我知道这似乎是重复的,出于stackoverflow等问题,但是我们开始了。
我正在尝试使一个SQL语句可以找到两个字符串之间的巧合
function getProductos($keyWords){ $keyWords = addslashes(strtolower($keyWords)); $keyWordsExploded = explode(" ",$keyWords); $sql = "SELECT * FROM PRODUCTOS WHERE HOMBRE_MUJER LIKE :keyWords OR CATEGORIA LIKE :keyWords" OR NOMBRE LIKE :keyWords; $query = self::$conn->prepare($sql); $query->execute(array(":keyWords"=> "%" . $keyWords . "%")); return $query; } In other part of the page I have this code: <?php if(isset($_GET['buscar'])){ require(PAGES_DIR . "queries_products.php"); $consultaProducts = new QueryProductos(); $productos = $consultaProducts->getProductos($_GET['buscar']); if($productos->rowCount()!=0){ $arrayProductos = $productos->fetchAll(PDO::FETCH_ASSOC); echo "<h3>Productos encontrados</h3>"; foreach($arrayProductos as $fila){ echo $fila['NOMBRE'] . " " . $fila['HOMBRE_MUJER'] . "<br>"; } }else{ echo "<p class='alert alert-warning'>No results found <strong>" . $_GET['buscar'] . "</strong>"; } } ?>
一切正常,在我的数据库中,我仅在CATEGORIA中存储2个值:“ hombres”和“ mujeres”,如果我搜索hombres,我将得到所有包含CATEGORIA hombres的记录,但是当我搜索hombres y mujeres时,我会得到没有结果,我尝试使用阅读过的不同句子,但是我没有任何运气,希望您可以帮助我解决此问题,从而大大节省我的时间。
试试这个:
function getProductos($keyWords) { $keyWordsExploded = explode(" ",$keyWords); $sql = "SELECT * FROM PRODUCTOS WHERE "; $likes = array("HOMBRE_MUJER", "CATEGORIA", "NOMBRE"); // build up our columns which will be used in our condition in sql statment $params = array(); // building up our sql statment and collecting our params foreach($likes as $like) { foreach($keyWordsExploded as $kw) { $sql .="$like like ? or "; $params[] = "%".$kw."%"; } } $sql = rtrim($sql, "or "); // trim the last "or" condition in sql statment $query = self::$conn->prepare($sql); $query->execute($params); return $query; }
