I am trying to create a body class name based on a specific page in php. What I need to do is first define a variable and then check if the variable exists, and then if it exists display that one, otherwise if it is something else, then do something else, or if nothing then do not show any.
<body<?php if (defined('PAGE_KEY') && var == "homepage") echo " class=\"homepage\"";
elseif (defined('PAGE_KEY') && var == "page3") echo " class=\"page3\"";
elseif (defined('PAGE_KEY') && var == "page12") echo " class=\"page12\""; ?>>
This code will be located in my head.php.
My thought was to first check if variable was defined and if so then check what the variable was defined as and then based on that variable it will display a respective class.
The goal is for example on the page12 for the body tag to look like this:
<body class="page12">
But for example for the body tag on page55 (which I don't want to show a class for) to look like this:
<body>
In doing so I am able to now define css specifically for a page within the header where the body tag happens to be located.
Problem is first I don't know how to define the variable in the page, and second I don't know exactly how to write the php code above properly.
Attempt, for example on page12 I would have this code:
<?php PAGE_KEY = "page12" ?>
This code would be for example located in page12.php.
Also keep in mind, that the variable will come AFTER the body tag.
I also thought of trying to see what the page URL is but I think that's just making things too complicated.
Based on #Jordi's suggestion, how about this:
<body class="<?php echo PAGE_KEY ?>">
on head.php.
And then on page12.php, this:
<?php PAGE_KEY = "page12" ?>
and for example on page5.php this:
<?php PAGE_KEY = "page5" ?>
so that on those respective pages the body tag shows this:
on page5.php:
<body class="page5">
and on page12.php the body tag will show this:
<body class="page12">
Is this right?
#Jose made this suggestion, is this correct?
for example, on page12.php, to define the variable as 'page12', this:
<?php define("PAGE_KEY", "page12"); ?>
Is that what you were suggesting to do?
Ok! This problem is solved. I just needed to add in the code in the individual pages before the head.php include so I could define it. Thanks for your help! :)
You can use and define a constant like this :
<?php
define( "PAGE_KEY","homepage" );
?>
.
.
.
<body<?php echo " class=\"" . constant( "PAGE_KEY" ) . "\""; ?>>
For another page :
<?php
define( "PAGE_KEY","page5" );
?>
.
.
.
<body<?php echo " class=\"" . constant( "PAGE_KEY" ) . "\""; ?>>
You only change the constant, the rest is the same for every page.
Edit #1:
<body
<?php
define( "PAGE_KEY","homepage" );
echo " class=\"" . constant( "PAGE_KEY" ) . "\"";
?>
>
Edit #2:
<?php
define( "PAGE_KEY","homepage" );
?>
.
.
.
<?php
include( "head.php" >
?>
Now, head.php is something like this :
echo "<body class=\"" . constant( "PAGE_KEY" ) . "\">";
Start with something like this.
<?php
//each page and its class. Many pages can share the same class. If a page doesn't
//have a class, don't include it.
$classes = [
'homepage'=>'home_class',
'page1'=>'base_class',
'page2'=>'home_class',
'page3'=>'special_class'
];
//Adjust this from one page to the next
$this_page = 'homepage';
//get the class corresponding to current page, or '' if no class
$this_class = isset($classes[$this_page])? $classes[$this_page] : '';
?>
//insert the class for this page.
<body class="<?=$this_class ?>">
You can improve on it by moving the $classes array to another file (eg a config file) and including it in all your pages. This way you don't have to rewrite the array on every page (a bad idea because difficult to make a change, easy to make a mistake)

this is my second question here, first one was resolved quite quickly and I appreciate any help I get. Here's the thing:
I have a folder views in which I have a folder named _global in which I have my beforeContent.php and afterContent.php those are my header and footer of actual Web pages. The main content in my pages is set in other view folders and I have no problem there.
