Question

我正在使用wordpress网站，我只是坚持一个SQL查询。

我需要从数据库表中获取包含相同用户ID的值。

这是我的表：

当我在mysql中运行select查询时，它获取的结果是正确的：

但我不知道如何在我的php模板中获得此结果。

这是我在php中使用的查询：

$current_user = wp_get_current_user(); 
    $id=$current_user->ID;
    $skill1 =mysql_query("SELECT Skills FROM wp_candidate_skills WHERE user_id='{$id}' ");

我无法使用get-＆gt;结果，因为它显示的错误是get-＆gt;结果必须包含对象。像这样的错误是。

这是我在Mysql_query之后使用的：

$arr = mysql_fetch_array($skill1);
  print_r($arr);

输出为：

Wordpress代码：

public static function init_fields() {
        if ( self::$fields )
            return;
$current_user = wp_get_current_user(); 
    $user = $current_user->user_login;
    $useremail =  $current_user->user_email;
    $id=$current_user->ID;
$skill1 =mysql_query("SELECT ID,user_id,Skills FROM wp_candidate_skills WHERE user_id=$id"); 
$skill_note = mysql_fetch_array($skill1);
$result = mysql_query("SELECT * FROM wp_candidate_details WHERE user_id='{$id}' LIMIT 1"); 
$expe_note = mysql_fetch_assoc($result);
$job_title = $expe_note['job-cat1'];
$user_loc = $expe_note['location_one_id'];
$row_num = mysql_query("SELECT COUNT(Skills) FROM wp_candidate_skills WHERE user_id='{$id}' " );
$row_cnt = mysql_fetch_array($row_num);
$arr = mysql_fetch_array($skill1);
print_r($arr);
mysql_free_result($skill1);
    $skill_area = $skill_note['Skills'];

帮帮我们！感谢

Answer 1

试试这段代码，`$ skill1 = $ wpdb-＆gt; get_results（“SELECT ID，user_id，Skills FROM wp_candidate_skills WHERE user_id ='$ id'”）;

        $count = count($skill1);
        $array = array();
        foreach ($skill1 as $key => $value) {
            $sk = $value->Skills;
            $array[] = $sk;
        }

        $fixId =array();
        $fixId[0] ='';
        for($i=0;$i<=$count-1;$i++)
        {
            $temp = $array[$i];
            $fixId[0] = $fixId[0].$temp.',';
        }
        $data = $fixId[0] ;
        $words = array_filter(preg_split('/\s*,\s*/', $data));
        $temp = implode(', ', $words);`

它将数据作为一个数组获取，并在两个值之间插入逗号。

Answer 2

使用get_results，如下所示：

<?php

    global $wpdb;   //important  

    $result = $wpdb->get_results("SELECT Skills FROM wp_candidate_skills WHERE user_id='$id' ");  

    foreach($result as $row)
    {    
        echo $row->Skills."<br>";    
    }

Display mysql table data in a wp page

Answer 3

试试这种方式

$current_user = wp_get_current_user(); 

$id=$current_user->ID;

$skill1 =mysql_query("SELECT Skills FROM wp_candidate_skills WHERE user_id='".$id."' ");

$arr = mysql_fetch_array($skill1);

print_r($arr);

Answer 4

使用以下代码：

public static function init_fields() {
        if ( self::$fields )
            return;

    global $wpdb;
    $current_user = wp_get_current_user(); 
    $user = $current_user->user_login;
    $useremail =  $current_user->user_email;
    $id=$current_user->ID;

    $result = $wpdb->get_results("SELECT ID,user_id,Skills FROM wp_candidate_skills WHERE user_id=$id");

    print_r($result);
    die();
}
