I am using this code in a views template to print user name in a field. The output is fine except it doesn't shows as a link, as its supposed to.
<?php print $row->users_name; ?>
How can i modify the code to show the output as a link? btw this was the comment in the template file which i cant decode.
Variables available:
$view: The view object
$field: The field handler object that can process the input
$row: The raw SQL result that can be used
$output: The processed output that will normally be used.
When fetching output from the $row, this construct should be used:
$data = $row->{$field->field_alias}
What does a dpr of $row->users_name show? Is it supposed to contain the correct HTML for a link?
If not then take a look at the l function - http://api.drupal.org/api/function/l
Like Martin says you should let us know where you want the link to point to.

I have such html
<h1 id="1"><i>2</i>sample contents</h1>
I know by using the following work to get only text perfectly without html
response.xpath('//*[#id="1"]/text()').get() # sample contents
response.xpath('//*[#id="1"]/text()').extract_first() # sample contents
but if I assign into a variable then want to get only the text without html after?
For example
header = response.xpath('//*[#id="1"]')
# the below will get text WITH html tags
header.get()
header.extract_first()
What I want is if i assigned to header and I want to get text only, how am I able to do that?
Thanks in advance for any suggestions and help.
EDIT:
By testing Moein's answer, somehow what I get in return is "\r\n \r\n " spacings instead
You can continue your XPath address by calling xpath on header variable:
header.xpath('./text()').get()
I'm using rvest to scrape from https://www.psychologytoday.com/ca/therapists/m5g ; in particular what I'm after is the data-myurl html attribute in the div tag with id="results-page" . If you view source you'll see there's only one div with id="results-page" . The data-myurl attribute looks like the main URL except with the addition of a string of numbers separated by a period and underscore, like so
<div id="results-page" data-myurl="https://www.psychologytoday.com/ca/therapists/m5g?sid=1510588046.3852_2969">
The numbers you see will likely be different. To try and extract it, I use the following code:
require(rvest)
fsa <- read_html('https://www.psychologytoday.com/ca/therapists/m5g')
fsa %>% html_node('div #results-page') %>% html_attr("data-myurl")
However, this returns only
[1] "https://www.psychologytoday.com/ca/therapists/m5g"
So everything after the original URL is missing. It doesn't seem like a JS thing since I don't see any script tags when I view source. Does anyone know what these numbers in the URL actually are and how to extract them? Thanks!
You can't do this with rvest.
The page you're trying to scrape is dynamically rendered after loading the initial page. The content itself is always the same, but the sid numbers change the ordering of the results after loading the page. The sid changes on every visit and page reload.
I suspect this was done to avoid a market bias when searching for a therapist.
If you really want the sid number, you need to use a tool that handles dynamic pages like casperjs.

Edit:
Alternatively, if it has to be done in R then you can use RSelenium. (https://cran.r-project.org/web/packages/RSelenium/)
The relevant starting point would be here:
https://cran.r-project.org/web/packages/RSelenium/vignettes/RSelenium-headless.html
In my custom page type, you can select an uploaded file. That's fine, but in my ascx transformation, i'm having a hard time getting the URL. The field is 'Process'.
Here's what i currently have.
<%# IfEmpty(Eval("Process"),"N/A","<a href=" + Eval("Process") +" target='blank' class='icon download'>Download</a>")%>
When rendered, the html is this:
Download
I'm missing something.
You can use either of the 2 methods below. Both have their downfalls though.
<a href="<%# GetFileUrl("Process", "Something") %>"Link here<a/> this will
Downfall with this is if there is no value in the "Process" field, it will return an invalid URL. So I tend to use something a little better (but not much)
Item to download
This will create a valid URL with some invalid properties to it. Meaning if there is no value in the Process field, it will return 00000000-0000-0000-0000-000000000000. If the NodeAlias field is empty, it will return "download". So again, not 100% fool-proof but it works well in most cases.
