Trying to get property of non-object error with thumbnail
I'm trying to get the thumbnail of my featured image to display on my home.php (blog) page.
It is displaying fine, but when debugging mode is turned on, I get this error:
> Notice: Trying to get property of non-object in /Applications/MAMP/htdocs/wpflat/wp-content/themes/wpflat/content-blog.php on line 2
My code is
<a href="<?php the_permalink();?>"><?php echo get_the_post_thumbnail($page->id, 'thumbnail'); ?></a>
How do I solve this issue? | I believe from your error that you are using this code inside the loop. You should be using `the_post_thumbnail()`. The code you are using is used outside the loop.
**EDIT**
It is always good practice to always first check if you have a thumbnail to display
So you should use
<?php if(has_post_thumbnail()): ?>
<a href="<?php the_permalink();?>">
<?php the_post_thumbnail( 'thumbnail'); ?>
</a>

echo vs output variable
Someone once told me, that it is good for performance, not to open and close php tags and use echo all the time, like that:
<hgroup>
<h1><?php echo getHeading1(); ?></h1>
<h2><?php echo getHeading2(); ?></h2>
</hgroup>
Instead he uses an output variable and echoes it in the end.
$output .= '<hgroup>
<h1>' . getHeading1(); . '</h1>
<h2>' . getHeading2(); . '</h2>
</hgroup>';
echo $output;
Does that really make any difference? When do I use which method? | I believe this topic was addressed quite thoroughly here. I might add that within the WordPress community it is common syntax practice to default to echoing tags with an option or alternative/interior function to return the result instead. This I believe is driven by the level of code experience the average user within WordPress has and understanding a simple tag structure is "easier" than string concatenation of a php variable. The goal of extensibiltiy also drives this mentality by providing modular that can be "dropped" into a template in a similar vien of `add_action`. | stackexchange-wordpress | {

Order posts by category name
Is there any way to order posts by category name?
I tried
$args = array(
'post_type' => 'dlm_download',
'posts_per_page' => 10,
'paged' => $paged,
'order_by'=> 'cat',
'order' => 'ASC'
);
But it does not really work, could please someone give me a hint? | I had the same struggle like you, thank i sat down and rethought the whole thing, what you actually need to is select all the categories, and pass the category id to it.
Since you use a dlm_download you will need to do the following, get the terms from the dlm_download_category
$cats = get_terms('dlm_download_category');
Loop trough the category and pass `query_posts` in it
so
foreach ($cats as $cat)
{
$args = array(
'post_type' => 'dlm_download',
'dlm_download_category' => $cat->slug,
);
query_posts($args);
if (have_posts()) :
while (have_posts()) : the_post();
// your stuff here
endwhile;
endif;
}
And there you go
PS: if you want to make it with `posts` not with `custom post`
Than `$cats = get_categories();`
and pass `'cat'` in to the argument.
Hope its clear and helps. Cheers | stackexchange-wordpress | {

Permission functions within wordpress
I'm currently developing a website and am exploring all possible options to restrict file viewing. I'm trying to find a way where I can load php files like my theme-options.php and cpt.php without them been displayed in the admin panel even to admin users e.g appearance > editor.
I'm leaning towards the answer having more to do with file permissions then any actually functions calling specific files and then providing restricted access to all users.
1.How can I restrict access to these files yet load them at the same time?
Thanks | The simplest way to hide them from the editor is to put them at least two directories deep. The editor only traverses one directory down when displaying files for editing. | stackexchange-wordpress | {

How to optimize performance without transient?
I've built a widget to output some fancy content from an API. I realize today I added a transient system so everytime the widget is updated transient is deleted and everything is alright.
What I missed is that the generated content is actually different according URL. So my system is not appropriate, for now the content remains the same on each post.
How would you handle this? I think one transient per post is bad bad idea, isn't it?
I could delete the transient code but this increase page load. | I don't think a transient per post is a bad idea at all, and it's certainly more efficient than firing the API call on every load.

