To dynamically replace the value of a GET parameter using Twig, you can use the app.request.query.get
method along with the url_query_append
filter.
For example, let's say you have a GET parameter named page
and you want to replace its value with the Twig variable newPage
. You can use the following code:
{% set newPage = 2 %}
<a href="{{ app.request.uri ~ '?' ~ app.request.query|merge({'page': newPage})|url_query_append }}">Next Page</a>
In this code, we first set the newPage
variable to 2 (which could be any dynamic value). Then, we use the app.request.uri
variable to get the current URL and append a question mark ?
to it.
Next, we use the app.request.query
variable to get an array of all GET parameters in the current URL. We merge this array with a new array that has the page
parameter set to the value of newPage
.
Finally, we use the url_query_append
filter on this new array to generate a properly-formatted GET parameter string and append it to the current URL.
This will generate a link that goes to the current page with the page
parameter set to the value of newPage
.
