My form field looks like this
echo form_label('Quantity', 'quantity');
echo form_input('quantity', $quantityx);
I modified it to retain form values
echo form_label('Quantity', 'quantity');
echo form_input('quantity', $this->input->post('quantity'));
I set the $quantityx above in the code behind in order to populate a value from the database so a user can edit a row.
How can I retain the value for validations, and have a variable to populate from the database at the same time?
I have tried this a well
echo form_label('Quantity', 'quantity');
echo form_input('quantity', set_value($quantityx));
Thanks for any suggestions
You can set them like this, if set_value('columnanme')
returns false
then a form $_POST
did not take place so what it will do is get the data from the data base example
$profile->firstname
$firstname = set_value('firstname') == false ? $profile->firstname : set_value('firstname');
$lastname = set_value('lastname') == false ? $profile->lastname : set_value('lastname');
Use it like:
echo form_label('Firstname', 'fname');
echo form_input('firstname', $firstname);
echo form_label('Firstname', 'lnamey');
echo form_input('firstname', $lastname);
in your case you can do:
$quantity = set_value('Quantity') == false ? $quantityx : set_value('Quantity');
ANd on your form:
echo form_label('Quantity', 'quantity');
echo form_input('quantity', $quantity);
Assuming that $quantityx
holds the data from your databse
EDIT
=============================================
Just use set_values()
second parameter as the default value. i.e set_value('name_of_input_field',$data_from_databse_as_default);
If this does not work, then use my first answer.
