Question

在我的搜索脚本中，我遇到以下代码的结果时遇到了麻烦：

    $sqlCommand = "SELECT `Loc.`, Model, Make, Description, `Tag No.`,
            MATCH(`Loc.`, Model, Make, Description, `Tag No.`)
            AGAINST ('$searchquery' IN BOOLEAN MODE) AS score FROM ag_combine
            WHERE MATCH(`Loc.`, Model, Make, Description, `Tag No.`)
            AGAINST ('$searchquery' IN BOOLEAN MODE) AND (Status='IN' or Status='OF') ORDER BY score DESC";

在搜索列到Tag No.列之前，查询工作正常，然后它会显示0结果消息;但是phpMyAdmin中的相同查询将产生所需的标签号结果。

我猜它与列名中的空格有关，但不确定如何从中正确选择。

以下是我正在测试的完整代码：

<?php
 include "includes/config.php";

error_reporting(E_ALL);
ini_set('display_errors', '1');
$search_output = "";
if(isset($_POST['searchquery']) && $_POST['searchquery'] != ""){
     $searchquery = preg_replace('#[^a-z 0-9?!+-]#i', '', $_POST['searchquery']);
     if($_POST['filter1'] == "Combines"){
        $sqlCommand = "SELECT `Loc.`, Model, Make, Description, `Tag No.`,
                MATCH(`Loc.`, Model, Make, Description, `Tag No.`)
                AGAINST ('$searchquery' IN BOOLEAN MODE) AS score FROM ag_combine
                WHERE MATCH(`Loc.`, Model, Make, Description, `Tag No.`)
                AGAINST ('$searchquery' IN BOOLEAN MODE) AND (Status='IN' or Status='OF') ORDER BY score DESC";     
    } else if($_POST['filter1'] == "Tractors"){
        $sqlCommand = "(SELECT `Loc.`, Model, Make, Description, Status, `Tag No.` FROM ag_tractor WHERE MATCH (`Loc.`, Model, Make, Description,`Tag No.` ) AGAINST ('$searchquery' IN BOOLEAN MODE) AND  (Status='IN' or Status='OF'))";      
    }

    $query = mysql_query($sqlCommand) or die(mysql_error());
    $count = mysql_num_rows($query);
    if($count > 1){
        $search_output .= "<hr />$count results for <strong>$searchquery</strong><hr />$sqlCommand<hr />";
        while($row = mysql_fetch_array($query)){
            $loc = $row["Loc."];
            $tag = $row["Tag No."];
            $model = $row["Model"];
            $make = $row["Make"];
            $description = $row["Description"];
            $search_output .= "$loc: $tag: $make $model - $description<br />";
        } // close while
    } else {
        $search_output = "<hr />0 results for <strong>$searchquery</strong><hr />$sqlCommand";
    }
}
?>

查询结果与PHPMyAdmin一起使用，但在PHP中返回0行