I have this script in my beforeContent.php (this one shows my navbar):
<?php if (Session::exists('user_id')): ?>
<?php include 'app/views/_global/menu-session.php'; ?>
<?php else: ?>
<?php include 'app/views/_global/menu-no-session.php'; ?>
<?php endif; ?>
basically, if a user is logged in, it will show menu-session.php, if there's no user logged in, it will show menu-no-session.php.
my menu-session has this in it:
<ul>
<li><a <?php if ($FoundRoute['Controller'] == 'Main') echo
'class="active";'?> href="<?php echo Configuration::BASE_URL; ?>">Home</a>
</li>
<li><a <?php if ($FoundRoute['Controller'] == 'Overview') echo
'class="active";'?> href="<?php echo Configuration::BASE_URL; ?
>overview">Overview</a></li>
</ul>
it has more tabs, but you get the point.
I had to use this function that chooses the controller that will decide if the page is active or not. basically: If i'm on a page Overview, the script asks if the active Controller is named 'Overview' and if it is, it will select the tab as class="active".
However, this is wrong: my teacher said I can't have scripts in my view files (it's not wrong, it's just bad practice) and I need another method of doing this:
So, I created a method class Misc.php with a function Misc::url:
public static function url($link, $text){
echo '<a href="' . Configuration::BASE_URL . $link . '">' . $text .
'</a>';
}
this way my menu-session can just be:
<ul>
<li>Misc::url('', 'Home')</li>
<li>Misc::url('overview', 'Overview')</li>
</ul>
Now: I need a correct function in Misc.php where I have the >>> $FoundRoute['Controller'] <<< if statement implanted, something like:
Misc::urlWithActive($link, $text){
if ($foundRoute['Controller] = *thiscontroller*) {
echo '<a href="' . Configuration::BASE_URL . $link . '">' . $text .
'</a>';
}
I actually don't know how to write that.
I Really hope you guys understand what I need to do here and help me.
I'm a little lost here, hoping that someone can help. I'm using the Meta Box plugin for WordPress, and I'm trying to create a process for the user to select an option from a predefined list, and then assign a URL to that option as a link. Im trying to define the URL in a variable, and then call it in a function, but I'm still a little green on PHP syntax. this is my code now:
<?php
$article_url= rwmb_meta('orion_2016_article_url', 'type=URL');
if (rwmb_meta('orion_2016_article_source') != '') {
echo '<a href= ("$article_url") target=blank>';
echo rwmb_meta('orion_2016_article_source');
echo '</a>';} ?> on <?php the_date(); ?>
Since the options are already predefined, it seems like assigning a random URL to one of the options should be pretty simple. Hopefully this makes sense!
You need to to place variables you wish to echo inside double quotes or simply concatenate strings using . as in my example. Note that I didn't check the plugin's specific syntax, only general PHP syntax.
<?php
$article_url= rwmb_meta( 'orion_2016_article_url', 'type=URL' );
if (rwmb_meta('orion_2016_article_source') != '') {
echo '' . rwmb_meta( 'orion_2016_article_source' ); . '';
} ?> on <?php the_date(); ?>
Still learning php as I go so this might just be something I haven't gotten to yet but it's the next roadblock in building my personal site. I have a basic understanding of includes such as linking:
<a href="art.php?id=image id&name=This is my title&menu=side-menu-portfolio">
to pull my includes but I've come to a small problem in that my generic art-gallery page needs to switch between a 'portfolio' header and an 'artwork' header. So I figured I could either build "art-gallery.php" AND "port-gallery.php" and go back and relink everything or just make it so that when you call the link like the above code I just specify which header goes with it. Unfortunately this would also require going back and changing every link. But I noticed that I did state:
...&menu=side-menu-portfolio...
and the pages are already calling side-menu-artwork or side-menu-portfolio so if I could just call in menu and cast aside the 'side-menu-" portion then it would just use artwork or portfolio and call the right header. Unfortunately this is where my limited knowledge of php and syntax come in. I have tried to produce the following code based on my php and js understanding:
<?php include("headlines/headline-" . $_GET[menu - "side-menu-" ] . ".php"); ?>
but I don't know if my syntax is just wrong or if what I'm trying to do is impossible to begin with. Note that when I try this I get
Function Include error of "Warning: include(headlines/headline-.php)"
so it looks like everything else is reading correctly, I just don't know if or how I can extract the word I want from the rest of the menu name.
