Get variable not echoing

PHP
1

if folks, i m creating a page for some expermintal purpose and i m trying to echo value of url clicked but it isn’t echoing. i tried the mysql_error() in if statement but that too doesn’t show up. what am i missing?


if(isset($_GET['page'])){
    $sel_page = $_GET['page'];
        if(!isset($_GET['page'])){
            echo mysql_error();
        }
}else{
    $sel_page = $_GET['page'] = "";    
}

here is the link


echo "<a href=\\"content.php?page =" . urlencode($row["id"]). "\\"><li>{$row["menu_name"]}</a></li>"

and here is the get echo


echo "$sel_page";

now it says page not found, here is the full page code


<?php require("includes/functions.php"); ?>
<?php
if(isset($_GET['page'])){
    echo $_GET['page'];
}else{
    echo "Page not found";
}
?>
<body>

<div class="container">
  <div class="sidebar1">
  <?php 
  $con = mysql_connect("localhost","root","");
  confirm($con);
  $seldb = mysql_select_db("sandbox");
 confirm($seldb);
 //$query = "select * from subjects";
//$subject_set = mysql_query($query);
 $parent = get_subjects($subject);
?>
<ul>
    
<?php 
 while($subjects=mysql_fetch_array($parent))
 {
         echo "<a href=\\"\\"><li>{$subjects["menu_name"]}</a></li>";
            
            $pageResult = get_pages($subjects["id"]);
            echo "<ul class=\\"nested\\">";
            while($row = mysql_fetch_array($pageResult)){
                echo "<a href=\\"content.php?page =" . urlencode($row["id"]). "\\"><li>{$row["menu_name"]}</a></li>";
            }
            echo "</ul>";
 }
  ?>
</ul>  
    </div>
  <div class="content">
  <h1>Here</h1>
    <?php
        echo ($sel_page);
        ?>
    <!-- end .content --></div>
  <!-- end .container --></div>

what am i missing?

I figured out the reason i had space between page and =. But to my knowledge white spaces aren’t significant. then the error?

I am not seeing the whole code so I don’t why/where mysql_error() would come into play. Anyway I think you want this:


if( isset($_GET['page']) ) {
	echo $_GET['page'];
} else {
	echo 'Page not set';
}
