我在 wordpress 网站上工作，我只是遇到了一个 sql 查询。
我需要从包含相同用户 ID 的数据库表中获取值。
这是我的 table :
当我在 mysql 中运行选择查询时，它获取的结果是正确的:
但我不知道如何在我的 php 模板中得到这个结果。
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}' ");
我不能使用 get->result 因为它显示 get->result 必须包含对象的错误。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($arr);
输出是:
WordPress 代码:
public static function init_fields() {
if ( self::$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，伙计们!谢谢
最佳答案
试试这个代码，`$skill1 = $wpdb->get_results("SELECT ID,user_id,Skills FROM wp_candidate_skills WHERE user_id='$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);`
它将获取数据作为数组，并在两个值之间插入逗号。
