这是我的询问：
$results = $modx->query("SELECT contentid FROM modx_site_tmplvar_contentvalues WHERE tmplvarid=107");
我需要按菜单索引对其进行排序，所以我尝试了这个：
$results = $modx->query("SELECT contentid FROM modx_site_tmplvar_contentvalues JOIN modResource WHERE tmplvarid=107 ORDER BY menuindex DESC");
我对此一点也不熟悉。当然这是行不通的。有人告诉我使用 XPDO 但我对此一无所知。我错过了什么吗？我应该做什么才能让它发挥作用？
这是完整的代码：
<?php
$results = $modx->query("SELECT contentid FROM modx_site_tmplvar_contentvalues WHERE tmplvarid=107");
// description tv: 108
// vignette tv: 121
if (!is_object($results)) {
return;
}
$breves = array();
while($r = $results->fetch(PDO::FETCH_COLUMN, 0)){
$breves[] = $r;
}
$queryIn = implode(',' , $breves);
$results_2 = $modx->query("SELECT contentid, tmplvarid, value FROM modx_site_tmplvar_contentvalues WHERE contentid IN ({$queryIn}) AND tmplvarid IN (108, 121)");
if (!is_object($results_2)) {
return;
}
$tvValues = array();
while($v = $results_2->fetch(PDO::FETCH_ASSOC)){
if($v['tmplvarid'] == 108){
$tvValues[$v['contentid']]['desc'] = $v['value'];
} else {
$tvValues[$v['contentid']]['vignette'] = $v['value'];
}
}
$output = "";
foreach ($breves as $res_id) {
$page = $modx->getObject('modResource', $res_id);
$alias = $page->get('alias');
$id = $page->get('id');
$page_title = $page->get('pagetitle');
$description = $tvValues[$res_id]['desc'];
if(!$description || $description == ""){
$description = $page->get('content');
}
$description = strip_tags($description);
$description = mb_strimwidth($description, 0, 150, "...");
$vignette = $tvValues[$res_id]['vignette'];
if($vignette){
$vignette = "/assets/upload/pln/" . $vignette;
} else {
$vignette = "https://www.commune-ploudaniel.fr/assets/templates/pln/default-b7824fcd998f51baf0f0af359a72e760.png";
}
$output .= <<<HTML

$output .= PHP_EOL;
}
return $output;
尝试一下 MODX：
$q = $modx->newQuery('modTemplateVarResource');
$q->leftJoin('modResource', 'mr', 'mr.id = modTemplateVarResource.contentid');
$q->where(array(
'modTemplateVarResource.tmplvarid' => 107
));
$q->select(array(
'modTemplateVarResource.contentid'
));
$q->sortby('modResource.menuindex', 'DESC');
$q->prepare();
$q->stmt->execute();
$result = $q->stmt->fetch(PDO::FETCH_ASSOC);
print_r($result);
