Question

我在PHP中有一些关于MySQL的问题。

这是我的配置代码：

<?php

class Core{

    public $connect;

public function __construct(){
    $host = 'localhost';
    $user = 'root';
    $password = '';
    $database = 'fix';
    $this->connect = new mysqli($host,$user,$password,$database);
    if(!$this->connect) echo mysql_error();
    }

    public function siteTitle(){
    $title = "title";
    $tagline = "tagline";
    return $title. " - ".$tagline;
    }

    public function load($file,$data){
        extract($data);
        require "$file.php";
    }

    public function searchResult(){
        $query = $this->connect->query("SELECT * FROM `location`");
        if($query->num_rows > 0){
            $columns = $query->fetch_assoc();
            return $columns;    
        }
    }



    public function locationStatus($id){
        $location = $this->searchResult();
        $locationId = $location['id'];
        if($locationId == 1){
            echo "Available <i class='ui icon circle green'></i>";
        }elseif($locationId == 2){
            echo "Under Counstruction <i class='ui icon circle orange'></i>";
        }else{
            echo "Unavailable <i class='ui icon circle red'></i>";
        }

    }


}


?>

我将在searchResult.php文件中显示searchResult（）函数的结果：

      <div style='border:1px solid #ccc; padding:3px;'>
        <img src="asset/images/<?php echo "$data[image].jpg"; ?>" class='ui image medium' style='padding-right:10px;float:left' />
       <h2 style='font-family:nexa;color:rgb(36,162,217);line-height:0;'><?php echo $data['title']; ?></h2>
       <h4><span style='color:orange;'>Location Address: </span><?php echo $data['subtitle']; ?></h4>
       <p><?php echo $data['description']; ?></p>
       <br />
       <p>
       <i class='ui icon marker big orange'></i>Checkin: <?php echo $data['checkin']; ?> &nbsp;&nbsp;&nbsp;<i class='ui icon clock big orange'></i>Published at: <?php echo $data['published']; ?>&nbsp;&nbsp;&nbsp; Status: <?php echo $this->locationStatus($data['id']); ?>
       </p>
       <a style='' href='location/<?php echo $data['slug']; ?>' class='ui button blue'>READ MORE</a>

</div>

searchResult.php，我在Index.php中用代码：

调用它

<?php echo $this->load('templates/searchResult', $this->searchResult()); ?>

我的问题是：

为什么我的sql查询的结果不是循环？虽然，我用循环循环它？

感谢。对不起，如果我的语言不好。

Answer 1

如果您想像这样调用您的视图

<?php 
    echo $this->load('templates/searchResult', $this->searchResult()); 
?>

您必须将循环放在searchResult()方法中，以便这一次调用将返回所有行。

public function searchResult(){
    $query = $this->connect->query("SELECT * FROM `location`");

    $rows = array();

    if($query->num_rows > 0){
        while ( $row = $query->fetch_assoc() ) {
            $rows[] = $row;
        }
    }
    return $rows;    
}

然后在您的视图中，循环遍历$data

Answer 2

public function searchResult(){
    $query = $this->connect->query("SELECT * FROM `location`");
    if($query->num_rows > 0){
        while ($columns = $query->fetch_assoc())
        {
            $data[] = $columns;
        }
    }
    return $data;
}

你需要在searchResult函数中使用while循环。

如何在函数中返回mysql_fetch_array
