I am having trouble getting wp_enqueue functions to work. I've looked at all the documentation on it but am having trouble sifting through and finding out what is supposed to go where.
so far I understand that I am supposed to register and enqueue the files from the functions.php file of the theme I am creating. So that is exactly what I do. I create some PHP tags and drop it in the middle of them, at the bottom of the page. Save and Upload.
When I reload, it just returns a blank white screen, must be an error in the code or something.
Here is the function:
<?php
function add_scripts(){
wp_register_script('jquery', 'http://code.jquery.com/jquery-1.5.2.min.js');
wp_register_script('nivo', get_bloginfo('url').'/scripts/nivo.js');
wp_register_script('slimbox',get_bloginfo('url').'/scripts/slimbox2.js');
wp_register_script('picasa', get_bloginfo('url').'/scripts/jquery.EmbedPicasaGallery.js');
wp_register_script('pwi',get_bloginfo('url').'/jquery.pwi-min.js');
wp_register_script('swf', get_bloginfo('url').'/jquery.swfobject.1-1-1.min.js');
wp_register_script('simpletube',get_bloginfo('url').'/scripts/jquery.simpletube.js');
wp_register_script('jqvalidate', get_bloginfo('url').'/jquery.jqvalidate.js');
wp_enqueue_script('jquery');
wp_enqueue_script('nivo');
wp_enqueue_script('slimbox');
wp_enqueue_script('picasa');
wp_enqueue_script('pwi')
wp_enqueue_script('swf');
wp_enqueue_script('simpletube')
wp_enqueue_script('jqvalidate');
}
add_action('init','add_scripts');
?>
So is there some sort of problem with my syntax? I'm not that strong with PHP.
Any help is greatly appreciated. Thanks!
It's kind of hard to debug it without seeing the whole file but the fact you get a 'blank page' suggests there's definitely something larger than a syntax problem somewhere.
Do you definitely have correctly nested php tags? i.e.
<?php
some code
<?php
some more code
?>
some more code
?>
will give you problems.
Also, it's now common practice to leave the last ?> from the end of the file (it means you wont have any issues with having whitespace after the closing tags and they're not necessary)
On top of that, you've used wp_register_script('jquery'...) - WordPress already has jquery registered. If you wish to re-register it, you need to wp_deregister_script('jquery') first. I'd also only do that outside of the admin, so:
if(!is_admin()){wp_deregister_script('jquery'); <your wp_register_script stuff> }
If these things don't help, copy and paste your entire functions.php file (use pastebin.com and give us a link)
As an aside, you're using get_bloginfo('url') several times - which means you're running lots of unnecessary calls to the database. Stick it into a variable and save yourself a little overhead:
$my_url = get_bloginfo('wpurl');
wp_register_script('thing', $my_url.'/script/location/file.js');
Oh! One more thing, I don't think url is an allowed argument for get_bloginfo() I think you want wpurl
Codex page on get_bloginfo() function
Good luck!
Missing ; for the following two lines:
wp_enqueue_script('pwi')
wp_enqueue_script('simpletube')
Instead of your code I would use:
<?php
function add_scripts(){
wp_enqueue_script('jquery', 'http://code.jquery.com/jquery-1.5.2.min.js');
wp_enqueue_script('nivo', get_bloginfo('url').'/scripts/nivo.js');
wp_enqueue_script('slimbox',get_bloginfo('url').'/scripts/slimbox2.js');
wp_enqueue_script('picasa', get_bloginfo('url').'/scripts/jquery.EmbedPicasaGallery.js');
wp_enqueue_script('pwi',get_bloginfo('url').'/jquery.pwi-min.js');
wp_enqueue_script('swf', get_bloginfo('url').'/jquery.swfobject.1-1-1.min.js');
wp_enqueue_script('simpletube',get_bloginfo('url').'/scripts/jquery.simpletube.js');
wp_enqueue_script('jqvalidate', get_bloginfo('url').'/jquery.jqvalidate.js');
}
add_action('wp_enqueue_scripts', 'add_scripts');
So please notice I have removed "wp_register_script" as using that is totally unnecessary if you are going to call wp_enqueue immediately after register.
wp_register_script
Is used so that you can afterwards call it ANYWHERE else in code without including the path.
