Invalid argument supplied for foreach()

[Xtremer360]

I'm not sure why but I'm getting a <b>Warning</b>:  Invalid argument supplied for foreach().

 

 

if (isset($_POST['deleteContentPagesArray'])){

    $contentPageIDs = $_POST['contentPageArray'];

    foreach ($contentPageIDs as $contentPageID) {
    
        $deleteQuery = "UPDATE `manager_site_contentPages` SET `status` = 'Deleted' WHERE `id` =  '".$contentPageID."' LIMIT 1"; 
    
        mysqli_query($dbc,$deleteQuery);
        
        // Delete was sucessful
        $errors = false;
        
        $output = array('errorsExist' => $errors);
    
    }
    
}

$contentPageIDs = !empty($_POST['contentPageArray'])?$_POST['contentPageArray']:array();

 

Should fix your issue. Since POST data is unreliable, it is better to check that you have content you are expecting. If not default it or throw an error to handle it properly.

I'm still getting the same thing.

Then your post variable coming in is not an array. Do a

 

var_dump($_POST['contentPageArray']);

and see what is happening.

string(3) "2,3"

Ok, so the obvious problem is that you do not have an array.

 

$contentPageIDs = !empty($_POST['contentPageArray']) ? explode(',', $_POST['contentPageArray']) : array();

 

Should fix your troubles.
