Hello!
I ran into a problem today while pushing the local version of my portfolio site to my host and well, it doesn’t work. The most significant error has to do with a function I made which returns page content dynamically, utilizing the HTTP Header query, and fetching local files dynamically depending on logical checks.
I had to troubleshoot a bit to find where the problem seems to be localized, which is at a point I’m looping through the returned json results key via a foreach loop. The error states that I’m passing an invalid argument. Through further searching I was able to determine this was likely due to the json data returned is null. So though i’m getting an error in the loop, it’s actually with getting that JSON content, because all I was ever able to get were NULL values at that point of contact.
How It Works
Suposing url contains: www.michaelgoldspinner.com/$page=about, and with index calling Page function content():
The function will check if the page is a main page, if so it’ll match the value of page set in HTTP Header through switch statement for each page, if it matches a page it’ll use the make_page function. This function takes a path to the file which passes it along to a file getting function depending on the file type detected. The page loads php file just fine as the function fetching them uses an include, however for json files it seems to only return null values.
##The Code
The following code & information describe the situation
URL: www.michaelgoldspinner.com/$page=about
HTML: index.php (Page class assigned to $thePage)
<!-- Content -->
<!-- Nested under html>body>main -->
<div class="page__content">
<?php if ($thePage->isMain() || isset($_GET["post"])) : ?>
<?php $thePage->content(); ?>
<?php else: ?>
<p>Sorry. . . Page failed to load.</p>
<?php endif; ?>
</div>
PHP: Functions.php (Contains the Page Class which operates on index under all circumstances)
class Page {
// Logicals: Manage situational checks
// ----------------------------------------
public $title = array (
"sample"=> array("sample", "Sample"),
"blog"=> array("blog", "Blog"),
"work"=> array("work", "Portfolio"),
"about"=> array("about", "About")
);
function isMain() {
// Page isMain if only page key detected; or neither is.
if ( isset($_GET['page']) && !isset($_GET['post']) || !$_GET['page'] && !$_GET['post'] ) {
return true;
} else {
return false;
};
}
// Handlers: Manage data requests
// ----------------------------------------
function get_file($path) {
include $path;
}
function get_json($path) {
// How to use file_get_contents with include path: file_get_contents('./path/to/file')
$value = json_decode(file_get_contents($path, true), true);
return $value;
}
// Constructors: Manage data display
// --------------------------------------------
function make_body($jsonContent) {
$value = $jsonContent;
foreach ($value["content"] as $key) { //Echo Content Array
echo $key;
}
}
function make_page($pathParam="content/page/", $fileParam="page_welcome.html", $titleParam="title", $subParam="date") {
// Is Json File?
$isJson = strpos($fileParam, ".json") ? TRUE : FALSE ;
// Grab Content
$value = $isJson ? $this->get_json($pathParam.$fileParam) : $this->get_file($pathParam.$fileParam);
// Header
$header = $isJson ? $this->make_header($value[$titleParam], $value[$subParam]) : NULL;
// Body
$body = $isJson ? $this->make_body($value) : $value;
}
// Operators: Deliver content to index & perform operations from page condition
// -----------------------------------------------------------------------------
function content() {
// If Main
if ($this->isMain()) {
// Build Page
// Check Page Type
switch ($_GET['page']) {
case $this->title["blog"][0] :
$isFilterOn = isset($_GET["filter"]) ? TRUE : FALSE;
if ($isFilterOn) {
switch ($_GET['filter']) {
case 'recent':
$this->make_page( 'content/posts/', 'static_PostItem_web.php');
break;
default:
break;
}
} else {
echo '<section><h2>Error</h2><p>Filter is off...</p></section>';
break;
}
break;
case $this->title["work"][0] :
$this->make_page('content/page/', 'page_work.json', null, null);
break;
case $this->title["about"][0] :
$this->make_page('content/page/', 'page_about.json', null, null);
break;
case 'sample':
$this->make_page('content/page/', 'page_sample.php', 'title', 'subTitle');
break;
case 'demo' :
$this->get_file('content/page/page_demo.php');
break;
default:
$this->make_page('content/page/', 'page_welcome.html', null, null);
break;
}
}
// If Not
else {
// Build Post
$this->make_page('content/posts/'.$_GET["filter"].'/', $_GET['post'].'.json', 'title', 'date');
}
}
}
If you follow the above links to the page (although they were used to suppose the situation) I have set up two sections, one showing an echo of file_get_contents, which returns the string from the file, and a var_dump of a json_decode being used on that file_get_contents result, with associate array option.
I’d really appreciate any input someone has. It must be a configuration issue?
