您好我目前在PHP中使用预编译语句的if语句有问题，无论我在检查get_result时输入的是什么，我的语句总是正确的。老实说，我不知道我在做什么，我对php和预备语句的概念很新。
$searchtext= $_POST['search-box'];
$sqlName= $connect->prepare("SELECT * FROM SearchPG WHERE PGName LIKE ? ");
$sqlName->bind_param("s", $searchtext);
$sqlName->execute();
$NameResult = $sqlName->get_result();
$sqltext= $connect->prepare("SELECT * FROM SearchPG WHERE PGKeywords LIKE ? ");
$sqltext->bind_param("s", $searchtext);
$sqltext->execute();
$TextResult = $sqltext->get_result();
if($NameResult->num_rows > 0 || $TextResult->num_rows > 0){
if($NameResult->num_rows > 0 ){
echo "made it into sqlname";
while($rs = $NameResult->fetch_assoc()){
echo "name result";
?>
<div class="row resultcontent">
<a href="<?php echo $rs['PGUrl'];?>">
<div class="col-sm-8 searchRsltCont">
<img src="<?php echo $rs['PGImgUrl'];?>" class="searchRsltimg" alt="search result image" />
<div class="contshading">
</div>
</div>
<div class="col-sm-4 searchRslttxt">
<h1><?php echo "name".$rs['PGName'];?></h1>
</div>
</a>
</div>
<?php
$count++;
}
}
if($count<10){
echo "exploded result";
foreach($searchbit as $value){
$temp = '%'.$value.'%';
$sqlvalue= $connect->prepare("SELECT * FROM SearchPG WHERE PGName LIKE ? OR PGKeyword LIKE ? ");
$sqlvalue->bind_param("ss", $temp, $temp);
$sqlvalue->execute();
$ValueResult = $sqlvalue->get_result();
if($ValueResult->num_rows > 0){
while($rs = $ValueResult->fetch_assoc()){
?>
<div class="row resultcontent">
<a href="<?php echo $rs['PGUrl'];?>">
<div class="col-sm-8 searchRsltCont">
<img src="<?php echo $rs['PGImgUrl'];?>" class="searchRsltimg" alt="search result image" />
<div class="contshading">
</div>
</div>
<div class="col-sm-4 searchRslttxt">
<h1><?php echo "name".$rs['PGName'];?></h1>
</div>
</a>
</div>
<?php
$count++;
}
}
}
while($rs = $TextResult->fetch_assoc()){
?>
<div class="row resultcontent">
<a href="<?php echo $rs['PGUrl'];?>">

我试过if（！$ result），if（$ result-＆gt; num_rows＆gt; 0），if（$ result-＆gt; affected_rows）和其他但似乎没有工作有人知道我在做什么错
答案 0 :(得分：0)
你很有可能没有＆＃34;本地司机＆＃34; （mysqlnd）已安装，这是 OnePlayerFragment f = (OnePlayerFragment) getSupportFragmentManager().findFragmentByTag("OnePlayer");
方法所必需的。
比照http://php.net/manual/en/mysqli-stmt.get-result.php
尝试使用PDO：
get_result()答案 1 :(得分：0)
对于任何可能不熟悉php，准备好的语句和类似问题的人，我通过在更改代码以适应store_result之后将get_result切换到store_result来解决我的问题似乎完美无缺。这是我的新代码，它仍然需要一些修复和清理，但我希望这可以帮助有需要的人。
