PHP警告:mysql_query()期望参数1为字符串

Question

可能重复:
mysql_fetch_array()期望参数1是资源,在select中给出boolean

希望你们中的一个能快速完成.

我收到两个与以下内容相关的错误:

警告:mysql_query()期望参数1为str​​ing,给定数组

我的代码如下......

 <?php
#
#  FUTURE EVENTS

# PAGE SELECTOR FUNCTION
function pageselector ($pagenum, $pages, $arg, $perpage) {
  #page we're loading
  if (!$pagenum) $pagenum=1;
  # PRINT PAGE SELECTOR
  $pages=ceil($pages/$perpage);
  #last = prev page unless we're already at page 1
  if ($pagenum==1) {$last=1;}     else {$last=$pagenum-1;}
  #next = next page unless we have no more pages to display
  if ($pagenum==$pages) $next=$pagenum;     else $next=$pagenum+1;
  #create page numbers
  $pagenumbers="";
  for ($i=1; $i<=$pages; $i++) {
      if ($i==$pagenum)
          $pagenumbers.=$i.' ';
      else
      $pagenumbers.="<a href=\"?pagenum=$i$arg\">$i</a> "; 
        }
  # create page num in case of blank page
  if (!$pagenumbers) {
    $pagenumbers="<a href=\"?pagenum=1$arg\">1</a> "; 
      }
print <<< pageSelector
<div class="pageselector">

$pagenumbers
<a href="?pagenum=$next$arg">&rsaquo;</a> <a href="?pagenum=$pages$arg">&raquo;</a>

  return $pagenum;
  }


$perpage=3;
$now=time()-(1 * 24 * 60 * 60);
$sql="SELECT count(*) AS total FROM event_tbl WHERE dates>'$now'";
$sql=mysql_query($sql);

$pagenum=pageselector ($pagenum, $sql['total'], '', $perpage);

$eventlist=array();
$sql="SELECT * FROM event_tbl WHERE dates>'$now' ORDER BY dates ASC";
$sql=mysql_query($sql);
$sql=mysql_fetch_array($sql);
while ($sqlevent=mysql_query($sql)){
  $eventlist[]=$sqlevent['id'];
    }

for ($i=0; $i<$perpage; $i++) {
  $tempid=($perpage*($pagenum-1))+$i;
  $sql="SELECT * FROM event_tbl WHERE id='$eventlist[$tempid]'";
  $sql=mysql_query($sql);
  $smallevent=mysql_query($sql);
    if ($smallevent['dates']==0)
      break;
  print '<div>';
    $smallevent['description']=strip_tags($smallevent['description'], '<img>');
  $shortdescription=substr($smallevent['description'], 0, 350);
  print '<span style="font-size: 14px;"><b><a href="./event.php?event='.$smallevent['id'].'">'.$smallevent['name'].'</a></b> - <b>Date:</b> '.date('j/n/Y', $smallevent['dates']).' - <b>Price:</b> ';
    $places=$smallevent['placesavailable']-$smallevent['placesbooked'];
    if ($places>0)
    print '&pound;'.$smallevent['price'].'<br />';
  else 
    print '<span class="soldout">SOLD OUT</span><br />';
    print '</span><br />';
    print $shortdescription.'...';
    print '<br /><br />';
    print '<a href="./tellfriend.php?event='.$smallevent['id'].'"><img src="./images/link-tellfriend.png" alt="" /></a> &nbsp;';
    print '<a href="http://maps.google.com/maps?daddr='.$smallevent['postcode'].'" target="_blank"><img src="./images/link-directions.png" alt="" /></a> &nbsp;';
    print '<a href="./event.php?event='.$smallevent['id'].'"><img src="./images/link-info.png" alt="" /></a> &nbsp;';
    if ($smallevent['bookless']==0 & $places>0)
      print '<a href="./bookevent.php?event='.$smallevent['id'].'"><img src="./images/link-book.png" alt="" /></a> ';
    print '</div><br /><br />';
    }
?>

两条错误行是:

while ($sqlevent=mysql_query($sql)){  
$eventlist[]=$sqlevent['id'];   }

$smallevent=mysql_query($sql);

我有一个DB Connect文件(虽然不确定它是否触发？)

任何帮助赞赏.

干杯

Answer 1

$eventlist=array();
$sql="SELECT * FROM event_tbl WHERE dates>'$now' ORDER BY dates ASC";
$sql=mysql_query($sql);
$sql=mysql_fetch_array($sql);
while ($sqlevent=mysql_query($sql)){
  $eventlist[]=$sqlevent['id'];
}

错误很清楚.出于某种原因(我不知道是什么),你mysql_query 再次使用数组调用.

也许你的意思是:

$eventlist=array();
$sql = "SELECT * FROM event_tbl WHERE dates > '$now' ORDER BY dates ASC";
$res = mysql_query($sql);
while ($sqlevent = mysql_fetch_array($res)) {
  $eventlist[] = $sqlevent['id'];
}
