Codeigniter - 使用set_value（）填充表单进行编辑（不涉及POST） [英] Codeigniter - using set_value() to populate a form for editing (with no POST involved)

问题描述

我有一个包含表单的视图。与输入字段和单选按钮。此表单需要填充数据库中的数据，以便将其用作数据编辑表单。

I have a view containing a form. with input fields and radio buttons. This form needs to be populated with the data from database, so as to use it as an data editing form.

我已使用set_value（）函数进行表单验证其中视图从post后的相同控制器调用。 但是如何使用set_value函数与POST？即只需填充加载的视图中的窗体中的值。

I have used the set_value() function for the form validation where the view is called from the same controller after the post. But how to use set_value function with out a POST? i.e. simply populate the values in a form in the view that's loaded. with say, an Array or object from database.

推荐答案

您可以像这样使用

set_value('myfield', isset($databaseData['myfield']) ? $databaseData['myfield'] : '');

$ databaseData 您已在控制器中加载并传递给视图的数据库

$databaseData will contain the data from the database which you have loaded in the controller and passed to view

$data['databaseData']= $this->my_model->find($parameters);

$this->load->view('myformview',$data);