WP FullCalendar Image Thumbs on Full Calendar

Default Timezone setting in WordPress - is that global?
Despite the WordPress Options' Timezone setting for the whole WordPress installation, **is it necessary to declare the default timezone in all the date/time places in a WP theme/plugins?**
date_default_timezone_set('Asia/Dhaka');
echo date('d M Y - D - h:i A');
Suppose I'm handling with something where I'm checking whether the date&time is equals to **_TODAY_**. You know what "Today" means is a bit variable - variable to server time, variable to local time etc.
That's why I'm looking for a standard procedure to follow in WP projects, whether to set the default timezone each and every time (or do I call them always in the header?) or to avoid them as WordPress itself declared that already (just tune that before).
I'm just looking for a standard procedure - what to follow... | I think the safest way to handle it is to use the API to get the local time as set in WordPress settings-
$today = date( 'd M Y - D - h:i A', current_time( 'timestamp' ) );

Split Media Queries in different files!

Is it a good idea to split the different media queries in different files, check the width of the page in functions.php and then with an IF call the "correct" using `wp_register_style` and `wp_enqueue_style`? | There are no functions in wordpress that checks or determine screen sizes.

Your solution here is to do it old school, using media queries in your main stylesheet as done in all of the default themes shipped with wordpress.
Closing off, I would most probably think that if there was such functions to determine screen sizes in wordpress, that it would be completely overrated and useless and time wasting just to load something simple like a stylesheet | stackexchange-wordpress | {

Change the search results header from plugin

"if parent category is" conditional?
I searched through the codex but couldn't find anything helpful. I tried the code below but it didn't work. The default sidebar still shows up for all category pages.
<?php
$ep_category = get_the_category();
if ($ep_category->category_parent == 'watch-isatv') {
include ('sidebar-isatv.php');
}
else {
get_sidebar();
}
?> | Your solution won't work, because `$ep_category->category_parent` is ID (integer) and not slug (string). So this comparison doesn't make any sense... ;)
One way to do this would be this function (from Codex):

function post_is_in_descendant_category( $cats, $_post = null ) {
foreach ( (array) $cats as $cat ) {
// get_term_children() accepts integer ID only
$descendants = get_term_children( (int) $cat, 'category' );
if ( $descendants && in_category( $descendants, $_post ) )
return true;
}
return false;
}
}
After adding it to your theme, you can use it this way:

media library not showing thumbnails after deleting full image
I am using a bit of code, that deletes the unneccessary full images after uploading and adding different sizes.
deleting function in functions.php:
add_filter( 'wp_generate_attachment_metadata', 'delete_fullsize_image' );

So, that works great, but the problem is I can not see any thumbnails in the media library anymore as they are generated by the full size image only, it seems. This makes it really complicated/hard to work with the uploaded images.

Just let the full size images stay where they are. You don't have to use them. You'll probably find a situation where you want to use it anyways.
Also, I've never tried it, but you might be able to disable default image without deleting it by adding the following to your functions.php file:

How To Get Search Term and Use in Function
I'm trying to write a function that will 'grab' the search term entered into the blog search form, and then hook the function to the `get_search_query` filter like this `add_filter('get_search_query','myFunction');` so that everytime a search is made, 'myFunction' runs and grabs the search term (or so I think), I have this line in myFunction to grab the search term
`$search_term = get_search_query();`
but it seems to be causing problem, the blog doesn't display, except I comment that particular line out. What is the right way to achieve the subject. Thanks.
Here is the code:
function myFunction(){
global $wpdb;
$search_term = get_search_query();
$table = $wpdb->prefix . "tableName";
$insert = "INSERT into $table(`serach_term`) VALUES ('$search_term')";
$wpdb->query($insert);

The search query is passed to the filter as an argument, so you don't need to fetch it-
function myFunction($search_term){
// now you can use $search_term directly in your code

That being the case, what you need is `get_object_taxonomies()`
$taxonomies = get_object_taxonomies( 'post', 'objects' );
That will not give you the terms in the taxonomies. You will need to loop over `$taxonomies` and pull the terms out, if that is what you are trying to do. For example:
$taxonomies = get_object_taxonomies( 'post', 'objects' );

Shortcode / WP_Query in post changes context
We have a shortcode that causes WP_Query to be executed, retrieving an instance of a custom post type. In our single.php this changes the context (after the call to the_content()) from the original post (with the shortcode in it) to that of the custom post retrieved.
I spotted this because the comments template wasn't displaying, as the comment_status on the custom post is 'closed' - what we're interested in, however, is that the comment_status on the original post is 'open'.
Is this an error in the execution of our shortcode/custom post type, is there a way of doing this that won't mess up what happens in single.php?

