HTML of the buttons:

<input type="image" src="delete.gif" name="delete">
<input type="image" src="edit.gif" name="edit">

Then in the form handling script:

if(isset($_POST['delete_x']) && isset($_POST['delete_y']) {
        // delete
}

if(isset($_POST['edit_x']) && isset($_POST['edit_y']) {
        // edit
}

If every browser was standards compliant, you could use:

<input type="image" src="delete.gif" name="action" value="delete">
<input type="image" src="edit.gif" name="action" value="edit">

switch($_POST['action']) {
        case 'delete':
                // delete
                break;
        case 'edit':
                // edit
                break;
}

setcookie( "sess_key",$key,0,"/","." . str_replace(
"www","",$_SERVER["SERVER_NAME"] ),0 );

Does that look right?

Thanks!

No.

if $_SERVER["SERVER_NAME"] == 'www.domain.com'

"." . str_replace("www","",$_SERVER["SERVER_NAME"] )

will give you "..domain.com"

attached mail follows:

ok I see how that could be an issue.

Here is my big problem that I have not been able to figure out.

I have a client website that I am trying to fix

1. it has sessions in database, and uses set cookie

2. I can login with firefox/netscape/mozilla just fine

3. I cannot login with any version of IE

4. this is also by going to domain.com or www.domain.com, neither work

any ideas?

LG> folder. Then if the site is moved and they aren't using an

LG> 2. set_include_path

LG> 3. An include file in every directory to set the include path.

This will set the include path just before the document root:

if(isset($_SERVER["SCRIPT_FILENAME"])){
        $root = $_SERVER['SCRIPT_FILENAME'];
        //echo "Root: $root<br>";
        
        $script = $_SERVER['SCRIPT_NAME'];
        $document_root = str_replace($script,'',$root);
        //echo "Document root: $document_root<br>";
        
        $base = basename($document_root);
        //echo "Base: $base<br>";
        
        $include = str_replace($base,'include',$document_root);
        //echo "Include: $include<br>";
        
        $os = strtolower(PHP_OS);
        //echo "OS: $os<br>";

        $lk = ':';
        $org_include = ini_get("include_path");
        if(preg_match('/^win/i',$os)) $lk = ';';
        
        ini_set("include_path",$include.$lk.$org_include);
        //echo "Include: ".ini_get("include_path")."<br>";
}

you could do:

echo '<table border="1">'.LF;

here is a description of a simple ordering mechanism, hope it gives you
an idea how to proceed:

1. output a table that reflects the current order.
    each row should have (at least) 2 links: 'move up' & 'move down',
    the links should have GET params for the direction you want to the
    position to change to and the id of the item whose position you want to
    change.

2. if a user clicks on one of those links do the following processing:

    MOVE DOWN:
        1. determine the selected items current 'position'
         2. find the item whose 'position' is the next greatest (value) after
            the selected items 'position'
        3. if an item with greater 'position' is found then do:
                a, update selected items position with position value of item found
                    in step 2
                b, update the 'position' of the item found in step 2 with the 'position'
                   value of the selected item.
    MOVE UP:
        1. determine the selected items current 'position'
         2. find the item whose 'position' is the next lowest (value) after
            the selected items 'position'
        3. if an item with lesser 'position' is found then do:
                a, update selected items position with position value of item found
                    in step 2
                b, update the 'position' of the item found in step 2 with the 'position'
                   value of the selected item.

3. go back to step 1. (output a table!)
