Hello,

Try declaring the array:
$example = array();
$example[] = ‘somecontent’;
$example[] = ‘somemorecontent’;

I also am getting this error. Unfortunately I don’t understand any of what has been said above. Here is my error – how to correct?

Warning: Cannot use a scalar value as an array in

I realized that I was getting that same error because I was dumping some form data into an array via: $cart['data'] = $_POST; Besause the $_ vars are of different types it would not allow me to add new varaibles to the $cart['data'] array, like so: $cart['data']['total'] Then I changed the code to: foreach($_POST as $k => $v) $cart['data'][$k] = $v; That made everything work just fine.

Code example removed so here it is again. This will cause the same error.

$foo=0;//int
$foo[]=1;

The error comes because you are trying to append an array value to a variable. PHP will automatically typecast a variable so you don’t have to declare it’s type but it wont re typecast.

will cause this error.

I am having a similar error in my site and I cannot figure out how to fix it. I get a “Warning: Cannot use a scalar value as an array in …/query.php on line 2678″

The error is intermittent and I cannot figure out what to do to fix it. I tried adding your code in the top, but nothing seemed to change.

I looked at doug b’s option, but I would rather not edit the core wordpress files if I can avoid it.

Any ideas? Or other places I could look? I’m really stuck on this one…

I also had this problem. It’s due to WordPress setting PHP’s error reporting level more strict than the default settings on your server. Most servers disable warnings since they’re not critical errors (won’t cause your script to die). WordPress overrides these settings, and it does it in at least 7 locations. Get a decent editor like jedit and do a find in directory for the php function “error_reporting”. Comment out every one.

There is absolutely no reason for WordPress to do this, other than to assume that they’re the only thing you have running under PHP on that server. It’s bad form in my book.