How can I manually upgrade translations?

Unfortunately, WP's automatic upgrade features are not compatible with the server this site is installed on, so I have to do it manually.
What bothers me is that I still have a red "1" on the Dashboard menu, telling me there's an update available. When I consult the details, everything is empty, except for the "Translations" section, at the bottom of the page.
How do I upgrade these manually? As I said, I can't just let WP do it automatically because it doesn't work.

Child Theme > Template
I incorrectly updated the Template variable in the style sheet of a Child theme. However, the site was still OK. The only indication I had was in the Admin section it said this theme did not exist.
So, my question is - is this variable actually used when rendering a page or is it just a hint for the control panel to notify the user? | That "Template" line... this one...
Template: twentyfourteen
... is a required field for child themes. That is what tells WordPress that this is a child and not a stand-alone theme, and also which theme to use as a parent. Files not replaced by the child theme are loaded from the parent.
Without that "Template" line you are bound to have problems but how many problems you have depends (I am speculating) on how much the child depends on the parent. If the child replaces only one or two parent files you may have a lot of trouble. If the child replaces nearly everything, you may not notice the problem. And of course a lot depends on which files are replaced and which should load from the parent.

Restrict custom post type from appearing with ?post_types=
When appending the querystring post_types = "name of your post type", it displays all the posts. I am using a plugin that has its own custom post type which is restricted (only users that have purchased a membership can view it).. but today while messing around with searching, i discovered that post_types querystring. Is there a way to prevent this private custom type from showing up? are there other similar "magic" querystring in wordpress? | `register_post_type()` has quite a few related arguments, of which `publicly_queryable` controls precisely what you are describing.
However note that it will _completely_ kill the CPT on front end — individual posts, archives, even post previews.

Why is get_the_excerpt returning full content
I have my home page set to a static page with a custom page template. Here I want to show posts, but just the excerpts with a "Read more" link. I want to use the more tag, which is a part of wordpress so I hate the fact that this doesn't work! If I simplify the code that would be it:
while ( $q->have_posts() ) : $q->the_post();
$the_exc = get_the_excerpt();
echo $the_exc;
endwhile;
So how do I convince wordpress that on my home page I just want to show the excerpts (until the more tag). And this is like 75th time I'm dealing with this the_excerpt, the_content, issue. How do you guys do this? | Based on this...
> ... I just want to show the excerpts (until the more tag).
... it sounds like what you want is to show the post content up to the `<!--more-->` tag, rather than the excerpt proper which is hand-written into a special field. To do that, you need to use `the_content()`/`get_the_content()` rather than the `excerpt` cousin functions, and you need to have the `global` variable `$more` set correctly, but that is not hard to do.
$q = new WP_Query(array('post_type'=>'post'));
global $more;
while ( $q->have_posts() ) {
$q->the_post();
$more = 0;
$the_exc = get_the_content();
echo $the_exc;
}

4th Network Site Database Errors?
4th site created but not available in the admin menu or the my sites screen.

The My Sites menu at the top also only shows 3, not the 4th.
If I click to My Sites>Network Admin>Sites then I see all 4 listed on this page wp-admin/network/sites.php and can acces the fourth site.
Why doesn't it show up in all the other menus? Can you help me find the root cause of the problem and fix it?
I had previously tried to delete the site, and then re-created the site, but the issue remains. I also turned off all plugins, but the issue remains. I'm afraid that there is a deeper problem which is perhaps database related. Can you help me solve it please? | Yeah, that was the problem. The site was configured with incorrect admin user information. The problem was solved by going to the user profiles and setting myself as a "super administrator" of the 4th site. Some how it had been created under a different user which was full of incorrect information. To make the site show up in your menu just go to "my sites" > "Sites" and you should see a list of all the sites.

