Hello there,

I was struggling to set default field values for the add form. So here's another suggestion for the grocery CRUD.

FILE: application/models/grocery_model.php
/* NEW */
protected $add_values = array();
   
/* NEW */
function set_add_value($field_name, $value) {
  $this->add_values[$field_name] = $value;
}

/* NEW */
    function get_add_values() {
  return (object) $this->add_values;
    }

FILE: application/libraries/grocery_crud.php
/* NEW */
public function getModel() {
  if($this->basic_model === null)
   $this->set_default_Model();
  return $this->basic_model;
}
/* NEW */
protected function get_add_values() {
  $values = $this->basic_model->get_add_values(); 
  return $values;
}
protected function showAddForm()
{
  $this->set_js('assets/grocery_crud/themes/datatables/js/jquery-1.6.2.min.js');
 
  $data	 = $this->get_common_data();
  $data->types   = $this->get_field_types();
  /* NEW */ $data->field_values = $this->get_add_values(null);
 
  $data->list_url   = $this->getListUrl();
  $data->insert_url  = $this->getInsertUrl();
  $data->validation_url = $this->getValidationInsertUrl();
 
  // OLD // $data->input_fields  = $this->get_add_input_fields();
  /* NEW */ $data->input_fields  = $this->get_add_input_fields($data->field_values);
 
  $data->fields    = $this->get_add_fields();
  $data->hidden_fields = $this->get_add_hidden_fields();
 
  $this->_theme_view('add.php',$data);
}

To set a default field value, you just do something like this:
$crud = new grocery_CRUD();
...
$crud->getModel()->set_add_value('order_date', date("Y-m-d"));
...
$crud->render();

Johnny, I know you have a lot of stuff to do, but could you think about it?

Hello Rafael,
Actually the problem that you will have with this is that everytime I have the add form and you press the button save. Then I have a JavaScript clearForm method to clear all the inputs (/assets/grocery_crud/themes/flexigrid/js/flexigrid-add.js at line 86). So if you like to add it to your project remember to have this in mind. A solution for this is to add some JavaScript to your code to make it work.

As for this it's good as idea but I have really lot of stuff to do, so I am not promising anything for the next versions. You can always fork the grocery crud project at git htub - https://github.com/s...is/grocery-crud and have a pull request if you want to share a code with the community and improve grocery crud's functionality

Thanks Johnny, you're right. So here's another approach:

File: assets/grocery_crud/themes/flexigrid/js/Flexigrid-add.js
$(function(){
...
$("#FormLoading").ajaxStart(function(){
  $(this).show();
});
$("#FormLoading").ajaxStop(function(){
  $(this).fadeOut('slow');
});

clearForm(); // NEW

$('#crudForm').submit(function(){
...
	    }
}
...
function clearForm() {
$('#crudForm').find(':input').each(function() {
  var default_value = $(this).attr('name') + '_default_value';
  try { var value = eval(default_value); } catch(err) {}

  switch(this.type) {
   case 'password':
   case 'select-multiple':
   case 'select-one':
   case 'text':
   case 'textarea':
    if (typeof(value) === 'undefined') {
	 $(this).val('');
    } else {
	 $(this).val(value);
    }
    break;
   case 'checkbox':
   case 'radio':
    if (typeof(value) === 'undefined') {
	 this.checked = Boolean(value);
    } else {
	 this.checked = false;
    }
  }
});

$('.remove-all').each(function(){
  $(this).trigger('click');
});
}

In my view, I have declared some javascript variables in order to define the default values for some fields. Like this:
<html>
...
<body>
<script type='text/javascript'>
var order_date_default_value = '2012-01-01';
var lenses_default_value = 'FAR';
</script>
...
<?php echo $output; ?>
...
</html>

As you can see above, there default values for two fields, the order_date and the lenses field.

What do you think about this solution?

I agree that the ability to set default values on forms is something that needs to be addressed to make groceryCRUD complete.

Actualy i do this using the callback_add_field function.


