Hello,
I read your tutorial but there is difficulty trying to Removing Required causes of validation could you please improve it?
For example in customer adding I need customer name and mobile number only
"
To remove validation, you will need to edit few files
1. app/controllers/admin/sleectTheControllerYouWantEdeit
2. themes/default/admin/selectTheAppropriateFolderOrFile
3. Database table to accept null value for that field
Please alter the database table to accept the null for your inputs (postal code).
1. Open phpmyadmin and select the database
2. Select the customers table
3. Click Structure
4. Click change on field name (city) line
5. Tick/check the null checkbox
6. Click Save
Now try to add customer without city. You won't get any error as we have remove the
required validation for this input.
You can use these steps to remove the required field for any other fields.
Please be careful while removing the required from some fields as these might be used
in other modules, like removing the required validation for email to accept customer
with no email could cause issues/errors for emailing the invoice to customer in sale/pos.
Let say we want to remove the restriction from postal code from add customer
Open themes/default/views/customers/add.php and look for city input code
<?php echo form_input('city', '', 'class="form-control" id="city" required="required"'); ?>
We need to remove the required (you might need to check pattern) attributes. We will delete the code below
required="required"
You need to check the validation rules in app/config/form_validation.php We are validation
if ($this->form_validation->run('companies/add') == true) {
so search 'companies/add' array and then look for array with field 'city' and remove the required from rules
and now your rules will be as
'rules' => 'other_validation'
For some pages, you need to check the rules in controller as app/controllers/customers.php and look for
function add() and see the validation line on top as
$this->form_validation->set_rules('city', lang("city"), 'required|other_validation');
Remove the line, if you want to keep other validation, please remove required from last part of the
validation. After this our validation line will look as
$this->form_validation->set_rules('city', lang("city"), 'other_validation');
