Question

i have made a code to generate 11 digit random number and i want to save all number in database

admin_create_epin.ctp(view)

<tr>
   Add E-pin:(No of E-Pin)
   <td><?php echo $this->Form->input('e_pin',array('label'=>false));?></td> 
</tr>

epins_controlller.php

 public function admin_create_epin(){

   $limit = $this->data['Epin']['e_pin'];

   for($i=0;$i<$limit;$i++)
      {
         $random = substr(number_format(time() * rand(),0,'',''),0,11)."<br/>";
         $this->data['Epin']['e_pin'] = $random;

        //pr($this->data); it's show all random number

         $this->Epin->save($this->data);          // i have problem only here it's save only last random number
         $this->Session->setFlash("Epin has been added");
         $this->Redirect(array('action'=>'admin_create_epin')); 
    }   
}

Issue:Code generate all random number but i have problem in my code insert only last random number not all and i want to insert all random number

thanks

Answer 1

1) You have to move Redirect() outsite the loop.

2) After the first $this->Epin->save(...) last inserted id is stored in $this->Epin->id and then is used for update records with this id for following iterations. So you will have only one record inserted, and rewritten in the last iteration.

Reset it before saving:

for($i=0;$i<$limit;$i++)
  {
     //...
     $this->Epin->id = null; // <- force insert in the next save
     $this->Epin->save($this->data);          // i have problem only here it's save only last random number
     //...
} 

Also you can try create() method:

$this->Epin->save($this->Epin->create($this->data));
