Not validating one of the search fields - php

Question

I want to check if either of my search fields are empty, and if they are i write out a failure message. For some reason the following code doesn't work when I try to submit empty values in both search fields, or leaving the q2 search field empty. It only writes out the failure message when I only insert a value into the first field. Hope you guys can help.
<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 :(';
}
?>

Answer 1

The name and id of your input fields must be same
Like this
<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"/>