Also big change is that I'm not calling the function from
init
But I'm calling it from
wp_enqueue_scripts
Also please consider adding additional parameters to your wp_enqueue_script such as
wp_enqueue_script( string $handle, string $src = '', array $deps = array(), string|bool|null $ver = false, bool $in_footer = false )

I am using the following code:
<p><?php esc_html_e( 'It looks like nothing was found at this location. Maybe try one of the navigation links above or a search? Or it is possible you are trying to access a restricted page without being logged in to gain access.', 'shapely' ); ?></p>
Which ends up being displayed as follows:
It looks like nothing was found at this location. Maybe try one of the navigation links above or a search? Or it is possible you are
trying to access a restricted page without being logged in to gain
access.
What I want to display is this:
It looks like nothing was found at this location.
Maybe try one of the navigation links above or a search?
Or it is possible you are trying to access a restricted page without
being logged in to gain access.
So what I want is a way to break the line. I tried <br /> and \n, and neither work. Is there a way to add line breaks in the esc_html_e() function?
I know this a older question, I wanted to to point out that there is no need to use the output buffering functions in PHP. You can simplify this code by calling the WordPress function esc_html__() instead of esc_html_e(). This function will return the escaped value instead of echoing it out.
https://developer.wordpress.org/reference/functions/esc_html__/
echo nl2br( esc_html__("Line1\nLine2\nLine3", 'shapely') );
First off you can't use \n inside single quotes. Also, line breaks won't be rendered as such on on a webpage. From the looks of things esc_html_e() actually echoes the output so to capture & process it you'd need to do something like this:
ob_start();
esc_html_e("Line1\nLine2\nLine3");
$output = ob_get_contents();
ob_end_clean();
echo nl2br($output);
But this seems like an awful lot to go through and probably the wrong way to go about it. If you need to output html you probably don't be using esc_html_e() to begin with. Really hard to say without more context.
To put my question into context, I'm working on an entirely static website where 'post' pages are created by myself manually - there's no CMS behind it. Each page will require a <pre> <code> block to display code as text in a styled block. This could be very few - several which is why I'm trying to do this for ease.
Here's what I've done -
function outputCode($code) {
return "<pre class='preBlock'><code class='codeBlock'>".htmlentities($code)."</code></pre>";
}
The code works as expected and produces an expected outcome when it's able to grab code. My idea is to somehow wrap the code for the code block with this function and echo it out for the effect, fewer lines and better readability.
As I'm literally just creating pages as they're needed, is there even a way to create the needed code blocks with such function to avoid having to manually repeat all the code for each code block? Cheers!
EDIT:
I was previously using this function and it was working great as I was pulling code from .txt documents in a directory and storing the code for code blocks in a variable with file_get_contents(). However, now, I'm trying to get the function to work by manually inputting the code into the function.
Well. Wrapping the function input in ' ' completely slipped my mind! It works just fine now!
If I understand correctly, you want to re-use your outputCode function in several different PHP files, corresponding to posts. If yes, you could put this 1 function in its own file, called outputcode.php for example, and then do
include "outputcode.php";
in every post/PHP file that needs to re-use this function. This will pull in the code, from the one common/shared file, for use in each post/PHP file that needs it. Or maybe I'm misreading your last paragraph :(
My PHP knowledge is very basic. I've built a child theme and the functions.php is all from bits and pieces found on the web. All works great at the moment, and I've reused it on another website. But in several places I had to manually input blog name, email address, etc. What I want is to make it reusable without any further interventions over it. I've covered all problems, but one: changing the default wordpress#example.com email.
