SLT
je cherche a afficher un seul texte, le plus réssant, mais le problème c'est qu'il me sort tous la table du 1 id au dernier. voici mon code php
$smarty->compile_check = true;
$smarty->debugging = false;
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}

$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}


mysql_select_db($dbname, $link);
$query_Recordset1 = "SELECT acceuilID, Titre1, article1, titre2, article2 FROM table_motiv_acceuil ORDER BY acceuilID DESC";
$Recordset1 = mysql_query($query_Recordset1, $link) or die(mysql_error());

$totalRows_Recordset1 = mysql_num_rows($Recordset1);
#...your mysql connection & smarty initialization goes here
while ($row = mysql_fetch_assoc($Recordset1))
{
$id[] = $row['acceuilID'];
$titles[] = $row['Titre1'];
$article[] = $row['article1'];


}
$smarty = new Smarty();
$smarty->assign ('ids',$id);
$smarty->assign ('titles',$titles);
$smarty->assign ("articlesdroite",$article);


// Affichage du template après compilation
$smarty->cache_lifetime = 24 * 60 * 60;
$smarty->display('test.tpl');
?>


Voici le code TPL
{section name=id loop=$titles}
{$articlesdroite[id]}

{/section}

Merci pour votre aide

Vous voulez qu'il y ai qu'une seule lignée d'affichée ?

Si c'est le cas, rajoutez à la fin de votre requête un 'LIMIT 1' afin de ne ramener qu'un seul enregistrement :
Code:

SELECT acceuilID, Titre1, article1, titre2, article2 FROM table_motiv_acceuil ORDER BY acceuilID DESC LIMIT 1



Sinon , étant donné qu'un order by est gourmand en ressource, vous pouvez rechercher l'enregistrement le plus récent par sa date ou son id (je ne sais pas si vous avez des dates en base) avec :

    par son id :
    Code:

    SELECT
       acceuilID, Titre1, article1, titre2, article2
    FROM
       table_motiv_acceuil
    WHERE
       accueilID=(
          SELECT
             MAX(accueilID)
          FROM
             table_motiv_acceuil
       )

    par sa date (si vous en avez une, ici j'ai utilisé dateArticle) :
    Code:

    SELECT
       acceuilID, Titre1, article1, titre2, article2
    FROM
       table_motiv_acceuil
    WHERE
       dateArticle=(
          SELECT
             MAX(dateArticle)
          FROM
             table_motiv_acceuil
       )



Cordialement
