只有“Type = Text” & “Textarea”重定向错误后重新填充;但是“选择” & “复选框”不在CodeIgniter 3 [英] Only "Type=Text" & "Textarea" Re-Populates After Redirect Error; But "Select" & "Checkboxes" Doesn't in CodeIgniter 3

问题描述

您好我是新的CI，并试图在这种形式，如果验证输出错误，那么用户不应该松动字段值。但它只是重新填充文本&

 < span class =error><？php echo $ validation_errors; ？>< / span> 
<？php echo form_open_multipart（'user / post_property'）; > 
< input name =v_item_titleplaceholder =Property Title Goes Here ..value =<？php echo $ v_item_title;？& /> 
< textarea name =v_item_descriptionplaceholder =Description><？php echo $ v_item_description; ？>< / textarea> 
< select name =v_item_categoryvalue =<？？php echo $ v_item_category;？>> 
< option value =>选择< / option> 
< option value =Apartment<？php echo $ v_item_category; ？>>公寓< / option> 
< option value =Barn<？php echo $ v_item_category; ？>> Barn< / option> 
< / option> 
< / select> 
< input type =hiddenname =v_item_payment_visavalue =0/> 
< input type =checkboxname =v_item_payment_visavalue =1<？php echo $ v_item_payment_visa; > />< span class =li-font> VISA< / span> 
< input type =submitvalue =Submit> 
<？php echo form_close（）; > 
  

控制器 -

 code> $ this-> form_validation-> set_rules（'v_item_title'，'Property title'，'trim | required | xss_clean | max_length [100]'）; 
 if（$ this-> form_validation-> run（）== FALSE）{
 $ this-> session-> set_userdata（'validation_errors'，validation_errors（））; 
 $ this-> session-> mark_as_flash（'validation_errors'）; // data will automatically delete their after redirect 
 $ this-> session-> set_flashdata（'v_item_title'，$ this-> input-> post（'v_item_title'））; 
 $ this-> session-> flashdata（'v_item_title'）; 
 $ this-> session-> set_flashdata（'v_item_description'，$ this-> input-> post（'v_item_description'）） 
 $ this-> session-> flashdata（'v_item_description'）; 
 $ this-> session-> set_flashdata（'v_item_category'，$ this-> input-> post（'v_item_category'））; 
 $ this-> session-> flashdata（'v_item_category'）; 
 $ this-> session-> set_flashdata（'v_item_payment_visa'，$ this-> input-> post（'v_item_payment_visa'））; 
 $ this-> session-> flashdata（'v_item_payment_visa'）; 
 redirect（'user / dashboard＃new'）; 
} else {
  

重新导向至 -

  public function dashboard（）{
 if（$ this-> session-> userdata（'is_logged_in'））{
 $ data [ validation_errors'] = $ this-> session-> userdata（'validation_errors'）; 
 $ data ['v_item_title'] = $ this-> session-> userdata（'v_item_title'）; 
 $ data ['v_item_description'] = $ this-> session-> userdata（'v_item_description'）; 
 $ data ['v_item_category'] = $ this-> session-> userdata（'v_item_category'）; 
 $ data ['v_item_payment_visa'] = $ this-> session-> userdata（'v_item_payment_visa'）; 
 $ data ['homepage'] ='../../templates/vacations/users/dashboard'; 
 $ this-> load-> view（'template_users'，$ data）; 
} else {
  

花了一些时间，寻求帮助。

解决方案

最后我得到了工作 -

 < span class =error><？php echo $ validation_errors; ？>< / span> 
<？php echo form_open_multipart（'user / post_property'）; > 
< input name =v_item_titleplaceholder =Property Title Goes Here ..value =<？php echo $ v_item_title;？& /> 
< textarea name =v_item_descriptionplaceholder =Description><？php echo $ v_item_description; ？>< / textarea> 
< select name =v_item_category> 
< option value =0>选择< / option> 
< option value =Apartment<？php if（$ this-> session-> flashdata（'v_item_category'）==='Apartment'）echo（'selected'）？> ;公寓< / option> 
< option value =Barn<？php if（$ this-> session-> flashdata（'v_item_category'）==='Barn'）echo（'selected'）？> ; Barn< / option> 
< / option> 
< / select> 
< input type =hiddenname =v_item_payment_visavalue =0/> 
< input type =checkboxname =v_item_payment_visavalue =1<？php if（$ this-> session-> flashdata（'v_item_payment_visa'））echo'checked = '; > />< span class =li-font> VISA< / span> 
< input type =submitvalue =Submit> 
<？php echo form_close（）; > 
  

Hi I am new with CI and trying to work on this form where if validation outputs error then user shouldn't loose the field values. But it only re-populates text & textarea, not checkboxes and select.

