How to avoid “The action you have requested is not allowed” error with Knockout postJson function call

How to create forms with conditional options

由 China☆狼群 提交于 2019-12-11 10:50:24
问题 I want to create a form with two dropdown boxes so that the options in the second dropdown depend on the choices in the first dropdown. So Dropdown1 might ask the user to opt for CourseA or CourseB and Dropdown2 might present sets of dates - but the dates would differ depending on what the choice in Dropdown1 had been. I have tried using the post array to set the Dropdown2 choices but then realized that it is not set until the form is submitted. My problem happens before the form is submitted

Codeigniter - edit form (repopulating) with edit_unique

由 a 夏天 提交于 2019-12-02 03:41:29
问题 It seems that the edit_unique function, which is desribed here - Validating Uniqueness In CodeIgniter When Updating A Record, kills the set_value function. All works fine, which something like this... echo form_input('username', set_value('username',$user->username)); But when using the edit_unique validation, the value is empty after submitting the form. Post-Variables are ok and also the validation has no errors - but the value is not set. Any idea how I can fix that? 回答1: Ok - found it