Example:

function example_callback_add_field(){
$this->grocery_crud->set_table('offices');
$this->grocery_crud->set_subject('Office');
$this->grocery_crud->required_fields('city');
$this->grocery_crud->columns('city','country','phone','addressLine1','postalCode');

$this->grocery_crud->callback_add_field('phone',array($this,'add_field_callback_1'));
$this->grocery_crud->callback_add_field('state',array($this,'add_field_callback_2'));

$output = $this->grocery_crud->render();

$this->_example_output($output);
}

function add_field_callback_1()
{
return '+30 <input type="text" maxlength="50" value="YOUR VALUE" name="phone" style="width:462px">';
}

function add_field_callback_2()
{
return '<input type="text" maxlength="50" value="YOUR VALUE" name="state" style="width:400px"> ( for U.S. only )';
}

We can use the default value saved in each field type, this modification require one line code modification

FILE: application/libraries/grocery_crud.php
protected function get_add_input_fields($field_values = null)
{
  $fields = $this->get_add_fields();
  $types  = $this->get_field_types();
  $input_fields = array();

  foreach($fields as $field_num => $field)
  {
   $field_info = $types[$field->field_name];
 
// OLD //    $field_value = !empty($field_values) && isset($field_values->{$field->field_name}) ? $field_values->{$field->field_name} : null;
/* NEW */  $field_value = !empty($field_values) && isset($field_values->{$field->field_name}) ? $field_values->{$field->field_name} : $field_info->default;
 


and when creating your table in SQL, change DEFAULT NULL with DEFAULT your_value

CREATE TABLE `mytable` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(25) DEFAULT NULL,
  `longtext` varchar(255) DEFAULT NULL,
  `icon` varchar(255) DEFAULT NULL,
  `isenabled` tinyint(1) DEFAULT '1',
  PRIMARY KEY (`id`)
) ;

everytime you create a new record, the field 'isenabled' will have 1 (true) as a default value

This can be done also with Database Forge Class
What do you think?

This is actually a good solution, but unfortunately $field_info->default does not exist in my implementation, so you may need to add it in grocer_crud_model.php -> get_field_types_basic_table() (or you can use your own model to override).

function get_field_types_basic_table()
    {
     $db_field_types = array();
     foreach($this->db->query("SHOW COLUMNS FROM `{$this->table_name}`")->result() as $db_field_type)
     {
     $type = explode("(",$db_field_type->Type);
     $db_type = $type[0];
     
     if(isset($type[1]))
     {
     $length = substr($type[1],0,-1);
     }
     else 
     {
     $length = '';
     }
     $db_field_types[$db_field_type->Field]['db_max_length'] = $length;
     $db_field_types[$db_field_type->Field]['db_type'] = $db_type;
     $db_field_types[$db_field_type->Field]['db_null'] = $db_field_type->Null == 'YES' ? true : false;
     $db_field_types[$db_field_type->Field]['db_extra'] = $db_field_type->Extra;
$db_field_types[$db_field_type->Field]['default'] = $db_field_type->Default;  // <------ DEFAULT FIELD
     }

Since the first post was made on 2011, I think this is no longer relevant.
So for anyone else look for such a solution, there is already a good news
grocerycrud field-type function already has "default value" as optional third parameter
http://www.grocerycr...ions/field_type

 

EDIT : this is only works for hidden, enum and set field


No-CMS homepage : http://www.getnocms.com
No-CMS forum : http://www.getnocms.com/forum
No-CMS Github page : https://github.com/g...diAsgard/No-CMS

 

Please don't mix up No-CMS and groceryCRUD issues.
(eg: user authentication etc is No-CMS specific issue and has nothing to do with groceryCRUD)

Actually, nothing works.
Grocery CRUD does not support default values (tell me if i am wrong).
I mean, there is something wrong with callback_before_insert.

If you make an invisible field to add action it is replicated to the edit action grid/form.

Is there any "workaround"?

I'm putting the varibles set to invisible, but it is not the better approach.

As this page[http://www.grocerycr...ons/field_type] says:
"
Note: The third parameter ($value) only works for the hidden, enum and set field and it is not a default value for all the other types.
"

Hi Folks,

 

Here's another approach - with NO Changes to the library.

 

 

I checked the library code to see what actually gets passed to the callback_field & callback_add_field callbacks when they are invoked.

