Why functions.php doesnt work, blank page after reload - php

after adding this to functions.php, i get an error (white page), i have the open tag php and a closing.
<?php
add_theme_support('menus');
function my-theme_add_scripts() {
wp_enqueue_script( 'google-map', 'https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false', array(), '3', true );
wp_enqueue_script( 'google-map-init', get_template_directory_uri() . '/js/google-maps.js', array('google-map', 'jquery'), '0.1', true );
}
add_action( 'wp_enqueue_scripts', 'my-theme_add_scripts' );
?>

try function my_theme_add_scripts() instead of function my-theme_add_scripts(). You can't use - in your function names.

How to run script for specific page from child-theme?

I'm working on a project that I have a child-theme on which I'm running specific functions from the function.php file.
My problem is that when I try to add an if condition to only run the script on a specific page, it doesn't work.
I'm using the functions.php from the child theme.
In other words... I need to be able to get the current page on the child theme.
What am I doing wrong?
add_action(
'init', function() {
if (is_page('contact')) {
wp_register_script( 'my-func', get_stylesheet_directory_uri() . 'my-func.js', '', '', false );
wp_enqueue_script( 'my-func' );
}
}
);
Thanks
for theme code will go to your functions.php file and for plugin code will go to the public functions.
add_action( 'wp_enqueue_scripts', 'my_assets' );
function my_assets()
{
if (is_page('booking')) {
/* for plugin */
wp_enqueue_style($this->plugin_name, plugin_dir_url(__FILE__) . 'css/custom.css', array(), $this->version, 'all');
/*for theme */
wp_enqueue_script( 'script-name', get_template_directory_uri() . '/js/example.js', array(), '1.0.0', true );
}
}

How to get access to jquery in wordpress?

In my theme header.php i added:
<?php wp_enqueue_script("jquery"); ?>
And try to use jquery in functions.php:
function remove_xprofile_links() {
remove_filter( 'bp_get_the_profile_field_value', 'xprofile_filter_link_profile_data', 9, 2 );
global $current_user;
get_currentuserinfo();
$user_id = $current_user->ID;
$field = xprofile_get_field_data(3, $user_id);
if($field="Покупатель")
{
?>
<script type="text/javascript">
jQuery(document).ready(function( $ ){
$("#nickname,#display_name").parent().parent().hide();
});
</script>
<?php
}
}
add_action( 'bp_init', 'remove_xprofile_links' );
But in console still ReferenceError: jQuery is not defined
How to use jquery correctly?
Probably you added the wp_enqueue_script line in your header.php after the wp_head() function has already been executed, but that's not the real issue.
The problem is that you shouldn't enqueue your scripts in header.php, but in your theme's functions.php file, adding an action to the wp_enqueue_scripts hook, like explained in this example:
/**
* Proper way to enqueue scripts and styles
*/
function theme_name_scripts() {
wp_enqueue_style( 'style-name', get_stylesheet_uri() );
wp_enqueue_script( 'script-name', get_template_directory_uri() . '/js/example.js', array(), '1.0.0', true );
}
add_action( 'wp_enqueue_scripts', 'theme_name_scripts' );
In your case this should be enough:
add_action( 'wp_enqueue_scripts', function() {
wp_enqueue_script('jquery');
} );

Link to an external javascript file with WordPress

Excuse me, I'm very new to PHP and WordPress, but I'm trying to link to an exterenal js file called trans.js, that relies on jQuery. Here is the code at the beginning of the header.php:
<script type="text/javascript" src="<?php bloginfo('template_url'); ?>/js/trans.js"></script>
and here is the enqueue within the functions.php
function twentytwelve_scripts_styles() {
global $wp_styles;
wp_enqueue_style( 'twentytwelve-style', get_stylesheet_uri() );
}
add_action( 'wp_enqueue_scripts', 'twentytwelve_scripts_styles' );
function my_scripts_method() {
wp_enqueue_script(
'custom-script',
get_stylesheet_directory_uri() . '/js/trans.js',
array( 'jquery' )
);
}
add_action( 'wp_enqueue_scripts', 'my_scripts_method' );
Yet it still does not link up with the trans.js — does anyone know why this is?
add_action( 'wp_enqueue_scripts', 'my_scripts_method' );
function my_scripts_method() {
wp_register_script( 'my-first-script', get_stylesheet_directory_uri() . '/js/trans.js', );
wp_enqueue_script( 'my-first-script' );
}
Try this, i guess you dint register the script.

