Question

我想检查我的搜索字段是否为空，如果是，我会写出失败消息。由于某些原因，当我尝试在两个搜索字段中提交空值或将q2搜索字段留空时，以下代码不起作用。当我只在第一个字段中插入一个值时，它只会写出失败消息。希望你们能帮忙。

<div id="searchField">
    <form name="searchField" action="" method="get">
        <input type="search" name="q" id="submitQuery" autofocus="autofocus" value="<?= $_GET['q']; ?>" placeholder="enter one movie"/> 
        <input type="search" name="q2" id="submitQuery2" value="<?= $_GET['q2']; ?>" placeholder="and then another one"/> 
        <input type="hidden" id="v" name="v" value="2" />
        <input type="hidden" id="b" name="b" value="" />
        <button type="submit" id="loop" style="border:0px; background:transparent; vertical-align:middle; margin-left:-85px; margin-top:-3px;">
            <img src="images/loop.png" width="75" height="75" alt="submit" />       
        </button>
    </form>
</div>
<div id="theData">

<?
if(str_replace(" ", "",$_GET['q'])!="" && str_replace(" ","",$_GET['q2'])!=""){
    $qContent = $_GET['q'];
    $succes = mysql_query("SELECT*FROM film WHERE name='".$qContent."'");
    include("searchMaster.php");
    if(mysql_num_rows($succes)) {
        while($o = mysql_fetch_array($succes)){
            echo $o['name'];
            if($o['trailer']){
                echo '<div id="ytplayerWrap">';
                echo '<iframe id="ytplayer" type="text/html" width="640" height="390"
                src="http://www.youtube.com/embed/'.$o['trailer'].'?http://amnestic.ueuo.com"
                frameborder="0"/>';
                echo '</div>';
            }else {
                echo '<span style="font-size:20px;">';
                echo '<br /><br /> No trailer was found for <em>'.$_GET['q'].'</em> :(';
                echo '</span>';
            }
        }
    }else{
     echo 'You did the fuckup :(';
    }
}else{
echo 'You did the fuckup :(';
}
?>

输入字段的名称和ID必须相同喜欢这个

<input type="text" name="submitQuery" id="submitQuery" autofocus="autofocus" value="<?= $_GET['q']; ?>" placeholder="enter one movie"/> 
<input type="text" name="submitQuery2" id="submitQuery2" value="<?= $_GET['q2']; ?>" placeholder="and then another one"/>

未验证其中一个搜索字段
