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>" . $_GET['buscar'] . "</strong>";
}
}
?>
一切正常,在我的数据库中,我仅在CATEGORIA中存储2个值:“ hombres”和“ mujeres”,如果我搜索hombres,我将获得所有包含CATEGORIA hombres的记录,但是当我搜索hombres y mujeres时,我会得到没有结果,我尝试使用阅读过的不同句子,但我没有任何运气,希望您可以通过帮助我解决此问题而大大节省我的时间。
最佳答案
尝试这个:
function getProductos($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;
}
