Easiest method: Code: // Prepend an item to the array Another method: Code: // Create the country-array

Just to correct yours a little bit. form_drop_down() array doesn't start at 1. It's because you pre-format the array within the model, which make them always has key bigger than 0 Code: // This one Actually, it's faster to do like what PhilTem said, since it's 1 less loop.

[quote author="hunter" date="1332332412"]Thanx ........... But i got a simplest one ....... Code: <? $country[0] = 'Select Country'; ksort($country);?> You should be careful with ksort since it may screw up your sorting. That's why I tend to do stuff just like I posted above. Even though it's not made in the view but actually put inside MY_Model which creates an array that has the format needed for form_dropdown. You can soon check my MY_Model code at GitHub if you wanna know more about how I implemented it.

Just set it up before you create the rest of the entries in your loop. 1 extra line. I always use an id of 0 since autoincremented db fields start at 1 so it will never interfere with the real data, and then use 'is_natural_no_zero' for form validation if it is a required field. Code: function selcountry()

Where you have $country should be the numeric index of the $country value you want as the default, which is probably 0. The value is available in $this->input->post('name') with the rest of your form elements in your controller. I hope you are using form validation. You would do it after it passes validation.

Well, if you haven't submitted the form yet but are checking the post value, it will return boolean FALSE. If the form is submitted, then 0 must be the value of the option you had selected in the dropdown. 0 is your default. |
