Issue: #1413 Branch: fix/issue-1413 Status: VERIFIED-FIXED (2026-09-12)

Every legacy test-plan import whose result contains a "test case / version does not exist" message logs 2× E_WARNING "Undefined array key 1" to the Event Viewer (events table, log_level=2, source GUI - Test Project ID : 1). The message comes from the compiled template

E_WARNING Undefined array key 1 - in .../gui/templates_c/..._0.file.planImport.tpl.php - Line 105

On the rendered page the affected rows show an empty status: ... : with nothing after the colon.

Triggered by the mixed-import repro (1 valid link + 1 missing-version link plus a missing-TC external id): each missing item adds one warning.

1. Login admin/admin on http://localhost:8082.
2. Fixture php tmp/fixtures_pimp.php: tproject 1 PIMP, tsuite 2, TCs Login(ext 1, v1 → tcversion 4)/Logout/Settings, plan 12 PIMP-Plan, platform 1 PIMP-Android.
3. http://localhost:8082/lib/plan/planImport.php?tplan_id=12 → choose tmp/pimp_xml/regr1390.xml (4 links: valid Login v1; Login v99; external id 777; no-platform link) → Upload file.
4. Before fix: the two "does not exist" rows render " :" (empty status); Event Viewer / events gains 2 log_level=2 rows E_WARNING Undefined array key 1 ... file.planImport.tpl.php - Line 105. After fix: every row carries a status — ... version 99 does not exist ... : Not imported, ... identified by 777 : Not imported — and zero new events.

Expected: no warnings in Event Viewer.

lib/plan/planImport.php builds the result map for {$gui->resultMap}. Every entry is expected to be a 2-element array array(message, status) — the Smarty template renders both unconditionally:

{foreach item=result from=$gui->resultMap}
    <b>{$result[0]|escape}</b> : {$result[1]|escape}<br />
{/foreach}

(planImport.tpl:58 → compiled planImport.tpl.php:105 htmlspecialchars((string)$_smarty_tpl->tpl_vars['result']->value[1], ...)).

Two appends produced 1-element arrays:

// :481 — "test case version does not exist"
$msg[] = array(sprintf($labels['tcversion_doesnot_exist'], $externalID, $version, $tprojectInfo['name']));

// :486 — "test case does not exist"
$msg[] = array(sprintf($labels['tcase_doesnot_exist'], $externalID, $tprojectInfo['name']));

Every other append in the file is 2-element (:241, :267, :355, :403, :422, :459, :475, :519). On PHP 8, dereferencing $result[1] on such an entry raises E_WARNING Undefined array key 1, which testlinkInitPage's event logger records in the events table.

Blast radius: the only producer of resultMap is lib/plan/planImport.php; the only renderer is planImport.tpl (dashio + tl-classic copies, both fixed by the producer change). 2 offender appends, 1 renderer.

Append the already-loaded $labels['not_imported'] status to both appends, matching the file's own convention for error/no-luck results:

$msg[] = array(sprintf($labels['tcversion_doesnot_exist'], $externalID, $version, $tprojectInfo['name']),
               $labels['not_imported']);
...
$msg[] = array(sprintf($labels['tcase_doesnot_exist'], $externalID, $tprojectInfo['name']),
               $labels['not_imported']);

• not_imported is already declared/loaded (:227) — no i18n bundle change.
• The message text and every other result row are untouched.

Rejected alternative:

• Null-guarding {$result[1]} in both templates — fixes the symptom but leaves the malformed data model in place and silently hides future producer regressions; the producer-side fix removes the warning at the source.

• primary repro (mixed regr1390.xml): every result row renders a status (Not imported for the two missing items), no more empty " :".
• event hygiene: baseline MAX(id)=5 (the two pre-fix E_WARNING rows); post-fix SELECT ... FROM events WHERE id > 5 → 0 rows.
• valid-link path intact: re-import of the already-linked Login v1 renders ... was already linked to Test Plan, only execution order has been updated.: OK (2-element, status shown) — no warning, no regression.
• php -l lib/plan/planImport.php clean; git diff --stat touches only lib/plan/planImport.php (+4/-2).
• Modern BFF comparator (static): the same 1-element defect exists at api/planimport/index.php:280,283 and renders undefined in the modern table's status column (no PHP warning — JS reads r[1] off the decoded JSON). Filed separately: issue #1461.
