How to create a quote encased variable from another variable.

Monday 04 October 2004 5:32:07 am

Hi there,

This is a new thread coming out of:

http://www.ez.no/community/forum/developer/dynamic_fetch_using_simple_form

I'm trying to encase a variable in quotes for fetch purposes... the eind result I' m after is:

let x=example
let encased_x='$x'
so that the value of $encased_x is 'example'

Paul B had given me some pointers but I wasnt able to get this working - does anyone have a past example or some ideas on this one?

Many thanks, Steve.

Paul,

Thanks for the reponse.

I tried the code, but it doesnt make any change - my variable stays the same. The full code I have is:

{let carat=ezhttp( 'search_carat', 'get' )}
{let clarity=ezhttp( 'search_clarity', 'get' )}

{let carat_in='('|concat($carat,')') 
let ecarat_in=concat('',$carat_in)

let clarity_in='('|concat($clarity,')')
let exactresults=fetch(content,tree,hash(parent_node_id, 59, 
attribute_filter,  
array(and,array('stone_product/carat','in','$carat_in'), 
array('stone_product/clarity','in','$clarity_in'))))
}
ecarat is {$ecarat_in} and clarity is {$clarity_in}

The line "{let carat_in='('|concat($carat,')')" encases the variable in brackets - perhaps I could introduce the quote here at the same time, but attempts so far have failed...

Of all the characters, the quote mark seems the most difficult to get in there.

Regards, Steve.

OK, The quotes are a bit difficult to generate. You will need additional concat("'") to make sure the strings are quoted inside the "array" (actually a string which build a SQL array like thing).

I upgraded kernel/classes/ezcontentobjecttreenode.php to version 3.4.2 (actually, the most recent in stable, but it works in 3.4.2).

Extra with this update: two more filter operators: between and not_between for integer/float ranges.

Hi Steve

I overlooked the fact that filtervalue strings are escaped in kernel/classes/ezcontentobjecttreenode.php

I corrected this in pubsvn and uploaded the corrected file in the contributions.

A working example in a production site here is as follows, and note the complicated concat to create the string:

{let myinstring=concat("('",'WP1.1',"','",'WP6.1',"')")
      test_fetch=fetch(content,tree,hash(parent_node_id,2,attribute_filter,array(OR,array('task/acronym','in',$myinstring))))}

My inistring: {$myinstring}
<ul>
{section loop=$test_fetch var=test}
<li>{$test.name}</li>
{/section}
</ul>
{/let}
