Hi guys,
I want to change my content when I click on a button. For example, I have a fetch function that fetch a couple of images from node 1 and if I click on a button I want to change that fetch function to fetch from node 2 and update my page in accordance.
Can anyone guide me on how to do that?
Thank you

Hi Ricardo,
1. you will need a variable e.g. '$fetch_parent_node_id' which you will use for the node id in your fetch
2. This variable has a default value
3. The variable should be possible to override by a POST or GET variable
Example for a get variable you can easily send by a custom Form or a custom link
URL with get variable ...?FetchParentNodeId=1234
{def $fetch_parent_node_id = 2} {if ezhttp_hasvariable('FetchParentNodeId')} {set $fetch_parent_node_id = ezhttp('FetchParentNodeId') } {/if} {def $node_list = fetch( 'content', 'list', hash( 'parent_node_id', $fetch_parent_node_id, ...))}
Hope this will help
Cheers Felix

Hi Felix,
Thank you for your help:
I tried something like this:
<form method="get"> <input type="text" name="FetchVariable"> <input type="submit" value="submit"/> </form> {if ezhttp_hasvariable('FetchVariable', 'get')} <p>The Variable exist</p> {else} <p>The variable dosen't exist</p> {/if}
When I reload the page (URL without the get variable) it writes: "The variable dosen't exist". Everithing ok here. But when I write down somethin on the text field and hit the submit button (the URL updates to ...?FetchVariable=something) the message remains the same.
Is this normal? The message should change to "The Variable exist" right?

If you do not reload the page you need ajax
1. a click performs an ajax call (php) the html result for example is insert into a fix html id
Have a look to this project which can do that
