Change template

May I ask why you would want to do this? I don’t see the added value of inserting a span here. Or do you want to change more?

Anyway, if you want to change something in the template, you’ll have to completely reconstruct the template in your callback function by copying the code from the plugin and then making your changes before you return the output. Like so:

$row_template = '<tr class="%current_user_css_class%">
			<td><a href="%user_url%">%user_name%</a></td>
			<td class="home">%home_score%</td>
			<td class="match-hyphen">-</td>
			<td class="away">%away_score%</td>';
if ( $pool->has_jokers ) {
	$row_template .= '<td title="%joker_title_text%"><div class="nopointer %joker_css_class%"></div></td>';
}
$row_template .= '<td class="score"><span class="user_score">%score%</span></td></tr>';

return $row_template;

Or, if the changes are small and no other logic is needed, you can sometimes simply do a text replace. Like I do in this example.

Hope this helps.

One note: in my next version of the plugin I will have a small update to this row template. So, when you upgrade, please make sure you compare your extension output with my new version (or you may miss some new features).

Well it is not only the span with class I need to insert there…

Even though the string replace function seems OK for other functionalities, in this one I need to introduce other changes in the template which are mainly for styling reasons.

However, it has now came to my attention that I would like to also change the template html start and introduce <thead> after the <table> and make the th elements part of the <thead> element.
In this way I can use the “table sorter” plugin which requires that thead is correctly declared in the table structure.

In order to achieve the above I suppose I don’t need an football pool extension plugin rather I can use a PHP snippet to do so right ? Would you be able to provide the code I a looking for ?

Thank you

Not sure what you mean by PHP snippet, but extending my plugin is done by hooking into filters or actions. My preferred way of doing this is by creating an extension (because those can be easily enabled or disabled, and it’s easier to spot what changes you’ve done). But that is just one method to get it done. You can also include the code in your theme’s functions.

I can help you by giving a ‘canvas’ that you can work with. Will spend some time during tonight’s games.

Might as well do it straight away. This example code will do nothing if you don’t change it. It will simply return the same template. But if you build up your $template vars in the corresponding functions in the way that you would like your html output, then you have what you need.

Hi Antoine

regarding placing the code in an extension (plugin) or in functions.php, we are on the same track. For testing purposes i am using the functions.php method, but the final product will be an extension as you prefer.

Now regarding the code, this is what I ended up doing, however I am 100% sure that the code can be improved. For example the $pool variable should be global and available to template_start, template_row.

Also i am not sure if the $match_info is already available or what I am doing is correct i.e. define the same logic [SQL query] as yours to get the $match_info details.

Nevertheless, see my working code below, and feel free, should you have enough time, to make edits.

Thank you in advance

Didn’t test it, but I think you can indeed simplify the template_start function. The query and data set is not needed. So something like this:

    public static function template_start( $template_start, $match_info ) {
        global $pool;
        $layout_class = $pool->match_table_layout === 0 ? 'classic-layout' : 'new-layout';
        $template_start = sprintf( '<style>
                                        table.tablesorter thead tr th {border:0;}
                                    </style>
                                    <table class="matchinfo match-%d %s statistics tablesorter">
                                        <thead>
                                            <tr>
                                                <th class="custom-username">%s</th>
                                                <th colspan="%d" class="custom-prediction sortless">%s</th>
                                                <th class="custom-score">%s</th>
                                            </tr>
                                        </thead>'
            , $match_info['id']
            , $layout_class
            , __( 'name', 'football-pool' )
            , ( $pool->has_jokers ? 4 : 3 )
            , __( 'prediction', 'football-pool' )
            , __( 'score', 'football-pool' )
        );
        return $template_start;
    }

Hi Antoine

this works as expected so once again thank you.
