Meine eigenen Validierungsmethoden (CodeIgniter) gibt immer einen Fehler zurück, auch wenn ich denke, dass es nicht

Question

Könnte jemand bitte einen Blick auf meinen Code und sagen Sie mir, was ich falsch mache!

hier ist meine Ansicht Datei (HTML-Formular)

Ich habe versucht, so viele Variationen von Daten, aber es gibt immer den Fehler Ich bin schon frustriert Ich sehe nicht das Problem mit diesem Feld (dob), bitte helfen!

Answer 1

Den Code nehmen, den Sie zur Verfügung gestellt haben und damit spielen. Ich habe folgendes bekommen:

Ich habe ein paar kleine Änderungen vorgenommen. Finde die Unterschiede!

The View - test_form.php

<?php $attrib = array('class' => 'form-horizontal col-lg-6') ?> 

<?php 
if (isset($_POST['save'])) { 
    echo validation_errors('<div class="alert alert-danger">', '</div>'); 
} 
?> 
<?= form_open('welcome/form', $attrib); ?> 
    <div class="form-group"> 
     <div class="input-group"> 
      <div class="input-group-addon" id="label">Date of birth</div> 
      <input type="text" name="dob" class="form-control" value="<?= isset($dob)?$dob:'' ?>"> 
     </div> 
    </div> 

    <div class="form-group"> 
     <div class=""> 
      <button type="submit" name="save" class="btn btn-primary">Save</button> 
     </div> 
    </div> 
<?= form_close(); ?> 

The Controller - welcome.php

<?php 
defined('BASEPATH') OR exit('No direct script access allowed'); 

/** 
* Class Welcome 
* 
* 
* @property CI_Form_validation form_validation 
* @property CI_Input   input 
*/ 
class Welcome extends CI_Controller { 

    public function __construct() { 
     parent::__construct(); 
     $this->load->helper('form'); 
     $this->load->library('form_validation'); 
    } 

    public function test() { 
     $date = '2017/12/01'; 
     echo $date; 
     echo '<br>'; 
     var_dump($this->date_valid($date)); // returns false 

     $date = '01/03/1970'; 
     echo $date; 
     echo '<br>'; 
     var_dump($this->date_valid($date)); // returns true 

     $date = '01-03-1970'; 
     echo $date; 
     echo '<br>'; 
     var_dump($this->date_valid($date)); // returns true 

    } 

    public function form() { 
     $config = array(
      array(
       'field' => 'dob', 
       'label' => 'Date of birth', 
       'rules' => 'exact_length[10]|callback_date_valid', 
       'errors' => array(
        'exact_length' => 'Sorry! invalid length for a date', 
        'date_valid' => 'Sorry! invalid date format', 
       ) 
      ) 
     ); 

     $this->form_validation->set_rules($config); 
     if ($this->input->post('save') !== NULL) { 
      if ($this->form_validation->run() == TRUE) { 
       echo "Updating the Database"; 
      } 
     } 

     $this->load->view('test_form'); 
    } 

    public function date_valid($date) { 
     if (strpos($date, '/') != FALSE) { 
      list($day, $month, $year) = explode("/", $date); 
      if ($this->tarehe($day, $month, $year)) { 
       return TRUE; 
      } else { 
       return FALSE; 
      } 

     } elseif (strpos($date, '-') != FALSE) { 
      list($day, $month, $year) = explode("-", $date); 
      if ($this->tarehe($day, $month, $year)) { 
       return TRUE; 
      } else { 
       return FALSE; 
      } 
     } elseif (strpos($date, '.') != FALSE) { 

      list($day, $month, $year) = explode(".", $date); 

      if ($this->tarehe($day, $month, $year)) { 
       return TRUE; 
      } else { 
       return FALSE; 
      } 
     } else { 
      return FALSE; 
     } 
    } 

    public function tarehe($day, $month, $year) { 

     $first = $day[0]; 
     $second = $day[1]; 

     if ($first < 0) { 
      $day = $second; 
     } 

     if ($day > 0 && $day <= 31) { 
      $first = $month[0]; 
      $second = $month[1]; 

      if ($first < 0) { 
       $month = $second; 
      } 

      if ($month > 0 && $month <= 12) { 
       $limit_down = date('Y') - 17; 
       $limit_up = date('Y') - 50; 
       if ($year < $limit_down && $year > $limit_up) { 

        return TRUE; 
       } else { 

        return FALSE; 
       } 
      } else { 

       return FALSE; 
      } 
     } else { 

      return FALSE; 
     } 
    } 
} 

So habe ich Ihren Code zu meinem welcome.php Controller hinzugefügt.

1. ein Prüfverfahren Erstellt Ihre Datumsformate /welcome/test testen Sie Ihren Rückrufcode und die tarehe Methode zu testen ... die Formate und Werte zu testen ...

2. Ich habe Die Formularmethode, um Ihr Formular für dob mit dem Rückruf zu testen.
   willkommen/form

Sie ernsthaft auf den Code in Ihrem $ this-> form_validation_> run() Abschnitt des Controllers suchen müssen ... Warum die gleiche Code für die Wahr und Falsch Bedingungen und was macht dieser Code?

Ist das Ihr echtes Problem?