 

Here's the line of code from application/libraries/grocery_crud.php:2416

 

 

 

 

$field_input = $field_info;
$field_input->input = call_user_func($this->callback_add_field[$field->field_name], $field_value, null, $field_info);
 

 


 

 

The thing I noticed is that there are three values being passed to the callback: $field_value, null and $field_info

So I prototyped my callback to receive all three and take a look whats in them (with var_dump)

 

Interesting ...here's my prototype:

 

 

 

function _cb_add_string_field($field_value, $dontcare, $field_info){
var_dump($field_value);
var_dump($dontcare);
var_dump($field_info)
return "<input id='field-MyFieldName' name='MyFieldName' type='text' value=\"we dont know yet\"/>";
}
 
 

 

 


The thing that interested me was the contents of $field_info, here's what was in there:

 

 

(object) {
->name (string) = "F_ID"
->type (string) = "int"
->default (NULL) =
->max_length (string) = "11"
->primary_key (integer) = 0
->db_max_length (string) = "11"
->db_type (string) = "int"
->db_null (boolean) = "false"
->db_extra (string) = ""
->required (boolean) = "false"
->display_as (string) = "Foreign Key  Index"
->crud_type (string) = "string"
->extras (string) = "What Have We Got Here??"
}
 

 

 

 


Look at the extras field - you wont see anything ... yet

all we need to do to see the text "What Have We Got Here??" in that extras field is this ...

In controller I added the following line :

 

 

$crud->field_type('F_ID', 'string', "What Have We Got Here??");
 

 

 

 


And Hey-Presto I have a default value to use in my callback.

 

So all I did in my controller is create a field type for an already existing field with a default value.

The field type doesn't seem to matter.

two lines of code and a REUSABLE callback prototype can give you your default values.

 

Here's my actual two lines of code:

 

 

 

$crud->field_type('F_ID', 'string', $F_ID);
$crud->callback_add_field('F_ID',array($this,'_cb_add_string_field'));
//also works with $crud->callback_field('F_ID',array($this,'_cb_add_string_field'));
 

 


 

 

Here's my actual callback:

 

 

function _cb_add_string_field($field_value, $dontcare, $field_info){
  $tmpl="<input id='field-%s' name='%s' type='text' value=\"%s\"  />";
  return sprintf($tmpl,$field_info->name,$field_info->name,$field_info->extras);
}

 

 

 

 

and if you want to display the values but still have them posted to the database (readonly)

 

 

 

$crud->field_type('F_ID', 'string', $F_ID);
$crud->callback_field('F_ID',array($this,'_cb_add_readonly_field'));
//also works with $crud->callback_add_field('F_ID',array($this,'_cb_add_readonly_field'));

 

 

 

 

and ..

 

 


function _cb_add_readonly_field($field_value, $dontcare, $field_info){
  $tmpl="<input id='field-%s' name='%s' type='hidden' value=\"%s\"  /><span>%s</span>";
  return sprintf($tmpl,$field_info->name,$field_info->name,$field_info->extras,$field_info->extras);
}
 
 

 

 


Now I hope this helps someone.

Also I would like the big boss to consider at the very least leaving this functionality as it is

OR

to give us this the field info as the default parameter

OR to give us a one-step solution

 

I suppose this could be done with Yet Another Subclass ..

 

I'll post a subclass soon.

 

I hope his helps someone .

 

Cheer's and thanks again for GroceryCrud

Hi Folks,

 

Here's the subclass I said I'd build

This will give you default values for the ADD Form

I've tested it a bit and it seems ok - I will be deploying this so if I

find any bugs I'll post fixes as I find them.

 

To use it - drop the subclass into the application/libraries folder

right beside grocery_crud.php

call the new file custom_grocery_crud.php

 

Edit application/controllers/examples.php

 

class Examples extends CI_Controller {

	function __construct()
	{
		parent::__construct();
		
		$this->load->database();
		$this->load->helper('url');
		
		//$this->load->library('grocery_Crud');	
		$this->load->library('custom_grocery_crud');	
	}

...

        function offices_management()
	{
		try{
			//$crud = new grocery_CRUD();
			$crud = new custom_grocery_crud();

			$crud->set_theme('datatables');
			$crud->set_table('offices');
			$crud->set_subject('Office');
			$crud->required_fields('city');
			$crud->columns('city','country','phone','addressLine1','postalCode');

			//our demo
                        $crud->field_set_defaults('city' , 'readonly', 'Hobart,Tasmania');

			$output = $crud->render();
			
			$this->_example_output($output);
			
		}catch(Exception $e){
			show_error($e->getMessage().' --- '.$e->getTraceAsString());
		}
	}

 

 

and run it - its that easy!

 

use field_set_defaults exactly the same way you would use field_type

 

Here's the subclass Attached File  custom_grocery_crud.php   7.28K   1353 downloads

 

and here it is inline for you to peruse:

Hi Folks,

 

Here's the subclass I said I'd build

This will give you default values for the ADD Form

I've tested it a bit and it seems ok - I will be deploying this so if I

find any bugs I'll post fixes as I find them.

