CodeIgniter:使用HTML5必需属性的输入框

Question

我在CodeIgniter框架中有一个表单,我想使用HTML"required"属性.我怎样才能做到这一点？

$data = array(
              'name'        => 'username',
              'id'          => 'username',
              'value'       => 'johndoe',
              'maxlength'   => '100',
              'size'        => '50',
              'style'       => 'width:50%',
            );

echo form_input($data); 

结果需要:

    <input type="text" name="username" id="username" value="johndoe" 
required maxlength="100" size="50" style="width:50%" /> 

Answer 1

您只需将其添加到阵列即可.

$data = array(
              'name'        => 'username',
              'id'          => 'username',
              'value'       => 'johndoe',
              'maxlength'   => '100',
              'size'        => '50',
              'style'       => 'width:50%',
              'required' => 'required'
 );

echo form_input($data);
