php codeigniter - 表单助手 - 如何在无线电输入上实现 set_value

Question

我正在使用 codeigniters 表单助手为我的网站设置反馈表单。

我的表单已创建并已实施验证，一切正常。

我唯一的问题是添加 set_value() 函数以在发生错误时重新填充表单。

我无法让它在我的无线电输入上工作，如何将 set_value() 函数添加到无线电类型。

代码：

      <ul> 
          <li><?php echo form_radio('found_by', 'newspaper_advert', set_value('found_by')); ?> Newspaper advert</li>
          <li><?php echo form_radio('found_by', 'press_release', set_value('found_by')); ?> Press release</li>
          <li><?php echo form_radio('found_by', 'text_message', set_value('found_by')); ?> Text message</li>
          <li><?php echo form_radio('found_by', 'email', set_value('found_by')); ?> Email</li>
          <li><?php echo form_radio('found_by', 'refferal', set_value('found_by')); ?> Referred to by a friend</li>
          <li><?php echo form_radio('found_by', 'telemarketing', set_value('found_by')); ?> Telemarketing</li>
          <li><?php echo form_radio('found_by', 'leaflet_flyer', set_value('found_by')); ?> Leaflet or flyer</li>
          <li><?php echo form_radio('found_by', 'radio', set_value('found_by')); ?> Radio</li>
          <li><?php echo form_radio('found_by', 'television', set_value('found_by')); ?> Television</li>
          <li><?php echo form_radio('found_by', 'internet_advert', set_value('found_by')); ?> Internet advert</li>
          <li><?php echo form_radio('found_by', 'search_engine', set_value('found_by')); ?> Search engine</li>
          <li><?php echo form_radio('found_by', 'none', set_value('found_by')); ?> None of the above</li>
      </ul>

Answer 1

set_value 仅适用于输入和文本区域。你需要set_radio

set_radio()

允许您以提交时的状态显示单选按钮。
该函数与上面的 set_checkbox() 函数相同。

<input type="radio" name="myradio" value="1" <?php echo set_radio('myradio', '1', TRUE); ?> />
<input type="radio" name="myradio" value="2" <?php echo set_radio('myradio', '2'); ?> />

Answer 2

<?= form_radio('found_by', 'newspaper_advert', $found_by == 'newspaper_advert'); ?>

Answer 3

试试这个，它对我有用：

性别：

< ?php echo form_radio("gender", "Female", NULL, set_radio('gender', 'Female')); ?>Female

< ?php echo form_radio("gender", "Male", NULL, set_radio('gender', 'Male')); ?>Male

Answer 4

<input type="radio" name="myradio" value="1" <?php echo  set_radio('myradio', '1'); ?> />
<input type="radio" name="myradio" value="2" <?php echo  set_radio('myradio', '2'); ?> />
<input type="radio" name="myradio" value="3" <?php echo  set_radio('myradio', '3'); ?> />
<input type="radio" name="myradio" value="4" <?php echo  set_radio('myradio', '4'); ?> />

太容易了......

Answer 5

 <?php echo form_radio( array( 'name'=> 'age_group','id'=>'age_group','class'=> 'input-xsmall focused inputError','type'=>'radio',set_radio('age_group', 'under 18', TRUE) ) ). "under 18"; ?><br />
            <?php echo form_radio( array( 'name'=> 'age_group','id'=>'age_group','class'=> 'input-xsmall focused inputError','type'=>'radio',set_radio('age_group', '18 to 29', TRUE) ) ). "18 to 29"; ?><br />
            <?php echo form_radio( array( 'name'=> 'age_group','id'=>'age_group','class'=> 'input-xsmall focused inputError','type'=>'radio',set_radio('age_group', '30 to 49', TRUE) ) ). "30 to 49"; ?><br />
            <?php echo form_radio( array( 'name'=> 'age_group','id'=>'age_group','class'=> 'input-xsmall focused inputError','type'=>'radio',set_radio('age_group', 'above 49', TRUE) ) ). "above 49"; ?>

这是正确的代码吗？
