How to display the same column twice or more ...

Hello,
For a special list, I need to do this :
In a mysql table, I have a column named 'parameters' which have a text like this
For id = 1 : parameters="param1=xxx;param2=yyy;param3=zzz"
For id = 2 : parameters="param1=aaaaaa;param2=bbbbb;param3=ddddd"
etc ...

I want to display those parameters in 3 differents colums :

----------------------------------------------------------------------
ID PARAM1 PARAM2 PARAM3
----------------------------------------------------------------------
1 xxx yyy zzz
2 aaaaaa bbbbb ddddd

My query needs to be like this : "select parameters as col1, parameters as col2, parameters as col3 from ....." for using PHP Functions :
col1:myfunction1($cell); --> Extract param1 value
col2:myfunction2($cell); --> Extract param2 value
col3:myfunction3($cell); --> Extract param3 value

How can I do this ?

Thanks

Hello graaooor,
I'm not a Chrono professional, but after checking your new post, I think that the following links may help:
How can I add a new column to a database table or change a column type?
P.S: I'm just an automated service😉

Hi graaooor,

You can use explode to convert the list back to an array:

<?php
$params = explode(';', $row['params']);
?>

!! Not tested !!

The individual params would then be in $params[0], $params[1], $params[2]

I'm not certain where exactly is the best place to do this.

Hi,

col2:return explode('=', explode(';', $row['params'])[1])[1];

You will need to change the first [1] based on the param number!

Not sure you understand what I want to do.
I work with virtuemart and I want to display the virtuemart_order_items for a particular order (here number 13410).
In debug mode I have :

SELECT 
`item`.`virtuemart_order_item_id` AS `item.virtuemart_order_item_id`,
. . .
`item`.`order_status` AS `item.order_status`,
`item`.`product_attribute` AS `item.product_attribute`,
`item`.`delivery_date` AS `item.delivery_date`, 
. . .
`item`.`locked_by` AS `item.locked_by` 
FROM `flex_virtuemart_order_items` AS `item` 
WHERE `item`.`virtuemart_order_id` = '13410' LIMIT 30

I want to do the same thing but like this :

SELECT 
`item`.`virtuemart_order_item_id` AS `item.virtuemart_order_item_id`, 
. . .
`item`.`order_status` AS `item.order_status`,
`item`.`product_attribute` AS `item.col1`, 
`item`.`product_attribute` AS `item.col2`, 
`item`.`product_attribute` AS `item.col3`,
`item`.`delivery_date` AS `item.delivery_date`, 
. . .
`item`.`locked_by` AS `item.locked_by` 
FROM `flex_virtuemart_order_items` AS `item` 
WHERE `item`.`virtuemart_order_id` = '13410' LIMIT 30

Then, I could call a different php function for each column (col1, col2 or col3) and extract each parameter separately .

The problem is how to associate virtuemart_attribute to col1, col2 and col3 ?

It should work fine using the first query, but you can use dummy fields names, in the columns list, use this:

Model.param1:title
Model.param2:title2
Model.param3:title3

and in the php functions:

Model.param2::return explode('=', explode(';', $row['product_attribute'])[1])[1];

Sorry, I don't understand what is Model.param1:title ... in your response.

A small example :
I have a mysql table with only 2 fields : ID and NAME.

I want to generate a list with id and name. It's ok for me.
The select is "SELECT model.ID,model.NAME from model.TABLE"

Now I want to generate a list with the ID, the NAME, and the NAME again.
The select is "SELECT model.ID,model.NAME AS COL1, model.NAME AS COL2 from model.TABLE"

How can I do that with CCV5 ?

under "Models" > Fields >

<?php
return array("model.ID", "model.NAME" => "COL1", "model.NAME" => "COL2");

I think this should do what you need!

Best regards,
Max

I try this :

Models / Fields :

<?php
return array("item.virtuemart_order_id", "item.order_item_sku","item.product_attribute" => "COL1","item.product_attribute" => "COL2","item.product_quantity");
?>

Front List / Columns List :
item.order_item_sku:PRODUIT
item.COL1:TF
item.COL2:CF
item.product_quantity:QTE

But the generated select is wrong :

Array
(
    [0] => SELECT `Extension`.`id` AS `Extension.id`, `Extension`.`name` AS `Extension.name` FROM `flex_chronoengine_extensions` AS `Extension` WHERE `Extension`.`enabled` = '1' ORDER BY `Extension`.`ordering` ASC
    [1] => SELECT `Connection`.`id` AS `Connection.id`, `Connection`.`title` AS `Connection.title`, `Connection`.`params` AS `Connection.params`, `Connection`.`extras` AS `Connection.extras`, `Connection`.`published` AS `Connection.published` FROM `flex_chronoengine_connections` AS `Connection` WHERE `Connection`.`title` = 'detailCommande' AND `Connection`.`published` = '1'
    [2] => SELECT COUNT(`item`.`virtuemart_order_item_id`) AS `item.count` FROM `flex_virtuemart_order_items` AS `item` WHERE `item`.`virtuemart_order_id` = '13410'
    [3] => SELECT `item`.`virtuemart_order_id` AS `item.virtuemart_order_id`, `item`.`order_item_sku` AS `item.order_item_sku`, `item`.`product_attribute` AS `item.COL2`, `item`.`product_quantity` AS `item.product_quantity` FROM `flex_virtuemart_order_items` AS `item` WHERE `item`.`virtuemart_order_id` = '13410' LIMIT 30
)

I have the item.product_attribute AS item.COL2 only.
There is nothing for COL1 !!!

