How to avoid Resource_ID Error ?

Posted by pagalreddy (pagalreddy), 11 October 2005
$quMenu = ociparse($link, "select      OrgID, MenuPosition, DisplayText, LinkDestination,
                                               TargetSpec, IndentAmount
                             from      CmtMenu
                             where      OrgID = 2
                             order by MenuPosition");
     $myresult = ociexecute($quMenu)or ("die Unable to obtain menu items - error ".ocierror());;
     while($result=ocifetch($quMenu))      
     {
           $stDisplayText = ociresult($quMenu, "DisplayText");                              //what users see
           print("DisplayText =".$Displaytext);
           print("quMenu =".$quMenu);
           $stLinkDestination = ociresult($quMenu, "LinkDestination");            //something.php
           $stTargetSpec =ociresult($quMenu, "TargetSpec");                              //where to put it (mainFrame ...)
           $siIndentAmount = ociresult($quMenu, "IndentAmount");                        //menu text indent
           switch ($siIndentAmount)
           {

When I try to Open the page, Near Print its giving me Notice: Undefined variable: Displaytext in D:\inetpub\wwwroot\CMT\cm_menu.php on line 43
DisplayText =quMenu =Resource id #6  
Line 43 is the Print line

That's fair enough ... at least in the snippet of code you've posted. It means that you're prining out a variable that hasn't been assigned any value.   It's "just" a notice - PHP will carry on anyway and print nothing at this position.

Footnote for other readers - in PHP you can control the level at which messages are displayed, and the default is that warnings such as the one described in the post are NOT flagged.

It's gpong to return a false value if it fails, do you can check it with an if
