Question

我正在處理我的項目，我想從job_list中獲取來自tablesite + job_name的姓名，家庭，電話號碼和電子郵件以及來自關係的評論。這是我的代碼：

<fieldset class="fdex" > 
     <legend><span class="style4">لیست مشاغل</span></legend> 


     <?php 

$db_host = 'localhost'; 
$db_name= 'site'; 
$db_table= 'tablesite'; 
$db_user = 'root'; 
$db_pass = ''; 




$con = mysql_connect($db_host,$db_user,$db_pass) or die("خطا در اتصال به پايگاه داده"); 
$selected=mysql_select_db($db_name, $con) or die("خطا در انتخاب پايگاه داده"); 
mysql_query("SET CHARACTER SET utf8"); 

$dbresult=mysql_query("SELECT tablesite.name, 
          tablesite.family, 
          tablesite.phone_number, 
          tablesite.email, 
          job_list.job_name, 
        FROM $db_table 
        INNER JOIN relation 
        on tablesite.id_user=relation.user_id 
        INNER JOIN job_list 
        on relation.job_id=job_list.job_id",$con); 

while($amch=mysql_fetch_assoc($dbresult)) 
{?> 

<?php 
echo "* نام: "."&nbsp&nbsp&nbsp".$amch["tablesite.name"]." ".$amch["tablesite.family"]."&nbsp&nbsp&nbsp"."* عنوان خدمت: ".$amch["job_list.job_name"]."&nbsp&nbsp&nbsp"."* شماره تماس: ".$amch["tablesite.phone_number"]."&nbsp&nbsp&nbsp"."* ایمیل: ".$amch["tablesite.email"].'<br>' 
.$amch["relation.comments"].'<br>'; 

} 
?> 

</fieldset> 

當我運行的代碼，我有錯誤：

Warning: mysql_fetch_assoc() expects parameter 1 to be resource, boolean given in C:\wamp\www\source\JobList.php on line 259

行259：

while($amch=mysql_fetch_assoc($dbresult)) 

tablesite：id_user，姓名，家庭，PHONE_NUMBER，電子郵件

job_list：job_id，job_name

關係：JOB_ID，USER_ID評論

你的查詢有原位缺口需要，請更新您的查詢到這一個額外的逗號：

SELECT tablesite.name, 
         tablesite.family, 
         tablesite.phone_number, 
         tablesite.email, 
         job_list.job_name //<--it was here 
       FROM $db_table 
       INNER JOIN relation 
       on tablesite.id_user=relation.user_id 
       INNER JOIN job_list 
       on relation.job_id=job_list.job_id 

也不需要在你的PHP來指定表名：

<?php 
echo "* نام: "."&nbsp&nbsp&nbsp".$amch["name"] 
."  ".$amch["family"]."&nbsp&nbsp&nbsp"."* عنوان خدمت:" 
.$amch["job_name"]."&nbsp&nbsp&nbsp"."* شماره تماس:" 
.$amch["phone_number"]."&nbsp&nbsp&nbsp"."* ایمیل:" 
.$amch["email"].'<br>'.$amch["comments"].'<br>'; 

} 
?>
