Cannot Edit the data saved in the database - php

Question

I'm using cake php for project, but i cannot edit the data i saved in the database. The edit function i used in the controller looks like below.
public function edit($id = null) {
if (!$this->Seller->exists($id)) {
throw new NotFoundException(__('Invalid seller'));
}
if ($this->request->is(array('post', 'put'))) {
if ($this->Seller->save($this->request->data)) {
$this->Session->setFlash(__('The seller has been saved.'));
return $this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('The seller could not be saved. Please, try again.'));
}
} else {
$options = array('conditions' => array('Seller.' . $this->Seller->primaryKey => $id));
$this->request->data = $this->Seller->find('first', $options);
}
}
My edit.ctp file looks like below.
<div class="sellers form">
<?php echo $this->Form->create('Seller'); ?>
<fieldset>
<legend><?php echo __('Edit Seller'); ?></legend>
<?php
echo $this->Form->input('id');
echo $this->Form->input('first_name');
echo $this->Form->input('last_name');
echo $this->Form->input('email');
echo $this->Form->input('phone_no');
echo $this->Form->input('address');
echo $this->Form->input('latitide');
echo $this->Form->input('longitude');
echo $this->Form->input('username');
echo $this->Form->input('password');
echo $this->Form->input('product_type');
echo $this->Form->input('product_description');
echo $this->Form->input('approval');
?>
</fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
</div>
<div class="actions">
<h3><?php echo __('Actions'); ?></h3>
<ul>
<li><?php echo $this->Form->postLink(__('Delete'), array('action' => 'delete', $this->Form->value('Seller.id')), array(), __('Are you sure you want to delete # %s?', $this->Form->value('Seller.id'))); ?></li>
<li><?php echo $this->Html->link(__('List Sellers'), array('action' => 'index')); ?></li>
</ul>
</div>
I can save and delete data in the database, but when i edit the saved data, saved changes are not getting saved. Please help me with this. Thanks in advance.

Answer 1

You need this :
$this->Seller->primaryKey= $id;
just before the first if .
edited - code working
public function edit($id = null) {
$this->Category->id = $id;
if (!$this->Category->exists()) {
throw new NotFoundException(__('Invalid category'));
}
if ($this->request->is('post') || $this->request->is('put')) {
if ($this->Category->save($this->request->data)) {
$this->Session->setFlash(__('Catégorie modifiée avec succès'),array('action' => 'index'));
} else {
$this->flash(__('Categorie pas modifiée...Réessayer Plus tard'),array('action' => 'index'));
}
} else {
$this->request->data = $this->Category->read(null, $id);
}
}

The reason you are able to add/delete, and not edit is because the primary key is not being submitted with the form. $id will only be there on initial page load, not when the form is submitted, since it then relies on the id being in $this->request->data. A good way to check if this is the case is to look in the database table you are saving to. If there is a new inserted record with the data you are trying to save, then this is it.
public function edit($id = null) {
$this->Seller->id = $id
if (!$this->Seller->exists($id)) {
throw new NotFoundException(__('Invalid seller'));
}
if ($this->request->is(array('post', 'put'))) {
if ($this->Seller->save($this->request->data)) {
$this->Session->setFlash(__('The seller has been saved.'));
return $this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('The seller could not be saved. Please, try again.'));
}
} else {
$this->request->data = $this->Seller->read(null, $id);
}
}
#may was correct, only he was referring to a different Model name than what you were using: it should be Seller not Category.
I would also change your find() call to use read() instead:
$this->request->data = $this->Seller->read(null, $id);