Is there a real benefit in using wordpress optimized hosting?
I'm building a site for a client. This site often takes a long time to load initially, but is rather fast when loading the next page because of WP Super Cache plugin.
But still, the majority of people visiting a site for the first time will navigate away if the site doesn't load completely in < 3 seconds. So I'm having a bit of a problem here.
We are considering a new hoster. The budget is limited, so we prefer the (starter package) hosting of www.neostrada.nl, but they have a shared server, and it is not wordpress optimized.
**Is there a real benefit in using Wordpress optimized hosting likewww.bluehost.com/wordpress? Or are there any other things that can make a Wordpress site load faster on the first visit?** | It depends on what you need.
The software environment is the same you need for every other PHP site where you want to get an efficient workflow:
* up-to-date PHP (currently 5.5, so you can use Opcache) with at least 128 MB memory limit
* the same for MySQL
* web server with a rewrite engine
* regular backups
* SSH
* Git
You can get that everywhere for 5 €/month. In fact, I have seen more expensive “WP optimized” hostings where you could not even get PHP 5.4. Not acceptable, newer PHP versions are _much_ faster.
What does make a difference is the support: If you need a lot of support and there are people who know WordPress very well, this will be very beneficial. Good, fast support is worth some money. | stackexchange-wordpress | {

Featured image with link to post shortcode, image displaying above the post
I have created a shortcode to display the featured image linking to the post:
function ck13_post_image($atts){
extract(shortcode_atts(array(
'ck_img_size' => 'full'
), $atts));
$show_the_image .= '<a href="' . get_permalink() . '">' . the_post_thumbnail("$ck_img_size") . '</a>';

}
//---------------------------------------------
function register_shortcodes(){
add_shortcode('show-post-img', 'ck13_post_image');
}
add_action( 'init', 'register_shortcodes');
But instead of displaying the image inside the post, the image is displayed above it.
The weird thing is that the link to the post is displayed correctly inside the post, just the image is above.
Did i make some mistake? How can i make this work? | `the_post_thumbnail` echoes its value, which doesn't work in variable assignment. Use `get_the_post_thumbnail` instead.
Most WordPress API functions follow this pattern, there are typically two versions - one which will `echo` the result and another with `get_` prepended which will `return` the result. | stackexchange-wordpress | {

Capability to prevent upload of files
I need the ability to allow users to insert media (images) into a page / post, but not allow them to upload the files.
The only capability I can see is 'upload_files', which allows a user to upload / insert files.
Is there a way to prevent upload of files but still show the media manager (via the 'Insert Media' button on the Edit screen) allowing users to insert the images?
My thought of how to approach this would be via jQuery - run a script when the capability is something like 'my_insert_media', which would hide the 'Upload' tab of the media uploader. Of course this could be worked around by disabling Javascript in the browser, but that's not a major concern for this project.
Any other suggestions, or holes in this approach?
Thanks, Dan | You can try with this:
function remove_media_tabs($strings) {
unset($strings["insertFromUrlTitle"]);
unset($strings["setFeaturedImageTitle"]);
unset($strings["createGalleryTitle"]);
unset($strings["uploadFilesTitle"]);
return $strings;
}
add_filter('media_view_strings','remove_media_tabs');
This will remove 'Upload file' and 'Insert from URL' links when you open insert media screen, so user will be able only to select images or whatever that is already in media library.
For more things you can do with unset, check in: wp-includes/media.php file. | stackexchange-wordpress | {

Is there a way to run upgrade.php for one blog?
I just ran the auto update to verion 3.9 today, but am having problems with the "Network Update".
I seem to have a firewall or network problem with this error :

Anyways, is there a way to run the database updates per blog ? Can I use a special URL ? Can I do it from shell command line ?
On an old forum post, someone suggested that update.php runs automatically the first time you log into your blog admin ( even if Network Update hasn't been run ). I wonder if that's true.
Thanks | WP CLI has a command that can upgrade the database:
wp core update-db

wp core update-db --site="

