undefined index error

jason1987

I keep getting the undefined index error on the bottom two rows of my code simparent and equtype - the other two work fine yet there is no difference in my code. equtypeid is even from the same table as the top two

Expand|Select|Wrap|Line Numbers

 
$equid=$HTTP_POST_VARS['equid'];

$fromuserid=$HTTP_POST_VARS['fromuserid'];

$simparent=$HTTP_POST_VARS['simparentid'];

$equtype=$HTTP_POST_VARS['equtypeid'];

these are then used in an if statement

Expand|Select|Wrap|Line Numbers

 
if ($simparent == !'Null')

{

    if($equtype == '8')

    {

         $simins = "UPDATE itsiminfo SET simparentid=NULL WHERE itsiminfo.equid='$equid'";

         echo $simins;

        //$resultsimins = mysql_query($simins);                     // Removes link between sim card and mobile/3G - only from SIM though not via mobile or 3G

    }
 
    if($equtype == '7' || '4')

    {

        $simins2 = "UPDATE itsiminfo SET simparentid=NULL WHERE simparentid='$equid'";

        $resultsimins2 = mysql_query($simins2);                 //Removes link between Mobile/3g and sim - from through mobile or 3g

    }

}

anyone help??

First you should arrange your IF blocks in a propper way. I have some doubts with your conditions:
could you please take a look at on this.

<?php

$simparent = 'Null'; // change this and check

$equtype = '4'; // change this and check
 
if($simparent != 'Null'){

echo 'match found $simparent';

}
 
echo '<br>';
 
if(($equtype == '7') || ($equtype == '4')){

echo 'match found $equtype';

}

?>