 

To use it - drop the subclass into the application/libraries folder

right beside grocery_crud.php

call the new file custom_grocery_crud.php

 

Edit application/controllers/examples.php

 

class Examples extends CI_Controller {

	function __construct()
	{
		parent::__construct();
		
		$this->load->database();
		$this->load->helper('url');
		
		//$this->load->library('grocery_Crud');	
		$this->load->library('custom_grocery_crud');	
	}

...

        function offices_management()
	{
		try{
			//$crud = new grocery_CRUD();
			$crud = new custom_grocery_crud();

			$crud->set_theme('datatables');
			$crud->set_table('offices');
			$crud->set_subject('Office');
			$crud->required_fields('city');
			$crud->columns('city','country','phone','addressLine1','postalCode');

			//our demo
                        $crud->field_set_defaults('city' , 'readonly', 'Hobart,Tasmania');

			$output = $crud->render();
			
			$this->_example_output($output);
			
		}catch(Exception $e){
			show_error($e->getMessage().' --- '.$e->getTraceAsString());
		}
	}

 

 

and run it - its that easy!

 

use field_set_defaults exactly the same way you would use field_type

 

Here's the subclass attachicon.gifcustom_grocery_crud.php

 

and here it is inline for you to peruse:

I hope this actuall helps people - works for me.

 

 

Cheers everyone and thanks for Grocerycrud :)

This sounds interesting. I'll have a look later this week to see how it goes.

Hi again

 

I've made another enhancement to my subclass.

 

The facility to have dynamic where clauses.

 

here's an explanation :

 

Say I cave a catalogue item (table 1) that has images (table 2)

 

I want all my images - site wide - to be in my image table (table 2)

 

I may have other tables (collections) that have images

 

so clearly I need to have "image id" and "foreign_id" in my image table.

 

"Image id" identifies a unique image and "foreign_id" identifies a set of images.

 

I also have "collection_name" in my images table (table 2) so that I dont get any id collisions.

 

and I have an image title in the image table.

 

I also want to have an image id of my default image in the catalogue table

 

In this case my "foreign_id" would be the "catalogue_id" of my catalogue item.

and "collection_name" would be 'catalogue"

 

You still with me ??

 

so when I edit a catalogue item I want also to access a relationship 

show me all of the images in (table 2) where "collection_name" == 'catalogue' and "foreign_id" == "catalogue_id"

 

getting clearer??

 

we've all had to do this - in grocerycrud - using callbacks

 

because we cant set the "where part" in set_relation() to a value from the table in a controller

unless we do it in a callback - (which is fine - but this is easier)

 

so - to summarize:

 

when I edit a catalogue item - I want to be able to add images to it

I want to be able to set a default image

 

so what if for the above example we could do this :

 

for example:

   $crud->set_relation('Catalogue_Default_Image_id','Images','Images_Title',array('Images_Foreign_ID'=>'{Catalogue_ID}'));

 

The actual set_relation reads like this:

 

   $crud->set_relation('IMG_ID','Images','Title',array('F_ID'=>'{ID}'));

 

just like in the docs http://www.grocerycr...ns/set_relation

 

You can have as many fields you like to call from the other table and
the syntax is really simple. Just at the 3rd field you will have the
symbol { and } . So it will be for example:


 
$crud->set_relation('user_id','users','{username} - {last_name} {first_name}');
 

 

you can have the system replace values that are surrounded by curly braces "{}" in the where clause.

but ONLY in the value field - it doesnt make sense to change the key field at all.

 

 

so  example    $crud->set_relation('IMG_ID','Images','Title',array('F_ID'=>'{ID}','Image_Type'=>"Catalogue"));

 

and a row in the catalogue like this

 

ID=>2, IMG_ID->11, Text->'something about a catalogue item'

 

at run time the resulting where part would end up 

 

array('F_ID'=>'2','Image_Type'=>"Catalogue") 

 

Hope my explanation make sense to everyone

 

so here's my updated subclass

note -

I make the mods in a subclass so that I NEVER have to change the underlying library.

Also, I have to do some more reading to find out if I can do all this in a model which would take the hassle out of subclassing

 

I've also made some minor changes to the set_css and set_js functionality so that I can use them in my controller and other 

libraries.

 

anyway here you go - enjoy

 

its kinda big - hope thats ok  - maybe next time I'll just post a file

I've seen image crud.

 

I didn't need the extra complexity and I really don't like lookup tables in databases ( relation_n_n  )

 

Cheers and I will post a file next time
