[PHP] Issues Displaying a League Table

19,667 · December 11

Hi all,

Please see the following documentation for reference: https://secure.rugby-league.com/api/docs/

A developer provided me with the following PHP file (although I have removed the API key and Secret):

/**
 * League Championships
 */

function fetch_league_table() {
    // Replace with your actual API credentials
    $apiKey = 'xxxx';
    $secret = 'xxxx';

    // Generate a digital signature (sig) using the current timestamp
    $timestamp = time();
    $sig = hash_hmac('sha256', $timestamp, $apiKey . $secret);

    // API endpoint and query parameters
    $apiUrl = 'https://secure.rugby-league.com/api/leaguetable';
    $queryParams = [
        'compID' => 4, // Replace with the appropriate competition ID
        'sig' => $sig
    ];

    // Build the full URL
    $urlWithParams = $apiUrl . '?' . http_build_query($queryParams);

    // Initialize cURL
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $urlWithParams);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, [
        'Accept: application/json',
        'x-api-key: ' . $apiKey,
        'sig: ' . $sig
    ]);

    // Execute the API request
    $response = curl_exec($ch);

    // Check for errors
    if (curl_errno($ch)) {
        return 'Error fetching data: ' . curl_error($ch);
    }

    curl_close($ch);

    // Decode JSON response
    $data = json_decode($response, true);

        // Handle response and build HTML output
    if ($data['status'] !== 200) {
        return 'No data found.';
    }

    $leagueTable = $data['data']['table'];

    $output = "<h2>" . $data['data']['competition'] . " - " . $data['data']['season'] . "</h2>";
    $output .= "<table border='1' cellpadding='5' cellspacing='0'><thead><tr>";
    $output .= "<th>Position</th><th>Team</th><th>Played</th><th>Wins</th><th>Losses</th><th>Draws</th><th>Points</th></tr></thead><tbody>";

    foreach ($leagueTable as $position => $team) {
        if ($position === 'deductions') continue;
        $output .= "<tr>";
        $output .= "<td>" . $position . "</td>";

        // Fetch the logo URL from the API response
        $logoUrl = isset($team['logo']) ? $team['logo'] : '';
        $logoHtml = $logoUrl ? "<img src='$logoUrl' alt='{$team['teamName']} logo' style='height:20px; margin-right:10px;'>" : '';

        $output .= "<td><strong>" . $logoHtml . $team['teamName'] . "</strong></td>";
        $output .= "<td>" . $team['P'] . "</td>";
        $output .= "<td>" . $team['W'] . "</td>";
        $output .= "<td>" . $team['L'] . "</td>";
        $output .= "<td>" . $team['D'] . "</td>";
        $output .= "<td>" . $team['PTS'] . "</td>";
        $output .= "</tr>";
    }

    $output .= "</tbody></table>";

    // Display deductions if available
    if (isset($leagueTable['deductions'])) {
        $output .= "<h3>Deductions</h3><ul>";
        foreach ($leagueTable['deductions'] as $deduction) {
            $output .= "<li>" . $deduction['team'] . ": -" . $deduction['pts'] . " points (" . $deduction['reason'] . ")</li>";
        }
        $output .= "</ul>";
    }

    return $output;
}

add_shortcode('league_table', 'fetch_league_table');

This PHP file provides us with the table on the website, although I note that the year is 2019. I think this is because the Leaguetable API endpoint doesn't have a year integer. I have been told that I should be able to get the year integer from the Competitions endpoint. But I am not a PHP developer, and I think that the developer that gave me this code got it by going through an AI prompt (i.e. he doesn't know PHP either).

I can see the API endpoint in the code, so I would imagine that I copy that, paste it again but modify the URL and the queryparams to search for year. But what I don't know is how I would then put the query params together so that the table being displayed (compID 4) is for the current year (ex. 2024).

Would someone be able to assist me or point me in the right direction? I tried emailing the support email in the documentation but they have been less than helpful.

Many thanks in advance.

Without the API key and secret I'm not able to test anything, but according to the docs there is no "compID" parameter for the "leaguetable" endpoint, it should be "divisionID", so you're probably getting some kind of default value from 2019 (e.g. since divisionID is omitted it might be using 0)

Oh damn...that seems right. That would explain why it defaults...

I've received this bit of information since:

Quote

That league table call looks good, expect you only need to pass the division ID to the league table endpoint. See the docs.

To find the divisionIDs and seasonIDs you need to call the competitions endpoint using the relevant compIDs, which are:

Championship: 3
League One: 4
Challenge Cup: 2
1895 Cup: 115
Academy: 52

So the CompID is correct (4).

But now I don't know how to call the competitions endpoint as part of the code from the original post...like I said I'm no developer, especially with PHP. Do I try what I suggested at the start, copy-paste and modify the code for the competition part? But then if so, how do I concatenate the results from the first search and the second?

I've updated your code (well I used ChatGPT to update the code as 1. I haven't touched PHP since 2008 and I'm more than a little rusty, and 2. I'm not set up to run any PHP on this computer). You can now re-use the requestApi() function by passing the endpoint url and query params (use of it is shown in the fetch_league_table function).

/**
 * Reusable API request function

function requestApi($endpoint, $queryParams = []) {
    // Replace with your actual API credentials
    $apiKey = 'xxxx';
    $secret = 'xxxx';

    // Generate a digital signature (sig) using the current timestamp
    $timestamp = time();
    $sig = hash_hmac('sha256', $timestamp, $apiKey . $secret);

    // Add the signature to the query parameters
    $queryParams['sig'] = $sig;

    // Build the full URL
    $urlWithParams = $endpoint . '?' . http_build_query($queryParams);

    // Initialize cURL
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $urlWithParams);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, [
        'Accept: application/json',
        'x-api-key: ' . $apiKey,
        'sig: ' . $sig
    ]);

    // Execute the API request
    $response = curl_exec($ch);

    // Handle cURL errors
    if (curl_errno($ch)) {
        $error = curl_error($ch);
        curl_close($ch);
        return [
            'success' => false,
            'error' => "Error fetching data: $error"
        ];
    }

    curl_close($ch);

    // Decode JSON response
    $data = json_decode($response, true);

    // Check for decoding errors
    if (json_last_error() !== JSON_ERROR_NONE) {
        return [
            'success' => false,
            'error' => 'Error decoding JSON response.'
        ];
    }

    return [
        'success' => true,
        'data' => $data
    ];
}

/**

For the next step, how would you like it to work? Should it use the "competitions" endpoint to get a list of all "divisionID"'s for a particular (current) year, and then print all those? Is there just a particular divisionID you want displayed, etc?

Oh wow! Ok, that's great news! I've just performed a test and it still provides the table for 2019, but as you mentioned it's going to because it doesn't have the year parameter set.

I think you're right about the next step: display all DivisionID's for the current year. I haven't been provided with a specific DivisonID so I guess it would be all of them (at least for the moment)...

Wow, many thanks for taking a shot at this for me. I've been staring at the code for so long trying to understand it my eyes are getting crossed. :laugh:

@virtorioI meant to send you the keys earlier, I know I can trust you with them. My bad.

I'll send they keys in a moment, and I'll try the script on the server on my side once I read through it to try and see what is going on. (Y)

Seems like it was mostly correct, just needed to correct one array error and it wasn't handling invalid requests from the API properly.