Custom post type navigation on static page
I'm using the following code on a WP3.9 site to show a bunch of custom post types with pagination on a static page set as the frontpage:
$args = array(
'post_type' => 'movie'
);
$paged = (get_query_var('page')) ? get_query_var('page') : 1;
$wp_query = new WP_Query( array_merge( $args, array('paged' => $paged) ) );

function disable_redirect_canonical( $redirect_url ) {
$redirect_url = false;
return $redirect_url;
}
add_filter('redirect_canonical','disable_redirect_canonical');
Then I can go to **/page/3/ and greater** , but **/page/2/** still redirects to the main page.
I'm really lost about this and I'm not really sure where to look to fix this problem.

Ajax Call in page theme not working?

<script type="text/javascript">
function loadTweets() {$.getJSON(" function (json) {alert(json);});} setInterval(loadTweets(), 60000);
</script>
For some reason when i go to the URL in my browser, I get an Error 500. Same with my ajax call? How would i fix this?
I was told maybe a .htaccess file, but i dont think that would be an issue. For some reason this page is blocked. | 1. You shouldn't be including jQuery explicitly. WP ships with a copy and multiple copies tend to mess things up. See `wp_enqueue_script()`.
2. You shouldn't be trying to load PHP file inside a theme directly. It won't load WordPress environment that way (unless it tries to do so explicitly, which is usually very fragile and pretty much cannot be reliably done in public code).
3. Error 500 is unfortunately very not transparent thing. It is produced by your web server rather than WordPress and there is no insight into what might be causing it that can be gained on WP level. You'll have to look up details for error in your web server logs / ask hosting support to do that. | stackexchange-wordpress | {

Difference between is_user_logged_in and $_session['uname']
I am writing a condition to check if a user is logged in, not sure which of the below condition to use :
if(!is_user_logged_in()){
And
if(!isset($_SESSION['uname'])){
Basically need to check if any user is logged in. | The Core function for checking whether a user is logged in is `is_user_logged_in()`. You should use that if at all possible.
WordPress does not use sessions at all, by default, and never has so far as I can remember. When I try `var_dump($_SESSION);` I get an "Undefined variable" Notice exactly as I expected. I haven't explicitly tested with the latest release but I doubt it introduced such a radical change.
If your site uses sessions, it is not the Core doing it. There must be a plugin involved. If that plugin uses sessions as a part of a custom login system you may have to use `$_SESSION['uname']` but hopefully your plugin is written such that `is_user_logged_in()`, which is pluggable, works correctly with the custom login system. | stackexchange-wordpress | {

Hide plugin dashboard menu item for specific roles

Anyone any ideas? | I think is a better strategy, that you add on the activation a new capability and add this capability to the Administrator role.

add_action( 'admin_init', 'fb_add_capabilities' );
function fb_add_capabilities() {
`$GLOBALS['wp_roles']->add_cap( 'administrator', '_your_custom_cap' );`
}
### Check for Cap
Inside your source can you check for this capabilty:
if ( ! current_user_can( '_debug_objects' ) )
return;
### Remove Cap
On the deactivation (Hook `register_deactivation_hook`) and uninstall (Hook `register_uninstall_hook`) of the plugin is it necessary, that you remove the cap. `remove_cap()`

Bootstrap with Flexslider jQuery Issue

User-uploaded images without an account

Conditional tag is_page with a custom post type
Accordingly to the is_page documentation, supplying the slug as an argument WP can tell me whether the current page is the one represented by the slug. Perhaps I am using the wrong slug?

Please find below a code snippet to let you understand:
'rewrite' => array( 'slug' => 'faqs/archivio' )
);
register_post_type( 'faqs', $args );
I did this a go using the slug used for a custom post type, but I wasn't able to get this working.
So two questions?
1. Is the is_page supposed to work in this case?
2. if not, what the best alternative?
Thanks Andrea | The creation of a custom post type have it inside the definition, a post type. Also is page only a default post type. If you register your custom post type, then check for this post type, not for a page.
### Conditional Tag `is_singular`
The function, conditional tag `is_singular()` main purpose is to check if viewing a singular post. However, it can also be used to check if viewing a singular post of a given post type by entering the `$post_type` parameter as shown in the following code snippet.
`is_singular( 'your_custom_post_type' );`
or different post types
`is_singular( array( 'your_custom_post_type_1', 'your_custom_post_type_2' ) );`

