I think the problem is related to the Dynamic Dropdowns.

I have created a number of pages with DataAssist. The Results Page works fine. However, on the Update Page I have modified two List boxes with Dynamic Dropdown array and a behaviour. When attempting to post the data to the database the following is displayed:
Notice: Array to string conversion in /Applications/XAMPP/xamppfiles/htdocs/wpc/admin/news_update.php on line 93
Notice: Array to string conversion in /Applications/XAMPP/xamppfiles/htdocs/wpc/admin/news_update.php on line 93
Notice: Array to string conversion in /Applications/XAMPP/xamppfiles/htdocs/wpc/admin/news_update.php on line 93

The contents of line 93 are as follows:
$WA_fieldValuesStr = "".((isset($_POST["headline"]))?$_POST["headline"]:"") ."" . $WA_AB_Split . "".((isset($_POST["author"]))?$_POST["author"]:"") ."" . $WA_AB_Split . "".((isset($_POST["detail"]))?$_POST["detail"]:"") ."" . $WA_AB_Split . "".((isset($_POST["category"]))?$_POST["category"]:"") ."" . $WA_AB_Split . "".((isset($_POST["date_added"]) && $_POST["date_added"]!="" )?date("Y-m-d H:i:s", strtotime($_POST["date_added"])):"") ."" . $WA_AB_Split . "".((isset($_POST["active"]))?$_POST["active"]:"") ."" . $WA_AB_Split . "".((isset($_POST["news_type"]))?$_POST["news_type"]:"") ."" . $WA_AB_Split . "".((isset($_POST["maincategory"]))?$_POST["maincategory"]:"") ."" . $WA_AB_Split . "".((isset($_POST["added_id"]))?$_POST["added_id"]:"") ."" . $WA_AB_Split . "".((isset($_POST["add_ip"]))?$_POST["add_ip"]:"") ."";
I assume that the problem arises from the $WA_BA_Split but I don't know.
Any ideas would help. I am using Dreamweaver CS6 and Databridge Version 1.2.4

My guess is that one of those fields is a checkbox group or multi-select list and is being posted as an array. Can you attach the actual page so I can open it it Dreamwweaver? That might help me track down the problem.

I've uploaded news_update.php which is one of the pages causing the error.
There are three 'lists' on the page but I assumed only the value of the selected item would be passed.

You have a form field name="news_type[]". If it is a single select list the field name should be: name="news_type"

That is the issue. Fields named with brackets are automatically submitted as an array.

Thanks Ray, that solved the problem. I'm not sure how the [] got into the name, but it's something I'll look out for in the future.

Once again thanks for your prompt action.
