Criteres and $GLOBALS

Monde en
#1

Hello dear SPIP Community.

I’m working on a project where certain information is defined in PHP’s the $GLOBALS variable at runtime.

It’s possible to create custom criteria for boucles, in « mes_fonctions.php » file.

However, even through the page I am opening in the browser is defining the $GLOBALS[‹ list_challenges ›] variable before the criteria is called in the boucle, the variable is empty inside the criteria.

Is it possible to work with GLOBALS inside criteria functions?

Example:

<BOUCLE_mission(MISSIONS){missions_completed}>

#ID_MISSION

</BOUCLE_mission>

The criteria is defined as such:

function critere_mission_completed($idb, &$boucles, $crit) {
$boucle = &$boucles[$idb];

$list_challenges = $GLOBALS[‹ list_challenges ›];

$boucle->where[] = array("‹ id_mission IN ($list_challenges) ›");

}

Expected: $list_challenges contains the global variable defied earlier.

Actual: $list_challenges is empty, as global variable is not defined for some reason.

Cheers,

Urs

Dont forget SPIP caches all of its results.
Criteria are evaluated once and wont be evaluated again whenever the global changes, but only when the cache expires.
Can't this explain your issue ?

so your solution probably depends on "when" the list_challenges is set or changed.

Example:

<BOUCLE_mission(MISSIONS){*missions_completed*}>

#ID_MISSION

</BOUCLE_mission>

The criteria is defined as such:

function critere_*mission_completed*($idb, &$boucles, $crit) {
$boucle = &$boucles[$idb];

 $list\_challenges = \*$GLOBALS\[&#39;list\_challenges&#39;\];\*

 $boucle\-&gt;where\[\] = array\(&quot;&#39;id\_mission IN \($list\_challenges\)&#39;&quot;\);

}

Expected: $list_challenges contains the global variable defied earlier.

Actual: $list_challenges is empty, as global variable is not defined for some reason.
