php搜索脚本只能选择第一个单词

Question

作为问题，它只选择了我的product_name中以var_char（50）作为主键的第一个单词。

<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
$search_output = "";
if(isset($_POST['searchquery']) && $_POST['searchquery'] != ""){
    $searchquery = $_POST['searchquery'];
    if($_POST['filter1'] == "Whole Site"){
    $sqlCommand = "SELECT * FROM products WHERE MATCH (product_name ,details,category,subcategory) AGAINST ('".$searchquery."' IN BOOLEAN MODE)";
    } 
    require_once("storescripts/connect_to_mysqli.php");
    $query = mysqli_query($myConnection,$sqlCommand) or die(mysqli_error($myConnection));
    $count = mysqli_num_rows($query);
    if($count > 1){
        $search_output .= "<hr />$count results for <strong>$searchquery</strong><hr />$sqlCommand<hr />";
        while($row = mysqli_fetch_array($query)){
                $id=$row["id"];
            $product_name = $row["product_name"];
                    $details= $row["details"];
                $category=$row["category"];
                $subcategory=$row["subcategory"];
            $search_output .= "ID: $id <br/> Name: $product_name -<br/>$details<br />$category<br/>$subcategory<br/>
<a href='product.php?id=$id'>link</a><br/>

";
        } // close while
    } else {
        $search_output = "<hr />0 results for <strong>$searchquery</strong><hr />$sqlCommand";
    }
}
?>

这是因为它是主键吗？ 它实际上并没有为细节工作，它实际上很奇怪，没有为大多数单词工作，而是为某些单词工作..我完全感到困惑..它没有任何意义

<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
require_once("storescripts/connect_to_mysqli.php");
$search_output = "";

if(isset($_POST['searchquery']) && $_POST['searchquery'] != ""){
    $searchquery = $_POST['searchquery'];
    if($_POST['filter1'] == "Whole Site"){
$sqlCommand = sprintf("SELECT * FROM products WHERE product_name LIKE '%s%%'",
               mysqli_real_escape_string($myConnection, $searchquery));
    } 

    $query = mysqli_query($myConnection,$sqlCommand) or die(mysqli_error($myConnection));
    $count = mysqli_num_rows($query);
    if($count > 1){
        $search_output .= "<hr />$count results for <strong>$searchquery</strong><hr />$sqlCommand<hr />";
        while($row = mysqli_fetch_array($query)){
                $id=$row["id"];
            $product_name = $row["product_name"];
                    $details= $row["details"];
                $category=$row["category"];
                $subcategory=$row["subcategory"];
            $search_output .= "ID: $id <br/> Name: $product_name -<br/>$details<br />$category<br/>$subcategory<br/>
<a href='product.php?id=$id'>link</a><br/>

";
        } // close while
    } else {
        $search_output = "<hr />0 results for <strong>$searchquery</strong><hr />$sqlCommand";
    }
}

我也尝试了上面的代码，并缩小到product_name，它仍然没有显示，例如，如果我输入“ fish”，那么我将这个product_name输入为“ omega fish”，则没有显示任何内容，如果我输入了“ omega”，那么它作品

我已经放弃了这一点，并尝试使用LIKE函数，它似乎更好，但仍然很有趣。请对感兴趣的人参考此链接

适用于mySQL数据库的PHP搜索脚本，仅工作3个字母

谢谢

请参考用于MySQL数据库的PHP搜索脚本，只有3个字母有效，我认为这是一个类似的问题，只需将$ count> 1更改为$ count = 0或$ count> = 1
