Looking through the Smarty debug console I discovered the variable {$u}, which contains the array video => "".
{$u} also contains photo, interview, etc. which is taken from the t1 table in the database. The database does have a url in the video column, but it is not being captured in {$u}. The problem right now is that I can't figure out where {$u} is populated.
What is the best way to find out where $u is populated?
If you can't debug your code line by line (with Zend or Xdebug), try to search your PHP code for ->assign('u', ->assign("u" or your Smarty templates for {$u=, {assign name="u", etc...
Unfortunatly there is no way to make Smarty tell you automatically where a varible was declared.

I want to access the data of the object that comes as a smarty variable according to the variable I have defined.
I'm actually expecting like {$page->page_meta->description} as I wrote below. But nothing happens. It doesn't give an error. What is the problem?
Ok now I understand what you mean.
{foreach $metas as $meta}
{$page->page_meta->{$meta}}
{/foreach}
PS next time do not insert screenshots like this but write code
So, this is about a content from a website which I want to get and put it in my Google Sheets, but I'm having difficulty understanding the class of the content.
target link: https://www.cnbc.com/quotes/?symbol=XAU=
This number is what I want to get from. Picture 1: The part which i want to scrape
And this is what the code looks like in inspector. Picture 2: The code shown in inspector
The target is inside a span attribute but the span attribute looks very difficult to me, so I tried to simplify it using this line of code here =IMPORTXML("https://www.cnbc.com/quotes/?symbol=XAU=","//table[#class='quote-horizontal regular']//tr/td/span")
Picture 3: List is shown when putting the code
After some tries, I am able to get the right target, but it confuse me, Im using this code =IMPORTXML("https://www.cnbc.com/quotes/?symbol=XAU=","//table[#class='quote-horizontal regular']//tr/td/span[#class='last original'][1]")
Picture 4: The right target is shown when the xpath query is more specified
As what you can see in 2nd Picture, 'last original' is not really the full name of the class, when I put the 'last original ng-binding' instead it gave me an error saying imported content is empty
So, correct me if my code is wrong, or accidental worked out somehow because there's another correct way?
How about this answer?
Modified formula 1:
When the name of class is last original and last original ng-binding, how about the following xpath and formula?
=IMPORTXML(A1,"//span[contains(#class,'last original')][1]")
In this case, the URL of https://www.cnbc.com/quotes/?symbol=XAU= is put in the cell "A1".
In this case, //span[contains(#class,'last original')][1] is used as the xpath. The value of span that the name of class includes last original is retrieved. So last original and last original ng-binding can be used.
Modified formula2:
As other xpath, how about the following xpath and formula?
=IMPORTXML(A1,"//meta[#itemprop='price']/#content")
It seems that the value is included in the metadata. So this sample retrieves the value from the metadata.
Reference:
IMPORTXML
To complete #Tanaike's answer, two alternatives :
=IMPORTXML(B2;"//span[#class='year high']")
"Year high" seems always equal to the current stock index value.
Or, with value retrieved from the script element :
=IMPORTXML(B2;"substring-before(substring-after(//script[contains(.,'modApi')],'""last\"":\""'),'\')")
Note : since I'm based in Europe, you need to replace ; with , in the formulas.
Hi I am trying to evaluate a variable from a file and a normal one but seems to be harder than it looks so :
This works:
{config_load file="archive_page.conf"
section="profile"} {include file="header.tpl" title=#pageTitle# keywords=#keywords# description=#description#}
I would like to also use my var and concatenate the text together so the below doesn't work also I have tried variations with '', "" but leads either an error message or one of the variables to display as text...
{config_load file="archive_page.conf"
section="profile"} {include file="header.tpl" title=#pageTitle#$MYVARHERE keywords=#keywords# description=#description#}
I tried various things but I can't get it to work, any help is much appreciated.
use the cat variable modifier:
title=#pageTitle#|cat:$MYVARHERE
I'm using openReports that uses freeMarker formats as a template.
The following:
<#display.table name="results" class="displayTag" sort="list" export=true pagesize=10 requestURI="queryReportResult.action">
<#display.column property="first_name" title="First Name" sortable=true headerClass="sortable" />
<#display.column property="last_name" title="Last Name" sortable=true headerClass="sortable"/>
</#display.table>
The data is automatically grabbed using a stored procedure.
This will create a sortable table, does anyone know how I could access just the first row of data. I intend to save it into a variable and output it in some part of the page.
The reason I want to do this is we have a basic report and what would make it perfect is if I could print some from it toward the top of the page above the report.
I know a lot of people aren't familiar with OpenReports, but I figured freeMarker does have a pretty good following. I understand if this is pretty obscure
From what I can see from here, the #display.table call prints the whole table at once, so there's nowhere to insert the FreeMarker code to catch the first row. But of course you should check the documentation of #display.table to see if it offers any helpful options. But, I suppose you have already done that. So as a last resort, you can capture the whole table into a variable with <#assign tableHTML><#display.table ...>...</#display.table></#assign> and then extract the first row with a regular expression (or something like that) from the value of the tableHTML variable.
I have a search form, and I want to create a "Start Over" link that just returns users to the page without any arguments. What Smarty code can I use? For example, if they are at http://website.com/search.php?value1=x&value2=y, I want to get http://website.com/search.php or just search.php, so I can construct <a href='{$string}'>Start Over</a>.
I would just fill a variable in your php that you send to smarty? you could get that in smarty I guess, but that's not really a good way. just do something like this:
$yourSmartyVar->assign("string",$_SERVER[’PHP_SELF’])
That should give you the scriptname without querystring if I remember correctly. If it doesn't you could use $_SERVER[’SCRIPT_NAME’] if that suits you better, or even use http://php.net/manual/en/function.parse-url.php