Update
Check out this link:
https://devnet.kentico.com/articles/options-for-file-fields-in-structured-data
I think the piece you need in here is in the "CMS.File page type" section:
This is the link to the picture
Check out transformation methods reference
You can use <%#GetImage(Eval("Process"))%>. This will return an Image tag. There are a couple other parameters for sizing if you want to use those.
See the "Transformation reference" link on your Trasnformation editor, it goes to all the available transformation methods you can use.
In it it shows:
This will generate an actual image tag. If however you want a link, it usually is
/getattachment/<%# Eval("TheImage")%>/ImageFileNameCanBeAnythingThough.jpg
example:
/getattachment/1936c69d-a28c-428a-90a7-09154918da0f/Christmas.jpg
I feel like there is a really simple solution to this problem. However, after trying to solve it for about 3 hours unsuccessfully, I humbly come to you.
The Basics:
A custom post type, " band ", has been created, and has several
custom fields (which were created through the Advanced Custom
Fields
plugin.)
The Question:
How would I get and display the contents (specifically custom field data) of a specific band entry (using its ID or title or slug) inside of a regular post? (see diagram below)
(source: thisnewband.com)
.
Methods to Trigger the Display of the Custom Post Type:
We have to provide the ID/title/slug so that it knows what band post's content to display
Shortcode (such as [band id="21"] ) (added inside post content)
Custom Field (custom field name band-id where you can input the ID of the band)
What I've Tried and Why It Didn't Work:
Shortcode
`[band id="21"] inserted in post editor field
Used WP_Query to query post with type=band and ID="21".
Code located in functions.php
Result: It would echo static text but would not display any post-specific content (Band Name, etc.). Also would not pull post-specific custom field data.
(also tried query_post with no luck)
Custom Field
Entered ID (21) into custom field on post editor page.
Coded it directly into the post template:
Used WP_Query and had the ID in the array pull from the custom field.
Result: Nothing good happened.
Where I Keep Running Into Trouble:
It's hard to pull the custom field data from the custom post type while inside an actual post
The Optimal Solution:
Whether it's by using a shortcode, custom field, or even a new widget, it would be easiest if one could:
Create a PHP template with the code for just how the single Band content is supposed to display. (Including the loop). Example name: band-block.php
Use get_template_part('band-block'); to echo this code (either in Post Template or Shortcode via functions.php)
Thanks for your help! Let me know if you'd like to see any of my code.
I knew you have found a solution for your problem, but for others i will give them an other solution:
You can query by ID, no problem. Look at these: http://www.advancedcustomfields.com/resources/field-types/relationship/
But you have to check in the custom field "return format" the box "Post IDs". Then it works perfectly well.
Sorry for my bad english ;)
Cheers
With some amazing help from Hobo, I was able to come up with a solution!
The main problem was with trying to query by 'ID'. No matter what we tried, it just never worked well. (It could be the way that the Advanced Custom Fields stored the ID field contents.)
What did work:
Created a custom field for the post page in which to put the Band (custom post type) post name/slug into. (Custom field was named post-band-name and created with the Advanced Custom Fields plugin.)
Placed the query code in the Post Template. (See code below)
Done.
The Solution Code
Add this loop after the normal loop...
<?php /* Display all the author's posts from the custom post type ('band') */ ?>
<?php
$authorid = get_the_author_meta( ID, $userID );
$args4=array('author'=>$authorid,'post_type'=>'band', 'numberposts'=> -1);
$cquery4=new WP_Query($args4);
if($cquery4->have_posts()):
while($cquery4->have_posts()):
$cquery4->the_post();
?>
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>">
<p><?php the_title();?></p>
</a>
<?
endwhile;
wp_reset_postdata();
endif;
?>
In Orchard i can see the menu is output in MenuItem.cshtml with the line DisplayChildren(model).
I would like to take this html output and run an xslt transform to change the structure.
How can i get the menu item as the html and store this in a local variable (as opposed to it being output directly to the stream)?
var html = DisplayChildren(model);
Yup, it's that simple. It will give you a IHtmlString, that you can ToString() if you need to. But xslt? 8|
