PHP json_encode() Data Types, Quotes

[beardmcbob]

I'm programming a dynamic Grid. I use PHP's json_enode() to pass the ColumnModel options. Now, I would also like to pass a renderer. My definition in PHP looks something along the lines of:

$colModel = array(
    array(
        'id' => 'icon',
        'header' => 'Icon',
        'width' => 40,
        'dataIndex' => 'icon',
        'renderer' => renderIcon, // where renderIcon would be the rendering function
    ),
    array(
        'id' => 'nr',
        'header' => 'Nr',
        'dataIndex' => 'nr',
        'width' => 200,
    ),

    ...

);

json_encode( $colModel ); 

On the client side I get the data from PHP with a Ext.data.Connection. This gets passed to the grid's ColumnModel:

...

var cm = Ext.decode( response.responseText );

var colModel = new Ext.grid.ColumnModel(cm); 

My problem is, that PHP's json_encode() converts the value of "renderer" to a string:

...
{"id":"icon","header":"Icon","width":40,"dataIndex":"icon","renderer":"renderIcon"}
...

In the column definition, however, it needs to appear WITHOUT quotes. Does anyone have an idea how this can be done?

Thanks!!

Try this:

$json_encoded_colModel = str_replace ('"renderIcon"', 'renderIcon', json_encode( $colModel ));

I got that far too... but that can't really be the point?! Isn't there a better way to do this?

$json_encode1 = str_replace ('"[', '', json_encode($this->list));
$json_encode = str_replace (']"', '', $json_encode1);



$combo['combo']['renderer'] = '[function(){}]';
