|

Return the URL with some specific parameters inserted into the query
|
||||
part. If a URL has already some parameters, those requested will be
|
||||
modified if already exisiting or will be added and the other parameters
|
||||
will stay unmodified.
|
||||
|
||||
**Tag name**::
|
||||
|
||||
url_insert_param
|
||||
|
||||
**Parameters**:
|
||||
|
||||
url (optional)
|
||||
The URL to use as a base. The parameters will be added to this URL.
|
||||
If not specified, it will only return the query part of the URL
|
||||
("?a=foo&b=bar" for example).
|
||||
Example : "https://example.com/bar?foo=0&thing=abc"
|
||||
|
||||
other arguments
|
||||
Any other key-value argument will be used. The key is considered as
|
||||
the name of the parameter to insert/modify and the value is the one
|
||||
used.
|
||||
Example : q="foo" search="bar" name="johnDoe"
|
||||
will return as ?<existing_param>&q=foo&search=bar&name=johnDoe
