Now, this code is an addon code that i have to insert it into the above code to show up the dimensions of the products.

$product = $GLOBALS['ISC_CLASS_PRODUCT']->GetProduct();
$dimensions = array(
     'ProductHeight' => 'prodheight',
     'ProductWidth' => 'prodwidth',
     'ProductDepth' => 'proddepth'
);
foreach($dimensions as $global => $field) {
     if($product[$dimensions] > 0) {
         $GLOBALS[$global] = FormatWeight($product[$field], false);
         $hasDimensions = true;
     }
    else {
         $GLOBALS['Hide'.$global] = 'display: none';
     }
}


if(!isset($hasDimensions)) {
     $GLOBALS['HideDimensions'] = 'display: none';
}

Now when i try to add the addon code to the default code, i get this error:-

Warning: Illegal offset type in /homepages/10/d264080461/htdocs/includes/display/ProductDetails.php on line 10

Please help me guyz because the application company asks me to contact your php developer where as i don't have any programmer with me who could solve this problem and i'm in a urgent need of it. I have a very less knowledge of PHP. So, please help me guys correcting this code.

Thanks in advance

First of all u get a warning and not an error. This means that ur code will continue to run till the end of the script, tough something seems to went wrong.

Getting the illegal offset type - warning comes around when u try to acces an item in an array that is not there. Give me a minute to look into ur code and try to find a solution on why its not working.

Can u enlighten me on what spot exact ur pushing ur addon into ur upper code? So that i can check with the error on what line exact he generates the warning. U can also just paste a new code example.

peddel · February 19, 2009

I think i found the reason of ur warning.

It has to do with the FormatWeight($product[$field], false); function.

Can u give me the code behind this function? Cuz i cant seem to find it

bret_chels · February 19, 2009

Thanks peddel for helping!

This is the exact code where i get this warning. The code in pink color is the code that i pasted.

<?php

[color=pink]$product = $GLOBALS['ISC_CLASS_PRODUCT']->GetProduct();
$dimensions = array(
    'ProductHeight' => 'prodheight',
    'ProductWidth' => 'prodwidth',
    'ProductDepth' => 'proddepth'
);
foreach($dimensions as $global => $field) {
    if($product[$dimensions] > 0) {
        $GLOBALS[$global] = FormatWeight($product[$field], false);
        $hasDimensions = true;
    }
    else {
        $GLOBALS['Hide'.$global] = 'display: none';
    }
}


if(!isset($hasDimensions)) {
    $GLOBALS['HideDimensions'] = 'display: none';
}

Im sorry but i get the idea that u were not the guy who build this code.

It seems that the guys who programmed this knew exactly what he was doing, inserting stuff inside someone elses code is hard, and i should see the compleet project and think about it to find a solution.

UR best shot is contact the guy who made this, since i cannot spare more time on this, im sorry.