Should be, Assumed your included file name is headline-side-menu-portfolio.php
<?php
$filename = str_replace("side-menu-", "", $_GET['menu']); // headline-portfolio
include("headlines/headline-" . $filename . ".php"); // headline-portfolio.php
?>
Something like this :
<?php include("headlines/headline-" . $_GET["menu"].".php"); ?>
<!--gives include("headlines/headline-side-menu-portfolio.php")-->
where
$_GET["menu"] = 'side-menu-portfolio'
Try this:
<?php include("headlines/headline-" . $_GET['menu'] . ".php"); ?>
Your code is wrong.
Instead of
<?php include("headlines/headline-" . $_GET[menu - "side-menu-" ] . ".php"); ?>
try
<?php include("headlines/headline-" . $_GET['menu'] . ".php"); ?>
You should check if the file exists before you try including it.
if (file_exists($filesrc)) { ... }
Better yet don't let the user change the menu through a $_GET variable. Instead link to a specific page or pass a variable then decide what menu to get. Like
switch ($_GET['menu']) {
case 'side-menu':
include("headlines/headline-side-menu.php");
break;
}
Just use
$_GET['menu']
, the "side-menu-" part is already in the content of your variable passed as param.
You propably want to do an if .... else so to include one header or another based on the $_GET variable menu.
So something like this will do this:
if($_GET['menu'] == 'side-menu-portfolio') {
include 'headliens/side-menu-portfolio.php';
} elseif($_GET['menu'] == 'side-menu-other') {
include 'headliens/side-menu-other.php';
}
okay....your are almost there....just quotes missing from include syntax...it should be
include("headlines/headline-.php"); /* notice the quotes*/
so it should be
<?php include("headlines/headline-" .$_GET['menu'].".php"); ?>
where $_GET['menu'] should be in the url, like:
art.php?id=image id&name=This-is-my-title&menu=side-menu-portfolio
so what's happening her ??
Upon execution of the line :
<?php include("headlines/headline-" .$_GET['menu'].".php"); ?>
$_GET is fetched from the url and replaced in the header tag, so now the header tag becomes :
<?php include("headlines/headline-"."side-menu-portfolio".".php"); ?> => <?php include("headlines/headline-side-menu-portfolio.php"); ?>
Also. may i suggest that for :
<a href="art.php?id=image id&name=This is my title&menu=side-menu-portfolio">
don't use space in the url, either replace it by - or _
This is the code I am working with:
echo '' . $post_type->labels->singular_name . '' .$markup;
It currently links correctly but shows the entire http string before the link.
Example: http://www.blah.com/blah/blahPortfolio. When it should be just "Portfolio".
Fresh eyes on this would be so helpful.
There are two errors that I can see:
<?php bloginfo('template_directory'); ?> If you are using echo it means <?php tag is already open so use only bloginfo('template_directory')
There are two closing tag for a tag (i.e. />) You use only one (i.e. >)
So the code will be like this:
echo '' . $post_type->labels->singular_name . '';
Try this code chunk and let me know --
echo '' . $post_type->labels->singular_name . '';
This may be a simple one for you PHP experts out there. I need to give a certain <h1> to a post else show the page/post title.
I have this so far, it works if it is on a single post page, but when I am on a different page it just shows 'the_title' instead of the page title. I think its basically about calling a php function inside an already open php tag, if that makes sense. Here is the code:
<?php
if ( is_single() ) {
echo 'News';
} else {
echo the_title();
}
?>
The Wordpress tag for the page title is <?php the_title ?>
You are echoing 'the_title' as a string, you need to actually execute the function like so:
if ( is_single() ) {
echo '<h1>News</h1>';
} else {
echo '<h1>' . the_title() . '</h1>';
}
Note the closing quote to halt the string, and the . to concatenate the WordPress function the_title(), and then another to join the ending <h1> tag.
A cleaner way is to add the tags inside the function itself, like this:
<?php the_title('<h1>', '</h1>'); ?>
No need for 'echo'.
