|push is used to add a value to the end of an array/table.

  • New in : SPIP 2.0

The |push filter is applied to a tag returning a PHP array/table (seer #ARRAY) and adds a new value to it.

The key is incremented by 1 for each new value. if no key has been defined for the first value, the table is indexed starting from 0 (the first key is 0).




[(#GET{an_array}|foreach)] displays:

  • 5=> one_value
  • 6=> another_value
  • 7=> a_third_value

The first key is 5 because it was specified during the creation of the table (the initial #SET command).

A common usage example of |push:

#SET{my_articles, #ARRAY}
#SET{my_articles, #GET{my_articles}|push{#ID_ARTICLE}}

If the articles selected by the (BOUCLE) LOOP bear the numbers 2, 5 and 10, [(#GET{my_articles}|foreach)] will return:

  • 0=>2
  • 1=>5
  • 2=>10

In this case, the first key is zero since there was no key defined beforehand.

In contrast to the PHP function array_push, the SPIP |push filter does not generate an error message if the filtered tag is not a table.
