creates an inplace editable html table from a database table. save this helper in your_project/lib/helper/input_in_place_editor_gridHelper.php dir

Special thanks to Christian.

There is a problem with saving the snippet here.I will try to update it later.

But for a normal (user interface) following action can be used:

public function executeUpdategrid()
{
    $value=trim(strip_tags($_POST['value']));// new value of the cell being updated
$pFieldValue=intval($this->getRequestParameter('pFieldValue'));// value of primary key of the record in the table, ie id value
$fieldNo=intval($this->getRequestParameter('fieldNo'));// index of the field coming from input_in_place_grid_tag
 
/*
to permit the fields just we want to update
here 2,3 and 4 are indexes of these fields in $rs, and this is for security
this is used only if secure parameter is set in grid options
*/
 
# these are just examples to illustrate secure usage
if($fieldNo==2)
$fieldName='Account.FIRSTNAME';
elseif($fieldNo==3)
$fieldName='Account.LASTNAME';
elseif($fieldNo==4)
$fieldName='Account.BIRTHD';
elseif($fieldNo==5)
$fieldName='Settings.EMAIL';
else
die("Invalid Table Field!");// invalid field number.(just for security.Complete table field names can be used in an admin application)
 
 
$split=explode(".",$fieldName);
$tableName=$split[0];
 
// to find primary key field name
$fields=call_user_func(ucfirst(strtolower($tableName)).'Peer::getFieldNames');
 
if($fields[0])
{
    # primary key field name
    $pFieldName=$tableName.".".strtoupper($fields[0]);
    # update corresponding field
    $conn=Propel::getConnection();
    $sql="UPDATE $tableName SET $fieldName='$value' WHERE $pFieldName=$pFieldValue";
    $conn->executeQuery($sql);
    $this->value=$value;// set the value to print out in the template "updategridSuccess.php"
}
else
$this->value=null;
}

or both can be used in same action as follows:

/**
 * account actions.
 *
 * @package    1insaat
 * @subpackage account
 * @author     Ahmet Ertek
 * @version    1.0
 * * @desc     Implements input_in_place_editor_grid helper's cell update.(this helper is not standart, just a custom helper).This action is not in use now.See /profile/templates/settingsSuccess.php

    $value=trim(strip_tags($_POST['value']));// new value of the cell being updated
    $pFieldValue=intval($this->getRequestParameter('pFieldValue'));// value of primary key of the record in the table, ie id value
    $fieldNo=intval($this->getRequestParameter('fieldNo'));// index of the field coming from input_in_place_grid_tag
    $fieldName=trim($this->getRequestParameter('fieldName'));// name of the field to be updated
    $fieldName=str_replace("_",".",$fieldName);// replace _ with. This is because no_script_name can be setto "on" in settings.yml of app

    */
    if(!$fieldName)
    {
        # these are just examples to illustrate secure usage, change these field names with yours
        if($fieldNo==2)
        $fieldName='Account.FIRSTNAME';
        elseif($fieldNo==3)
        $fieldName='Account.LASTNAME';
        elseif($fieldNo==4)
        $fieldName='Account.BIRTHD';
        elseif($fieldNo==5)

    }
 
    $split=explode(".",$fieldName);
    $tableName=$split[0];
 
    // to find primary key field name
    $fields=call_user_func(ucfirst(strtolower($tableName)).'Peer::getFieldNames');
 
    if($fields[0])
    {
        # primary key field name
        $pFieldName=$tableName.".".strtoupper($fields[0]);
        # update corresponding field
        $conn=Propel::getConnection();
        $sql="UPDATE $tableName SET $fieldName='$value' WHERE $pFieldName=$pFieldValue";
        $conn->executeQuery($sql);
        $this->value=$value;// set the value to print out in the template "updategridSuccess.php"
    }
    else
    $this->value=null;
 
}
?>

Note that to use this grid for admin app you may use

$options['secure']=>false;
