wordpress category conditional on attachment page - wordpress

How do I check the category on the image.php theme file in Wordpress?
I tried in_category('categoryname') but it did not work.
I want to use it outside of the loop. (Btw, the function also did not work inside of the loop...)
I need this to show banners according to the categories of the post.
I guess the problem is that the attachment is not associated with the category of the post?

Try in_category("foo", $post->post_parent)

how to customize post meta in wordpress?

currently my theme on WordPress is Neve , and my posts all over the blog shows the following meta info :
https://i.stack.imgur.com/ynu71.jpg
where :
1- post title
2- post author
3- post date
4- post category
i want to replace these post meta with similar to this:
https://i.stack.imgur.com/Xywa9.jpg
for this purpose i have created a child theme and then installed snippet plugin to add php code easily and deactivate it once it is not working . unfortunately i could not find the code that can do the required modifications on that post meta :
https://i.stack.imgur.com/uwCrS.jpg
can any one provide a full php code to modify all these changes in one time after pasting into snippet ? or if there is another way i can do it ?
You'll have to create a child theme (already done) where you can override the current blog post template, instead of using a snippet plugin. To do this, copy the blog post template file from your theme and add it to your child theme.
WordPress will now read your child theme template instead of your theme's template, and you can easily modify the DOM from there, and shape the layout/text however way you want. (You can use the theme editor built-in in WordPress to modify the new child theme file. No plugin required.)
This is the proper way to modify a post page without plugins, and you can easily grab thing such as a post date, author, etc. via WordPress' built-in function. Example of how to get the author name of a WordPress post in PHP.
As for, 'latest edition' date, I will lend you a snippet I wrote for a client as WordPress. This will return the date at which a post has been modified as long as it is different from the publishing date (tweaks are common right after publication so it's a tad pointless to show a "last edited date" as the same as the publication date).
function current_post_last_edited_date_formatted() {
if(get_the_modified_date() !== get_the_date()) {
return '<p class="last-edited"> Last edited <span class="data">'.current_post_last_edited_date().'</span></p>';
} else {
return '';
};
}
The function you see called in the condition are WordPress core functions. =)

Using Jetpack Portfolio Project in WordPress child theme does not call archive custom template

I have a child theme that uses the new Jetpack Portfolio Project custom post type and wish to modify archive.php to display custom results.
I'm using: WordPress v3.9.2; Theme: Child of Point, Jetpack is installed with Custom Content Types enabled, and Portfolio Projects selected in the Settings. (No other plugins that implement portfolio functionality are installed.)
According to the Codex:
Template Files
In the same way single posts and their archives can be displayed using
the single.php and archive.php template files, respectively,
single posts of a custom post type will use single-{post_type}.php
and their archives will use archive-{post_type}.php
and if you don't have this post type archive page you can pass BLOG_URL?post_type={post_type}
where {post_type} is the $post_type argument of the
register_post_type() function.
My understanding is that if you create files called single-jetpack-portfolio.php and archive-jetpack-portfolio.php within the child theme, WordPress will automatically use those files in place of single.php and archive.php respectively.
However, my child theme successfully calls single-jetpack-portfolio.php, but completely ignores archive-jetpack-portfolio.php, instead calling archive.php in the child.
I am stuck for a solution.
From the codex above, adding to the URL "?post_type=jetpack-portfolio" does cause the child theme to correctly use archive-jetpack-portfolio.php, but should I need to be manually modifying every single URL to explicitly specify this? Should WordPress not automatically be detecting this, as it does for the single-jetpack-portfolio.php file? How can I solve this?
I have tried:
Resetting the permalinks in case it was related to that (changing the option in Settings and saving and back again)
Adding an archive.php file to the child in addition to archive-jetpack-portfolio.php (I initially didn't have an archive.php in the child, so it used the parent's archive.php)
Publishing a new Jetpack portfolio project and updating an existing page (I read somewhere that publishing something might trigger Wordpress to see the changes)
Thanks in advance for any help.
I had the same problem described by the OP. When I visited mydomain.com/portfolio it would use the custom archive template. When I tried to view a project type it defaulted to the regular archive.php. I'm wondering if OP was viewing a project type page without realizing it.
My solution was to create a taxonomy template file. After playing around with it I figured out that
taxonomy.php
taxonomy-jetpack-portfolio-type.php
taxonomy-jetpack-portfolio-type-{name-of-project-type}.php
all worked correctly, depending on how specific you wanted to get.
There's more info at the wordpress codex: http://codex.wordpress.org/Template_Hierarchy#Custom_Taxonomies_display
Hope this helps someone.
I will be working on this the next days.
You should try this in the child archive.php first lines:
<?php
if( is_post_type_archive('jetpack-portfolio') )
get_template_part('content', 'jetpack-portfolio');
elseif( is_tax('jetpack-portfolio-type') || is_tax('jetpack-portfolio-tag') )
get_template_part('archive', 'jetpack-portfolio');
else continue;
?>