I use the plugin Debug Objects to debug topics in this context. Maybe this helps you also, often easier as read the code or codex.

is_single(); Question
If a page would contain this code:
`<?php if( !is_single('') ): ?><div id="navtoggle"></div><?php endif; ?>`
But regardless of it would show the div navtoggle, would that mean the code makes WP think the page is a `posts` page?
If not, how can I make WP only show navtoggle on the homepage? | You should have a look at using conditional tags in wordpress. `is_single()` is the conditional tag for a single page, ie single.php.

Strategies for coping with hyperagressive spambots?
A couple of my sites are getting slammed by a hyperagressive distributed spambot. It's just pure link spam. It all comes from one user name, but from a variety of IPs.
Akismet is catching the spam, so my sites aren't defaced. But it's affecting performance.
What is best practice, if any, for mitigating this?
**Edit** There are about 400 of these in 24 hours. They're coming from a rotating bunch of IP addresses. There are between five and ten hits from each address.
* 60.173.9.*, 60.173.10.* and 60.173.11.*
* 112.123.168.*
Both of these address ranges are assigned, according to apnic.net, to ISPs in China.
(I'm guessing malware-infested cybercafes, but who knows?)
Again, is there a best practice to deal with this junk? Or just let akismet do it? | One surprisingly useful solution to foil most spam-bots is to use a honeypot. Put an extra entry field into your comment forms, and then hide it with css. Normal users won't fill it in because they won't ever even see it. Based on that, you can safely assume that anytime an entry is made with that field filled, that it's a bot and you can just discard/mark it as spam. | stackexchange-wordpress | {

Use the_content outside the loop

Injecting a javascript banner code right before & after wordpress navigation menu
I am trying to develop a plugin to inject a javascript banner code right before and after the wordpress navigation menu but I am unable to find any solution to this problem. Does anyone have any idea?
I cannot append to a Div ID either since every wordpress theme uses different div id and class for navigation menu.

You could create a custom Walker that could include those hooks but it is going to be a theme problem, either way.
If that is not satisfactory, you will need to alter the DOM with Javascript. I don't know if that is even possible/viable for the code you want to include but if that is an option you need to hook code to `wp_enqueue_scripts` something like this: <

TwentyThirteen - Footer overlapping content
So, I'm designing a theme for a friend of mine, but there is a problem with the footer.
Assuming the very bottom of the browser window is 1000px, it seems that the page content ends at 1000px, and the footer sits between 900px - 1000px.
Thusly, the last 100px of content are cut off, and unreadable.
How can I move the bottom of the content to end at 900px, leaving room for the footer?
See here: <
Note the submit comment button is cut off.

I'm no expert by any means, and I hope what I've said makes sense. | This is because your footer is fixed which removes it from the normal page flow. You can add 50px padding-bottom to your #main div (or `.site-main` on line 790 of your style.css).

WordPress can't prevent you from adding PHP files to the root directory, but there is no builtin functionality to load those files. You can load them yourself but if you are not careful they will load outside of WordPress context, which is a painful way to work.

Performance disadvantge of second installation instead multisite feature?
Is there any (performance-)disadvantage when I run two installations of wordpress instead of using the multisite feature?
My question refers only to the difference of multisite / two installations. I'm aware of that there will be more load etc.
### Some explanations (when necessary)
I run a private blog on a vhost.
I want to run a different wordpress instance on the same host.
Both sites are completely independent of each other - means different themes, plugins etc.
The private blog is a single-user. The new site could have many users and will move onto a single vhost when it will be successful enough. | I have never benchmarked this but...
Since every HTTP request is a distinct request, the whole WordPress Core will load on every request either way, and a little bit more code loads for Multisite. So, it seems to me that two installs should run slightly better than a single multisite install, though I doubt you will actually notice the difference. | stackexchange-wordpress | {

