Solution 1

There is not much information, but did you check for type errors?

Like shouldn't it be $_POST['op'] in the second part?
And same for Venue_name and Venue_date.

Solution 3

The third line is unnecessary. Replace it with these:

PHP

if(isset($_POST['op']))
{
    // Insert your codes here
    // Additionally $_POST[op] is an invalid usage, it must be $_POST['op']
}
else
{
    // If there is no post variable whose name is 'op'
}
