Formatting columns in a table - El Forum - 03-09-2011

I'm pulling data from a database then outputting it in an HTML table. That part's fine. But what I can't figure out is how to apply formatting to the individual columns in the results.
So, the first column is a part number, then a product name, then a price, etc. I want to format the price column as money (applying the money_format() or similar function).
My controller:
Code:
// call my model's function to grab the data:
$data['results'] = $this->productsmodel->get_products();
// load the HTML Table Class
$this->load->library('table');
$this->table->clear();
$this->table->set_heading('Part #', 'Name', 'List price', 'Parts', 'Hours', 'Total');
$this->template->set('title','Products');
$this->template->load('template','products', $data);And my view:
Code:
echo $this->table->generate($results);Works fine but how can I format columns? I tried manually adding rows with $this->table->add_row() but I can't figure out how to extract the data returned by my model. BTW, it's just calling $query = $this->db->get('parts'); I could do the formatting with jQuery but there are a lot of rows and that would be slow I'm guessing.
Thanks,
Tim

Well, you could do it in MySQL(if the is what DB you are using). Or you could use a template, or you could prepare the data before you pass it to the generate method.

I guess it's the "prepare the data before you pass it to the generate method" that I figured was the best way. But that's what I can't figure out. I never thought about using MySQL, but you're right -- CONCAT('$', FORMAT(mynumberfield, 2))
I'd still like to know how to do the "prep the data" technique.

You can add a css class to the table! You need to use the Table Classes table template.
Code:
class MY_Controller extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->library('table');
$tmpl = array (
'table_open' => '<table border="0" cellpadding="4" cellspacing="0">',
'thead_open' => '<thead>',
'thead_close' => '</thead>',
'heading_row_start' => '<tr>',
'heading_row_end' => '</tr>',
'heading_cell_start' => '<th>',
'heading_cell_end' => '</th>',
'tbody_open' => '<tbody>',
'tbody_close' => '</tbody>',
'row_start' => '<tr>',
'row_end' => '</tr>',
'cell_start' => '<td>',
'cell_end' => '</td>',
'row_alt_start' => '<tr class="alt">', // See class added here!
'row_alt_end' => '</tr>',
'cell_alt_start' => '<td>',
'cell_alt_end' => '</td>',
'table_close' => '</table>'
);
$this->table->set_template($tmpl);
}
}I am using a MY_Controller but should work in a regular Controller.
For formatting you can use the php sprintf method.

Thanks, adding a class as you showed would help me format rows. But I need to format the content in the third column. I don't see how that can be done with the table templates.
As for the printf function, how do I apply it to the third column of data using the table library?

Can you show your view code.

Sure, it's really just the table->generate call. The rest is just HTML/CSS to pretty it up.
Code:
<div class="button" style="width:150px;float:right;margin-right:20px;"><a href="import" title="Import new prices">Import new prices</a></div>
<br clear="all"/>
<div class="dashstats">
<div class="dsTitle"><span id="mProducts"> </span>Products</div>
<div class="dsBody" id="partstable"><br clear="all"/>
<?php
echo $this->table->generate($results);
?>
</div>
</div> <!-- // end .dashstats -->
<script type="text/javascript">
$(document).ready(function(){
$("#partstable tr").mouseover(function(){$(this).addClass("over");}).mouseout(function(){$(this).removeClass("over");});
$("#partstable tr:even").addClass("evenTR");
});

to format the your column you would need to loop through the returned result set either in your model or your controller.
Code:
$data['results'] = $this->productsmodel->get_products();Then you could format the fields you need formatted.

When I print_r($results) in my view, this is what I get:
Code:
CI_DB_mysql_result Object ( [conn_id] => Resource id #27 [result_id] => Resource id #42
[result_array] => Array ( ) [result_object] => Array ( ) [custom_result_object] =>
Array ( ) [current_row] => 0 [num_rows] => 145 [row_data] => )What do I loop over within that to access the data? Or are you saying I need to dispense with the automated techniques offered with the Table library and build my own? I'm certainly familiar with PHP enough to query a DB, loop through a result set, and output an HTML table. What I'm trying to figure out is what & how CI can do the heavy lifting for me. The automated table-building library is a great timesaver. I just figured there was some callback or other means built-in for me to manipulate rows and columns prior to output. It seems not, so I'll go the roll-my-own route.
I don't mean that to be snotty. And I really appreciate your help! If there's not a built-in way to do what I want, I'm fine with doing it more manually. I'm just trying to learn the CI way (since I obviously have not used it very much).
Thanks,
Tim
