Hey guys,

I'm trying to save some form fields to my DB that I am creating dynamically with a button using jquery.

When I try to save the values to my database, it gives me this message:

preg_replace(): Parameter mismatch, pattern is a string while replacement is an array

Which is because im trying to save an array apparently. But how do I then save the correct single values to my database?

// Workout controller
$workout->exercise_id = Input::get('exercise_id');

// Create view
    <div class="form-group">
        {{ Form::label('exercise_id', 'Øvelse') }}
        {{ Form::text('exercise_id[][exercise_id]', null, ['class'=>'form-control']) }}
        {{ $errors->first('exercise_id') }}
    </div>

    <button class="add-exercise">Add exercise to workout</button>

// Jquery, if it even matters 
   var max_fields      = 10; //maximum input boxes allowed
    var wrapper         = $(".form-container"); //Fields wrapper
    var add_button      = $(".add-exercise"); //Add button ID

    var x = 1; //initial text box count
    $(add_button).click(function(e){ //on add input button click
        e.preventDefault();
        if(x < max_fields){ //max input box allowed
            x++; //text box increment
            $(wrapper).append('<div class="form-group">' +
            '<label name="exercise_id[]">Øvelse</label>' +
            '<input type="text" name="exercise_id[]"/>' +
                '<a href="#" class="remove_field">Remove</a>' +
            '</div>'); //add input box
        }
    });

    $(wrapper).on("click",".remove_field", function(e){ //user click on remove text
        e.preventDefault(); $(this).parent('div').remove(); x--;
    })

Any help is appreciated :)
