未定义的索引年份|未定义的变量年份 [英] Undefined index year | undefined variable year

问题描述

你好我不断得到这么多错误，说明未定义的变量和索引在我已经初始化的地方。我不知道错误在哪里说的是真正的错误。



我尝试过：

<？php $ actual_link = basename（$ _ SERVER ['PHP_SELF']）;？> 
<？php 
 if（isset（$ _ GET ['id']））
 {
 $ oinkid =oink =。$ _ GET ['id']; 
} 
其他
 {
 $ oinkid =; 
} 
？> 
< style> 
 #oink：悬停{
背景：无; 
} 
 
＃oink1 {
 background：none; 
 border：0px; 
颜色：白色; 
} 
< / style> 
< div class =header_btm1> 
< div class =wrap> 
< div class =header_sub1> 
< div class =h_menu1> 
< ul style =display：block> 
< li>< a id =oink1>图表：< / a>< / li> 
< li 
<？php 
  $ theyear = $ _GET ['year']; 
 echo $ theyear;  
 if（ $ typetype  ==hits）
 {
 echo'class =active' ; 
} 
？> 
>< a href =analytics.php？type = hits& year =<？php echo $ theyear。$ hello;？>> Hits< / a>< / li> 
< li 
<？php 
 if（ $ typetype  ==dl）
 {
 echo'class =活性'; 
}

<？php

}

<？php 
 // $ query = mysql_query（SELECT DISTINCT YEAR（treg）as $ theyear FROM count ORDER BY treg）; 
 $ query = mysql_query（SELECT DISTINCT YEAR（treg）FROM count）; 
 if（mysql_num_rows（$ query）> 0）{
 while（$ row = mysql_fetch_assoc（$ query））
 {
 $ myyear = $ row ['YEAR（treg） ）']; 
 echo< li; 
 if（$ theyear == $ myyear）

解决方案

actual_link = basename（

_SERVER [ 'PHP_SELF']）;？>
<？php
if（isset（

_GET ['id']））
{

Hello i keeps getting this lots of error saying undefined variable and indexes where in i already been initialized it. i don't know where the error been said is the real error or not.

What I have tried:

<?php $actual_link = basename($_SERVER['PHP_SELF']);?>
<?php
if(isset($_GET['id']))
	{
	$oinkid = "oink=".$_GET['id'];
	}
else
	{
	$oinkid = "";
	}
?>
<style>
#oink:hover{
background: none;
}

#oink1{
background: none;
border: 0px;
color: white;
}
</style>
<div class="header_btm1">
<div class="wrap">
	<div class="header_sub1">
		<div class="h_menu1">
			<ul style="display: block">
				<li><a id="oink1">Chart: </a></li>
				<li 
				<?php
				$theyear = $_GET['year'];
				echo $theyear;
				if($typetype == "hits")
					{
				echo 'class="active"';
					}
				?>
				><a href="analytics.php?type=hits&year=<?php echo $theyear.$hello; ?>">Hits</a></li>
				<li
				<?php
				if($typetype == "dl")
					{
				echo 'class="active"';
					}
				?>
				><a href="analytics.php?type=dl&year=<?php echo $theyear.$hello; ?>">Downloads</a></li>
				<li
				<?php
				if($typetype == "read")
					{
				echo 'class="active"';
					}
				?>
				><a href="analytics.php?type=read&year=<?php echo $theyear.$hello; ?>">Read</a></li>
				</ul>
				<ul style="display: block">
				<li><a id="oink1">Years: </a></li>
				<?php
					//$query = mysql_query("SELECT DISTINCT YEAR(treg) as $theyear FROM count ORDER BY treg");
					$query = mysql_query("SELECT DISTINCT YEAR(treg) FROM count");
					if (mysql_num_rows($query) > 0) {
						while($row = mysql_fetch_assoc($query))
						{
							$myyear = $row['YEAR(treg)'];
							echo "<li";
							if($theyear == $myyear)
								{
									echo " class='active'";
								}
					<pre>

echo">$myyear";

}
}
?>

解决方案

actual_link = basename(

_SERVER['PHP_SELF']);?> <?php if(isset(

_GET['id'])) {
