MySQL查询仅循环一次

Question

My php function only retrieves and echos one piece of information. As I added a limit of 30, it should echo 30 times with different sets of info.

The webpage I am trying to edit is available at the following: http://rocketleaguelobby.com/?key=65d9c17e957870ee15161959b2c1dedb&p=/matches

My PHP Code:

<?php
// Connect to the database //
require_once($_SERVER['DOCUMENT_ROOT'].'/inc/dbconnect.php');

// Send the Query //
$query = "SELECT * FROM  `bets` WHERE `public` = '1' ORDER BY `betTime` LIMIT 0 , 30";
$result = mysqli_query($connection, $query);

if (mysqli_num_rows($result) == 0) {
    // If no results were found //
    echo '<span style="font-style: italic;opacity: 0.8;">No Bet History Found</span>';
} else {
    // Echo each bet history found //
    while($bet = mysqli_fetch_assoc($result)) {
        // For every bet, get info about the user //
        $query = "SELECT `steamName`, `steamAvatar` FROM `users` WHERE `steamID` = '".$bet['steamID']."' LIMIT 1";
        $result = mysqli_query($connection, $query);
        while ($user = mysqli_fetch_assoc($result)) {
            $query = "SELECT `teamShort` FROM `teams` WHERE `id` = '".$bet['betTeam']."' LIMIT 1";
            $result = mysqli_query($connection, $query);
            $betTeam = mysqli_fetch_assoc($result);
            $timeAgo = time() - $bet['betTime'];
            if ($timeAgo < 60) {

My JavaScript/jQuery Code:

$("#betHistory").load('/inc/getBets.php');

I am trying to get the previous 30 bets which you should be able to see on my website link I sent.

Right now it only echos 1 previous bet when in the database there are multiple bets already.

Answer 1

You have multiple $result = statements. The second and third statements are replacing the contents of the earlier statements. Change them to different names such as $result1, $result2, and $result3 and that should fix your problem.

You can also try print_r($bet); and print_r($user); in the appropriate parts of your program to see what is getting put in those variables.

Answer 2

You did use the $result for each query. By using a separate variable for each query you're problem will be solved.

I updated you're code according:

<?php
// Connect to the database //
require_once($_SERVER['DOCUMENT_ROOT'].'/inc/dbconnect.php');

// Send the Query //
$query = "SELECT * FROM  `bets` WHERE `public` = '1' ORDER BY `betTime` LIMIT 0 , 30";
$betsResult = mysqli_query($connection, $query);

if (mysqli_num_rows($betsResult) == 0) {
    // If no results were found //
    echo '<span style="font-style: italic;opacity: 0.8;">No Bet History Found</span>';
} else {
    // Echo each bet history found //
    while($bet = mysqli_fetch_assoc($betsResult)) {
        // For every bet, get info about the user //
        $query = "SELECT `steamName`, `steamAvatar` FROM `users` WHERE `steamID` = '".$bet['steamID']."' LIMIT 1";
        $usersResult = mysqli_query($connection, $query);
        while ($user = mysqli_fetch_assoc($usersResult)) {
            $query = "SELECT `teamShort` FROM `teams` WHERE `id` = '".$bet['betTeam']."' LIMIT 1";
            $teamsResult = mysqli_query($connection, $query);
            $betTeam = mysqli_fetch_assoc($teamsResult);
            $timeAgo = time() - $bet['betTime'];
            if ($timeAgo < 60) {
                // Seconds //
                if ($timeAgo >= 2) {
                    $timeAgo .= " Seconds Ago";
                } else {
                    $timeAgo .= " Second Ago";
                };
            } elseif ($timeAgo >= 60 & $timeAgo < 3600) {
                // Minutes //
                $timeAgo = round($timeAgo / 60);
                if ($timeAgo >= 2) {
                    $timeAgo .= " Minutes Ago";
                } else {
                    $timeAgo .= " Minute Ago";
                };
            } elseif ($timeAgo >= 3600 & $timeAgo < 86400) {
                // Hours //
                $timeAgo = $timeAgo / 60;
                $timeAgo = round($timeAgo / 60);
                if ($timeAgo >= 2) {
                    $timeAgo .= " Hours Ago";
                } else {
