Can't replace value with string.

Love2c0de · November 5, 2013

Good afternoon all,

I'm trying to setup a website and having a problem loading in dynamic content.

I have a main index.php file loading in template files - some which need to be dynamic.

I have a value within my template Home file called <__CONTENT__> and I'm trying to replace that with some images which have been retrieved from a database. It does replace the value with my output, but my homepage still displays the <__CONTENT__> value.

Here is my main index.php file:

<?php
session_start();
require("core/setup.php");
 
 
 
?>
<!DOCTYPE>
<html lang="en">
<head>
<title>Gardenable | <?php print($title); ?></title>
<link rel="stylesheet" href="css/font.css" />
<link rel="stylesheet" href="css/main.css" />
<link rel="stylesheet" href="css/respond" />
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
</head>
 
<body>
 
<div id="container">
<div id="header">
<img src="images/logo.png" alt="Gardenable - Making gardening accessible to everyone" id="logo" />
 
<div id="top_mid">
<p>Already registered? <a href="#">Login</a></p>
<p>Need an account? <a href="#">Register</a></p>
</div>
 
<ul id="navigation">
<li><a href="?page=Home">home</a></li>
<li><a href="?page=Products">products</a></li>
<li><a href="?page=Services">services</a></li>
<li><a href="?page=About">about</a></li>
<li><a href="?page=Contact">get in touch</a></li>
</ul>
</div>
 
<?php if(isset($left_column)){ print($left_column); } ?>
 
<div id="main_content"> 
<?php if(isset($content)){ include($filepath); } ?> 
 
</div>
 
<hr class="hidden_rule" />
</div>
 
</body>
</html>

This loads setup.php first:

function getDynamic($path,$page)
{
$path = substr_replace($path, "", strrpos($path, "/"));
$path .= "/queries/";
 
switch($page)
{
case 'Home':
$planters = require($path."getproducts.php");
return $planters;
break;
 
case 'Products':
 
break;
 
}
 
}
 
if(!isset($_GET['page']))
{
header("Location: ?page=Home");
die();
}
 
$_GET['page'] = "Home";
 
$page = $_GET['page'];
 
$path = $_SERVER['DOCUMENT_ROOT'] . "clients/Garden/core/content";
 
$pathinfo = pathinfo($path, PATHINFO_FILENAME);
 
$filepath = $path . "/" . $_GET['page'] . ".htm";
 
if(file_exists($filepath))
{
$planters = getDynamic($path,$page);
$content = file_get_contents($filepath);
var_dump($planters);
var_dump($content);
$content = str_replace("<__CONTENT__>", $planters, $content);
}
else
{
header("Location: ?page=Home");
die();
}

Here is my getproducts.php file:

<?php
 
// $dir = substr_replace($_SERVER['SCRIPT_FILENAME'], "", strrpos($_SERVER['SCRIPT_FILENAME'], "/") + 1);
 
$conn = new mysqli("localhost","root","","gardenable") or die("Error creating connection.");
 
$stmt = $conn->prepare("SELECT * FROM planter_images WHERE productID=? LIMIT 10");
 
//rand = 1,1 because not all images are in db yet, the only ID present is 1. <----modify once table complete.
$stmt->bind_param("i",rand(1,1));
$stmt->execute();
$stmt->bind_result($i_id, $p_id, $i_name, $p_price, $p_dims, $p_ref, $p_desc);
$stmt->store_result();
 
$row = $stmt->num_rows;
 
if($row)
{
$headings = array("Raised Planters","Rounded Planters");
$hcount = 0;
 
//image counter.
$x = 1;
 
$planters = "<div id='home_product_main'>";
$planters .= "<h3>".$headings[$hcount]."</h3>";
 
while($stmt->fetch())
{
$num = substr($i_name, strpos($i_name, "{$x}"), 1);
 
$planters .= "<div class='product_holder'>";
$planters .= "<a href='#'>";
$planters .= "<img src='core/content/planter_imgs/{$i_name}' class='home_prods' alt='Image not loading? Contact the administrator at admin@gardenable.co.uk' />";
$planters .= "</a>";
$planters .= "</div>";
 
if($num === "5")
{ 
$planters .= "<hr class='separator' />";
$planters .= "<h3>".$headings[++$hcount]."</h3>";
 
//reset image counter.
$x = 1;
}
else
{
$x++;
}
}
 
$planters .= "</div>";
}
 
return $planters;
 
mysqli_close($conn);
?>

Here is my Home.htm file:

<p>Gardenable is a garden product and services company based in Clacton on Sea in Essex. We specialize in designing and creating bespoke garden products and also provide local garden services such as decking, jet washing and hedge trimming.</p>
 
<h3>Featured Products</h3>
 
<__CONTENT__>

I've attached an image.

As you can see from the var_dump() the replacement has been performed and I later echo the $content variable out AFTER it has been changed.

Any ideas?

Thank you for your time.

Kind regards,

<?php if(isset($content)){ include($filepath); } ?>

You replaced the string in $content, but you're including $filepath, the unchanged HTM file.

Try:

<?php if(isset($content)){ echo $content; } ?>

Thank you very much. It was $content before but I was using include() instead of printing.

Thanks a lot!

Kind regards,
