } else {
    echo "Error encountered. Try again.";
    }
    
    } else {
    echo "Please fill out the form above and click \"Submit.\"";
    }
?> 
    
</p>

<p>
<?php

    $id = $_REQUEST['id'];
    
include("MySQL_Connect.php");
$sql = "SELECT * FROM navbar WHERE id='$id'";
$result = mysql_query($sql);  

while($info = mysql_fetch_assoc($result))  
{
    ?>

<form name="nb" method="post" action="http://www.blackandwhitecms.com/Control_Panel/Navigation_Bar.php?cmd=edit&id=<?php echo $id ?>">
  <table width="476" border="0" cellspacing="0" cellpadding="0">
    <tr>
      <td width="112">Link Title</td>
      <td width="364"><label>
        <input name="text" type="text" id="text" size="40" value="<?php echo $info[text] ?>" />
      </label></td>
    </tr>
    <tr>
      <td>Link URL</td>
      <td><label>
        <input name="url" type="text" id="url" size="40" value="<?php echo $info[url] ?>" />
      </label></td>
    </tr>
  </table>
  <p>
  	<input type="hidden" name="submitted" id="submitted" value="1" />
    <input type="hidden" name="id" id="id" value="<?php echo $info[id] ?>" />
    <label>
      <input type="submit" name="Submit" id="Submit" value="Submit" />
    </label>
  </p>
</form>

<?php } 
  
  
    break;

The problem is the $submitted if statement isn't working properly. Currently, I change the information that's in the fields and hit "Submit" and the fields change back to what they are currently in the table.

Help would be much appreciated! I've tried a couple of different approaches, but none have worked.

Thanks,

C

Try some debugging (should be removed once working).

$result = mysql_query($sql) or die(mysql_error() . "<br />$sql<br />");

Thanks for the speedy reply. Here's my code:

	$submitted == $_REQUEST['submitted'];
    
    if($submitted=="1") {
    
    $text == $_REQUEST['text'];
    $url == $_REQUEST['url'];
    $id == $_REQUEST['id'];
    
include("MySQL_Connect.php");
$sql = "UPDATE navbar SET text='$text', url='$url' WHERE id='$id'";
$result = mysql_query($sql) or die(mysql_error($sql));

Unfortunately, it's not even debugging. I put your code first and then tried the above code. Still, nothing is appearing.

The case I'm having trouble with is case 'edit.' Delete, add, view are no problem.

Quick bump. Thanks!

Mikedean · December 23, 2008

Is there any reason why on the 'edit' case you are using '$_REQUEST'? Try changing it to the way adding handles it.

$submitted = $_POST['submitted'];

if ($submitted == 1) {

careym1989 · December 24, 2008

Got it working. Seems the $_POST did it. Not sure why -- I've use $_REQUEST for almost everything, except for $_GET's. It seems to work as $_POST too.

Thanks for the help, though! Took me a day to get that working!