// Changing default wordpress email settings
add_filter('wp_mail_from', 'new_mail_from');
function new_mail_from($old) {
return 'notifications#example.com';
}
This works, although to make it reusable without intervention I need to somehow retrieve the site's URL without http:// and www. I've made a test page and used:
$my_site = str_replace('www.','', $_SERVER['SERVER_NAME']);
echo 'notifications#'.$my_site;
It worked on the test.php file, but not in Wordpress' functions.php. The mail is sent and received, but the sender is 'notifications#' with nothing after #. I've used it as
return 'notifications#'.#my_site;
I've tried another approach:
$custom_email = 'notifications#'.str_replace('www.','', $_SERVER['SERVER_NAME']);
function new_mail_from($old) {
return $custom_email;
}
This one doesn't show any sender at all, it's from "unknown sender".
I've tried to work with site_url() instead of $_SERVER, but I haven't managed to make it work either. I didn't tried using home_url() because maybe in some cases home_url() will use a custom page (like a landing page).
Is there a way to solve this problem I have?
Thank you.
Ok, with a bit of help from a friend, I've found something that works:
function new_mail_from($old) {
$custom_email = 'notifications#'.str_replace('www.','', $_SERVER['SERVER_NAME']);
return $custom_email;
}
So basically all I need is to put $custom_email inside the function.
#MadBreaks Now... I know your advice was to avoid str_replace, but I didn't manage to understand parse_url and how to use it. Why isn't str_replace a good choice?
#Victory $_SERVER['SERVER_NAME'] and $_SERVER['HTTP_HOST'] did for me the same thing. Could you please tell me what's the difference? Or pros and cons in using each of them in this situation? Thank you.
I am getting a strange 500 Internal Server Error with a new script I am trying to implement in the actual site. Here's a screen:
![500 Internal][1]
I can route to this files manually without problems and they are working too. But not in the script itself. The Paths are also correct.
Heres the link to the Site:
[>>> Link <<<][2] (just enter R10369 in the input field or a random number)
Everything else is working correctly except these 3 files:
reseller.php,
checkresellerid.php,
resellermail.php
I googled a bit and everywhere is the .htaccess mentioned. but I never modified it or overwrited it. What could be the Problem? Thanks for any Help and sorry for my bad Englisch.
(Let me know if you want to see the php files)
EDIT: I managed to include my new php files into wordpress but i still got the 500 Error
I checked out the website.
I think Wordpress doesn't let you call .php inside of it's system.
I mean you cannot call PHP files for ajax.
You need to use wordpress ajax. Here is a snippet how to use ajax:
Function.php in your theme file.
function myajax()
{
//do stuff
die();
}
add_action( 'wp_ajax_nopriv_product_s', 'myajax' );
add_action( 'wp_ajax_product_s', 'myajax' );
And in your javascript file using jQuery:
The url may change, maybe it's enough to have wp-admin/admin.ajax.php or something like this, i don't really remember right now.
$.post('/wp-admin/admin-ajax.php',{action:'myajax',yourdata:"mydata"}).done(function(data)
{
//do stuffs
});
Update:
So basically if you want to have ajax request inside wordpresss, you need to define these things and use it like this. the "action" parameter is the function name which you want to call. And you need to put the PHP code into your current theme's function.php.
I am reading the No frills magento layout book written by Alan Storm. I have come across the following code:
public function handleAction()
{
$this ->loadLayout();
$handles = Mage::getSingleton('core/layout')->getUpdate()->getHandles();
var_dump($handles);
exit;
}
What is the need of that exit in this code ? That code works perfectly without that exit.
It stops the rest of the code from executing, looking at that script it seems like the purpose of it is to debug something. Having the rest of your page render won't make that debugging any easier since CSS styles will be applied that could make the var_dump() less readable.
Also there could be a redirect involved or such which could cause your var_dump() to disappear immediately, using exit you prevent the redirect from happening.
Bottom line, it's just not needed to have the rest of the code render.