Wordpress get_page() and plugin shortcode not working

I have a query to get a post in wordpress:
<?php
$page_content = get_page(2);
echo do_shortcode($page_content->post_content);
?>
The page that is being loaded has a shortcode in it that loads a slider. The slider markup is loading but the javascript and css files required for the plugin are not showing up in the source code. How can I fix this?
you did not supply any relative source code or link, but did you load the JS and css ?
Is the slider comes from a plugin ? is it your plugin ? is the plugin activated for said page ? did you enqueue your styles and scripts ??
Anyhow, as a first measure , try to load it manually on the page
function my_scripts_enq()
{
// Register the script for a plugin:
wp_register_script( 'custom-script', plugins_url( '/js/custom-script.js', __FILE__ ) );
// or
// Register the script for a theme:
wp_register_script( 'custom-script', get_template_directory_uri() . '/js/custom-script.js' );
// then enqueue the script:
wp_enqueue_script( 'custom-script' );
}
add_action( 'wp_enqueue_scripts', 'my_scripts_enq' );
For fast debug you can can simply try :
if( is_page(42) ){
add_action( 'wp_enqueue_scripts', 'my_scripts_enq' );
}
for styles you should do :
function load_styles()
{
// Register the style for a plugin:
wp_register_style( 'custom-style', plugins_url( '/css/custom-style.css', __FILE__ ), array(), '20120208', 'all' );
// or
// Register the style for a theme:
wp_register_style( 'custom-style', get_template_directory_uri() . '/css/custom-style.css', array(), 'se16205117', 'all' );
// then enqueue the style:
wp_enqueue_style( 'custom-style' );
}
add_action( 'wp_enqueue_scripts', 'load_styles' );
BTW - as a side note , From codex
$page_id = 2;
$page_data = get_page( $page_id );
// You must pass in a variable to the get_page function. If you pass
in a value (e.g. get_page ( 123 ); ), WordPress will generate an
error. By default, this will return an object.

how do i use wp_enqueue_script?

OK, so this is in my functions.php file: (the following is the edited version to utilize cool's answer below. I'm leaving the original afterward:
function mdg_setup_scripts() {
wp_register_script( 'hoverIntent', get_bloginfo('template_url').'/js-custom/hoverIntent.js', array( 'jquery' ));
wp_enqueue_script( 'hoverIntent' );
wp_register_script( 'mdMenuAnimation', get_bloginfo('template_url').'/js-custom/mdMenuAnimation.js', array( 'jquery' ));
wp_enqueue_script( 'mdMenuAnimation' );
}
add_action( 'wp_enqueue_scripts', 'mdg_setup_scripts' );
Here's what I originally had:
function mdg_setup_scripts() {
wp_register_script( 'hoverIntent',
get_bloginfo( 'template_url' ) . '/js/hoverIntent.js',
array( 'jquery' ),
false,
true );
wp_register_script( 'mdMenuAnimation',
get_bloginfo('template_url') . '/js/mdMenuAnimation.js',
array( 'jquery', 'hoverIntent' ),
false,
false );
if (!is_admin()) {
wp_enqueue_script( 'mdMenuAnimation' );
}
}
add_action( 'init', 'mdg_setup_scripts' );
The js files are present in the indicated folder.
But no JavaScript at all is loading on the front end.
I'm doing something wrong, but what?
Do I need to register jquery (I thought WP had jquery in it, though)?
Do I need to separate the enqueue call? Do I need to add something to my header.php?
You dont need to add jquery. If it is not added, and if your custom script depends on it (like you wrote in code) it will be added by wordpress.
This code will work (i just tested it) but..
Instead of this:
if (!is_admin()) {
wp_enqueue_script( 'mdMenuAnimation' );
}
wordpress recomed that you use hooks:
Wordpress-codex: Use the wp_enqueue_scripts action to call this function, or admin_enqueue_scripts to call it on the admin side.
So it should be something like this:
function my_scripts_method() {
wp_register_script( 'somehover', get_bloginfo('template_url').'/js-custom/hoverIntent.js', array( 'jquery' ));
wp_enqueue_script( 'somehover' );
}
add_action('wp_enqueue_scripts', 'my_scripts_method');
Wordpress-codex: by using the wp_enqueue_scripts hook (instead of the init hook which many articles reference), we avoid registering the alternate jQuery on admin pages, which will cause post editing (amongst other things) to break after upgrades often.
