Hi,

 

Currently the Flexigrid theme is exporting only the fields that are specified as columns in the table. How can I edit the functionality to export the all the table's fields?

 

Many thanks

This is obviously not optimal since it's messing with Grocery_CRUD.php, and pretty sure it's not tidy either, but in that file I basically changed the function calls from get_xxx to get_field_xxx. I duplicated the function with calls to get_columns to functions with calls to get_fields and renamed the duplicates get_field_xxx(). Finally I added get_fields() function.

 

There is probably a far more straightforward way to do this, and it'll be appreciated if someone can point me to how to a howto without editing grocery_crud.php

 

 

protected function exportToExcel($state_info = null)
	{
		$data = $this->get_common_data();
	
		$data->order_by 	= $this->order_by;
		$data->types 		= $this->get_field_types();
	
		$data->list = $this->get_field_list();
		$data->list = $this->change_field_list($data->list , $data->types);
		$data->list = $this->change_list_add_actions($data->list);
	
		$data->total_results = $this->get_total_field_results();
	
		$data->columns 				= $this->get_fields();
		$data->primary_key 			= $this->get_primary_key();
	
		@ob_end_clean();		
		$this->_export_to_excel($data);
	}

 

 

protected function get_fields()
	{
		if($this->columns_checked === false)
		{
			$field_types = $this->get_field_types();
			if(empty($this->fields))
			{
				$this->fields = array();

Why didn't you make a view (gc view) that shows all the fields and make a print out of it?

i am using this simple technique to achieve this

 

if ($this->uri->segment(3) == "export") {

$crud->columns('code','name','address','email','cell','phone','specialization','department','fees');

}

else{

$crud->columns('name','cell','email','phone');

      }

This is an old thread, but if someone still need a solution to get all the fields on export :

//segment 3 or 4 depending on your route config
		
if ($this->uri->segment(4) == "export") {

			$query = $this->db->query("select * from users");
			$string = [];
			foreach ($query->result_array() as $row)
			{
				foreach($row as $key=>$val){$string[]=$key;}
			}


			$crud->columns( $string);
		}
		else{
			$crud->columns('groups', 'first_name', 'last_name', 'birth','email','active');
		}
