$wpdb->insert not working. No Error Msg

Got the lower portion here sorted, but now there's an issue when it inserts the record. I have the `NULL` value for `file` formatted as `%s` for string, but it's not inserting `NULL` it's inserting `[BLOB - 0B]`. The column format in the mySQL table is `longblob`. Any ideas?
_____________________________________________________
this is my first time using `$wpdb->insert` and it looks like I've missed something.

Here's the loop I'm trying to use. There are currently 2 timestamps in the array.

for ( $i = 0; $i < count($timestamps); $i++ ) {
$working_time = $timestamps[$i];
$working_form = $formnames[$i];

$status_data = array(
'submit_time' => $working_time,
'form_name' => $working_form,
'field_name' => 'lead_status',
'field_value' => 'new',
'field_order' => 10001,
'file' => NULL
);
$status_data_types = array(
'%f',
'%s',
'%s',
'%s',
'%d',
'%s'
);

$result = $wpdb->get_results("SELECT field_value FROM ".$leadtable." WHERE submit_time = ".$working_time);

if(!$result) {
$insert = $wpdb->insert($leadtable, $status_data, $status_data_types);
if( !$insert ) {
echo 'didn\'t work';
}
}
}

I know that `$working_time` and `$working_form` are both set properly. `$working_time` is a long float like `1387175380.9600` and `$working_form` is a string.

Nothing is being returned, even by the `if( !$insert )` check so I'm guessing it's erring somewhere before that point. I know that `if( !$result )` will return true because that data does not exist yet.

Found the issue. The get_results query was failing due to a missed period. My HS English teacher was right... a missed period can be a HUGE problem!

Maybe your config hides error showing. Have you tried `$wpdb->print_error();`?

If you want to get the last error and last query you can use this properties of **$wpdb** object:

$wpdb->last_error

will show you the last error, if you got one.

$wpdb->last_query

will assist you with showing the last query (where the error occurred)

I hope this will help you out.

One of the columns inputs may be larger than the column is.
Wordpress detects this and will not even send the query to the DB.

The Diff there shows a patch for wp-db you can put in to get more information in the last_error message so it will not be empty.

Hopefully, you have defined the global variable `$wpdb`.

If your `$wpdb` is not working, and also not showing any error then you must try these three steps.

1. Print your error using with errors functions.

`echo $wpdb->last_error;`

or

`echo $wpdb->show_errors;`



2. If no error is visible then you must print your last query using with last query function.

`echo $wpdb->last_query;`

3. Copy and paste your last query in your Phpmyadmin > Your Database -> Table -> SQL tab, click on the Go button, and you will definitely get proper solutions(errors) in it.