Form-

<span class="error"><?php echo $validation_errors; ?></span>
<?php echo form_open_multipart('user/post_property'); ?>
<input name="v_item_title" placeholder="Property Title Goes Here.." value="<?php echo $v_item_title; ?>" />
<textarea name="v_item_description" placeholder="Description" ><?php echo $v_item_description; ?></textarea>
<select name="v_item_category" value="<?php echo $v_item_category; ?>">
<option value="">Select</option>
<option value="Apartment" <?php echo $v_item_category; ?>>Apartment</option>
<option value="Barn" <?php echo $v_item_category; ?>>Barn</option>
</option>
</select>
<input type="hidden" name="v_item_payment_visa" value="0"  />
<input type="checkbox" name="v_item_payment_visa" value="1" <?php echo $v_item_payment_visa; ?> /><span class="li-font">VISA</span>
<input type="submit" value="Submit">
<?php echo form_close(); ?>

Controller-

$this->form_validation->set_rules('v_item_title', 'Property title', 'trim|required|xss_clean|max_length[100]');
if($this->form_validation->run() == FALSE) {
$this->session->set_userdata('validation_errors', validation_errors());
$this->session->mark_as_flash('validation_errors'); // data will automatically delete themselves after redirect
$this->session->set_flashdata('v_item_title', $this->input->post('v_item_title'));
$this->session->flashdata('v_item_title');
$this->session->set_flashdata('v_item_description', $this->input->post('v_item_description'));
$this->session->flashdata('v_item_description');
$this->session->set_flashdata('v_item_category', $this->input->post('v_item_category'));
$this->session->flashdata('v_item_category');
$this->session->set_flashdata('v_item_payment_visa', $this->input->post('v_item_payment_visa'));
$this->session->flashdata('v_item_payment_visa');
redirect('user/dashboard#new');
} else {

Redirects to-

public function dashboard() {
if($this->session->userdata('is_logged_in')){
$data['validation_errors'] = $this->session->userdata('validation_errors');
$data['v_item_title'] = $this->session->userdata('v_item_title');
$data['v_item_description'] = $this->session->userdata('v_item_description');
$data['v_item_category'] = $this->session->userdata('v_item_category');
$data['v_item_payment_visa'] = $this->session->userdata('v_item_payment_visa');
$data['homepage'] = '../../templates/vacations/users/dashboard';
$this->load->view('template_users',$data);
}else{

Had spent some good time on it but getting nowhere. Seeking help here.

解决方案

Finally I got it working-

<span class="error"><?php echo $validation_errors; ?></span>
<?php echo form_open_multipart('user/post_property'); ?>
<input name="v_item_title" placeholder="Property Title Goes Here.." value="<?php echo $v_item_title; ?>" />
<textarea name="v_item_description" placeholder="Description" ><?php echo $v_item_description; ?></textarea>
<select name="v_item_category">
<option value="0">Select</option>
<option value="Apartment" <?php if($this->session->flashdata('v_item_category') === 'Apartment') echo('selected')?>>Apartment</option>
<option value="Barn" <?php if($this->session->flashdata('v_item_category') === 'Barn') echo('selected')?>>Barn</option>
</option>
</select>
<input type="hidden" name="v_item_payment_visa" value="0"  />
<input type="checkbox" name="v_item_payment_visa" value="1" <?php if($this->session->flashdata('v_item_payment_visa')) echo 'checked="checked"'; ?> /><span class="li-font">VISA</span>
<input type="submit" value="Submit">
<?php echo form_close(); ?>