How to print the output of the get_num_queries function from frontend to backend?
I'm trying to develop a simple plugin and figure out how to display the number of queries executed in frontend, to an admin page (plugin options page), using get_num_queries() function.
I've added the following code to my plugin's function file and works well showing (in my footer) the number of queries processed to create the frontend page:
function get_queries() {
$get_queries ='';
$get_queries .= get_num_queries();
$get_queries .= ' queries';
echo $get_queries;
}
add_action('wp_footer', 'get_queries', 999);
If I use `echo get_queries();` in the place where I want to display the value in my plugin page, it display the number of queries processed in the plugin options page, not from frontend.
My question is: how to print the number of queries processed to create the frontend page in my plugin options page? | Each HTTP request is a new one so you will need to save the data to the database. You can't just "pass" the data from the front to the back end.
function get_queries_wpse_143544() {

update_option('page_queries',$dbq);
}
add_action('wp_footer', 'get_queries_wpse_143544', 999);

}

(*thanks to @s_ha_dum for the function)

Thank you! | With that code in place, all you should need to do is poke the page with `wp_remote_get()` as your backend page loads, and before you need to retrieve the option value. By doing this, you avoid the possibility that no visiter has visited the page. Your request will be that visitor.

is it good to use Wordpress in the same url extension in terms of seo?
i have got a website and i want to add a Wordpress blog to it for additional (fresh) content and of course, better SEO. i'm new to Wordpress but i found out that the pages created by it are stored in the database so it's almost impossible to link to any of those pages, so it's confusing for me because i don't know that when Google crawls my domain will it also crawl database-stored wordpress pages and if it does, is this any good for SEO ranking of my whole site?
i just wanna know using the wordpress blog like "www.website.com/en/blog" will have the same SEO impact as making a blog using Dreamweaver, which has separate HTML pages that can be linked to. (apart from marking-up content)
Thanks | It is true that WordPress stores your page/post content in a database. Every CMS does this, however. Googlebot crawls links so it will see the public or front-end version of the page that WordPress produces at each URL. WordPress will serve up the page content from the database along with the theme/template/css rules in effect on that page.
Bottom line: how you see the final output of your WordPress pages is how Google will crawl them, essentially. Googlebot is not using a browser, for example so it interprets your page differently.
Name your posts with good, descriptive titles and personally I would recommend using the "post name" style for Permalinks. This gives you good keyword-rich URLs.

Use default value of wp_customizer in theme_mod output?
Is there a way to output the default value of a `wp_customize` text field type using the `echo get_theme_mod ();` without actually going in the Theme Customizer, modifying something and then saving it?
I just read on another stackexchange question that the `get_theme_mod` will only show something after you save it in Theme Customizer. Not being able to output the default value of a `wp_customize` setting seems to defy the purpose of using a default value.
So, back to the question: is there a way to automatically display the default value of a `wp_customize` setting in front-end? | Sadly not - all your customize controls are hooked onto `customize_register`, so they'll only ever come into play when customising the theme for the first time.
`get_theme_mod()` takes a second argument for a "default" value - yes, it means two instances of data in your code, but it's a half-solution.
I guess a more DRY approach would be a coupling of globals & helper functions:
$my_theme_defaults = array(
'foo' => 'bar',
'baz' => 'boo',
);
function my_theme_customize( $wp_customize ) {
global $my_theme_defaults;

array(
'default' => $my_theme_defaults['foo'],

Different customer login form than administrator login form?
I've recently installed Woocommerce. I have realized that the administrator can access the back-end through the same login form presented to the customers. This, to me, presents a huge security risk.
I thought of a couple of solutions, but I do not know the code that would help me implement them:
* How can I prevent the administrators from logging in through the customer login page? (if statement on login from the customer login form that would check the role of the user and prevent login if the user is an admin)
* How can I present a login form so that only the customers can login through? (use a default or native login form set only for customers) | Although users have access to go to /wp-admin/, they will not have access to do anything on there. There is no security risk involved to being able to have access /wp-admin/ for WooCommerce users.
If you'd like however, you can setup an Apache protected directory with a password to /wp-admin/ that requires an additional user and pass to get to that URL. | stackexchange-wordpress | {
