Undefined index: checkuser?

Undefined index: checkuser?

Hi,

I wonder if you can help! I have an error appearing on my index page that I have never seen before and its appearing in the username login field. This is the message appearing...

<br /><b>Notice</b>: Undefined index: checkuser in <b>M:\xampp\htdocs\midas2demo\iphone\m_login.php</b> on line <b>350</b><br />.

Now the strange thing is that I have this page online and it has worked fine for over a year. I downloaded the web page to add more functions to it and the message just appears when I run the file on my localhost. If I clear the message and login. It logs me into the site but an error message appears on the next page... Notice: Undefined variable: totalRows_Recordsetsearchcustomers in M:\xampp\htdocs\midas2demo\iphone\m_schedule.php on line 179

Once again this has always worked properly, and does online I have dataAssist 2.0.6 Utility and Universal Email 4.0.1 Suite installed

I have tried the above with dataAssist switched off and the same happens. I copied the working file from online put it straight into my htdocs folder and the error still appears. Do you guys have any idea what it may be? I'm using xampp and everything is working OK. I'm stumped.


Thanks in advance


John

the "error" is not really an error. it is a Notice. it means that you have code that is referencing variables that don't exist.

it may be that the variables being referenced don't get created when the page initially loads, but do get created at another time.

the Notices don't show on the live server because the error level on the live server does not show notices.

send a copy of the pages so i can see the code at those lines to tell why the Notices are happening and whether or not the are problems or can be ignored.

Hi Jason,

Thanks for responding. From what your saying then, it sounds like apache/xampp may be allowing the error messages to be displayed.

I will have a look into it. I have attached the 2 php files for your attention.

Thanks again Jason

Hi Jason,

After further investigation I found out that the latest version of xampp has the php error reporting on strict as well as show all errors. The solution was to edit the .ini file to the following...

;error_reporting = E_ALL | E_STRICT
error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR

The errors are no longer showing, so thanks again

the first error:
<br /><b>Notice</b>: Undefined index: checkuser in

is caused by this code in the login page:

<input name="username" type="text" class="style7" id="UserName" value="<?php echo $_SERVER['checkuser']; ?>" size="10" maxlength="30" />

you are using the variable $_SERVER['checkuser'] as the value, there is no such variable in the $_SERVER supper global.

you should set the value of the username element to be blank.

the second error is happening because code is out of order on the m_schedule.php page.


the following code block at lines 165 - 179:

php:
$queryString_Recordsetsearchcustomers = "";

if (!empty($_SERVER['QUERY_STRING'])) {
  $params = explode("&", $_SERVER['QUERY_STRING']);
  $newParams = array();
  foreach ($params as $param) {
    if (stristr($param, "pageNum_Recordsetsearchcustomers") == false && 
        stristr($param, "totalRows_Recordsetsearchcustomers") == false) {
      array_push($newParams, $param);
    }
  }
  if (count($newParams) != 0) {
    $queryString_Recordsetsearchcustomers = "&" . htmlentities(implode("&", $newParams));
  }
}
$queryString_Recordsetsearchcustomers = sprintf("&totalRows_Recordsetsearchcustomers=%d%s", $totalRows_Recordsetsearchcustomers, $queryString_Recordsetsearchcustomers);




needs to come after the following line at 216:

php:
$totalRows_Recordsetsearchcustomers = mysql_num_rows($Recordsetsearchcustomers);

Thanks

A big thanks for that Jason :)

I'm pretty sure now the 'undefined variables' have come to light that their are a good few floating round my site.

Mind you the system works, customers are not complaining so that's a good thing.

Cheers
