Navigation:  Development > Function Reference > InformationSet > Save

Save method used to Add or Update data in database table. We can use two method to save data.
 
Save by Variable:

Format App::InformationSet(NAME)->Save($data);
 
This data variable  formed like $data['Information'] = array(Field1=Value1,Field2=Value2,Field3=Value3)

 
Note: For all InformationSet model name is always Information.
 

For example 
// Array Format 1
$data['Information'] = Array
(
    'adminref' => 1,
    'entrydate' => '2012-12-12 22:23:41',
    'lastmodified' => '2012-12-14 00:13:02',
    'title' => 'How to install Application',
    'category' => 2,
    'description' => 'Application is one of the easiest solutions to incorporate new features.',
    'status' => 'Public'
);

 
// Array Format 2
$data['Information']['adminref'] = 1;
$data['Information']['entrydate'] = '2012-12-12 22:23:41';
$data['Information']['lastmodified'] = '2012-12-14 00:13:02';
$data['Information']['title'] = 'How to install Application';
$data['Information']['category'] = 2;
$data['Information']['description'] = 'Application is one of the easiest solutions to incorporate new features.';
$data['Information']['status'] = 'Public';

 
$obj = App::InformationSet('blogpost')->Save($data);

 

Save by Magic Method:

This is another convenient process. In the method first we set all field value in Model object then call Save function.
 
Format :

App::InformationSet(NAME)

    ->set[fieldName1](Value1)
    ->set[fieldName2](Value1)
    ->Save();
 
Example 1: 
$obj = App::InformationSet('blogpost')
    ->setAdminref(1)
    ->setEntrydate('2012-12-12 22:23:41')
    ->setLastmodified('2012-12-14 00:13:02')
    ->setTitle('How to install Application')
    ->setCategory(2)
    ->setDescription('Application is one of the easiest solutions to incorporate new features.')
    ->setStatus('Public')
    ->Save();
 
 
Add/Update Row:
By default Save function insert a new row in table but it update existing row if we set id in save function. 
 
Note: After inserting a row the new id stored in Model Object and update previous data on next attempt so, for repeated insert in same session we set NULL in id field. 
 

// Create New entry update on next attempted
$obj = App::InformationSet('blogpost')
    ->setAdminref(1)
    ->setEntrydate('2012-12-12 22:23:41')
    ->setLastmodified('2012-12-14 00:13:02')
    ->setTitle('My New Entry')
    ->setCategory(2)
    ->setDescription('Hello World')
    ->setStatus('Public')
    ->Save();
 
// Update entry

$obj = App::InformationSet('blogpost')
    ->setId(5)
    ->setAdminref(1)
    ->setEntrydate('2012-12-12 22:23:41')
    ->setLastmodified('2012-12-14 00:13:02')
    ->setTitle('My New Entry')
    ->setCategory(2)
    ->setDescription('Hello World')
    ->setStatus('Public')
    ->Save();
 

// Always Create New entry
$obj = App::InformationSet('blogpost')
    ->setId(null)
    ->setAdminref(1)
    ->setEntrydate('2012-12-12 22:23:41')
    ->setLastmodified('2012-12-14 00:13:02')
    ->setTitle('My New Entry')
    ->setCategory(2)
    ->setDescription('Hello World')
    ->setStatus('Public')
    ->Save();

 

Return Value

After saving model store Id(AUTO INSERT) and Error Report in returned object.
 
$error = $obj->getErrorInfo(); // Return Error
$id= $obj->getId(); // Return id
 

POST Value:

A common example is to create new entry after submission of HTML form. appRain code save all post date in $this->data variable if we submit POST value and element has "data" in the name. See bellow example:
 
HTML

<form method="post" action="<?php echo App::Config()->baseUrl("/page/manage");?>" >
    <input type="data[Information][name]" value="" />
    <input type="data[Information][title]" value="" />
    <input type="data[Information][description]" value="" />
</form>
 
PHP

if(!empty($this->data)){
 
    $obj = $this->InformationSet('Post')->Save($this->data));
    $error = $obj->getErrorInfo();

 
    if (!empty($error)) {
        App::Module('Notification')->Push($error,'error');
    }
    else {
        App::Module('Notification')->Push("Saved Successfully");
    }
}
