CodeIgniter ein auf einem dynamischen Formular

Question

Ich versuche, ein Formular zu erstellen, die eine Eingabe zB nimmt. 3 und erzeugt dann 3 bildet in einer Schleife auf, wie die Eingabe. Könnte jemand durchsehen und sehen, ob mein Code korrekt ist? Im Moment nicht meine Form Validierung sofort aus irgendeinem Grunde, und ich bin nicht sicher, wie ich vorgehen kann.

Es gibt eine adulte Form und ein Kind Form. Beide hängen von den Eingaben von einer anderen Seite ab.

Das ist meine Ansicht

<?php echo form_open_multipart('Public/Details/next','class="inputform"');?> 
        <h3>Adults</h3> 
        <?php for($i=0;$i<$adults;$i++){?>

Ich hoffe, dass mir jemand helfen kann mit diesem. Ich habe für eine lange Zeit hindurch sah, und ich kann nicht sehen, was ich bin fehlt oder vielleicht die ganze Sache ist falsch.

ich für Sie erstellt eine einfache Steuerung und Ansicht.

Controller:

public function test() 
    { 
     $view_data = array(); 
     $view_data['step'] = 1; // default step 
     //step 1 
     if($this->input->post('_step') AND $this->input->post('_step')==1) { 
      $view_data['step'] = 1; 
      $this->form_validation->set_rules('children_length', 'How many children', 'trim|required|integer|min_length[1]'); 
      $this->form_validation->set_rules('adult_length', 'How many adult', 'trim|required|integer|min_length[1]'); 

      if($this->form_validation->run()) { 
       //set variable for status 2 
       $view_data['step'] = 2; 
      } 
     } 

     //step 2 
     if($this->input->post('_step') AND $this->input->post('_step')==2) { 
      $view_data['step'] = 2; 

      $children_length = (int)$this->input->post('children_length'); 
      $adult_length = (int)$this->input->post('adult_length'); 

      //validation for childrens 
      for($i=0;$i<$children_length;$i++) { 
       $this->form_validation->set_rules('childrens['.$i.'][firstname]', 'Children '.$i.' - firstname', 'trim|required'); 
       $this->form_validation->set_rules('childrens['.$i.'][lastname]', 'Children '.$i.' - lastname', 'trim|required'); 
      } 
      //validation for adults 
      for($i=0;$i<$children_length;$i++) { 
       $this->form_validation->set_rules('childrens['.$i.'][firstname]', 'Children '.$i.' - firstname', 'trim|required'); 
       $this->form_validation->set_rules('childrens['.$i.'][lastname]', 'Children '.$i.' - lastname', 'trim|required'); 
      } 

      if($this->form_validation->run()) { 
       //set variable for status 3 
       //here save etc 
       $view_data['step'] = 3; 
      } 
     } 


     $this->load->view('/test', $view_data); 
    } 

Ausblick:

<?php 

if($step==3) { 
    //step 3 - show array from step 2 
    echo '<h3>Step 3</h3>'; 
    echo '<pre>'; 
     print_r($this->input->post()); 
    echo '</pre>'; 
}elseif($step==2) { 
    //step 2 Generation form fo childrens and adults 
    echo '<h3>Step 2</h3>'; 
    echo form_open('', '', ['_step'=>2,'children_length'=>$this->input->post('children_length'),'adult_length'=>$this->input->post('adult_length')]); 
     echo '<div style="color:red">'.validation_errors().'</div>'; 

     echo '<h4>Childrens</h4>'; 
     for($i=0;$i<$this->input->post('children_length');$i++) {

      echo form_input(['type'=>'text','name'=>'childrens['.$i.'][lastname]','value'=>set_value('childrens['.$i.'][lastname]'),'placeholder'=>'Children '.$i.' - lastname']); 
      echo '<br><br>'; 
     } 

     echo '<h4>Adults</h4>'; 
     for($i=0;$i<$this->input->post('adult_length');$i++) { 
      echo form_input(['type'=>'text','name'=>'adults['.$i.'][firstname]','value'=>set_value('adults['.$i.'][firstname]'),'placeholder'=>'Adult '.$i.' - firstname']); 
      echo form_input(['type'=>'text','name'=>'adults['.$i.'][lastname]','value'=>set_value('adults['.$i.'][lastname]'),'placeholder'=>'Adult '.$i.' - lastname']); 
      echo '<br><br>'; 
     } 
     echo form_input(['type'=>'submit','value'=>'Next (go to step 3)']); 
    echo form_close(); 
}else { 
    //step 1 How many children as adults 
    echo '<h3>Step 1</h3>'; 
    echo form_open('', '', ['_step'=>1]); 
     echo '<div style="color:red">'.validation_errors().'</div>'; 
     echo form_input(['type'=>'text','name'=>'children_length','value'=>set_value('children_length'),'placeholder'=>'How many children']); 
     echo form_input(['type'=>'text','name'=>'adult_length','value'=>set_value('adult_length'),'placeholder'=>'How many adult']); 
     echo form_input(['type'=>'submit','value'=>'Next (go to step 2)']); 
    echo form_close(); 
}