Dropdown of existing posts in a metabox

I want to have ability to choose for each page what post should appear in a sidebar, from multiple posts type. So I understand that I need a meta box with a dropdown list of all posts, but I don't know how to build this in functions.
I only found this solution which is quite similar to what I want, but this doesn't help me to much, because I can only choose from a single post type and display only in post pages.
There is a free plugin that will solve all of your woes. It's called ACF or Advanced Custom Fields. It has the ability to add a list of posts to a field and attach that field to pages. Here's how you'd do it:
First install the plugin and navigate to the custom fields screen. Setup your field exactly like this:
Then in the options below that section you need to select these options:
That will tell ACF to put the field only on pages. After you have set that up you will get a little sidebar block like this:
You can then select each post for the page and it will return that object on the frontend. You do need to use a little code to get the frontend to spit out the posts you need. Here is the code to get a frontend option from ACF. Inside of the sidebar.php file you need to add this code:
global $post; // Get the global post object
$sidebar_posts = get_field('posts', $post->ID); // Get the field using the post ID
foreach($sidebar_posts as $sidebar_post){ // Loop through posts
echo $sidebar_post->post_title; // Echo the post title
}
This will simply loop through the posts you select and echo out the title. You can do more with this by adding some other Wordpress post functions using setup_postdata(). This will allow you to do things like the_title() and the_content().
Hope this helps!

How do I use different category template in wordpress?

I am using Twenty twelve theme in wordpress to make a project. To display various styles of pages I can choose custom page template page, but I have to use category instead of pages.
But how I make different category template and use them ? Thanks.
You can do it in almost exactly the same way as you would do with pages.
Just follow the Wordpress Template Hierarchy:
"category-slug.php"
"category-ID.php"
etc
http://codex.wordpress.org/Category_Templates
So, if you have a category with the name "cars", the name of template for that category should be "category-cars.php" :)
Edit: a few minutes too late :(
You can check category by id and use native function where it needed.
get_template_part( 'custom_category', 'category' );
Also You can try something from here Wordpress Codex

How do I create a custom WordPress page?

I want my WordPress blog to have a page called music. On that page I will query the DB for posts with the category music and then change around the look and feel of the posts. So I can't just put a link to /categories/music/ because I want to do custom work on the posts.
Should I put this code in a separate php file and link to it? I think I may lose access to all the nice WordPress API calls if I do that.
I was thinking about using a filter, but I am not sure which one to use. I was thinking something like the following except the_title has not been grabbed yet so I cannot check the title.
function show_music(){
if( is_page() && the_title('','',false) == 'music' ){
echo "got here";
}
}
add_filter('pre_get_posts', 'show_portfolio');
How would you go about this?
You need to put the below code in the file, and then put the file in the Theme folder. Then you can create a page using Wordpress pages and select a page template with the name you put in this comment:
/*
Template Name: Something Goes Here
*/
You need to create custom page within your theme. If you dont have idea how to create custme page or template page in WordPress theme then view my easy tutorial How to create template page in WordPress
