mysql_fetch_array（）预计参数1是资源，布尔在选择

Question

可能重复给出：
mysql_fetch_array() expects parameter 1 to be resource, boolean given in select
Warning: mysql_fetch_* expects parameter 1 to be resource, boolean given error

我试图从表中选择数据，但得到这个错误信息！！

mysql_fetch_array（）预计参数1是资源，布尔我使用分页在PHP实际上是在选择

给...但它工作得很好了简单的查询与仅在单个条件.. 。但在这里......有多个条件，它不工作 完整的代码是：

    /*

    */

mysql_select_db("database",$con);

    $tbl_name="posts";  //your table name 
    // How many adjacent pages should be shown on each side?

什么问题？

Answer 1

mysql_query返回false上failur

Answer 2

不知道哪里出错，但你可以尝试做的是财产以后这样的：

$sQuery_select_stuff = " SELECT * FROM stuff WHERE stuff_id = 1"; 
$rResultaat_select_stuff = mysql_query($sQuery_select_stuff) or die(mysql_error()); 
$total_pages = mysql_fetch_array($rResultaat_select_stuff); 

Answer 3

回声出你的$ query变量，看是否它你期望它是

$query = $_GET['query']; 
$query = htmlspecialchars($query); 
$query = mysql_real_escape_string($query); 
echo $query;