I think this may not work in the current version without a core code change then, so I suggest that you simply process the value using the functions box, why do you need to get the same value under 2 columns names ? what do you want to do next ?

I work for a company which sell glasses.
The client who is logged on the website can choose a model, the size of the face, its color, the size of each branch and the color.
All these informations are stocked in the field product_attribute.

Everyday, a list must be create on all orders. This list specifie for each item order the model, the size, colours, ...

The list is like this :

model | size face | color face | size branches | color left branch | color right branch

Model is the field product_item_sku : No problem here.
The others ones ( size face | color face | size branches | color left branch | color right branch ) are stocked in the field product_attribute.

So I need to extract 5 differents informations, and create 5 columns to the list with only ONE field.
Its why I want to generate a select like :
select ...., product_attribute as col1, product_attribute as col2, ... col5 from ....
and use a php function for each one (col1, col2 ...) to extract for col1 the size of the face, col2 the colour of the face, ..,.

I don't know if it's clear but it's realy a problem for me to do this with CCV5.

Ok, we will do it with one field only, what do you have in the "columns list" box under your connection edit page now ?

Is it what you want to know ?

The result is like this :
I have nothing in the column name TF (COL1).

The select generated is :
SELECT `item`.`virtuemart_order_id` AS `item.virtuemart_order_id`, `item`.`order_item_sku` AS `item.order_item_sku`, `item`.`product_attribute` AS `item.COL2`, `item`.`product_quantity` AS `item.product_quantity` FROM `flex_virtuemart_order_items` AS `item` WHERE `item`.`virtuemart_order_id` = '13410' LIMIT 30

COL1 is not present !

If you get the data in the format you explained earlier then you could use this in the php functions box:

item.COL2:return explode(";", $cell)[0];

BUT, the image you have now show that you have a list in JSON format and you actually have the ids, not the text, there is no way to load this data in CCv5.

Sorry but you are wrong !
The problem is that the query is malformed.
If you simply replace Models / Fields by :

<?php
return array("item.virtuemart_order_id", "item.order_item_sku" => "PRD1", "item.order_item_sku" => "PRD2" );
?>

The query generated is wrong !

There is only the "AS PRD2" in the query. The first "AS PRD1" is omitted by CCV5 !

Ok, but the array value is simply not passed to the query, this is not a big issue, how the 2nd copy of the value can help the situation here ? you can do everything with the field value you load.

The problem is really that the array is not passed completly to the query and I don't know how to do.

Can you show me how to do this for this simple example : Display the column "item_order_sku" twice in the list.
The first column with the original string, the second inversed letters !

The list will be like this :
KIDI01 10IDIK

Hi graaooor,

I think that this condition won't work because you have two array keys that are the same.

array(
  "item.virtuemart_order_id", 
  "item.order_item_sku" => "PRD1", 
  "item.order_item_sku" => "PRD2" 
);

Hi Bob,
It's what I want !
I need to extract the same field twice, or more, with a alias ( "AS COL1", "AS COL2" for example), and apply a php function on each alias to do something different on each value..
It's impossible here because the query isn't generated correctly.

I used in the past a joomla component where I could write my own queries.
Infortunately, this component is définitaly abandonned since a few years. It was writted for a joomla 2.5.
I think that CFV5 is a good component, easy to use to display a simply list.
But when you want to do more complex things, It's really long to understand how to do, when it's possible !.
My question is, for me, simple : How to display a table field twice in the list.
A request like "select field_name as a, field_name as b from ..." isn't a common query, but in my case, it's a priority :
Write a php function to extract some informations with "a", and write another php function to extract other information with "b".

A suggestion for CCV5 would be for me to have a zone where I could write my own query and use all the others facilities offered with the rest of this component.
There is also a lack of examples, especially when you want to use both CFV5 and CCV5.

For example, I have a form with some research fields and, when the form is validated, I would display the result list using CCV5.
After a lot of research in the forum, I have succeed to show my list on the first page, but when I show the page 2, 3 ... the research fields are lost ! Why ? I don't know.
It will be a question in the forum when my post about display a field twice will be resolved !

showing the same field twice is easy and is just as I have explained earlier, assuming the field name is "field", just have this in the columns list:

model.field
model.field_copy

and in php functions

model.field_copy: return $row["field"];

Regards,
Max

Hello.
It's ok and it's works but the php function must be :

model.field_copy: return $row["model"]["field"];

Thanks a lot.

Graaooor
