ich möchte Daten aus der Datenbank als Link anzeigen und gleichzeitig mit dem Suchtext farbig hinterlegen.
Jede der nachstehenden Funktionen funktioniert für sich einwandfrei.
- Code: Select all

?>
Die href-Funktion:
- Code: Select all
/*******************************************
* adds an a_href to one or more given title
* include an image, divided by ";"
*/
function title_href($name, $action) {
if (empty ($name) ) { return $name;
}
$name2 = explode (';', $name ) ;
$href = array();
foreach ( $name2 as $partname ) {
$partname = trim($partname);
$href[]=' <a target="_self" href=\''.$_SERVER['PHP_SELF'].'?action='.$action.'&title='.$partname.'\'>
<img src=\'img/button_select.png\' width=\'12\' height=\'13\' border=\'0\' alt=\' \'>'.$partname.'</a>';
}
return implode( ', ', $href );
}
Dazu der Aufruf:
- Code: Select all
$row['h_titel'] = "There´s a wind a-blowin´; Sweet wind";
$row['h_titel'] = title_href( $row['h_titel'], $action ) ;
switch ($phrase) {
case 'exact':
$row['h_titel'] = highlight ( $findtitle, $row['h_titel'] );
break;
case 'any':
case 'all':
default:
foreach ($words1 as $word) {
$row['h_titel'] = highlight1 ( $word, $row['h_titel'] );
break;
}
echo $row['h_titel'];
Keine der og. Kombinatione funktionert zufriedenstellend.
Wo zum [--Zensur-] liegt mein Fehler
